Why is my LG Refrigerator icemaker not working?

  markparksNov 25, 2025
  Several factors can cause your LG refrigerator's icemaker to stop producing ice or produce insufficient ice. First, if it's a new installation, allow 12-24 hours for ice production to begin and 72 hours for full production. Ensure the refrigerator is connected to a water supply and the shutoff valve is fully open. Check for kinks in the water line. Make sure the icemaker is turned on using the ON/OFF switch. Also, verify that the freezer temperature is set to the recommended 0°F. Additionally, obstructions on the ice-detecting sensor can interrupt ice production, so ensure the sensor area is clean. Frequent door openings can also affect ice production. If doors are not closing properly, see “Doors will not close completely” in the Troubleshooting section for more information. Reverse osmos...

How to fix LG Refrigerator icemaker that is not producing ice?

  Jessica AnthonyAug 25, 2025
  If the icemaker isn't producing ice, wait 12 to 24 hours after installation for ice production to begin, and 72 hours for full production. Ensure the refrigerator is connected to a water supply and the supply valve is fully open. Reverse osmosis water filtration systems can reduce water pressure, so check the Water Pressure section. Straighten any kinks in the water source line. The icemaker produces about 95 cubes in 24 hours. Confirm the icemaker is turned ON. Clear any foreign substances or frost from the ice-detecting sensor. The freezer temperature should be 0°F. Avoid opening the doors too often, and ensure they close properly.

Why is my LG LTCS20220 Refrigerator not cooling?

  Luke PrinceAug 26, 2025
  Your LG Refrigerator may not be cooling due to several reasons. It could be as simple as the power cord being unplugged; ensure it's firmly plugged into a working outlet. A blown fuse or tripped circuit breaker could also be the culprit; replace the fuse or reset the breaker. Also, check if the refrigerator is in Demo Mode, indicated by the OFF light being illuminated; to disable it, press the Temperature Adjust button until you set the desired temperature level. If it is in the defrost cycle, wait about 30 minutes for it to end. Finally, the refrigerator control might be set to the OFF position; check the Setting the Controls section.

Why does my LG LTCS20220 Refrigerator have frost or ice crystals on frozen food?
- J

  This issue can arise if the door is not closing properly. Also, frequent door openings allow warm, humid air into the freezer, leading to frost formation.

Why do lights not work in my LG LTCS20220 Refrigerator?

  Joan JonesAug 29, 2025
  If the lights aren't working, first ensure the power supply cord is firmly plugged into a live outlet with proper voltage. If an LED light has malfunctioned, unplug the refrigerator or turn off power at the circuit breaker or fuse box before replacing it. Note that LED interior lighting service should only be performed by a qualified technician.

Why does my LG LTCS20220 Refrigerator compressor run so much?
- R
  Ricky NicholsSep 17, 2025
  Several factors can cause your LG refrigerator's compressor to run more than expected. Modern refrigerators are more efficient but require more operating time than older models. Warmer room temperatures will cause the compressor to run longer; at normal room temperature (70°F) expect your compressor to run about 40% to 80% of the time. Frequent door openings or adding a large amount of food warms the refrigerator, requiring the compressor to work longer to cool it down. It can take up to 24 hours to cool completely after being plugged in. Ensure the refrigerator control is correctly set for the surrounding conditions. Make sure the doors are closed completely. A dirty back cover prevents air transfer, making the motor work harder; clean the back cover.

Why is my LG Refrigerator temperature too warm or has interior moisture buildup?
- T
  Theresa HillSep 14, 2025
  Several factors can cause this. Blocked air vents restrict airflow, so move any packages obstructing them. Frequent door openings warm the refrigerator, so try to get everything you need at once. Make sure the control is correctly set for the surrounding conditions. Adding a large amount of food can also warm the refrigerator. Ensure food is packaged correctly and wipe off damp containers. Also, make sure the doors are closing completely. Humid weather can introduce moisture, and droplets may form on the interior back wall after an automatic defrost cycle.

Why does my LG LTCS20220 ice have a bad taste or odor?
- D
  Dr. Stephanie Rodgers DDSSep 15, 2025
  If the ice has a bad taste or odor, discard the first few batches after icemaker installation. Throw away old ice and make a new supply. Ensure food is tightly wrapped in both compartments to prevent odor migration. If the water supply contains minerals like sulfur, consider installing a water filter. Also, clean the interior of the refrigerator and the ice storage bin, discarding old cubes.

Why is there frost on food in my LG LTCS20220 Refrigerator?
- S
  Sheila WagnerSep 7, 2025
  Frost or ice crystals on frozen food in your LG refrigerator can be due to the door not closing properly. It can also happen if the door is opened often, allowing warm, humid air into the freezer, which results in frost.
