Set up my generation 1 MES 40 from Amazon today and did the burn in. Temperatures are consistent front to back, and remarkably consistent top to bottom. None of the variability that others have had trouble with. (Obviously, this wasn't skill on my part, but I'm OK with dumb luck So two thumbs up for the gen 1. One *tiny* issue. I did the burn in at the recommended 275. All my thermometers say the unit hit 265 and locked in. As long as I'm doin' recipes that want 265 or lower, this is easy. But if I actually want 275 in the smoker ... is there any way at all to make minor adjustments to that MES thermostat? I don't want to send it back for a replacement--I feel remarkably fortunate that everything is working so well and I don't want to make things worse. So it's just a question ... is there a way to make minor adjustments? TIA. And thanks especially for all the advice on this forum. I'm a beginner, but I feel I've landed a great starter kit ... MES 40 gen 1, AMNPS, MAV ET-732, 5-day smoking course, plus a couple of hanging Cooper-Atkins ... and that it was you guys who put me on the right path. What a way to start a brand new year! Next stop ... finding a butcher who will help me feed this frenzy.
