Step-by-Step Troubleshooting

  1. Unplug the air fryer. Disconnect from power and wait at least 5 minutes to allow internal components to reset.
  2. Check for obstructions or residue. Open the basket and inspect for food debris, grease, or blockages that could trigger error codes. Clean thoroughly if needed.
  3. Ensure proper placement of accessories. Make sure all racks, trays, or liners are correctly positioned and not interfering with sensors or heating elements.
  4. Inspect the power cord and outlet. Use a different outlet to rule out power issues. Check the cord for damage.
  5. Reset the device. After cleaning and inspection, plug the air fryer back in and turn it on to see if the error persists.

Advanced Fixes for Persistent Errors

If error codes continue after basic troubleshooting, consider performing a factory reset if your model supports it. Also, verify that the internal sensor is not damaged or dirty. If the error remains unresolved, contact COSORI customer support for professional guidance or potential repairs.

Safety Tips and Warnings

  • Always unplug your air fryer before cleaning or inspecting internal parts.
  • Use non-abrasive cleaners and soft cloths to prevent damage.
  • Do not attempt to disassemble the appliance unless instructed by a professional.
  • If you notice burning smells, smoke, or sparks, unplug immediately and seek expert assistance.
