A heat pump has a reversing valve to send the hot gas to the inside when you want heat. It sounds like the reversing valve solenoid might have been been damage from the loss of electric, or its possible to it could be nothing more than a bad thermostat. I would have to say in this case that you would be far ahead to call a service company to give you a estimate on the repair. This is most definitely not a handyman or do it yourself repair. It does involve working with live electric circuits.
is green wire from thermostat or from outdoor. retrace and change as needed. If not Goodman has a tech support number you can call while looking at unit.
Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus
The reversing valve may be stuck or it has a burnt solenoid coil. Also, check the defrost relay accross the contacts with an ohmmeter and see if it's bad. Goodman heat pumps also trip on high pressure. There's a resettable switch on some units with a red button. However, I think the problem is in the defrost circuit or reversing valve. If your electric heat is on, change the board.
Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
Good luck.
I already found that the it's heat pump. Thank you any way.
I don't understand your question.
