Carrier 58STA07010008 Furnace Door Switch
A furnace door switch is a safety feature that stops the vent fan and ignitor from turning on so as to avoid injuries. You should have the switch be switched out as quick as you can if you see that it is broken.
What happens when my furnace door switch is crapping out?
- The HVAC system will not start even when you close the door
- The door mechanism looks removed
