morning, I shut down my pellet stove this week as I had gone away for thanksgiving. I came back yesterday and cleaned out the stove and started it up. The pellets lit and there was a fire, however it shut down shortly after that and the e2 code appeared. I have tried to start it up a few times again and nothing just the e2 codes again. When I go remove the non burned pellets they are hot to the touch.. Any ideas?
