I am new to this forum so I am sure there are several threads here that can help me. My MES 40" is only a couple of years old and the unit is in good shape. However, it will not heat when the control panel lights are on. Masterbuilt, in their generic email suggested a new heating element. So, I bought one and replaced it and surprise, it still does not heat. This makes me think it is the circuit board on the bottom of the unit, but I have no idea how to test that or if it's even replaceable. I was hoping someone here has a solution on how I could use the "shell" of my MES but use an external control to operate it and bypass the MES junk. I did see a thread here on a PID controller, but it wasn't clear to me if that would solve my problem. I will never buy another MES, but right now I don't want to pull the trigger and get a 1k Camp Chef either. Any help or suggestions would be most appreciated. I am trying to get ready for the holidays so my MES crapped out on me at a bad time.
