International Comfort Products T9MPV125L20B1 Furnace Door Switch
This switch prevents the vent fan and burner being triggered to start so as to avoid injuries. Do not try to fix it, just have it switched out as soon as possible especially if you suspect it is not working properly.
What signals that my switch on the furnace door is about to go out?
- The whole system does not run with the door closed
- The furnace door switch looks beat up
