I've done two 8lb butts over the last few days, was surprised that they took about 18 hours, starting at 225, then bumping to 235, 245,meat finally got to 195, turned out great. I do not have a probalem with a 18hr cook time, but here is my question.
I have the Q set for 225, been smoking about 1.5 hours at 225, no probe, as I'm going chicken quarters, inserted Thermogen and a Thermogen wire unit into the vent holes, just so see what the temp read, and BOTH came out at 165 or so. While I was taking the temp at the top of the unit, is there that much of a temp spread?
I plan to get a few potatoes later today, and insert both the Q probe and the Thermogen in them on different height racks.
I'd hate to think that I have a defective heating element or thermostat.
