The furnace door switch blocks initial fan and gas ignition from switching on so as to avoid injuries. Do not try to fix it, just have it substituted for a new part ASAP if it is defective in some way or another.
Major clues of a poorly working safety switch on the furnace door
- The whole system does not fire up even when you close the door
- The door mechanism is stuck
