Display shows E13 and the refrigerator may not cool or may shut down unexpectedly.

Safety first: Unplug the refrigerator before cleaning or accessing the rear.

Step-by-step:

• Check installation: Ensure there is adequate clearance around the fridge (typically at least a few centimeters at sides and back, and space above) for ventilation.
• Clean condenser: Remove the rear lower cover. Vacuum and brush dust from the condenser coils thoroughly.
• Verify condenser fan: Confirm the fan is clean and spins freely. Replace if seized or noisy.
• Allow cool-down: Leave the fridge unplugged for 30–60 minutes to cool internal components, then reconnect and monitor.

Note: If E13 returns quickly despite good airflow and a working fan, an internal sensor or the control board may be faulty and should be checked by a technician.
