International Comfort Products PGMD60G0906 Furnace Door Switch
The furnace door switch is a safety switch which inhibits the fan and gas ignition from activating in order to prevent injury and fire. You should really have it changed as soon as you can if you see that it is broken.
What red flags are there that my switch on the furnace door is not working right?
- The HVAC system does not fire up with the door closed
- The switch seems worn down
