I have a Harman Accentra insert that was bought in 2010. I just changed the auger motor last weekend and pulled the auger out and cleaned it. The bearings of the auger seemed to be good. Stove was working fine throughout the week, but has stopped once again. Could a faulty combustion or distribution blower prevent the auger from turning? Is there something else that could prevent the auger from feeding pellets? Thank you for your input.
