Modern household appliances require proper maintenance, and dual-chamber models of the Korean brand are no exception. Even if the indicator on the front panel is on No Frost, moisture may accumulate inside or an ice plug may form, preventing normal air circulation. Many owners mistakenly believe that such units never need defrosting, but maintenance is still necessary.
A situation where it is required manual defrosting of an LG refrigeratorcan arise for various reasons: from scheduled cleaning to a malfunction of the defrosting system. It is important to understand that ignoring the problem can lead to compressor failure or the formation of an unpleasant odor. The correct approach to the defrosting process will extend the life of your equipment.
In this article we will analyze in detail the algorithm of actions for models with different cooling systems. You'll learn how to safely unplug the device, what to do with food, and how to speed up the process without damaging the internal plastic parts. Following the manufacturer's recommendations will help you avoid costly repairs.
Determining the cooling system of your refrigerator
Before taking active steps, you need to determine exactly what cooling system is installed in your model. LG two-chamber refrigerators can be equipped with a system where no ice is formed at all, or a combined system where No Frost is used in the freezer and a drip system (Direct Cool) is used in the refrigerator compartment. The frequency and method of defrosting depends on this. Full No Frost, where no ice is formed at all, or a combined system, where No Frost is used in the freezer and a drip system (Direct Cool) is used in the refrigerator compartment. The frequency and method of defrosting depends on this.
If on the back wall of the refrigerator compartment you see a hidden evaporator and periodically appearing drops of water flowing into the groove, then you have a drip system. In this case defrosting an LG refrigerator it is required regularly, approximately once every six months. In Full No Frost models, ice should not appear at all, and if this happens, then there is a failure in the system.
⚠️ Attention: Trying to break off the ice with a knife or sharp objects in the No Frost system is guaranteed to damage the evaporator and leak freon. Repairs in this case will be very expensive.
You can also determine the type of system by the markings on the nameplate located inside the camera, or in the user manual. Series models LG GA or LG GC are most often equipped with advanced cooling systems that require minimal intervention. However, even they sometimes require a full defrosting cycle to eliminate technical problems.
Preparation for the defrosting process
The process should begin by preparing the workplace and freeing up the internal space. First of all, you need to completely disconnect the refrigerator from the power supply. Simply turning the temperature dial to zero is not enough - you need to remove the plug from the socket to completely turn off the power to the unit and start the natural defrosting process.
Next, you should empty the chambers of food. If you plan to defrost for a long time, it is better to transfer the food to another cold place or use thermal containers with ice. Frozen foods, when completely thawed, may lose their taste if the temperature rises above critical.
☑️ Preparing the refrigerator for defrosting
After removing the products, you need to remove all removable elements: shelves, drawers, egg trays and containers. It is better to wash them separately with warm water and a mild detergent. Plastic parts cannot be washed with hot water, as they can crack due to temperature changes. Interior space Must remain empty to ensure better heat transfer.
It is important to prepare the area around the refrigerator. Since melting ice produces a large amount of water, it is necessary to place absorbent rags under the doors and to the back of the unit or install low containers. Water can leak not only from the drainage hole, but also through loosely closed doors.
Natural defrosting: safe method
The safest method recommended by the manufacturer is natural defrosting. It takes longer, but guarantees no mechanical damage. After you have turned off the appliance and removed all the contents, simply leave the refrigerator and freezer doors open.
The defrosting process can take from 3 to 10 hours depending on the amount of ice and the room temperature. Do not try to speed up the process by placing bowls of boiling water inside - a sharp temperature change is dangerous for plastic and seals. LG refrigerator It should be heated gradually to avoid deformation of the internal bulkheads.
During the melting process, monitor the water level in the placed containers. If water stops dripping from the drainage hole, then most of the ice has melted. Pay special attention to the evaporator area in the freezer if you have a model with partial No Frost. The bulk of the ice often accumulates there.
While the appliance is defrosting, you can inspect the rubber seals. If they are dirty, they can be wiped with a soft cloth dampened in a mild soap solution. Clean seals provide a tight seal, which is critical for energy efficiency after switching on.
Accelerated defrosting and combating ice jam
Sometimes a situation requires an urgent solution, and waiting 10 hours is not an option. In such cases, accelerated methods can be used, but they require extreme caution. One way is to install containers with warm (not hot!) water inside the chambers. The steam generated in this case will accelerate the melting of the ice.
