Finally getting my first smoke on my new Masterbuilt 140S-40. I am using my Maverick and have both probes in top part of smoker. Started setting at 225 and was only getting to 190. I rose to 250 and than 275. At 275 it is reading 220 on both probes. My 30" is dead on. On top of that the remote display quit working few minutes in. Changed batteries and no help. Unplugged smoker and started back up. Looks like temp off about 50 degrees.
