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. The oven could also be in “Demo” mode or another mode which prevents full operation. Consult the oven’s user manual for information regarding locking/unlocking the control panel.
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.
Electric wall ovens require 240 volts of alternating current. Gas wall ovens require 120 volts. If an oven won't turn on there could be an incoming power problem. If the breaker hasn’t tripped there may be a loose power cord connection. The wall oven will likely need to be pulled out to check the connections.
The wall oven's control panel will usually display the time, temperature, and settings for the range. If the control panel has power to it but the display is dead, missing digits or dim, it will need to be replaced.
