LG LP090HED1 Furnace Door Switch
This switch inhibits the vent fan and ignitor from turning on so as to avoid injuries. Do not waste time and have it switched out promptly if you suspect that it is not working.
How do you know when your switch on the furnace door is not working properly?
- The system does not even thing about starting whether the door is open or closed
- The furnace door switch is worn down
