I have a Kenmore 30'' Self Clean Slide-In Electric Range w/Ceramic Smoothtop Cooktop model 4678, the oven part stopped working about a week ago, turned the oven on everything was fine for the first couple minutes then heard a pop and smelt a electrical burnt smell the whole unit went shut down no light no nothing, checked the fuse box the fuse for the unit was tripped so turned it back on, unit powered up turned the oven on but nothing the bake light would come on but no heat tried to turn it off but the stop button would not work, then turned the cooktop on it works fine, everything seems to work but the oven, tried switching the fuse off/on to see if that would fix it but no luck, oven still not working. Would be very great full if someone could give me some ideas as to what it might be.
