Our Thermador double oven display has been totally gone for 5 years. The touch pad still works when we press on it. (making the appropriate beep sound and turning on the function correctly). So we never bother to fix the display issue.

Recently, the upper oven bake function (bottom element) no longer works (we have ruled out the possibility of a faulty heating element, as the same element works in the bottom oven).

Would both problem be fixed by a new control board, or do I need to the relay board to be fixed. To get to the relay board, we will have to remove the oven off the wall.

TIA
