Oven temperature is inaccurate, food undercooked or overcooked

Safety: Use heat-resistant gloves when placing or removing thermometers.

• Verify with thermometer: Place an oven-safe thermometer in the center of the oven and preheat to a known temperature (e.g., 180°C / 350°F). Compare displayed vs actual temperature.
• Door gasket: Inspect the door seal for gaps or damage. Replace if compressed or torn.
• Sensor test: If the temperature is consistently off by more than 15–20°C, test the sensor resistance and replace if out of spec.
• Control calibration: Many Ilve models allow temperature offset adjustment in the settings menu. Adjust by the measured difference according to the user manual.
