You can always just cut and solder the wires together or use a butt splice to make it think the door is always closed. The lid switch for the actual bbq on mine broke as well so no big deal opening the lid with the fan on. Note of caution if this is for the hopper lid or ash tray door i would move the switch from the big lid into the broken spot. If you open the hopper or ash door with the fan on at a high temp that could be a recipe for disaster
