If your oven is cooking or baking your food unevenly, it may need temperature calibration.
Use an oven thermometer to see if calibration is required. Place the thermometer inside the oven and set your oven to a temperature of your choice. After around 30 minutes, check the thermometer to see if it’s showing the temperature you set.
If your oven is running hot or cold, it needs calibration. Please contact an authorised service agent to have your appliance calibrated.
