Step 2: Remove and Inspect the Basket
- Remove the basket carefully from the unit.
- Check for grease, food residue, or burnt debris on the basket and heating element.
- Wipe down the basket and clean the heating area with a damp cloth or soft brush.
Step 3: Clean the Heating Element and Fan
- Use a soft brush or cloth to gently remove any dust, grease, or food particles from the heating element and fan area.
- Ensure no debris is blocking the airflow, which can cause overheating and smoke.
Step 4: Check and Replace Liners Properly
Make sure you are using appropriate liners, like the Cosori Air Fryer Liners, and follow safety instructions. Do not place liners during preheating or without food, as this can cause smoke or fire hazards.
Step 5: Conduct a Test Run
After cleaning and inspecting, run the air fryer empty at 400°F for 5 minutes to see if smoking persists. If smoke appears, recheck for residue or damage.

Why is my COSORI air fryer smoking even after cleaning?
Residual grease or food particles on the heating element or basket can cause smoking. Regular cleaning and proper use of liners help prevent this.
Can I use paper liners during preheating?
No, avoid placing liners during preheating, as they can fly up and catch fire. Use liners only when food is placed on top and the unit is at temperature.
What should I do if cleaning doesn’t stop the smoke?
Inspect for damage or burnt components inside the unit. If persistent, contact COSORI customer service for professional assistance.
