Wine cooler interior light does not work but cooling is normal.

Safety: Unplug the unit before working on the light assembly.

• Check door switch: Verify that the door switch operates correctly (light should come on when door opens). Test continuity and replace the switch if faulty.
• Inspect LED module: Remove the light cover inside the cabinet. Look for signs of burning or moisture. If the LED board is dark and cracked, replace it.
• Test voltage: With caution and the unit powered, measure voltage at the LED connector when the door is open. If correct voltage is present but the LED does not light, replace the LED module.
• PCB check: If no voltage is present and the door switch is good, the light driver on the PCB may have failed; replace the main PCB if necessary.
