Heat Exchanger blows circuit breaker

[becki_jo71]

I noticed that the heat exchanger (outside unit) wasn't working. It turns out that it had blown the circuit breaker at the main breaker box.
Every time that I reset the breaker it blows again within seconds. I have tried turning everything off then resetting it and then slowly adding the components but to no avail. Everytime the heat exchanger comes on the circuit breaker blows. Can anyone tell me what may be causing this?

more than likely caused by 1 or 2 scenerios. Either or condesor fan motor or your compressor has shorted to ground. If it is the compressor, depending on the age of the unit you should consider replacing whole unit as compressor changes can be very expensive.
