Modern refrigerators LG No Frost are famous for their autonomy and the absence of the need for regular manual defrosting, but there are situations when the device needs to be completely turned off. This could be a scheduled wash, a move, a long absence of the owners, or a technical malfunction. Unlike older models with a drip system, units with a system No Frost have their own operational features, ignoring which can lead to compressor breakdown or the appearance of an unpleasant odor.
Many owners mistakenly believe that it is enough to simply unplug the cord from the socket, but for equipment LG the correct algorithm is important action. Incorrect shutdown may cause failure of the electronics or damage to the refrigeration circuit. In this article, we will analyze in detail all the stages of safely shutting down refrigeration equipment, from preparing food to preserving the device for long-term storage.
Following proven methods will save the life of expensive equipment. It is important to understand that air circulation in the chambers No Frost requires special attention when defrosting, since ice can accumulate in hidden air ducts. Let's look at the sequence of actions that will protect your refrigerator.
Preparing to turn off: products and settings
The first step before turning off the refrigerator LGis to work with the contents of the chambers. Temperature conditions the inside of the device does not fall instantly, so you have a time window to sort the products. It is better to immediately transfer perishable goods, such as meat, dairy products and ready-made meals, to another cold place or eat them.
If you plan to have a short shutdown for washing, the products can be left on the shelves, having first reduced the temperature to a minimum. However, for long-term storage of equipment, all shelves must be absolutely empty. Leftover food, even in closed containers, can become a source of bacteria and a persistent unpleasant odor, which will subsequently be very difficult to remove from porous plastic surfaces.
Pay attention to the settings of the electronic display. Before physically breaking the power circuit, it is recommended to put the device into standby mode, if such a function is provided by the model, or simply make sure that special modes like Super Freeze or Eco Savingare not activated. This will help to avoid errors in the logic of the controller the next time you turn it on.
- 🍎 Inspect the products and dispose of those whose shelf life is coming to an end.
- ❄️ Pack frozen semi-finished products in thermal containers with ice if defrosting takes more than 2 hours.
- 🧼 Prepare detergents and containers for collecting water in advance so that the process goes quickly.
- 🔌 Check access to the electrical outlet and make sure the surge protector is working.
⚠️ Attention: Never leave food inside the switched off refrigerator for more than 4 hours at room temperature. This creates an ideal environment for the proliferation of pathogenic microflora, even if the door is tightly closed.
Proper preparation is half the success. Do not rush to remove the cord until the chambers are cleared. Even distribution remaining products (if they are temporarily moved to the kitchen) will help keep them fresh longer while you are busy with the equipment.

Correct sequence of power off
The most critical moment is the physical disconnection from the network. Models LG with inverter compressors are characterized by high sensitivity to voltage surges. Therefore, simply unplugging the plug from the socket under load is not always the best solution, although it is acceptable in emergency cases. The ideal algorithm involves first pressing the power button on the control panel, if it is structurally implemented as a software shutdown, and waiting for the engine to stop.
If your model does not have a "Power" button on the case, then removing the plug from the socket is the only option. The important thing to be careful here is to grip the plug body, not the wire. Sudden jerks can damage contact group or the internal wiring of the refrigerator itself. After removing the plug, it is recommended to wait a few seconds before turning it on again if you are simply checking the operation of the network.
It is important to remember the restart rule. If you turn off the refrigerator, then turn it back on no earlier than after 10–15 minutes. This time is necessary for pressure stabilization refrigerant in the system. Instantly starting the compressor against high pressure in the circuit can lead to jamming or burning of the windings.
Sequence of actions:1. Unload products.
2. Press the Off button (if available).
3. Remove the plug from the socket.
4. Wait 15 minutes before turning it on again.
The electronics of modern refrigerators LG are equipped with protective relays, but you should not rely on them alone. Mechanical disconnection the circuits should occur smoothly. If you use an extension cord or surge protector, make sure that their total power matches the power consumption of the refrigerator, especially at the time of startup.
⚠️ Attention: It is strictly forbidden to turn on the refrigerator immediately after turning it off. The compressor needs time (at least 10 minutes) for the pressure in the system to equalize. Ignoring this rule is a common cause of expensive repairs.
The process of defrosting the No Frost system
Although the No Frost system (translated as “without frost”) implies automatic removal of moisture, the formation of ice cannot be completely excluded. In the evaporator, which is hidden behind the back wall of the freezer, it can still accumulate ice coat. This occurs due to infrequent defrost cycles or a loose door. Therefore, when the refrigerator is completely turned off, it is recommended to carry out manual defrosting.
To do this, leave the doors of the refrigerator and freezer compartments open for 10–12 hours. Do not use hair dryers, fan heaters, or other sources of hot air to speed up the process. A sharp temperature change can lead to deformation of plastic elements and cracks in the evaporator, which will lead to freon leakage. Natural melting is the safest method. cracks in the evaporator, which will result in a freon leak. Natural melting is the safest method.
Under the bottom of the refrigerator, especially in the freezer area, it is better to place flat containers or place absorbent rags. Water will drain not only from visible parts, but also from the drainage system. Make sure that the drainage hole is not clogged with crumbs or debris, otherwise water may overflow the edge of the tray and onto the floor.
- 💧 Leave the refrigerator with the doors open for at least 10 hours to dry completely.
- 🚿 Do not use sharp objects to chip ice - there is a high risk of breaking through the radiator.
- 🌡️ Avoid using boiling water or a hot hair dryer to speed up defrosting.
- 🧹 After the ice melts, wipe all surfaces dry with a soft rag.
The time for complete defrosting depends on the amount of frozen ice and the temperature in indoors. In winter, the process may take longer. The main thing is to achieve a state where the inside of the chambers becomes dry and there are no drops of condensation on the walls.

