If the oven sensor is touching the oven walls, tighten the screws that hold the rod in place. If you can’t move the sensor rod away from the walls, call an appliance repair person before you calibrate your oven.
Remove pots, pans, or sheets so the thermometer and oven racks are the only things in the oven.
For the most accuracy, repeat this for a full hour. This gives you a lot of data for determining if your oven temperature is off.
For example, if your 3 oven readings were 378 °F (192 °C), 362 °F (183 °C), and 355 °F (179 °C), the average temperature is 365 °F (185 °C). Your oven’s temperature is off by 15 degrees—this is the offset number.
Can’t find your owner’s manual? No problem—just search online for the manual to your specific model.
On a GE oven, push the “Bake” and “Broil” buttons for 3 seconds to access the special features (SF) menu. On a Whirlpool oven, press the “Settings” button and keep pushing until the screen shows “Temperature Calibration. " To calibrate a Kenmore oven, press and hold the “Bake” button until you see 00 on the display screen. On older Whirlpool and Frigidaire ovens, press and hold the “Bake” button until the display says “Calibration. "
For a GE oven, press the “Save” button to lock in the new calibration settings and exit out of the menu. Some models, like a newer Kenmore, might have you use the number pad to enter the amount you want to offset the temperature. Then, press “Save” to exit. To save and exit on an older Whirlpool, press the “Enter” button. Sometimes this button is also labeled the “Save” button.
It can be hard to see how much you’re offsetting the temperature. Stick the knob back onto the oven’s panel to see if the temperature dial is now accurate.
The dial might say “Make hotter” on one side and “Make cooler” on the other side so you know which direction to turn the knob.
If you put the knob back on and it’s pointing to a totally different temperature, adjust the dial or shaft and try again. If you loosened the screws to adjust the dial, tighten the screws before you return the knob to its place.
