"Hi, I bought a Masterbuilt 40" smoker model # 20070311 a couple of weeks ago. I have used it 3 times so far. I also have a Maverick ET-732 dual probe thermometer that I use and have used in the past. I have done a low and high temp calibration on it and both probes are within one degree of each other and test out perfect. Yesterday I smoked 3-butts. I started out with the smoker set at 240. I had one maverick probe centered in the smoker and one in the center of one of the butts. I left it this way for 10 hours. The control panel would read between 138 and 142 on the smoker. The maverick probe read between 191 and 193 for the whole 10 hours and the internal meat temp was not climbing past the 130 mark very fast at all. I then turned the smoker up to 275 and the controller said it was there but again my maverick read about 48 deg. less. I left it there for another 5 hours for a total of 15 hours of total cook time. After 15 hours the internal temp of the meat was at 183. I believe something (smoker probe or controller) is way out of calibration. As slow as the meat temp was coming up it would have taken another 5 hours to get to the 205 I wanted but I went as long as I could and still feed everyone. The meat still had to much fat in it at 183 but still doable. Have you ran into this very often and is there a fix? I love the smoker but if it thinks it is at 275 but is really about 50 cooler it will not work. The coil would cycle on and off telling me it though it was at set temp. Thanks Chuck"
If anyone has any input I have open ears. Sorry for the hijack!!!
I would have to know more about it, as it could be a number of things.
It sounds as though you had something blocking the heat from getting much higher than the MES sensor, which is a little below the center on the back wall.
Did you have two of those butts on the same rack?
Were they in pans?
What racks were each item on?
Did you have any other Catch pans on any rack?
Any racks foiled?
Did you have water in your water pan?
Any pics of the inside while it was going?
