Samsung UPC3240C Furnace Door Switch
The furnace door switch prevents the fan and other risky devices from switching on in order to prevent injury and fire. You must have the device changed as soon as you can if you find it to be faulty.
What warnings are present when my furnace door switch is on its last leg?
- The HVAC system does not even thing about starting even with the door closed
- The door mechanism seems damaged
