International Comfort Products HHP024AKA1 Furnace Door Switch
The job of the furnace door switch blocks the vent fan and other risky devices from switching on in order to prevent injury and fire. You should have the switch be traded for new one as quick as you can especially if you think it is defective.

- The switch appears as though it has been bent
- The HVAC system will not engage whether the door is open or closed
