LG refrigerator makes a lot of noise or hum for various reasons. It can occur as a result of installation on an uneven surface, but there can also be serious breakdowns of the internal parts of the refrigerator. For example, failure of the fan, starting relay, compressor, clogging in the capillary system, etc. It is possible to find out the exact cause of the breakdown only as a result of diagnostics.  

Incorrect installation

  For any LG refrigerator, regardless of the model, the following rules apply:   – The distance between the rear wall of the device and the wall of the room – at least 5 cm. – There should be a distance of 10 cm between the appliance and pieces of furniture. – From the top of the refrigerator to the ceiling – at least 10 cm.   If these requirements are not complied with, the vibrations from the work of the internal components cause beating. To solve the problem, you need to move the unit away from the walls and other objects, sometimes it is necessary to move it to another place.   Another possible option is the installation on an uneven surface. Because this can shift the compressor, and there is vibration. This is especially common when the unit is placed on flooring that has chips or potholes, without adjusting the height of the feet. To solve the problem, you will need to have the unit leveled by aligning it. Most LG refrigerators are provided with threaded feet, their height can be changed manually. If the difference is too large, it makes sense to do the work of leveling the surface even before installing and connecting the appliances.  

Not enough air in the compressor

  Compressor cooling may be uneven or too weak, as a result, the unit overheats and starts to rattle. The problem can occur with both a new refrigerator and an old one. The main causes are:   – Too little clearance between the back panel and the wall. – Insufficient distance between the unit and other objects in the room. – Large amounts of dust accumulated on the surface of the rear wall of the refrigerator.   It is necessary to move the refrigerator away from the walls to keep the required distance, as well as to take care that there are no pieces of upholstered furniture (armchairs, sofas, poufs, etc.) nearby. Dust should be cleaned regularly, without waiting for the refrigerator to become loud again; the minimum frequency of the procedure is once a month. In addition, it is recommended to increase the distance between the bottom of the device and the floor: this can be done by exposing the legs to the maximum length or by placing special supports. This is especially relevant for small kitchens, where no powerful ventilation system is provided, and the movement of air flows is difficult.  

The compressor is loose

  In the course of operation, the fastening of the motor can become deformed, this is especially common with older models, where metal springs are installed. With prolonged operation, metal fatigue accumulates, spring elements become weaker, and compression force decreases. As a result, the compressor begins to touch the cooling system tubes, internal surfaces of the housing, and other parts, and as a result of this, there are noises.   Trouble can also occur with a modern LG refrigerator, equipped with a rubber sealing element: such a part is more prone to mechanical damage, and it can break. In addition, as a result of wear and tear, the seal made of polymeric material loses elasticity, and loosens as a result of constant load and vibration, as a result, the position of the compressor changes.   Regardless of what fasteners are used in the design, it will be necessary to replace the worn parts. Doing this work yourself is not recommended, because it requires special tools and skills in repairing appliances. If upon inspection it turns out that the problem cannot be fixed by leveling the refrigerator and wiping off the dust, it makes sense to go to the service for professional diagnostics.
