Samsung AVMWH072CA0 Furnace Door Switch
A furnace door switch is a switch that blocks the blower and other risky devices being triggered to start so as to stop a potential explosion. Do not try to fix it, just have it changed immediately if you can, if it is defective.
How do you know when your safety door switch has a need to be replaced?
- The door mechanism looks like it is eroded
- The furnace cannot run even when you close the door
