Modern models with the system No Frost have saved users from the need for monthly manual defrosting, but this does not mean that the unit does not require attention at all. Many owners mistakenly believe that the absence of ice on the walls of the chamber frees them from carrying out preventive work, which ultimately leads to the appearance of an unpleasant odor, reduced cooling efficiency and even compressor breakdowns.
Regular care of the internal and external surfaces, as well as hidden elements of the air circulation system, is the key to long-term operation of your equipment. Unlike the drip system, here ventilation ducts and the evaporator are located behind plastic panels, where it is not so easy to reach, but their condition cannot be ignored. Proper operation will keep food fresh and energy saved.
In this article we will analyze all the stages of proper maintenance, from preparing tools to the intricacies of caring for seals and ventilation holes. You will learn why you can’t use aggressive chemicals and how often you really need to do general cleaning so that your LG, Samsung or Indesit serves for decades.
Frequency and preparation for maintenance
Optimal frequency of general cleaning of a refrigerator with a system No Frost is once every 3-6 months, depending on the intensity of use and the number of stored products. If you notice the appearance of foreign odors or visible dirt, the procedure should be carried out unscheduled, without waiting for the planned date. Before starting work, you must completely empty the chambers of their contents.
For high-quality cleaning, you will need a basic set of tools and products that will not damage the internal coating. It is strictly forbidden to use abrasive sponges, metal scrapers or aggressive solvents, as they can damage plastic panels and the antibacterial coating.
- 🧽 Soft sponge or microfiber for wiping surfaces.
- 🧴a detergent (specialized for refrigerators or a weak soap solution).
- 🥣 A container with warm water for rinsing rags.
- 🔦 A flashlight for inspecting hard-to-reach places and ventilation grilles.
⚠️ Attention: Never turn on the refrigerator immediately after washing if a large amount of water has got inside. Allow the equipment to dry completely for 1-2 hours to avoid a short circuit in the electrical circuit.
It is also important to prepare a place for placed products. While you are cleaning, it is better to take the products to a cool place or put them in a thermal bag with ice so as not to disturb temperature conditions storage. If this is not possible, try to complete all procedures as quickly as possible.
Rules for defrosting the No Frost system
Although the technology No Frost involves automatic removal of moisture and the absence of ice in the chamber, it is recommended to carry out a complete defrost once every year and a half. This is necessary so that the evaporator, hidden behind the back wall, is completely freed from microscopic ice crystals, which over time can be compressed into an ice coat.
The defrosting process is simple: unplug the device from the power supply, open the doors and leave it alone for at least 12-24 hours. Do not try to speed up the process by using a hairdryer or placing a bowl of boiling water inside - a sharp temperature change can lead to deformation of the plastic or damage to the refrigerant tubes.
Why should you not chip ice with a knife?
Mechanical impact with a sharp object on a frozen evaporator can lead to breakdown of freon tubes. Repair in this case will be difficult and expensive, often requiring replacement of the compressor.
During defrosting, a significant amount of water may leak out of the drainage hole, so prepare rags or place a container in advance. Once all the ice has melted, thoroughly wipe all surfaces dry. Pay special attention to the area where condensation usually accumulates.
- ❄️ Unplug the equipment and remove all shelves.
- ⏳ Leave the doors open for a day to completely evaporate moisture.
- 💧 Wipe the internal surfaces with dry with a rag.
- 🔌 Turn on the device only after it has completely dried and checked the drainage.
Cleaning the drainage system and ventilation ducts
One of the most common reasons for the appearance of puddles under the refrigerator or inside the chamber is clogging drainage hole. In the No Frost system, the condensate formed on the evaporator must flow freely into a special tray above the compressor, where it safely evaporates. If crumbs or mold get into the hole, water begins to overflow.
To clean, use a soft brush or a special flexible wire with a cotton swab at the end. Carefully insert the tool into the hole, usually located on the back wall of the chamber, and make several rotational movements. After mechanical cleaning, it is recommended to rinse the canal with warm water from a syringe or syringe without a needle.
| Problem | Probable cause | Solution method |
|---|---|---|
| Water at the bottom of the chamber | Clogger drainage hole | Cleaning with a brush and rinsing with water |
| Ice coat on food | Loose door fit | Adjusting hinges or replacing seal |
| Alien noise | Foreign object in the fan | Removing the back panel and removing debris |
It is also worth checking the ventilation grilles through which cold air circulates throughout the chamber. If they are clogged with dust or food packaging, air circulation it is disrupted, which forces the compressor to work with increased load. Blow out the holes with a dry soft brush or use a vacuum cleaner at minimum power.
