What You'll Learn

Using an oven thermometer
Oven calibration is a process of adjusting your oven's temperature settings to ensure accuracy. To calibrate your Hotpoint electric oven using an oven thermometer, follow these steps:
Firstly, place a rack in the centre of the oven cavity. Oven thermometers usually hang vertically from the upper rack, so you can peek through the glass for a reading. If your oven doesn't have a window, you'll need to quickly open the door to check the temperature. Place the thermometer on the rack, centring it as much as possible.
Next, set the oven temperature to 350°F (177°C). It's important to keep the thermometer in the oven during preheating and not to open the door, as this can cause inaccurate readings. Wait for the oven to preheat completely, indicating it has reached the full temperature.
Once the oven is preheated, check the thermometer's reading. If your oven has a window, you can read the temperature through the glass. If not, open the door briefly to check and then quickly close it. If the oven thermometer shows a reading that deviates from 350°F by 15 degrees or more, calibration is necessary.
To calibrate your oven, you can refer to your owner's manual for specific instructions. Typically, digital display ovens allow temperature adjustments through the keypad. You can access the "calibration mode" by holding down specific buttons and then use the arrows to adjust the temperature accordingly.
It's worth noting that electric ovens tend to be more accurate than gas ovens, and oven thermometers provide a reliable way to determine if your oven's temperature matches its settings.

Checking the oven sensor
Oven temperature can be verified by using a dial thermometer or a digital thermometer with the wire lead end touching a cast-iron skillet placed in the oven to keep the temperature reading even. Place a rack in the center of the oven cavity and center your thermometer on the rack, then close the door.
Set the temperature to 350℉. Keep the thermometer in the oven during preheating and do not open the door – this could cause inaccurate readings. Wait for the oven to completely preheat, indicating it has come to full temperature. Check the thermometer’s reading through the oven door. If your oven door does not have a window, open the door and check the temperature before closing it quickly.
If the oven temperature is over or under by 35 degrees Fahrenheit (2 degrees Celsius), the oven thermostat, oven sensor, or oven control (depending on the model) is likely at fault. If the temperature is within 35 degrees (2 degrees Celsius) above or below the set temperature, it can likely be recalibrated successfully.
If the oven temperature is off, you should test the temperature sensor and other components first before considering replacing the control board. If you confirm the other components are working properly, you can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance's wiring diagram.

Adjusting the temperature
Oven calibration is the process of adjusting your oven's temperature settings to ensure accuracy. This process is necessary when your oven is running too hot or too cold. Ovens heat in cycles, so it's normal for the temperature to fluctuate a little. However, if the temperature is off by more than 10 degrees, you should consider calibrating your oven.
To calibrate your electric oven, you will need an accurate oven thermometer. Place a rack in the centre of the oven and position the thermometer on the rack, then close the door. Set the oven temperature to 350°F (177°C) and allow it to preheat completely. Keep the oven door closed during preheating to avoid inaccurate readings. Once the oven is preheated, check the thermometer's reading through the oven door or by quickly opening the door. If the thermometer reading deviates from the set temperature by 15 degrees or more, calibration is required.
For a digital oven, access the calibration menu by holding down the appropriate buttons, such as "Bake" and "Broil" or "Settings." Once in the calibration menu, use the "+" or arrow keys to adjust the temperature based on the thermometer reading. Push the buttons by the amount you want to offset the temperature.
For an analog oven, you may need a Phillips-head screwdriver. Remove the temperature knob and locate the screws and shaft. Twist the shaft in the direction you wish to calibrate. If your analog oven lacks a shaft, look for a dial at the back of the knob and twist it to calibrate.
It is important to note that if your oven's temperature is off by 100 degrees or more, do not attempt to calibrate it yourself. Instead, contact a certified technician to address the issue.

Calibrating a digital oven
Oven calibration is the process of adjusting your oven's temperature settings to ensure accuracy. This process is a great way to get the most out of your oven when baking or roasting. While some ovens are designed to run slightly cooler or hotter than their specified temperatures to improve performance, you may want to calibrate your oven if it runs too hot or too cold, or if you are not satisfied with the baking quality and times.
To calibrate a digital oven, you will need to access the calibration menu. Usually, you have to hold down the "Bake" and "Broil" buttons or the "Settings" button for a few seconds to access this menu. Once you have accessed the calibration menu, use the +/- or arrow keys to program the amount to offset.
Different oven brands may have different ways to access the calibration menu. For example, on a GE oven, you need to push the "Bake" and "Broil" buttons for three seconds to access the special features (SF) menu. On a Whirlpool oven, press the "Settings" button 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."
It is important to note that if your oven's temperature is off by more than 10 degrees, you will need to calibrate it. To check the temperature, place an oven thermometer in the center of the oven, set the oven to 350 °F (177 °C), and preheat the oven. Do not open the door during preheating as this could cause inaccurate readings. If the oven thermometer shows a reading that is above or below 350 °F by 15 degrees or more, you will need to calibrate your oven.
If your oven's temperature is off by 100 degrees or more, do not try to calibrate it yourself. Instead, contact a certified technician to schedule appliance service.

Calibrating an analog oven
Oven calibration is the process of adjusting your oven's temperature settings to ensure accuracy. This is a great way to get the most out of your oven when baking or roasting. It is a relatively simple process for an electric oven with analog temperature control.
Firstly, you need to check your oven's temperature to know how much you need to calibrate it. Place a rack in the centre of the oven cavity and centre a thermometer on the rack. Close the door and set the temperature to 350℉. Keep the thermometer in the oven during preheating and do not open the door, as this could cause inaccurate readings. Wait for the oven to completely preheat, indicating it has come to full temperature. Check the thermometer's reading through the oven door. If your oven door does not have a window, open the door and check the temperature before closing it quickly. If the oven thermometer shows a reading that is above or below 350℉ by 15 degrees or more, you will need to calibrate your oven.
Take ten total readings, recording when the burner turns off and on again. Record five times it turns off at the high points and five times it turns off. Average the readings to determine your oven's offset. For example, if your three 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. The result should be within 10 degrees of 350 °F (177 °C). If it's off by more than 10 degrees, you'll need to calibrate your oven.
To calibrate an analog oven, pull off the temperature knob. You should see some screws and a shaft—twist the shaft in the direction you wish to calibrate. If your analog oven does not have a shaft, check the back of the knob for a dial—some models require you to twist that to calibrate instead.
