Basic Reset and Power Cycle
- Unplug the air fryer from the power outlet.
- Wait at least 1 minute to allow internal components to reset.
- Plug the unit back in securely.
- Turn on the air fryer and check if the error persists.
This simple reset can clear temporary glitches causing error codes, especially after power surges or minor electrical disturbances.
Inspect and Clean Vents and Sensors
- Remove the basket and any removable parts.
- Use a soft cloth or brush to clean dust or grease from vents and sensors.
- Ensure the fan spins freely and is free of obstructions.
- Reassemble and test the unit.
Overheating or sensor errors often result from dirt buildup. Keeping these parts clean ensures proper airflow and sensor function.
Check Electrical Connections
Ensure the power cord is firmly plugged into a working outlet. If your outlet has multiple devices, try plugging the air fryer into a different socket. Inspect the cord for visible damage or fraying, and replace if necessary. Confirm that the control panel is responsive and that no loose wires are visible inside the unit (if you are comfortable opening it).
When to Contact Support
If error codes persist after performing the above steps, consult Cosori customer support. Provide them with the error code, a description of the issue, and the troubleshooting steps you’ve already taken. Professional repair or replacement might be required if the error indicates a faulty component that cannot be easily fixed at home.
