The furnace door switch is a safety switch which blocks initial fan and other risky devices from turning on so as to stop a potential explosion. Do not try to fix it, just have it substituted for a new part as soon as possible if it is damaged so as to prevent something bad happening.
Clues the safety door switch is going out
- The door switch looks as if it has been bent
- The furnace will not even begin to start whether the door is off or on
