How to Deal With a Faulty Furnace Blower Motor

How do you know if your furnace blower motor is faulty It is the middle of winter and you expect your home to be warm and cozy. Yet, you feel increasingly chilly. You go and check your furnace and realize that there’s no sound and airflow coming out of it. Your furnace blower motor has completely stopped working. Why has this happened? How do you bring your furnace back in good working order and ensure the comfort of your San Diego home?

There are numerous reasons why your furnace blower motor may have stopped working, some of which can be easily fixed while others may require assistance from furnace repair professionals.

How do you know if your furnace blower motor is faulty?

Just like many other HVAC components, the furnace blower motor is subjected to wear and tear that may cause mechanical failures over time. If your furnace keeps experiencing issues, the blower motor may be the culprit and might need to be replaced. Here are some signs you should look out for if you suspect that your blower motor is faulty:

  • Weak airflow: this is one of the first indications of a failing blower motor that you may notice. Check the airflow coming out of your vents – if it’s weak, the blower motor may be having a hard time distributing the air through the ducts in order to achieve the set temperature.
  • No airflow: if there’s no air flow coming out at all, your blower motor may be experiencing more serious issues and may need to be replaced, unless clogged air filters, incorrect settings, or a blown fuse are to blame.
  • High energy bills: the blower motor of your furnace is one of the components that use the most energy. If it’s old or faulty, it will work much harder to distribute the heated air throughout your home, causing your energy bills to spike.
  • Unusual sounds: hearing unusual noises coming from your furnace is rarely a good sign. Make sure to contact professionals if you notice screeching, squealing, rattling, banging, or clanking sounds coming from your unit.
  • Overheating issues: a blower motor might overheat due to a number of factors, including grime and dirt buildup and age. An aged and worn out blower motor will struggle to heat your home, causing it to overheat.

If you notice any of these warning signs, make sure to contact reliable HVAC contractors as soon as possible to prevent more serious damage and keep your furnace in good condition. However, make sure to attempt some of the easy fixes listed below before you go on to look for blower motor repair or replacement options.

What can cause a blower motor to stop working?

If your furnace blower motor isn’t working, the following culprits may be causing the issue:

Circuit breakers

A tripped circuit breaker or a blown fuse may cause your furnace to stop working. If this is the case, reset the breaker or replace the fuse to resolve the issue. Wait a couple of minutes and turn on the furnace to see if the blower motor starts working again.

Thermostat settings

It may be the case that your furnace blower motor isn’t working because the thermostat isn’t set appropriately. If the settings are too low, your furnace may think that you’re perfectly cozy at 50 degrees. Adjust the thermostat settings and check if that fixes the problem.

Air filters

Your furnace filters should be cleaned or replaced on a monthly basis during the heating season. If they aren’t, the accumulated dirt and debris may significantly decrease the airflow and prevent the blower motor from working.

Other issues

Some blower motor malfunctions will require professional assistance. The furnace capacitor may be failing or the blower itself may have a serious problem that requires servicing or a replacement. If none of the previously mentioned steps bring your furnace back to good working order, contact your HVAC professionals of choice.

How hard is it to replace a furnace blower motor?

If your blower motor is irreparable, a replacement is your only option. The replacement process can only be performed by a professional who is familiar with different types of furnaces and blower motors. HVAC experts can recommend a blower motor replacement suitable for your furnace, taking into account factors such as rotation direction, voltage, horsepower, capacitor size, motor diameter, and type of drive.

Once you’ve selected the best replacement for your furnace blower motor, your HVAC contractors will most likely give you a cost estimate and arrange the installation.

How much should it cost to replace a furnace blower motor?

Furnace blower motors can vary in cost depending on the model. On top of the cost of the blower motor itself, you’ll most likely also need to pay for the installation work, the cost of which will differ depending on the HVAC contractors you hire.

In general, HVAC blower motors tend to cost about $450 on average, while the replacement costs may range anywhere from $150 to $2,000. It won’t matter whether you have an electric heating system, a heat pump, or a gas furnace, as all of these units use air handler blower motors to push and distribute the heated air throughout the air ducts in your home.

Blown Furnace Fuse: What You Can Do

Why would a furnace fuse blow Has your home furnace blown a fuse or two? While you may think that a tripped breaker or a blown fuse may not be a big deal, there are several situations where you may risk complex failures unless you address the reason why your furnace keeps blowing fuses.

