Air fryer runs but food cooks unevenly; some areas are burnt while others are undercooked.

Safety: Unplug and cool the unit before cleaning internal parts.

Steps to improve cooking uniformity:

• Reduce load: Avoid overfilling the basket; cook in smaller batches and shake or turn food halfway through.
• Clean fan guard and vents: Remove the basket and pan. Clean the fan guard and top of the cooking chamber to remove grease that can disrupt airflow.
• Check external vents: Ensure rear and top vents are not blocked by walls or objects.
• Inspect fan: If accessible, check that the fan blades are clean and intact. Clean gently with a soft brush.
• Replace warped basket: If the basket is bent or warped, replace it to restore proper airflow patterns.

Tip: Use perforated parchment liners designed for air fryers to maintain airflow while reducing sticking.
