Problems With the Furnace Transformer: What You Should Know

What causes a furnace transformer to blow Your home furnace has a transformer that regulates your home’s voltage to accommodate the system’s power output. Just like any other component of an HVAC system, your furnace transformer may fail and cause problems with the functioning of your unit.

If you suspect that your furnace transformer has broken down and wonder if you should begin searching for the best furnace repair company in San Diego, it would be a good idea for you to get an idea of its overall purpose in your furnace. In this article, we will explain what the transformer is, how it works, and what may cause it to break down.

What is a furnace transformer?

A furnace transformer is a device designed to decrease or increase the voltage of an alternating current (AC) to make it suitable for use in your heating system. It transfers electrical energy from a circuit to another using electromagnetic induction. The main role of a transformer in a furnace is to regulate the incoming voltage to meet the system’s requirements. Depending on the amount of power needed by the furnace, the transformer can diminish or amplify the electricity usage. In an HVAC system, the transformer is typically located inside your furnace, but it may be located in your outdoor AC unit in some cases.

What causes a furnace transformer to blow?

Your furnace transformer may fail due to several reasons, including the following:

  • Faulty contractor: a bad contractor is one of the most common causes of a blown transformer. This is because a faulty contractor can put the entire system under stress, causing the transformer to blow once the tension becomes too much.
  • Wiring problems: if there are loose cables or wires inside your transformer, they may cause a short circuit, frying the transformer.
  • Power surges: similarly, a power surge may also cause your transformer to blow, resulting in problems with the entire unit.

How do I know if my furnace transformer is bad?

If you suspect that your HVAC transformer is faulty, you may want to look out for the following signs and symptoms.

Visual signs

Sometimes, performing a visual inspection of your furnace transformer can help identify issues with the equipment right away. For instance, if you notice any burn marks or bulges along the exterior, it is likely that the transformer needs to be replaced. If you do notice any visual damage, do not try to test the unit yourself. Instead, contact a professional HVAC contractor to inspect your unit and determine the right course of action. If you attempt to test or repair the unit yourself, you may cause the unit to overheat and break down completely.

Vibrating and humming sounds

It is normal to notice a humming sound in your transformer. This is because the iron core or the laminations of the transformer expand and contract, producing a humming sound. However, if you notice a drastic increase in humming accompanied by vibrations, your transformer may be faulty. Also, you should keep in mind that the humming sound may be the result of other issues, such as a faulty furnace capacitor. This is why it’s usually best to have a professional technician inspect your furnace and see what the problem is.

Tripped circuit breaker

If the transformer of your furnace is faulty, it will usually cause the circuit breaker to trip in order to prevent a voltage surge. A surge of voltage may fry various components of your furnace, causing serious damage. If the circuit breaker keeps tripping or if your furnace keeps blowing fuses, the transformer may be the culprit.

Furnace not working properly

If you have a bad transformer, your furnace may not work even with an appropriate power supply. The system does this to protect itself from severe damage caused by electrical issues. Unless you’re an expert, it’s unlikely that you’d be able to confirm with certainty that your furnace is malfunctioning because of a faulty transformer. If you can’t get your furnace to work, make sure to contact a reliable HVAC company to have it inspected.

What happens when a transformer goes bad?

When the transformer in your furnace breaks down, the unit will receive weak power or no power at all. You can check whether there’s power to your unit by turning it off and on again. If there is very little power or none at all, you may need to have the unit replaced or repaired. Alternatively, can also check the voltage points of your furnace. If the voltage is weak or non-existent, there may be several causes, such as a faulty control board.

Can I Replace The Transformer Myself?

Unless you are a qualified and experienced technician who knows a lot about HVAC transformers, you may be able to perform the replacement yourself. If you are a homeowner who has no experience with repairing furnaces, we strongly advise you against attempting to repair or replace the transformer. Think about this: would you rather pay a trained and reliable technician to perform the job according to the latest industry standards? Or would you rather risk damaging your furnace and paying for a new unit? Answering these questions should be enough to help you decide.

How to Tell If Your Furnace Capacitor Is Faulty

How long do furnace capacitors last The capacitor is a small, yet important component of your furnace. It is designed to ‘jumpstart’ the unit by giving the furnace blower motor an extra jolt of energy and getting the fan running. Just like any other part of the furnace, a capacitor may break down and cause your furnace to stop working.