Since some of these reasons can be quite serious, it is advisable to reach out to furnace repair professionals if your heating system in San Diego keeps tripping breakers. In the meantime, keep reading to learn about the common culprits of blown furnace fuses.

Why would a furnace fuse blow?

Here are some of the most common reasons why your furnace may be blowing fuses:

Damaged wiring

Poorly connected and/or damaged wires can cause your furnace to short circuit and blow a fuse. If this is the case, it is generally best to let professionals inspect the wiring and resolve the issue.

Dirty air filters

A lack of maintenance can lead to dust and debris accumulating on the air filters. Unless the air filters are regularly cleaned or replaced, the grime may migrate to the blower motor, causing it to overheat and lead to a high limit failure. The best way to prevent this issue is to have your furnace maintained on a regular basis.

Thermostat metal frame

Thermostats surrounded by metal frames have been known to cause furnaces to blow fuses. This happens when the wiring inside the thermostat touches the metal frame, creating voltage issues and potentially blowing the control board. If this happens, you’ll have to reach out to professionals to fix the problem before being able to use the furnace again.

Worn or faulty components

When failing or faulty, the following furnace parts may cause the unit to short circuit:

If you suspect any of these furnace issues, don’t hesitate to contact your HVAC professionals of choice if you wish to prevent unnecessary damage to your unit and expensive repairs.

How do I know if my furnace fuse is blown?

Before you go looking for a new fuse, you should make sure that you’re actually dealing with a blown fuse and not some other issue. Checking your furnace fuse is a relatively simple procedure that won’t take much of your time. Still, reaching out to professionals to inspect your furnace may be the better cause of action if this isn’t the first time you’ve had this problem with your furnace.

Start by making sure that the furnace thermostat is set to “heat” and a suitable temperature. If so, check the power switch and see if it’s in the “on” position. If both of these are in order, it is time to check the breaker or fuse box.

Where is the fuse on a furnace?

In order to check and replace the fuse, you’ll first need to locate it. Hopefully, you already have an idea where the electrical panel is located and whether you have a circuit breaker or a fuse box. If you don’t, check your garage, basement or closet and try to find a grey metal box.

Circuit breakers

If your home has a circuit breaker box instead of fuses, each circuit breaker should be connected to rooms in your home or individual appliances. Your furnace most likely has a dedicated circuit of its own. The breakers are usually labeled, but if not, it will be quite easy to tell which breaker has tripped, as it will probably be in the opposite direction of the others.

Before you attempt to restore power, dry off your hands completely and flip the tripped circuit breaker with one hand. This should restore the power unless you’re facing a more serious issue with your furnace.


If your furnace has a fuse, it will probably be located in the control box with the blower. BIf you can’t locate it, the transformer may have burned up and will need to be replaced.

Once you’ve located the fuse, check its wires to see if they’re broken or look for signs of discoloration or cloudiness. If so, you have a blown fuse that will have to be replaced. You can also use a multimeter to check if the fuse is blown. A good fuse normally has nearly zero resistance (in ohms), whereas a blown fuse will show no reading.

How do I change a fuse in my furnace?

If you’ve determined that your furnace fuse is indeed blown, you’ll most likely be able to replace it quite easily. However, you’ll have to make sure to purchase a fuse that has the same wattage rating as the previous one. Check the manufacturer’s instructions manual to find information on how to properly replace the furnace fuse.

While most homeowners will be able to successfully replace a blown fuse, it is crucial that you contact experienced HVAC technicians to inspect your furnace system if it keeps tripping breakers or blowing fuses. This is because there may be a more complex issue causing the fuses to blow that might result in serious damage to your unit if not addressed properly.

My Heat Exchanger Is Broken: Do I Need to Buy a New Furnace?

Can a heat exchanger be replaced? Since cracked heat exchangers are associated with serious health risks, it’s no wonder homeowners look for an effective and quick solution when their heat exchanger breaks. How do you safely replace a heat exchanger? Do you have to replace the entire furnace if the heat exchanger is broken?

Hot summers and cold winter Inland Empire evenings can cause heating repair experts in Riverside to be overloaded with service calls and concerns about a heat exchanger replacement. Cracks in the heat exchanger can cause dangerous combustion gases to leak into your home, which makes immediate action necessary. However, the replacement process for a heat exchanger is not as simple as you may think, and we’ll explain why.

Can a heat exchanger be replaced?

A cracked heat exchanger is a serious cause for concern. If you’ve noticed that your exchanger is damaged, you will have little time to make a decision since carbon monoxide can leak into your home and cause harm to your health. HVAC professionals are capable of working immediately to resolve this major issue, or any others involving your heat exchanger.

