Modern two-chamber refrigerators brand LG, equipped with an advanced system Total No Frostare positioned as devices that do not require regular manual defrosting. However, even the most advanced air circulation mechanisms and evaporators require periodic maintenance, which cannot be carried out without completely disconnecting the unit from the power supply. Owners often wonder whether it is necessary to defrost equipment if ice does not form clearly, or should they wait for problems with cooling to appear.
The need for the procedure can be caused not only by routine maintenance, but also by emergency situations, such as a breakdown of the defrost sensor or a clogged drainage channel. Ignoring these signals will result in reduced energy efficiency and overload of the compressor. In this material, we will analyze in detail how to safely carry out defrosting so as not to damage the fragile elements of the system No Frost.
It is important to understand that the process of freeing the chamber from ice and moisture is not just waiting for thawing, but a set of measures to hygienic processing and checking the technical condition. The right approach will extend the life of your LG and maintain food freshness at the proper level in the long term.
When it is necessary to defrost an LG refrigerator
Although the system No Frost automatically removes moisture from cameras, there are scenarios where user intervention becomes mandatory. The first sign that defrosting is needed is often the appearance of frost in the bottom corners of the freezer or on the back wall of the refrigerator compartment, indicating poor air circulation. Another reason for shutting down is the appearance of an unpleasant odor that cannot be eliminated by simply washing the shelves.
If you notice that the refrigerator has become louder than usual or the compressor cycles have become more frequent, this may indicate that the heat exchanger is covered with a layer of ice. In such cases forced defrosting helps restore normal operation of the evaporator. Sometimes the problem lies in a loosely closed door or damage to the seal, which requires careful diagnosis.
⚠️ Attention: If ice builds up too quickly (literally in a couple of days), this may indicate a malfunction of the defrost heating element or thermostat. In this case, simple defrosting will only give a temporary effect, and you will need to call a specialist.
It is recommended to carry out a planned procedure at least once a year, even if there are no visible problems. This removes microscopic food particles and bacteria that may have entered the ventilation system. Regular maintenance will ensure that your two-chamber refrigerator works at maximum efficiency.
Preparation for the defrosting procedure
Before starting any manipulations with the electrical appliance, it is necessary to ensure the safety of the process. The first step should always be to completely disconnect the device from the power supply. Unplug the plug from the socket, making sure that access to it will not be blocked during work. This is critically important, since water entering live parts can lead to a short circuit.
Next, the chambers should be freed of food. All frozen and refrigerated supplies should be removed and placed in a cool place, wrapped in blankets or thermal bags to minimize temperature loss. If there is a lot of food, it is advisable to turn off the refrigerator at night or while you are at home to control the process.
☑️ Preparing the LG refrigerator for defrosting
Remove all removable elements: glass shelves, plastic containers, egg trays and bottle holders. It is better to wash them separately in warm water and a mild detergent. The internal space is also freed from any foreign objects. Only after this can you begin to prepare the area around the unit.
Step-by-step instructions for defrosting
The process of natural melting of ice is the most gentle for the internal components of the refrigerator LG. Open the doors of both chambers and leave them in this position. To speed up the process, you can place towels soaked in hot water at the bottom of the chambers, changing them as they cool. However, the use of hair dryers or heating devices is strictly not recommended.
Water formed during melting will flow into a special groove on the back wall. In working models, it goes through the drainage hole into a container above the compressor, where it evaporates. If you see water overflowing the pan or leaking onto the floor, the drain is clogged or frozen. In this case, carefully remove excess moisture with a rag or syringe.
The duration of the procedure depends on the amount of ice and the temperature in the room. Typically, it takes from 4 to 10 hours to completely defrost a two-chamber unit. Do not try to speed up the process by mechanically chipping the ice, as this may damage the evaporator, which is located behind the plastic panel.
What to do if the drainage is clogged?
If water is in the chamber and does not drain, carefully clean the drainage hole with a soft wire or brush. You can pour a little warm water and soda into it to dissolve the fatty deposits blocking the drainage.
Cleaning and care during defrosting
While the chambers are free of ice and food, it is the ideal time for general cleaning. Use a weak solution of baking soda or a special refrigerator cleaner. Avoid harsh chemicals and abrasive sponges that can scratch plastic or enamel. Thoroughly wipe all surfaces, including corners and panel joints.
Pay special attention to the rubber seals on the doors. Dirt and mold often accumulate in the folds, which breaks the seal. Wipe them with a soft cloth soaked in soapy water and check for cracks. If the rubber band comes off, it can be heated with a hairdryer (with caution) or replaced.
After wet cleaning, be sure to wipe all surfaces dry. No moisture should remain inside before switching on. Also check the ventilation holes on the back of the chambers to ensure they are not blocked by food or debris. The cleanliness of the ventilation system is the key to proper operation air circulation.
⚠️ Attention: Never use solvents, gasoline or chlorine-containing products to clean the internal chambers. They can damage the plastic and leave a toxic odor, which is subsequently absorbed into the food.
Typical mistakes when defrosting
Many users, wanting to save time, make mistakes that can cost expensive repairs. The most common of them is using a knife or other sharp objects to chip ice. In systems No Frost the evaporator is very close to the plastic casing, and it is extremely easy to break through it. Repairing such damage is difficult and requires sealing and charging with freon.
Another mistake is using a hair dryer or heater to speed up the melting. Sudden temperature changes can lead to deformation of plastic parts, cracks on shelves or damage to pipes. In addition, hot air can melt the insulation of the wiring if the jet is directed in the wrong direction.
Some try to wash the refrigerator without unplugging it, or turn it on immediately after washing, without waiting for it to dry. This is a gross violation of safety regulations. Water inside the case can cause electronics to short-circuit or contact corrosion.
| Action | Correct | Incorrect |
|---|---|---|
| Ice removal | Natural melting | Chipping with a knife |
| Cleaning shelves | Warm water + soft sponge | Boiling water or abrasives |
| Drying | Natural or dry fabric | Hairdryer or heater |
| Turning on | After complete drying | Immediately after washing |
Starting the refrigerator after defrosting
After all defrosting and cleaning procedures have been completed, it is necessary to allow the unit to dry completely. Leave the doors open for another 15-20 minutes to allow any residual moisture to evaporate. Make sure that all removable elements are installed in their places correctly and securely.
Now you can connect the refrigerator to the network. Please note that you should not immediately load food inside. Let the device run idle for 1-2 hours so that it reaches the required temperature and stabilizes the operating mode. Only then return the products to the shelves.
During the first hours of operation, listen to the sounds made by the compressor. If you hear gurgling or hissing sounds, this is normal as the refrigerant is beginning to circulate through the system. However, an extraneous knocking or humming noise may indicate that something was dislodged or damaged during the defrosting process.
