If your Thermador wall oven display is not working, the oven control board is the most likely cause, especially when the display is completely dead even though the wall oven has power. The oven control board operates the time, temperature, and cooking settings, and it should be replaced if it has power but shows no display. A failed display board is another common cause. If the display board has power but remains blank, shows missing digits, or looks dim, replace the display board. For a display with only partially missing or dim digits, the LED board may be faulty. If the display board is not receiving power, check the main control board, which supplies power to it and may need replacement. Also check whether the wall oven is in child lock or Sabbath mode, since this can prevent the control panel buttons from responding. Less commonly, the control board that communicates directly with the display may be defective. Before ordering, enter your Thermador wall oven model number to find the exact oven control board, display board, LED board, or main control board replacement part that fits your appliance.

If the display board is dead it may not be getting power from the main control board. If there is power to the display board but the display is dead, missing digits or dim, it will need to be replaced.
The wall oven's LED board will usually display the time, temperature, and settings for the range. If the display only partially shows digits or is dim, it's likely the LED board is faulty and should be replaced (if the whole display is not working, a defective control board is more likely the cause of the problem).
04 - Thermador Range/Stove/Oven Main Control Board
The main control board sends power to the display board to operate. If the display board is not receiving power, the main control board is likely bad and will need to be replaced.
Many wall ovens have a child lock or "Sabbath" feature which will prevent the buttons from being used when the feature is engaged. Consult the oven's user manual for information regarding locking/unlocking the control panel.

06 - Thermador Range/Stove/Oven Control Board
For many wall oven's, the control board interacts directly with the display to show the time, temperature, and settings for the range. If the control board has power to it but the entire display is not working, the control board is likely at fault and will need to be replaced.
