Yesterday I smoked a nice Tri-tip, last night I noticed smoke coming out of the feed hopper. I used a shop-vac to pull out as many pellets as I could before my grill went up in flames. Any ideas why this happened?

The issue is the auger did not stop running as it continued to feed pellets into the fire pot. Once the fire pot gets engulf in flames as the fan is pushing more air feeding causing the increase heat then starting a fire going down your auger tube into the hopper.

Pellet dust is just a myth as I never have empty my hopper and I have used over 35 different brands of pellets. The amount of pellet dust to be in your auger tube would be so enormous to start a fire and I bet you had little to no dust in your auger tube..

I would contact Pit Boss as you have a bad PID controller that malfunction. The number of hopper fires are very rare and when they do happen it is due to a malfunction with the control board. You can ask any Pellet grill manufacture they would tell you the same thing.
