The Display Control Board is an OEM component specifically designed for LG front-load washing machines. It manages the washer's user interface, enabling control of cycles, options, and preferences through the digital display.

Symptoms of a bad Display Control Board include:

• Glitchy or unresponsive buttons that don't initiate selections
• Faded, pixelated, or blank readout that doesn't convey settings  
• Inability to scroll through cycles or change parameters
• Frequent error codes obscuring the display 

Overextended use can cause circuit degradation within the board. Accidental water damage also risks damage. Replacing with this genuine LG part restores simple, clear operation through an informative display. Owners comfortably manage the appliance. This board fits Sears/Kenmore models as well.
