Well..An update
After using the Kenmore for a few months, I thought I would report on its performance, As for the top units, great, could not work any better, the large unit is very fast and the seven heats make a wonderfully responsive cooktop, the oven, just as I figured, not as good as a Frigidaire, don't get me wrong, it bakes ok, but the main problem is the door, and this is a issue with most of these old Kenmores, up to about 375, all is fine, but turn it up over 400 and the door liner warps just enough to gap the door open about a quarter of an inch, the weird thing is, after 20 to 30 minutes it warps back and the door closes, but by this time the front of the cooktop is so hot you can burn yourself on it, the problem with it is there is no way to adjust it, for a cake it does ok, as John L has said, it does not brown as well as a range with top heat, but it isn't terrible, biscuits and other high heat items brown fine...if you prop a chair against the door to keep it closed, LOL, I STILL maintain, the old Norge baked better than anything I have used, Frigidaire would be second, I know Donald hates the color, but my Avocado early 70s Frigidaire is still all the way around, about as good as it gets, and I think I will go back to it, the KM is beautiful, but pretty is as pretty does a lot of times.
