I'm on my second year with my Harmon P68. All of a sudden I'm having issues with it firing up. The pellets won't feed until I put it in test mode for a few seconds, sometimes it starts to feed then stops and I need to do it again. I'm using Cleanfire pellets this year and I'm wondering if they are the problem. We shut it down at night (lower the temp knob) and it used to just slowly die out.. Now I notice it glows for hours and the other night it never did shut down. Do you think it could be the pellets or some other problem.
