The situation when in the refrigerator Atlant only the freezer is working, and the main compartment is warm, is a classic symptom of a serious malfunction in the cooling system. Users often notice that food at the bottom begins to spoil while the freezer remains ice-free. This indicates that the refrigerant circulates, but does not reach the evaporator of the refrigeration compartment in the required volume or does not cool it to the required temperatures.
Such a malfunction cannot be ignored, since it indicates that the system is operating in emergency mode or with a critical load. The compressor may hum continuously, trying to compensate for the lack of cold, which leads to overheating. In some cases, the problem lies in a banal blockage of the capillary tube, in others - in a leak freon or failure of the control electronics.
Understanding the operating principle of the double-circuit or single-circuit system of your unit will help more accurately determine the source of the problem. In models with one compressor and system No Frost the cold is distributed forcibly, and fan failure can lead to the symptoms described. If you have a classic “crying” system, then the reason most often lies in the mechanical part of the cooling circuit.
Faults in the defrost system and ventilation
One of the most common reasons why the refrigerator compartment does not cool is a violation of the defrost cycle. In models with a Atlant The refrigerator compartment does not cool, the defrost cycle is disrupted. In models with the system No Frost or Frost Free system, ice builds up over time on the evaporator located behind the rear wall. If the defrosting system (heating element, timer or defrost thermostat) fails, ice blocks the air channels.
As a result, cold air physically cannot enter the main compartment, remaining locked in the freezer area. The compressor continues to work, creating the illusion of serviceability, but the cooling efficiency drops to zero. This is often accompanied by a characteristic hum or whistle if the fan begins to touch the ice crust.
For diagnostics, you need to check the following elements:
- ❄️ Defrost heating element —a heating element that can burn out and stop melting the ice.
- ⏱️ A timer or electronic control module is a device that does not send a signal to start defrosting.
- 🌡️ A defrost thermostat is a sensor that can “stick” in the “cold” position, prohibiting the heater from turning on.
⚠️ Attention: Forced defrosting of the refrigerator within 24 hours can temporarily solve the problem if the problem is an ice jam. However, if after switching on the situation repeats itself a week later, replacement of faulty components of the defrosting system is required.
How to check the defrosting heating element with a multimeter?
To check, you need to call the heating element for resistance. The normal value should be between 200 and 800 ohms. If the device shows infinity (open) or zero (short circuit), the element must be replaced. Do not forget to disconnect the refrigerator from the network before diagnosing!
Refrigerant leak and problems with the compressor
If you notice that the refrigerator Atlant works only in freezer mode, and the compressor is hot and runs non-stop, there is a high probability of a leak. refrigerant. Freon can escape through microcracks in the evaporator (especially if it is aluminum and corroded) or through poor-quality factory soldering.
If there is a partial pressure leak, the freon is only enough to cool the first section of the circuit - usually the freezer camera. The gas simply does not reach the refrigerator compartment or arrives already warm. In such cases, the compressor tries to compensate for the lack of pressure by constant operation, which leads to its rapid wear.
Symptoms of a freon leak include:
- 🔇 The compressor works constantly without turning off, but there is no cold in the main chamber.
- 🔥 The side walls of the refrigerator remain warm or cold, although they should be warming up.
- 💧 In the freezer, there may be a “snow coat” only at the entrance, and the freezing depth is insufficient.
It is impossible to eliminate the leak on your own, since the system must be evacuated and filled with gas in strict compliance with weight standards. Attempts to simply “add” freon without searching for the leak will only give a short-term effect.
Clogged capillary tube
Another technical reason why the refrigerator compartment does not work in Atlantalies in a clogged capillary tube. This thin copper tube serves as a throttle, creating a pressure differential to circulate the refrigerant. Over time, oil oxidation products, moisture (turning into ice plugs) or solid particles can accumulate inside it.
The blockage disrupts the circulation of freon: it accumulates in the condenser and cannot effectively pass into the evaporator of the refrigerator compartment. As a result, the freezer may freeze normally (or even too cold), but the temperature in the main compartment rises to room temperature. This condition is often confused with a leak, but diagnosis requires checking the pressure in the system.
The process of eliminating the blockage is complex and includes:
- Blowing the system with nitrogen at high pressure.
- Replacing the filter-drier, which must be changed whenever the circuit is opened.
- Evacuate and refill with refrigerant.
If the blockage is caused by moisture (hygroscopicity of the oil), then simple purging may not help, and repeated flushing of the system with special liquids will be required.
⚠️ Attention: Capillary blockage often appears cyclically: the refrigerator may normally refrigerate for a few days and then stop. This is due to the fact that the ice plug in the capillary can temporarily thaw when the compressor stops, and then freeze again.
Failures in the operation of sensors and thermostats
Modern refrigerators Atlant, especially series with electronic control, rely heavily on sensors. If the freezer is cold but the refrigerator compartment is not, the problem may be an incorrect reading from the main compartment temperature sensor. The electronics “think” that it is already cold there and does not issue a command for cooling, or vice versa, does not see the need for cold.
