Possible Causes
Failed NTC temperature sensor, Blocked fan or airflow, Grease buildup around heater, Faulty control board temperature circuit
How to Fix / Troubleshooting
Safety first: Unplug and let the air fryer cool completely.
- Check for airflow obstruction: Confirm that the rear and bottom vents are not blocked by walls, cloth, or other appliances. Maintain at least 10 cm clearance.
- Clean interior: Remove basket and pan. Wipe the interior, especially around the heater and fan guard, to remove grease that can trap heat.
- Inspect fan operation: Start a short cycle with an empty, clean basket. Look through the top or rear grill (if visible) to see if the fan spins. If the fan does not run, the unit may overheat and trigger H02.
- Reset and test: After cleaning and ensuring airflow, unplug for 5 minutes, then reconnect and test. If H02 persists, the NTC sensor or control board is likely faulty and needs replacement.
Warning: Accessing the NTC sensor and control board requires disassembly and exposes live circuits. Only attempt if you are competent with electrical safety.
