A sudden stop in the operation of refrigeration equipment always becomes an unpleasant surprise for the owner. It is especially disappointing when equipment from a Belarusian manufacturer Atlant, which has proven itself to be reliable and durable, ceases to perform its functions. Products begin to deteriorate, a foreign smell appears in the room, and a puddle forms on the shelves. In such a situation, the main thing is not to panic, but to consistently analyze the situation in order to understand the scale of the problem.
Primary diagnostics allows you to determine whether the malfunction can be fixed on your own or whether you need to call a technician. Often the cause of breakdown is trivial things, such as voltage surges or incorrect installation. However, there are also more serious ones that require the intervention of professionals. Understanding the principles of operation of the unit will help you quickly navigate the symptoms. technical faultsrequiring professional intervention. Understanding the operating principles of the unit will help you quickly navigate the symptoms.
In this article we will consider in detail all possible scenarios for the failure of brand equipment Atlant. We will analyze both electrical circuits and mechanical components, including the compressor and refrigerant circulation system. Carefully studying the symptoms will help you save time and money on diagnosis.
⚠️ Attention: Before starting any inspection, be sure to disconnect the refrigerator from the power supply. Working with live electrical appliances is strictly prohibited and dangerous to life.
Power supply problems and power surges
The very first and most obvious reason why a refrigerator may not work Atlantlies in the power supply system. Household appliances are sensitive to the quality of the supplied electricity. If your network experiences frequent power surges, this may cause protective mechanisms to trip or damage internal components.
Check that the power light on the control panel is on. If the light does not light up, try plugging another working device into the same outlet, such as a lamp or hair dryer. This will eliminate the malfunction of the outlet itself or the circuit breaker in the panel.
Modern models are equipped with electronic controls that can block startup after a power surge. In older models with mechanical control, the problem may lie in oxidation of the contacts or blown fuse. Electrical circuit must be intact for normal operation.
- 🔌 Check the tightness of the plug to the socket and the absence of carbon deposits on the contacts.
- ⚡ Make sure that the electricity in the house has not been cut off or the plugs have not been knocked out.
- 🔋 Inspect the network cable for mechanical damage and kinks.
Faults of the thermostat and temperature sensors
Thermoregulator (thermostat) - This is the “brain” of the refrigerator, which controls the temperature inside the chambers. It is this that commands the compressor to turn on when it gets too warm and turn off when the desired level of cold is reached. If the refrigerator Atlant does not work or, on the contrary, freezes continuously, there is a high probability of failure of this element.
In models with mechanical control, the thermostat is a device with a bellows and a capillary tube. If there is a breakdown, the contacts inside may “stick”, and the compressor simply does not receive a signal to start. In units with a system No Frost and electronic control, air sensors are responsible for this.
You can diagnose a malfunction of the thermostat by closing its contacts directly (only for experienced users!). If after this procedure the compressor starts working, then the problem is in the regulator. It is better to replace it with original spare parts Atlantto avoid problems with calibration.
How to check a thermostat with a multimeter?
To check, you need to remove the thermostat, put the multimeter in dial mode and connect the probes to the contacts. At room temperature the chain should ring. If you place the sensing element in cold water with ice, the circuit should open (stop ringing). Lack of response indicates a malfunction.
It is important to consider that in two-chamber models there may be two thermostats: one for the refrigerator compartment, the other for the freezer. If only one of the compartments does not cool, the problem can be localized precisely in the corresponding sensor. Control system Should work synchronously.
Failure of the compressor and start relay
The compressor is the heart of the refrigeration circuit, providing refrigerant circulation. If you hear a quiet hum or click, but the refrigerator Atlant does not start and does not cool, perhaps the problem lies in the starting relay or motor windings.
The starting relay is responsible for supplying a starting pulse to the engine. Over time, the contacts inside the relay burn out and it ceases to perform its function. This is one of the most common reasons why equipment stops working. Replacing the relay is an inexpensive procedure and is often performed independently.
A more serious situation is the combustion of the compressor windings or its mechanical “wedge”. In this case, the engine hums, trying to start, but the shaft does not turn. If you do not stop such a unit in time, the wiring may burn out. Starting the compressor in this state it is impossible without repair.
