Unplug and Inspect Your Air Fryer
- Unplug your COSORI air fryer and let it cool completely before inspecting.
- Remove the basket and check for food debris, grease, or grease splatters around the heating element.
- Look for any signs of burned food or residue that could be causing smoke.
Clean the Basket and Interior Thoroughly
- Wash the basket with warm, soapy water, and use a non-abrasive sponge to remove grease and food particles.
- Wipe down the interior, especially around the heating element and fan system, with a damp cloth.
- Dry all parts completely before reassembling.
Check and Replace Liners or Accessories
If you’re using disposable liners or accessories, ensure they are suitable for high temperatures and correctly placed. Do not preheat with liners in place, as this can cause them to burn or catch fire. Consider using a mesh rack to elevate food and prevent grease buildup from touching the heating element.
Properly Preheat and Use Correct Settings
Always preheat your air fryer empty for a few minutes before adding food. Use the recommended temperature settings and avoid overfilling the basket, which can cause uneven heating and smoke.
Inspect Heating Element and Electrical Components
Check the heating element for signs of damage, debris, or discoloration. If damaged or dirty, consult the user manual for cleaning instructions or contact customer support for repairs.
