Oven temperature is consistently too hot or too cold compared to the set temperature.

Safety first: Turn off power before removing the sensor if testing or replacing.

• Verify with thermometer: Use an accurate oven thermometer to compare actual temperature to the set temperature over several cycles.
• Adjust calibration: Many Thermador ovens allow temperature offset adjustment in the settings menu (e.g., ±35°F). Follow the user manual to calibrate.
• Sensor test: If the offset required is large (>25°F), test the sensor resistance at room temperature and replace if out of spec.
• Airflow: Avoid blocking convection vents with large pans and ensure racks are placed per recipe recommendations.
