Interior light does not work but refrigerator cools normally.

Safety first: Unplug the refrigerator before replacing any light components.

Steps:

• Check the door switch operation; if the light never comes on and the switch does not click or feels loose, test and replace the switch.
• Remove the light cover and inspect the LED module or bulb. Replace with the correct type specified by the manufacturer.
• Ensure connectors to the light module are firmly seated.

Note: If a new light and switch do not restore lighting, the control board may have a failed light circuit and should be checked by a technician.
