Lennox G24-200 Furnace Door Switch
A furnace door switch is a switch that blocks initial fan and gas ignition from starting so as to stop a potential explosion. You must have the device traded for new one promptly especially if you suspect it is not working properly.
What warnings are present when my switch on the furnace door really needs to be replaced?
- The door mechanism appears as though it has been beat up
- The system will not fire up even with the door closed
