Sooner or later, every home cook is faced with the need for general cleaning inside the refrigerator. Accumulated odors, spilled food or simply routine hygiene require completely emptying the unit of its contents and thoroughly washing it. However, for brand equipment LG, especially models with the system No Frost, the process of preparing for washing has its own important technical nuances, ignoring which can lead to breakdown of expensive components.
The main task of the owner is not just to unplug the cord from the socket, but to do it safely compressor i electronic module. In this article, we will analyze in detail the algorithm of actions that will allow you to put the refrigerator in order without causing harm to its internal mechanisms and maintaining the manufacturer’s warranty.
Before taking active steps, you need to understand why haste is unacceptable here. An abrupt shutdown of a running unit can cause water hammer in the cooling system if the freon has not had time to stabilize. In addition, proper planning of the process will save you time and protect food from rapid spoilage during defrosting.
Preparing for a shutdown: safety and food
The first step is to completely unload the refrigerator compartments. You need to remove all products, shelves and removable drawers. To preserve the contents, you can use a balcony in winter, and thermal bags with ice in summer. It is important to act quickly to minimize the loss of cold before starting the main stage.
In parallel with unloading the products, cleaning tools should be prepared. You will need soft sponges, microfiber and a detergent that does not contain abrasive particles. Aggressive chemistry can damage the plastic coating of the internal walls, which will lead to the appearance of microcracks and the growth of bacteria in the future.
⚠️ Attention: Never use a knife or other sharp objects for chipping ice, even if you have a model with manual defrosting. Damage to the evaporator will lead to freon leakage and costly repairs.
Pay special attention to searching for documentation or checking the model of your device. Some older models LG are characterized by a drip system, while modern units are all equipped No Frost. Understanding the type of your device will help you correctly estimate the time required for defrosting.
The correct algorithm for turning off the power supply
Many users make the mistake of simply pulling the plug from the socket under load. Although modern models LG are reliable compressors, it is considered correct to first turn off the device through the control panel. This allows the electronics to complete current cycles and enter standby mode.
Locate the on/off button on the control panel. Depending on the model, it can be sensory or mechanical. If the indicators on the display are lit, press and hold the power button for about 3-5 seconds until the screen goes completely blank. Only after this can you begin to physically disconnect from the network.
When removing the plug from the socket, hold onto the plastic body of the plug itself, and not the wire. Sudden jerks can damage the internal contacts of the cable, which over time will lead to sparking or heating of the wiring. Make sure that the socket is in good condition and has no signs of oxidation.
After disconnecting from the network, give the equipment a couple of minutes to “rest” before starting active manipulations. This is necessary to equalize the pressure in the refrigerant system. Although modern compressor oils have good fluidity, a pause of 5-10 minutes will not be an unnecessary precaution. system LG have good fluidity, a pause of 5-10 minutes will not be an unnecessary precaution.
Features of defrosting No Frost and drip systems
Refrigerator owners LG with the system No Frost are often mistaken, believing that they do not need to be defrosted at all. Yes, an ice coat does not form on the walls, but moisture from the food settles on the hidden evaporator, which is located behind the rear panel. Periodic shutdown is necessary so that this moisture has time to evaporate through the drainage.
For models with a drip system (crying evaporator), the defrosting process takes longer. Here ice forms directly on the back wall of the working chamber. You will need to leave the doors open for at least 12-24 hours, depending on the thickness of the ice. It is strictly prohibited to speed up this process with a hair dryer or heating pads.
| System type | Defrosting time | Do I need to wash? | Frequency |
|---|---|---|---|
| No Frost | 2-4 hours | Yes, necessarily | Once every 6-12 months. |
| Drip | 12-24 hours | Yes, necessarily | Once every 6 month |
| Combined | 4-6 hours | Yes, necessarily | Once every 6-8 months. |
During defrosting, place absorbent towels under the doors and in the lower part of the chamber. Melt water may contain food debris and bacteria, so it is important not to let it spread across the kitchen floor. If your model LG has a special gutter for draining water, make sure that it is not clogged.
What will happen if you do not defrost No Frost?
Although there will be no ice blocks, the drainage hole may become clogged with mucus and mold. This will cause water to start flowing inside the chamber or under the refrigerator, and an unpleasant musty smell will appear, which is difficult to remove.
The process of washing and disinfecting the internal chambers
When the ice has completely melted, you can begin washing. Use warm soapy water. pH neutral dishwashing detergents or special sprays for household appliances are ideal. Wipe all surfaces thoroughly, paying attention to the corners and joints of the panels, where dirt most often accumulates.
Removable elements - tempered glass shelves and plastic containers - are best washed separately in the bath or under the shower. This will allow you to clean them from all sides and reach hard-to-reach places. Do not place cold glass directly under hot water - the temperature shock can cause it to break.
- 🧼 Use a soft sponge on major surfaces to avoid leaving scratches.
