We have a St. Croix Afton Bay about six years old. Lately it has been getting stuck in feed mode when put on setting 2 or 3. Last night I was woken up by the smell of burning paint it was so hot. The pellets just continually feed and I get a giant fire. We were very lucky last night. Not sure why it does this though. If I notice it doing it, I will change the feed rate back and forth and then it will stop feeding and goes back to a normal feed rate. Is this a bad board? The dealer we bought it from way back when has since gone out of business and wasn't much help then either. On another note I was told the blower motor needs oiling every six months amd it is very loud. Where do I oil it?
