Owners of household appliances of the brand Atlant often face a situation when moisture begins to accumulate on the inner walls of the chamber or under vegetable drawers. This condensate can turn into a puddle, spread onto the kitchen floor, or freeze in the form of a snow coat, interfering with normal operation. Condensation is not just water, it is an indicator of a violation of heat exchange or operation of the moisture removal system, ignoring which leads to failure of expensive components.
The appearance of moisture inside the sealed volume of a refrigerator is contrary to the laws of physics if the system is working properly. Moisture gets there along with food, humid air when doors are opened or as a result of melting ice. In normal mode, this water should evaporate or be discharged into a special tray. If you notice that Atlant refrigerator cries, you need to carry out diagnostics, starting with simple actions and ending with checking complex electrical circuits.
In this article we will analyze in detail the mechanical and technical causes of the problem. You will learn how to distinguish a banal clogged drain hole from a serious malfunction of the compressor or No Frost system. Timely detection a source of moisture will help you avoid costly repairs and food spoilage.
Violation of tightness and problems with the seal
The most common and easily removable reason why condensation appears in the Atlant refrigerator lies in the violation of the seal of the chamber. Warm indoor air contains water vapor. When this steam penetrates inside through a loosely closed door, it instantly cools down on the cold walls and falls out in the form of dew. Sealing rubber (cuff) loses elasticity over time, cracks or deforms, ceasing to perform its function.
Often the problem does not arise due to wear of the rubber itself, but due to contamination of the magnetic tape or profile on which it is glued. Crumbs, sticky stains from syrup or grease prevent the door from sealing tightly. It is also worth checking the hinges: if they are skewed, the door will be skewed and the seal will be compromised even with a new seal. In models with a system No Frost a loose fit leads to increased freezing of the evaporator, which ultimately causes a leak.
To fix the problem, you must thoroughly wash and degrease the surface of the seal and the mating part of the housing. If the rubber is damaged, it should be replaced. In some cases, treating the seal with glycerin or silicone grease helps, which restores its softness and elasticity.
☑️ Diagnosis of tightness
Clogging of the drainage hole and drainage system
If your refrigerator operates on the drip principle (crying evaporator), then the melt water is drained through a special drainage hole located on the back wall of the chamber. The water flows down a groove into a tube leading to a tray above the compressor, where it evaporates. If debris, crumbs or mold accumulates in this hole, water plugforms. The water stops draining and begins to overflow over the edge of the groove, getting onto the shelves and products.
In models with a system No Frost the drainage system is more complicated. Melt water is discharged from the evaporator, hidden behind a plastic panel. If the drainage channel inside the cabinet is frozen or clogged with ice, the water has nowhere to go and flows through the air ducts directly into the refrigerator or freezer. This is often accompanied by the formation of an ice block at the bottom of the freezer.
How to clean the drainage without disassembling the refrigerator?
Take a soft wire (for example, from a charger phone) or a special brush. Carefully insert it into the drainage hole and make several rotational movements. Then pour 50-100 ml of warm (not boiling water!) water into it to wash away any remaining dirt. If the water leaves with a characteristic gurgle, the problem is solved.
To prevent blockages, it is recommended to periodically check the cleanliness of the drainage gutter. Use warm water helps to dissolve fatty deposits, which often cause debris to stick. If simple cleaning does not help, it is possible that the tube is pinched or burst inside the housing, which requires more serious intervention.
Malfunctions of the defrost system in No Frost refrigerators
In Atlant refrigerators with the system No Frost condensation is often a consequence failure in the automatic defrost cycle. This system includes a heating element (heating element), defrost sensor and timer (or electronic control module). If one of these elements fails, a “coat” of ice builds up on the evaporator. When the compressor is turned on, this ice begins to melt, but the drainage cannot cope with the large volume of water, and it flows out.
It breaks most often Defrost heating element. It stops heating and the evaporator becomes overgrown with ice. The defrost sensor may also get stuck, which “does not see” that the ice has melted and prematurely turns off the heating. In more rare cases, the timer is faulty and simply does not give the command to turn on the defrost mode. As a result, the refrigerator operates in constant freezing mode, ignoring the need to reset the ice.
Diagnostics of these elements requires a multimeter to check the resistance of the circuits. The heating element should “ring” (have resistance), and the sensor should change its readings depending on the temperature. Replacing the heating element yourself is possible if you have access to the evaporator, but often partial disassembly of the inner lining of the chamber is required.
⚠️ Attention: Before checking the electrical elements (heating element, sensors), be sure to disconnect the refrigerator from the mains! Working with live electrical wiring is dangerous to life.
