Step 2: Clean the Basket and Interior
Remove the basket and clean it thoroughly with warm, soapy water. Use a non-abrasive sponge to remove grease or food debris that can cause smoking. Wipe the interior, especially around the heating element and fan, to eliminate grease buildup.
Step 3: Check and Replace Liners
If you use disposable liners, ensure they are placed correctly. Never preheat with liners in place, and always have enough food to prevent liners from flying up. Consider using liners designed for high heat, like the Cosori Air Fryer Liners, which resist up to 465°F.
Step 4: Inspect Heating Element and Fan
Look for signs of damage, soot, or food debris on the heating element and fan. If dirty, carefully clean with a soft brush or cloth. If damaged, contact customer support for repair options.
Step 5: Test Run
After cleaning and inspection, run the air fryer at a low temperature without food for 10-15 minutes to see if smoking persists. Monitor closely to ensure all issues are resolved.
