Why is my LG GM-U552S not cooling?

  Renee KnightAug 18, 2025
  If your LG Refrigerator isn't cooling, ensure it's firmly plugged into a working outlet with the correct voltage. Also, check your household fuse or circuit breaker and replace or reset if necessary. The issue might also be that the refrigerator control is in the OFF position, so check the control settings. If the refrigerator is in defrost cycle, wait about 30 minutes for it to end. Finally, check if the refrigerator is in DEMO mode, indicated by the OFF light being illuminated. To disable Demo Mode, press the TEMPERATURE ADJUST button until you set the desire temperature level. When demo mode is deactivated, the OFF light will turn off.

Why is my LG Refrigerator icemaker not making ice?
- A
  Anthony WashingtonAug 21, 2025
  If your LG refrigerator's icemaker isn't making enough ice, give it 12 to 24 hours after installation to start producing ice, and 72 hours for full production. Ensure the refrigerator is connected to a water supply and the shutoff valve is fully open. Check for kinks in the water line and straighten it if necessary. Also, verify that the icemaker is turned on. Make sure nothing is blocking the ice-detecting sensor. The freezer temperature should be at 0°F for normal ice production. Avoid opening the doors too often. If the doors are not properly closed, ice production will be affected.

  If there is interior moisture buildup or the temperature in your LG Refrigerator is too warm, ensure the air vents aren't blocked. Avoid opening the doors too often. Check that the control is correctly set for the conditions. Remember that adding a large amount of food can warm the refrigerator. Make sure food is correctly packaged. Also, ensure the doors are closing completely. Note that humid weather can introduce moisture, and droplets may form after an automatic defrost cycle.

Why does the compressor on my LG GM-U552S run so much?
- D
  David ChangAug 27, 2025
  If your LG Refrigerator's compressor seems to run too much, remember that modern refrigerators require more operating time but use less energy. The compressor will run longer in warmer conditions. Adding food and opening the door warms the refrigerator, requiring the compressor to run longer. The refrigerator will take up to 24 hours to cool completely after being plugged in. Ensure the refrigerator control is set correctly. Make sure the doors are closed completely. A dirty back cover can also make the motor work harder, so clean it.

  If you notice frost or ice crystals on frozen food in your LG Refrigerator, it might be due to the door not closing properly or the door being opened too often, allowing warm, humid air to enter the freezer.

  If your LG Refrigerator lights do not work, make sure the power supply cord is plugged into a live outlet with proper voltage. If an LED light has malfunctioned, unplug the refrigerator or turn off power at the circuit breaker before proceeding to replace the LED. Note that LED service should only be performed by a qualified technician.

Why are the doors on my LG Refrigerator hard to open?
- C
  Cody ThompsonSep 3, 2025
  If the doors of your LG Refrigerator are difficult to open, the gaskets might be dirty or sticky. Clean the gaskets and the surfaces they touch, and then apply a thin coat of appliance polish or kitchen wax. Also, if the door is reopened shortly after being opened, it can create a vacuum. Wait one minute to allow the air pressure to equalize.

Why does the ice from my LG GM-U552S taste bad?
- J
  jessicabarronSep 6, 2025
  If your LG Refrigerator has ice with a bad taste or odor, discard the first few batches of ice if the icemaker was recently installed. Throw away old ice that has been stored for too long and make a new supply. Rewrap foods tightly in both compartments, as odors may migrate to the ice if food is not wrapped properly. If your water supply contains minerals, install a water filter. Clean the interior of the refrigerator and the ice storage bin.

Why is food freezing in my LG Refrigerator compartment?
- D
  Daisy WilliamsSep 8, 2025
  If you find frozen food in the refrigerator compartment of your LG Refrigerator, the temperature control might be set too cold. Adjust it to a warmer setting. If the refrigerator is installed in a cold location, food can freeze when the room temperature is below 41°F (5°C). Also, food with a high water content placed too close to the cold air discharge vent can freeze.
