For any owner of household appliances who is faced with a breakdown, the first and most important question is the localization of the key component of the system. In refrigerators of the brand Atlant, which have been popular in the post-Soviet space for decades, the design often remains unchanged, but the nuances may vary depending on the series. Compressor is the heart of the unit, and understanding its location is critical for diagnostics or replacement.
Usually the search does not take much time, since the engineers of the Belarusian plant adhere to the classic layout. However, before you take any action, you need to be clearly aware of which model you are dealing with. Double-chamber and single-chamber versions may have differences in access to the technical compartment, although the basic principle remains the same for most modifications.
In this article we will look in detail at where to look for the motor, how to properly prepare for work and what tools you will need. Safety when working with electrical appliances and refrigerant comes first, so you should absolutely ignore the safety rules it is impossible. Let's look at the design of the rear panel of your refrigerator.
Classic motor arrangement in Atlant models
In the vast majority of cases, if you approach the refrigerator Atlant from the back, you will see a horizontally oriented black cylinder mounted on the frame at the bottom of the body. This is compressor, which is responsible for the circulation of refrigerant throughout the system. It is located asymmetrically, most often on the left side, when looking at the refrigerator from the back wall.
Next to it there is a capacitor grille, which can be black metal or aluminum, as well as a starter relay and a start-protective device. This entire structure is covered with a metal casing, which performs a protective function and reduces the noise level when the engine is running. It is accessible by unscrewing several screws or removing latches.
⚠️ Attention: Before attempting to remove the protective cover, make sure that the refrigerator has been unplugged for at least 30 minutes. Capacitors can retain charge, and the compressor itself, when hot, poses a risk of burns.
It is worth noting that in some two-compressor models Atlant (for example, the 40th or 45th series) there may be two such engines. They are installed next to each other or one above the other, each of which is responsible for its own cooling circuit - a freezer or a refrigerator. In such cases, the layout remains the same, there are simply more elements.
Design features of different series of refrigerators
Although the plant Atlant is trying to unify production, over the many years of production many modifications have been created, where the location of the components may vary slightly. In older models with manual defrosting, access to the motor was often simplified as much as possible. Modern units with a system No Frost or a “crying” wall may have a more complex rear panel configuration.
In models with a bottom-mounted freezer, the compressor group is usually hidden behind a decorative panel, which is bolted around the perimeter. In more budget or larger versions, the panel may be absent, and the motor is immediately visible, being covered only by a standard metal cap. Understanding the series of your refrigerator will help you find your way faster.
Let's look at the main differences in access:
- 🔹 KSh-200/250 series: Classic location on the bottom left, access through a removable metal casing with 4-6 screws.
- 🔹 Series with No Frost: The compressor often has increased power and can be moved closer to the center to balance the weight of the unit.
- 🔹 Built-in models: Here access is difficult due to the presence of an external box, and for repairs it is often necessary to move the entire refrigerator away from the niche.
It is important to consider that in two-compressor versions motor-compressors they may differ in size and performance. The main one, as a rule, is located to the left and has a larger volume, while the second one, serving the refrigeration compartment, can be more compact. When replacing parts, this plays a key role.
Instructions: how to access compressor
To carry out any work you will need a minimum set of tools. Typically this will include a Phillips screwdriver, a flathead screwdriver, and possibly an 8mm or 10mm ratchet if the housing is bolted on. The first step is always to completely disconnect the device from the network 220V.
Next, you should move the refrigerator away from the wall, providing free access to the back. If the floor is slippery, place thick cardboard or cloth under the feet to avoid scratching the surface when moving. Carefully remove the protective casing by unscrewing all visible fasteners.
☑️ Preparation for access
After removing the cover, you will have a view of the compressor group. You will see the motor cylinder itself, next to it there is an oval or round filter drier (copper cylinder), a starting relay (black or white plastic block on the side) and condenser tubes. Be careful not to yank copper pipes sharply, as they can become brittle over time.
⚠️ Attention: Never cut through or disconnect copper cooling system pipes without special equipment and skill. The release of freon into the atmosphere is harmful, and moisture getting inside the system will lead to expensive repairs.
