I have an American Harvester Multi-fuel wood\corn pellet stove. I burn only wood pellets. About a month ago I had to replace my auger motor. With the new motor the pellets feed at a high rate of speed causing the ash pan to fill quicker than the pellets can burn. I have it currently set at 3 heat, 9 room fan, 2 draft fan, and 1 auger. I have the draft in the front out about 1 1\2 inch. The pan is still filling up causing the glass to go black. Please any advise would be appreciated. This is model 6039 stove.
