International Comfort Products GPCM36L080F Furnace Door Switch
The furnace door switch is a safety switch which blocks the blower and ignition sequence from switching on in order to prevent injury and fire. You should really have it substituted for a new part immediately if you can, if you suspect that it is not working.
What are the indications that my safety switch on the furnace door is about to go out?
- The HVAC system will not run with the door closed
- The door mechanism seems to be bent badly
