Smoker has been on 9 1/2 hrs now smoking approx 10# of Summer Sausage. Started at 120 and has been holding at 176 for the last two hours and the IT is reading at 147 and hasn't moved for the last 1 1/4 hrs. 15 degrees outside but I have attached a picture of the smoker, inclosed under deck and wood surrounding it with a piece of metal in front of it. Did Sticks the other day with no trouble. Any suggestions as to what to do to get this done. Thanks
