Modern household appliances, such as LG No Frost, require minimal intervention in their work, but regular hygiene remains a mandatory procedure for every owner. Many users mistakenly believe that the system No Frost completely eliminates the need for defrosting, but this is not entirely true. Although an ice crust does not form on the walls of the chamber, grease, bacteria and foreign odors do not disappear on their own, accumulating in the hidden corners of the unit.
The process of shutdown and subsequent cleaning LG refrigerator has its own technical nuances, ignoring which can lead to breakdown of the compressor or failure of the electronics. Unlike older models with a drip system, it is important here to properly prepare the equipment for “water procedures” so as not to damage sensitive sensors and fans. Below we will look in detail at how to safely stop the operation of the unit and bring it into ideal condition.
It is important to understand that defrosting in the context of systems with forced air circulation, this is more of a deep cleaning and sanitation than a fight against ice. The right approach will extend the life of your refrigeration equipment and ensure food freshness for many years. Let's start preparing.
⚠️ Attention: Before starting any work, make sure that you do not damage the integrity of the evaporator with sharp objects. In systems No Frost it is often hidden behind plastic panels, and its damage will lead to freon leakage and expensive repairs.
Why you need to wash a refrigerator with a No Frost system
Equipment owners LG often are surprised to learn that their unit still needs to be washed inside. The principle of operation No Frost is the circulation of dry cold air, which prevents the formation of ice on products and chamber walls. However, the same circulation carries microparticles of food, mold spores and odors throughout the internal volume, settling in hard-to-reach places.
Regular hygienic treatment is necessary to remove pathogenic microflora, which actively multiplies at positive temperatures in the refrigerator compartment. Fatty deposits, which are invisible to the eye, clog the air ducts over time and reduce the efficiency of heat transfer. If you do not clean it, refrigerator begins to work more intensely, consuming more electricity.
In addition, mucus and biofilm form over time in the drainage system, which removes condensate. This can cause an unpleasant musty odor that cannot be removed with conventional air fresheners. Only complete sanitation with a power cut allows you to get to hidden elements and eliminate the source of the problem.
- 🧼 Removing bacterial plaque and mold from internal surfaces.
- 🌬️ Cleaning the system air ducts No Frost from dust and grease.
- 👃 Elimination of persistent unpleasant odors absorbed into plastic.
- ❄️ Checking the condition of the seals and preventing them from drying out.
Preparing to disconnect: step-by-step algorithm
Before pulling the cord from sockets, you need to perform a number of preparatory steps that will preserve your products and protect your equipment. The first step should always be defrosting the contents: all perishable food should be removed. If you are planning a long-term wash, it is better to transfer the products into a thermal bag or temporary refrigerator so that they do not have time to deteriorate.
Next, you should clear the internal space of all removable elements. Shelves, drawers, egg trays and bottle holders all need to be removed. Plastic parts LG are quite durable, but at low temperatures (if you take them out to the balcony in winter) or under the influence of hot water they can become brittle. Therefore, wash them separately using warm water.
Only after the camera has been completely unloaded can you begin to manipulate the power supply. Disconnection It must be done strictly according to the instructions: first unplug the plug from the socket, and do not pull the wire. If access to the outlet is difficult, make sure that your hands are dry and the floor under your feet is not wet.
☑️ Preparing the refrigerator for washing
It is important to let the device stand turned off for a while before the active washing phase so that the temperature inside and outside aligned. This is especially true if you use warm water for cleaning to avoid thermal shock to the plastic elements.
How to properly turn off an LG refrigerator
The most correct and safest way to turn off LG refrigerator is to physically open the power circuit. On many modern models there is no “Off” button in the usual sense, which completely de-energizes the unit, leaving only the display active. To carry out work on cleaning we need a complete de-energization.
Press the power button on the control panel, if there is one, to go into standby mode, and then unplug the power plug. Some models Smart may require time to complete internal processes, but for washing it is enough to simply remove the cord. Make sure that the wire is not stretched or lying in water or detergents.
⚠️ Attention: It is strictly forbidden to pull the refrigerator by the door or the top of the case when turning it off. This may damage the compressor mounts or disrupt the housing geometry, which will lead to loose fitting of the doors.
After shutting down, leave the doors ajar. This is necessary so that the remaining cold comes out and the interior space is ventilated. In systems No Frost air circulates actively, and stagnant odor must be removed before applying cleaning agents.
What to do if the plug is in a hard-to-reach place?
If the outlet is located behind the refrigerator and there is no access to it, and you cannot move a heavy unit, you can use an extension cord with a switch (if it is connected through it) or carefully, with an assistant, pull out the refrigerator. Do not try to reach the plug by leaning over the top of the housing - this can cause injury.
