International Comfort Products TCH036AKA1 Furnace Door Switch
The furnace door switch blocks the blower and gas ignition from activating in order to prevent injury and fire. Do not waste time and have it swapped out as soon as you can if you suspect that it is not working.
What signals that my switch on the furnace door really needs to be replaced?
- The furnace door switch looks bent
- The furnace will not operate even when you close the door
