Why is my refrigerator not cooling?

Expand All

• Was the Refrigerator Installed in the Past 24 hours?

  The unit must be allowed to run for at least 24 hours for the internal temperature to stabilize. Also, if the refrigerator was filled with food and drink when installed, it will require longer than 24 hours.

  
  

• Is There An Error Code Displayed?

  This could indicate problems with frost buildup or other issues. Find out what the code means at Error Codes – Refrigerator.

  
  

• Were Hot Items Added To the Unit?

  Adding hot food to the compartment will temporarily warm the unit, requiring it to run longer to bring the temperature back down. Adding many food items at once can have the same effect.

  
  

• Are the Doors Being Opened Frequently?

  The unit will not be able to maintain a stable temperature regardless of the setting if the doors are opened too frequently.

  
  

• Are The Frozen Items Hard or Soft?

  If the frozen items are hard, note that the refrigerator goes through an auto defrost cycle as part of normal performance to prevent ice or frost buildup. The defrost cycle causes the temperature to rise, and the compressor does not run. Once defrosting is complete the refrigerator returns to normal temperature.

  
  

• What is the Refrigerator Temperature Set To?

  The recommended temperature settings are 37° Fahrenheit for the refrigerator, and 0° Fahrenheit for the freezer. If additional cooling is required, lower the temperature a few degrees. Unplug the refrigerator or turn off the circuit breaker for at least 10 seconds. Then plug the power cord back into the outlet or turn the circuit breaker back on.

  
  

• Are Food Items Blocking Air Flow?

  Too much food or food placed in front of the vents can block the air and disturb cold air circulation. Rearrange the food to ensure good airflow.

  
  

• Check and Clean Door Gaskets

  Make sure all sides of the door are closed without any gaps, that no food items are keeping the door from closing fully, and that the door gasket is not compressed anywhere. If so, use only warm water and mild detergent to clean the gasket, and gently pull out any compressed part. If the gasket has any wrinkles, it can be straightened by blowing hot air from a hair dryer into the creases.

  
  

• Check Placement

  There should be at least two inches between the back of the refrigerator and the wall for efficient air circulation.

  
  

• Check Condenser Cover Panel

  Dust can block the holes in the panel, reducing the ventilation efficiency of the condenser. Use a vacuum cleaner with a brush or crevice attachment to clean the condenser cover and vents. DO NOT REMOVE THE PANEL.

  
  

• Are the Doors Aligned Properly?

  Doors that are not aligned properly can create problems with gasket sealing. Refer to the owner’s manual, or watch How To Level Your LG Refrigerator for more information on leveling.

  
  

• Is the Unit Tilted Backwards?

  This can affect the gasket seal, causing the doors to have slight gaps. Adjust the leveling feet at the bottom front of the refrigerator to tilt the unit slightly toward the back.

  
  

• Is Demo Mode Turned OFF?

  To deactivate the demo mode on models from 2019 to the present, press the Refrigerator and Ice Plus key simultaneously, then while holding the Refrigerator button, tap the Ice Plus key three times.

  For models from 2018 and prior, press and hold the Refrigerator and Ice Plus keys simultaneously for five seconds.

  
  

• Is The Left Door Metal Flap Folded Out?

  This flap is what the right door presses against to create a seal. At the top of the flap is a small plastic piece that fits into a track at the top middle of both doors. Make sure both doors are aligned at the top, or slightly increase the height of the left door so that the flap contacts the track and closes properly.
