The furnace door switch is a safety switch which inhibits initial fan and ignition sequence from activating so as to stop a potential explosion. It is important to get the part exchanged for a new one promptly especially if you suspect it is not working properly.
What red flags are there that my safety door switch has to be replaced?
- The door mechanism seems bent
- The HVAC system does not fire up even when you close the door
