How to properly defrost an LG No Frost refrigerator: instructions

Refrigerators with a system No Frost from the company LG have earned a reputation as reliable devices that relieve owners from the need to regularly scrape off ice. However, even the most modern models require periodic maintenance. Many users mistakenly believe that the absence of ice on the walls of the chamber completely eliminates the issue of defrosting, but this is not so. Air circulation and condensate removal systems require preventive maintenance in order for the equipment to operate silently and efficiently for many years.

The need to carry out a complete defrost may arise for various reasons: from routine general cleaning to eliminating an unpleasant odor or foreign objects entering the system. Ignoring this procedure may result in the evaporator becoming covered with a “coat” of ice, which will significantly increase the load on compressor. As a result, the refrigerator will start to work louder, consume more electricity, and in some cases even stop freezing.

The process of defrosting equipment LG has its own nuances that distinguish it from servicing old drip models. It is important here not just to let the ice melt, but also to properly prepare the electronics, clean the drainage system and pause before turning it on again. Compliance with the technology will avoid costly repairs and extend the life of the household appliance.

Why does the No Frost system need defrosting?

The principle of operation No Frost (translated as “no frost”) implies constant circulation of dry air inside the chambers, so moisture does not settle on the walls in the form of ice. However, microscopic water particles are still present in the air and gradually settle on the hidden evaporator located behind the rear panel. In normal mode, this ice automatically thaws with each compressor operating cycle, and water is removed through the drainage hole.

Problems begin when the system cannot cope with moisture removal or when the user violates the operating rules. Over time, the drain tube may become clogged due to crumbs, mold, or greasy film. The water stops flowing, freezes and turns into an ice plug. It is in such cases that it is required full defrostingwhich cannot be performed automatically.

⚠️ Attention: If you notice that water has begun to accumulate under the refrigerator or ice has appeared in the lower part of the freezer, this is a sure sign that the drainage is clogged and requires immediate intervention.

In addition, defrosting is necessary for high-quality disinfection. Inside the refrigerator LG ideal conditions are created for the growth of bacteria, especially in hidden cavities where direct light does not reach. Regular washing with power off allows you to destroy pathogenic microflora and prevent the appearance of a musty smell that can permeate food.

Preparation for the defrosting process

Before taking active steps, you need to properly prepare the equipment and the surrounding space. Disconnecting the power this is the first and most important step. Simply turning off the button on the case is not enough; you need to physically unplug the cord from the outlet. This ensures that no electrical processes will interfere with defrosting, and the sensors will reset their values.

The next step is releasing the chambers. All products should be removed and transferred to another cold place or use thermal containers with ice so that they do not have time to deteriorate during the procedure. Shelves, drawers and containers also need to be removed. Plastic structural elements LG are quite durable, but at low temperatures they become brittle, so it is better to wash them separately in warm water, rather than inside the case.

Prepare a place to collect water in advance. Despite the fact that refrigerators LG have a tray for collecting condensate, its volume may not be sufficient for a large amount of melt water, especially if you are defrosting the device for the first time in a long time. Place a few old towels or rags on the floor in front of the refrigerator to protect the floor covering from moisture.

Step-by-step instructions for defrosting

The defrosting process itself requires patience. The main rule is not to try to speed up the thawing of ice by mechanical or thermal influence. Open the refrigerator and freezer doors and leave them in that position. The natural process will take from 4 to 12 hours, depending on the amount of ice and the temperature in the room.

During this time, water will flow into a special groove inside the chamber and through the drainage tube into a container under the compressor. Check the tray periodically and empty it if necessary to prevent water from overflowing onto the floor. If the drainage hole is clogged, it must be carefully cleaned.

To clean the drainage, use a soft brush or a long flexible wire with cotton wool at the end. Be careful not to damage the inner walls of the canal. After cleaning, you can pour a little warm (not hot!) water into the hole to make sure that the liquid flows freely.

⚠️ Attention: Never use a hair dryer, hot water from a kettle or sharp objects (knife, screwdriver) to chip ice. This may lead to depressurization of the cooling system or damage to plastic parts, which is not a warranty case.

