My dad told me about this story yesterday and funny thing it happens to me today. I had to do a cook last night for a job today and what do you know, same thing. Meat went on at 5 at night, I checked it at 6 am, everything was good, went back out at 8 to start loading my truck up and something didn't smell right. I opened up the door and noticed that the pellets started to stick on the ramp and went up towards the auger. In the hole were 3 pellets that were on fire. I caught it in time to pull them out with tongs and had to smash the firepot down and scrap off the pellets from the ramp. Thank god they didn't go up into the hopper.
