Food is unevenly cooked; some areas are burnt while others are undercooked.

Safety: Unplug before internal checks.

• Do not overload: Cook in smaller batches and shake the basket halfway through cooking to promote even airflow.
• Check vents: Ensure rear and side vents are not blocked by walls or objects.
• Inspect basket: Check that the basket mesh is not warped or blocked with grease. Clean thoroughly or replace the cooking basket if damaged.
• Verify fan speed: Listen for strong airflow during operation. If airflow is weak, inspect and clean the fan and heater guard. Replace the fan motor if it runs slowly or intermittently.
