We bought this oven a little over a year ago.  The oven no longer heats evenly.  The oven racks fall down when you try to slide them in and out spilling what you are baking.  The smooth range top marks and discolors.  We have used several smooth top range cleaners trying to make it look better.  The window in the over has leaked and can't be cleaned.  We are now looking for a new stove after spending $1000 a year ago.
