MES 40 Gen 2.5 temp swings and uneven temps!

I have a MES 40 gen 2.5 model number MB20075118 that I purchased at Sams club a couple years ago but have not really used it much. Today I did some snack sticks. I was getting 20-30 degree temp swings. I had a probe of my Inkbird meat thermometer hanging down through the vent monitoring the temp inside the smoker. For instance if the controller was set on 155 I was getting swings from 160-195 on my inkbird probe. Are these swings normal?

Also I had probes in my snack sticks as well. The probe in the ends of my sticks on the right side (as you are facing it) was 20 degrees hotter then the probe in the middle. To get the middle of the sticks to 150 the ends were 170. I tried to rotate the racks but the ends still got too done.

Are these swings normal and has anyone came up with a baffle or something to keep the right side from getting hotter?

Thanks!

Lots of guys here use the 'lectric smokers. Hang tight you'll get your answer.

Temp swings in mes smokers are very common! Several people use an auber pid to control the smoker, which you can keep your temps within a couple degrees. If you look in Bearcarver Bearcarver step by steps he has many different smokers listed that he has tested and also I believe show how he has his set up to keep more even temps.

Thanks Bear. Have you come up with a way to keep the right side from getting so hot? It seems in your review you had even temps in your gen 2.5.

The biggest help in the Gen #2.5 was when they made the change I was squawking about for years. They moved the top vent from the back right to the back left. With that, the heat & smoke has to cross over through the middle of the smoker to go from bottom right to top left.
With the top vent on the right in so many MES units, the heat goes up the right side, from the bottom right side heating element to the top right Vent. (No reason for it to leave the right side). That's why my Heat deflector I used in my Gen #1 worked so good---It kicked the heat over from the bottom right to the middle of the smoker.
