The LG 438L Double Door Top Mount Freezer Refrigerator has all the features you want, and then some. With LINEAR Cooling™, your food stays at a consistently cool temperature without having to go through the up-and-down swings of ordinary cooling systems. The DoorCooling+™ system means that you can leave your freezer door open while taking out your food, because it will stay cold for hours. HygieneFresh+™ keeps bacteria from growing on the refrigerator surface, so no more worrying about who touched what last. And Smart ThinQ™ provides a voice control experience that makes food shopping easier than ever.
