What’s the infrared sensor?

You may be annoyed when you defrost or reheat food with microwave oven. If you reheat soup, the result is superficial.

The surface is hot but inside of the soup is still cold. You have to set the clock and push “Start” again. The cooking time is much longer than you expected.

LG microwave oven reduce cooking time. Our revolutionary Infrared sensor makes it 3 times faster than the ordinary microwave. Infrared eye tracks the exact temperature of food and regulates the power of the microwave so that the temperature reaches you actually set.

We prepared the temperature LED bar and dial for your precise control and convenience. Infrared sensor means fast and real hot result.
