I replaced a MB smoker that went belly up. Couldn’t get support on fixing, so bought a new one. I smoke a lot of fish at 150-ish. New smoker wouldn’t generate smoke at 150. MB recommended the cold smoker attachment. That works better, but can only get main smoker to 90. So I find I have run the heat element and set main smoker temp control to 150. A bit more fussing around than I thought...but it works!
