Carrier 50JZ Furnace Door Switch
The job of the furnace door switch stops the draft inducer and burner from switching on in order to prevent injury and fire. Do not try to fix it, just have it exchanged for a new one promptly if it is defective in some way or another.
Indications the switch on your furnace door needs replacing ASAP
- The door mechanism seems breaking off
- The HVAC system does not run whether the door is open or closed
