HELP!! This happened once before where the stove ran out, and when I refilled and started I noticed it didn't start. Then tried restarting again and still no start. Then third time I became suspicious and the auger was rotating backwards - not pushing the pellets into the burn pot. I have had this once before and I can't recall what I did to reverse this. If there is a consistent procedure can someone let me know please!! Its getting cold in here....
