Why Does My Air Conditioner Keep Blowing Fuses?

Never Worry About Your AC Tripping a Breaker or Blowing Fuses Again

One of the most aggravating — and rather common — issues with cooling systems involves the air conditioner tripping the breaker or blowing a fuse in the circuit board when it cycles on.

Repeatedly running to the fuse box and changing the fuse is cumbersome, time-consuming, and a sign of a greater problem with your cooling system or your electrical circuits.

You don’t want to fool around with this type of problem. When it comes to HVAC electrical problems, you want a skilled HVAC technician and electrician.

Common Reasons Your AC Keeps Blowing Fuses in Your Circuit Board

There are several reasons why your air conditioning system keeps blowing a fuse. Some of the most common problems are:

  • Dirty air filters: High temperatures in the summer can make it more difficult for your AC to push cool air through a dirty HVAC filter. This can put extra pressure on the system and blow the fuse. A dirty condenser coil can sometimes have a similar effect. It’s best to schedule AC maintenance in spring to avoid such problems.
  • Low refrigerant: If the refrigerant is low, your AC has to work harder. This extra effort sometimes causes a trip in your system. If the refrigerant is low, you could have a leak, which can be dangerous. If you think this is the case, you should call for AC repair quickly.
  • A problem with your fuse box, circuit, or central power supply: The most logical cause is a problem with the circuit that powers the AC. Breakers and fuses are designed to trip or blow when too much voltage is sent through the line. Simply inserting a larger fuse is a recipe for disaster. You need a licensed electrician to get to the root of the problem to prevent any electrical overloads.
  • An issue with your cooling system’s capacitor: The capacitor is a part of the cooling system’s condenser. This small part helps regulate the electrical current flowing through the condenser. A problem with this easy-to-replace part is another reason for blown AC fuses.

Whether you have any of the above issues, or your Maryland or DC air conditioner is tripping breakers for any other reason, contact Michael Bonsby for superior AC repair and circuit breaker upgrades.

Can I Fix a Blown AC Fuse or AC-Related Breaker Trip Myself?

Electrical issues should be handled by a professional for safety reasons. Still, there are steps you can take to troubleshoot an air conditioner that keeps tripping a circuit breaker:

  1. Replace your air filter: An airflow restriction caused by a clogged air filter will make your AC struggle, which often leads to overheating and potential breaker trips. If your air filter is visibly dirty or hasn’t been changed in a while, do it now.
  2. Clean all supply & return vents: Keeping your air vents free of dust and debris is important for the same reasons stated above. You should also be sure that no furniture, carpets, or window curtains are blocking vents.
  3. Check your outdoor unit: The fins surrounding your outdoor unit can also get clogged, usually with grass clippings and leaves. Clean these away using a firm brush, and straighten any bent fins with a slim tool.
  4. Reset your breaker: Once all the above tasks are done, reset your breaker (or swap your fuse if your electrical system is older). If one of the listed potential causes was to blame, your AC should run fine from now on.
