Question about Air Conditioners
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
GOODMAN HAS A PROBLEM WITH A FAULTY REVERSING VALVE. THEY IMPORT VALVE FROM CHINA AND ITS NOT GOOD QUALITY, THEY ARE IN PROCESS OF CHANGING VENDOR.

AVOID GOODMAN AT ALL COSTS, I have a SSZ14 with a bad reversing valve. Not to mention the shoddy construction of the sheet metal, etc.

Sounds like it's in the thermostat wires. I would change the low voltatge wiring.
