Identify the Error Code
Check your air fryer’s display panel for the specific error code, such as E1, E2, or other alphanumeric signals. Refer to your user manual for what each code indicates, as different codes point to issues like overheating, sensor errors, or electrical faults.

This step prevents further damage and ensures safe handling during troubleshooting.
Perform Basic Reset

- Plug the air fryer back into the power outlet.
- Turn it on and see if the error code clears or reappears.
Many error codes are resolved through this simple reset process.
Clean and Inspect Sensors
- Remove the basket and interior components carefully.
- Wipe sensors and heating elements with a soft, damp cloth to remove grease or debris that might cause false error signals.
- Check for any visible damage or disconnection in wiring.
Keeping sensors clean helps ensure accurate readings and prevents errors.
Check for Overheating or Blockages
