I am taking the advice of Bearcarver and starting a new thread with my problem. I am reposting my 2 postings here so hopefully someone out there can help me out. POST #1 This is my first effort at amy posting anywgere so please bear with me. I have a MES 40" that I have had for about 18 months that has stopped working. However I do not seem to be having the same wiring problem that has been described and resolved so wonderfully here. My MES powers up fine and the electronic control works. I can program in the target temp and the time just fine but as soon as it tries to turn on the heating element it trips the GFCI. I have tried a different outlet and that one triped also. I have removed the back and I cannot see any problems with any of the wiring, Any suggestions???? POST #2 Unfortunately there is no access panel so I drilled out the umpteen hundred rivits. There is no visible evidence of any wiring problem. None of the wires are scorched or turning brown. All the connections are tight and clean. Wiring does not seem to be the problem which leads me to think that it is an electronic problem. I am fairly good at fixing electrical wiring problems but I am at a complete loss when it comes to "electronics". There is a "box" mounted in the bottom panel that I looked in and there is no indication of a problem there. I contacted MES and since it is a discontinumed model all they could do is offer me a discount on their new model. I'ld love the new one but there is still too much life in this one if I can bring it back from the dead to be shelling out that kind of money yet. Anybody know anything about the controler box in the bottom? Thanks for any ideas.
