Why Does My AC Trip the Circuit Breaker?


Has your air conditioner been tripping your circuit breaker? Are you worried about why it might be happening? This is a far more common problem than you might think, especially if you live in Pennsylvania. 

There are several reasons why your air conditioner might keep tripping its circuit breaker. If you are experiencing this problem, the best way to deal with it is to contact professionals for air conditioning repair in Newtown Square, PA, because they will know how to address this technical problem.

In this post, we will tell you why this might be happening so you can understand the importance of calling air conditioning experts immediately.

Reasons Your AC Is Tripping the Circuit Breaker

Here are some of the possible reasons your air conditioner is tripping the circuit breaker.

1. Clogged Air Filter

If your air conditioner is working with a clogged air filter, the unit must work much harder to circulate the air through the vents. Your AC will also need to run for longer to achieve the desired indoor temperature. Clogged and dirty air filters force your AC to draw more power to get the job done, causing it to draw more electricity and tripping the circuit breaker.

2. Shorted Blower Motor

The electric motors in your air conditioners may have to run for hours without rest, especially during the summers. Combined with issues like a clogged air filter, the blower motor in your air conditioner can heat up. This can result in your unit wearing down the insulation in the wires and cause a short-circuit that forces the circuit breaker to trip immediately to protect your home.

3. Dirty Condenser Coils

The condenser coils in your air conditioner’s external unit are responsible for absorbing the heat from the indoor air and transferring it outdoors so the AC can circulate cool air indoors. If the condenser coils become dirty, it can make it difficult for your AC to disperse the heat outdoors. Your air conditioner will need to work harder and for longer to keep your home cool, causing it to draw more electricity and trip the circuit breaker.

4. Broken Coil Fan

The external unit for your air conditioner is responsible for the heat exchange that cools down the air circulating inside your home. The coils rely on a fan that blows air over the coils to cool them down. If the fan in the external unit is not working properly or it has broken down, the condenser coils will have no means to cool down on time. Trying to run your air conditioner with a broken coil fan can lead to significant damage. You should immediately schedule expert help to repair the problem.

Your circuit breaker trips to protect the electrical appliances in your home from overcurrents. We recommend resetting your circuit breaker and turning it back on. If the breaker trips again, you need to call us for help to deal with the problem.
