So today I loaded 4 pork butts in my 7 month old MES 40, brought it up to 250 and away we went. After cooking flawlessly for about 4 1/2 hours I noticed both the MES and my Maverick temp probes beginning to fall. The heating element light was till on but it was no longer heating.Temp fell to ambient temperature. Went to Masterbuilt's website and saw that the warranty was only 90 days. I bought the smoker in August, so her I sit with $300 chunk of sheet metal and glass. Gonna tear into it tomorrow but don't have much hope. Anyone have any ideas or suggestions?
