LG ARNU093TJC2 Furnace Door Switch
The furnace door switch stops the fan and gas ignition from activating so as to avoid injuries. It is quite important to have it traded for new one as soon as possible if it is causing you problems.
Signs your furnace door switch will have to be replaced

- The whole system will not operate with the door closed
