Good only when NEW, versus Like New/Brand New!
It IS No Frills, but at this level, as easy to clean, even manually as it is to use--and probably tons more reliable than its self-cleaning (and much more than NEWER) counterparts!
Have the cabinet space & installation skills & it will make a great second oven to your free-standing (or a third if you own a double oven) range, or will go with just about any cook top...
I guess it's easy to imagine how much grief the new oven that former owner is willing to put himself through, just because he probably dis-likes the color and just wants a thing like self-cleaning--especially powered by that unable to withstand the rigors of that single microprocessor unit w/ an incompatible touch-pad system, that when merely depicted on The Jetsons could never make it through even ten- of the forty-to-fifty-years-ago, that at least that simple GE could give & may there be much more ahead...
