How often and why to defrost the device
The defrosting time of the refrigerator is determined by the defrosting system installed by the manufacturer. If automatic air-drip or drip defrosting technology is used, manual defrosting is recommended once every 3-4 months.
The No Frost automatic defrosting system uses air defrosting. Moisture and ice are removed using fans that operate when the device is turned on. However, this method also requires disconnecting the self-defrosting refrigerator from the power supply every six months and cleaning it manually.
The technical data sheet contains the manufacturer's instructions about the need for defrosting and the time when it is recommended to do this. The defrosting mode is determined based on average statistical data. A universal guideline is the formation of ice: it is better to defrost the refrigerator if a thick crust of ice has formed before the time specified in the instructions.
Defrosting a refrigerator is not only freeing the freezer and refrigerator compartments from ice, but also hygienically treating the device. As a result, pathogenic microorganisms are destroyed and unpleasant odors are removed from the refrigerator chambers.
Main malfunctions of Indesit refrigeration units and methods for eliminating them
When a refrigerator breaks down, every owner is faced with the problem of storing food. If in winter you can still cope with this, albeit in non-standard ways, then in summer it always causes severe panic. Don't despair: perhaps the breakdown in your case can be fixed by yourself. See below for information on how to do this.
Scheme of the Indesit refrigerator and its necessity
Thanks to knowledge of the refrigerator’s operation circuit and some subtleties, you can correct the problem in the electrical circuit.
The refrigerator diagram shows in detail to a master with electrical skills where each contact and electrical element is located. Thanks to its accurate image, it is possible to eliminate the most serious damage: violation of the integrity of wire switching, as well as problems with the control module.
Ways to solve the problem if the starting relay is broken
A breakdown of the start relay is a serious problem, accompanied by strong heating of the air in the refrigerator or freezer compartment. The relay is responsible for the activity of the compressor, which drives freon through the tubes. When an increased temperature is observed in the device during switching on, one may suspect flooding of the relay contacts or the presence of carbon deposits. Such problems can be solved by replacing mechanisms, but you also need to know the operating principle of the part. More on this in the video below.
Why does the freezer refuse to work?
Problems with the freezer may be due to the inability to defrost on its own.
If you notice ice stains in the freezer compartment, while the appliance has NoFrost technology, there is something wrong with the system. The following circumstances may cause performance problems:
- If, when turned on, the freezer does not cool and does not freeze the loaded product, the relay may have failed or there is a refrigerant leak. With such a problem, experienced diagnostics of the device is required;
- the presence of a snow coat or smudges indicates that the problem is in the capillary tube, namely its obstruction or deformation. This effect can also cause the tube to move from its correct location during transport.
Built-in fan malfunction: symptoms and solution
You can check the malfunction of the Indesit refrigerator fan by connecting it directly to electricity. If it doesn't spin, it's time to replace it with a new one. It also happens that in some mysterious way ice forms on it - if you remove it, the device will continue its full operation.
In this review, we have discussed the most popular questions regarding the selection of refrigeration units from Indesit, as well as the principle of their operation and possible problems. If you still have questions about this, be sure to ask them in the comments, we will be happy to answer them.
Which is better: drip defrosting system or No Frost
Drip and No Frost devices are identical in their basic principles of operation. The walls of the units contain refrigerant - freon, flowing under pressure generated by the compressor. The physical state of the substance changes from liquid to gaseous; in parallel, the heating of the evaporator also changes, which reduces the temperature inside the refrigerator.
To find out which refrigerator defrosting system is better, we will determine the parameters for comparison:
- price;
- features of care and its simplicity;
- compliance with energy consumption class and noise level;
- preservation of the quality of products and the volume available for them in the refrigerator.
Advantages of drip systems compared to No Frost systems:
- win in the price range;
- presented in a wider range;
- devices do not require special care;
- consume less electricity, the unit operates less noisily.
If repairs are necessary, it is more difficult for craftsmen without special qualifications to understand the features of the complex No Frost scheme.
What you need to know before buying a refrigerator with a No Frost system
No Frost refrigerators have two defrosting methods - complete (the system is maintained in the freezer and refrigeration zone) and partial. In the second case, the freezer compartment is defrosted using the “No Frost” principle, and the refrigerator compartment is defrosted using the drip method. Ease of use and cost depend on this. Units with a powerful inverter motor operate quietly. If finances allow, it is better to purchase a two-compressor device. Its service life is longer. It controls the refrigerator and freezer compartments separately.
Today you can buy a home refrigerator with No Frost technology for up to 30,000 rubles. It is reliable and fully satisfies your needs. The unit is selected based on the main parameters: dimensions, functionality, noise level and energy consumption. Before purchasing, you should read the instructions for the selected model and read reviews about the models on Russian forums.
How to defrost a refrigerator with a manual defrost system
The drip-type automatic defrosting system involves clearing the refrigerator compartment of ice. This mode does not include the area of the freezer compartment, where ice accumulates depending on the load of food and the degree of use. In this area, prevention is carried out by manual defrosting every 1-1.5 years: the exact timing depends on the thickness of the ice layer in the chamber.
