Display shows E19 and the refrigerator interior lights may flicker or not work.

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

Identify non-working lights:

• Open each compartment and note which LED modules are dark or flickering.

• Access the LED module: Most Insignia LED modules are behind a plastic lens held by clips or small screws. Gently remove the lens.
• Check connector: Ensure the LED module connector is fully seated. Reseat it if loose.
• Replace faulty LED module: If the module is visibly burned or still does not light, replace it with an Insignia-compatible LED module.
• Test after each replacement: Restore power briefly to confirm operation before reassembling all covers.

Note: If multiple modules fail simultaneously or new modules do not light, the main control board's lighting circuit may be defective and require professional replacement.
