Owners of modern equipment often face with the opinion that units with the system No Frost never require defrosting. This is a common misconception that can lead to damage to expensive equipment. Despite the advanced moisture removal system, any refrigerator LG, like other brands, needs periodic maintenance for stable operation.
Complete shutdown of the device is necessary to clean the internal channels, eliminate unpleasant odors and check the tightness of the seals. If you ignore this procedure, an ice plug may form in hidden cavities, blocking air circulation. In this material we will analyze in detail how to defrost correctly and safely so as not to damage the equipment.
It should be understood that even with automatic defrosting of the evaporator, fine ice and frost can accumulate in hard-to-reach places. Regular maintenance will extend the life of the compressor and maintain energy efficiency. Next, we will look at the algorithm of actions that is suitable for most models of the South Korean manufacturer.
Why ice forms in the No Frost system
Many users are surprised to find ice in a unit that supposedly should not freeze. The system No Frost works on the principle of forced air circulation, which passes through the evaporator, is cooled and supplied to the chambers. Moisture from the food settles on the cold evaporator, where it automatically thaws at specified intervals.
However, this process is not ideal. If you frequently open the door or leave it open, a large amount of moist air enters the chamber. The system does not have time to remove all the moisture, and it crystallizes. Also, the cause may be a violation of tightness rubber seals or clogging of the drainage hole.
⚠️ Attention: If ice forms only in one corner or in a specific place, this often indicates a local malfunction, and not the need for planned defrosting. In this case, it is worth checking the integrity of the gaskets.
Ice accumulation can also occur inside the technical channel where the evaporator is hidden. Visually you may not see it, but the operation of the fan fan will be difficult. This leads to noise, humming and poor freezing quality. It is to clean such hidden areas that it is necessary to completely disconnect the device from the power supply.
- ❄️ Frequent opening of doors in a hot room leads to a sharp influx of humid air.
- 🥩 Hot food placed in the chamber sharply increases humidity and load on the system.
- 🚪 A loose door or damaged magnetic seal will compromise the seal of the circuit.
It is important to note that some models LG have an intelligent control function, but it does not replace physical cleaning. Mechanical removal of ice with a knife or sharp objects is strictly prohibited, as this leads to depressurization of the cooling system and leakage of freon.
Preparation for the defrosting procedure
Before starting any work, it is necessary to properly prepare the workplace and the unit itself. You should not start the process in a hurry, as it takes time. The first step is always to remove all products. They need to be transferred to another cold place or use thermal bags with ice to maintain freshness.
After releasing the chambers, you should unplug the device. To do this, you need to unplug the plug from the socket. Important not just press the power button on the control panel, but physically break the electrical circuit. This will ensure safety and stop the compressor from working.
Next, you need to remove all removable elements: shelves, drawers, egg trays and bottle holders. Glass can crack due to a sharp temperature change, so it is better to wash glass shelves separately with warm water rather than leaving them inside while defrosting. It is also better to remove plastic containers for ease of access to the walls.
☑️ Preparing for defrosting
Prepare a place to collect water. Since melt water will flow down, cover the floor around the refrigerator with thick rags or towels. Some models LG are provided with a special tray for collecting condensate, but during active defrosting its volume may not be enough.
Step-by-step instructions for defrosting
The safest and most correct way to defrost a refrigerator LG is natural thawing. This method takes longer, but guarantees the safety of all plastic elements and the integrity of the cooling system. Do not try to speed up the process with external heat sources.
After you have turned off the appliance and removed the food, leave the doors of all chambers completely open. Circulating air at room temperature will start the ice melting process. Depending on the amount of ice, this may take from 4 to 24 hours.
During the thawing process, it is necessary to periodically check the condition and remove melting water. If water accumulates at the bottom of the chamber, carefully scoop it out with a mug or wipe it with a cloth. Make sure that water does not get on the electrical controls or inside the housing.
Can you use a hair dryer?
Use of a hair dryer is permissible only in extreme cases and with great care. The air flow should be warm, but not hot, and directed strictly at the ice formations, avoiding plastic walls. Prolonged exposure to hot air can deform the plastic and damage the seals. We recommend using this method only for removing ice blockages in the drain, and not for general defrosting.
Pay special attention to the drain hole, which is usually located on the back wall of the refrigerator compartment. If it is clogged, water will sit at the bottom. You can clean it with a special soft brush or a cotton swab. After cleaning, it is recommended to pour a small amount of warm water into it to check the passage of the channel.
- 🚿 Wipe the inner walls with a soft sponge soaked in a weak solution of soda.
