I have had a GEN 2 MES40 for almost two years. I typically only use it September - May, don't smoke much during the summer out in the heat. It is stored on my deck under a pretty thick waterproof grill cover that is bungee corded around the smoker. i recently had the typical wiring issues, rigged it up with some 12G wire I had to get by during a smoke but had problems with the unit turning off repeatedly during the smoke. I was not tripping the breaker or anything, would just simply shut off and I would be able to get it back on a few minutes later. I ordered some high temp 12G wire and SS push connectors and completely rewired it. Been testing it out recently and had some isssues like before where it would turn off but not trip anything. I have finally been able to get it to run normal, but have noticed that when it does run correclty it is not in direct sunlight and not 80+ degrees outside on my deck. I am starting to wonder if it is the heat and direct sunlgiht shining on the top of the box and the control panel that is cuasing it to get hot and shut it down. I have definitely seen some correlation lately of it running flawlessly on cloudier and cooler days. Anybody else had issues with this ?
