OK since it is always the good with no problem post I decided to post my problem. I put a packer brisket in the MES 40 yesterday for an overnight smoke. The normal setup I use with the MES 40 set to 225°-240° depending on when I want it done. This morning I got up and probed the brisket and it was 144°. I was expecting higher but oh well. A few hours later I went to check on it and it was still 144°. That is a strange stall point but oh well. Later when I looked It is 145°. I am thinking this is taking to long. Since I have a bad probe on my Maveric and have been using this MES long enough to have faith in it I am not monitoring the cabinet temp. I decided to use an instant read in the top vent. To my surprise it was 167°. How can this be??? Then the bell went off in my head . I use a foil pan for a drip pan with briskets. I always have and it has never been a problem. However this time I used a larger drip pan that I normally use in my UDS. You guessed it the bottom of the MES was hot but the larger drip pan was keeping the heat blocked. I removed The larger drip pan and replaced with 3 smaller ones that I had on hand. I am now cooking at my set temp.
Since it doesn't matter what time it gets done it is going to turn out fine. It is still in the MES so I will start a different thread to show the cook.
