The furnace door switch prevents initial fan and other risky devices from activating in order to prevent injury and fire. Do not try to fix it, just have it exchanged for a new one promptly if it is not working in order to prevent injuries.
What to see if the safety switch on the furnace door is about to stop working?
- The furnace door switch seems to be eroded
