I have 3 breakers for the heat pump/AC. 1 in the main panel. 1 in the main unit closet that I thought was only for the heat. Finally 1, at the outside unit.
The one in the main unit closet heats and eventually trips when on heat pump only. I can swith to the aux coils (standard heating coils) and the breaker gets warm but does not trip. The main breaker in the circuit box and the outside breaker at the comp/evap do not get warm and do not trip.
BotXXXXX XXXXXne: no heat pump and no AC. The compressor does not kick in at all. I do not see how this causes a breaker trip on the heat pump side.
To be clear to you, I am not an AC guy. I am an electrical engineer. It seems to be an electrical problem to me. But, let's face it, other than basic theory on how AC/heat pumps work and putting guages on the freon, I'm just another Harry Homerowner. It seems to be some electrical connection between the two problems..........but, I have to recognize I'm just Harry Homeowner.
It seems odd to me that you have 3 breakers to the HP. 2 is normal but the one in the closet is kinda weird....
Check on the data plate what the maximum amp breaker is and then check what amp breakers you have in the house for starters...maybe we just have an undersized breaker