The influence of ambient temperature and operating mode
Sometimes the cause of condensation lies not in a breakdown, but in incorrect operating conditions. The Atlant refrigerator, like any other equipment, is designed to operate in a certain climate class. If the device is installed in an unheated room where the temperature drops below +10°C, or, conversely, next to a hot stove, the thermostat may not work correctly. This leads to an imbalance of temperatures and dew.
The frequency of door openings also plays an important role. If you open the refrigerator often and for a long time, a large amount of moist air enters inside. The system does not have time to quickly dry this air, and the moisture settles on the coldest surfaces - usually the back wall and corners of the chamber. This is especially true in the summer, when indoor humidity is high.
Another factor is the installation of hot products. If you put a pot of warm soup in the chamber, it will begin to actively evaporate moisture. This moisture is instantly preserved on the walls in the form of condensation. Thermoregulator will try to cool the chamber, working hard, but the amount of water may exceed the capabilities of the drainage system.
| Factor | Influence on condensation | Solution |
|---|---|---|
| High humidity in the room | Increased formation of dew when opening the door | Ventilating the kitchen, checking the hood |
| Installation near a radiator | Overheating of the compressor, cycle violation | Moving the refrigerator to a cooler place |
| Hot foods | Sharp jump in humidity inside the chamber | Cool food to room temperature before loading |
| Open door | Intake of a large volume of moist air | Make sure the closure is tight, do not keep it open for long |
Mechanical damage and manufacturing defects
Physical damage to the housing or internal elements cannot be ruled out. Cracks in the plastic drainage channel on the back wall are causing water to flow past the drainage hole and onto the shelves. Such cracks can form due to careless defrosting (if you picked the ice with a knife) or due to the aging of the plastic, which becomes brittle.
In rare cases, there are factory defects or poor-quality repairs in the past when the thermal insulation of the walls was damaged. If a “cold bridge” has formed in the wall of the refrigerator, then the temperature in this place will be significantly lower than around it. Moisture from the air will condense at this point, forming a local puddle or ice. This is often visible visually as a wet spot on the outer or inner wall.
If you find mechanical damage to the gutter, you can try to seal it. For this, food grade silicone sealant or epoxy resin approved for contact with food is used. It is important to thoroughly degrease the surface before application and allow the sealant to dry completely before turning on the appliance.
⚠️ Attention: When using sealants, make sure they are completely dry and odorless before loading products. Chemical vapors can be absorbed into food.
Do-it-yourself diagnostics and elimination methods
To understand why there is condensation in the Atlant refrigerator, you need to use the method of elimination. Start with a visual inspection: check the seal, look into the drainage hole, estimate the amount of ice in the freezer. If external causes are excluded, you will have to move on to more complex diagnostics. To check the system No Frost you will need to remove the back panel in the freezer.
After removing the panel, assess the condition of the evaporator. If it is covered in ice and the heating element is cold, the problem is in the heater or its power circuit. If there is no ice, but water still flows, check the integrity of the drainage tube inside the housing. Sometimes the tube jumps off the fitting and water flows past. In such cases, disassembling the inside of the refrigerator is required.
Algorithm for checking the defrost heating element:1. Disconnect the refrigerator from the network.
2. Remove the back panel in the freezer.
3. Find the heating element (usually this is a curved tube at the bottom of the evaporator).
4. Remove the terminals from the heating element.
5. Ring the heating element with a multimeter in resistance measurement mode (Ohm).
6. If the device shows "1" or "OL" (open) - the heating element is faulty.
Do not forget that some Atlant models have specific design features. For example, in dual-compressor models, problems with condensation in one chamber may be independent of the operation of the other. Always check the technical documentation for your specific model.
⚠️ Attention: Specifications and location of elements may vary depending on the year of manufacture and series of the refrigerator. Always check the assembly diagram in the manufacturer's official instructions before starting disassembly.
Frequently asked questions (FAQ)
Why does condensation appear only in summer?
In summer, indoor air humidity is much higher than in winter. Each time the door is opened, more water vapor enters. If the drainage system is working at its maximum capacity or the seal is not ideal, in the summer this manifests itself in the form of condensation, which was not there in the winter.
Is it possible to use a refrigerator if it is “crying”?
For a short time - you can, collecting water with a rag. However, constant humidity creates ideal conditions for the growth of bacteria and mold, which is harmful to food and health. In addition, water can get on electrical contacts or cause corrosion of metal parts of the case.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require cleaning from ice when its layer reaches 3-5 mm (usually every 3-6 months). Systems No Frost and "Crying Evaporator" do not require manual defrosting, but preventive washing with disconnection from the network is recommended 1-2 times a year.
What to do if the drainage hole is frozen?
Do not try to break through the ice with a knife or wire - you can damage the plastic or handset. It is best to defrost the refrigerator completely (for 10-12 hours) or carefully pour warm water from a syringe into the hole until the ice melts.
