Identify the Cause of Smoking
- Inspect the basket and heating element for grease or food residue. Smoke often results from accumulated grease burning or food particles igniting.
- Check if the basket is overfilled, which can cause excess drips and smoke during cooking.
- Ensure you’re not using plastic or non-heat-resistant liners during preheating or without food, as this can melt and produce smoke.
