Circuit breaker keeps tripping:

Resetting a circuit breaker


If the circuit breaker to your indoor or outdoor unit trips, you may reset it. Turn it to the "off" position if it isn't there already, then back to the "on" position. If the breaker trips a second time, then you should schedule a service call.

The breaker is tripping for a reason. It is protecting the equipment, the wiring, and the house. Do not just keep resetting it and ignoring the situation. Yes, it is possible that maybe it is just a bad breaker or maybe it was just a thunderstorm. But you are dealing with high voltage and amperage, and possibly high temperatures, which could cause wires to melt, possibly starting a fire.

Loose Electrical Connections...

One very common cause for breakers to trip is loose electrical connections. Larger aluminum wires especially, tend to expand and contract with the weather, causing the connections to loosen over time. It is just a matter of tightening the connections. * Use extreme caution, High Voltage!

Another common cause is a direct electrical short in the wiring or equipment. This is identified by the breaker tripping instantly, once the unit attempts to start. In this situation, do not even try to reset the breaker again. Call for service immediately.

Sometimes the breaker for the outdoor unit trips because the compressor is having trouble starting. The compressor could be old, weak or just tight and a "hard start kit" (installed by a service technician) might do the job getting it going again. Or it may be as simple as replacing a bad capacitor which helps start the compressor.

Below is a list of possible causes. Items in red usually require a service call. Items in blue however can be addressed, some even fixed by the homeowner.

Red = Professional fix | Blue = Homeowner fix

  • Shorted component or wiring
  • Locked-up motor or compressor
  • Weak or ruptured capacitor
  • Loose electrical connection
  • Loose breaker
  • Bad breaker
  • Over-amping due to a mechanical problem
  • Under-sized breaker or wire
  • Weak compressor
  • Low voltage to the house, brown-out
  • Severe thunderstorm

The bottom causes in blue are commonly found problems and can be addressed by the homeowner. Try to check for these conditions first before calling for service.

Note - A circuit breaker should never feel hot to the touch. You can touch the breaker by using the backs of your fingers. The breaker should feel room temperature or warm. If it is hot, this could indicate a problem. Do not ignore it!
