When a Samsung wall oven display is not working, the oven display may be dead, dim, or missing digits even though the wall oven has power. The most likely cause is a faulty oven control board, which operates the display and should be replaced if it has power but shows nothing. Next, check the display board. If the display board is receiving power from the main control board but remains blank or dim, the display board may be defective. A failed LED board is more likely when only part of the digits or settings are missing. If the display board is not receiving power, the main control board may be faulty because it supplies power to the display. Also check whether the wall oven is in lock mode or Sabbath mode, since these settings can prevent the control panel from responding. A less common cause of an oven control panel not working is a control board failure where the board directly operates the display. Enter your Samsung wall oven model number to find the exact oven control board, display board, LED board, or main control board replacement part for 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).
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 - Samsung 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.
