Check for Food Residue and Grease Build-up
- Unplug the air fryer and allow it to cool completely.
- Remove the basket and any accessories.
- Clean the basket, tray, and interior with warm, soapy water using a non-abrasive sponge.
- Inspect for grease or food residue that may have accumulated, especially around heating elements.
- Dry all parts thoroughly before reassembling.
Ensure Proper Use of Liners and Accessories
- Avoid placing liners during preheating to prevent them from flying up and touching heating elements.
- Use high-quality, heat-resistant liners designed for your air fryer size.
- Place food directly on the basket or on mesh racks to promote airflow and reduce grease buildup.
- Do not overload the basket, as excess food can cause grease to splatter and smoke.
Adjust Cooking Temperatures and Times
If smoking persists, reduce the cooking temperature slightly, especially when cooking fatty or greasy foods. For the COSORI TurboBlaze model, temperatures up to 450°F are available, but lower settings can prevent grease from burning. Always monitor the cooking process and avoid prolonged high-heat cooking that can cause grease to smoke.
Perform a Deep Cleaning of Heating Elements
In cases of persistent smoke, carefully clean the heating element with a soft brush or cloth to remove any grease or dust. Ensure the appliance is unplugged and cooled before doing this. Regular maintenance helps prevent smoke caused by grease buildup on the heating parts.
Tips and Warnings for Safe Operation
- Never leave the air fryer unattended while in use, especially at high temperatures.
- Use the correct accessories compatible with your model to avoid blocking airflow.
- Always unplug and cool down the air fryer before cleaning or inspecting.
- If smoke continues despite cleaning, contact COSORI customer support for assistance.