If you are wondering whether you need to contact heating system repair experts in San Diego County to inspect your furnace capacitor, you’ve come to the right place. In this article, we discuss the common signs of a faulty furnace capacitor to help you determine whether you need a replacement.

How long do furnace capacitors last?

Modern furnaces have capacitors that are designed to last anywhere between 10 and 20 years. However, a variety of factors may decrease the lifespan of a capacitor, such as:

  • Prolonged heat exposure: if a capacitor is exposed to heat for a long period of time, it may become susceptible to damage. To prevent this, place your furnace under the shade, minimizing the time it spends in the sun, maximizing durability.
  • Incorrect voltage ratings: homeowners may attempt to replace their furnace capacitors themselves, and sometimes choose a cheaper capacitor that doesn’t match their unit’s correct voltage rating. This may greatly decrease the lifespan of the capacitor and even lead to system failure.
  • Improper installation and sizing: a capacitor that is undersized or installed with the wrong parts may not last long and cause problems with the entire unit. This can be avoided by relying on experienced HVAC technicians for the installation.

What are the signs of a bad capacitor?

Your furnace has a blower motor that blows the hot air into your home via ductwork. In a way, a furnace capacitor functions as a battery, storing the energy required for the blower motor to work well. If a furnace capacitor is faulty, the blower motor won’t function properly and may compromise your family’s comfort.

A faulty furnace capacitor may exhibit several signs, including:

No power

A broken furnace capacitor will prevent the functioning of the blower motor, causing the unit to stop working completely. Before you can determine whether the capacitor is the root cause of the problem, you should check the fuse controlling your furnace and see if it’s on. Once your furnace receives power, increase the thermostat settings and see whether the blower motor starts working within a couple of minutes. If there’s no response, the capacitor is most likely the cause.

Inconsistent blower motor operation

The capacitor needs to be in good condition for the blower motor to function properly. If the capacitor is bad, the blower motor may run slowly or inconsistently, or overheat easily. If you notice that your blower motor works strangely or short cycles, make sure to contact professionals to inspect your capacitor.

What does a bad furnace capacitor sound like?

You can also tell whether your furnace capacitor is working properly by listening to the sounds it creates. If a capacitor produces humming sounds, it may be a sign that is experiencing electrical issues. To check if this is the case, make sure to turn up the furnace thermostat and wait for the blower to start working. Next, use a screwdriver to open the access panel and lean near the blower housing to listen for a humming sound. If you hear it, make sure to reach out to HVAC professionals to inspect the unit.

How often should capacitors be replaced?

Capacitors are actually one of the most common components that are replaced on furnaces. They are usually designed to provide 10-20 years of service, but various factors discussed in this article may decrease their lifespan. If you’ve had your furnace for more than 10 years, it is likely that you’ll have to replace the capacitor at least once.

Testing the furnace capacitor

Start by shutting off the power to your unit at the fuse. Remove the housing of the blower motor to gain access to the capacitor. Even if there’s no power, the capacitor still holds a charge. Make sure to remove the wiring from the terminal and follow the manufacturer’s instructions for your furnace to discharge the capacitor. Use a voltmeter and set it to the X1 setting. You can find the voltage rating for your capacitor on its side, in most cases. Touch the voltmeter probes to the capacitor terminals and check if the voltage matches its rating. If it doesn’t match, you’ll need to have the capacitor replaced.

If you notice any of the signs of a bad capacitor discussed in this article, contacting professionals should be your next step. Not only are experts better qualified to size and install a new capacitor properly, but they may also check your furnace for any other potential issues, such as a faulty furnace transformer. We strongly advise you against trying to perform any furnace repairs yourself as this may result in more serious damage.

How to Run & Maintain Your Furnace During Winter

How often should you do furnace maintenance It’s important to know how often you have to maintain your furnace if you want to maximize its longevity and ensure it serves your home for as long as possible. Regular routine furnace maintenance will also enable it to perform better during winter and provide improved comfort for you and your family during the coldest of months.

Homeowners also need to know how to adequately run their furnace during winter. This will minimize strain on the unit and to prevent it from breaking down quicker due to increased wear and tear stemming from inadequate use.

