Hello, Usually, it would be a grounded compressor that can cause a unit to trip a house hold circuit breaker but who knows if it is really the compressor unless you remove the compressor from the circuit.

You can do that by un plugging the unit first, then look at the side of the compressor where the wires are attached, remove the all the wires but remember where you took them because you would return it in case it is not the compressor.

Now, once the wires are removed, taped all the ends with an electric tape, then plug the unit.

If the unit would no longer trip the house hold circuit breaker, then you have proven that it is the compressor was the one making it trip.

And sorry to tell that is it not a simple fix. You would have to call an engineer to replace the compressor and get a quotation first because it is a little bit expensive to replace one.

Oh. And so , what was found out on the unit? Was it a faulty compressor?

Oh. It could be more economical to just replace the unit because of the major issues it got right now. Specially if it is really the compressor. It is the most expensive part of the unit. As well as the cost of replacing it. Thank you very much for using Just Answer.
