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

Steps to improve cooking uniformity:

• Shake or turn food: For chips, nuggets, and similar items, shake the basket halfway through cooking to redistribute.
• Do not overcrowd: Leave space between items so hot air can circulate.
• Check basket fit: Ensure the basket sits flat in the drawer and the drawer closes fully.
• Clean vents and fan guard: Remove grease and debris from the top grill and side vents to restore airflow.
• Check fan speed: If airflow seems weak or fan noise is reduced, inspect the fan motor and blade for faults (see fan entries).
• Verify sensor position: Ensure the NTC temperature sensor is correctly attached to the heater housing so the control board can regulate temperature accurately.