Although it is possible to remove a damaged heat exchanger and replace it with a new one, this is not the most viable option for many homeowners due to the costs associated with the replacement process. Naturally, nobody wants to hear that they will need to purchase a new furnace. However, if the repair job costs more than half the price of getting a new system, purchasing a new furnace may be the better choice.

Due to the high costs of replacement and the risks of carbon monoxide leaks, most homeowners choose to replace the entire furnace instead of getting a new heat exchanger.

How much does it cost to replace a heat exchanger?

But how costly is heat exchanger replacement, exactly? While this will depend on the area you live, you can expect to pay anywhere from $1,500 to $3,500. This is due to the replacement process being intricate and taking up to 8 hours of labor to complete. Considering how time-sensitive dealing with a cracked exchanger is, it can be difficult to decide what the more financially viable option would be in your circumstances. Action is here to help! We offer upfront estimates, special financing and zero-down payment options. We promise to work with you to find the ideal system for your home and lifestyle.

Do I need to replace the heat exchanger or buy a new furnace?

If you’ve found yourself in a hurry to decide between replacing the heat exchanger or replacing the furnace altogether, ask yourself the following questions:

Is my furnace older than 10 years?

If your furnace is 10 or more years old, it is probably nearing the end of its lifespan. In that case, spending about $2,000 on replacing the heat exchanger wouldn’t be the smartest decision.

If you’re not sure about the age of your furnace, look for the furnace serial number. It is often written or engraved on a metal or paper tag which is often located on the furnace cover panel. Once you have the serial number, visit the manufacturer’s website and perform a quick search to determine the approximate age of the furnace.

If you are unable to find the serial number, you can also try contacting the company that installed the furnace and ask them when the unit was manufactured and installed.

Is the furnace able to properly heat my entire home?

Can your furnace meet your heating needs? Has it experienced any other problems such as frequent thermostat malfunctions or serious delayed ignition issues? There are numerous reasons why your furnace may be unable to keep every room in your home cozy and warm; these factors include incorrect sizing, improper installation, and old age.

Unfortunately, a furnace which cannot meet your heating needs currently, will not be able to meet them with a brand new heat exchanger installed either. If this situation sounds familiar, you most likely should consider replacing the exchanger or replacing the whole furnace.

Is my furnace under warranty?

Most manufacturers will offer extended “parts” warranties for furnace heat exchangers, which may range from 10 years coverage to a limited lifetime warranty. However, this type of warranty tends to only cover the costs of the heat exchanger itself, excluding the labor needed for the replacement. Since the replacement process can last for 8 hours or even longer, the labor costs may take up the bulk of the total repair cost.

The labor warranties offered by furnace installers tend to last between 1 and 5 years after the installation. If your furnace is under a labor warranty, replacing only the heat exchanger would be considered the better option, as the warranty will probably cover most of the repair costs. If the labor warranty has expired, however, you may want to consider replacing the furnace altogether.

If you’re unsure whether your furnace is still under warranty, make sure to contact the installation contractors. They will be able to tell you if your unit is still covered by the labor or parts warranty, and perhaps advise you on the best course of action in your situation.

The Causes of a Cracked Furnace Heat Exchanger

How long should a heat exchanger last? The heat exchanger is an essential part of your furnace. It is responsible for separating the combustion process from the air you breathe in your home, protecting you from dangerous exhaust fumes. Unfortunately, heat exchangers can break down over time, developing cracks and other issues that may affect their ability to keep the poisonous gasses away from your air.

If you suspect your heat exchanger is damaged and may need a replacement, make sure to reach out to reliable experts for heating repair in Riverside. In this article, you will discover some common causes for heat exchanger issues and learn how to tell if your heat exchanger is broken. Keep on reading.

How long should a heat exchanger last?

Modern heat exchangers are typically made from stainless or aluminized steel and tend to last up to 15-20 years. However, many factors may decrease the lifespan of heat exchangers, causing them to break down prematurely.

Considering the heat exchanger protects you from dangerous fumes created during fossil fuel combustion, such as carbon monoxide, it is essential that you address any heat exchanger issues immediately. If a heat exchanger is compromised by rust or cracks, these gases can leak into your home, causing illness or even fatal harm.

What causes a heat exchanger to go bad?

