Step-by-Step Troubleshooting Guide
- Unplug and Reset: Always unplug the air fryer before troubleshooting. Wait at least one minute, then plug it back in to see if the error clears.
- Inspect the Basket and Liners: Remove the basket and check for food debris, misplaced liners, or blockages that could affect sensors or airflow. Clean thoroughly if needed.

- Test the Temperature Sensor: If the error persists, inspect the sensor (usually located near the heating element). Look for visible damage or disconnection. Do not attempt repairs unless qualified.
- Overheating or Fan Issues: If overheating occurs frequently, verify that the unit is not placed near heat sources or in a confined space. For fan problems, listen for unusual noises or check for blockages.

Preventative Maintenance to Avoid Future Errors
Regular cleaning and proper use are the best ways to prevent error codes. Always clean the basket, fan, and vents after use, especially if cooking greasy or sticky foods. Use compatible liners like the Cosori Air Fryer Liners to keep the basket clean and free from residue.
