Modern refrigerators of the brand LG with technology No Frost are deservedly considered one of the most reliable and easy to use, however, even they require regular and high-quality care to maintain ideal hygiene.
Many owners mistakenly believe that the absence of ice on the walls of the chamber completely eliminates the need to carry out defrosting, but this is not true, because dust and bacteria accumulate inside the hidden channels and on the evaporator over time.
Proper cleaning not only extends the life of the compressor and fans, but also ensures that your products will be stored in safe conditions without the risk of foreign odors or mold.
Preparation for washing and necessary tools
Before you begin active actions, it is necessary disconnect the device from the power supply, since working with water and an electrical appliance at the same time is strictly prohibited by safety rules.
You will need to prepare in advance soft sponges that do not scratch plastic and microfiber for final wiping and special detergents that do not contain aggressive abrasives or chlorine.
For washing the internal shelves and drawers, warm water with the addition of a small amount of liquid soap or a special spray for household appliances, which is easily washed off, is ideal.
⚠️ Attention: Never use hot water to wash the internal chambers, as how a sharp temperature change can lead to the appearance of microcracks on plastic parts and deformation of seals.
Make sure that you have a basin on hand for soaking removable elements and a separate towel for drying hard-to-reach places inside the case.
The process of defrosting the No Frost system
Although the system No Frost automatically removes moisture, an ice crust may form on the evaporator located behind the rear wall over time due to leaks or frequent opening of doors.
After turning off the power, leave the doors of the refrigerator and freezer completely open for at least 2-3 hours so that all hidden ice has time to melt and flow into the drainage system.
Do not try to speed up the process using a hair dryer or heating devices, as plastic air ducts they may melt and heat the defrost heating element artificially heat can damage it.
Why does water flow under the refrigerator?
If after defrosting water flows onto the floor, check the drainage hole. It often becomes clogged with crumbs or ice. Clean it with a special flexible brush or soft wire wrapped in cotton wool.
During the defrosting process, it is recommended to periodically check the tray located above the compressor at the rear of the unit and, if necessary, carefully scoop out any accumulated water.
Complete drying of the internal surfaces is a critical step that cannot be ignored before repeating turning on.
Cleaning internal chambers and removable elements
All removable shelves, glass inserts, plastic containers for vegetables and bottle holders must be removed from the body and washed separately in the bathtub or under the shower.
For glass shelves, use warm water, and for plastic - cool, to avoid deformation, carefully rinsing each element to remove any residual detergent.
Wipe the inner walls of the chamber with a soft sponge, moving from top to bottom, paying special attention to the corners and places where shelves are attached, where dirt most often accumulates.
- 🧼 Liquid laundry soap does an excellent job of removing greasy stains on the walls.
- 🍋 A solution of citric acid will help remove yellow plaque and refresh plastic.
- 🌿 Chamomile decoction or water with the addition of tea tree essential oil disinfect surfaces.
After wet cleaning, be sure to wipe all surfaces dry with a clean microfiber to prevent the formation of condensation immediately after switch on.
☑️ Checklist for cleaning the chamber
Care of seals and doors
The rubber seal around the perimeter of the doors is a guarantee of tightness, and its cleanliness directly affects the efficiency of work compressor and absence ice.
Crumbles, mold and sticky dirt often accumulate in the folds of rubber, which must be carefully removed using a cotton swab dipped in a soapy solution or a special rubber cleaner.
After cleaning, it is recommended to lubricate the seal silicone grease or glycerin to maintain its elasticity and prevent cracking of the material over time.
⚠️ Attention: If after cleaning you find cracks, creases or areas on the seal where the rubber does not fit tightly to the body, you must replace the part, otherwise the refrigerator will work with overload.
The outer surface of the doors, especially if it is a model LG DoorCooling+ or a refrigerator with a coating Anti-Fingerprint, it should be washed with special products for stainless steel or a soft damp cloth.
Movements when wiping the external panels should be directed along the texture of the metal, if any, to avoid streaks and micro-scratches.
Maintenance of the drainage system and vents
The key element of the system No Frost is the drainage hole through which defrosting moisture flows into the evaporator, and its permeability should be checked during each general cleaning.
Locate the hole on the back wall of the fridge compartment (usually it is hidden by a plastic box or visible below) and make sure that it is not clogged with food debris or ice.
To clean it, you can use a special soft brush or a piece of soft wire twisted into a bundle, carefully moving it inside the channel.
It is also worth inspecting the ventilation grilles on the back wall, through which cold air circulates, and if there is dust, carefully remove it with a dry soft brush.
Impaired air circulation leads to uneven cooling of products and increased load on the defrosting system.
Removing unpleasant odors
If, after a high-quality wash, an unpleasant odor remains inside, it means that bacteria could penetrate into hard-to-reach places or be absorbed into plastic parts.
An effective and safe way to eliminate odors is to use natural absorbents, which are placed on shelves for several days.
You can use activated carbon, ground coffee in an open container, soda in a fabric bag, or special odor absorbers for refrigerators.
In some cases, the smell may come from the drainage hose, and then a deeper flush of the system with a soda or peroxide solution is required hydrogen.
Regular checking of products and timely disposal of spoiled stocks is the best prevention of the appearance of persistent odors.
Table: Recommended cleaning agents
The choice of the right cleaning agent depends on the type of contamination and surface material, so it is important to navigate the properties of various compositions.
Below is a table that helps you choose the best option for different tasks when caring for yours LG.
| Type of contamination | Recommended product | What to avoid |
|---|---|---|
| Fatty stains | Laundry soap solution | Abrasive powders |
| Mold in the sealant | Vinegar solution or peroxide | Chlorine bleach |
| Scaling on parts | Citric acid | Hot water |
| Dust on the grilles | Dry soft brush | Damp cloth without wringing |
Use of inappropriate chemicals can lead to clouding of the plastic or destruction of the protective coating of the internal walls.
Always thoroughly rinse off any, even the safest, product with plenty of clean water.
Common mistakes when caring for a refrigerator
One of the most common mistakes is trying break off the ice with a knife or other sharp object, which almost guarantees damage to the cooling system and leakage of freon.
Also, owners often forget to wipe the back wall and top of the case, where kitchen dust and grease settle, forming a sticky coating that is difficult to remove.
Ignoring cleaning the condenser grille at the back of the refrigerator (if it is open) leads to overheating of the motor and increased energy consumption.
Is it possible to wash the inside of a refrigerator with a steam generator?
The use of a steam generator is not recommended for plastic internal chambers, since hot steam can deform thin elements and damage electronic sensors if they are located close to the surface.
Do not forget that even the most modern models No Frost require human attention and periodic general cleaning.
Following simple rules of operation and care will allow your refrigerator LG to serve flawlessly for many years.
How often should you wash the LG No Frost refrigerator?
General cleaning with defrosting is recommended to be carried out at least once every 6 months. If a lot of products with a strong odor are stored in the chamber or a leak occurs, cleaning must be done immediately.
Can window cleaners be used?
Window cleaners can only be used on the outer glass or metal surfaces of doors. They are not suitable for internal plastic and rubber seals, as they may contain alcohol or ammonia, which destroy materials.
What to do if the refrigerator does not turn on after cleaning?
Make sure that you have completely dried all contacts and internal surfaces before turning on. If the refrigerator does not start 3-4 hours after connecting to the network, perhaps moisture has entered the electrical circuit, and it needs to be dried in a warm room for 24 hours.
How to lubricate the door seal?
It is best to use a special silicone grease for rubber, glycerin or baby oil. These products maintain the elasticity of the rubber and prevent it from drying out and cracking.
