Lennox HP13-018 Furnace Door Switch
A furnace door switch is a safety feature that stops the fan and other risky devices from starting so as to stop a potential explosion. Do not try to fix it, just have it substituted for a new part as soon as you can especially if you think it is defective.
Signs the safety door switch will need to be replaced
- The door mechanism looks like it is not there
- The HVAC system will not engage whether the door is open or closed
