Question about how Properly turning off the LG refrigerator is often a problem for owners when moving, going on a long trip, or needing to defrost. Modern models of the Korean brand, such as the DoorCooling+ or InstaViewlines, are equipped with complex electronic control systems that require correct completion of work. Simply unplugging the plug from the socket may seem like an obvious solution, but in the long run it can damage the compressor or lead to the appearance of an unpleasant odor inside the chamber.
First, it is important to understand that proper shutdown is not just a break in the electrical circuit, but a whole process of preparing the unit. Refrigerator electronics the current operating cycles must be completed, and the internal systems must go into standby mode. If you plan to turn off the equipment for a long period of time, ignoring the preparation rules will lead to the formation of mold and damage to the seals. In this article we will analyze in detail all the stages, from defrosting to preserving the device.
The need to turn off can be caused by various reasons: from routine cleaning of the condenser to transportation to a new place of residence. In each case, the algorithm of actions has its own nuances, especially when it comes to models with the system NoFrost. Although they do not require frequent manual defrosting, they still need to be cleared of ice in the hidden cavities of the evaporator before long periods of inactivity. Let's look at how to do this safely for your device.
Preparing for shutdown: emptying food
The first and most important step is to completely empty the refrigerator and freezer compartments. Do not leave food inside if you plan to turn off the power for more than 4-6 hours. Temperature conditions will begin to rise immediately after the compressor stops, which will lead to the growth of bacteria and spoilage of the contents. All perishable foods should be consumed, processed, or transferred to another working refrigerator.
After removing food, the internal shelves and drawers must be thoroughly washed. Use warm water with mild detergent or baking soda. Pay special attention to the corners of the chambers and sealing rubber bands, where crumbs or spilled liquids could remain. Plastic elements LG often have an antibacterial coating, so do not use aggressive chemicals or abrasive sponges that can damage the protective layer.
⚠️ Attention: Never use solvents, gasoline or chlorine-containing products to clean the interior surfaces of the LG refrigerator. This can lead to destruction of the plastic and the appearance of cracks on the internal walls.
After wet cleaning, be sure to wipe all surfaces dry with a clean rag. The remaining moisture will become an ideal environment for the development of microorganisms during equipment downtime. It is better to keep the doors open at this stage to ensure ventilation.
The process of defrosting and removing moisture
Even if you are the owner of a modern LG refrigerator with the system NoFrost, complete defrosting before a long shutdown is a mandatory requirement. Unlike a drip system, where water flows into a special tray above the compressor, in NoFrost systems the evaporator is hidden behind the rear panel. Moisture can accumulate there, which, when frozen, can damage plastic parts or cause corrosion.
For proper defrosting, follow these steps:
- ❄️ Turn off the power to the refrigerator by unplugging the plug from the socket.
- ❄️ Open the chamber doors and leave them in this position for at least 24 hours.
- ❄️ Cover the floor around the appliance with rags or towels in case the ice melts.
- ❄️ Remove all removable shelves, drawers and containers for separate washing.
Many users try to speed up the process by using a hair dryer or heating devices. Strictly prohibited direct hot air to the evaporator or the inner walls of the chamber. Sudden temperature changes can cause plastic to warp or damage refrigerant lines, leading to costly repairs. Natural melting of ice is the safest method.
How long does it take to defrost NoFrost?
It may take 12 to 24 hours for the ice in the hidden cavities of the NoFrost system to completely melt. Do not close the doors until you are sure that the inside is completely dry.
After all the ice has melted, you must thoroughly wipe all accessible areas with a dry cloth. Pay special attention to the drainage hole if it is visible. Moisture should not remain anywhere, otherwise, when turned on or during idle time, a musty smell will appear, which will then be difficult to get rid of.
Disconnecting electronics and removing the plug
Modern LG refrigerators are controlled by complex electronic modules. Before physically disconnecting the power circuit, it is recommended to ensure that the device is not performing any background tasks such as diagnostics or error logging. While in most cases simply unplugging the plug is sufficient, some models may react to a sudden light outage by resetting settings or displaying an error message the next time you turn it on.
If your refrigerator has the feature installed Smart Diagnosis or is connected to Wi-Fi, make sure the device is not in update or data transfer mode. After this, you can safely remove the plug from the socket. Power cord It should be carefully rolled up and secured so that it does not interfere with transportation or cleaning behind the device.
It is important to remember the safety of the electrical network. The outlet into which the refrigerator was plugged in must be working. If you turn off equipment during repairs in the apartment, make sure that the circuit breaker on the panel is also turned to the "off" position, if this is necessary according to the work plan.
Do not leave the plug hanging or lying on the floor where it could be stepped on or damaged. If the shutdown is planned for a very long period, it is better to put the cord in a compartment or carefully wrap it to the back wall, without bending it at the base.
