Oven Temperatures

You should use an oven thermometer to test your oven for temperature accuracy. We would recommend that you repeat your tests every six months or so, because ovens can go out of temperature at any time.

To test your oven temperature:

• Place your Oven Thermometer in the center of the oven, so it is visible through the oven door*
• Set the oven to 180°C / 350°F and allow it 20 minutes to preheat
• Take a temperature reading without opening the oven door
• Take three more temperature readings, every 20 minutes – again without opening the oven door
• When you have four readings, calculate their average
• The average temperature should fall in the range 160°C to 190°C / 325°F to 375°F*
• For average temperatures outside of the above range you should look to have your oven serviced

*For ovens without a glass door use a thermometer with an oven proof external probe

**Oven temperatures will oscillate within a calibrated range in order to maintain the heat at the specified temperature.
