Goodman GDH81155CX Furnace Door Switch
A furnace door switch is a safety feature that stops the fan and burner being triggered to start so as to avoid injuries. Do not waste time and have it exchanged for a new one as quick as you can especially if you think it is defective.
Symptoms your furnace door switch is on its last leg
- The system does not even thing about starting whether the door is off or on
- The door mechanism is messed up
