Carrier 50JX036300 Furnace Door Switch
A furnace door switch is a switch that prevents the fan and other risky devices from switching on in order to prevent injury and fire. You should really have it traded for new one as soon as possible if it is defective in some way or another.
What warnings are present when my furnace door switch is almost dead?
- The whole system will not fire up even when you close the door
- The furnace door switch looks like it is breaking apart
