Genuine LG refrigerator electronic control board that manages refrigerator functions including cooling and defrost timing.

Is This the Right Part?

Common Symptoms

• Refrigerator does not cool or cools inconsistently
• Defrost cycle does not operate normally or frost accumulates
• Compressor or fans do not cycle as expected
• Temperature regulation is erratic
• Controls or display do not respond normally
• Refrigerator operation is intermittent or error codes appear

Check Before Replacing

• Confirm the refrigerator has power and that the outlet and supply cord are functioning normally.
• Record any displayed error codes and compare them with the appliance’s model-specific service documentation.
• After disconnecting power, visually inspect the board area and wiring connectors for loose connections, corrosion, or obvious heat damage.
• Verify that temperature and defrost-related symptoms are not caused by blocked airflow, excessive frost, or another visibly affected component.
• Do not condemn the control board from symptoms alone; refrigerator wiring, sensors, fans, compressor circuitry, or other components can produce similar symptoms.
