Fire

What temp was your grill set to?

200 F

Wow, that's strange at such a low temp.  Are you sure it's not just smoke coming through the auger and out through the hopper?

Pellets in auger were black and burning.

@usj - Sometimes when it has been a little too long since I last swept out my firepot I will have pellets get stuck on the little chute between the discharge and firepot and they will catch on fire at the top of the chute.

Otherwise, I frequently get alot of smoke feeding back through the pellet hopper, but thankfully no fires yet.

One of two things, you either had saw dust build up in the bottom of the pellet hopper or you had the smoke stack facing in a way that allowed a strong wind to blow into it. Usually it's the saw dust build up that has caused this problem for me in the past.

hey @cal 2!  About how often does this happen to you?  Just curious if I am overdue and should plan a day in the near future to empty out the pellet hopper and give it a good vac.

Has happened Twice. I think it has to do with speed of feed mechanism.  I had just cleaned it when it happened again.

The same thing happened to me. I had that issue while cooking low (250°) and long (5 hours or more). I talked to a craftsman from https://firerecruitmentaustralia.com.au , and he told me that I should clean it more often or every time I use it. His advice was to take everything out of the grill and start it up. Once the start-up process is done, increase the temp to 250, then close the lid until it reached temp. Then, open the lid and keep an eye on what it is doing to see if the drill keeps filling the pot and not stopping. That's it.
