My auger On my 5 series vertical stops after about a minute after powering on. The auger motor shuts down so it’s not just sticking or binding. But when I hold prime button down, auger works fine. Disassembled auger and motor, cleaned both auger and auger shaft (some rust/pitting on auger), cleaned hopper and hopper feed. Reassembled all and got same result. Switched wires from auger motor to combustion fan and auger ran perfectly fine but the combustion fan shut down after a minute. Is this a control board issue? Should I just replace entire control board or is there an easier, simpler fix?
