LG fridges combine good functionality with practicality and reliability, but they do break down from time to time. One of the most typical signs of a problem is the appearance of extraneous noises or increased noise when the unit is in operation.

 

Excessive tightening of the transport screws. If a new refrigerator starts making noise immediately after installation, it is essential to check that they have been removed. The transport screws must be unscrewed carefully so as not to damage the threads.

 

The enclosure is warped if the appliance is standing on an uneven surface.

Pipes are clogged with refrigerant, which puts an increased load on the compressor.

Damage to the fan.

 

Apart from the hum, other noises such as clicking, gurgling, squeaking, humming, or grinding may occur during operation; the cause must be diagnosed. It is important to bear in mind that at the first start-up the motor accelerates the freon and works at an increased load, so a loud buzzing noise is perfectly normal and there is no point in contacting a shop or service center in such a case. If the noise continues during operation, it is most likely a defect.

 

Incorrect installation

The following rules apply to any LG refrigerator irrespective of the model:

 

A distance of at least 5 cm between the rear wall of the unit and the wall of the room.

There must be a distance of at least 10 cm between the appliance and pieces of furniture.

At least 10 cm from the top of the refrigerator to the ceiling.

If these requirements are not complied with, vibrations from the internal components cause the appliance to vibrate. 

Another possibility is installed on an uneven surface. This can dislocate the compressor and cause vibration. This is particularly common when the unit is placed on a floor with chipped or potholed floors and without height adjustment of the feet. To solve the problem, you will need to have the appliance leveled. Most LG refrigerators are fitted with threaded feet and the height can be adjusted manually.

 

Insufficient air supply for the compressor

The cooling of the compressor can be uneven or too weak, as a result, the assembly overheats and starts to rattle. The problem can occur with both a new and an old refrigerator. 

 

The compressor fixing is loose

During use, the motor mount can become deformed, this is especially the case with older models where metal springs are fitted. Over time, metal fatigue builds up, the spring elements weaken and compression force decreases. As a result, the compressor starts to touch the cooling system tubes, the internal surfaces of the housing, and other parts, and noises occur as a result.

 

Fan malfunctions

As a rule, failures of this node occur in LG refrigerator models equipped with the “No Frost” system. The fan is used to dehumidify the internal capacity of the chamber and cool the evaporative equipment, some models provide two fans – for the freezer and refrigerator compartment respectively. It should be noted that the operation of the refrigerator with two fans will be higher than that of the model with a single unit.
