Samsung AVMBC040CA0 Furnace Door Switch
The furnace door switch is a safety switch which prevents the vent fan and gas ignition from switching on so as to stop a potential explosion. Do not waste time and have it swapped out promptly if you see that it is broken.
Signs the switch on your furnace door is in dire straights
- The safety door switch looks as if it has been worn down
- The HVAC system will not engage even with the door closed
