How To Calibrate an LG Oven

Oven 6

In the world of culinary arts, precision is key. Having an oven that heats to the correct temperature is crucial for successful cooking and baking. If you own an LG oven and suspect that it might not be heating accurately, it’s time to calibrate it. This comprehensive guide will walk you through the process of calibrating your LG oven, ensuring your meals are cooked to perfection every time.


To calibrate an LG oven, first, ensure the oven is clean and check its temperature with a metal oven thermometer. To access calibration settings, turn off the oven, press and hold the “Start Time” button for 3 seconds until “ADJU” appears on the display. Use the “+” or “-” buttons to adjust the temperature in increments of 5 degrees Fahrenheit. Press “Start” to save the changes. Verify the calibration using an oven thermometer. If the temperature is still off, repeat the process.

Familiarize Yourself with the Oven

Before you start the calibration process, it’s important to familiarize yourself with how your LG oven operates. Use it for a few weeks to understand its cooking behavior. New ovens might cook differently than older models, so understanding how your specific model works is beneficial before you make any adjustments.

Pre-Calibration Steps

Before diving into the calibration process, ensure the oven is clean and free from any insulation, plastic films, cardboard, or zip ties. The kitchen should be well-ventilated to dissipate any strong odors or smoke that may occur during the process.

A vital step before calibration is checking the oven temperature with a metal oven thermometer. Place it in the oven on the middle shelf, facing outward where it is easy to read. Set the oven to 350°F and wait for it to reach the intended temperature. The thermometer reading will help you determine if the oven temperature is accurate or needs calibration.

Accessing the Calibration Settings

To access the calibration settings on your LG oven:

  1. Turn off the oven.
  2. Press and hold the “Start Time” button for 3 seconds. This will enter the calibration mode.
  3. Press the “Start Time” button repeatedly until “ADJU” appears on the display.
  4. Use the “+” or “-” buttons to adjust the oven temperature up or down as needed. You can adjust the temperature in increments of 5 degrees Fahrenheit.
  5. Press the “Start” button to save the changes.

Calibrating the LG Oven

Once you’ve accessed the calibration settings:

  1. Start by adjusting the thermostat up or down by 15 degrees Fahrenheit. Press “Start” to accept the change.
  2. Test the oven with this adjusted temperature to see if it suits your preferences.
  3. If the oven still needs adjustment, raise or lower the thermostat again using the first adjustment as a gauge.
  4. Continue adjusting the thermostat until the oven is calibrated to your satisfaction.

Please note that this adjustment does not affect the broiling or self-clean temperatures. The adjustment will be retained in memory even after a power failure.

Verifying the Calibration

To ensure the accuracy of the calibration, use an oven thermometer. Place it in the center of the oven, set the oven to 350°F, and let it preheat. Compare the thermometer reading to the oven’s display to ensure they match. If the temperature is still off, repeat the calibration process.

Troubleshooting Common Issues

Some common issues that can arise during the calibration process include inaccurate oven temperature, faulty heating element or igniter, and thermostat issues. Most of these can be resolved by calibrating the oven temperature, replacing the faulty heating element or igniter, or replacing the thermostat.


Calibrating your LG oven might seem like a daunting task, but with this comprehensive guide, you can easily adjust your oven’s temperature for accurate cooking. Remember that if the oven’s temperature is off by a significant amount, it’s recommended to call a technician and not attempt to calibrate it yourself. Enjoy your precisely heated oven and the delicious meals that come with it!

Frequently Asked Questions

How often do I need to calibrate my LG oven?

Calibration of your LG oven is not a regular maintenance requirement. It is only necessary when you notice that your oven’s temperature seems off, or your food is consistently undercooked or overcooked.

Can I calibrate my LG oven to a temperature higher than its maximum range?

No, you can’t calibrate your oven to exceed its maximum temperature range. The calibration process only fine-tunes the oven’s existing temperature range for accuracy.

What if my LG oven doesn’t have the “Start Time” button?

Different models of LG ovens might have different button configurations. If your oven doesn’t have a “Start Time” button, refer to the user manual for your specific model to find the correct button to access the calibration settings.

My oven is still not heating correctly after calibration, what should I do?

If the oven temperature is still off after calibration, it could be due to a faulty heating element, thermostat, or igniter. It’s best to contact a technician to diagnose and fix the problem.

Can I use a digital thermometer to check the oven temperature?

Yes, you can use a digital thermometer to check the oven temperature. However, ensure that it is an oven-safe thermometer designed to withstand high temperatures.