☑️ Diagnostics of the compressor
There is also a possibility of freon leakage, which is why the compressor is running idle or shuts down due to overheating. If the tubes are hot and there is warmth inside, this is an alarming symptom. In such cases, professional pressure diagnostics in the system is required.
Failures in the defrost system (for No Frost models)
Refrigerators Atlant with system No Frost less demanding on defrosting, but their design is more complex. The key element here is the evaporator defrost system. If it fails, the evaporator becomes overgrown with a “coat” of ice, which blocks the cold air circulation channels.
As a result, the fan cannot drive air through the radiator, and it becomes warm in the chambers, although the compressor itself can work continuously. Most often, the defrost heating element, defrost sensor or timer (control unit) breaks down.
This problem can be determined by the presence of ice on the back wall inside the freezer (under the plastic panel). If you see massive icing there, and the fan is humming but not blowing, the defrost system is faulty. It is required defrosting and replacement of burnt elements.
| Symptom | Possible cause | Necessary actions |
|---|---|---|
| Ice on the back wall | Faulty defrost heating element | Replacing the heating element |
| Fan does not spin | Icing of the blades or motor failure | Defrosting or replacing the fan |
| The compressor runs without stopping | Heat transfer disturbance due to ice | Checking the defrost sensor |
| Water under the refrigerator | Clogged drainage channel | Cleaning the drain |
Clogged capillary tube and freon leak
Circulation of refrigerant (freon) in a closed circuit is the basis of the operation of any refrigerator. If a blockage occurs in the system (usually at the junction of the capillary tube into the filter drier) or a leak, the cold production stops. The compressor may work, but there will be no effect.
When freon leaks, the compressor often works silently or turns off, since the sensors do not record the required pressure. When clogged, the engine may hum more than usual, trying to push gas through the plug. Pressure in the system is a critical parameter.
It is impossible to eliminate these faults on your own. Special equipment is required to evacuate the system, refill with freon and search for leaks using a leak detector. Attempts to simply “add gas” without eliminating the cause will lead to repeated breakdown.
⚠️ Attention: Freon is a chemical that requires careful handling. Do not attempt to open or solder copper tubes yourself without skills and eye protection.
Often a sign of a leak or blockage is uneven cooling: one corner of the freezer is cold, and the other is warm. Or the condenser grille on the rear wall is only partially heated. This is a sure sign that refrigerant circulation refrigerant circulation is broken
Mechanical damage and wear of seals
This is not always the reason that the refrigerator Atlant does not work properly, lies in the electrics. Mechanical factors play a huge role. A damaged door seal allows warm air inside, causing the compressor to wear out, which ultimately leads to overheating and shutdown.
Check the integrity of the rubber around the perimeter of the door. It should fit snugly to the body. If the rubber becomes stiff, cracked, or deformed, it must be replaced or an attempt can be made to restore elasticity (temporarily). Also check the door hinges - if they are skewed, the tightness is broken.
Another factor is the location of the refrigerator. If it is placed close to a wall or furniture, the ventilation of the condenser is disrupted. The engine overheats and the thermal protection relay is activated, turning off the unit. Air gap required for normal operation.
- 🚪 Check whether the door closes tightly (test with a sheet of paper).
- 📏 Make sure that the distance to the wall is at least 5-10 cm.
- 🧊 Inspect the shelves and drawers for cracks that interfere with circulation.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator hum, but does not freeze?
This is a classic sign of a malfunction of the start relay, compressor or freon leak. The engine tries to start, but cannot. It is also possible that the capillary system is clogged. Diagnostics by a technician is required.
What to do if the refrigerator does not turn on after defrosting?
Let it stand unplugged for another 3-4 hours. Moisture may have gotten into the electrical contacts. If after complete drying the equipment does not work, check the socket and plug. In the worst case, the compressor could burn out due to starting with ice residue.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require the procedure 1-2 times a year. Systems No Frost i Frost Free do not need forced defrosting, but a preventive shutdown once a year for washing and drying will benefit them.
Is it possible to repair the Atlant refrigerator yourself?
Replacing a light bulb, thermostat or You can make the seal yourself. Repairing the compressor, refilling with freon and soldering pipes should only be performed by a certified specialist with a license.
