Carrier 38EYA030 Furnace Door Switch
A furnace door switch is a switch that blocks the draft inducer and gas ignition from switching on in order to prevent injury and fire. You should really have it exchanged for a new one promptly if it is damaged so as to prevent something bad happening.
Major symptoms of a weakening safety switch on the furnace door
- The door mechanism appears as though it has been broken
- The whole system cannot run whether the door is open or closed
