Unplug and Let Cool
Before starting any troubleshooting, unplug your COSORI air fryer and allow it to cool completely. This ensures safety while inspecting and cleaning internal parts.
Clean the Basket and Heating Area
- Remove the basket and wash it with warm, soapy water. Use a non-abrasive sponge to remove grease and food residue.
- Check the heating element for grease or food buildup. Wipe it gently with a damp cloth or a soft brush.
- Dry all parts thoroughly before reassembling.
Inspect for Damage or Blockages
- Look for any signs of damage, such as melted parts or frayed wiring.
- Ensure the air intake and exhaust vents are clear of dust and debris.
Check for Overfilling and Proper Use
Avoid overfilling the basket, as excess oil and food particles can cause smoke. Use recommended quantities and consider using an air fryer liner to catch drips.
Test the Air Fryer
After cleaning and inspection, plug in the air fryer. Run a short cycle at a lower temperature (e.g., 350°F) to see if smoking persists. If it does, further inspection or professional repair may be needed.
