I have a harman p68 that normally works fine until tonight. the stove was down for a few hours as it was warm here in albany today, but it just cme on a little while ago. I noticed that the flame was much larger than usual. Upon looking at the burn pot i noticed it was over full of pellets. I keep my feed at 3. now it has been 10 minutes since i shut the stove down, and every minute or so I can here the feed motor running pellets into the burn pot. Wouldn't the stove stop feeding once i have shut it off?? Please Help!!
