-- If you're knowledgeable or a little daring, here's a great deal on a 30-inch GE electric built-in wall oven --
I bought 2 identical unused ovens several years ago from a resale store. They had been pulled from a homebuilder's model homes, which is why they were never used. Anyway, this one turned out to not heat up. I pretty much ignored it ever since, but I recently hooked it up again and took some pics. It seems to get 110V just fine, because it goes through all the motions as far as the display goes, and you can even hear the heating relay click - but apparently it isn't getting 220V to either the bake or the broil element, because neither will get hot or even warm.
Worst case, it might need a control board ($125 new on eBay), or it may be something stupidly simple. But even if it's the first, you'll have a never-used name brand oven for a fraction of buying new. I do want to mention that there are some minor flaws from sitting around without a box, mainly some scuffs on the handle. It's in the North part of Norman if you want to see it.
