Goodman GMH81155CN Furnace Door Switch
The furnace door switch is a safety switch which inhibits the draft inducer and ignition sequence from starting in order to prevent injury and fire. You should really have it exchanged for a new one quickly if it is damaged so as to prevent something bad happening.
Subtle cues of a barely functioning safety switch on the furnace door
- The door switch seems bent
- The HVAC system does not fire up with the door closed
