I have a 2nd Gen MES 40 that I got from Lowes a little while ago. I've tried smoking ribs, turkey, and chicken in it a few times but have noticed some temperature issues: 1) Temperature doesn't heat to set temp.. Seems to be about 25 degrees cooler than what it's set to. 2) Hot spot on right side of smoker. Only way to counter that is to rotate what I'm smoking but then that requires me opening the door up and then it takes forever to recover. 3) The controller pad at the top is bubbling! I keep it covered at all times when not in use and out of direct sunlight. I also never place hot pans or trays on top of the smoker. The past few times I've smoked, I would have to just take things out of the smoker and finish in the oven because it would just take too long or one side would overcook while the other remained undone. Ribs I've tried smoking using 3-2-1 method would just be dry. I haven't been happy with this smoker at all and I'm frustrated because it's passed the return window. Would appreciate any help here or is this just a loss I have to cut?
