Modern refrigerators of the brand LG are famous for their reliability and advanced technologies, such as a system No Frostthat minimizes the formation of ice. However, even the most advanced equipment requires periodic maintenance, and the question of how to properly start the defrosting process remains relevant for many owners. Unlike old models, where you had to wait for natural melting or pick at the ice with a knife, modern units require a more delicate approach to the cleaning procedure.
The need for defrosting can arise for various reasons: from routine maintenance and elimination of unpleasant odors to emergency situations when sensors no longer correctly read the temperature. It is important to understand that incorrect actions can lead to damage to the internal coating of the cameras or failure of the control electronics. In this material, we will analyze in detail the algorithms of actions for various types of refrigerators LG, we will explain whether there is a special mode, and how to safely prepare the equipment for cleaning.
Before taking active steps, it is worth noting that most modern models LG do not have one physical “Defrost” button on the body. The process is a set of actions, including turning off the power, preparing the cameras and, in some cases, activating service functions through the control panel. Ignoring safety rules when working with electrical appliances and refrigerant is unacceptable, so follow the instructions carefully.
Is it necessary to defrost an LG refrigerator with No Frost
Equipment owners often wonder whether it is really necessary to interfere with the operation of the system No Frostwhich is positioned as not requiring defrosting. The answer lies in understanding the principle of operation: the technology prevents the formation of visible ice on the walls by evaporating moisture, but does not eliminate the need for hygienic treatment and maintenance of hidden components. A complete absence of moisture is impossible even in a vacuum, so a minimal layer of frost can still accumulate in the hidden channels of air ducts. Manufacturers recommend completely defrosting and washing refrigeration equipment at least once a year. This is necessary not so much for removing ice, but for disinfection, eliminating bacteria and checking the operation of the drainage system. If you neglect this rule, an ice plug may form in hidden cavities, which will disrupt air circulation and lead to overheating of the compressor.

If you neglect this rule, an ice plug may form in hidden cavities, which will disrupt air circulation and lead to overheating of the compressor.
In addition, regular defrosting helps maintain the energy efficiency of the device. When the evaporator becomes coated with a microscopic layer of ice, heat transfer deteriorates and the motor has to work harder. Although the system automatic defrosting works constantly, it does not replace manual cleaning of waste products of microorganisms and stagnant odors that are absorbed into plastic parts.
⚠️ Attention: Do not try to speed up the defrosting process with a hairdryer or hot water by directing the jets directly on plastic elements. A sharp temperature change can cause deformation of the inner box or damage the evaporator tubes, which will lead to freon leakage.
Preparing the refrigerator for defrosting
Before initiating the defrosting process, it is necessary to properly prepare the unit to avoid food spoilage and damage to the kitchen interior. The first step is always to empty the cameras of their contents. All perishable foods should be removed and placed in a cool place or thermal containers with ice, as the temperature inside will begin to rise immediately after unplugging.
Next, you should disconnect the refrigerator from the power supply. To do this, remove the plug from the socket, making sure that access to it is not blocked. If the model LG is connected directly to the water supply (for example, for an ice maker), you must also turn off the water supply valve to avoid leaks when defrosting the liquid supply system.
It is important to prepare the work area around the refrigerator. Cover the floor with rags or towels, as running water can damage the floor covering. It is also recommended to remove all removable shelves, drawers and containers. It is better to wash them separately under running water, using mild detergents that do not contain abrasives.
☑️ Preparing for defrosting
Step-by-step instructions for manual defrosting
After The refrigerator LG is disconnected from the network and emptied of food, the main stage begins. Leave both chamber doors completely open. This will provide an influx of warm air and accelerate the natural melting of ice. Depending on the amount of ice and the temperature in the room, the process can take from 4 to 12 hours.
To collect melting water, you can use special trays, which are sometimes included, or simply place absorbent towels at the bottom of the chambers, which will have to be wrung out periodically. If the ice begins to chip, gently pick up large pieces, but do not force them if they are holding tightly. Mechanical impact with sharp objects is strictly prohibited.
After the ice and water have completely disappeared, you must thoroughly wipe all surfaces with a soft cloth soaked in a weak solution of soda or a special product for caring for refrigerators. Pay special attention to door seals - this is where dirt and mold most often accumulate. After wet cleaning, leave the doors open for another 30-60 minutes for complete drying and ventilation.
How to speed up defrosting safely?
To speed up the process, you can place containers with warm (not hot!) water inside the chambers. It is also permissible to use a fan directed at open doors to increase air circulation. Do not use heating devices such as heaters in close proximity to plastic.
