  Peter WeberAug 16, 2025
  If your LG Refrigerator isn't working, there are several possible causes. First, ensure the power supply cord is firmly plugged into a live outlet with the correct voltage. Also, check your household fuse or circuit breaker and replace the fuse or reset the breaker if needed. The refrigerator control might be set to the OFF position, so refer to the Setting the Controls section on page 15. Finally, the refrigerator may be in the defrost cycle; wait about 30 minutes for it to end.

  If the ice cubes produced by your LG Refrigerator's icemaker are too small, check if a smaller cube size level is selected and choose a larger cube size. Also, the water shutoff valve connecting the refrigerator to the water line may be clogged; call a plumber to clear the valve.

Why does the compressor motor in my LG LRFC21755ST seem to run too much?
- K
  Karen DawsonAug 22, 2025
  Several factors can cause the compressor motor to run more than expected. If you replaced an older model, modern refrigerators with more storage space require more operating time. Warmer room temperatures will cause the motor to run longer. Frequent door openings or adding a large amount of food can also increase running time; try to get everything you need at once, keep food organized, and close the door quickly. If the refrigerator was recently plugged in, it can take up to 24 hours to cool completely. Ensure the refrigerator control is correctly set for the surrounding conditions. Make sure the doors are fully closed and clean the condenser coils.

Why won't the doors on my LG Refrigerator close completely?
- K
  Kevin OlsonAug 26, 2025
  If the doors on your LG Refrigerator won't close completely, several issues could be the cause. The refrigerator might not be level. Food packages may be blocking the door. The ice bin, crisper cover, pans, shelves, door bins, or baskets could be out of position; make sure bins are pushed all the way in and other components are correctly placed. Also, the gaskets might be sticking, so clean them and the surfaces they touch. Additionally, ensure the refrigerator is stable and level. If the doors were removed during installation, they may not have been properly replaced.

Why is the temperature too warm or is there moisture inside my LG LRFC21755ST Refrigerator?
- C
  Christopher PittsAug 27, 2025
  Several factors can cause a warm temperature or moisture buildup inside your LG Refrigerator. Blocked air vents can restrict airflow, so move any packages obstructing them. Frequent door openings allow warm, humid air to enter. Ensure the control is correctly set for the surrounding conditions. Adding a large amount of food warms the refrigerator. Incorrectly packaged food can contribute to the issue, so wrap food tightly and wipe off damp containers. Make sure the doors are closing completely. Humid weather introduces moisture when the doors are opened. Droplets on the back wall are normal after a self-defrost cycle.

- D

  Frost or ice crystals on frozen food in your LG Refrigerator can be caused by the door not closing properly. Also, frequent door openings allow warm, humid air into the freezer, resulting in frost.

Why is there water in the defrost drain pan of my LG LRFC21755ST Refrigerator?
- K
  Kathy HoustonSep 5, 2025
  If there's water in the defrost drain pan of your LG Refrigerator, it's likely because the refrigerator is defrosting; the water will evaporate. If it's more humid than normal, expect the water in the defrost pan to take longer to evaporate.

How to fix the lights if they don't work in my LG LRFC21755ST?
- S
  Susan ThompsonSep 7, 2025
  If the lights in your LG Refrigerator aren't working, first ensure the power supply cord is firmly plugged into a live outlet. If that's not the issue, turn the refrigerator control to the OFF position and unplug the refrigerator. Gently remove the bulb and reinsert it. Then, plug the refrigerator back in and reset the control. If the bulb is burned out, replace it with an appliance bulb of the same wattage, size, and shape from your local hardware store.

Why does the ice from my LG LRFC21755ST have an off-taste or odor?
- R
  Russell FloresSep 10, 2025
  If the ice from your LG Refrigerator has an off-taste or odor, it could be due to several reasons. If the icemaker was recently installed, discard the first few batches of ice. Ice stored for too long can also develop off-flavors, so throw away old ice. Food not wrapped tightly in the ice compartment can cause odors to migrate to the ice, so rewrap foods properly. The water supply may contain minerals like sulfur, requiring a filter. The interior of the refrigerator or the ice storage bin might need cleaning; empty and wash the bin and discard old cubes.
