I have a one year old 30" MES. The one with the Stainless windowed front door and the inside light with a meat probe. I probably have about 50 hours smoking on it. I used it recently without a problem when it was in the mid 50's outside. A few days later I went to use it the temps were in the low 30's, so I brought the unit inside to warm up and then took it back outside. When I pluged it in it tripped the GFI outlet. I took it to another GFI outlet and it tripped that one too. I brought it back inside and plugged it into a regular outlet and it was fine. I ended up running an extension cord to it outside to do my smoke. I later called Masterbuilt and described the probe and they told me the the Element was going bad, that's why the GFI was tripping. They also said that 50 hours is about the lifespan for the Element. Has anyone else had an experience like this and is the information from Masterbuilt accurate?