Service mode and features of models with a display
Many users are looking for a way to enable defrosting through the menu, believing that the electronics LG has a special algorithm. Indeed, in some models with a display and function Smart Diagnosis or Wi-Fi you can run test modes, but they are intended for diagnostics and not for normal operation. The standard procedure for the user is to turn off the power mechanically.
However, there is a nuance associated with resetting defrost sensor errors. If the refrigerator stops freezing because the system “thinks” that the evaporator is clogged with ice (sensor error), sometimes it is necessary to force the defrost cycle through the service menu. Entering it is usually accomplished by a combination of buttons on the control panel, for example, simultaneously pressing Ice Plus and Freezer for a few seconds, but the exact combination depends on the specific series. LG.
If your refrigerator is equipped with a function Express Freeze or similar, make sure they are turned off before starting defrosting. These modes cause the compressor to run continuously, which may prevent self-test cycles from completing correctly after switching on. In most cases, for household defrosting, software intervention is not required.
Comparison of defrosting methods for different systems
The approach to servicing refrigerators LG may vary depending on the installed cooling system. Understanding these differences will help you avoid mistakes and maintain your equipment warranty. Below is a table comparing the main defrosting characteristics for different types of devices.
| System type | Defrosting frequency | Availability of special. mode | Risks if violated |
|---|---|---|---|
| No Frost (Full) | once a year (hygiene) | No (shutdown only) | The appearance of odor, bacteria |
| Low Frost | 1-2 times a year | No | Ice crust growth |
| Drip (Cold chamber) | 2-4 times a year | No | Water leakage out |
| Static (Old models) | As fouling | No | Damage evaporator |
Models with the system Low Frost occupy an intermediate position: they require defrosting less often than old static refrigerators, but more often than full No Frost. In such devices, it is important to monitor the condition of the door seal, since the entry of warm, moist air accelerates the formation of ice on the back wall.
For static models, which are still found in budget lines LG, it is critical to prevent the formation of a layer of ice thicker than 5-7 mm. Unlike advanced systems, there are no fans blowing the evaporator, so ice builds up evenly on the back panel, gradually reducing the useful volume of the chamber.
Typical errors and precautions
In an effort to quickly complete an unpleasant procedure, users often make mistakes that can cost expensive repairs. The most common of these is the use of knives, screwdrivers or other sharp objects to chip ice. The inner walls of refrigerators LG often have hidden channels with refrigerant, and damage to them leads to instant depressurization of the system.
Another mistake is turning on the refrigerator immediately after the last piece of ice has melted. The electronics and compressor need time for the refrigerant to settle in the right parts of the circuit and for the contacts to dry. It is recommended to wait at least 2-3 hours after complete drying before connecting to the network.
⚠️ Attention: Never turn on the refrigerator if there is still water inside or condensation on the electrical contacts of lamps and sensors. This can cause a short circuit and failure of the control board.
It is also worth mentioning the use of aggressive chemistry. The plastic used in LGis resistant to food acids, but may become cloudy or crack when exposed to solvents, acetone or strong alkalis. For disinfection, a solution of baking soda or citric acid is sufficient.
Frequently asked questions (FAQ)
Is it possible to defrost an LG refrigerator without unplugging it?
Absolutely not. Defrosting requires a complete stop of the compressor and fans. If you leave the device on, it will try to compensate for the heat coming from the open chamber, which will lead to overload and damage to the motor. In addition, water can get on electrical components.
How long should you keep the refrigerator turned off?
The minimum time for the ice to completely thaw and moisture to evaporate is 12 hours (a full day is preferable). This ensures that there are no hidden ice plugs in the internal channels and on the evaporator, which could disrupt the operation of the system. No Frost.
What should you do if the refrigerator does not freeze after defrosting?
If, after turning it on and passing 2-3 hours of operation, the temperature does not decrease, check whether the doors are tightly closed and whether the fast freezing mode is turned on incorrectly. If the problem persists for more than 6-8 hours, there may be a power surge or damage to the sensor during defrosting, and a service call is required.
Do the seals need to be lubricated after defrosting?
Yes, this is an excellent practice. After washing and drying, it is recommended to wipe the rubber door seals with silicone grease or glycerin. This will maintain their elasticity, prevent cracking and ensure a tight fit of the door, which is critical for energy efficiency. LG It is recommended to wipe with silicone grease or glycerin. This will maintain their elasticity, prevent cracking and ensure a tight door seal, which is critical for energy efficiency.
Is defrosting dangerous for the electronics of the refrigerator?
If you follow safety rules, no. The main thing is that water does not pour into the technical holes and onto the control board. If you used a hairdryer to dry the camera, make sure all parts are cool and dry. Static electricity can also be dangerous, so before touching the internal electronic components (if you touch them), it is better to touch a grounded metal object.
