My goodman air handle is run on e-heat only and will not turn off ,also the outside unit will not turn on , I put a new themostat this didn't help I have a goodman heatpump
Heat-Pumps can be temper mental. Sounds to me like your air handler is running on emergency heat, due to a problem with the condensing unit.You have heat strips in the air handler in case the outdoor temp. gets to cold and the heat pump cant keep you're home warm.Also, if you loose a compressor, it will go into emergency heat. If you have lost the compressor for one reason or another, lets say a locked rotor, the compressor would draw L.R.A. (Locked rotor amps) and cause the circuit breaker to trip. Check this.As for the air handler running all the time, you said you replaced the stat? When you removed the control wiring from the stat, did the fan shut off? I wish I were on site to help you, but all I can do is offer you some advice. With the power off to the air handler, go to the stat and remove the red and green wires. Turn power back on and see if it stops running. If it stops, then it sounds like the new stat is also faulty? If it continues to run, check the wiring in the air handler to make sure the red and green are not touching somewhere, and also check the control wiring on the outdoor unit for the same problem. Do you have any dogs that may have chewed into wiring? If so, check all outdoor t-stat wiring. There are so many things it could be and I hope very much I have helped you with solving this online, which can be difficult. You may also have a faulty defrost board. Try to do what I have asked of you.
Good Luck, Sincerely, shastalaker7
