I also thought I was "self-cleaning" my oven while out, but when I got home, realized I did not push "start". Ugh! I then decided to go ahead, push start, and open lots of windows since it was warm enough to do it. However, I don't think the oven did anything since now I have a locked oven door and weird codes that I tried to figure out and correct. This will lead me to call a repairman first thing Monday!
BSoleille! The bright side of fresh air with opening up the windows!
