Modern refrigeration units of the brand LG are characterized by a complex design and high reliability, however, even the highest quality equipment requires maintenance or repair over time. Owners are often faced with the need to get to internal components to replace a thermostat, check a compressor, or clear a blockage in the water drainage system. Self-disassembly is a process that requires care, knowledge of the device and compliance with safety precautions so as not to damage fragile plastic elements or expensive electronics.
Before proceeding with dismantling, it is important to understand that the design may differ significantly depending on the model, be it a classic two-chamber version or an advanced system No Frost with an inverter motor. Incorrect actions can lead to leakage of the circuit or damage to the insulation, so each step must be meaningful. In this article, we will look in detail at the disassembly stages, the necessary tools and the key nuances of working with various components of refrigeration equipment from a Korean manufacturer.
The main goal of any intervention is to gain access to a specific component with minimal risk to the rest of the equipment. Disconnection from the power supply is the first and mandatory step, which cannot be ignored. Next, you should free up the internal space, remove all shelves and drawers to ensure free access to fasteners and panels.
Preparation of tools and safety measures
To successfully dismantle panels and assemblies, you will need a minimum set of tools that can be found in the arsenal of most home craftsmen. The main tool will be a Phillips screwdriver, since it is Phillips screws that are used by the manufacturer to fasten most external and internal elements. You may also need a flat-head screwdriver to carefully pry up plastic latches, which are often used in modern models LG to secure decorative overlays.
Particular attention should be paid to safety, since working with electrical appliances and refrigerant carries certain risks. Before starting any manipulations, make sure that the power cord is unplugged from the outlet. If you plan to work on the rear of the unit where the compressor is located, you must allow the equipment to cool down if it has been running recently to avoid burns from the hot condenser tubes.
⚠️ Attention: Never cut through or bend the copper tubes of the cooling system. Damage to the circuit will lead to a freon leak, after which you will need to call a specialist to vacuum and refill the system, which will significantly increase the cost of repairs.
For ease of work, prepare a container for folding the fasteners, since the screws can be of different lengths and purposes. Losing even one small screw during assembly can lead to vibration or loose panels. It is also recommended to have gloves on hand to protect your hands from the sharp edges of the metal case and possible contamination.
- 🛠️ Phillips and flathead screwdrivers of different sizes for screws and latches.
- 🧤 Work gloves to protect your hands from cuts and dirt.
- 📦 Container for sorting fasteners.
- 🔦 Flashlight for illuminating hard-to-reach places inside the case.
☑️ Preparation for disassembly
Dismantling the door and internal shelves
The first stage of disassembly is usually removing the door, especially if you need to transport the refrigerator through a narrow doorway or replacing the seal. In models LG with a system Door Cooling+ or a built-in display on the door, the procedure may have its own characteristics, but the general principle remains similar. First, you need to remove all removable elements from the door itself: balcony shelves, bottle holders and decorative strips.
The door is secured to the body using hinges, which can be located at the top and bottom. The top hinge is often covered with a decorative cover, which must be carefully removed by prying it off with a flat-head screwdriver. After unscrewing the fastening bolts, the top hinge is removed and the door can be lifted.
Nuances of hinges with closers
In some premium models, the hinges may be equipped with closing mechanisms or have a complex design. Before removing completely, check for additional locking pins or hidden screws under stickers.
Interior shelves and drawers can usually be removed without tools, but sometimes they can be secured with stoppers. The plastic guides on the sides of the camera may also require removal if the side panel needs to be removed. Be careful with the tempered glass of the shelves - it is durable, but is not susceptible to impacts on the end.
⚠️ Attention: When removing the door with the electronic control module (if the display is located on the facade), be sure to disconnect the power cable going through the top hinge before completely separating the door from the body.
Removing the rear panel and accessing the compressor
The rear wall of the refrigerator is the main access to the “heart” of the unit, the compressor, and the refrigerant circulation system. In most models LG this panel is secured with several screws around the perimeter. After unscrewing them, the metal or plastic sheet is easily removed, revealing a view of the motor-compressor, capacitor and start-up relay.
Dust often accumulates in this area, which can interfere with heat transfer, so cleaning this area is often the reason for disassembly. However, if your goal is to replace the compressor or filter drier, you must proceed with extreme caution. The tubes leaving the compressor are under pressure, and their damage is unacceptable without special equipment for pumping out freon.
| Component | Location | Function |
|---|---|---|
| Compressor | Lower part, rear | Refrigerant compression and circulation |
| Condenser | Rear grille | Gas cooling and condensation |
| Starting relay | On the compressor housing | Starting the compressor engine |
| Filter drier | At the outlet of the condenser | Removing moisture from the system |
When When replacing a start relay or thermocouple, it is important to remember the orientation of the parts, since they can only be installed in one position. Electrical contacts must be clean and fit tightly. Any traces of carbon deposits or insulation melting indicate a malfunction that requires replacement of the element.
