International Comfort Products T2A330GKA100 Furnace Door Switch
The job of the furnace door switch inhibits the draft inducer and other risky devices from starting so as to avoid injuries. Do not waste time and have it swapped out as soon as you can especially if you think it is defective.
Major signs the safety door switch is on its last leg
- The door mechanism looks as if it has been stuck
- The furnace will not engage with the door closed
