This was a new experience, smoker had been running at 250 for about 3 hours when the temp started to drop. It went all the way down to 70 and I saw the white smoke coming out from the back and around the top. I opened the lid, probably not a good idea, that's the first picture. No error code so I put it into shut down mode. Must of been a lot of unburned pellets and a few smoldering because when the fan came on there were flames everywhere, second picture.
I spoke with Weber, they said to clean out the entire smoker and hopper and try it again. This was the first time I didn't use Weber pellets, was using Pit Boss form Lowe's, seemed to have a lot of dust.
Could the dust or Pit Boss pellets be the problem ?
