International Comfort Products NTC5075BFC1 Furnace Door Switch
The job of the furnace door switch stops initial fan and burner being triggered to start so as to stop a potential explosion. Do not waste time and have it switched out as quick as you can if it is not working in order to prevent injuries.
How do you know when your switch on the furnace door is dying?
- The system does not function whether the door is open or closed
- The safety door switch looks like it is broken completely
