Not Cold Enough - Refrigerator

[Narrator]

If you notice that your ice cream or frozen pizza is soft, or your milk in the refrigerator is warmer than usual, please follow these instructions to troubleshoot your LG refrigerator.

  • Check to see that your refrigerator is set to its optimal setting.

  • LG recommends 37 degrees for the refrigerator and 0 degrees for the freezer.

  • If additional cooling is required, start by lowering the temperature a few degrees to achieve your desired temperature.

  • Make sure the cooling vents are clear and free from any obstructions.

  • Poor circulation can prevent proper cooling of your LG refrigerator.

  • If you see any obstructions, re-organize the items to ensure good airflow.

  • Check that the doors and drawers of the refrigerator are closing properly.

  • Check to see that the mullion flap is collapsed properly, ensuring good seal for the doors.

  • Make sure that the shelves and drawers are not overloaded preventing the doors from closing tightly.

  • Fully push the freezer doors closed to correct any misalignments, and check for any gaps when it is closed.

Proper leveling is crucial to ensure a tight gasket seal. If you notice that your refrigerator is not leveled, please see our video on leveling and door alignments for further information.

Finally, sour food in the freezer may also be due to odd of the frost cycle. Once defrosting is complete, your freezer will return to normal temperature.

If you feel that your refrigerator is not cooling at all, make sure that the unit is not in display or demo mode.

If you notice that your control panel is displaying the letters O F F, refer to our video on disabling the display mode for more details.

  5. Refrigerator Only

    Watch the video below and follow the recommended steps underneath to troubleshoot cooling issues.

    7 quick steps to follow:

    1. Adjust temperature settings.

      Check to see that the unit is set to its optimal setting. 37 DEGREES is the recommended temperature for the refrigerator and 0 DEGREES for the freezer.

      What is your refrigerator and freezer temperature?

      RECOMMENDED SETTINGS: Adjust the setting to lower the temperature.

      ABOVE RECOMMENDED SETTINGS: Adjust the setting to lower the temperature.

      BELOW RECOMMENDED SETTINGS: You do NOT need to adjust the temperature.

      If the thermometer measures the temperature more than 4°F warmer than the set temperature, this is a normal operation.

      set your temperature
    2. Ensure DEMO Mode is deactivated.

      Your LG refrigerator is equipped with a DEMO MODE or DISPLAY MODE. This feature disables all cooling in the refrigerator and freezer sections to conserve energy while on display in a retail store.

      When DEMO MODE is activated, OF F will appear on the control panel.

      Demo Mode
      How to Deactivate Demo Mode
    3. x

      For most models, to disable DEMO/DISPLAY MODE:

      • With either refrigerator door opened press and hold the REFRIGERATOR and ICE PLUS buttons at the same time for five seconds.

      • After holding the buttons for five seconds, the control panel will beep, and the temperature settings will display to confirm that DEMO MODE is deactivated.

      Refer to your owner's manual for model specific instructions.

    4. Hot food in the unit.

      Adding hot food to the refrigerator compartment will temporarily spread heat throughout the unit. The unit will require some time to cool down the hot food and regulate its internal temperature.

    5. Food is blocking the vents.

      When there is too much food blocking the air vents of the refrigerator, cold air will be prevented from circulating throughout the unit properly.

      Also, just a few items in the refrigerator can cause cooling to be obstructed because the unit will always try to regulate itself when it's circulating too much cold air.

      How to fix this:

      • Re-arrange the food to make sure that it's not blocking the vents.

      • Watch the video below to understand how the unit multi air flow and multi-sensors work.

    6. Frequently opening the door.

      If the unit is opened too frequently, the unit will not be able to maintain a regulated temperature.

      Avoid frequent and unnecessary opening of the door to enable the unit to conserve cold air circulation throughout the unit.

    7. Space to the wall.

      The unit must not be too close to the wall, make sure there is enough clearance on all sides of the unit.

      Recommended spacing:

      • Side space for cabinet: 1/8" from the cabinet.

      • Side space for wall: 2" from the wall.

      • Top space around cabinet and wall: At least 1-2".

    8. Check the door switch.

      If you keep hearing the door alarm sound, even when the door is closed. It means the door switch did not detect the door closing. Thus, cold air will not blow in the unit, and the unit will not get cold.

      How to check door switch

      The door switch may be disconnected. Test the door switch according to it's type and watch if the fluorescent lights in the unit turn OFF.

      Magnetic Reed Switch

      If your unit has two doors, repeat the steps for the LEFT door, using the switch to test if the lights turn off.

      If the lights DO NOT turn off, the door switch may be disconnected. Follow the steps below to check the door switch connection. Even if the lights turn off, check the door switch because a slightly loose connection can cause cooling issues.

      NOTE: After checking all connectors and pushing them in firmly, if you still hear the alarm sound again, the unit will require a repair service. Please visit our Request a Repair page.

    9. Check door sealing.

      When the door is not properly sealing, cold air will escape from the door seal which will prevent the unit from cooling efficiently.

      • Ensure that no food items are blocking the door from closing.

      • Check behind the shelves and drawers to ensure that food and other items have not fallen behind them.

      • When you open the door, you should check if the mullion is working properly as described in the Not Cold Enough - Refrigerator video.

      • If the mullion is not working properly, you will need to adjust the leveling of the door. Please visit our Leveling Instructions - Refrigerator content.
