The furnace door switch is a safety switch which prevents the blower and gas ignition from starting in order to prevent injury and fire. It is extremely important that the device is substituted for a new part at once if it is not working in order to prevent injuries.
Signs the safety door switch has to be replaced
- The door mechanism appears as though it has been broken
- The system does not run whether the door is open or closed
