Refrigerators of the Belarusian brand Atlant have enjoyed well-deserved popularity in the post-Soviet space for many years due to their affordable price and proven design. However, like any complex household appliances, these units are subject to wear and tear and can fail at the most inopportune moment. Understanding the nature of typical malfunctions allows the owner to quickly react and minimize product losses.
In this article we will examine in detail the most common problems faced by users of these refrigeration units. You will learn how to independently carry out initial diagnostics, which components to pay attention to first, and in which cases calling a specialist becomes an absolute necessity. A competent approach to operation extends the life of the appliance.
Statistics from service centers show that the lion's share of calls are related to temperature violations or the appearance of extraneous sounds. Often the cause is a simple failure to comply with operating rules or natural wear and tear of consumables. Let's look at the main symptoms and methods for eliminating them so that you can return the equipment to working order.
Violation of the temperature regime and compressor operation
The most common complaint from owners is that the refrigerator has stopped freezing or, conversely, has begun to freeze food. If you notice that it is warm in the main chamber, but a “fur coat” has formed in the freezer, or the equipment works non-stop, trying to gain temperature, the problem lies in the refrigerant circulation system. Compressor it may hum constantly, but not give cold.
In models with one compressor and system No Frost or drip defrosting, the thermostat often fails. This device monitors the temperature of the evaporator and gives a command to turn the motor on or off. If the sensor is “stuck” in the “on” position, the unit will wear out, forming ice build-ups.
Another critical malfunction is a freon leak. If you see that the condenser (grid at the back) is cold and the motor is running, most likely the gas has simply escaped through a microcrack. In this case, it is necessary to search for the location of the leak, seal and refill the system.
- 🔴 Freon leak: requires professional equipment for searching and refilling.
- ❄️ Malfunction thermostat: easily changed independently if you have the skills.
- ⚙️ Clogged capillary tube: often accompanied by loud gurgling and lack of cold.
- 💨 Leaking seal: leads to constant entry of warm air and freezing.
It is important to understand that compressor is the heart of the refrigerator. If it overheats and burns out, replacement will be quite expensive. Therefore, at the first signs of incorrect operation (long pauses or continuous operation), it is worth inspecting the system.
Problems with the defrosting system and ice formation
In refrigerators Atlant with the system No Frost or a “crying” wall, the proper functioning of the defrost system is critically important. If you find that the back wall of the refrigerator compartment is covered with a layer of snow, and there is water under the vegetable drawers, then the defrosting cycle is broken. The water does not have time to drain into the evaporator and freezes or leaks out.
The main culprits here are Defrosting heating element, the timer or fuse. The heating element may simply burn out over time, ceasing to heat the evaporator. The timer, in turn, may get stuck in the cooling mode without starting the defrosting mode. In models with electronic control, this process is responsible for the control module, which could fail due to a power surge.
How to check the defrosting heating element with a multimeter?
To check, you need to get to the evaporator (usually behind the back panel in the freezer). Disconnect the wires from the heating element and test it with a tester in resistance measurement mode. If the device shows a break (one or infinity), the heating element is faulty and requires replacement. The normal resistance of a working heating element is usually in the range of 200-400 Ohms.
Often users ignore small puddles under the refrigerator, considering it condensation. However, the regular appearance of water is a signal that the drainage hole is clogged with crumbs or ice. Cleaning the drainage with a soft wire or a syringe with warm water often solves the problem without calling a technician.
☑️ Diagnostics of the defrost system
Extraneous noise, vibration and hum during operation
A refrigerator is not a silent appliance, but the nature of the sounds can say a lot about its condition. If you hear a loud humming, knocking or whistling noise that was not there before, an inspection is necessary. Vibration The cabinet is often transmitted to the floor or furniture, increasing the effect.
One common cause of noise is improper installation. If the unit is not level, the compressor during operation causes resonance of the entire housing. Also, the source of sound can be tubes that become loose over time and begin to touch each other or the walls of the cabinet. In this case, it is enough to carefully straighten the tubes or install rubber gaskets.
⚠️ Attention: If you hear a loud metallic clanging or knocking immediately after turning on the compressor, this may indicate a destruction of the motor mount inside the casing or a problem with the valves. Further operation in this mode will lead to complete failure of the unit.
The whistling sound is often produced by itself compressor when trying to start, if there is high pressure in the system or there are problems with the starting relay. The humming of a fan in systems No Frost may indicate that ice has frozen on its blades or the grease of the bearings has dried out.
- 🔊 Loud hum: Check whether the refrigerator is touching a wall or cabinet.
- 🔨 Knocking at start-up: a sign of a malfunction of the starting relay or compressor.
- 🌬️ Fan noise: ice freezing on the blades or bearing wear.
- 📉 Gurgling: normal sound of freon flowing or a sign of blockage.