In models with mechanical control, the thermostat is responsible for regulation. If its capillary tube is incorrectly positioned or the mechanism itself is faulty, the contacts may not close to turn on the compressor until the temperature in the main chamber drops. But if the freezer freezes, it means that the compressor still turns on, but for insufficient time.
What to look for when diagnosing electronics:
- 📟 Error on the display - many models Atlant display fault codes (for example, F4, F5) indicating a specific sensor.
- 🔌 Oxidation of contacts - check the connectors of the sensors located inside the chambers.
- 🔄 Controller failure is a rare case when the “brains” of the refrigerator require flashing or replacement.
To check the sensors A multimeter is used in resistance measurement mode. As the temperature changes, the resistance of a working sensor should change smoothly. Abrupt changes or lack of response indicate a malfunction.
Comparative table of symptoms and causes
To make it easier to navigate possible malfunctions when the upper chamber in the refrigerator Atlant does not cool, use the table below. It will help narrow down the search for a problem before calling a technician.
| Symptom | Probable cause | Nature of compressor operation | Necessary actions |
|---|---|---|---|
| Ice on the back wall of the freezer, it’s warm in the refrigerator compartment | Malfunction of the defrosting system (heating element, timer) | Works cyclically, but the cycles are short | Defrosting, replacing the heating element or timer |
| The compressor is hot, it hums constantly, there is no cold anywhere or only at the beginning of the circuit | Freon leakage | Works without stopping | Searching for leaks, soldering, refilling |
| The freezer freezes heavily, the refrigerator compartment is warm, periodic switching on | Clogged capillary tube | Works with overload | Purge the system, replace the filter |
| The refrigerator turns on rarely, the main chamber is warm, the freezer is weak | Malfunction of the thermostat or sensor | It turns on rarely or at the wrong time | Replacing the thermostat/sensor |
Plan actions when a malfunction is detected
If you are faced with the problem that the refrigerator Atlant refrigerator does not work, do not panic. Following a clear algorithm will help preserve food and minimize damage to equipment. The first step should always be complete defrosting, even if the ice is not visually visible - it may be hidden inside the housing.
After defrosting, turn on the device and listen to the operation of the compressor. If it hums but doesn't start (clicking and buzzing), the problem may be with the start relay. If the engine runs smoothly, but there is no cold, check the integrity of the door seals. A loose fit of the refrigerator door leads to a constant influx of warm air, which the system cannot cope with.
Checklist for primary diagnostics:
☑️ Primary diagnostics of the refrigerator
It is important to check whether the drainage hole is clogged. If the moisture does not leave, it freezes and blocks the cold supply channels. You can clean it using a soft wire or a special brush.
⚠️ Attention: Technical characteristics and location of components may vary depending on the specific model Atlant. Always check the official instructions for your device, since the design of old and new series differs significantly.
When you need to call a specialist
There are a number of situations when self-repair is not only ineffective, but also dangerous. If after completely defrosting and checking the tightness of the doors the situation has not changed, most likely the problem lies “inside” the system. Opening the refrigeration circuit requires a license and special equipment.
A master is needed if:
- 🛠️ Replacement of the compressor is required - this is a complex procedure that requires overhauling the entire system.
- 🔥 There is a breakdown of the evaporator - often requires the installation of a sealed evaporator (“plates”) or expensive soldering.
- ⚙️ The electronic control module is faulty - professional diagnostics of the boards and flashing are required.
Attempts to solder the tubes yourself or replace freon “by eye” often lead to the final failure of the unit. The cost of such “repairs” subsequently exceeds the price of a new refrigerator.
In conclusion, a malfunction in which only the freezer in the refrigerator Atlant works can be solved in most cases. The main thing is to correctly diagnose the unit: be it a simple defrost, replacing a sensor, or complex circuit repair. Timely contact with specialists will extend the life of your equipment.
Frequently asked questions (FAQ)
Why, after defrosting, did the Atlant refrigerator stop cooling again in the main chamber?
This indicates that the reason is not ice traffic jam, but due to a technical malfunction. Most likely, one of the components of the defrost system (heating element, timer) has failed or there is a freon leak that appeared after the operating cycle. Diagnostics with a multimeter is required.
Is it possible to operate the refrigerator if the upper chamber does not cool?
It is highly not recommended. The compressor will work non-stop trying to compensate for the heat, causing it to overheat and burn out after a few days or weeks. It is better to turn off the device before repair.
How much does the repair cost if you need to refill freon?
The cost consists of the price for visiting, diagnostics, leak detection, soldering and the cost of the gas itself. Only a master can name the exact amount after inspection, since the amount of work depends on the location of the leak (evaporator, condenser or sealed part).
What does it mean if the compressor is hot and the tubes are cold?
This is a classic sign that freon is not moving anywhere. Either the compressor has lost compression (does not pump), or there is a solid blockage in the path of the refrigerant. In both cases, specialist intervention is required.
