Kitchenaid superba oven

SOURCE: KitchenAid Superba double oven: can't set clock.

If you turn the center knob (marked 'time') to the right, it sets the timer; but if you turn it sufficiently far to the left, it goes into clock set mode. When you get to the correct time, press start.

SOURCE: We put this unit on self clean and now it wont turn on nor open.

I had the same problem with a Superba wall oven. In my case, the bracket mount for the door lock warped due to the heat of the self clean cycle. We were able to open the door by inserting a coat hanger into the slight opening at the top of the door and sliding the lock lever to the left. It was a pretty easy self-repair - 1) turn off breaker 2) slide oven out 2-3" 3) remove oven front trim pieces 4) remove screws that mount control panel 5) this should give you access to the door lock mechanism.
good luck
