Carrier 48HJE008 Furnace Door Switch
A furnace door switch is a safety feature that prevents the draft inducer and ignition sequence from turning on so as to stop a potential explosion. It is extremely important that the device is traded for new one as soon as possible especially if you suspect it is not working properly.
How do you know if your safety door switch is almost dead?
- The furnace does not run even when you close the door
- The switch seems bent
