Carrier 58STA11010016 Furnace Door Switch
The job of the furnace door switch prevents the draft inducer and burner from turning on so as to stop a potential explosion. Do not try to fix it, just have it replaced quickly if it is defective in some way or another.
What happens when my safety furnace door switch is not working properly?
- The system will not engage even with the door closed
- The safety door switch looks as if it has been chipped
