Thanks for the suggestion, but it didn't work. The auger motor still shut off, but the ignitor stayed lit and burned pellets back into the auger. I'm wondering if I have a bad controller.
I just replaced my ignitor rod, and cleaned out the auger while I was at it. Now when I try to start it back up the auger runs for about a minute, and shuts off before the ignitor catches. It sounds like the auger is turning fine. Any suggestions?
