Amana Heat Pump Tripping Breaker

\015 I have an Amana Heat pump system. It is about 6 or 7 years old. It was working just fine until a few days ago.Now, it trips the double breaker in my electrical panel when it tries to come on.....Immediately trips it.I pulled the outside breaker next to the pump and then turned the breaker back on in the electrical panel in the house and it didn't trip. So, I am figuring the wiring from the sub panel to the main panel is all okay.Which leaves me with a problem from the sub panel to (and/or) through the heat pump.Does anyone have a place I can start diagnosing the problem....I have already exposed the electrical *guts* on the pump, where all the connections and circuit boards are located.TIA for any help you can provide!BillPS I think the size of the heat pump is a 3.5 ton?\015

Answers :

My guess I would say, you either have a wire that is short to ground or if the contacter pulls in, then I would say the compresser is short to ground.There also could be some capacitors that could be short.

Amana #PTC153b50AJ ser 0410686783 Customer heard a pop in unit and it went off. Breaker was tripped. Reset breaker and unit runs in a/c mode but does not heat in heat mode. This is not a heat pump but electric heat strips. Unit says there is a manual reset for the heat but we have not located the reset. We turned power off to the unit to reset fault etc and still no heat. The flashing light just blinks once every 4-5 sec. Could use some help in diagnosis Thanks DK

Goodman heat pump model CPKJ421B. Tripped breaker for outside unit two weeks ago. Reset breaker, tripped again today. Unit won't run now. Did some basic checks and found that the 28 vac from the inside unit was not going through the low pressure switch to pull in the 220 vac contacter for the compressor. Possibly either the refrigerant is low or the low pressure switch is bad. Could a faulty switch, maybe losing and regaining contact quickly, trip the breaker? Could the refrigerant, just before

I have an Amana RHE30A2B heat pump. I installed a new thermostat, Honeywell, last night and now the coils are not cooling & the unit is blowing hot air.
