Modern brand refrigerators LG equipped with advanced freshness preservation systems, the key element of which is the filtration system. Many owners experience the appearance of foreign odors or decreased cooling efficiency, not suspecting that the reason lies in a dirty filter. Proper maintenance of this unit directly affects the hygiene of the products and the service life of the compressor.
The procedure for cleaning or replacing the filter does not require calling a technician and can be done independently in a few minutes. However, it is important to understand that different models use different types of filter elements: from simple carbon cartridges to complex c deodorizersystems. Ignoring regular maintenance can lead to the growth of bacteria and the appearance of a persistent unpleasant odor inside the chamber.
In this article we will analyze in detail the algorithm of actions for various modifications of the equipment, explain the difference between washable and disposable elements, and also answer frequently asked questions from users. Following simple rules of care will allow your equipment LG to work like new for many years.
Types of filter systems in LG refrigerators
Before taking any action, you must accurately identify the type of filter installed in your device. Engineers LG use two main air purification concepts: active carbon filtration and system Hygiene Fresh+. The first option is more often found in classic No Frost models, where the carbon element absorbs odor molecules.
The second type, Hygiene Fresh+, is a multi-stage system, including a pre-filter, a deodorizer, an antibacterial layer and a fine filter. This design allows you to capture up to 99.9% of bacteria and viruses. It is important to note that some components in complex systems are replaceable, and some are conditionally permanent, requiring only periodic cleaning.
You can determine the type of your system by the markings inside the refrigerator compartment or in the user manual. Typically, carbon filters take the form of small cassettes or mesh cylinders, while the blocks Hygiene Fresh+ are located on the back wall and have a characteristic replacement indicator.
⚠️ Attention: Do not try to wash disposable carbon cartridges with water. Water destroys the structure of activated carbon, after which the filter stops working and can become a source of mold. If the element is not marked "Washable", it must be replaced.
How often are filters changed?
The service life of a carbon filter is from 6 to 12 months, depending on the intensity of use. The indicator on the control panel (if equipped) turns red when the resource is exhausted. Hygiene Fresh+ systems require replacing the deodorizer once a year, and the pre-filter can be washed.
Necessary tools and preparation for cleaning
You do not need complex professional tools to carry out the maintenance procedure. It is enough to prepare a basic set of household supplies that can be found in every household. The main condition is the cleanliness and dryness of all items used.
You will need soft rags or microfiber, warm water and, possibly, a mild detergent without aggressive chemicals. If you plan to replace a disposable cartridge, make sure that the new element has a compatible part number for your model LG.
Before starting any work required unplug the refrigerator from the power supply. Although replacing the filter takes a little time, following safety precautions when working with electrical appliances is a must. It is also recommended to empty the shelves next to the filter for easy access.
☑️ Preparation for servicing
Step-by-step instructions: cleaning the air filter
If your model has a washable air filter (usually a mesh element in the system Hygiene Fresh+), the process of restoring it is quite simple. First, locate the location of the block, which is most often located in the upper part of the refrigerator compartment on the back wall.
Gently pull the handle or press the latch to remove the filter housing. In some models LG it is necessary to turn the cover counterclockwise. Remove the mesh element from the plastic case.
Rinse the mesh under warm running water. You can use a soft brush to remove stuck dust particles. It is strictly forbidden to use hot water or abrasive sponges, as this will damage the special antibacterial coating.
After rinsing, thoroughly shake off the water and leave the filter to dry at room temperature for at least 2-3 hours. Installing a wet element is unacceptable, as this will increase the humidity in the chamber and possible damage to the electronics.
Replacing the carbon deodorizer and cartridges
Carbon filters, unlike air meshes, have a limited resource (absorption). When the charcoal pores fill up, it stops neutralizing odors. In models LG with the system Deodorizer replacement is done by removing the old unit and installing a new one.
Find the filter compartment, which can be located on the ceiling of the chamber or in a niche on the back wall. Press the latches or pull the tab to remove the cassette. Dispose of the used element in accordance with the rules for disposal of household waste.
Remove the new filter from the packaging immediately before installation. Insert it into the grooves until you hear a characteristic click. After replacement, you must reset the filter replacement indicator on the control panel, if such a function is provided in your model.
| Element type | Cleaning method | Service life | Signs of wear |
|---|---|---|---|
| Pre-filter | Washing with water | Indefinitely | Dust, gray coating |
| Carbon deodorizer | Replacement | 6-12 months | The appearance of odors |
| Antibacterial layer | Does not require maintenance | 2-3 years | Reduced freshness of products |
| Fine filter cleaning | Replacement | 1 year | The indicator came on |
Setting and resetting the filter indicator
Modern refrigerators LG equipped with an intelligent filter condition monitoring system. After physically replacing or cleaning the element, you must inform the electronic control unit about this in order to reset the countdown timer.
On the control panel, find the button labeled Filter Reset or Eco Filter. On touchscreen models, you may need to hold the button for 3-5 seconds. In some interfaces, you need to enter the menu Settings and select the filter reset item.
If the indicator continues to light after replacement, check the fit of the filter cover. The sensor may not be able to see the closed compartment if the lid is not closed completely. The problem can also occur during power surges in the network.
⚠️ Attention: Do not ignore the flashing filter indicator. This is not just a reminder, but a signal that the load on the system fan No Frost is increasing due to a dirty air duct, which leads to increased energy consumption.
Typical errors when servicing a refrigerator
Owners often make mistakes trying to save money or speed up the process. One of the most common is an attempt to dry a wet filter directly inside a running refrigerator. This leads to the formation of an ice crust on the evaporator and malfunctions of the defrost system.
Another mistake is the use of chemical solvents or alcohol to clean plastic filter housings. Aggressive chemistry can cause microcracks in plastic LG or leave a toxic odor that will be difficult to remove. Use only water or mild soap solutions.
Also, you should not install a filter from another model, even if it is visually similar. Differences in aerodynamic resistance can disrupt air circulation, which will lead to uneven cooling of products in different zones of the chamber.
Frequently asked questions (FAQ)
Is it possible to operate a refrigerator without a filter installed?
Technically, the refrigerator will work and cool the food. However, the absence of a filter will lead to the rapid spread of odors between products and the accumulation of dust on the evaporator, which will eventually reduce the cooling efficiency.
Where to buy an original filter for LG?
Original consumables can be purchased at authorized service centers LG, specialized household appliance stores or official online brand resources. Avoid buying cheap analogues without markings.
Why is there still a smell after replacing the filter?
A new carbon filter may have a specific smell in the first hours of operation - this is normal. If the smell of food persists, the source of the smell may be on the shelves or seals, which also require washing.
How can you tell if the filter is really dirty?
Visually, the carbon filter may not change color. The main symptom is the appearance of a persistent mixed odor in the chamber, which does not disappear after ventilation. This will also be indicated by a lit indicator on the control panel.
