I have a Goodman MFG ARUF061-00A-1B Airhandler with the optional HKR-20C Heat Strips installed in new construction, 2ksf home.
When running the T-stat in Emergency mode, to activate the heat strips (trying to heat up the house from outside cold temps), the unit will start operation, produce heat, and run for a few hours. When I come back to check on things hours later, the unit has shut down, and I find that one of the factory installed 60amp breakers that are incorporated into the heat strip unit has tripped.
When running the unit in Heat mode (running the heat pump function), it will operate constantly without interruption. The problem is, that with the cold temps, the unit is taking forever to heat the house. (4 degrees F in 12 hours overnight)
The electrician is going to check his work tomorrow, but the HVAC installer feels that it is not a problem with the unit - he believes that the unit is not getting enough power, causing the breaker to trip. I know little about electricity, but this doesn't make sense to me. Also, there are matching 60amp breakers at the electrical panel, which are not tripping.
Am I wrong - is a lack of power the possible culprit? Any other ideas to check out would be greatly appreciated!