Metal fatigue is one of the primary reasons why a heat exchanger may crack. When the metal heat exchanger is heated, it expands as all metals do when heated. When the heat exchanger’s temperature begins to cool down, it contracts. This cycle is a normal part of the heating process. However, the constant metal expansion and contraction will eventually cause the heat exchanger to break.

A prominent reason heat exchangers are prematurely damaged is overheating. The reasons why a heat exchanger may overheat include poor system design, poor installation, and poor maintenance. When a heat exchanger overheats, the natural process of metal expansion and contraction speeds up, causing premature failure. Here are some specific reasons why your heat exchanger may crack:

Dirty air filters

Dirty air filters are one of the most common causes of heat exchanger failure. This is because a clogged filter will restrict airflow, causing the exchanger to overheat and suffer excess expansion and contraction stress. The heat stress may cause cracks to develop in the exchanger’s welds, bends, and other weakened areas.

Oversized furnace

A furnace that is too large for the home it’s installed in can also cause the heat exchanger to break. Here’s why:

  1. Water is a byproduct of the natural gas heating process. When a furnace is first lighted, the produced flame heats the exchanger and causes the water vapor to condense inside of it. When the heat exchanger reaches its operating temperature, the condensation evaporates.
  2. If the furnace is oversized, it will heat the home too quickly for the condensation to evaporate. This causes the heat exchanger to stay wet and rust over time  Additionally, an oversized furnace can also speed up the expansion/contraction process and increase the heat stress.

Undersized ductwork

A furnace that is installed with undersized ductwork will have restricted airflow. This scenario is similar to that caused by dirty or clogged air filters: the lack of proper airflow will cause the heat exchanger to overheat and experience excessive heat stress, which in turn results in cracks.

How do I know if my heat exchanger is failing?

Since heat exchanger issues can seriously affect your health, you should be aware of the most common signs and symptoms of heat exchange failure.

1. Cracks

Naturally, cracks are one of the most common and basic symptoms of a broken heat exchanger. Unfortunately, they are often also the most drastic symptom of heat exchanger damage, as cracks can cause the harmful combustion gases to leak into your home.

These cracks typically appear along the seams of the heat exchanger. Since they are not always visible to the naked eye, it is best to have HVAC professionals inspect your heat exchanger using infrared light detectors to discover cracks during regular maintenance tune-ups.

2. Odd flame behavior

If a heat exchanger is cracked, it will allow the furnace combustion air to mix with the heated air that is distributed throughout your home. This may cause odd changes in the furnace flame behavior, which can be detected by professional technicians. For instance, a flame that jumps and dances around after the blower fan is engaged may be an indicator of combustion air escaping through the cracks in the heat exchanger.

3. Discoloration

Tiny cracks in the heat exchanger can be incredibly difficult to notice with the naked eye. However, the soot that escapes through the crack may cause discoloration in the surrounding metal, which may be more easily detected. Look for dark spots on your heat exchanger and contact HVAC professionals as soon as possible if you happen to notice any.

In general, the best way to prevent and deal with heat exchanger issues is to hire professionals for routine maintenance and inspection. This will help you resolve any problems with your heat exchanger before they get out of hand and keep your furnace in good condition.

Delayed Furnace Ignition: Should You Be Worried?

What does delayed ignition sound like? Is there a reason to worry about the noises your furnace is making?

If your heating system is producing loud and explosive sounds, it’s a natural cause for concern.

Here is some important information about furnace delayed ignition and whether you should reach out to a heating contractor in Riverside to take a look at your heating system.

What does delayed ignition sound like?

When excessive gas builds up in the combustion chamber of your furnace, the delayed ignition will cause a small explosion. This results in a loud bang or boom that can be startling for homeowners. A similar sound can also be caused by expanding and contracting ducts.

What causes delayed ignition on a gas furnace?

You are most likely to notice a delayed ignition when you turn on your furnace, especially if you haven’t used it for a while. This is why delayed ignition usually happens in the fall or late spring when you don’t use it every day.

But why does it happen? In general, furnaces experience delayed ignition because a build-up of corrosion, dust, or sulfur blocks gas-feeding ports and prevents the burners from lighting properly. Here’s how it happens:

Moisture buildup

Over a period of furnace inactivity, moisture tends to build up inside your system, corroding its firebox over time. If the moisture-caused corrosion builds up enough, it can block the ports feeding gas into the furnace burners. If this happens, the burners won’t be able to ignite immediately after you turn the furnace on.

Dust and lint

While moisture and rust are one of the most common causes of delayed ignition in furnaces, dust and lint can also accumulate and cause problems. This can be easily remedied by having your furnace inspected and cleaned by professionals before each heating season.

