My American Harvest 6039 ( its the older panel model)is having problems again. Burn pot was full again,so I turned off . When it fully turned off there was still smoke in stove. I opened it up and noticed the smoke was coming from the auger. My son said when he got home it was just about empty,so he went and got another bag and put it in. I pulled all the pellets out and at the bottom was some blackened pellets. I pulled the auger out and cleaned it completely. On start up I adjusted the combustion air with the "B" button and after that the panel went back to its normal setting,but it was an E 3. The feed auger usually runs every 5 sec for 5 sec. This time it waited a long time and ran for over 15-25 sec. So what is the E 3 ? I have been running Somersets for a couple of weeks and I would need to clean every 4 days. I just cleaned this past Saturday and put in Pro-Pellets and now it doing this. Maybe just a coincidence.
