Friedrich MW24C3G Furnace Door Switch
The furnace door switch is a safety switch which inhibits the blower and burner from activating in order to prevent injury and fire. It is crucial to have this part switched out at once if it is damaged so as to prevent something bad happening.
What are the clues to watch out for to know my safety switch on the furnace door has to be replaced?
- The system cannot run even with the door closed
- The door switch appears as though it has been bent badly
