Check for and Remove Food Residue or Grease
Inspect inside the basket and around the heating element for burnt food or grease. Use a soft cloth or non-abrasive scrubber to wipe away residue. If necessary, use a mixture of baking soda and water for tougher stains, then rinse and dry thoroughly.
Use Proper Accessories and Liners
- Ensure any accessories, like racks or liners, are compatible with your model.
- For liners, avoid placing them during preheating or empty runs to prevent them from flying into the heating element.
- Regularly replace disposable liners to prevent buildup and smoke.
Avoid Overfilling and Use Correct Temperature Settings
Do not overload the basket; leave space for hot air circulation. Use the recommended temperature settings for your recipe, and avoid preheating without food or liners to prevent dry or burnt residue from causing smoke.
Perform a Test Run and Monitor
After cleaning and adjustments, run the air fryer at a moderate temperature without food for 5-10 minutes to check for smoke. If smoke persists, repeat cleaning or inspect for damage.
