Tried to turn Oven on.....Oven "CLEAN" light blinking - cannot get oven to come on. (I cleaned oven earlier today...approx. 2.5 hours later I turned "Clean" cycle off by moving oven dial to "OFF" position. When oven was cooled off - I was able to unlock and open door and found oven clean.) Now I want to bake in the oven - but am unable to get Oven to turn on. Did I not let the clean cycle go long enough?? The oven was very dirty and now it's quite clean.
