LG Range display board not working

If your LG range display is not working, the oven display may be completely blank, dim, or missing digits even though the range has power. The most likely cause is a faulty oven control board, especially when the control board has power but the display remains dead. A failed display board can cause the same oven display not working symptom, while a defective LED board is more likely when only part of the display is missing or dim. If the display board is not receiving power, the main control board may be unable to send power to it. Before replacing a part, confirm the range has incoming power by checking that the oven light or burner sparks on a gas range, or that the surface elements turn on for an electric range. Check for a tripped breaker, blown fuse, loose power connection, or an engaged child lock or Sabbath mode that prevents the control panel from responding. Enter your LG range model number to find the exact replacement oven control board, display board, LED board, or main control board for your appliance.

03 - LG Range/Stove/Oven LED Board

The range'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 - LG 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.

05 - Incoming Power Problem

Ensure plug is tightly pushed into electrical outlet and outlet is supplying power. If the display board is not working, there could be an incoming power problem. A gas range has power if the oven light comes on and the burner sparks; an electric range has power if the surface elements turn on. If the range does not have power, check for a tripped circuit breaker or blown fuses and correct as needed.

06 - Range in lock mode

Many ranges have a child lock or "Sabbath" feature which will prevent the buttons from being used when the feature is engaged. Consult the range's user manual for information regarding locking/unlocking the control panel.
