I just purchased a goodman 4 ton 15 seer heatpump... it has been installed and is being a pain. It was not heating properly and we have isolated the problem down to the reversing valve. It stays engerized all the time. My installer is telling me the unit is defective. He substituted a different thermostat- same result. For the short term he just disconnected the wire to the reversing valve and it is working well now.
My question is what other troubleshooting can we do to figure out why the reversing valve stays enegized? Is this a failure in a circuit board somewhere or is it possible that there is a wiring problem or a thermostat programming problem as I suspect?
My installer brought a manual thermostat and the unit still did same- try to run the a/c and the heat strips simutaneously.... He disconnected the wire that energised the reversing valve and it works fine now... So where do I start to confirm that the unit is bad versus a self induced problem?-rob
Installed a Goodman GPH1548 Dec 2007. Reversing value would hang up part or all the way after defrost mode. Controll board was de-engizing the reversing value (replaced anyway). Replaced reversing value, problem returned in less than two weeks. Found exspansion value bad, replaced same. Problem returned in two weeks, in addition to the reversing value not switching found one stage of compressor not working. Replaced entire GPH1548, less than two weeks reversing value hanging up in new unit (Heat pump mode plus heat strips supply air was 58 degrees return air was 60 degrees, supply air is 85-97 when reversing value closes completely)
Air conditioning working great.
Any ideas that do not include replacing the reversing value or other parts that require the removeing and replaceing the R410?Installed a Goodman GPH1548 Dec 2007.

Check contactor that operates compressor and condenser fan. Does it try to come on when you first turn it on, or just sits there? If it tries to come on, it could be the capacitor.
Put meter probes at in put terminal of the element if you read 220volts that mean your relay is good. if you got it there use amp meter on one leg of that element. You should read some amp draw there but if there is no amp draw it mean the element broke.
I install them every day and I have not had one make a loud grumbling sound. Sounds like you might have a low voltage (Thermostat) wiring problem. The only thing different inside the indoors unit from heat and cool is the fan speed, electric heat when on. The fan might be loose or out of balance and it only shows up at low speeds. Either way, the noise is not normal.
That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up! The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.
Does it make the noise all of the time or just periodically? Does the outdoor fan run when it is making the noise. If the fan isn't running and the compressor is noisy at that time likely it is in defrost mode which is normal.
