Carrier 50TFQ008 Furnace Door Switch
The furnace door switch blocks initial fan and ignitor being triggered to start so as to avoid injuries. You should really have it exchanged for a new one as quick as you can if it is defective in some way or another.
Major indications the switch on your furnace door has little life left
- The safety door switch seems to be broken completely
- The whole system will not fire up even with the door closed