Drying and odor prevention
The most common problem after a long period of inactivity of the refrigerator is the appearance of an unpleasant smell of mold. This is due to the fact that moisture remained inside the enclosed space, and the lack of air circulation created ideal conditions for fungi. To avoid this, after defrosting and drying, you need to carry out preventive treatment.
Use a weak solution of vinegar or special products for caring for refrigerators. Wipe not only the shelves, but also the external surfaces, including door handles and the control panel. Stainless steel (if your LG has one) requires the use of special polishes to avoid streaks and fingerprints.
The key point is to provide ventilation. If you turn off the refrigerator for storage:
- 🚪 Leave the doors of the refrigerator and freezer compartments slightly open.
- 🚪 Fix them in such a position so that they do not slam shut accidentally.
- 🚪 Use improvised means (for example, a rolled up towel) if the mechanism the door does not have an open position lock.
⚠️ Attention: During transportation or storage, the doors must be secured in the slightly open state. A closed chamber without air circulation is guaranteed to lead to the appearance of mold in 2-3 weeks.
You can also put inside an open container with activated carbon, silica gel or a special odor absorber tablet. This will help absorb residual moisture and odors from the plastic.
Features of transporting a switched-off refrigerator
If the purpose of turning it off is moving, then it is critical to follow the transportation rules. The compressor of the LG refrigerator is mounted on shock-absorbing springs, which, when shaking, can allow it to dangle and damage the tubes. Transport bolts is an element that is often forgotten to be tightened before transportation. They fix the compressor in a stationary state.
Find holes on the back wall or bottom of the refrigerator where the shipping bolts are screwed in (usually there are 2 or 4 of them). If the factory bolts are lost, bolts from the store that match the threads can be used, but this requires caution. Without fixing the compressor during transportation, the risk of failure of the unit is extremely high.
During transportation, it is also important to observe the position of the refrigerator:
| Position | Permissible angle | Risks |
|---|---|---|
| Vertical | 0 degrees | Minimum, most safe |
| Inclined | Up to 40 degrees | Possible oil leakage into the circuit |
| Recumbent | 90 degrees | High risk of damage to the compressor |
If you did transport the refrigerator lying down, under no circumstances turn it on immediately. The oil from the compressor takes time to drain back into the crankcase. This usually takes from 4 to 12 hours, depending on how long and in what position it was.
Commissioning after a long period of inactivity
After the refrigerator has been turned off and stood for some time, starting it correctly is no less important than turning it off. First, wipe the interior surfaces again to remove any accumulated dust. Make sure door seals are clean and flexible. If the rubber bands become stiff, they can be lightly lubricated with silicone grease or glycerin.
Connect the refrigerator to the power supply. The compressor may not start immediately after switching on - this is normal. The electronics perform self-diagnosis. Do not open the doors during the first 2-3 hours of operation, so that the camera quickly dials the desired temperature. Loading with products should be done gradually, in small portions, so as not to create a sudden thermal load on the system.
Check the operation of all functions:
- ✅ Assess the noise level when the compressor is operating.
- ✅ Check that whether the indicators on the control panel are blinking.
- ✅ Make sure there are no water leaks under the appliance.
- ✅ Listen to the operation of the fans (if the model is with NoFrost).
If you notice any deviations from normal operation, for example, the refrigerator is humming louder than usual or is not freezing, contact your service center Early diagnosis can save the equipment from serious damage.
☑️ Check after switching on
Remember that proper operation and timely maintenance significantly extend the life of your LG refrigerator. Following these simple rules will help you avoid common mistakes and keep your equipment in working condition for many years.
Frequently asked questions (FAQ)
Is it possible to turn off the LG refrigerator at night to save energy?
Doing this is strictly not recommended. The compressor is designed to maintain the temperature, rather than lower it back from room temperature. Daily cycles of complete defrosting and freezing will lead to rapid wear of the engine and increased energy consumption to cool the warm walls. In addition, food will deteriorate due to temperature fluctuations.
What to do if, after turning it off, an odor appears that does not go away?
If simple washing does not help, try using professional ozonizers or special odor neutralizer sprays for refrigerators. You can also place a bowl of ground coffee or activated carbon inside for a few days. In extreme cases, you will need to disassemble and clean the air ducts of the ventilation system, which is best left to a specialist.
Do door hinges need to be lubricated before long-term storage?
Yes, this is a good practice. The hinge mechanism may rust or sour from residual moisture. Use lithium grease or silicone spray, applying a small amount to the hinge axles. This will ensure easy movement of the doors after a long period of inactivity.
How to properly wash the control panel of an LG refrigerator?
The control panel Touch Control or the buttons should not be wetted directly. Lightly dampen a soft cloth with water or glass cleaner and gently wipe the surface, avoiding getting moisture into the joints of the buttons and display. After this, wipe dry with microfiber.
How long should you wait before turning it on after transportation?
If the refrigerator was transported vertically, 2-4 hours are enough to stabilize the refrigerant. If it was lying on its side or tilted strongly, the minimum waiting time before turning it on is 12 hours, and it is better to wait a full day.
