Wine cooler interior light not working, but cooling is normal.

Safety: Unplug the unit before removing light covers or working on wiring.

• Check door switch: Verify that the door switch operates correctly (light should come on when door opens). Test the switch for continuity and replace if faulty.
• Inspect LED module: Remove the interior light cover (usually clipped or screwed in). Look for burn marks or discoloration on the LED board.
• Test voltage: With power restored and door open, carefully measure low-voltage output at the light connector (follow service manual for expected voltage). If voltage is present but light is off, replace the LED module.
• No voltage: If there is no voltage at the light connector and the door switch is good, the main PCB light driver may have failed. Replace the main control board.
