Inspect and Replace Accessories
Ensure that any racks, liners, or trays used are compatible with your COSORI model. Avoid using paper liners during preheating or without food weight, as they can catch fire or cause smoke. Consider using a mesh rack like the ALJ 3PCS Air Fryer Oven Mesh Rack for even air circulation and reduced risk of smoking.
Check for Grease or Food Residue
Look for grease splatters or food residue around the heating element or fan area. If present, clean thoroughly as described in the first step. Regular cleaning prevents buildup that could burn and produce smoke during operation.
Adjust Cooking Habits
- Reduce the temperature slightly if smoke persists, especially when cooking fatty foods.
- Preheat the air fryer without accessories or liners to avoid trapping grease or food particles.
- Use appropriate accessories designed for your model to ensure proper airflow and safety.
Perform Regular Maintenance
Establish a routine cleaning schedule after every few uses to prevent grease buildup. Periodically inspect the fan and heating element for dust or residue and clean as needed.
