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

Safety: Unplug and cool before cleaning or adjustment.

• Clean airflow paths: Remove basket and pan. Clean the heater guard, side walls, and exhaust vents to restore proper airflow.
• Check fan strength: Run the unit empty and feel airflow from the exhaust. Weak airflow suggests a failing fan motor that should be replaced.
• Sensor position: Verify that the temperature sensor probe is correctly clipped in its bracket near the heater or air outlet, not dangling or touching metal surfaces.
• Cooking practice: Avoid overloading the basket and shake or turn food halfway through cooking for best results.
