Interior light not working, but cooling is normal.

Safety: Disconnect power before working on lighting or door switch components.

Steps:

• Check door switch: Verify that the door switch operates (lights may come on when switch is pressed). Replace if stuck or non-functional.
• Inspect LED module: Remove the light cover and check the LED module and wiring. Reseat the connector.
• Replace LED module: If the module shows signs of burning or does not light with proper voltage, replace it.
• Driver circuit: If multiple LEDs are out and modules test good, the LED driver on the control board may have failed and the board should be replaced.
