I have the Harman Accentra FS, three years old. I opened the hopper lid to load some pellets & the stove went to turn off. Closed the lid real quick & it turned right back on. I have since opened the door to clean the ash & refilled the pellets without it doing that again. It happened to me one night weeks ago in the same way but I thought there might have been a minor power surge as to why it did it then. I searched to find an answer but didn't find one. Anyone know why it did it? I do not want that to happen again. Scared me!
