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

Safety first: Use oven mitts when handling hot components.

Usage adjustments:

• Do not overcrowd the basket; leave space for air to circulate around food.
• Shake or turn food halfway through cooking as recommended in the manual.

Mechanical checks:

• Clean the air inlets and exhaust vents to ensure unobstructed airflow.
• Verify the fan runs smoothly and at full speed; replace the fan motor if weak.
• Inspect the heater shield for warping or misalignment; straighten or replace if it directs air unevenly.
