Carrier 58MVB040F10114 Furnace Door Switch
A furnace door switch is a switch that stops initial fan and gas ignition from switching on in order to prevent injury and fire. It is quite important to have it traded for new one promptly if it is causing you problems.
What red flags are there that my safety furnace door switch is crapping out?
- The HVAC system does not turn on with the door closed
- The door mechanism appears as though it has been fallen off
