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

Safety first: Turn off power before accessing the sensor or control board.

• Verify with thermometer: Use an accurate oven thermometer to measure actual temperature at several setpoints (e.g., 180°C/350°F).
• Adjust calibration: Many Blomberg EOCs allow temperature offset adjustment in the settings menu (e.g., ±35°F). Follow the user manual to calibrate.
• Check sensor: If the offset required is large, test the sensor resistance at room temperature and replace if out of spec.
• Inspect door gasket: Ensure the door seal is intact and the door closes tightly. Replace the gasket if torn or compressed.