Sulfur buildup

Your furnace can also experience delayed ignition due to a sulfur build up caused by burning natural gas. If your burners or pilot light are covered in a white layer, you may be dealing with built up sulfur.

Electronic ignition problems

If your furnace has an electronic ignition system, the delayed ignition may be caused by built up combustion gas in the chamber. While your furnace is most likely equipped with a safety mechanism to prevent this, the igniter may not come on promptly and shut off the flow of the gas, causing build-up. If this is the case, you’ll probably have to have the igniter replaced in order to ensure the proper functioning of your furnace.

Is delayed ignition dangerous?

A delayed ignition does not just sound like an explosion, it is one. If you choose to ignore these small gas combustions, it may become quite dangerous.

It may cause damage to your furnace

Unless properly addressed, the delayed ignition explosions are likely to get larger over time. The greater the vibrations are, the higher the chance of the stack pipe getting loose and soot ending up all over your home.

The excess flames caused by delayed ignition can also crack the heat exchanger, one of the most expensive components of your furnace. When this happens, most homeowners choose to replace the furnace instead of replacing the heat exchanger as the latter option is cost-prohibitive and the installation process may result in carbon monoxide leaks.

It may become a safety hazard

Constant gas build-ups in your furnace’s combustion chambers can not only damage your furnace, but may also let the flames out of the chamber and cause a fire. However, modern furnaces are built with mechanisms that uphold high safety standards. Essentially, the risk of explosions and fires will be slim if you properly and regularly maintain your furnace.

How can I prevent delayed ignition on a gas furnace?

Luckily, preventing delayed ignition is not difficult. All it takes is to have experienced HVAC technicians inspect and clean your gas furnace before each heating season, typically in the fall. This will prevent corrosion and dirt from accumulating inside of your furnace and minimize the risks of gas build-up. Here’s how professionals will clean your gas furnace:

  • Cleaning the surfaces: After wiping the exterior surfaces of your furnace with a damp cloth, they will vacuum the furnace base and the burners, as well as clean the dirt and grime from other components.
  • Cleaning the blower: Your technician will carefully clean your furnace’s boiler with a small brush and a vacuum, making sure not to disturb the fan blade counterweights and the wiring.
  • Cleaning the pilot or igniter: Since a dirty pilot light or surface igniter can cause problems with your furnace, your technician will make sure to carefully blow off any dust from these components without damaging them.
  • Cleaning the flame sensors: They will also lightly clean the flame sensor using an appropriate cloth to ensure optimal performance.
  • Lubricating components: When cleaning your furnace, your HVAC technicians will apply a tiny bit of lubricating oil on your furnace’s blower motor and shaft bearings.
  • Replacing the filter: You should have your furnace air filters replaced every 3 months. If you don’t want to bother with this yourself, your HVAC technician will do it for you.

Furnace Thermostats: Problems & Solutions

What's wrong with my furnace thermostat? Thermostat issues are one of the most common culprits of furnace malfunctions. If your furnace isn’t working as well as it should, and you’ve determined that other issues such as a faulty furnace heat exchanger or dirty air filters aren’t to blame, you should inspect and troubleshoot your thermostat.

We understand the importance of indoor comfort. Ensure your heating system stays in good condition, including on nights Riverside and other inland cities are colder during winter months.

What’s wrong with my furnace thermostat?

Thermostats are complex devices designed to control the operation of your furnace.  Learn about thermostat operation and what you can do to effectively resolve issues.

Unfortunately, there are a number of frustrating issues that may make your furnace malfunction or even fail. Here are five common causes of thermostat failure:

1. Dead batteries

Like any other electrical device, your thermostat needs batteries to work. If the batteries are dead, the thermostat won’t monitor the temperature and won’t instruct your furnace to turn on. If you notice a low power warning on your thermostat, try opening up the cover and replacing the batteries. Note that you should try using AA batteries instead of alkaline if you notice inconsistent performance. This is because alkaline batteries tend to drain quickly and cause failures in your heating system.

2. Grime buildup

Your thermostat may struggle to reach the set temperatures because dirt and grime have accumulated inside of it. If this is the case, your thermostat will be unable to accurately gauge the temperatures in your home.

If your thermostat is old, you should try dusting inside its cover and use a bit of paper to remove the grime from the contacts. However, the easiest and safest way to make sure your thermostat is clean and works well is to rely on professional HVAC technicians to inspect and maintain it.

