Interior lights not working when doors are opened.

Safety first: Unplug the refrigerator before replacing light modules or switches.

• Test door switch: Press the door switch manually. If the display or fans respond but lights do not, the switch is likely good and the light module may be bad.
• Inspect LED module: Remove the light cover and check the LED light module for burn marks or discoloration.
• Replace LED module: Disconnect the module and install a new OEM module. Do not substitute non-approved LEDs, as they may overload the control board.
• Switch replacement: If pressing the switch does not change anything, replace the door switch.
