Step 2: Check and Clean the Basket and Interior
- Remove the basket and inspect for grease, food particles, or oil residue that may be causing smoke.
- Wash the basket, tray, and interior with warm soapy water. Use a soft brush or sponge to remove stubborn residue.
- Dry all parts thoroughly before reassembling.
Regular cleaning prevents buildup that can lead to smoking during cooking.
Step 3: Examine and Use Proper Liners
If using liners (such as Cosori or other disposable liners), ensure they are placed correctly—never during preheating—and are fully covered with food to prevent them from flying up and touching the heating element.
Step 4: Check for Oil or Food Spills on Heating Element
Inspect the heating element for any oil or food splatters. If you see residue, carefully clean it with a soft, damp cloth once the unit is unplugged and cooled.
Step 5: Prevent Overloading and Use Correct Temperature Settings
- Avoid overfilling the basket, which can trap grease and cause smoke.
- Use recommended temperature settings (up to 450°F) and avoid excessively high temperatures for prolonged periods.
This reduces the chance of grease overheating and producing smoke.
