Wine cooler interior light does not turn on when door is opened; display and cooling work normally.

Safety: Unplug the unit before removing the light cover or handling wiring.

Steps:

• 1. Check light settings: Some LG models allow disabling the interior light via the control panel. Ensure it is not turned off in settings.
• 2. Inspect light assembly: Remove the light lens and visually inspect the LED module or bulb for damage or discoloration.
• 3. Test door switch: Verify that the door switch is working by checking if the display recognizes door open/close (if applicable). Replace the switch if faulty.
• 4. Check wiring: Ensure the light connector is firmly attached to the harness and not corroded.
• 5. Replace light module: If the switch and wiring are good, replace the LED light module or bulb with the correct LG part.
• 6. PCB diagnosis: If a new light does not work and voltage is not present at the light connector when the door is open, the main control board's light driver may be defective and require replacement.
