Step 2: Check for Residue and Buildup
- Remove the basket and inspect for grease, food particles, or oil splatters.
- Clean the basket and interior thoroughly using warm soapy water or a non-abrasive sponge.
Step 3: Remove or Adjust Liners
If you’re using liners, check if they’re causing smoke. Remove them to see if smoke diminishes. Make sure liners are properly placed and not covering the heating element or restricting airflow.
Step 4: Reduce Cooking Temperature and Time
Set the temperature lower, especially if cooking greasy or sugary foods. Avoid exceeding 400°F unless the recipe specifically calls for it, as high heat can cause smoke.
Step 5: Check for Overfilling
- Ensure the basket isn’t overfilled; leave space for hot air to circulate evenly.
- Remove excess food or oil to prevent smoke and ensure even cooking.
