    I went to shut down the stove to fix an auger squeal but even in the off position the auger kept turning. It slowed to a maintance burn and the dist. blower kept going. The stove was REALLY cranking at the time. Does Harman use the ESP to cool the stove down before coming to a complete stop? It would make sence to do this and eliminate the chance of fire backing up in the auger. It's never done this before but I've never shut it down on max fire before. I didn't let it run it see if it would have ever stopped just opened the door and pushed the stir rod back (to fix this squeal) now I'm curious. Room temp auto if it matters.

    Never shut mine down from full throttle but I suspect the fact the auger was still feeding was due to the CB ramping down the burn. If it didn't do that, the residual heat from the remaining pellets would burn into the auger tube a little farther than what Harman considers safe. Does that make sense?.....ohh..my head! ;)

    What you describe sounds normal to me especially since you had in cranking. The ESP does control the shutdown procedure. Having said all of that I would force it to do it again when you have the patience to see if it shuts down on its own.

    The stove can take 45 minutes to an hour sometimes to totally shut off.

    Thank you gents. It seems the stove is not controling as evenly as normal but the residual heat has got to be the problem, that stove is cranking, even got the water pot on top simmering. I think I'll make soup.

    clean your circulation blower. If you have pets the fins can be covered and not moving enough air.

    I have a p68 and it is common for it take a long time for it to cool off and shut down, however when my auger squeals I always scoop my pellets out of my hooper and use a house vacuum to take out remaining pellets and fines around the slide plate, that works 95% of the time. For the other 5% I do need to turn my stove off and scrape out of auger tube. I have found that when I burn high quality pellets ie cubex, VT's, I have no squeling issues. When I burn N. American or Energex my auger squells. my 2 cents.
