Why Does My AC Keep Tripping the Circuit Breaker?

It’s the middle of a hot day, and suddenly the air conditioning system that’s keeping your home cooled down and pleasant shuts off. You go to the circuit breaker panel to check on it (something you should always do whenever a large appliance in your house stops working) and find that the breaker for the AC has tripped. You reset it, turn the AC back on… only to have the circuit breaker trip again not long afterwards. And it happens again and again.

Clearly, something is wrong with your air conditioner that’s causing the circuit breaker to keep tripping, but what? The best way to find out is to give HVAC professionals a call. They’ll look into the AC system and find out what malfunction is creating the problem. Below are some of the reasons this may be happening:

  • The circuit breaker itself is damaged: The problem actually may lie within the circuit breaker, not the air conditioner. You’ll need electricians to repair loose connections.
  • Shorted-out motor: The motors in an AC run the fans and the compressor, and they suffer from a great deal of wear and tear over a summer. If a motor overheats, the insulation on its wiring will melt, causing an electrical short. The circuit breaker detects the surge and trips so to prevent a fire. HVAC technicians will need to replace the motor.
  • Overworked compressor: No part of the air conditioner uses more electricity than the compressor when it turns on. If the compressor is malfunctioning because of age, it will draw so much electrical power that it can lead to a circuit breaker tripping. HVAC technicians can install a “hard start kit” that will give the compressor the extra electrical voltage it needs. (In some cases, you may need to have the compressor replaced.)
  • Grounded compressor: If the wiring in the compressor breaks, it will cause a direct electrical current to run to the ground. This will threaten to ignite the oil in the compressor and cause it to burnout. The circuit breaker will trip because of the surge from the grounding. In this case, you almost certainly need to have the compressor or even the whole AC replaced.
