Safety first: Use a food‑safe thermometer to verify actual food temperature until the issue is resolved.

Steps to improve temperature accuracy:

Verify with thermometer: Place an oven thermometer in the basket and run the air fryer at a known setting (e.g., 180°C). Compare the reading after preheating.
Clean sensor area: Clean the interior, especially around the temperature sensor (usually near the heater or exhaust), to remove grease that can insulate it.
Check sensor mounting: Ensure the NTC sensor is firmly attached to its bracket and located where designed. Reposition if it has slipped.
Replace sensor: If readings are consistently off by a large margin, replace the cabinet NTC temperature sensor.
Control board replacement: If a new sensor does not correct the issue, the control PCB calibration may be faulty and the board should be replaced.

Warning: Always check internal food temperature for safety, especially with meats.

Air fryer temperature seems inaccurate; food undercooks at set temperature or burns quickly.
