Here are some simple steps you can take to improve the cooling efficiency of your LG refrigerator.

  • Your refrigerator needs to be leveled in order for the doors to open, close, and seal properly.

    If you need instructions on how to level the unit, click here.

  • LG refrigerators have recommended default temperature settings (Refrigerator: 37°F, Freezer: 0°F). Make certain that the temperatures for both the freezer and refrigerator compartments are set properly. The more food that is in the unit, the hotter the ambient temperature of the room or the more the unit is opened and closed, the cooler that the unit should be set. This is because it will take more for the unit to keep cool.

    It is also important to know that the inside temperature and the external settings display may vary +/- 5 degrees.

    If you made changes to your current settings, allow the refrigerator approximately 24 hours to stabilize.

    • Check the vents in all compartments.
    • Relocate any items that might be blocking the vents.
    • Check the model specific owner's manual for recommended food storage locations.

  • Visually inspect the doors to make sure that they are aligned correctly. Run your hand along the rubber door seals, feeling for any areas where cold air is able to escape. If the doors are not aligned properly or the refrigerator is not sealing properly, cold air will escape and thus prevent the unit from maintaining the set temperature.

    If the door seals are damaged, the unit will require repair service.

    Each time the doors open, cold air escapes and warm air enters the unit. The digital sensors in the unit will pick up on this and turn the compressor back on to cool the unit back down. If the doors are being opened and closed frequently, the unit will not be able to maintain temperature settings. Leave the doors shut to cool the unit.

  • If a lot of food or hot food items have been added to the refrigerator recently, the refrigerator compartment will temporarily warm, requiring the unit to run longer to bring it back down to the set temperature. Please allow enough time for the unit to cool back down. How long will vary depending on the amount of food added and the settings of the unit.
