Goodman ARUF496116CA Furnace Door Switch
A furnace door switch is a switch that stops initial fan and ignition sequence from switching on so as to stop a potential explosion. You should really have it replaced promptly if it is not working in order to prevent injuries.
Symptoms of an ineffective safety door switch
- The furnace will not start whether the door is open or closed
- The safety door switch looks as if it has been bent badly
