Refrigerators LG with a system No Frost are deservedly popular thanks to no need for regular manual defrosting of ice. However, even the most modern models require periodic complete shutdown for general cleaning, maintenance or repair. Owners often wonder how long this process takes so as not to spoil the products or damage the equipment. The answer depends on many factors, including the room temperature, the degree of icing on the evaporator, and the model of your unit. Many people mistakenly believe that the system eliminates ice formation completely, but in practice, ice still accumulates on the hidden evaporator behind the rear wall. If you ignore the scheduled defrosting every six months to a year, this can lead to a decrease in cooling efficiency and an increase in energy consumption. Understanding the time frame of the process will help you plan your day off wisely and avoid force majeure with food storage.

In this article we will look in detail at what determines the duration of thawing, how to speed up the process safely for equipment and which steps should not be skipped. You will learn about the specifics of compressor operation LG and the nuances of caring for a complex system of air ducts. The correct approach to maintenance will extend the life of your refrigerator and keep its performance at a high level.
⚠️ Attention: If you plan to defrost the refrigerator after a long period of inactivity in an unheated room in the winter, allow the appliance to warm up to room temperature while turned off for 4-6 hours before plugging it in.
Factors influencing on the duration of the process
The time required to completely defrost the refrigerator LGvaries widely and cannot be specified to the nearest minute for all cases. The main parameter is the ambient temperature: on a hot summer day, ice will melt much faster than in a cool room in winter. The standard time range for models No Frost is from 3 to 10 hours, but these are only average values.
The amount of ice on the evaporator directly depends on the tightness of the door seals and the frequency of their opening. If the rubber circuit seal is worn out or the door does not close tightly, moist air constantly enters the chamber, instantly freezing on the cold elements. In such cases, the amount of ice can be colossal, which automatically increases the defrosting time to the maximum.
Design features of a particular model LG also play a role. In two-compartment refrigerators with a bottom freezer, the process may be uneven. Heat exchange between the chambers is hampered by partitions, so the lower part may take longer to thaw than the upper. In addition, the presence of additional functions, such as Linear Cooling or a freshness zone, implies a more complex system of air ducts, which must also warm up.
Step-by-step instructions for defrosting the refrigerator
The process of preparing for defrosting requires a sequence of actions so as not to harm the electronics and internal coatings. First you need to disconnect the unit from the power supply by removing the plug from the socket. This is a critical step, as running the compressor during defrost is not only useless, but can also lead to failure due to attempting to force refrigerant into an unfrozen system.
Next, you should empty the chambers of food. It is better to put all perishable items in thermal bags or take them out to the balcony (if the temperature is below freezing) or to a cool place. Remove all removable elements: shelves, drawers, egg containers and bottle holders. They need to be washed separately with warm water and a mild detergent.
☑️ Preparing for defrosting
After freeing the internal space, leave the refrigerator and freezer doors completely open. This will circulate warm air and speed up the melting of the ice. Place towels under the freezer compartment and in the lower part of the refrigerator compartment or install shallow trays to collect melting water so as not to flood the floor.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice inside the compartments. You may accidentally break the freon channels or damage the plastic, which will lead to expensive repairs.
Average defrosting time for different LG models
The model range LG is extensive, and the dimensions of the device directly affect the defrosting time. Compact models up to 170 cm in height usually cope with the task faster than full-length two-door giants Door-in-Door. It is also worth considering the age of the equipment: in older models, the thermal insulation may have lost its properties, which speeds up the process, but impairs normal operation.
Below is a table with the approximate defrosting time for various types of refrigerators at room temperature around +22°C:
| Refrigerator type LG | Height (cm) | Chamber volume (l) | Average defrosting time |
|---|---|---|---|
| Single-chamber | 85-140 | 100-200 | 2-4 hours |
| Double-chamber (standard) | 170-190 | 250-350 | 4-8 hours |
| Side-by-Side | 170-180 | 500-600 | 8-12 hours |
| Multi-door (InstaView) | 180-190 | 400-500 | 6-10 hours |
It is important to understand that the indicated time periods are relevant for natural thawing. If a “fur coat” thicker than a centimeter has formed on the evaporator due to a malfunction of the sensor or the door not being closed tightly, the time may increase by one and a half times. In the system No Frost ice is often hidden behind a plastic panel, so it is difficult to visually assess its quantity.