Disassembling the interior of the No Frost chamber
In refrigerators with a system No Frost the back wall inside the refrigerator or freezer compartment hides the evaporator and fan. To access them, you need to remove the plastic panel, which is often secured not only with screws, but also with many plastic clips. The screws may be hidden under decorative plugs or plastic covers.
The process of removing the inner back wall requires patience. Plastic becomes brittle in the cold, so all actions must be performed smoothly, without jerking. If the panel does not come off, check that all screws are removed, including any that may be inside drawers or under shelves. Often, the fasteners are hidden under the brand logo or in the recesses of the handles.
After removing the panel, access to evaporator, the defrost heating element and the temperature sensor becomes available. This is where ice most often freezes if the defrost system does not work correctly. A visual inspection allows you to identify a burnt-out heating element or a faulty sensor. Also in this area there is a channel for draining melt water, which can become clogged with debris or ice.
⚠️ Attention: Do not use sharp metal objects to chip ice on the evaporator. One awkward movement can pierce the thin tubes of the aluminum radiator, which will lead to freon leakage.
Removing the control panel and electronics
Modern refrigerators LG are equipped with complex control modules that can be located on the top of the case, inside the chamber or on the door. Access to the electronic board often requires partial disassembly of the top cover or removal of the decorative casing. The module is usually secured with screws and plastic latches.
Electronic components are sensitive to static electricity and moisture. Before touching the board or disconnecting connectors, it is recommended that you discharge any static charge by touching a grounded metal object. All cables and wires should be disconnected by holding the connector body, and not the wires themselves, so as not to break the contacts.
If swollen capacitors, traces of burning or oxidation are visible on the board, this indicates the need to replace the module or repair specific elements. However, electronics diagnostics require special knowledge and equipment. In most cases, if the control board is faulty, it is completely replaced with an original or compatible one.
- 🔌 Carefully disconnect all cables, fixing their position.
- 📸 Take a photo of the wire connection before disconnecting.
- 🧼 Clean the contacts contact alcohol solution during oxidation.
- 🔍 Inspect the board for microcracks and swelling.
Resetting electronics errors
Sometimes after replacing sensors or heating elements, it is necessary to reset the error in the controller's memory. This can be done by unplugging the refrigerator for 15-20 minutes, or using a combination of buttons depending on the model.
Assembly and performance testing
After carrying out the necessary repairs or replacing parts, the assembly stage begins. This process is a mirror image of disassembly, but requires even more care. It is important to remember to replace any insulating materials that may have been removed or moved during the work. The seals should lie flat, without creases.
When tightening the screws, do not use excessive force, especially when working with plastic. Threaded connections they should be tightened tightly, but not fanatically, so as not to strip the threads or crack the plastic insert. All removed decorative plugs and trims are returned to their places last.
The final stage is to check the functionality. After turning on the refrigerator, listen to the operation of the compressor and fans. There should be no extraneous noise, knocking or vibrations. During the first hours of operation, monitor the temperature in the chambers and the absence of water leaks. If all parameters are normal, disassembly can be considered successful.
⚠️ Attention: Do not load the refrigerator with food immediately after turning it on. Give the equipment 2-3 hours of idle operation to reach operating mode and stabilize the temperature.
Frequently asked questions (FAQ)
Need Is it possible to defrost the refrigerator before disassembling?
Yes, if you plan to work with the internal chamber or evaporator, the refrigerator must be completely defrosted and dried. This will prevent water from getting on the electrical components and will make it easier to remove plastic panels, which become brittle in the cold.
Is it possible to remove the back metal wall without removing the door?
In most cases, the back panel can be removed without completely dismantling the door. However, if access to the bottom screws or hinges is difficult, removing the door will greatly facilitate the process and protect it from damage during operation.
What to do if the plastic latch breaks during disassembly?
If the latch breaks off, the panel can be fixed using a small amount of plastic glue or use a thin self-tapping screw, first drilling a hole. The main thing is to ensure a tight fit of the panel so that air circulation is not disturbed.
Is it dangerous to change the compressor yourself?
Replacing a compressor requires special tools (burner, vacuum degasser, pressure gauge station) and skills in working with refrigerants. It is not recommended to carry out this procedure without experience and equipment, as there is a high risk of damage to the system or poor-quality soldering.