The process of washing and cleaning the internal chambers
When the unit is turned off and empty, the main stage begins. To wash the inner walls LG it is best to use special household appliance products or a weak solution of baking soda. Aggressive chemistry with abrasive particles can scratch the plastic, into which dirt will then become clogged.
Pay special attention to the area around the air ducts. In models No Frost there are holes on the back wall through which cold is supplied. Water should not flow there in large quantities, as this may damage the fan or get on the electrical contacts. Wipe this area with a well-wrung out rag.
Do not forget about the rubber seal around the perimeter of the door. Black mold often accumulates in its folds. Carefully bend the rubber and wipe the hidden cavities with a cotton swab dipped in a disinfectant solution. The cleanliness of the seal directly affects energy efficiency your refrigerator.
- 🚿 Use warm water (about 30-40°C) to better dissolve fat.
- 🧽 A soft sponge will not leave scratches on glossy plastic LG.
- 🍋 Citric acid will help remove yellowness and refresh the smell.
- 💧 Wipe the surfaces thoroughly dry before turning them on.
After treating all surfaces clean water, be sure to wipe them with a dry cloth. Remaining moisture in the corners can become a breeding ground for bacteria immediately after switching on.
Cleaning the No Frost system and drainage
The system No Frost is the heart of your refrigerator, and it also requires care. Although getting to the evaporator without disassembling the housing is not recommended (and may void the warranty), accessible parts should be kept clean. The ventilation grilles on the back wall of the chamber can be gently vacuumed at minimum power.
A critical element is the drainage hole. It is located at the bottom of the rear wall of the refrigerator compartment. Condensate formed during defrost cycles escapes through it. If it becomes clogged, water will go inside the chamber or under the boxes of vegetables.
To clean, use a soft brush or a piece of soft cloth rolled into a rope. You can carefully pour a little warm water into the hole to check the permeability. If the water drains slowly, repeat the procedure. In some models LG access to the drainage channel is simplified, but you still need to act without fanaticism.
⚠️ Attention: Never use sharp objects (wire, knitting needles) to clean the drainage. You could puncture a tube or damage the defrost heater insulation, causing a short circuit or refrigerant leak.
Drying and first start after inactivity
After completing the water procedures, the drying stage begins. This is perhaps the most important point that is often ignored. You cannot turn on an LG refrigerator with wet walls - excess moisture will instantly turn into an ice crust on the evaporator, disrupting the operation of the system. Leave the doors open for at least 2-3 hours, and preferably overnight, so that all surfaces dry completely naturally. Make sure the room is warm and dry. Only after visual confirmation of the dryness of all components can the structure be reassembled. LG refrigerator with wet walls it is impossible - excess moisture will instantly turn into an ice crust on the evaporator, disrupting the operation of the system No Frost.
Leave the doors open for at least 2-3 hours, preferably overnight, to allow all surfaces to dry completely naturally. Make sure the room is warm and dry. Only after visual confirmation of the dryness of all components can the structure be reassembled.
Put the shelves and drawers in place, check the reliability of their fixation. Then connect the unit to the network. Please note that the compressor may not start immediately, but after 10-15 minutes - this is normal for modern control systems. It is recommended to load products 2-3 hours after start-up, when the operating temperature conditions have been established.

Frequently asked questions (FAQ)
Is it possible to wash an LG refrigerator without unplugging it?
It is strictly not recommended. Water and detergents are conductors of electricity. Even a drop that gets onto the contacts of the control panel or inside the case can cause a short circuit. In addition, a running compressor and fans create vibration, which interferes with quality cleaning.
How often do you need to defrost a No Frost refrigerator?
Full defrosting with disconnection from the network for the system No Frost is recommended to be carried out 1-2 times a year. However, shelves should be wiped down and food checked weekly. If you notice the appearance of ice in the chamber or an unpleasant odor, the procedure must be carried out unscheduled.
What should not be used to wash the internal surfaces of the refrigerator?
It is prohibited to use abrasive powders, high concentrations of chlorine-containing bleaches, acetone, gasoline and other aggressive solvents. They can damage the antibacterial coating LG Hygiene Fresh+ (if the model has it) and spoil the plastic, making it brittle.
What should you do if the refrigerator makes a lot of noise after turning it on?
If the noise appears immediately after washing, check whether water has gotten into the fan area or onto the compressor tray. Also make sure that the refrigerator is level and not touching walls or furniture. If the noise does not subside within 24 hours, contact the service center.
Is it necessary to lubricate the seal after washing?
Yes, this is a useful procedure. After drying, the rubber seal can be wiped with a special rubber care product or a weak glycerin solution. This will prevent it from drying out and cracking, maintaining elasticity and tightness refrigerator compartment.
