I bought a MES 30 last July. I've gotten good use out of it, but a couple weeks ago, my smoker died in the middle of the night. The control panel still comes on and says it was heating but the element wouldn't turn on. I tested the voltage at the connectors of the heating element and there was voltage when I told the control unit to heat. So, I called Masterbuilt and they sent me a new element.
This weekend, I installed the new element and it wouldn't heat, at all. I thought it might be a bad ground so I moved the ground wire to a different location directly on the frame of the unit. The heating element started heating so, I thought I was in good shape. I turned the control unit off but, the heating element kept on heating and wouldn't stop heating until I unplugged the unit from the wall.
Does anyone know what is causing this? Control unit? Improper grounding? Any help would be much appreciated!
