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

Safety first: Allow the oven to cool before accessing internal components.

• Verify with thermometer: Place an accurate oven thermometer in the center of the cavity and preheat to a known temperature (e.g., 180°C). Compare the displayed temperature to the actual reading.
• Adjust calibration (if available): On digital Essentials models, enter the settings menu and adjust the temperature offset according to the user manual (e.g., ±10–20°C) to match the thermometer.
• Inspect door seal: Check the rubber gasket around the door for gaps, tears, or compression. Replace the door seal if it does not contact the frame evenly.
• Check sensor / thermostat: If the error is large (>25°C), test the temperature sensor resistance or thermostat function and replace if out of specification.
• Retest: After adjustments or part replacement, repeat the thermometer test to confirm accuracy.
