Why does my LG Refrigerator compressor motor stay on too long?
- M
  Mark ChangSep 3, 2025
  Several factors can cause the LG Refrigerator's compressor motor to run longer than expected. If you have a newer model with a larger storage capacity, it naturally requires longer operation periods. Warmer room temperatures will also cause the motor to run more frequently, potentially between 40% to 80% of the time. Frequent door openings or storing a large amount of food can warm the refrigerator, requiring the motor to run longer to cool it back down. Ensure doors are closing properly and clean the condenser pipes.

  Lisa WillisSep 2, 2025
  If the light in your LG Refrigerator won’t turn on, check if the light bulbs are loose. Unplug the refrigerator, unscrew the light bulb, and screw it in again. If that doesn't work, the light bulb may have gone bad. Unplug the refrigerator before changing the light bulb and replace it with a 40-watt bulb.

Why is there water in the draining bin of my LG LFC20770SB Refrigerator?
- R
  Rebecca LeeAug 31, 2025
  The presence of water in the draining bin of your LG Refrigerator is normal during the defrosting cycle, as the water will evaporate. In more humid conditions, it might take longer for the water to evaporate, which is typical in hot and humid weather.

  If the temperature in your LG Refrigerator is too high or there's humidity inside, check if the air vents are blocked and clear any obstructions. Avoid frequent door openings to prevent warm, humid air from entering. Allow 24 hours for temperature stabilization after adjusting the refrigerator control. Ensure food is properly wrapped and bins are dry to minimize humidity. Also, it’s normal that some water props get formed after the defrosting cycle is completed.

Why is there ice on the food in my LG LFC20770SB?

  Christopher HughesAug 28, 2025
  Ice on food in your LG Refrigerator is often due to the door not being closed completely. Also, opening the door frequently lets warm, humid air into the freezer, which results in frost.

  Jennifer BurnettAug 27, 2025
  If your LG Refrigerator isn't turning on, a fuse might have blown, or the circuit could be faulty. Replace the fuse or reset the circuit breaker. Also, ensure the refrigerator is firmly plugged into a working outlet with the correct voltage. If it still doesn't turn on, wait about 30 minutes to allow the defrost cycle to complete.

  If your LG Refrigerator's ice maker isn't producing ice or the ice cubes are freezing too slowly, wait 24 hours after hook-up for ice production. Also, make sure that the door is not left open.
