Whirlpool ATR1243SPP0 Furnace Door Switch
The job of the furnace door switch stops the fan and ignitor from starting so as to avoid injuries. You should have the switch be traded for new one at once if you see that it is broken.
Major clues the switch on your furnace door is going to die
- The safety door switch looks like it is worn
- The whole system does not function whether the door is off or on
