It's a MasterbuiltPro, 30", propane. I am about to try to make some jerky which calls for a temp of 150. Since I am new to this game I thought that I would give the smoker a test drive. Well, I set it as if I were about to put the meat in, set it to the lowest settings, and opened a beer. The booger never got below 190. I even turned the propane down the farthest that it would go, but no change. This smoker is the one with 2 doors so what the heck. I opened the bottom door and let er rip. It still maintains a temp of 170, measured on the middle shelf using a maverick 732. So what to do. I think that the temps will drop when I put the meat in but will probably come right back up to close to 190. The recipe calls for me to cook the jerky at 150 for an hour with no smoke, then for 5 hours @ 150 with smoke. Do you think that I should just keep everything buttoned up at the lowest temp possible, 190 ? Update in that the temp with the open door is now 160, ambient is 50 with a slight wind.
