Oven temperature too low or too high compared to the set temperature on a Gorenje oven; no error code is displayed.

Safety first: No internal access is required for basic calibration checks.

• Verify with thermometer: Place an accurate oven thermometer in the center of the oven and preheat to a common temperature (e.g., 180°C). Compare actual vs. displayed temperature.
• Adjust settings: Many Gorenje ovens allow temperature calibration in the settings menu (e.g., ±20°C). Follow the user manual to adjust if the difference is consistent.
• Check door seal: Inspect the gasket for gaps or damage that could let heat escape. Replace if necessary.
• Service sensor/control: If the temperature swings widely or calibration cannot correct it, the temperature sensor or control board may be faulty and should be tested and replaced.
