Carrier 58MVP080F15120 Furnace Door Switch
A furnace door switch is a safety feature that blocks the draft inducer and burner from activating in order to prevent injury and fire. Do not try to fix it, just have it changed at once if it is causing you problems.
Clues the switch on your furnace door should need replacing
- The safety door switch looks as if it has been wrong
- The HVAC system does not fire up even with the door closed
