Well, I adjusted the door as it was about 1/16" off from left to right. Pulled top exhaust cover and filter then reinstalled. The error hasnt occurred since. Hope the bug stays away. Thanks for the advice, Jeff.

I believe that is a microcomputer board failure. You will have to replace this board. Website below.

I have gotten parts from "repairclinic" on line and they worked fine. I saved $600 on the last repair of an oven. Good luck.