3. Aged thermostat

You are likely to experience more issues with an old thermostat than you would with a modern device. Naturally, thermostats are prone to wear and tear, and there is a greater chance of breakdowns if your thermostat is reaching the end of its lifespan. If that’s the case, consider purchasing a programmable thermostat that will ensure the optimal performance of your heating system.

4. Loose wiring

Improper installation can often result in loose wiring inside of your thermostat, and in turn, weak performance and even severe electrical issues. It is essential that you don’t try to fix wiring problems in your thermostat yourself as this may cause even more damage to your heating system. Instead, contact your go-to technicians to fix or replace your thermostat.

5. Incorrect placement

Proper positioning is crucial for ensuring good thermostat performance. In order to work properly, your thermostat shouldn’t be placed in direct sunlight or next to a heat source and should be within 5 feet of any doors. This is important because it can cause your thermostat to read incorrect temperatures inside of your home.

How do I know if my furnace thermostat is broken?

Not sure if your thermostat is causing issues with your furnace? Here are some telltale signs of thermostat problems:

  • Your furnace won’t turn on. When a thermostat works properly, it allows you to turn on your HVAC system and change its settings. If you get no response from your heating system, it may mean that your thermostat is faulty.
  • The thermostat doesn’t acknowledge setting changes. If you attempt to change the temperature settings on your thermostat, it should respond to the changes almost immediately. If it doesn’t respond after you make the changes, you may need to have the thermostat fixed or replaced.
  • Your furnace short cycles. If your furnace turns off before finishing a full heating cycle, this means that it’s short cycling and might result in inconsistent or ineffective heating. If this happens, make sure to have your furnace inspected by professionals.
  • Your thermostat “forgets” programmed settings. If you have a programmable thermostat, it should be able to remember any programmed settings for long periods of time. If your thermostat forgets these settings, you may have to replace it.

While some thermostat issues can be replaced simply by replacing the batteries, it is always a good idea to contact HVAC professionals if you notice unusual behavior with your thermostat or heating system. This way, you’ll minimize the chances of severe breakdowns and keep your unit in good condition throughout the year.

How do you reset a furnace thermostat?

The procedure for resetting a thermostat may vary by model. While you can (and should) refer to your thermostat manufacturer’s resetting instructions, most thermostats can be reset in one of the following ways:

  • Flip the batteries: Installing the batteries backwards for five seconds and reinstalling them can be an effective way to reset your thermostat.
  • Flip the circuit breakers: Turn off the thermostat on the device itself and go to your circuit breaker box and flip the HVAC system breaker. Wait 30 seconds before you flip it back on and check if your thermostat is working properly.
  • Paperclip method: Use a paperclip to press the recessed reset button on your thermostat, if it has one. Hold the clip in for 5 seconds before releasing it.

Furnace Ignition Lockout: Causes & Solutions

What does ignition lockout fault mean? Is your furnace continually shutting down? Has it stopped responding entirely after several attempts to turn it on? If so, your furnace may be in an ignition lockout and must be reset.

Modern furnaces are equipped with a number of safety sensors used to keep the proper functioning of the unit in check. If any sensors detect an unsafe condition, the furnace shuts down to prevent safety hazards or damage to the unit. Unfortunately, the furnace will remain in this state until you or your local Murrieta heating repair technician reset it manually.

What does ignition lockout fault mean?

When a sensor detects an unsafe condition, the furnace controller will shut off the power and fuel to prevent hazards. This is known as an ignition lockout, a condition that can be caused by a number of different sensors found in your furnace. If your furnace is locked out, it will most likely remain in that state until it’s reset. Many homeowners send their furnace into a locked out state when they attempt to get it running several times in a row without success, unaware that the sensor has detected an unsafe condition.

What causes furnace ignition lockout?

Most of the time, furnaces go into ignition lockout because of issues with flame sensors, igniters, or limit switches. Here are the most common lockout culprits explained.

Defective flame sensor

Defective flame sensors are one of the most common causes of lockouts. When your furnace begins to start, the sensor checks for the presence of fire. If the sensor is faulty or dirty, it won’t be able to detect the flame and the controller will stop the ignition sequence. Most modern furnaces will let you start the furnace two more times before it goes into a lockout.

Faulty igniter

The igniter is another frequently encountered lockout culprit. If your furnace igniter does not activate within a couple of seconds, the flame sensor won’t detect the flame, and the controller will stop the furnace from starting. After the third attempt, your furnace will most likely go into a locked-out state. If your gas furnace has a pilot light, the lockout may also be caused by its failure to light the main burner.