- 🦷 A toothbrush will help remove dirt from rubber seals and small crevices.
- 💧 Thoroughly rinse all parts with clean water to remove any remaining detergent.
The area on the doors requires special attention. This is where black mold most often settles. Wipe the folds of the rubber with a cotton swab dipped in hydrogen peroxide or vinegar solution. This will not only clean, but also disinfect the material, maintaining its elasticity. sealing rubber bands on the doors. This is where black mold most often settles. Wipe the folds of the rubber with a cotton swab dipped in hydrogen peroxide or vinegar solution. This will not only clean, but also disinfect the material, maintaining its elasticity.
Care for the external surface and ventilation system
While the internal chambers are drying, take care of the appearance of your LG. If you have a model coated with Stainless Steel (stainless steel) or Matrix Paint, use only special polishes or a damp microfiber cloth. Movements should be strictly along the texture of the metal so as not to leave chaotic marks.
An important, but often ignored step is cleaning the back panel. There are the condenser (black grill) and the compressor itself. Dust that accumulates there over the years acts as a heat insulator, causing the motor to work harder and consume more electricity.
⚠️ Attention: Before cleaning the back panel, make sure that the refrigerator is completely unplugged. Use a vacuum cleaner with a soft attachment or a dry, soft brush. Do not use water to clean electrical components!
Also check the ventilation holes inside the chamber (usually they are located on the back wall or at the top). Make sure they are not clogged with crumbs or ice. Free air circulation is the key to proper operation of the system No Frost and uniform temperature distribution.
☑️ Checklist before switching on
Drying and first start after washing
The most critical mistake is to turn on the refrigerator without making sure it is completely dry. Residual moisture in the drainage channels or on the contacts can cause a short circuit or the formation of a new ice block. Leave the doors open for another 30-60 minutes after wet cleaning for final ventilation.
Assemble the unit in the reverse order: install shelves, drawers and containers. Make sure that all guides click into place. Now you can connect the power cord to the outlet. Press the power button on the control panel.
After turning on, do not load products immediately. Let the refrigerator run idle for at least 2-4 hours (for models with LG run idle for at least 2-4 hours (for models with No Frost the time may be less, about 2 hours, but it’s better to be safe). During this time, the unit will reach the required temperature, and the automatic shutdown of the compressor will work.
Keep an eye on the first cycles of operation. If you hear unusual sounds, gurgling noises, or see that the refrigerator is not getting cold, check that the doors are closed tightly. If the problem persists, it is possible that the temperature sensor was dislodged during the washing process or the wire was damaged.
Common mistakes when servicing LG refrigerators
One of the common mistakes is the use of steam cleaners. The high temperature of the steam can deform the thin plastic of the internal panels and damage the electronic control unit, which is often located close to the walls of the chamber. It’s not worth risking expensive repairs for the sake of quick cleaning. control, which is often located close to the walls of the chamber. It’s not worth risking expensive repairs for a quick cleanup.
Another mistake is ignoring the operating instructions. The manual for your specific model LG may indicate specific requirements, for example, the use of only certain types of filters or specifics for removing shelves. Always check the official manual.
- 🚫 Do not use baking soda in large quantities on rubber seals - it dries out the rubber.
- 🚫 Do not wash the refrigerator while it is plugged in, even if you are just wiping down the shelves.
- 🚫 Do not leave the doors closed during drying - a “greenhouse” and a damp smell are formed inside.
⚠️ Attention: The interfaces of the control panels and the location of the elements may differ depending on the year of manufacture and series of the refrigerator. If you are not sure of the purpose of a particular button or part, check the official documentation on the manufacturer's website.
Regular and proper care of the refrigerator extends its service life and maintains food freshness. By following these simple rules, you will ensure your LG long and efficient operation, and also save on electricity and repairs.
How to remove a strong odor after defrosting?
Place activated carbon tablets or an open pack of soda inside the chamber for a day. A bowl of ground coffee or a slice of black bread also helps a lot.
Is it possible to wash the refrigerator without defrosting it completely?
If you have a model No Frost and there is no ice crust, you don’t have to do a complete defrosting. It is enough to quickly wash the shelves and wipe the walls, trying not to pour a lot of water. However, once a year, complete defrosting is still recommended to clean the drainage.
How long can you not turn on the refrigerator after washing?
The minimum waiting time after washing and assembly is 1 hour for the moisture to evaporate. After connecting to the network, before loading with food, another 2-4 hours should pass to enter the mode.
What is the best way to wash the inside of the refrigerator?
The best option is a warm solution of laundry soap or dishwashing detergent. For disinfection, you can use a weak solution of vinegar or hydrogen peroxide. It is better not to use chlorine-containing products.
What to do if, after turning on, the refrigerator hums more than usual?
Immediately after washing and loading food, the compressor may work more intensely. If the noise does not go away after a day or is accompanied by vibration, check whether the refrigerator is level and whether the pipes are touching the back wall.
