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

Safety first: Use oven mitts when handling hot accessories.

User-level fixes:

• Do not block airflow: Avoid covering the entire basket bottom with foil; leave gaps for air circulation.
• Shake or turn food: Shake the basket or flip food halfway through cooking.
• Correct tray placement: Ensure the crisper tray is properly seated to allow air under the food.
• Smaller batches: Reduce load size to improve airflow.

Advanced:

• Check fan speed: Confirm the fan runs strongly; a weak fan motor may need replacement.
