LG LP155CED1 Furnace Door Switch
The furnace door switch prevents the draft inducer and ignitor being triggered to start in order to prevent injury and fire. It is imperative that the switch be traded for new one immediately if you can, if it is causing you problems.
Important clues of a barely functioning switch on the furnace door
- The door mechanism looks chipped
- The system does not run whether the door is open or closed
