Interior light does not turn on when door is opened, but cooling works normally.

Safety warning: Unplug the cooler before removing light covers or accessing wiring.

• Check door switch: Verify that the door switch (magnetic or plunger) is working by observing whether the display indicates door open/closed. If the switch is faulty, replace the "Door switch".
• Inspect light module: Locate the interior LED light strip or module, usually at the top or sides of the cabinet. Check for loose connectors or visible damage.
• Replace LED module: If the module is dark and connections are good, replace it with a "Phiestina LED light module" for your model.
• Control board check: If a new light module does not work, the light driver circuit on the "Main control board" may be faulty and require board replacement.
