Modern refrigerators LG are famous for their reliability and advanced technologies for preserving food freshness. However, even the most advanced models, including No Frost or Total No Frostsystems, may eventually require owner intervention. Many users mistakenly believe that such units never need to be defrosted, but this is not entirely true.
The accumulation of ice crust, the appearance of an unpleasant odor, or scheduled general cleaning are the main reasons why you will have to deal with the issue of defrosting. Incorrect actions during this period can cause serious damage to the compressor or damage the internal coating of the chambers.
In this article we will analyze in detail the algorithm of actions for safe defrosting, explain the difference between servicing different models and answer the most frequently asked questions. Compliance with these rules will extend the life of your equipment and ensure hygienic storage of food.
Is it necessary to defrost an LG refrigerator with No Frost
Owners of equipment marked No Frost are often surprised to learn that defrosting is necessary. Indeed, in such models, moisture does not settle on the walls in the form of frost, but evaporates through a special system. However, complete tightness the chamber requires periodic sanitary measures.
Once a year and a half, it is recommended to completely defrost it to clean it from bacteria and dust that accumulates in hard-to-reach places. In addition, if you have not used the unit for a long time or a piece of meat has defrosted in the chamber, it is simply necessary to rinse the system.
⚠️ Attention: Even if there is no ice on the walls, ignoring preventive measures can lead to clogging of the drainage hole and the appearance of puddles under the vegetable drawers.
For models without an automatic system defrosting procedure is mandatory every 6–8 months. In such cases, the ice coat inevitably grows, reducing operating efficiency thermostat and increasing energy consumption.
Preparation for the defrosting procedure
Before starting active operations, it is necessary to properly prepare the workspace and the equipment itself. First of all, empty the freezer and refrigerator compartments of all food. Take care in advance about where food will be stored during the process, especially if it’s a hot summer outside.
Remove all removable elements: shelves, drawers, containers and racks. It is better to wash them immediately in warm water with a mild detergent and leave them to dry at room temperature. Plastic LG is sensitive to temperature changes, so do not wash cold shelves with hot water.
☑️ Preparing the refrigerator for defrosting
It is also important to prepare the area around the unit. Cover the floor with rags or place towels, as when the ice melts, water may leak outside the chamber. If your model has a special gutter for draining water, make sure that it is not clogged.
Step-by-step instructions: how to turn off and defrost
The most important step is the correct shutdown. Never try to speed up the process by using a hair dryer, knife or other sharp objects. Mechanical chipping of ice can damage evaporatorcausing refrigerant leaks and costly repairs.
Simply unplug the power cord from the outlet and leave the doors open. To speed up natural melting, you can place a container with warm (not boiling water!) water inside the chamber. The process takes from 4 to 24 hours, depending on the amount of ice and the temperature in the room.
⚠️ Attention: Using a hairdryer is only permissible in cold air mode and from a long distance. The hot jet can deform the plastic door seal or melt internal parts.
While the ice is melting, wipe the internal surfaces with a soft cloth. Do not use abrasive sponges or harsh chemicals, which can soak into the plastic and then transfer to the food.
What to do if the water does not drain?
If you notice that water is standing at the bottom of the chamber, check the drainage hole. It often becomes clogged with crumbs or ice. Carefully clean it with a cotton swab or a special brush, which is often included.
How long does defrosting take?
The duration of the process directly depends on the thickness of the ice layer and the ambient temperature. In the summer, when the apartment is warm, the ice can disappear in 3–5 hours. In winter, with heating running, this period can increase to 10–12 hours.
Models LG with a large freezer volume and dense insulation retain the cold longer, so do not rush to close the doors. Make sure the inside is completely dry and there is no moisture left in the corners or seals.
Once completely dry, wipe all surfaces dry with a clean cloth. This will prevent the formation of a new ice crust immediately after switching on and eliminate the risk of mold.
Comparison of models: No Frost vs. Drip System
Understanding the type of refrigerator you have helps to correctly assess the frequency of procedures. The table below shows the key differences in the maintenance of different types of units LG.
| Characteristics | No Frost / Total No Frost | Drip system (Direct Cool) |
|---|---|---|
| Defrost frequency | 1 time every 1-2 years (for hygiene) | 2 once a year (required) |
| Presence of ice | Absent during proper operation | Formed on the back wall |
| Procedure time | 3-5 hours | 8-12 hours |
| Risk of damage | Low (if you don’t pick) | Medium (thin evaporator tubes) |
Owners of models with a drip system need to be especially attentive to the rear wall This is where open evaporatoris located, which can easily be pierced with a knife when trying to chip off the ice.
Starting the refrigerator after defrosting
After you have washed everything and wiped it dry, you can start starting it. Plug in the appliance, but do not load any food yet. Let the compressor idle to reach the required temperature.
Usually this process takes from 2 to 4 hours. The fact that the mode has been achieved will be indicated by a lit indicator on the control panel or a characteristic clicking of the relay. Only after this can you carefully place the food.
Do not overload the chambers with a large amount of warm food at once. This will force compressor to work hard, trying to cover a large amount of heat. Load products gradually.
Frequent defrosting errors
Many users make typical mistakes that shorten the life of the equipment. One of the most common is the use of chemical solvents such as ice or boiling water. A sharp temperature change is dangerous for plastic parts and tubes.
Another mistake is turning on the device ahead of time. If there is moisture left inside, it will quickly turn into ice and performance will decrease. Also, do not leave the refrigerator turned off for months without supervision.
⚠️ Attention: If you plan not to use the appliance for a long time, leave the doors ajar. This will prevent the appearance of a musty smell and the proliferation of fungus inside the enclosed space.
Following simple operating rules will allow your refrigerator LG to serve faithfully for many years. Regular maintenance takes less time than complex repairs.
Is it possible to defrost an LG refrigerator with a hairdryer?
Using a hairdryer is possible, but with serious limitations. Turn on only cold air and keep the device at a distance of at least 30 cm from the inner walls. Hot air can deform the plastic and damage the seals.
What to do if the refrigerator does not freeze after defrosting?
Let the unit run empty for 5-6 hours. If the temperature does not decrease, check that the doors close tightly. If the problem persists, perhaps the circuit was damaged during defrosting or the relay failed, you need to call a technician.
How often should you wash a refrigerator with the No Frost system?
It is recommended to carry out a complete hygienic defrosting and washing at least once a year. This will help eliminate bacteria that could get there along with the food and prevent the appearance of unpleasant odors.
