Is your Litton wall oven display not working? The oven control board is the most likely cause, especially when the board has power but the screen is completely dead, dim, or missing digits. A failed display board is another common reason for an oven digital display not working. If the display board receives power but shows no information, it usually needs replacement. A faulty LED board can cause partial digits or a dim display, while a failed main control board may stop sending power to the display board. Before replacing parts, check whether the wall oven is in child lock or Sabbath mode, since these settings can prevent the control panel from responding. If the wall oven control panel is not working and the entire display is blank, the control board or main control board is more likely than the LED board. Disconnect power before testing or replacing electronic parts. Enter your Litton wall oven model number to find the exact replacement oven control board, display board, LED board, or main control board for your specific 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).
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 - Litton 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.
