Goodman P1256802F Furnace Door Switch
The furnace door switch is a safety switch which inhibits the fan and burner being triggered to start so as to stop a potential explosion. Do not waste time and have it substituted for a new part immediately if you can, if it is causing you problems.
Chief elements of a weakening safety door switch
- The door mechanism looks broken completely
- The HVAC system does not fire up even with the door closed
