Product review (1 stars): Run, run like the wind from KitchenAid cooktops
Unless you love the taste of burnt food, and want to spend a good portion of your evening scraping burnt, boiled over food off the burners, avoid KitchenAid Electric cooktops like the plague.  I call ours the 'electronic abortion'.  As the previous reviewer said, bump the control knobs and the burner lights up, and burns you!  These stoves are pure evil, not meant for any sane person to use.  The burners have some kind of thermostat that turns them hot sporadically, then shuts off just when you think your food might start to cook.  So you turn up the heat; big mistake.  Of a sudden the heat comes on and instantly boils over whatever's in the pot cooking.  It's simply impossible to cook a decent meal on these things.

The oven seems to work ok, but we've already burned out the oven lights once, and a pair of new ones costs like $50.00.  Holy Moly!  For oven lights?

We were lucky, we had a repairmen tell us not to use the self-cleaning function, which will burn out the electronics (most of his repair work was to replace these).
However, we've had to dismantle the entire oven door to clean the glass.  Apparently, the boiled over food from the top somehow leaked down the edge of the cooktop into the door vents right on to the glass, and is then baked on solidly when the oven is used.  Great design Whirlpool (they own Kitchen-Aids)(yes, Kitchen-Aids, that's the only good name for these bogus appliance manufacturers).  May you go bankrupt, and soon.

P.S. I thought the idea of cooktops was to make it easy to clean the burners.  Wrong, wrong, wrong.  Apparently the idea is to make you buy special cooktop cleaner, which doesn't clean the burned on food off worth a damn, so you end up buying razor blades to scrape the crap off.  Never had to to that with the old stove.  And, as an engineer who has worked with computers for many years, I simply cannot believe sensitive electronics would purposely be mounted directly above a 500F heat source.  That's really insane.