Limit switch response

Your furnace also has a limit switch that monitors heat exchanger temperatures and fuel pressure. If the temperature is too high or the pressure too low, the limit switch will close, instructing the furnace to shut down and enter lockout mode. A dirty filter may also cause the limit switch to trip by reducing the air flow. If you have a modern furnace, you may be able to tell what caused the lockout via the status code lights.

What is the difference between a hard and soft lockout?

There are two main types of furnace lockouts you should know about – a hard and a soft lockout. As we’ve already explained, your furnace controller will stop the ignition sequence and prevent unsafe operation if the sensor doesn’t detect the flame within a set time period. This semi-shutdown is known as a soft lockout, and you will be able to attempt to start the furnace again, usually two more times.

A hard lockout happens after several repeated soft lockouts. For most furnaces, you will have three attempts to relight the unit before it goes into hard lockout. If this happens, you will have to reset the unit manually. The best way to do this is by calling your go-to HVAC technicians to perform the reset sequence.

How do you fix a furnace ignition lockout?

The exact procedure for getting your furnace out of lockout will depend on the culprit. Here’s what you can do before resetting your furnace:

  • Clean or replace the flame sensor: Inspect the furnace flame sensor to look for cracks and signs of damage. If you notice only soot or slight corrosion, follow our guide on cleaning flame sensors. If that doesn’t fix the problem, replace the sensor and try again after you restore the furnace from lockout.
  • Clean or replace the air filter: A clogged air filter can prevent adequate air supply to the system, tripping the limit switch. Simply replace the filter and see if the issue has been resolved. It is generally advisable to replace or clean furnace air filters regularly to ensure the safety of your family.
  • Inspect and clean the vent pipes: Look for debris and signs of obstruction inside your vent pipes and clear any blockage you find. If you are unable to clear the blockage, the best course of action would be to call HVAC experts to replace the clogged pipe section.

Resetting the furnace

Regardless of the culprit, you will have to perform a reset procedure to get your furnace out of lockout. Most modern gas furnaces can be reset by turning off the power, waiting around 20 seconds, then switching the power back on. Other furnace models may exit lockout after 1-2 hours and attempt to power on again. If your furnace has a pilot light, you may need to relight it following the manufacturer’s instructions.

If none of the above-mentioned works for you, the best course of action is to reach out to knowledgeable HVAC technicians and have them inspect your unit and perform the necessary tests and repairs to get your furnace out of lockout.

Furnace Flame Sensor Faults: All You Need to Know

Do flame sensors wear out? Does your gas furnace shut down shortly after you turn it on? Does this happen several times before the furnace shuts down completely? If that is the case, you may be dealing with a furnace flame sensor problem.

Flame sensors are simple devices designed to confirm the gas valve is only open when there is a fire present, preventing harmful gas buildup. These sensors are typically found in modern furnaces, and other gas-fired heating systems.

Fortunately, problems with flame sensors are a common occurrence among homeowners, and don’t often require complex heating repair. The following brief guide can help you determine if your furnace flame sensor is dirty or faulty, and whether you need expert HVAC assistance in Murrieta.

Do flame sensors wear out?

Flame sensors wear over time. However, often the problem is a dirty sensor, rather than a broken one. Since these sensors are designed to have a low tolerance for reading variations, they might misread from the slightest carbon coating. As most furnaces are located in dusty areas, such as basements or laundry rooms, the airborne particles can easily stick to the flame sensor, burn and cause carbon buildup.

What happens when a flame sensor goes bad?

If cleaning the sensor doesn’t restore your furnace to working condition, a replacement may be in order. If this happens, it is advisable to contact a professional HVAC service provider to inspect your furnace and resolve the issue.

Without a flame sensor, your furnace will keep emitting gas even when there’s nothing to ignite it, resulting in hazardous gas buildup. If your flame sensor is dirty or faulty, it will automatically shut down the heating unit if it doesn’t detect a flame.

Most furnaces will go into a safety ignition lockout when a shutdown happens three times. In addition to being highly inconvenient, continuous tampering with a bad furnace flame sensor can cause issues with other furnace parts and reduce overall efficiency.

How do I know if my furnace flame sensor is bad?

