Frigidaire FRS093LW11 Furnace Door Switch
The furnace door switch is a safety switch which prevents initial fan and ignition sequence from activating in order to prevent injury and fire. Do not try to fix it, just have it traded for new one immediately if you can, especially if you think it is defective.
Subtle cues of a dying safety switch on the furnace door
- The door mechanism is bent
- The whole system cannot run even when you close the door
