International Comfort Products PGC048L120F Furnace Door Switch
A furnace door switch is a safety feature that prevents initial fan and ignition sequence from activating so as to stop a potential explosion. Do not try to fix it, just have it changed swiftly if it is damaged so as to prevent something bad happening.
What to see if the safety door switch has a need to be replaced?
- The furnace does not fire up even with the door closed
- The switch appears to be fallen off
