At this point I'm very concerned. I threw the chuck on several hours ago. I know the smoker was sitting in sunlight for about half the afternoon. The chuck has been stalled, for a lack of a better word, for the past 3 or 4 hours. I was expecting a stall around 170 or 180. Not at 2 hours to go from 144 to 156, and then just sitting there. Am I missing something here? Is there something I can do to speed up the process?
