If your KitchenAid wall oven display is not working, the oven control board is the most likely cause, especially when the control has power but the screen is completely dead. A faulty display board is another common cause, particularly when the display is dim, missing digits, or not receiving power from the main control board. If only part of the time, temperature, or settings appear, the LED board may be defective. When the display board has no power, test the main control board, which supplies power to it. A wall oven in lock mode or Sabbath mode may also prevent the buttons and control panel from responding, so check the owner's manual before replacing parts. Less commonly, the KitchenAid control board itself may have failed. These are the main causes of an oven display not working, an oven control panel not working, or a KitchenAid wall oven display missing segments. Disconnect power before testing or replacing the oven control board, display board, LED board, or main control board. Enter your model number to find the exact replacement part for your KitchenAid wall oven.

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 - KitchenAid 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 - KitchenAid 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.
