    Why is my LG LFX25991ST not cooling in the freezer and refrigerator sections?
    • S
      Steven CooperAug 20, 2025
      Your LG Refrigerator may not be cooling because the control is set to OFF. Turn the control ON. It could also be in the defrost cycle, so wait 30 minutes. If the refrigerator was recently installed or relocated, it may take up to 24 hours to reach the desired temperature, or if relocated, it needs to stand upright for 24 hours before connecting it to power.

    What to do if my LG LFX25991ST or Freezer section is too warm?
    • J
      Jenna Perry MDAug 22, 2025
      If your LG Refrigerator or Freezer section is too warm, it might be because it was recently installed and needs up to 24 hours to reach the desired temperature. Check if air vents are blocked and rearrange items to allow airflow. Reduce the frequency and duration of door openings. Ensure the unit is not in a hot location (above 110F). Allow hot food to cool before placing it inside. Also, check that the doors are closing correctly and that the temperature control is set correctly. Finally, wait 30 minutes after a defrost cycle to confirm the proper temperature has been restored.

    Why is my LG Refrigerator icemaker not making enough ice?
    • D
      djohnsonAug 25, 2025
      Your LG Refrigerator icemaker may not be making enough ice if the demand exceeds its capacity (approximately 100 cubes in 24 hours). Ensure the house water supply is connected and the valve is fully open and not clogged. The water filter may need replacing (approximately every six months, when the indicator turns on, when the water dispenser output decreases, or when ice cubes are smaller than normal). Low water pressure or a kinked water supply line can also be the cause.

    Why is my LG LFX25991ST Refrigerator not dispensing ice?

      Your LG Refrigerator may not be dispensing ice if the doors are not closed completely. Check the ice bin for ice cubes clumping together and break them up. The delivery chute may be clogged with frost or ice fragments; remove the ice bin and clear the chute with a plastic utensil. Ensure the dispenser display is not locked by pressing and holding the Lock button for three seconds. Finally, ensure the ice bin is not empty and that the shutoff (arm/sensor) is not obstructed.

    Why is my LG LFX25991ST Refrigerator not dispensing water?
    • W
      woodwardmichaelAug 28, 2025
      Your LG Refrigerator may not dispense water if it is a new installation or the water line was recently connected; dispense 2.5 gallons of water to remove trapped air. Ensure the dispenser panel is not locked by pressing and holding the Lock button. Make sure the dispenser is set for water dispensing by pressing the Water button. Check that all refrigerator doors are properly closed. If the water filter was recently removed or replaced, dispense 2.5 gallons of water. Ensure the tubing connecting the refrigerator to the water supply is not kinked. If the problem persists, it may be necessary to contact a plumber.

    Why is food freezing in the refrigerator compartment of my LG LFX25991ST Refrigerator?
    • A
      Amy SmithAug 29, 2025
      Food may be freezing in your LG Refrigerator compartment if food with high water content is placed near an air vent; rearrange these items. Also, the refrigerator temperature control may be set incorrectly; adjust it one increment at a time. Lastly, the refrigerator should not be operated in temperatures below 55°F (13°C).

    • C
      Charles PattersonSep 1, 2025
      Frost or ice crystals can form on frozen food in your LG Refrigerator if the door is opened frequently or for long periods. Try to reduce how often and how long you open the door. Also, ensure that the door is closing properly.

    • J
      John JenkinsSep 4, 2025
      Your LG Refrigerator may be dispensing warm water if it was recently installed; allow 24 hours for the water storage tank to cool. If the dispenser has been used recently, the storage tank may be exhausted. If the dispenser has not been used for several hours, discard the first 10 oz. Ensure the refrigerator is connected to a cold water pipe.
