Interior light does not turn on when door is opened, but the rest of the unit works.

Unplug the cooler before replacing any light components.

• Check door switch: Verify that the door switch operates (you may hear a click or see the display react). Replace the Luma door switch if it fails continuity tests.
• Inspect light module: Remove the light cover and check for obvious damage. Replace the Luma LED light module or bulb if burned out.
• Wiring: Ensure the light harness is connected to the control board.
• Control board: If the switch and light module are good but no voltage is supplied to the light, the board’s light driver may be faulty and the board may need replacement.
