I Setup my MES30 for smoking a 10 pound pork Butt by setting the panel temp to 225 and inserting two separate probes down the smoke vent.
When the panel show the temp at 225 the two probes showed 235 and 240. So I adjusted the MES to 205 then the probes were at 225 to 230.
I started smoking. At about 155 degrees it look like it hit the wall and it stayed there (155) for about 2 hours. At about 12 hours in, it read 180 and I went to bed thinking at about 3am or 4am the meat would be at about 190-200. I check on it a 3am and to was 181 at 4am it was 181 at 6am it was 182. This was about 21 hours of cooking. I did open the door several times at the start trying to get the AMNS going.
With a temp of 225 for that long a period of time it would be much higher than 180 degrees. MY theory is that the two probes used to test the MES probe we wrong and I cooked the Butt at 205 at this time. The MES was correct. What is your ideas on what could have caused the 180 degree Butt after 21 hours of cooking as what I thought was 225-230?
