Oster air fryer temperature is inaccurate; food undercooks or overcooks compared to the set temperature.

Safety: Unplug the unit before adjusting any internal components.

• Verify with thermometer: Use an oven-safe thermometer placed in the basket to compare actual temperature to the set temperature over a 10–15 minute cycle.
• Clean sensor area: Locate the temperature sensor near the heater and clean off any heavy grease or residue that could insulate it.
• Straighten sensor bracket: Ensure the sensor is positioned in the airflow, not pressed against metal surfaces. Gently bend the bracket back into place if needed.
• Replace sensor: If readings are consistently off by a large margin and cleaning/positioning do not help, replace the NTC temperature sensor with an Oster-compatible part.
• Control board: Persistent large errors after sensor replacement may indicate a miscalibrated control board, which would need replacement.