Is it possible to speed up defrosting
Often a situation arises when it is not possible to wait 8-10 hours, and users are looking for ways to speed up the process. There are safe methods that can help reduce wait times without risking equipment. The easiest way is to use a fan. Direct a stream of room temperature air into the open compartments of the refrigerator; active air circulation will significantly increase the rate of heat transfer.
Another effective method is placing containers with warm (not hot!) water in the chambers. Pour water into pots or basins and place them on shelves or the bottom of the chambers, previously covered with towels. The steam and heat from the water will gently warm the interior space. Change the water as it cools, but make sure that it is not boiling water, so as not to damage the plastic.
Why can’t you use a hair dryer?
The use of a hair dryer is strictly not recommended by manufacturers. Sudden temperature changes can lead to cracking of the plastic and damage to the varnish coating of the evaporator. In addition, there is a risk of moisture getting inside the electrical components, which will cause a short circuit.
Some users try to use heaters by installing them in front of an open refrigerator. This method has a right to exist, but requires caution. Do not place the heater too close to plastic parts and ensure that hot air does not blow directly onto one point, causing localized overheating. Raising the temperature evenly in the room is a safer option.
Cleaning and care after defrosting
After all the ice has melted and the water has been collected, the cleaning stage begins. Internal surfaces should be wiped with a soft cloth soaked in a weak solution of soda or a special product for caring for refrigerators. This will help eliminate odors and bacteria that may have grown in the humid environment. Pay special attention to the corners and joints of the panels.
Separately, you should wash and dry all removable elements. Plastic shelves and drawers LG often have a complex shape, in the corners of which dirt can accumulate. After washing, allow them to dry completely at room temperature before replacing them. Wet shelves can cause re-formation of condensation immediately after switching on.
Don't forget to clean the drainage hole if it is provided by the design of your model. In refrigerators No Frost condensation usually evaporates automatically, but in the refrigerator compartment the water drain may become clogged with crumbs. Clean it with a cotton swab or a special brush to avoid puddles at the bottom in the future.
Starting the refrigerator after inactivity
When cleaning is completed and all parts are dry, you can start starting. Place the shelves and drawers in their places, close the doors and plug in the refrigerator. Immediately set the required temperature conditions via the control panel Control. For electronically controlled models, settings may be reset, so check to see if they suit your preferences.
Don't rush to load products right away. Let the refrigerator run idle for at least 1-2 hours until it reaches operating temperature and the compressor turns off automatically. Loading warm products into the unit will create an excess load on the system cooling and will increase the time it takes to reach the cooling mode.
After the first cycle of operation, check the operation of the system No Frost. Listen to the sounds: there should be no extraneous noise, gurgling or humming that was not there before. If everything is working properly, you can gradually fill the chambers with products, observing the rules of product proximity.
What will happen if you do not defrost the LG refrigerator for years?
Ignoring defrosting will lead to fouling of the evaporator with a thick layer of ice, which will block the air channels. The refrigerator will stop freezing, the compressor will work non-stop, trying to compensate for the lack of cold, which will lead to its overheating and combustion. Electricity consumption will also increase.
Is it necessary to defrost the refrigerator if there is no visible ice on the walls?
Yes, it is necessary. In the No Frost system, ice forms on a hidden evaporator behind the rear panel. Even if the chambers are visually clean, there may be a “fur coat” there that reduces efficiency. Preventative defrosting and washing are necessary for hygiene and durability of equipment.
Is it possible to defrost a refrigerator on the balcony in winter?
No, it is dangerous. Sudden temperature changes can damage compressor oil and seals. In addition, the electronics are not designed to operate at subzero temperatures. Defrosting should only be done in a warm room.
Why does the LG refrigerator make strange sounds after defrosting?
In the first hours after switching on, gurgling or crackling sounds are possible. This is normal: refrigerant circulates, and plastic parts expand due to temperature changes. If the sounds do not go away after a day or become loud, contact the service.
