Step 2: Check & Clean Grease & Food Debris
- Remove the basket and tray. Check for grease, food particles, or residue on the heating element and fan.
- Use a damp cloth or non-abrasive sponge with mild soap to clean these areas thoroughly.
- Ensure all parts are dry before reassembling.
Step 3: Inspect & Replace Liners
- Ensure you are using the appropriate liners, such as the Cosori Air Fryer Liners or the Air Fryer Paper Liners, and they are correctly placed.
- Never place liners during preheating or without food to prevent them from flying up and touching heating elements.
Step 4: Check for Overloading & Food Moisture
- Avoid overfilling the basket, which can cause grease to overflow and smoke.
- Make sure food is dry before cooking to reduce excess oil and moisture that can cause smoke.
Step 5: Test Run & Monitor
After cleaning and adjustments, run the air fryer empty for 5-10 minutes at a high temperature (around 400°F) to see if smoke persists. If smoke continues, further troubleshooting or professional service may be needed.
