LG ARNU123SER2 Furnace Door Switch
A furnace door switch is a switch that blocks the draft inducer and ignitor from switching on in order to prevent injury and fire. It is extremely important that the device is traded for new one quickly if it is defective.
How do you know when your switch on the furnace door is in need of replacing?
- The furnace will not even begin to start with the door closed
- The safety door switch appears to be broken