Why can’t you pick the ice with a knife?
In the No Frost system, the evaporator is very close to the plastic panel. One careless movement with a sharp object can pierce a thin radiator tube. Repair in this case will require calling a technician, sealing the hole and refilling with freon, which is expensive. It is better to wait until the ice melts on its own.

Washing and treatment of internal surfaces
After the ice has melted, the stage of hygienic processing begins. The plastic used in refrigerators LGis resistant to household chemicals, but it is better not to use aggressive solvents, chlorine-containing products or abrasive powders. They can damage antibacterial coating or leave micro-scratches in which bacteria will subsequently accumulate.
The optimal solution is to use a warm solution of baking soda or a mild soap solution. Thoroughly wipe down all shelves, crisper drawers, and door seals. Pay special attention sealing rubber bands: it is in their folds that mold most often hides. For hard-to-reach places, you can use a soft toothbrush.
Don't forget to wash and dry all removable elements: glass shelves, plastic containers, bottle holders. It is better to wash them separately under running water. After chemical treatment, be sure to wipe all surfaces with a clean, damp cloth to remove any remaining detergent, and then dry.
The area around the water drainage holerequires special attention. If it is dirty, clean it with a special brush or cotton swab. This will ensure proper removal of condensate during further operation of the refrigerator in the mode. Do not use flavors with strong chemical fragrances - they can transfer the smell to the products. No Frost.

Preservation of the refrigerator during long-term inactivity
If you plan not to use the refrigerator LG for a long time (for example, you are leaving for the country in winter or waiting for the delivery of new equipment), it is necessary to properly preserve the device. The main rule: the refrigerator must be stored in a dry condition. If you close an empty refrigerator, mold and a musty smell will inevitably appear inside, which will be very difficult to remove. open doors. If you close an empty refrigerator, mold and a musty smell will inevitably appear inside, which will be very difficult to remove.
Fix the doors in the slightly open position. You can use a small spacer made of cardboard or foam to prevent the door from accidentally slamming shut. This will provide air circulation inside the cameras. It is also recommended to seal the ventilation holes on the back panel with masking tape or cover them with a clean cloth to prevent dust and insects from getting inside.
Install the refrigerator in a vertical position. It is possible to tilt or lay the equipment on its side during transportation or storage, but with restrictions. If the refrigerator has been lying down, before turning it on, it must stand vertically for as long as transportation in a horizontal position lasted, but not less than 4 hours. This is necessary for drainage compressor oil into the crankcase.
| Action | Short-term downtime (up to 1 week) | Long-term downtime (more month) |
|---|---|---|
| Products | Can be left (check timing) | Remove completely |
| Doors | Tightly closed | Fixed ajar |
| Power | Disabled | Disabled |
| Temperature | Room | Room, dry place |
The storage place should be dry and protected from direct sunlight. Ultraviolet radiation destroys plastic and rubber seals, making them brittle. Also avoid proximity to heating appliances.
First startup after a long shutdown
When it's time to use the refrigerator again LG, do not rush to load it with food. After transportation or long periods of inactivity, the device needs time to acclimatize. Plug in the empty refrigerator and let it run in idle mode for 2-3 hours. During this time, it will reach operating temperature Check the operation of the compressor: it should turn on and off according to the cycles, without making any extraneous knocks or excessive noise. Make sure that cold starts to form in the freezer and that the temperature in the main compartment decreases. Only after the thermometer readings have stabilized can you begin loading with products..
Check the operation of the compressor: it should turn on and off according to cycles, without making any unusual knocks or excessive noise. Make sure that cold starts to form in the freezer and that the temperature in the main compartment decreases. Only after the thermometer readings have stabilized can you begin loading food.
Fill the chambers gradually. You should not put a large amount of warm food at once, this will force the compressor to work overload long time. Distribute food evenly without blocking the vents to ensure that the overload system functions correctly. No Frost functioned correctly.
⚠️ Attention: Specifications and control interfaces may vary depending on the specific model and year of manufacture. Always check the official User Manual for your device, especially in the sections on safety and electrical parameters.

Frequently asked questions (FAQ)
How long does it take to defrost an LG No Frost refrigerator?
For complete defrosting and drying of the system No Frost it takes from 10 to 24 hours. The exact time depends on the amount of ice frozen and the room temperature. Take your time, the moisture should evaporate completely.
Is it possible to transport an LG refrigerator lying down?
Transportation in a lying position is not recommended by the manufacturer. If necessary, you can only lay it on certain sides (indicated in the instructions), but not on the back or door. After transportation, a vertical stand of at least 4 hours is required.
Why does the LG refrigerator hum loudly after turning on?
Inverter compressors can make various sounds when starting up. If it only buzzes for the first few minutes, this is normal (system buildup). A constant strong hum, knocking or vibration may indicate a malfunction or improper installation (shipping bolts, if any, are not unscrewed, or the legs are not aligned).
Does it need to be washed if the refrigerator worked with the No Frost system?
Yes, definitely. The system No Frost only removes moisture, but does not remove odors, crumbs and bacteria. Regular washing (every 3-6 months) is necessary for hygiene and proper operation of the fans.
What to do if the control panel does not light up after turning it on?
Check for voltage in the socket. If the outlet is working properly, the protection may have tripped or there may have been a power surge. Try unplugging the refrigerator for 15-20 minutes, then turning it on again. If the panel does not work, diagnostics is required by the service center.
