Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit before extended handling.
Reset procedure:
- Hard reset: Unplug the air fryer for at least 15 minutes. Press and hold the power/start button for 10 seconds while unplugged to discharge residual power (if accessible).
- Check buttons: Inspect the control panel for stuck or damaged buttons. Gently press each button several times to ensure free movement.
- Try a different mode: After reconnecting power, select a different preset or manual temperature/time setting to see if the error clears.
Internal inspection (advanced):
- Access control board: Remove the control panel cover to inspect the main PCB.
- Look for damage: Check for burnt components, cracked solder joints, or moisture on the board. Dry any condensation and clean light residue with isopropyl alcohol.
- Reconnect harnesses: Reseat all wiring harnesses to the board, including sensors, fan, and heater connectors.
Next steps: If ERR remains after reset and connector checks, the control board is likely defective and should be replaced as a complete assembly.
