Food cooks unevenly, with some areas burnt and others undercooked.

Safety first: Unplug and cool the unit before internal inspection.

Steps to improve cooking uniformity:

• Do not overload: Cook in smaller batches and shake or turn food halfway through the cycle to promote even exposure to hot air.
• Inspect basket perforations: Ensure the basket holes are not clogged with grease or food. Clean thoroughly.
• Check fan and vents: Remove the basket and drawer. Inspect the top of the cavity for blocked air outlets or a dirty fan guard. Clean with a soft brush.
• Verify fan operation: Listen for consistent fan speed during cooking. If the fan surges or slows, the convection fan motor may be failing and should be replaced.
• Replace warped basket: If the basket is bent or warped, airflow patterns can be disrupted. Replace with a genuine Kalorik basket assembly.

Even with a properly functioning air fryer, shaking or stirring food during cooking is recommended for best results.
