Carrier 58DLA09010016 Furnace Door Switch
A furnace door switch is a safety feature that blocks the vent fan and burner from activating so as to stop a potential explosion. You must have the device changed as soon as you can if you see that it is broken.
What warnings are present when my switch on the furnace door is not working properly?
- The system will not engage whether the door is off or on
- The door switch looks as if it has been broken
