Goodman GMV951155DX Furnace Door Switch
A furnace door switch is a safety feature that blocks initial fan and ignition sequence from starting so as to avoid injuries. It is extremely important that the device is replaced ASAP especially if you suspect it is not working properly.
Indications of a declining safety door switch
- The furnace does not begin to work even with the door closed
- The door switch appears as though it has been beat up
