Buying a new refrigerator is always a joyful event, which, however, is accompanied by serious physical work and technical nuances that require attention. One of the most critical points that many owners of household appliances forget about LGis the correct removal of the fixing elements that ensure the safety of the compressor during transportation.
Shipping bolts are special fasteners that rigidly fix the moving parts of the compressor to the frame of the unit, preventing them from damage from shock and vibration during delivery. If you do not know where the transport bolts are in the refrigerator LGand leave them after installation, this can lead to increased noise, vibration and, in the worst case, damage to the motor.
In this article we will analyze in detail the location of these elements on different models of the South Korean brand, describe the process of dismantling them and explain why ignoring this step can be fatal to the durability of your equipment.
Purpose and principle of operation of fixing elements
The compressor is the heart of any refrigeration system, and its design implies the presence of moving parts, which in working order are suspended on springs or shock absorbers. During transportation on uneven roads, these moving elements can make chaotic movements with a large amplitude, which will inevitably lead to broken tubes or destruction of internal mechanisms.
To prevent such situations, the manufacturer rigidly fixes compressor unit uses special bolts that rest against rubber bushings or directly against the motor housing. These elements transform the moving system into a monolithic structure that can withstand shaking and shock during loading.
It is important to understand that after installing the refrigerator at a permanent place of operation, these bolts become unnecessary and even harmful. They transmit vibration from the running motor directly to the refrigerator body, causing a strong hum and rattling.
⚠️ Attention: Operating the refrigerator with installed transport bolts significantly reduces the life of the compressor and can lead to its premature failure due to overload.
Some models may have not only the main ones bolts, but also additional brackets or strips that also need to be removed. Ignoring these parts will make the refrigerator inefficient and noisy.
Where to look for bolts: location on different LG models
Finding fasteners is the first step to proper installation. In most cases, manufacturers place them at the bottom of the rear wall of the unit, but the configuration may vary depending on the series and year of manufacture.
On classic models with a traditional cooling system No Frost or a drip system, the bolts are usually located symmetrically on the sides of the compressor. Their heads are clearly visible if you look behind the refrigerator, and they are often brightly colored (red or yellow) to attract attention.
In more modern models, especially in refrigerators with a linear inverter compressor, the mounting design may be changed. Here the bolts can be located not only at the back, but also at the bottom of the front panel, hidden by a decorative base.
To accurately determine the mounting location in your particular case, it is recommended to check the instructions, since the location may vary.
- 🔍 Rear wall: 4 bolts located in the corners of an imaginary rectangle around the compressor.
- 🔍 Bottom plinth: 2 bolts, access to which opens after removing the decorative panel at the bottom front.
- 🔍 Side panels: in rare cases of older models, fasteners may be located on the side walls in the lower part.
If you cannot visually detect the bolts, try carefully removing the bottom plastic panel (base) at the front of the refrigerator. Often this is where additional fixation points are hidden, which users forget about.
Step-by-step instructions for dismantling fasteners
The process of removing transport elements does not require complex equipment, but requires care and compliance with safety precautions. Before starting work, be sure to disconnect the refrigerator from the electrical outlet by removing the plug from the socket.
For work, you will need a wrench (usually 10, 12 or 14 mm in size, depending on the model) and possibly a flat-head screwdriver. In some kits, the key comes in the package with the refrigerator, but it is better to prepare your tool in advance.
☑️ Preparation for dismantling
Start by unscrewing the bolts from the back wall. Act smoothly, without sudden jerks, so as not to break the thread. If the bolt is tight, you can slightly wiggle the wrench from side to side.
⚠️ Attention: Do not use excessive force when unscrewing, so as not to damage the threads in the compressor housing, as this may lead to refrigerant leakage.
After all the bolts have been unscrewed, they must be stored. Manufacturers recommend storing them throughout the life of the refrigerator in case of repeated transportation or contacting a service center.
If the bolts have rubber bushings, they also need to be carefully removed from the holes. Sometimes they can be tight and require light force or the help of pliers to remove them (use caution).
