Modern refrigerators LG have proven themselves to be reliable and technologically advanced devices that can keep food fresh for years. However, even the most advanced equipment requires regular attention from the owner to maintain optimal performance. Proper care of the unit allows you not only to avoid sudden breakdowns, but also to significantly reduce energy consumption, which is especially important at current tariffs.
Many users mistakenly believe that simply wiping the shelves from dust is enough. In fact, refrigerator maintenance is a set of measures, including checking seals, cleaning the ventilation system and monitoring the condition of the compressor. Ignoring these procedures can lead to overheating of the engine or the appearance of an unpleasant odor, which is then difficult to remove.
In this article we will analyze in detail all the stages of caring for refrigerators LG, including models with the system No Frost and classic drip defrosting. You will learn how to safely clean internal and external elements, when it is necessary to call a specialist, and what tasks you can handle on your own in 15–20 minutes.
Primary preparation and safety precautions
Before starting any manipulations with an electrical appliance, it is necessary to ensure the safety of the process. The first and most important rule is to completely disconnect the device from the power supply. You should not rely only on the power button, if there is one on the case; It is better to unplug the plug from the socket to eliminate the risk of electric shock when working with internal components.
Free the chambers from food. If you are planning a deep cleaning, it is better to temporarily move the food to another cold place or use thermal bags with ice. To wash internal surfaces, use warm water with the addition of a mild detergent or a special spray for household appliances. Aggressive chemistrycontaining chlorine or abrasive particles can damage the plastic coating of the chambers.
⚠️ Attention: Never use sharp objects such as like knives or screwdrivers to remove ice or dirt. Damage to the evaporator will lead to a refrigerant leak and costly repairs, which are often not economically feasible.
Prepare the necessary tools in advance. You will need soft sponges, microfiber, a container of water and possibly a vacuum cleaner with a narrow attachment. If your model has a water filter, make sure that you have access to a spare cartridge in case it needs to be replaced during servicing.
Care for the external surface and door seals
The appearance of the refrigerator LG often suffers from fingerprints, especially if you have a coated model Stainless Steel or Matte. To clean such surfaces, use special polishes or a damp microfiber cloth. Movements should be directed along the texture of the metal to avoid the appearance of streaks and micro-scratches, which will become noticeable over time.
Particular attention should be paid rubber seals to the doors. They are responsible for the tightness of the chamber. Over time, dirt, grease and food debris accumulate on them, which can lead to loss of elasticity and a loose fit of the door. This, in turn, causes the compressor to work harder, increasing wear.
- 🧼 Wipe the seals with warm soapy water once a month, thoroughly washing away dirt from the folds.
- 🔍 Regularly check the integrity of the rubber: on it there should be no cracks, cuts or creases.
- 🚪 Make sure that the door closes tightly: a sheet of paper sandwiched between the door and the body should be removed with force.
If you find that the seal has lost its shape, you can try to restore it by heating it with a hairdryer at low temperature and straightening it by hand. However, in case of severe damage, the only solution will be replacement of the seal to a new original set.
Cleaning the ventilation and drainage system in No Frost
Refrigerators LG with system No Frost do not require manual defrosting, but need clean air ducts. Clogged ventilation ducts can lead to uneven cooling of the chambers and the formation of ice plugs that block air circulation. Shelves and drawers may need to be removed to access the back of the chamber.
A critical element is drainage hole. Through it, condensate formed during defrosting is removed. If the hole becomes clogged with crumbs or mold, water will begin to accumulate at the bottom of the refrigerator or under the crisper drawers. You can clean it with a soft tube or a cotton swab dipped in warm water.
Sequence of cleaning the drainage:1. Disconnect the refrigerator from the network.
2. Remove the lower drawers and shelves.
3. Find the drainage hole on the back wall.
4. Carefully clean with a brush or soft wire.
5. Pour in some warm water to check the drainage.
It is also worth checking the condition of the fan if it is possible to get to it without completely disassembling it. Dust on the blades can create noise and reduce airflow efficiency. Gently remove dust with a dry brush or vacuum cleaner at minimum power.
Maintenance of the compressor and condenser
The compressor is the “heart” of your refrigerator LG. Modern models often use inverter compressors Inverter Linear Compressor, which are characterized by quiet operation and durability. However, they are sensitive to overheating, which is often caused by contamination of the heat exchanger (condenser) located on the rear wall or at the bottom of the case.
