Interior light not working when door is opened, but refrigerator cools normally.

Safety: Unplug the refrigerator before removing light covers or switches.

Steps:

• Test door switch: Press the switch manually and see if any lights flicker. If not, remove the switch and test for continuity when pressed.
• Replace switch: Install a Sharp-compatible door switch if it does not change state.
• Check LED module: Remove the light cover and inspect the LED board. Replace the module if visibly burnt or cracked.
• Inspect wiring: Ensure connectors are firmly seated and wires are not pinched.