If an ice plug has formed in the freezer that blocks the outflow of water, you can try to gently warm the drainage hole. To do this, use a medical bulb with warm water or a soft rubber heating pad. You cannot pour water directly from the kettle - you can damage plastic parts or cause a short circuit if water gets on the electrical contacts.
| Method | Time | Safety | Efficiency |
|---|---|---|---|
| Natural | 6-10 hours | High | Medium |
| Warm water in a container | 2-4 hours | Medium | High |
| Fan | 3-5 hours | High | Medium |
| Hairdryer (with caution) | 30-60 min | Low | Very high |
Using a hair dryer is permissible only in extreme cases and only at the minimum temperature, keeping the device at a distance of at least 30 cm from the plastic. A directed flow of hot air can melt the thin walls of the chamber or deform the seals. Defrosting an LG refrigerator using a hairdryer should be carried out under constant supervision.
Cleaning the drainage system
A frequent cause of incorrect operation and ice formation is clogging drainage hole. It is located at the bottom of the rear wall of the refrigerator compartment. Through it, the condensate flows into a special tray above the compressor, where it evaporates. If the hole is clogged with crumbs or mold, the water remains inside and freezes.
For cleaning, you can use a special soft brush (often included) or a long piece of soft wire/fishing line. Do not use sharp objects that could pierce the tube. Carefully insert the tool into the hole and make several rotational movements to break through the blockage.
⚠️ Attention: After cleaning, be sure to pour some warm water into the drainage hole to make sure that it drains freely. If the water stands still, the procedure must be repeated.
It is also worth checking the condensation tray located above the compressor at the back of the refrigerator. If it is overfilled or moved, water may spill onto the floor. You can get to it by moving the refrigerator away from the wall. Make sure that the tray is installed correctly and has no cracks.
Completing the process and first start
After all the ice has melted and the water has been removed, you must thoroughly wipe the internal surfaces with a dry soft cloth. Do not leave it wet as this can quickly cause new plaque or odor to form. Allow the cameras to dry completely for 15-20 minutes.
Put all removable shelves and drawers back in place. Make sure they are securely fastened. Now you can plug in the refrigerator. It is recommended not to load it with food during the first hours so that it reaches operating temperature while idle. This will reduce the load on the compressor.
How long does it take the refrigerator to reach the temperature?
Usually, an LG two-chamber refrigerator takes 2 to 4 hours to reach the set temperature when empty. In the freezer, the process can take up to 6-8 hours. It is better to load products after the indicators go out or stop flashing.
Pay attention to the operation of the compressor after turning on. It may work continuously for the first few hours - this is normal. If you hear unusual sounds or notice that your refrigerator is not cooling, there may be air left in the system or an electronic failure. In this case, diagnostics will be required.
Frequent errors during defrosting
Many users make typical mistakes that can lead to equipment breakdown. One of the most common is the use of sharp objects to chip ice. This is strictly prohibited, since the evaporator wall is very thin, and a puncture will lead to an instant loss of freon.
Another mistake is turning on the refrigerator immediately after defrosting, without allowing it to stand. If you washed the cameras with water, moisture may have entered the electrical circuits. It is necessary to let the equipment stand turned off for at least 30-40 minutes after washing before plugging it in.
Do not ignore sensor signals. If after defrosting the alarm indicator continues to light or the display blinks, the problem may not be with the amount of ice, but with a malfunction of the defrost sensor or heating element. In models LG Smart Diagnosis you can try running self-diagnosis via a smartphone.
Why does the LG refrigerator quickly become overgrown with ice again after defrosting?
If ice appears again after a short time, check the tightness of the door. The seal may be worn out or the door may be warped. Also, the reason may be a malfunction of the defrost sensor, which does not give the command to turn on the heater to remove ice from the evaporator.
Is it possible to defrost an LG refrigerator without unplugging it from the network?
No, it is not possible. Defrosting involves turning off the compressor completely. If you leave the refrigerator on, it will try to compensate for the heat coming from the open chamber, and the compressor will burn out from overload. In addition, temperature sensors can block the operation of the system.
How often do you need to defrost an LG two-chamber refrigerator?
Models with the No Frost system do not require regular manual defrosting; it is enough to do it once a year for hygiene. Models with a drip system in the refrigerator compartment need to be defrosted every 4-6 months, or as ice forms more than 5 mm thick.
What to do if the water does not leave the drainage?
It is necessary to clean the drainage hole with warm water using a blower or soft tube. If mechanical cleaning does not help, it is possible that an ice plug has formed in the drainage tube, which will have to be defrosted with a hairdryer with great care.
Does defrosting affect the warranty?
Independent defrosting according to the manufacturer's instructions does not affect the warranty. However, if in the process you damage internal elements (pierce the evaporator, break a shelf), this case will not be covered under warranty. Always act carefully.
