Carrier 50XP030300 Furnace Door Switch
A furnace door switch is a safety feature that prevents initial fan and gas ignition from switching on in order to prevent injury and fire. It is extremely important that the device is changed at once if it is defective in some way or another.
What are some indications that my safety switch on the furnace door is almost going bad?
- The door mechanism seems to be removed
- The furnace will not run even when you close the door
