International Comfort Products N9MP1080F16C2 Furnace Door Switch
A furnace door switch is a switch that inhibits initial fan and ignitor from turning on so as to stop a potential explosion. Do not try to fix it, just have it switched out promptly if it is defective in some way or another.
Major red flags the safety door switch should need replacing
- The door switch seems bent badly
- The system does not even thing about starting even when you close the door
