So backstory, had 1 unit.. 2nd gen unit . Smoke exits on side, not top (too bad) anyway, 1st unit failed to properly report temps vs my own temp calcs. Masterbuilt replaced it under warranty. Second unit... worked good for the first few smokes, and now this is where i am at 4-5 months later. I was debating buying the new top exit smoker 40 inch because MB does have good customer service, but does anyone else experience these same heating issues as i do? Or lack there of? Look at these pictures... The unit hasn't even heated yet, it's from just opening the door doing cleaning etc.. you can see all the temp area's have been cleaned, so it's no sludge or anything blocking the temps. You can see i have a igrill AND maverick reporting the same temp of 88... but MB 40incher says 102?? wtf, and it gets worse later on during the smokes... when i start opening and closing the cabinet, the temps get up to 30-50 degrees off..Try smoking at 225 when the unit's cap is 275 and it says it's 280.... and the mav/igrill say it's 210-215. I really like this smoker, but it seems to hate me.
