Hi There, A couple of days ago I came downstairs and found that the stove had gone out. I knew I had pellets in the hopper so I was not sure what was up. After taking the pellets out of the hopper I found the top auger was working, but the lower was not. I have the 2200 sq foot version and replaced the auger once already about a year ago. I would think that it should last over a few months since it obviously was not used during the summer months. Is there anything else I should look at as the culprit before I unhook from the wall(corner insall, hard to work back there). Maybe the vaccum switch or something?? Any advise would be greatly appreciated!
