A furnace door switch is a safety feature that stops the fan and gas ignition from starting so as to avoid injuries. You must have the device exchanged for a new one as quick as you can if you suspect that it is not working.
Key clues of a dying switch on the furnace door
- The system will not operate whether the door is open or closed
- The door mechanism appears as though it has been removed
