Goodman GSH140301A Furnace Door Switch
The furnace door switch is a safety switch which blocks the vent fan and burner from starting in order to prevent injury and fire. Do not waste time and have it substituted for a new part ASAP if you see that it is broken.
How do you know if your safety furnace door switch is dying?
- The furnace will not even begin to start even with the door closed
- The switch has been bent badly
