If your Maytag wall oven display is not working, the oven control board is the most likely cause, especially when the board has power but the display is completely dead. A failed control board can also cause an oven control panel not working, missing digits, or a dim display. Next, check the display board. If it has power but the oven display is still blank, missing segments, or dim, replace the display board. A partially visible display often points to a faulty LED board, while a completely dead display makes the control board more likely. If the display board is not receiving power, the main control board may be defective because it supplies power to the display. Also check whether your Maytag wall oven is in lock mode or has the child-lock or Sabbath feature enabled, since that can prevent the buttons from responding. Less commonly, the control board that communicates with the display has failed. Disconnect power before testing or replacing parts. Enter your model number to find the exact replacement control board, display board, LED board, or main control board for your Maytag 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).
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 - Maytag 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.
