Whirlpool ATR0742RPP0 Furnace Door Switch
The furnace door switch blocks the vent fan and ignitor from turning on so as to stop a potential explosion. Do not waste time and have it traded for new one promptly if it is damaged so as to prevent something bad happening.
Signals of a weak switch on the furnace door
- The furnace does not fire up whether the door is off or on
- The door mechanism looks like it is broken badly
