Carrier 24ABR342G0030010 Furnace Door Switch
The furnace door switch is a safety switch which blocks the blower and other risky devices being triggered to start in order to prevent injury and fire. Do not try to fix it, just have it substituted for a new part promptly if you see that it is broken.
Elements of a laboring safety furnace door switch
- The HVAC system does not operate whether the door is open or closed
- The door mechanism looks as if it has been broken badly
