Fire went out and firebox filled with pellets 8.5 hours into cook

[hardus77]

Hello everyone,

I have been smoking a pork butt today. After 3 hours on the smoke setting I went up to 225 and left it there. It kept cooking there for another 5.5 hours and I was in the middle of the stall when the grill temp suddenly came plummeting down. When I took the guts out to try to figure out what was going on the firebox was completely filled with pellets.tweakbox appvalley https://vlc.onl/

Was this just bad luck?
ETA: I was not opening the lid, I was monitoring the meat temp and grill temp with a ThermoPro TP08 so that I could just let it do its thing.

Was your firebox clean of any ash from previous smoke? I had this happen twice to me on long cooks and the culprit was ash being generated during the cook. I use LumberJack which produces more ash than other brands, What brand were you using? Not sure if this was your problem but something to keep in mind.

Welcome to the forum @hardus77 - Could be just back luck and cleaning could play a big part of it. Check out this thread: https://www.traegerforum.com/threads/cleaning-the-traeger.84/#post-1026

Were you able to get the grill going again to finish the cook?
