Well I don’t know what happened but it scared the hell out of me. I put two pork butts on my Mak this morning at 6:45 running on smoke for 2 hours then up to 290 for the remainder of the cook. I had a flame out at about 3 o’clock, I restarted it and about 20 minutes later I heard a loud bang and the lid flew up and back down. I open the smoker and flames were going everywhere so I closed the lid back to smother the fire with the smoke. I emptied the pellet hopper In case the flames went back through the auger. As of right now she is still smoldering. Any idea what could have caused this? I am glad I was home and around when it happened, it could’ve been bad. I had just cleaned it out real good this morning as well so that shouldn’t be an issue. I’m gonna be honest and say I’m kind a gun shy right now using it again especially whenever I’m away from the house or asleep as I’ve done in the past. Luckily I was able to salvage the butts but they are finishing up in the oven right now.
