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

Safety first: Unplug before internal inspection.

Steps to improve cooking evenness:

• 1. Adjust loading: Do not overfill the basket. Cook in smaller batches and shake or turn food halfway through.
• 2. Check fan performance: Ensure the convection fan runs strongly and continuously during cooking. If weak or intermittent, inspect and replace the fan motor.
• 3. Clean vents and guard: Remove grease and debris from the fan guard and exhaust vents to restore proper airflow.
• 4. Inspect fan shroud: Inside the housing, verify the fan shroud is properly positioned and not warped, which can redirect airflow. Replace if damaged.
