Ordered a new control board. It arrived on schedule and the installation was very clear and easy. Only issue is this was a newer version of the control board and is housed in a separate metal box that seems to be crammed into the free space inside the dos house and attached with double sided tape.
I fabricated a bracket to attached it to the housing so it would not rattle. I think the retrofit could have been engineered a little better to attach to the housing.
The Thermador has rattled off and on since new and I had to fabricate rods to fit between the top of the box and the top of the dog house to keep it from rattling.
