We have a Whirlpool range with the ceramic cook surface. It's only a few years old. While I was cleaning it (yes I clean the oven ) I hit the "Auto clean" button and locked the door. I interrupted the auto clean cycle and now when I try to use the oven I get an error message on the digital display. I've tried just unplugging it hoping it would reset but no luck. From the manual it says to call the repairman for this error The stove top still works fine but no oven and I hate microwave pizza Anyone???
