How to Regulate Electric Oven Temperature

The electric ovens are able to be calibrated if only slightly off, however, if the temperature is 25 degrees off or more, you should replace the oven sensor. The oven sensor is the device in the oven the detects the temperature. The control board increases or decreases the oven temperature, depending on the oven sensor reading. Before calling a repair technician, attempt to calibrate your oven or change the oven sensor.
