Bottom auger stops turning and shut stove down. Thanks to other post I checked and reset the control panel. It was showing 'A' so set it to 'D' then 6-4-1 on bottom buttons.. Running on a 1 heat range and 2 on the blower we have plenty of heat. Fire seems high and not sure if its shuting down because of high temp. No codes are showing after shut down. Any thoughts?