Sealing holes after removing bolts
After removing the fasteners, through holes remain on the back (or front) wall of the refrigerator. They cannot be left open, as through them moisture and dust can penetrate into the thermal insulation layer, which over time will lead to corrosion and reduced energy efficiency.
Special plastic plugs are supplied with each new refrigerator LG . They are shaped to perfectly fit the holes and ensure a sealed housing. Usually they are in a bag with documents or attached to the inner wall of the refrigerator compartment.
Installing the plugs is very simple: just insert them into the holes until they click or fit tightly. If the plugs are lost, you can use pieces of rubber or special sealed plugs of a suitable diameter.
What to do if the plugs are lost?
If the original plastic plugs are lost, do not leave the holes open. You can cut circles from thick rubber, a car inner tube, or use large-diameter heat-shrink tubing. The main thing is to ensure the isolation of the internal space from the external environment. You can also order original plugs at the LG service center, naming the model of the refrigerator.
It is important to make sure that the plugs fit tightly and do not protrude beyond the wall, so that the refrigerator can be moved close to the wall.
Table: Fastening characteristics for different series
Different series of refrigerators may have differences in standard sizes of fastening elements. Below is a reference table that will help you navigate the necessary tools.
| LG refrigerator series | Number of bolts | Key size | Location |
|---|---|---|---|
| LG GA-B (No Frost) | 4 pcs. | 12 mm | Rear wall |
| LG GC-B (Door-in-Door) | 4 pcs. + 2 pcs. | 10 mm / 14 mm | Rear wall + base |
| LG GR-N (Classic) | 4 pcs. | 12 mm | Back wall |
| LG F-C (Side-by-Side) | 6 pcs. | 14 mm | Back panel and bottom |
Data in the table are averaged. Always check the equipment and requirements of your specific model, as manufacturers may make changes to the design without prior notice.
⚠️ Attention: Specifications and equipment may vary depending on the year of manufacture and region of sale. Always refer to the official instructions included in the package.
Frequent installation errors and their consequences
Inexperience of users often leads to common mistakes that can be costly in the future. One of the most common is an attempt to start the refrigerator without removing the transport bolts, citing the fact that “it seems to work that way.”
It works, but with an overload. A bolted compressor cannot absorb shock and all vibration is transferred to the housing. This leads to the fact that after a few months fastening the tubes it may not be able to withstand the constant shaking, and the system will depressurize.
Another mistake is the loss of plugs or their incomplete installation. Moisture penetrating through such holes condenses inside the case, causing rusting of metal parts and damage to thermal insulation.
Also, users often they forget to remove the protective film from the internal shelves and drawers, but this is a matter of aesthetics, not technical safety, unlike bolts.
FAQ: Frequently asked questions
What happens if you forget to unscrew one bolt?
If you leave at least one shipping bolt, the compressor will not be able to operate normally depreciation mode. This will cause increased vibration, loud noise and accelerated wear of the motor bearings. In the long term, this will lead to breakdown of the compressor.
Is it possible to use a refrigerator without plugs in the holes?
In the short term - it is possible, but not recommended. In the long term, dust, insects and, most dangerously, moisture will enter the case through open holes. This can cause corrosion of internal elements and a decrease in thermal insulation properties.
Where to store the removed bolts?
The best place for storage is a bag with documents for the refrigerator. You can also put them in a box from under equipment if you store it on the balcony or in the pantry. The main thing is not to throw them away, as if transported again without these bolts, the compressor may be damaged.
Do you need to wait after removing the bolts before turning it on?
Yes, after transporting and removing the fasteners, it is recommended to let the refrigerator stand in an upright position for 2 to 4 hours (and if it was lying down during transportation - up to 24 hours). This is necessary so that the oil in the compressor flows into the crankcase and is distributed throughout the system.
Is it possible to replace lost plugs yourself?
Yes, you can use any suitable rubber or plastic plugs, the main thing is to ensure tightness. However, it is better to order original plugs from an authorized service center to be sure of the quality of the material and the accuracy of the fit.