However, you need to be aware of the fact that even with adequate maintenance and servicing by experienced air conditioning and heating service experts from Murrieta, CA, you will still eventually have to replace your furnace. But, let’s see how you can postpone it.

How often should you do furnace maintenance?

All manufacturers of furnaces strongly advise homeowners to have qualified HVAC technicians perform routine furnace maintenance once every year. Also, there is usually verbiage in the manufacturer’s warranty that states that any problems that stem from lack of proper maintenance is not covered by the company.

Regularly maintaining your furnace will help it operate at an optimal level, prevent any serious problems from arising, and increase its lifespan. The standard furnace inspection and maintenance procedure usually involves the following actions:

  • Checking the venting system for proper slope and potential blockages.
  • Combustion analysis to inspect carbon monoxide levels.
  • Inspecting the heat exchanger.
  • Testing all the safety switches to ensure they’re functioning well.
  • Checking if the burner ignites adequately.
  • Inspecting the combustion blower for blockages, amp draw, and bearing noises.
  • Testing the main blower.
  • Cleaning the drainage system.
  • Checking all the wiring for corrosion and proper connections.
  • Confirming sufficient gas pressure.
  • Inspecting the filter and changing it if necessary.

How often should your furnace run in the winter?

Winter poses a true test for your furnace, as cold temperatures can really put a strain on your heating system. That is why you need to pay attention to your furnace run times. Sometimes, the heating cycle can indicate that your furnace is struggling and that there may be something wrong with it.

However, it is also worth noting that there are several different factors that can affect the duration of your furnace’s heating cycle. Let’s take a look at all the reasons why the heating cycles of your furnace might be varying:

  • Outside temperature: The colder it is outside, the sooner your indoor temperature drops, causing your furnace to fire up again to compensate for the heat loss. Although good insulation helps with minimizing the heat loss, your furnace can still run for longer.
  • Thermostat temperature: Setting the temperature on your thermostat can also affect the duration of the heating cycle. If you set the temperature closer to the operating limits, it will take a longer heating cycle to maintain the desired temperature.

These are the two most important factors that affect furnace run times. However, if there aren’t any extreme factors involved, your furnace should run approximately ten to fifteen minutes per cycle. If you notice that your furnace is constantly running shorter or longer cycles, it might mean there is a problem with it.

How long should a furnace last?

A furnace that is maintained properly and by professional HVAC technicians should last anywhere from 15 to 20 years, or longer. Doing all you can to keep your furnace in good condition will greatly reduce potential for serious breakdowns and significantly increase its longevity.

However, there still comes a time when replacing your furnace is inevitable. The usual wear and tear will take its toll, and you will have to replace your furnace. Take a look at the following signs that your furnace needs to be replaced in order to know when it’s time to purchase a new one:

  • Your energy bills are rising.
  • The temperature in your home is not comfortable.
  • You’re constantly hiring technicians to repair your furnace.
  • There are strange sounds emanating from the furnace.
  • You notice yellow flame in your furnace.
  • The air flow is getting weaker.
  • There is a lot more dust around your home.
  • There’s rust, corrosion, and cracks.

How to Get Your Furnace Ready for Winter

How do I prepare my furnace for winterA fully functional furnace is your best ally throughout winter. Every year, your heating system works tirelessly to keep you warm and cozy on chilly winter nights. To keep it running smoothly and faultlessly and ensure your family’s comfort and safety, take care of maintenance before winter rolls in.

For the best, most precise, and highly efficient furnace maintenance, contact a dependable heating and air conditioning service in Murrieta. The experts will inspect your furnace and promptly resolve all issues they encounter, maximizing its efficiency.

How do I prepare my furnace for winter?

