With the improvement of living standards, refrigerators have become an indispensable part of family life. As one of the important electrical appliances in family life, the refrigerator not only provides us with cold drinks and cold food, but also can store some medicines, cosmetics and other items that need to be stored at low temperature.

But what to do when you find your LG refrigerator not cooling? In this article, we will introduce 13 reasons why your LG refrigerator is not cooling and how to deal with it. If other brands of refrigerators have the same problems, you can also refer to the following solutions

1. 13 Reasons Why Your LG Refrigerator Not Cooling and How to Fix It

If your LG refrigerator has just been installed, please note that it usually takes more than 3-4 hours for a new LG refrigerator to produce cold air after it is powered on, please wait patiently.

If your LG refrigerator is not new and does not cool suddenly, it may be caused by the following reasons.

1.1 Power Failure

Sometimes it is not a refrigerator use problem or a quality problem, it may be a power problem. If the power plug of the LG refrigerator is not fully in contact with the socket, or the household voltage is too low, the LG refrigerator compressor cannot be started normally.

Solution: Check whether the power connection is normal. Open the LG refrigerator door and observe whether the lighting in the refrigerator is on or use an electroprobe to test whether the socket has electricity.

In addition, if the inspection result is that the voltage is too low, it is recommended to equip the refrigerator with a voltage stabilizer.

1.2 Compressor Failure

If the power connection is normal, listen to whether the LG refrigerator compressor is working. The compressor will make a slight vibrating sound when it is working normally. If you feel the vibration of the compressor with your hands, you should be careful not to burn yourself. Because the temperature of the compressor is 40-50°C in winter and 80-90°C in summer.

Solution: If the LG refrigerator compressor breaks down, ask professionals to disassemble the refrigerator for detailed inspection. It is not recommended for users themselves to dismantle the machine for maintenance.

1.3 Refrigerant Leak

If the LG refrigerator compressor can work, check whether there is refrigerant leakage in the refrigeration system. Let the refrigerator run for a few minutes and unplug it, and listen carefully for whether there is the sound of liquid flowing in the copper pipe. If not, it means that the refrigerant in the system has leaked.

Solution: If the refrigerant leaks. Let the technician repair the leak and refill the refrigerant.

1.4 Start Relay Damaged

When the LG refrigerator compressor is started, it needs a start relay to assist the start. If the device is damaged, the LG refrigerator compressor cannot be started normally.

Solution: Under normal circumstances, if the LG refrigerator compressor cannot be started after the refrigerator is powered on and you can hear the buzzing sound of the compressor, it means that the start relay is faulty. At this time, the fault can be repaired by replacing the start relay.

1.5 Capillary Tube Blockage

The capillary tube plays an extremely important role in the refrigeration process of the refrigerator. It can change the low-temperature and high-pressure state of the refrigerant into a low-temperature and low-pressure state. The refrigerant absorbs heat instantly after entering the evaporator through the capillary tube, thereby achieving the cooling effect.

Solution: If the capillary tube is blocked, the refrigerant will lose the channel for transferring the medium, and the refrigerator will lose its cooling capacity. At this time, it is necessary to disassemble the LG refrigerator, remove the capillary tube, clean the blockage inside it, and then put it back in place to repair the fault.

Note that ordinary users do not have the working conditions to remove and unclog the capillary tube, so this fault should be repaired by professionals.

1.6 Solenoid Valve Failure

The solenoid valve is mainly used to control the flow direction of the refrigerant. If the solenoid valve fails, the refrigerant will not circulate normally, which will cause the LG refrigerator not cooling.

Solution: Just replace the solenoid valve.

1.7 Broken Refrigerator Door gasket

If the LG refrigerator door gasket is damaged, the refrigerator will lose or reduce the cooling effect, and at the same time, the LG refrigerator compressor will be in working condition for a long time.

Solution: At this time, you need to check the door seals of the LG refrigerator one by one, and replace the broken ones to solve the problem.

1.8 Refrigerator Filter Screen Clogged

The function of the filter is to adsorb impurities, but after a long time, a large amount of impurities on the filter will increase the operating pressure of the LG refrigerator compressor.

Solution: The filter screen should be cleaned in time every once in a while.

1.9 Blocked Air Outlet

There is too much food stored in the refrigerator, which blocks the air outlet, causing the internal temperature of the LG refrigerator to continue to rise, and the cooling effect to deteriorate.

Solution: The food in the refrigerator should not be stored too much to ensure the smooth air outlet.

1.10 Thermostat Failure

If the contacts of the thermostat switch stick together, and the action fails, it will cause the circuit to be in the on state for a long time, making the LG refrigerator not cooling.

Solution: At this time, you should find a technician to remove and repair the thermostat or replace it with a new one.

1.11 Fan Failure

When the fan fails and does not work, the cooling effect of the LG refrigerator will be poor. The refrigerator cannot dissipate heat, and the heat will be concentrated, causing the temperature to rise, and naturally the cooling effect of the refrigerator will be poor.

Solution: If it is confirmed that the fan is faulty, find a technician to fix it in time.

1.12 Dirty Condenser Coils

After a long time, dust and oil are easy to accumulate on the LG refrigerator condenser, resulting in poor heat dissipation.

Solution: It should be cleaned regularly to remove dust and oil.

In addition, when the LG refrigerator is installed, if no room is reserved between the refrigerator and the walls, it will also lead to poor heat dissipation and affect the cooling effect.

1.13 Control Circuit Board Failure

The LG refrigerator control circuit board is mainly used to control the operation of the refrigerator. If the control circuit board fails, it will mainly cause the refrigerator not working, not cooling and other faults.

Solution: It is necessary to ask someone professional to check and replace it in time.

2. Conclusion

When the LG refrigerator does not cool, it is not recommended to dismantle the refrigerator for maintenance by individuals. If conditions permit, please ask professionals to come to the door for inspection and maintenance, otherwise it may cause greater damage to the machine due to personal disassembly and assembly.
