Why is the cooling system in my LG GF-5D712SL running too much?

  If your LG Refrigerator cooling system runs too much, it could be due to several reasons. Modern refrigerators require more operating time but use less energy. If recently plugged in, it can take up to 24 hours to cool completely. Frequent door openings or adding a large amount of food warms the refrigerator, requiring the compressor to run longer. Ensure the doors are closed completely and that the refrigerator isn't installed in a hot location. Clean the condenser cover and vents with a vacuum cleaner attachment after disconnecting the mains.

Why is my LG GF-5D712SL icemaker not making enough ice?
- N
  Nicole WaltersAug 23, 2025
  If the icemaker in your LG refrigerator isn't making enough ice, it could be due to several factors. The demand might exceed the ice storage capacity, as the icemaker produces about 50-80 cubes in 24 hours. Ensure the house water supply is connected, the valve is fully open, and not clogged. Replace the water filter every six months or when the indicator turns on. Low water pressure or a kinked water supply line can also be the cause. Reverse Osmosis filtration system can also reduce the water pressure.

  If the LG Refrigerator is not dispensing ice, ensure all doors are completely closed. Infrequent use can cause ice cubes to stick together; break them up if needed. Clear the delivery chute of frost or ice fragments using a plastic utensil, and try dispensing cubed ice to prevent buildup. Check if the dispenser display is locked and unlock it by pressing and holding the Lock button for three seconds. Ensure the ice bin isn't empty, which can take up to 24 hours to fill after installation.

  If your LG Refrigerator icemaker is not making ice, it may take up to 24 hours after installation or connection for ice production to begin. Ensure the icemaker is turned on using the Ice On/Off button. Verify the refrigerator is connected to a water supply and the shutoff valve is open. Check that the icemaker shutoff arm or sensor is not obstructed. Reverse osmosis water filtration systems can reduce water pressure, causing issues.

  Stephanie ReidAug 27, 2025
  Your LG Refrigerator might not be cooling because the display control is set to OFF. Cancel the OFF mode to start the unit. It could also be in Display mode, or the refrigerator might be in the defrost cycle, during which the temperature may rise slightly for about 40 minutes. If the refrigerator was recently installed or relocated, it can take up to 24 hours to reach the desired temperature; if relocated, let it stand upright for 24 hours before connecting to power.

What to do if my LG Refrigerator is not dispensing water?
- A
  Andrea MckinneyAug 29, 2025
  If your LG Refrigerator isn't dispensing water, it could be due to a few reasons. If it's a new installation or the water line was recently connected, dispense 2.5 gallons of water to remove trapped air. Make sure the dispenser panel isn't locked by pressing and holding the Lock button for three seconds, and ensure the dispenser is set to water dispensing by pressing the Water button. Check that the refrigerator doors are fully closed. If the water filter was recently replaced, dispense 2.5 gallons of water. Also, inspect the tubing for kinks and ensure the house water supply is connected and the valve is fully open.

Why does the cooling system in my LG GF-5D712SL Refrigerator run so much?
- J
  Joshua KleinSep 18, 2025
  The cooling system in your LG Refrigerator might run more than expected because modern refrigerators require more operating time due to efficient technology. If recently plugged in, it can take up to 24 hours to cool completely. Frequent door openings or adding a large amount of food or hot food can also cause this. Ensure doors are closed completely and the refrigerator isn't in a hot location (above 43°C). Also, check if the condenser/back cover is clogged and clean it with a vacuum cleaner.

How to prevent interior moisture buildup in my LG Refrigerator?
- J
  John DavisSep 12, 2025
  If you notice interior moisture buildup in your LG Refrigerator, it could be due to doors being opened frequently or for long periods. Humid weather can also introduce moisture when the doors are opened. Make sure to maintain a reasonable humidity level in your home. Ensure food is packaged correctly in sealed containers and wipe containers dry. If a defrost cycle has recently completed, wait 40 minutes.

Why is my LG GF-5D712SL section too warm?
- J
  John Byrd MDSep 5, 2025
  If your LG Refrigerator section is too warm, it could be because it was recently installed, and it can take up to 24 hours to reach the desired temperature. Check if the air vents are blocked and rearrange items to allow airflow. Frequent or prolonged door openings can also cause this, so reduce these. Ensure the unit isn't in a hot location (above 43°C). If you've added a large amount of food or hot food, allow hot food to cool before refrigerating. Make sure the doors are closing correctly, the temperature control is properly set, and the defrost cycle has completed (wait 40 minutes after).