Since you’ll run your furnace regularly throughout winter, you have to be certain that it’s in great working condition. Here are several steps you can take to ensure your furnace is operating properly:

  • Change the filter: Your furnace has an air filter which needs changing each couple of months. Otherwise, it will get dirty, reducing the efficiency of the furnace and shortening its lifespan in the long run.
  • Oil the blower: The blower is an essential element of your furnace, which has to be lubricated once a year to keep the furnace operating well.
  • Clean the burners: Your furnace hasn’t been in use for a while, which means that a lot of dust has collected on its components. The dirt that’s accumulated on the burners can cause a weird smell when you run the furnace. Clean them carefully and inspect them for corrosion or irregularities.
  • Check if the heating vents are exposed: Make sure that nothing is blocking your heating vents. For example, a piece of furniture could be standing in the way, preventing the warm air from circulating the room and even increasing the risk of a fire.
  • Clean the chimney and vents: Dirt, soot, and debris may collect in your vents or chimney, making them unfit to use. Clear them out thoroughly before the start of winter.
  • Switch on the thermostat: Change the thermostat from cooling to heating and do a test run. Pay attention to the temperature for the next few minutes to check if the house is warming up like it should.
  • Look for signs of strange odor or noises:  Although these may only indicate that the furnace is picking up the pace after being off for a while, they may also point to issues. If you suspect there may be a problem, contact your HVAC experts.

Although some of these can be done by the homeowner, it is highly advisable to put a trained HVAC professional in charge of the upkeep of the furnace. HVAC experts are trained and experienced in the field, so they may spot malfunctions more accurately, as well as carry out suitable repairs without fail.

When should you turn your furnace on in the winter?

To maintain a healthy and comfortable room temperature, you shouldn’t turn on your furnace before the temperature drops below 68°F. Start at a lower temperature and turn it up gradually until you reach the optimum. Bear in mind that going up by one degree only uses up to 15 percent more energy than before. Don’t overheat the place – rather, try setting the thermostat as low as possible. If you’re interested, learn more about achieving energy efficiency by setting your thermostat wisely.

What Are the Properties of a Bad Heating Element?

How do I know if my heating element is bad in my furnace If your heating element malfunctions, it can lower the heating capability of your system and compromise the comfort of your home. This is definitely not something you want happening to you during a cold winter night.

However, it is sometimes a bit difficult to determine if your heating element is going bad. It is a wise choice to be familiar with all the signs, so you can react before things get out of hand.

It doesn’t hurt to know more about the underlying reasons that cause the heating element to burn out, so you can prevent it from happening. But, let’s first take a look at all the signs that indicate you need to contact reputable air conditioning and heating repair professionals in Temecula.

How do I know if my heating element is bad in my furnace?

A heating element, also frequently referred to as heat strips, is a component of your furnace that helps heat the air in case your heat pump is unable to convert the air from the outside into warm air quickly enough.

Heating elements are vital components of furnaces because heat pumps rely on taking the heat from the outside air, increasing its temperature, and distributing it further through the system and into your home.

The problem occurs when cold temperatures make it more difficult for the heat pump to operate on its own, requiring additional heat sources to help with the process. This is why a heating element is an essential component of a furnace.

However, the heating element in the furnace can malfunction and go completely dead. The easiest way to check this is to turn the heating element on and inspect the temperature of the air coming out of your heating system.

If the air is insufficiently heated, very close to, or at room temperature, there is probably something wrong with the heating element. However, you should refrain from doing this procedure on your own due to danger of electric shock. Always consult a qualified HVAC technician before deciding to diagnose a problem with your furnace alone.

What causes a heating element to burn out?

Heating element is a gentle part of your furnace, and there are several things that can make it burn out. There are preventative actions you can take to prevent it from happening. However, some underlying causes request assistance from an experienced HVAC technician.

Here are the most common causes of a burned-out heating element in your furnace:

  • Faulty Wiring: Problems with the wiring within your furnace can cause inadequate amounts of electrical power to your heating element, causing it to burn out in.
  • Corrosion: Corrosion on a heating element is not a serious problem at first, but can later cause small cracks which cause burn out.
  • System Strain: Setting your thermostat too high will make your furnace work excessively to achieve or maintain the desired temperature, causing the unit to prematurely burn out.
  • Wear and Tear: Finally, the heating element can burn out simply because of the usual wear and tear these components endure during their standard operating cycles.

How much does a heating element cost for a furnace?

The price of a furnace heating element can significantly vary. There are different factors contributing to the varying prices for a heating element, including the size of the furnace, the brand of the furnace, and the type of heating element required for that furnace.

Prices usually start at $100, but they can also cost $300 and more, depending on the aforementioned factors. It’s always best to consult a professional HVAC technician to acquire the adequate heating element for your furnace and replace it.

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

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.

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.
