Hello everyone. New to the forum. My dad was given a used American Harvest 6039 under the assumption that it needed a new board. It was the old ABC button type and was replaced with the newer type, as it was described as the replacement part. I figured it must be just an improved design or something. We can't get the auger to feed fast enough to keep the fire going. It just runs about a quarter turn about every 25 or 30 seconds. We have to throw a handful or two of pellets in the pot about every ten or fifteen minutes. I've tried holding the heat range and aux buttons down to change the feed rate and it didn't change anything. It's on 6 1/2 pph and it's still running just like it was. I took the thing apart and cleaned it out inside as per a thread I read on here thinking that might be it, but it made no difference. We're both baffled. If it tells you anything, the little red light next to the "draft fan up" button flashes. I don't know what else to try. You guys seem pretty knowledgeable, so hopefully one of you might have the answer. Thanks!
