Goodman GME80704BX Furnace Door Switch
The furnace door switch blocks the vent fan and other risky devices being triggered to start so as to stop a potential explosion. Do not try to fix it, just have it switched out as soon as possible if it is not working in order to prevent injuries.
Red flags the switch on your furnace door needs replacing
