Interior light not working but freezer otherwise cools normally.

Safety first: Unplug the freezer before working on the light or switch.

Steps:

• Check door switch: Press the switch manually and listen for a click. Test continuity with a multimeter. Replace if faulty.
• Inspect LED module: Remove the light cover and check the LED module and connector. Replace the module if visibly damaged or non-functional.
• Wiring: Ensure the wiring from the switch to the light and control board is intact.
• Control board: If the switch and LED are good, the LED driver on the main PCB may be defective, requiring PCB replacement.
