The safe approach
Food-grade, heat-rated silicone can be safe but may reduce browning and airflow.
- Keep airflow paths and the heating element clear.
- Use only heat-safe materials that fit securely in the basket.
- Check the instructions for your exact appliance model.
When to stop
Stop cooking if you notice melting, sparks, flames, electrical odors or repeated heavy smoke. Unplug the appliance and contact the manufacturer when the cause is unclear.
