Why is my air conditioner blowing fuses?

There are a number of different reasons why your AC may be tripping the circuit breaker or blowing the fuse. A knowledgeable professional should take a look at your unit to determine the exact cause and prevent a simple issue from turning into a complex problem that will require expensive major repairs. Here are some of the most frequently encountered culprits:

Clogged AC filters

Dirty filter issues are one of the most common reasons for AC failures. They can lead to a wide range of problems with your unit, including blown fuses. This is particularly the case during summer, when your air conditioner needs to work a bit harder in order to cool down the air in your home. In this situation, a dirty filter will put even more pressure on your AC, causing it to trip the circuit breaker or blow a fuse.

Capacitor failure

Your air conditioner has a capacitor, a component that regulates the flow of electricity into the condenser and compressor. If your AC capacitor has broken down, it may cause the air conditioner to blow fuses. You should have your capacitor tested or replaced if necessary by trustworthy AC professionals.

Loose wires

Loose wiring is another common culprit for blown AC fuses. Over time, the wiring that connects the different components of your air conditioner will expand and contract, becoming loose and affecting the performance and safety of your system. These high voltage circuits can be quite dangerous and should only be inspected by qualified professionals.

Condenser fan malfunctions

A faulty condenser fan will struggle to blow the air over your AC’s condenser coils, leading to decreased cooling efficiency. The extra pressure this places on your air conditioner can cause it to blow a fuse.

Refrigerant leaks

If your air conditioner is leaking refrigerant, your AC unit will have a harder time maintaining good performance. An air conditioner that keeps overworking itself will have a higher chance of tripping breakers and blowing fuses.

Regardless of the exact reason why your AC is blowing fuses, it is usually better to contact professionals if you notice suspicious behavior in your system. Many homeowners tend to ignore warning signs for too long, which often leads to major component failures that could have been avoided quite easily.

How do I know if my AC fuse is blown?

If you suspect that your air conditioner has blown a fuse, contacting professionals would be the best path to take in most circumstances. This is especially true if your air conditioner keeps malfunctioning in a similar way. A good way to check if your AC is blowing fuses is to inspect your outdoor unit. If it produces a low humming sound although it has no power, it is likely the case that the fuse has blown.

How long do air conditioner fuses last?

A typical air conditioner fuse is designed to last throughout the lifespan of your unit. Unfortunately, your air conditioner may experience a number of problems that may wear down the fuse over time. This is especially the case when air conditioners experience electrical issues. If you suspect that may be the case, reach out to your HVAC professionals of choice sooner rather than later to prevent further damage to your system.

How do I stop my air conditioner from blowing fuses?

Taking good care of your air conditioning system is the only surefire way to prevent electrical problems and keep your unit from blowing fuses. Here are some tips for maintaining the optimal performance of your cooling unit:

  • Replace your filters regularly: keeping your AC filters clean is a must if you want to ensure good performance. Make sure to check your filter at least once every three months and replace it if it is dirty or clogged.
  • Keep your outdoor unit clean: make sure to remove any debris, leaves, and dirt from your outdoor unit. It should be free from dust and obstructions in order to work efficiently, so make sure to inspect it regularly.
  • Inspect your breaker: if your AC has tripped the circuit breaker only once, you may be able to fix the problem by simply re-engaging it. However, if this isn’t the first time this has happened, contact professionals for AC repair as soon as you can.
  • Enroll in our maintenance plan: in general, proper maintenance is the best way to maximize the lifespan of your unit and prevent major repairs. A professional AC service will inspect all the components of your unit regularly and keep it running smoothly.
