LG LMAN120HNS Furnace Door Switch
A furnace door switch is a switch that stops the fan and other risky devices from activating in order to prevent injury and fire. It is quite important to have it substituted for a new part immediately if you can, if you suspect that it is not working.
How do you know if your switch on the furnace door is in need of replacing?
- The furnace will not engage whether the door is open or closed
- The safety door switch looks as if it has been broken badly
