Modern refrigerators of the South Korean brand LG are famous for their reliability and advanced food preservation technologies, however, even the most advanced models require regular maintenance. Many owners mistakenly believe that systems No Frost or Total No Frost completely eliminate the need to defrost the unit, but this is not entirely true. The accumulation of condensation, food packed in ice and a decrease in heat transfer efficiency are real problems that every user faces after a certain period of operation.
The process of complete defrosting is necessary not only for hygienic cleaning, but also to restore normal operation compressor and fans. If you notice that the refrigerator has started to work louder, a noticeable layer of frost has appeared on the walls, or the door no longer fits tightly due to ice, then it’s time to give the appliance a “vacation”. In this article, we will analyze in detail the algorithm of actions that will help you safely carry out the procedure and avoid breakdowns of expensive components.
Following the correct sequence of steps will allow you to save time and not damage internal components, such as temperature sensors or plastic elements of the case. It is important to understand that sudden changes in temperature or the use of aggressive chemicals can cause irreparable harm, so follow the manufacturer's recommendations described below.
Preparation for the defrosting procedure
Before starting any manipulations with refrigeration equipment, it is necessary to perform a number of preparatory actions that will ensure safety and safety of your products. The first step is to turn off the power supply device by unplugging the cord from the socket, since working with electrical appliances in conditions of high humidity is unacceptable.
Next you need to empty the internal space of the camera of all products. If it is winter outside and the temperature is below zero, the contents can be taken out to the balcony, otherwise use thermal bags or put the products in bowls with ice so that they do not spoil during the procedure. It is also recommended to remove all removable shelves, drawers and containers, which are easier to wash separately under running water.
☑️ Preparing the refrigerator for defrosting
Be sure to prepare the area around the refrigerator: cover the floor with rags or towels, as flowing water can damage the flooring, especially if Is it laminate or parquet? Some models LG have a special gutter for draining melt water, but you shouldn’t rely on it alone - it’s better to be safe.
⚠️ Attention: Never leave defrosted foods at room temperature for a long time, especially meat and dairy products, to avoid the growth of bacteria.Natural defrosting: the safest method
The most gentle way to remove ice crust is natural defrosting, which takes longer, but guarantees the safety of all internal components of the cooling system. Once you have unplugged the appliance and emptied the chamber, simply leave the doors open. The ice melting process will take from 4 to 10 hours, depending on the thickness of the ice and the temperature in the room.
In models with a system No Frost there is usually little ice, and it melts faster, while in older models with manual defrosting or a drip system, the process may take longer. At this time, you can start washing the removed shelves and drawers, using a mild detergent and warm water, avoiding abrasive sponges.
Periodically check the water level in the tray or on the floor and change rags on time. If the ice is melting too slowly, you can speed up the process by placing a bowl of hot (but not boiling) water inside the chamber. The steam will help soften the ice crust, and it will begin to come off faster, without requiring mechanical action.
Why can’t you rush the process?
Artificial acceleration of defrosting using a hairdryer or hot water can lead to uneven expansion of the plastic and the appearance of microcracks in the evaporator, which will cause freon leakage in the future.
The main advantage of this method is that there is no risk of damaging evaporator or breaking the tightness of the tubes. (patience) in this case is a key success factor in extending the life of your refrigerator LG.
Accelerated methods and precautions
In situations where defrosting the chamber is urgently needed, users often look for ways to speed up the melting of ice. One acceptable method is to use hot water containers that are placed on the bottom shelf of the chamber with the door closed. The heat circulating inside the enclosed space helps to quickly soften the ice build-up.
However, it is strictly forbidden to use sharp objects such as knives, screwdrivers or ice picks to chip ice. Aluminum evaporator tubes in refrigerators LG are located very close to the inner wall, and their damage will lead to an immediate release of refrigerant and expensive repairs, which are often not economically feasible.
It is also not recommended to pour boiling water directly onto the ice crust, since a sharp temperature change can cause deformation of the plastic or cracks in the glass structural elements. If you decide to use a hairdryer, keep it at least 30 cm from the surface and constantly move it so as not to overheat one area.
