Goodman Gas Furnace - LED flashing "2" error code
Asked Nov 29, 2009, 01:26 PM
I have a 5 year old Goodman PGB024075-1A gas furnace. The LED is flashing a "2" error code, meaning an open end switch. I'm attempting to track down the potential causes of this error. After taking things apart, I found and removed an insect nest (the dirt clog kind) which had found its way into the inducer fan housing. It's all clean and the fan now spins freely. Unfortunately, same error. When I turn on the power at the service switch, with the thermostat set at AUTO/HEAT/80 deg, I can hear a click coming from the gas valve/inducer area, but then nothing. Any ideas on what to check/test next or what the problem may be? Thanks in advance for your help.
