Error F13 appears and the refrigerator interior lights may flicker or not work, while cooling continues.

Safety: Unplug the refrigerator before removing any light modules or panels.

Steps:

• 1. Identify failed module: Open doors and note which compartment lights are out. Often one failed LED module can affect others in series.
• 2. Remove light cover: Gently pry off the plastic light lens or unscrew the housing to access the LED module.
• 3. Check connections: Ensure the light module connector is firmly seated. Inspect for signs of burning or moisture.
• 4. Replace LED module: If the module is visibly damaged or does not light when swapped with a known-good module (if possible), replace it with the correct Ikea-compatible LED assembly.
• 5. Driver check: If multiple modules are out and no individual module appears faulty, the LED driver circuit on the main control board may have failed and the board may need replacement.

Tip: Avoid touching LED surfaces with bare fingers; use clean gloves to prevent contamination.
