Do-It-Yourself Story

We called a local appliance repairman. When he arrived it was clear he was only able to guess at a cause and randomly replace parts. Since I am very good at same I sent him on his way with a $55 dent in my wallet. We looked at the specs for the oven on this site and compared notes with several sources on the Googles. The winner seemed to be the "electronic control board", which we quickly ordered from ApliancePartsPros.com. The part arrived in 2-days (paid for 2-day shipping). We removed old part with new. Look at diagrams - you can figure out how to take apart. In the end all went well and oven is working famously. Only word of caution - watch the very top lip of the over behind the control panel. The darn thing is as sharp as a razor blade and then some.
