International Comfort Products T9MPT125L20A1 Furnace Door Switch
A furnace door switch is a switch that prevents the blower and other risky devices from switching on in order to prevent injury and fire. You should really have it switched out at once if you find it to be faulty.
Major clues the safety door switch needs replacing
- The furnace does not even thing about starting whether the door is open or closed
- The safety door switch appears as though it has been bent
