E14 error displayed, often with the interior light not working or flickering.

Safety first: Unplug the freezer before working on lighting components.

Steps:

• Access LED module: Remove the light cover inside the freezer (usually clipped or screwed).
• Check connections: Ensure the LED module connector is firmly seated.
• Test LED module: If possible, test the LED module with a suitable low-voltage DC source (if it is a low-voltage module) or check continuity according to the service manual. Replace if non-functional.
• Inspect wiring: Look for pinched or broken wires leading to the light.
• Driver circuit: If the LED module and wiring are good, the LED driver on the main PCB may be faulty, requiring PCB replacement.