What to do if the ice does not melt?

If a lot of time has passed and the ice crust remains, check whether the door of the adjacent chamber is tightly closed (if it is a double-circuit one). Also make sure the room is warm enough. In rare cases, ice may block the fan, then you will need to call a technician to remove the back panel.

Cleaning and disinfecting internal surfaces

After all the ice has melted, the washing stage begins. For the interior walls of the refrigerator LG it is best to use special household appliance products or a weak soap solution. Aggressive chemicals containing chlorine or abrasive particles can damage the plastic coating and lead to the appearance of microcracks in which bacteria will subsequently accumulate.

Wipe all surfaces thoroughly, paying special attention to corners, door seals and the drainage channel exit. This is where mold most often forms. The rubber seal needs to be bent back and the folds washed, as crumbs and dirt often remain there. After wet cleaning, be sure to wipe all surfaces dry with a clean cloth.

Removable elements deserve special attention: shelves made of tempered glass and plastic drawers. They can be washed in the sink using regular detergents. The main thing is to let them dry completely and warm up to room temperature before putting them back in the refrigerator to avoid thermal shock.

Rules for drying and starting the refrigerator

Many users make the mistake of starting the refrigerator immediately after wet cleaning. Residual moisture in hard-to-reach places, especially in the area of ​​the evaporator and ventilation ducts, can instantly turn into ice when the compressor is turned on. This will again create a problem for the system No Frost. Therefore, the drying step is critical.

Leave the refrigerator doors open for at least 1-2 hours after finishing washing. Make sure the room has good ventilation. Only after making sure that all surfaces are completely dry can you begin assembly. Return the shelves, containers and drawers to their places, close the doors tightly.

Now you can turn on the device. Please note that the compressor may not start immediately - the electronics LG conducts self-diagnosis. Let the refrigerator run idle (without food) for 2-3 hours. During this time, it will reach the required temperature, and only after that you can load the products.

Typical errors during defrosting

Ignorance of technical nuances often leads to the fact that owners inadvertently harm their technology. One of the most common mistakes is trying to speed up the process. Using a hair dryer creates a sharp temperature difference, which is detrimental to the plastic and metal tubes of the evaporator. Local overheating can cause deformation of materials.

Another mistake is ignoring the drainage hole. Users wash the visible walls, but forget to clean the water drainage channel. As a result, within a short time after switching on, ice forms in the freezer again, and the cycle of problems repeats. It is important to understand that drainage system is the “throat” of the entire moisture removal mechanism.

Also, you should not turn on the refrigerator if it has not yet dried or if a large amount of warm food has been immediately loaded into it. This forces the compressor to work at its limit for a long time, which reduces its life. Following the sequence of actions is the key to the longevity of the device.

Is it possible to defrost an LG No Frost refrigerator if there is no ice in the freezer?

Yes, it is recommended to carry out scheduled defrosting and washing at least once a year, even if there is no visible ice. This is necessary for disinfection, cleaning the drainage from mucus invisible to the eye and checking the operation of the system.

How long should the refrigerator be turned off before turning it on?

The defrosting process itself takes from 4 to 12 hours. After washing, it takes another 1-2 hours to dry. Thus, the total downtime is on average 6-14 hours. It is not recommended to turn on the appliance earlier.

What to do if after defrosting the refrigerator does not freeze?

Perhaps moisture has gotten into the electrical contacts or the drainage is clogged. Leave the device turned off for a few more hours in a warm room. If the problem is not solved after 24 hours of operation, contact the service center.

Do you need to lubricate the seals after washing?

Yes, this will extend the life of the rubber. After drying, wipe the seals with special silicone grease or glycerin. This will prevent the rubber from drying out and cracking.

Is it dangerous to wash a refrigerator with a steam generator?

The use of a steam generator is not recommended for the internal chamber of refrigerators LG. Hot steam under pressure can damage the thermal insulation layer or electronic sensors located in the walls.