Dust, pet hair and lint that accumulate on the radiator grille act as a heat insulator. This interferes with efficient heat dissipation, causing the unit to operate at its maximum capacity. It is recommended to clean the condenser at least once a year, and if you have pets - every 6 months.
| Element | Cleaning frequency | Tool | Risk of ignoring |
|---|---|---|---|
| Condenser (grid at the back) | once a year | Vacuum cleaner, brush | Overheating, rising light bills |
| Area around the compressor | once every 6 months | Dry rag | Corrosion, noise |
| Cooling fan | once every 2 years | Brush, compressed air | Noise, bad cold |
To clean, move the refrigerator away from the wall, providing access to the back panel. Carefully run the vacuum cleaner brush along the coils of the radiator, being careful not to bend the thin tubes. If the dust is compressed, you can use a can of compressed air, but you need to blow carefully.
Replacing filters and maintaining the water supply system
If your The refrigerator LG is equipped with a water dispenser and an ice maker; the quality of filtration directly affects the taste of drinks and the health of the family. Filters have a limited lifespan, usually 6 months or 300 liters (depending on the model and water hardness). The expiration date of the cartridge does not mean that water will stop flowing, but its cleaning will become ineffective.
Modern models are equipped with a filter replacement indicator on the control panel. When the corresponding icon lights up, you must purchase an original cartridge LG or a compatible analogue with suitable characteristics. The replacement process is simple and does not require tools: usually it is enough to turn the old filter counterclockwise and insert the new one until it clicks.
⚠️ Attention: After installing the new filter, be sure to run 5-10 liters of water through the system. This is necessary to remove coal dust and activate the filter element. The first portions of water may be dark in color - this is normal.
Do not forget to periodically wash the drip tray under the dispenser. Mucus or mold often forms there due to constant humidity. It is better to wash removable parts in warm water with a mild detergent.
What to do if the filter indicator does not reset?
In some models LG you need to hold down the "Ice Plus" button or the special "Filter Reset" button for 3-5 seconds. If this does not help, try unplugging the refrigerator for 1 minute, then turning it on and repeating the reset procedure.
Frequent problems and their prevention
Even with regular care, situations may arise that require intervention. Most often, users encounter extraneous noise, insufficient cooling, or ice formation in unexpected places. Understanding the causes of these phenomena will help you quickly fix the problem or understand when a technician is needed.
For example, if the refrigerator is humming louder than usual, check whether it is level. The legs should be adjusted so that the body does not wobble, and the door closes itself when opened slightly. Also, the source of noise can be vibration from nearby objects or dishes inside the chambers.
- ❄️ Ice in the freezer: Check the tightness of the door closure and the condition of the seal. Warm air may be entering the chamber.
- 💧 Water on the floor: Check the drainage hole and the level of inclination of the refrigerator (it should be slightly tilted back).
- 🔊 Knocks or clicks: May be caused by plastic expansion or the operation of the compressor, but if the sound is sharp, diagnostics is needed.
If you notice that the refrigerator LG has stopped freezing, but the compressor is working, do not rush to disassemble the unit. Let it sit unplugged for a few hours. Sometimes the control system is blocked due to a failure, and a reboot helps restore normal operation.
☑️ Monthly maintenance checklist
Seasonal preservation and long-term storage
If you have a long business trip or you are leaving your country house for the winter, the refrigerator must be properly preserved. Simply unplugging the device from the outlet is not enough. Moisture may remain inside, which will lead to mold and corrosion of metal parts.
After defrosting and thoroughly washing, leave the refrigerator doors LG ajar. This will allow air to circulate and prevent a musty smell. Ideally, it is better to lock the doors in the open position so that they do not accidentally slam shut and become damaged.
Critical important: When preserving in an unheated warehouse or cottage in winter, make sure that there is no water left in the system, which, if frozen, can break the evaporator tubes. For models with running water, it is necessary to turn off the water supply tap and drain the remainder from the system.Is it possible to transport the LG refrigerator lying down?
Transporting the refrigerator in a lying position is extremely undesirable. Oil from the compressor may leak into the refrigerant circuit, causing water hammer when first turned on. If transportation lying down is unavoidable, the unit should only be laid on the side opposite to the location of the compressor, and turned on no earlier than 24 hours after installation in a vertical position.
How often do you need to defrost a No Frost refrigerator?
The system No Frost assumes automatic defrosting of the evaporator. However, once a year (preferably in the fall), it is recommended to completely defrost the refrigerator manually for general cleaning, disinfection and checking hidden cavities. This will extend the life of the equipment.
Why does the LG refrigerator make clicking noises?
Single clicks may be the sound of the thermostat or compressor relay operating, which is normal. Plastic cracking occurs due to thermal expansion of materials. If the clicks are frequent, loud and accompanied by a stop in cooling, this may indicate a malfunction of the start relay or the compressor itself.
