Last night I put a brisket on @224 degrees. When I checked it this AM the unit was off. The high temp limit switch had flipped. While cleaning it out, I noticed that the pellets in the auger were burnt. There wasn't anything on the chute or in the fire pot. I turned the unit on and ran it until all of the burnt pellets were cleared from the auger. This is a new/clean FEC 100 with Cookshack pellets.
