My masterbuilt gas smoker that I received for Xmas seems to have a broken valve. I'm getting enough gas to get the temp up to 100 degrees and turning the gas knob seems to make no difference. I used it a week ago with no problems. I have about 10 lbs of chicken in it right now and I have few questions. 1) Can the valve be fixed and if so how? 2) If the valve can't be fixed can I go ahead and smoke at 100 for a few hours and finish in the oven? Since it is the 4th not much is open and I have about 15 people counting on me for the chicken.
