Refrigerator interior light not working, but unit cools normally.

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

Steps:

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