Possible Causes

Aging NTC sensor with shifted resistance curve,Grease buildup on sensor and cavity walls,Inaccurate internal calibration on main board,Weak convection fan reducing heat distribution

How to Fix / Troubleshooting

Safety first: Unplug and cool before internal cleaning.

Steps:

  • Use an oven thermometer: Place a reliable oven thermometer in the basket and run the air fryer at a known temperature (e.g., 180°C). Compare the reading after 10–15 minutes.
  • Clean interior: Remove grease from the cavity, especially around the sensor and heater guard, to improve heat transfer.
  • Check fan operation: Ensure the fan runs strongly; weak airflow can cause hot or cold spots.

If the measured temperature is consistently off by a large margin, replace the NTC sensor. If inaccuracy persists, the main control board's calibration may be off and the board may need replacement.
