Interior lights not working but refrigerator otherwise runs normally.

Safety first: Unplug the refrigerator before replacing light modules or working near wiring.

Steps:

• Check door switch: Press the door switch manually and see if any lights flicker. Test the switch for continuity.
• Inspect light modules: Remove the light lens and check for obvious damage or discoloration on LED boards.
• Replace module: Swap a suspected bad LED module with a known good one (if identical) to confirm.
• Harness check: Ensure connectors to the light modules are fully seated.

Corrective action: Replace failed LED light modules or bulbs and any faulty door switches. If multiple modules are out and switches are good, the main control's light driver may be defective and require board replacement.
