Step 2: Check for Grease and Food Residue
- Open the basket and inspect for visible grease or food particles that may be burning.
- Remove any leftover food or grease using a soft cloth or sponge.
Grease buildup is a common cause of smoking and can be prevented with regular deep cleaning.
Step 3: Clean the Heating Element and Interior
- Use a soft brush or cloth to gently clean the heating element if accessible, removing dust or grease.
- Ensure no food debris or grease remains that could ignite during operation.
Proper cleaning maintains optimal airflow and prevents smoke caused by burnt residues.
Step 4: Use Correct Liners and Loading Techniques
Make sure you’re using appropriate liners like the Cosori Air Fryer Liners or Air Fryer Paper Liners, and do not place liners during preheating. Overloading the basket can restrict airflow, leading to uneven heating and smoke.
Step 5: Adjust Cooking Temperature and Time
If smoke persists, try lowering the temperature slightly and reducing the cooking time. High temperatures (above 450°F) can cause burning and smoking, especially if food is not evenly distributed.
