More on uneven Masterbuilt Propane smoker - need help

Discussion in 'Propane Smokers' started by jasontetzlaff, Aug 10, 2014.

  1. Smoked a turkey today and noticed that the thigh that was in the front towards the door got done long before the one that was towards the back.  Led me to check front to back box temps.  Placed one of my maverick 733 probes in the rear and one on the front of the same grate.  Temp varied by 50 degrees!

    I do have a nomex seal around the door and the only place I am getting smoke out is the vent so the box appears to be sealed good.  I do use a foil buffet pan as my water pan and that was centered on the bottom rack so there was even space around it. 

    Has any other Masterbuilt owners noticed this on their box?  Any suggestions?  I do not like to open the door so rotating the meat would not be an ideal solution.  I need some suggestions.  Hopefully others have noticed this and have fixed it.  I could not find anything on the forums that described this issue.

    I was wondering if the seal I put around the door is causing this issue?  Since smoke is no longer escaping through the door it would appear heat isn't either.  Maybe it is part of their design to have it escape.  Is it sealed too good and not venting out the back all the way causing it to increase in temperature?

    Thoughts and suggestions appreciated.

    Is the exhaust vent located in the top near the back of the smoker? That is the set up for my GOSM propane smoker. That may be your culprit. Try putting a diffuser on the highest rack and see if that helps. I did this in my GOSM and it helped even out the heat. I just used a large baking pan that is the size of the rack. I suppose you could wrap the rack with heavy duty foil too.
  4. Exhaust is on the back panel at the top and I always run it wide open.  there is no exhaust on the top of the unit.

    Mine door leaks smoke like it's going out of style. I always thought that it was normal. I get my temp in range and use the vent for fine tuning. Never done a turkey but brisket comes out good.
