  Your LG Refrigerator may not be cooling due to several reasons. The refrigerator control might be set to OFF, so turn the control ON, referring to the Setting the Controls section for correct temperature settings. It's also possible the refrigerator is in the defrost cycle; wait 30 minutes after the cycle completes to see if the proper temperature is restored. If the refrigerator was recently installed, it can take up to 24 hours to reach the desired temperature. Finally, if the refrigerator was recently relocated, ensure it stood upright for 24 hours before connecting it to power.

What to do if my LG LFX25974ST is not dispensing ice?

  If your LG Refrigerator is not dispensing ice, ensure that all the refrigerator doors are completely closed. Check the ice bin for ice cubes clumping or sticking together and break them up if necessary. If the delivery chute is clogged with frost or ice fragments, remove the ice bin and clear the chute with a plastic utensil. Make sure the dispenser display is not locked by pressing and holding the Lock button for three seconds. Also, ensure the ice bin is not empty and that the shutoff (arm/sensor) is not obstructed.

What to do if food is freezing in my LG LFX25974ST compartment?

  jenniferpalmerAug 31, 2025
  If food is freezing in your LG Refrigerator compartment, it might be because food with high water content was placed near an air vent; rearrange these items away from the vents. The refrigerator temperature control may be set incorrectly; adjust the control one increment at a time and wait for the temperature to stabilize. The refrigerator may also be installed in a cold location; it should not be operated in temperatures below 55°F (13°C).

How do I fix LG LFX25974ST Refrigerator doors that won't close correctly or pop open?
- T
  Thomas McdonaldSep 6, 2025
  If your LG Refrigerator doors will not close correctly or pop open, it could be due to food packages blocking the door; rearrange the containers to clear the door and door shelves. Check if the ice bin, crisper cover, pans, shelves, door bins, or baskets are out of position; push bins all the way in and put crisper covers, pans, shelves, and baskets into their correct positions. If the doors were removed during product installation and not properly replaced. Ensure that the refrigerator is leveled properly.

Why does my LG Refrigerator ice have a bad taste or odor?
- C
  Corey CarpenterSep 8, 2025
  If the ice from your LG Refrigerator has a bad taste or odor, the water supply may contain minerals such as sulfur; consider installing a water filter. If the icemaker was recently installed, discard the first few batches of ice. If the ice has been stored for too long, throw it away and make a new supply. Improperly stored food in either compartment can also cause this issue, so rewrap the food. The interior of the refrigerator or the ice storage bin may need to be cleaned; ensure the bin is completely dry before reinstalling it.

How to fix interior moisture buildup in my LG LFX25974ST?
- D
  Dean HallSep 12, 2025
  Interior moisture buildup in your LG Refrigerator can be caused by several factors. Frequent or prolonged door openings can introduce moisture, so reduce how often and how long you open the doors. Ensure the doors are closing correctly. Humid weather can also contribute; maintaining a reasonable humidity level in your home can help. If the defrost cycle recently completed, wait 30 minutes for the temperature to stabilize. Improperly packaged food can also cause moisture; wipe containers dry and store food in sealed packaging.

Why is water dispensing warm from my LG Refrigerator?
- G
  Gene BrownSep 13, 2025
  If your LG Refrigerator is dispensing warm water, it may be because the refrigerator was recently installed; allow 24 hours for the water storage tank to cool completely. The dispenser may have been used recently, exhausting the storage tank, which has a capacity ranging from approximately 20 to 30 oz (570 to 850 cc), depending on the model. If the dispenser has not been used for several hours, discard the first 10 oz (280 cc). Ensure the refrigerator is connected to the cold water supply.

Why does the water from my LG LFX25974ST have a bad taste or odor?
- R
  Robert CamposSep 15, 2025
  If the water from your LG Refrigerator has a bad taste or odor, the water supply might contain minerals such as sulfur; consider installing a water filter. The water filter may also be exhausted, so replace it approximately every 6 months or when the water filter indicator turns on, when the water dispenser output decreases or when the ice cubes are smaller than normal. If the refrigerator was recently installed, dispense 2.5 gallons (9 liters) of water to remove trapped air and contaminants.
