Check to see if the compressor is running as well as well the Condesor fan. If they are, the compressor has failed. It's very common on LG fridges with the linear compressor. You can call LG, and they'll cover it under warranty. Due to a class action lawsuit, it's covered for 10 years. Labor is covered only up until 5 years, though. Keep in mind it can take a while to have to repaired.

March 4, 2021 our LG fridge is not 3 years old. Repeated no cooling events over past two months, lost food, and living out of coolers in garage. Life is Good -or so says LG.. Still no cooling after two technician visits, compressor replaced, recharged system - and OMG DON"T BUY AN LG FRIDGE. Technician was very responsive and took good care -but we've since learned of all the linear compressor problems, class action lawsuit, customer complaints, and LG (Life is Good) indifference to the consumer. Married 50 years we've moved 9 times , lived in three different states - and never owned such a piece of junk in ANY appliance. OMG DON'T BUY AN LG.

NO!! I purchased a French door refrigerator in November 2020 deliver and in stalled January 2021 and it stopped cooling 2 weeks later repair man said it was the compressor. My refrigerator was manufactured in July 2020. Still waiting on repairs.

Talk to your local appliance store about parts availability.

Condenser Coils are Dirty · If the refrigerator is not cold enough the condenser coils may be dirty. The condenser is like a radiator and must stay clean in order to dissipate the heat which was removed from the inside of the refrigerator. As the coils get dirtier the refrigerator becomes less efficient, which makes it work harder to cool down. If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the inside of the refrigerator to the proper temperature. · Evaporator Fan Motor · If the refrigerator is not cold enough, the evaporator fan motor might have failed. Every refrigerator has a set of coils called and evaporator. The refrigerator may have one or more evaporator fan motor(s) depending on the model and evaporator locations. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment. The freezer may still get cold. · Condenser Fan Motor · If the refrigerator is not cold enough there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back. Pull the refrigerator out from the wall and remove the access panel to access it. · Start Relay · If the refrigerator is not cold enough, the start relay may be defective. The start relay is a small device mounted to the side of the compressor. It provides power to the run winding along with the start winding for a split second at start-up to help get the compressor started. If the start relay is defective the compressor may run intermittently or not at all and the refrigerator will not get cold enough. The start relay should be replaced if defective. · Temperature Control Thermostat · If the refrigerator does not get cold enough the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem. · Start Capacitor · If the refrigerator isn't cold enough the compressor might be having difficulty starting. The start capacitor serves as a battery to give the compressor a little boost during start-up. If the start capacitor is burned out the compressor might not be able to start and run as often as it should. Test the start capacitor first with a capacitance meter, they don't fail often. If it's defective, replace it. · Thermistor · If the refrigerator is not cold enough the thermistor might be defective. The thermistor is a sensor which monitors the air temperature. It is connected to the control board. If the thermistor is defective the refrigerator does not cool or may cool continuously. · Temperature Control Board · If the refrigerator is not cold enough the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem. · Compressor · If the refrigerator is not cold enough, the compressor might be defective. The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. There are several other components which are more likely to be defective if the compressor doesn't work. If the compressor itself is defective a licensed professional will need to replace it. · Main Control Board · If the refrigerator is not cold enough the main control board might be defective. This is not common. Check the defrost system, cooling fans, and cooling controls first. · UPDATE 3/3/16 · asking additional question on one with an accepted answer is almost a sure way for it not to be seen. If the answer that's accepted does not answer your problem, ask a new question with your specific problem and symptoms. · UPDATE 7/13,19 · Thanks to LKT for making us aware of this · A class action lawsuit claims there is a “latent defect" with LG linear compressors which causes them to prematurely fail. "Despite its knowledge of the compressor defect, sold and continues to sell the LG refrigerators without alerting purchasers to the problem." ... declined to elaborate. · https://www.girardsharp.com/work-pending... · Check the LG refrigerator not cooling page for updates as well.
