Step 1: Power Cycle Your Air Fryer
- Unplug the air fryer from the electrical outlet.
- Wait for at least 1 minute to allow internal components to reset.
- Plug the air fryer back in and turn it on.
- Check if the error code clears. If it persists, proceed to further troubleshooting.
This simple power reset often resolves temporary glitches or minor electronic faults.
Step 2: Check for Overheating or Blockages
- Ensure the air fryer is placed on a flat, heat-resistant surface with adequate ventilation.
- Inspect the air intake and exhaust vents for dust, debris, or blockages.
- Remove any obstructions that may interfere with airflow.

Proper airflow is essential for safe operation and accurate temperature control.
Step 3: Reset the Control Panel
- Press and hold the power button for 5-10 seconds to reset the control system.
- If your model supports a reset option through the app, follow the instructions to reconnect and reset.
- Switch the device off and on again to see if the error clears.
- If the error persists, proceed to inspect internal components or contact support.
Step 4: Inspect and Clean Internal Components
- Unplug the air fryer and wait for it to cool down completely.
- Remove the basket and any accessories.
- Clean the interior, heating element, and sensors with a soft, damp cloth.
- Check for accumulated grease, food debris, or damage that could cause sensor errors.
- Reassemble and test the unit.
Regular cleaning helps maintain sensor accuracy and prevents error codes related to dirt or residue.
When to Contact Customer Support
If your troubleshooting steps do not resolve the error code, it may indicate a hardware fault or defective component. In this case, contact COSORI customer support for professional assistance or warranty service. Do not attempt to disassemble or repair internal parts yourself, as this can void the warranty and pose safety risks.
