I was smoking a pork loin had the temp on the MES set at 185. Had my Maverick thermometer in the smoker it read 171. The digital readout on the MES read 232 therefore the heating element would not turn on. WTH?
I have had a mes only for a week, and have done two turkeys in it. I have noticed the same difference in temp. I would rely on the mav and adjust the temp higher to get what you need. I noticed both times the longer it ran the closer the mes temp was with the mav temp. There are plenty of posts on here about the mes temps.
