Refrigerator not cooling in fresh-food compartment but freezer seems cold; no error code displayed.

Safety first: Unplug the refrigerator before removing internal panels or working near moving parts.

Steps:

• 1. Check temperature settings: Ensure the fridge and freezer are set to recommended values (e.g., +4 °C fridge, -18 °C freezer). Extremely low freezer settings can reduce airflow to the fridge.
• 2. Inspect air vents: Look for vents on the rear or side walls of the fridge compartment. Move food containers away from vents to allow free airflow.
• 3. Look for frost or ice: If you see frost around the vents, unplug the unit and leave doors open for 12–24 hours to fully defrost internal ducts.
• 4. Check damper operation: On models with a motorized damper, remove the cover (usually at the top rear of the fridge compartment) and observe if the flap opens/closes when temperature is adjusted (requires brief powered testing; use caution).
• 5. Replace faulty damper: If the flap is stuck, broken, or the motor does not respond, replace the Siemens air damper assembly.

Tip: Avoid overpacking the refrigerator; good airflow is essential for even cooling.
