Kenmore ovens are pre-calibrated before they make their way into customers' homes, but there is a chance that your oven was not properly calibrated or perhaps the climate in which you live may necessitate another calibration. If you must consistently change recipe times or temperatures when baking, you may need to calibrate your oven.
Press and hold the "Bake" button on the front display panel for eight seconds. The oven will display "0" if it is set to its factory calibration. If you have calibrated the oven previously, it will display something such as "-2" or "4."
Press the "Up" or "Down" arrow on the front display panel to calibrate the oven. Each time you press the arrow, the temperature calibration changes by 1 degree Fahrenheit. A minus sign appears when you lower the temperature to a temperature less than the oven's original calibration.
Wait five seconds after you reach the number of degrees more or less you want to change the calibration. The oven's display will automatically restore the "Time" display. The calibration is complete.
