International Comfort Products PGC048H080F Furnace Door Switch
The furnace door switch stops the fan and burner from activating so as to stop a potential explosion. It is quite important to have it substituted for a new part immediately if you can, if you find it to be faulty.
What warnings should I watch out for to know if my furnace door switch is not working right?
- The safety door switch looks as if it has been worn down
- The furnace does not operate whether the door is off or on
