Refrigerator interior light is not working, but the unit cools normally.

Safety First: Unplug the refrigerator before replacing bulbs or LED modules.

Steps:

• Replace the bulb: On models with screw-in bulbs, replace it with the correct wattage appliance bulb.
• Check the LED module: If it's an LED, remove the light cover and test for voltage at the module. Replace the module if it has power but does not light up.
• Test the door switch: Press the door switch manually. If the lights flicker or never come on, test the switch for continuity and replace it if faulty.
• Ensure all light connectors are fully seated.
