I finally got my used Harmon Accentra insert installed. Bought if from a guy who just had a combustion blower put in it. Date inside unit is Sept. 2006. Install went well, pulled my 4" stainless liner, and I cleaned it real good while I had it outside. It had no soot what so ever anywhere. Loaded it with pellets and fired it up. I loved it. I burnt it for 5 hours. Here is my question and issue. I turned the dial to off to shut it down. The auger motor still ran slightly for another 20 minutes dropping pellets. After about 20 minutes it finally stopped and the fire went out (is this normal?). I wanted to watch the entire stove shut down. The indoor fan and combustion blower kept running.....The indoor fan shut down but the combustion blower kept running. I figured once it cooled down the combustion blower would shut down, so I went to bed. When I got up, this morning, the combustion motor is STILL running. The light on the board is still lit calling for it to run. I unplugged it then plugged it back in and the light went out and the blower stopped. I never had a pellet stove before but I do HVAC for a living. BUT I know you guys are experts so I am asking here. My guess is the ESP sensor by the combustion fan or the board, but I do not want to go parts changing because I am sure parts are not cheap. Any help/advice is greatly appreciated
