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

Safety: Unplug the wine cooler before working on the light or switch.

• Check door switch: Press the door switch by hand and see if the light flickers. Test continuity with a multimeter; replace the door switch if faulty.
• Inspect light assembly: Remove the light cover inside the cabinet. Check for loose connectors or visible damage to the LED module or bulb.
• Replace light: Install a new LED light module or bulb specified for your Summit model.
• Control board: If switch and light are good but still no light, the main control board light output may have failed and require replacement.
