Carrier 38HD Furnace Door Switch
The furnace door switch is a safety switch which prevents the draft inducer and ignition sequence from starting so as to avoid injuries. Do not try to fix it, just have it exchanged for a new one quickly especially if you think it is defective.
What are the signs that the safety furnace door switch is on its last leg?
- The door switch looks as if it has been fallen off
- The system will not engage even with the door closed
