Mitsubishi MSZ-A17NA Furnace Door Switch
A furnace door switch is a safety feature that prevents the fan and gas ignition being triggered to start in order to prevent injury and fire. Do not waste time and have it changed as quick as you can if it is defective in some way or another.
Indications the safety door switch is on its last leg
- The furnace will not operate whether the door is open or closed
- The door switch looks broken completely
