I'm stuck and not sure what to do. I have 3 butts in the smoker right now and the temp on them does not seem right. They have been in the smoker for 13.5 hours and the temp is only 165 and has not changed for a couple of hours. They are all around 10 lbs each. My digital probe says that the smoker temp is 260 and the therm on the door says 220. I am averaging the 2 and assuming 240. I don't know if I should trust my digital therm any more. Could the heat from the smoker have killed it or maybe low batteries? Do I pull them and hope they are done? I am pretty much a noob at smoking. I have run my smoker(Propane Smoke Hollow) twice. Once with home made venison snack sticks and once with baby backs and brisket. However this is the first time I have done a butt. I know they can take a ling time, but does this seem right?