To eliminate vibration, use a building level. Adjust the legs of the refrigerator until the body is perfectly horizontal. This will not only remove the noise, but also ensure that the doors close correctly.
Malfunctions of the electrical part and the starting relay
The electrical circuit of refrigerators Atlant is relatively simple, but it is the one that most often suffers from power surges in the network. If the refrigerator hums for several seconds, clicks and turns off without starting to cool, this is a classic symptom of a malfunction. Inside there is a posistor, which over time loses its properties or burns out. The winding of the motor itself may also burn out, but replacing the relay is the first place to start diagnosing. The cost of this part is low, and replacement takes 15-20 minutes. start relay.
The start relay is a small box attached to the compressor. Inside there is a posistor, which over time loses its properties or burns out. The winding of the motor itself may also burn out, but replacing the relay is the first place to start diagnosing. The cost of this part is low, and replacement takes 15-20 minutes.
In modern models with electronic control, control moduleis responsible for all processes. If error codes light up on the display (for example, temperature indicators are blinking), this is a direct signal of a failure in the “brains” of the device. Voltage surges can damage the board tracks or burn fuses.
Checking the integrity of the wiring is also important. Wires often fray at bends or near door hinges. A visual inspection of the harnesses can reveal oxidized contacts or breaks, which can easily be eliminated by soldering or replacing a section of cable.
Mechanical damage and problems with seals
The integrity of the thermal circuit is the key to effective operation. If sealing rubber band the door has lost its elasticity, become dirty or deformed, warm air constantly enters the chamber. This forces the compressor to work almost without stopping, which leads to its overheating and increased energy consumption.
You can check the tightness in a simple way: hold a sheet of paper with the door and try to pull it out. If the paper is removed without effort anywhere around the perimeter, the seal requires replacement or restoration. You can try to restore old rubber with a hot hairdryer, gently stretching it, but this is a temporary measure.
| Symptom | Possible cause | Difficulty of repair | Required tools |
|---|---|---|---|
| The refrigerator does not turn off | Wear of the seal, freon leakage | Medium / High | Hair dryer, soap solution, pressure gauge |
| Water on the floor | Drainage clogged, crack in pan | Low | Syringe, wire, glue |
| Loud knocking at start | Faulty start relay | Low | Screwdriver, new relay |
| Snow coat in the chamber | Faulty heating element or timer | Medium | Multimeter, screwdrivers |
Mechanical damage to the body itself, such as dents, can disrupt the geometry of the doors, causing them to no longer fit tightly. In rare cases, the internal circuit (evaporator) is damaged, which leads to an instant leak of freon and moisture entering the thermal insulation. Damage to the internal evaporator with a knife during defrosting is one of the most fatal mistakes, often making repairs economically unfeasible.
Prevention and extension of service life
To avoid costly repairs, you must follow simple operating rules. Regular defrosting (even for systems No Frost prevention does not hurt once a year) and washing the internal chambers will help keep the equipment clean. Do not place hot food in the refrigerator - this puts excess load on the compressor.
Keep the condenser grille at the back clean. Dust and pet hair adhering to the radiator impair heat transfer. The compressor is forced to work longer to compensate for poor heat dissipation. The back of the refrigerator should be vacuumed every 6-10 months.
⚠️ Attention: Do not attempt to open the sealed circuit or solder pipes yourself without the appropriate equipment and skills. This can lead to burns, fire or complete equipment failure. Working with freon requires a license.
It is also important to ensure good ventilation around the refrigerator. Do not move it close to the wall, leave a gap of at least 5-10 cm for air circulation. Following these recommendations will allow your Atlant to serve for many years without serious breakdowns.
Frequently asked questions questions (FAQ)
Why does the Atlant refrigerator work non-stop and does not turn off?
Most often this indicates a freon leak, a thermostat malfunction or loss of tightness of the door seal. The compressor tries to compensate for the lack of cold by operating in continuous mode. Diagnostics of the cooling system is required.
What to do if water appears inside the refrigerator?
First of all, check the drainage hole on the back wall. It could become clogged with food debris. Clean it with a special brush or soft wire. If the problem is not solved, the drain tray may have moved or the pan has cracked.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require defrosting when ice forms 3-5 mm thick (usually once every 3-6 months). Models with a system No Frost or a “crying” wall do not require forced defrosting, but preventive cleaning is recommended once a year.
Is it possible to replace the compressor on an Atlant refrigerator yourself?
Theoretically, it is possible, but this requires special equipment: a vacuum pump, a pressure gauge station, burner and freon supply. Without the skills of soldering and working with refrigerants, it is strictly not recommended to undertake this operation.
Why does the refrigerator hum loudly immediately after turning on?
A short-term hum when the compressor starts is normal. If the sound lasts a long time or is accompanied by a knock, check whether the tubes are touching the housing and inspect the start relay. It may need replacement.
