I’ll have to try and rig up a wire to jump the two thermostat wires and see what happens. Pretty sure it’s not the hopper lid hitting the switch. Tried lifting up on the lid when opening and it was still in manual. Also tried opening and closing in auto mode and it was still on auto (switch pushed up) when I opened. Also no visible wear on the switch from rubbing. Will try jumping the thermostat and let you know.