☑️ Cleaning the drain
Care of seals and external surfaces
The rubber seal around the perimeter of the door is the first barrier that keeps the cold inside the chamber. Over time, grease, crumbs and mold accumulate on it, leading to loss of elasticity and a loose fit. If the door does not close tightly, warm, moist air enters the chamber, causing increased frosting of the evaporator. Wipe the seal with a soft cloth soaked in a weak solution of vinegar or citric acid once a month. This will help remove greasy deposits and prevent bacterial growth. After wet cleaning, be sure to wipe the rubber dry. evaporator freezing.

⚠️ Attention: Avoid using oils, petroleum jelly or silicone lubricants to “revitalize” rubber unless recommended by the manufacturer. Some substances can cause swelling or cracking of the sealant material.
The external surfaces of the refrigerator also require maintenance, especially if the equipment is installed in a kitchen with a gas stove, where microparticles of fat may be floating in the air. For stainless steel cases, use special polishes that prevent the appearance of fingerprints (fingerprints) and maintain shine.
Hygiene of internal shelves and drawers
Glass shelves and plastic drawers in refrigerators Bosch, Electrolux and other brands often have a complex shape and many edges where bacteria like to accumulate. They should be washed separately from the body, in warm water with the addition of a mild detergent.
Do not place hot glass shelves immediately after washing under cold water or on cold glass - the thermal shock may crack the material. Let the parts warm up to room temperature. Also watch the guides along which the shelves slide out: they also need to be periodically wiped to remove sticky deposits.
Storage areas for vegetables and fruits require special attention. Even if you use the system No Frost, the remains of rotten vegetables can become a source of mold, the spores of which will be carried by the fan throughout the chamber. Regularly sort through supplies and wash boxes with disinfectant.
- 🥬 Remove boxes completely for thorough washing on all sides.
- 🚿 Use warm water, avoiding sudden temperature changes for glass.
- 🦠 Treat once a quarter surface with a solution of soda or vinegar.
- 🌬️ Before reinstalling, make sure that all parts are completely dry.
Frequent errors during operation and maintenance
Many users inadvertently shorten the service life of their equipment by making a number of common mistakes. For example, loading hot foods into the chamber forces the cooling system to work at its limit, which leads to rapid wear of the compressor and the formation of excess condensation.
Another common mistake is storing food without packaging. In the No Frost system, air constantly circulates, and if meat or fish are left open, their smell will be absorbed into plastic parts and rubber seals, which is then very difficult to get rid of. Always use containers or cling film.
You should also not completely fill the freezer to capacity. Although the cold is maintained well, the lack of free space disrupts the proper circulation of air flow, which can lead to uneven cooling and the formation of ice plugs in the channels.
Control of compressor operation and noise
Modern inverter compressors operate much quieter than older models, but they are not completely silent. However, the appearance of new sounds - humming, gurgling, clicking or whistling - should alert you. Gurgling is often normal (refrigerant is leaking), but a loud hum may indicate problems.
If you notice that the refrigerator has started to work without interruption or, conversely, turns on too rarely, check the temperature settings. Perhaps the settings have gone wrong, or there has been a power surge. In such cases, a full cycle of rebooting the system helps: disconnecting from the network for 15–20 minutes.
Why does the refrigerator hum after installation?
If you have just delivered and installed the refrigerator, it needs time (from 2 to 4 hours), so that the refrigerant is distributed throughout the system and the oil flows into the compressor. Turning on before this time may cause damage. Also make sure that the equipment is level and does not touch the cabinet walls or other objects.
Is it possible to wash the outside of the refrigerator with a steam generator?
Using a steam generator for external cleaning is only permissible for metal surfaces, and then only with caution. It is strictly forbidden to direct a jet of steam at the ventilation grilles, control panel or door gaps - moisture under pressure will penetrate inside the electronics and cause corrosion of the contacts.
What to do if there is a mold smell?
The smell of mold often indicates that spores have entered the ventilation system. In addition to cleaning the camera, try placing an open container of activated carbon, baking soda, or a special odor absorber inside. If the smell does not go away after thorough cleaning, there may be mold in the drainage hose and it will need to be disassembled.
Regular maintenance of your refrigerator is not just a matter of cleanliness, but also saving the family budget. Timely cleaning of drainage and checking seals allows you to avoid costly repairs and replacement of components. Remember that even the most advanced technology requires a caring attitude and attention to detail.
