International Comfort Products GPCM24K040F Furnace Door Switch
The furnace door switch is a safety switch which inhibits the blower and ignition sequence from switching on in order to prevent injury and fire. It is quite important to have it exchanged for a new one at once if you see that it is broken.
Indications the safety door switch should need replacing
- The HVAC system does not begin to work with the door closed
- The door switch seems bent
