Possible Causes
Partially blocked fan or air outlets, Warped or overloaded basket, Failing convection fan motor, Faulty temperature sensor placement
How to Fix / Troubleshooting
Safety: Unplug and cool before internal inspection.
- Usage adjustments:
- Do not overfill the basket; allow air to circulate around food.
- Shake or turn food halfway through cooking as recommended.
- Clean airflow paths:
- Remove any debris from the fan guard and air outlets.
- Clean grease from the interior surfaces that may disrupt airflow.
- Check fan operation:
- Listen for consistent fan noise; intermittent or weak airflow suggests motor issues.
- Internal checks (advanced):
- Inspect the fan blade for damage and replace if needed.
- Verify the NTC sensor is correctly mounted in the air stream, not bent away or loose.
- Replace components: Replace the convection fan motor or fan blade if airflow is weak or uneven. Reattach or replace the temperature sensor if mispositioned.
