Wine cooler interior light does not turn on when the door is opened.

Safety first: Unplug the cooler before working on electrical components.

• Check light settings: Some Lanbopro models allow disabling the interior light via the control panel. Ensure it is not turned off.
• Door switch test: Press the door switch manually with the door open and see if the light responds. Replace the switch if it feels loose or does not change the light state.
• Inspect LED strip: Remove the interior trim and check the LED light strip and its connector.
• Replace LED strip: If the strip is dark and the switch is good, install a new LED light strip assembly.
• Control board: If a new strip and switch do not restore lighting, the main control board LED driver may be faulty.