Sequencing:
- Empty the refrigerator of food by placing it in a cool, dark place for a while.
- To ensure a safe defrosting process, disconnect the household appliance from the mains.
- Place a tray or bowl where the thawed water drains.
- Defrosting time depends on the layer of accumulated ice and ranges from 1 to 10 hours.
- After the chamber is free of ice deposits, wipe all surfaces with a detergent solution to clean, disinfect and remove unpleasant odors.
- Wipe the entire interior dry.
LG GA-B459SEQZ
The 2-chamber unit is equipped with a panel in the upper part, the cold air from which quickly and evenly cools any food. Users have at their disposal spacious shelves made of tempered glass inside and on the door of the refrigeration unit, as well as transparent drawers.
Advantages
Pros of B459SEQZ:
- using the know frost system in both the refrigeration and freezer sections means dry freezing everywhere - you don’t have to get rid of ice build-up in the freezer or other compartments;
- the ability to remotely control the temperature in the unit by simply installing and using the SmartSync application on your mobile gadget;
- “natural freshness” technology is used - vegetables, fruits, etc. are not weathered, maintaining their natural taste and appearance for a long time.
This is a very quiet refrigeration appliance, which during operation emits a hum that does not exceed 36 dB (at the level of a muffled conversation). Moreover, its capacity is sufficient to freeze up to 12 kg of food supplies per day.
Flaws
In its price category, this is an excellent option without any drawbacks.
No Frost system and its varieties
The No Frost installation is used in household appliances operating on the principle of forced circulation. Here the evaporator is not located in the refrigerator compartment, but is mounted in the housing or located behind the back wall of the freezer or above it. One or more fans are used to circulate air.
The air is cooled by the evaporator as it leaves the chamber, then returned back through the openings. Wet condensation settles on the coldest parts of the walls of the cooling element. The heater turns on after the compressor stops, the frost from the evaporator thaws, all the moisture accumulates in the tray of the self-defrosting refrigerator, gradually evaporating.
What are the names of the types of such devices:
- Frost free – the system operates in one chamber;
- Full no frost – the system works in both the refrigerator and freezer compartments.
No frost system - advantages and disadvantages
The NoFrost system works without the formation of ice in the freezer and refrigerator compartments. They cool evenly as a result of constant air circulation, so food is stored longer. No Frost creates space for a “freshness zone” in the interior of the refrigerator compartment; here the fast freezing mode is activated.
The No Frost system also has disadvantages . Store products in airtight packaging: constant air flows create a “drying” effect. Sometimes this disadvantage turns into an advantage, since tightly packed products do not lose their attractive appearance, are stored longer, and do not emit odors.
Important! The cost of operating a device with a No Frost system will be higher than with a drip system. But having bought a No Frost refrigerator, you don’t have to worry about buying a new one for another 15-20 years.
Principle of operation
Refrigerators with automatic defrosting have a special technology that is used to get rid of excess ice. This type of device saves time associated with routine care.
The defrosting system consists of the initial formation of an ice crust followed by the evaporation of condensate, which passes along the back wall of the device into the tray. Moist cold is maintained inside the refrigerator, which ensures high-quality storage of food.
No Frost cooling technology is based on forced circulation of cold air without the formation of ice on the walls. The evaporator in the devices is located behind the back wall inside the housing or above the freezer compartment.
Behind it are fans that pump air into the chambers through special channels. Moisture in the device settles on the evaporator. Periodically turning off the blower and starting the heater will eliminate the layer of frost on the compressor. The resulting moisture is discharged into the tank through grooves and evaporates, closing the cycle.
In refrigerators with Low Frost technology, the evaporator circuit is located around the perimeter of the chamber, which ensures uniform cooling. The system is characterized by rapid defrosting and minimal ice formation. There is no need to defrost it for washing; you only need to disconnect it from the power supply once a year.
The operating principle of household appliances with a drip cooling system is simple. An evaporator is installed at the rear of the equipment, which is a serpentine tube mounted into the metal radiator plates. In operating mode, it heats up, the ice on the back wall of the device melts and, when the compressor stops, flows into the tank.

Drip defrosting system
Refrigerators from an affordable price range are equipped with a drip defrosting system. The principle of operation of this mode: the rear wall of the chamber is equipped with an evaporator - a cooling element. When the compressor operates, due to sub-zero temperatures, condensate ice forms on the rear wall of the chamber.
The ice gradually melts when the compressor is turned off, drops of water flow down and accumulate in a container above the compressor. As the compressor maintains a high temperature, the liquid evaporates.
Reference. The temperature settings and the overall chamber load determine the frequency of compressor activity.
Pros and cons of the drip defrosting system
The drip system is convenient because it prevents ice from forming in the refrigerator compartment. In low-quality appliances, the ice in the refrigerator still gets hot: you will have to get rid of it manually.
Important. The cost of the device is affected by the established defrosting method. When choosing an inexpensive refrigerator that does not require defrosting, pay attention to models that use a drip system.
