Chosen Solution
Hurricane Irma passed and my new LG refrigerator has stopped cooling. What could be the problem?
The first thing I would do is look around the neighborhood tonight and see if there are any lights on. Did it get knocked over or flooded out or receive an electrical surge. Cause 1 Condenser Coils are Dirty The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won’t dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty—if the condenser coils are dirty, clean them. Cause 2 Condenser Fan Motor The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won’t cool properly. To determine if the fan motor is defective, first check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If no obstructions are present and the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the condenser fan motor does not have continuity, replace it. Cause 3 Evaporator Fan Motor The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor. If none of that works, you can find a few more solutions to try on the LG refrigerator not cooling wiki.
If you open the door and the lights don’t come on you need to check voltage and polarity at your power source. If you have lights the display should also be lite. Adjust your temperatures to 0f in freezer and 36f in fresh food. Some LGs have to be turned on after a power failure. Usually the sequence of buttons to push at the same time is on the display or in the owners manual. Next, pull out unit and remove the back access panel carefully. Is the fan next to the compressor running? If not, remove the access panel above the compressor. 3 screws hold it in place. BE CAREFUL this is the main control board and at some connections there is 300 + volts. You want to look for a blinking light. Count the number of blinks. If no blinking light, unplug the refrigerator. There is 1 sometimes 2 fuses located on the board. Check with a meter for ohms/resistance. You can gently pull the fuses out. They are about an inch long, round glass fuse. You can visually look for the broken wire too if you don’t have a meter. The fuses have their size on them. Most hardware stores carry them.
Brndn2263-did you notice if the coils by the fan were dirty? Dirty coils restrict air flow. Compressor gets hot and nothing works right. I’d suggest to unplug it, let compressor cool then clean the couls good with a vacuum or coil brush. Clean from back and the front. Plug it in and hope it cools. It can take up to 48 hrs for the refer to reach temperature. Putting water, sodas etc in it will help it get cold faster. Bowls of water in freezer help n when they freeze you can put everything back in. The ice maker will take 2-3 days before it drops ice. Lg has a 7-10 yr”parts only”’warranty on the sealed system. If it doesn’t cool after 48 hrs and the compressor gets hot again, I’d have to say the problem is in the sealed system. A refrigerant leak and/or a restriction in the systems can cause the compressor to get hot. Dirty coils can cause a leak and a restriction. Very important to clean coils 1x a yr. more if you have pets. I wouldn’t mention you cleaned the coils. The tech might think you cleaned them cuz you knew they were coming. Dirty coils voids any warranty. The manufacturers consider it abuse. LG should have plenty of Certified technicians in the DFW area. Unfortunately, I’m an 8 hr drive from Dallas. If you don’t mind posting the outcome, I’d appreciate it. Take care