Not sure how to tell if your flame sensor is faulty or just dirty? Follow these guidelines to determine which is true:

  • Switch off the power to your furnace
  • Close the gas valve
  • Take out the mounting screw
  • Carefully pull out the sensor
  • Inspect the sensor: if the insulation is intact but appears sooty, burnt or slightly corroded, it might only require cleaning
  • If the sensor insulation is missing pieces or cracked, a sensor replacement is needed

Replacing a flame sensor is a simple procedure, but it’s advisable to outsource the job to professionals, lowering risk for preventable issues. HVAC experts can also thoroughly inspect your unit to determine any additional problems and prepare your heating system for the upcoming winter season.

What can I use to clean a furnace flame sensor?

It is likely that your flame sensor problem can be fixed with a simple cleaning. The easiest way to do this is to rely on your preferred HVAC technicians in Murrieta to clean the sensor during your regular furnace tune-ups. If you decide to do it yourself, you’ll need:

  • Wrench or driver to remove the 1/4  hex screw (exact tool needed may depend on the type of screw)
  • Light grain sandpaper, steel wool, or a wire brush
  • Clean and dry cloth or paper towel

First, shut off the power to the furnace and locate the sensor in the burner assembly. It is a thin, typically bent, metal rod placed in front of the furnace flame stream. Once located, use the driver or wrench to remove the screw and access the sensor. Next, use the sandpaper, steel wool, or wire brush to rub the rod gently and remove the carbon buildup, making sure you don’t go overboard. Once you’re done cleaning, use the cloth or paper towel to wipe the rod down.

How do you test a flame sensor?

During routine furnace tune-ups and check-ups, your HVAC technicians will troubleshoot your flame sensors to ensure proper performance and safe functionality, as well as prevent more serious damage to the unit. Here’s how it’s done:

  • Step 1: Unplug the device and locate the sensor. If the unit can’t be unplugged, use the breaker found in the breaker box to switch off the power.
  • Step 2: Use a driver or wrench to unfasten the screw that holds the flame sensor in place and carefully pull it out.
  • Step 3: Use a multimeter to show resistance by touching the probes to the white and blue wire ports found on the sensor. The device should detect low resistance.
  • Step 4: Take the flame sensor and press its open end against a test lamp or a 60 watt bulb. Check the multimeter and see if it shows high resistance.
  • Step 5: If the multimeter doesn’t detect a resistance discrepancy when placing the open end on a light source, the flame sensor will have to be replaced.

What makes a good heating and cooling company?

So, what makes a great heating and air conditioning company? Homeowners tend to look for the following characteristics when searching for HVAC contractors:

Trained & certified technicians

Reliable heating and cooling technicians should have all the necessary training and certification. Although experience is another important factor, seeing that your HVAC technicians are certified and properly trained shows that they have the knowledge and skill needed to repair, replace, or install your heating or cooling system properly.

For instance, NATE-certified technicians possess both theoretical and real-world knowledge of all kinds of HVAC equipment. If you want to make sure that your HVAC contractors are competent, make sure to check if they have any sort of certification that may prove their expertise.

Experience with a wide array of HVAC systems

There are a multitude of HVAC systems available on the market today. A good heating and cooling company should be able to adapt their approach depending on the type and model of your system. Whether you have a ductless air conditioning system or an older furnace, a knowledgeable technician should know how to repair or replace it expertly and efficiently.

Additionally, your contractors should offer maintenance and tune-up programs for both your cooling and heating system if you wish to stay comfortable all year round. Of course, not all HVAC companies service all kinds of equipment, so make sure to check this first before you hire.

Honesty and integrity

Contractors who respect their customers and value their trust tend to put more effort into perfecting their services. Your HVAC company should strive to meet your needs and surpass your expectations with each visit, whether you are a first-time customer or a long-standing client. Their dedication to making you happy should never waver.

Personable customer service

An amicable and dependable customer service staff is a must for any serious heating and cooling company. Even if the technicians are highly skilled and experienced, you surely won’t appreciate their expertise if the rest of the team is not willing to listen to your feedback and address your concerns.

In fact, good customer care is one of the most important areas that any HVAC company could work on. You should look for contractors who are dedicated to building loyalty and trust with their customers, listen to what you have to say, as well as keep you in the loop regarding any fixes they perform in your home.

Great prices & financing options

The cheapest heating and cooling company is rarely the best. Reputable HVAC contractors should offer you reasonable prices for their services, as well as give good guarantees on their work. Of course, some HVAC contractors overprice their services, so make sure to ask around if you’re not sure about the quality they bring to the table.

Additionally, your HVAC contractor should offer a number of financing plans that fit your budget and give you the best value for your money. For instance, they might offer no money down financing options for some of their equipment.
