Food cooks unevenly; some areas are burnt while others are undercooked.

Safety first: Unplug and cool before internal inspection.

• Do not overload: Cook in smaller batches and shake the basket halfway through cooking to promote even airflow.
• Clean fan guard: Remove grease and debris from the fan guard holes; blocked holes reduce airflow in certain directions.
• Check air guides: Some Severin models use metal or plastic baffles to direct air. Ensure they are present and correctly installed.
• Verify fan speed: If airflow seems weak, inspect the fan motor and blades for damage or heavy grease buildup and clean or replace as needed.

Warning: Do not modify or remove internal baffles permanently; they are designed for safe airflow and temperature control.
