Hey pags! I burnt a batch last night in the first hour. I couldn't figure it out at first and then I realized, I put the cookie sheet in the bottom position. This created a baffle, and burnt that tray. The top tray which was a smaller cake pan, was fine. Guess I usually have them switched for a reason. Wasn't thinking last night. Anyways-Thought I would share, so that it doesn't happen to anybody else.
One good thing was I was testing my new thermometer and it started beeping at 240. I thought that's weird I had the smoker set for 225 and the thermometer set to go off at 240 to warn me if something went wrong. Before I realized what was happening, the smoker reached 260 and so I decided to open the door. I could see that the bottom batch was already black. All this happened one hour in. That element must have been trying to heat up but the internal thermometer wasn't getting any heat because of the baffle.
