The last 2 times I tried to do a low and slow smoke my fire has went out and the auger kept feeding to try and get the temperature up. Last night I put 2 brisket points on at 200 degrees, I watched the smoker for a couple hours without opening the lid and everything was going well, a little temp swing but nothing major. This morning ( roughly 7 hours later) I went out to check the smoker and the temp was flashing 65 degrees, when I opened the lid to investigate it erupted in flames. I got the meat off the smoker and the racks off before it got really hot. When I lifted the burner cover the entire bottom of smoker was covered in pellets and starting to burn like hell. I unplugged the smoker and eventually got the pellets out and the fire out. I cleaned the burner out and plugged it back in and decided to check it and it works fine. WHAT IN THE HELL IS GOING ON?
