Oven temperature is inaccurate, food undercooked or overcooked compared to set temperature.

Safety: Use an oven thermometer to verify temperature before making adjustments.

• Measure actual temperature: Place an accurate oven thermometer in the center of the oven and preheat to 180°C. Compare the displayed temperature to the thermometer reading.
• Adjust calibration: Many Hisense models allow temperature offset adjustment in the settings menu (e.g., ±35°C). Follow the user manual to calibrate.
• Check sensor: If the offset required is large, test the sensor resistance and replace if out of spec.
• Inspect door gasket: Replace a torn or flattened door seal that allows heat to escape.
• Rack and load: Avoid blocking airflow with oversized pans or multiple trays touching the walls.
