Whirlpool ATE1552SPP0 Furnace Door Switch
A furnace door switch is a switch that prevents initial fan and gas ignition from starting so as to stop a potential explosion. It is quite important to have it switched out ASAP if you suspect that it is not working.
What warnings should I watch out for to know if my switch on the furnace door is about to go out?
- The furnace does not fire up even with the door closed
- The door switch appears as though it has been chipped
