International Comfort Products GPFM36L100F Furnace Door Switch
The furnace door switch is a safety switch which prevents the blower and ignition sequence from activating so as to stop a potential explosion. Do not try to fix it, just have it changed immediately if you can, if it is causing you problems.
Key symptoms of a poorly working safety door switch
- The HVAC system will not engage with the door closed
- The door mechanism is broken badly
