Do-It-Yourself Story

First replaced Control Panel Assembly only - ovens worked for about three weeks, then same error code. Next, replaced both Control Panel Assembly and Electronic Control Board. Success! Ovens have now been working great about two weeks. Important that "ribbon" on Control Panel Assembly is securely and correctly attached to Control Board. Wife is happy Easter dinner will go on as planned. *Important note:* In researching this issue on various sites, came to conclusion many people experienced this same problem after using "self-cleaning" feature (which I had done, too). Obviously, high heat and computer boards do not mix. Won't be using this feature ever again.