⚠️ Attention: Mechanical removal of ice with a knife is the most common cause of fatal breakdowns of refrigerators, turning simple cleaning into complex repairs with replacement of the compressor.Remember that even with accelerated defrosting, it is necessary to control the process so that water does not overflow over the edge of the tray and does not get on the electrical components located at the bottom of the unit.
Features of defrosting LG refrigerators with No Frost
Model owners LG s system No Frost they often wonder if they need defrosting at all. The answer is clear: yes, it is needed, although less often than in older models. The No Frost system prevents the formation of visible ice on products and chamber walls, but moisture still condenses on a hidden evaporator located behind the rear panel.
Special
Heating element(ten) automatically thaws this ice at specified intervals and the water evaporates. However, over time, dirt, debris, and mold can accumulate in the drainage system, causing a clog. As a result, the water stops flowing, freezes and forms an ice plug that blocks the operation of the fan.To defrost such models, it is often necessary to remove the rear plastic panel inside the freezer to gain access to the evaporator and drainage hole. This requires caution, since plastic latches can be fragile, especially if the plastic is “stiffened” from the cold.
In this case, complete defrosting during the day allows you to clean the drainage naturally without using cables or flushing bulbs. After defrosting, it is recommended to blow the drainage hole with air or rinse it with warm water with the addition of soda for disinfection.

After all the ice has melted and the water has been removed, the stage of thorough cleaning of the internal surfaces begins. To wash the plastic of the camera, it is best to use a solution of baking soda (1 tablespoon per liter of water) or special products for washing refrigerators that do not contain chlorine and aggressive acids.
Pay special attention to rubber seal on the door. Dirt and black mold often accumulate in its folds, which are difficult to notice immediately. Wipe the seal with a soft rag soaked in a solution of vinegar or hydrogen peroxide to remove microorganisms and restore the elasticity of the rubber.

Wet surfaces may become covered with frost again immediately after turning on the refrigerator, so let them dry completely at room temperature.
Completion of the process and first launch
The final stage is proper assembly and first launch. Make sure all internal components are completely dry and reinstall shelves and drawers according to the instructions. Check that the door closes tightly and without gaps.
Plug in the refrigerator, but do not load food yet. Let the unit run idle for 2-4 hours so that it reaches the required temperature and reaches operating mode. At this time, you can hear the characteristic sounds of gurgling or clicking - this is normal, as the refrigerant begins to circulate through the system.
If after defrosting you find that the refrigerator is not freezing or is not working continuously, don't panic. It may take more time to stabilize the pressure in the system, or the temperature sensor has shifted during the defrosting process.
⚠️ Attention: If within 5-6 hours of operation the temperature in the chamber does not drop, and a uniform layer of frost does not appear on the back wall (in models without No Frost) or the cold is not felt, contact a service center - the circuit may be damaged or a freon leak has occurred.Regularly carrying out this procedure, according to the schedule in the instructions for your model LGwill ensure long and trouble-free operation of the equipment, maintaining food freshness and your confidence in the safety of household appliances.
How often do you need to defrost an LG refrigerator with the No system Frost?
Although the No Frost system minimizes the formation of ice, manufacturers recommend completely defrosting and cleaning the refrigerator once a year. This is necessary for disinfection, cleaning the drainage system and removing dust from the heat exchanger, which improves energy efficiency.
Is it possible to defrost the freezer with a hairdryer?
The use of a hairdryer is permissible with great care. Turn on only the cold air or minimum temperature mode, holding the hairdryer at a distance of at least 30 cm. Hot air can melt plastic or damage rubber seals and sensors.
What to do if the refrigerator does not turn on after defrosting?
Check the presence of voltage in the outlet and the integrity of the power cord. If everything is fine electrically, the compressor protection may have tripped due to moisture getting on the contacts. Leave the device turned off for a few more hours in a dry room. If the problem is not solved, you need to call a technician.
Do you need to wash the inside of the refrigerator after defrosting?
Yes, definitely. Defrosting is the ideal time to remove bacteria, mold and odors. Use safe products, such as a soda solution or special sprays, and thoroughly wipe all surfaces, including seals and hard-to-reach corners.