- 🌡️ Do not use hot water to speed up the melting, so as not to damage the plastic.
- 🧹 Make sure that the drainage the hole is free of debris and ice.
When all the ice has melted, thoroughly wipe all surfaces dry. The humidity inside the chambers must be kept to a minimum before restarting. This will prevent the instant formation of a new layer of frost when starting the compressor.
What you absolutely cannot do
There are a number of actions that can irreversibly damage the equipment. Often the desire to save time leads to expensive repairs. Never do not use sharp objects (knives, screwdrivers, chisels) to chip ice. By breaking through the evaporator wall, you will release the refrigerant, and restoring the system will not be economically feasible.
It is also prohibited to use open fire sources or powerful heating devices in close proximity to plastic. Plastic elements of the camera and internal parts of the system No Frost melt at relatively low temperatures. Deformation of the plastic will lead to loss of tightness and loss of presentation.
⚠️ Attention: A sharp temperature change caused by pouring boiling water can lead to cracks in glass shelves and deformation of plastic drawers. Use only warm water.
Do not turn on the refrigerator as soon as the last piece of ice has melted. Allow the system to dry and warm up to room temperature. Starting the compressor with moisture on the contacts or in the control unit can cause a short circuit.
Cleaning and disinfection after defrosting
The defrosting period is the ideal time for general cleaning. While the chambers are empty, you can remove all the dirt that has accumulated for months. For washing, use mild detergents that do not contain abrasives or chlorine. Aggressive chemicals can destroy plastic and leave a persistent odor.
An excellent natural remedy for removing odors and disinfecting is a baking soda solution. Dissolve 2 tablespoons of baking soda in 1 liter of warm water. This solution safely removes grease and neutralizes unpleasant odors from food.
After wet cleaning, be sure to wipe all surfaces with a dry, clean cloth. Pay special attention to corners and joints where water could remain. Door seals also need to be wiped and checked for cracks or dirt.
| Element | Cleaning agent | Tool | Features |
|---|---|---|---|
| Plastic walls | Soda solution or special agent | Soft sponge | Do not rub with the hard side |
| Glass shelves | Glass cleaner | Microfiber cloth | Avoid sudden temperature changes |
| Rubber seals | Warm soapy water | Cotton swab | Check for integrity |
| Drain hole | Warm water | Brush or pear | Clean carefully |
To eliminate persistent To remove odors after washing, you can use activated carbon or special odor absorbers, placing them inside the chambers for several hours before turning them on. This will ensure freshness immediately after loading the products.
Starting the refrigerator after servicing
After completing all defrosting and cleaning procedures, the stage of proper startup begins. Don't rush to load products right away. Plug in the empty refrigerator and leave it idle for at least 2-3 hours. This will allow the system to reach the required temperature and stabilize work processes.
Make sure that the unit is level. Check the feet and adjust them if necessary. Tilt of the equipment can disrupt the operation of the water drainage system and lead to the doors not closing properly. The door should close tightly and open easily when opened to 45 degrees.
When the temperature stabilizes, you can gradually load the products. Don't overcrowd the refrigerator right away; let the air circulate. Distribute food evenly without covering the ventilation holes.
- ⏱️ Let the refrigerator run empty for 2-3 hours before loading.
- 📏 Check that the equipment is installed horizontally with a level.
- 🌬️ Make sure that the ventilation grilles inside are not closed products.
Compliance with these simple rules will allow your LG to serve for a long time and reliably. Regular maintenance of the system No Frost reduces the load on the compressor and saves energy.
Frequently asked questions (FAQ)
How often should you defrost an LG No Frost refrigerator?
Manufacturers recommend a complete defrost and a general cleaning at least once a year. However, if you notice a decrease in operating efficiency, the appearance of ice or foreign odors, the procedure should be carried out earlier.
Is it possible to defrost a refrigerator without unplugging it?
No, this is prohibited by safety rules. Defrosting is only possible when the power supply is completely turned off. A running compressor in an unloaded refrigerator may overheat, and water entering the electrical components will cause a short circuit.
What to do if the refrigerator does not freeze after defrosting?
If, after turning it on and after 3-4 hours, the temperature does not drop, check whether the doors are tightly closed and whether the temperature settings have been lost. If the problem persists, it is possible that damage or failure of the electronics occurred during the defrosting process, a call to a technician is required.
Do the seals need to be lubricated after defrosting?
Yes, this will extend their service life. After drying, the rubber seals can be wiped with a special silicone grease or glycerin. This will prevent the rubber from drying out and losing elasticity.
