Food cooks unevenly; back side browns more than front or one side is consistently underdone.

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

• Cooking practice: Avoid overcrowding. Arrange food in a single layer with space between pieces. Rotate racks halfway through cooking.
• Inspect racks and basket: Ensure racks are not warped and are installed in the recommended positions. Replace warped racks.
• Check fan shroud and guard: Remove the rear cover and inspect the fan shroud and heater guard for grease buildup or obstructions that could redirect airflow. Clean thoroughly.
• Sensor position: Verify that the temperature sensor is properly mounted and not bent away from its intended location.
