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

Safety first: Unplug and cool the unit before inspection.

• Step 1 – Avoid overcrowding: Cook in smaller batches and shake or turn food halfway through the cycle.
• Step 2 – Clean heater and fan guard: Remove grease and debris from the heater guard and fan intake to restore proper airflow.
• Step 3 – Check fan speed: Listen for weak or inconsistent fan noise. If the fan seems slow, inspect and possibly replace the convection fan motor.
• Step 4 – Verify sensor position: Ensure the temperature sensor near the heater is properly clipped in place and not touching the element directly.

Warning: Do not bend or relocate the sensor excessively; it must remain in the designed position for accurate control.
