Carrier 38YD Furnace Door Switch
A furnace door switch is a switch that prevents the draft inducer and ignition sequence from activating in order to prevent injury and fire. You should have the switch be substituted for a new part at once especially if you suspect it is not working properly.
What red flags are there that my safety furnace door switch has a need to be replaced?
- The HVAC system does not even thing about starting with the door closed
- The switch seems to be worn down
