Freezer not freezing properly while fridge seems normal; no error code.

Safety: Unplug the appliance before cleaning or accessing the rear. Sealed system work involves refrigerant and must be done by a certified technician.

Basic checks:

• Condenser cleaning: Clean dust from the condenser coil and grille at the rear or bottom. Ensure good airflow around the appliance.
• Door seals: Check freezer door gasket for gaps or damage. Replace if not sealing properly.
• Temperature setting: Confirm the freezer is set to the recommended temperature (around -18°C).
• Observe frost pattern (advanced): With the rear freezer panel removed, a healthy system shows even frost across most of the evaporator. Frost only on a small section may indicate low refrigerant or restriction.
• Call a professional: If basic checks do not restore proper freezing, a sealed system diagnosis (pressure, leak detection) and repair by a qualified refrigeration technician is required.