If your goal is simply to check the integrity of the wires or visually inspect the relay for melting, these actions are sufficient. For deeper intervention, for example, replacing the compressor itself, you will need the skills of a roller and a vacuum pump.
Main elements of the compressor compartment
Having figured out where the compressor is located in the refrigerator Atlant, it is useful to know what this unit consists of. This will help you correctly explain the problem to the technician or select the right spare parts. The main element is a sealed housing, inside of which there is an electric motor and a piston group.
A start-protection relay is attached to the housing. It is this small block that often fails, causing clicks and failure to start the engine. Also located in close proximity is a condenser (if the model requires it for start-up) and a filter-drier that cleans the refrigerant from moisture and impurities.
The table below provides a description of the main components that you will see when you remove the casing:
| Element | Location | Function |
|---|---|---|
| Compressor | Center of frame, black cylinder | Pressure build-up and freon circulation |
| Start relay | On the side of the motor housing | Starting the engine and overload protection |
| Filter drier | Next to the motor, copper cylinder | Cleaning the refrigerant from moisture and garbage |
| Condenser grille | Rear wall, behind the motor | Cooling and condensation of gaseous freon |
Visual inspection of these elements often reveals obvious malfunctions: blackening of the relay, swelling of the capacitor or traces of oil under the compressor. The presence of oil stains under the compressor almost always indicates a violation of the tightness of the system or wear of the seals.
Diagnostics of faults by external signs
Understanding where the compressor is located helps in initial diagnosis. If the refrigerator Atlant stops freezing, but is humming, the problem may be a stuck piston group or faulty valves. If the motor is silent, but clicks are heard, most likely the problem is in the start relay or motor windings.
Pay attention to the temperature of the housing of the operating compressor. It should be hot, but not scalding. If the metal is so hot that it cannot be touched, this may indicate an interturn short circuit or problems with ventilation. In such cases, it is necessary to check the cleanliness of the condenser grille at the back.
Frequent symptoms of problems with the compressor group:
- 🔸 The motor turns on for a few seconds and turns off with a click.
- 🔸 The unit operates continuously without turning off, but the temperature in the chambers does not falls.
- 🔸 There is a smell of burning or scorched wiring in the area of the rear wall.
- 🔸 A metal knock or clanging sound is heard during operation.
Why can the compressor heat up more than usual?
This can be caused by a clogged capillary tube, loss of compression, or simply hot weather in the room where the refrigerator is located. The density of installation of furniture around the unit also affects.
Safety measures and operating rules
Working with refrigeration equipment requires compliance with strict rules. Even if you just want to know where the compressor is located in your Atlanta, remember the risks. Electric current and high pressure in the system are factors that do not forgive mistakes.
Never try to repair the sealed compressor housing yourself. Its opening is possible only in the factory using special welding equipment. All attempts to “revive” the motor by tapping or warming up can lead to an explosion or fire.
⚠️ Attention: If you smell gas or see sparking in the compressor area, immediately stop all work, turn off the machine in the panel and ventilate the room. Further repairs should only be carried out by a qualified specialist.
To extend the life of the compressor, it is recommended to regularly, at least once a year, clean the rear grille of dust and pet hair. This will improve heat transfer and reduce the load on the engine, which is especially important in the summer.
Frequently asked questions (FAQ)
Is it possible to replace the compressor in the Atlant refrigerator yourself?
Theoretically, this is possible if you have the skills to work with copper pipes, a vacuum pump and a set for refilling freon. However, this process is too complicated and risky for the average user. An error during soldering or refueling can permanently damage the equipment.
Why does the compressor vibrate and make a lot of noise?
Vibration can be caused by loosening of the fastening bolts on the frame, misalignment of the refrigerator on the floor, or wear of the internal shock absorbers of the motor. Also, the noise may be made by the fan (if the model has one), and not the compressor itself.
Where can I find the electrical connection diagram for my model?
The diagram is usually pasted on the inner wall of the refrigerator, on the door, or is in the technical data sheet. If the sticker is erased, the diagram can be found on the Internet using the exact model number indicated on the nameplate.
How long does an Atlant compressor last on average?
With proper operation and stable mains voltage, compressors Atlant last from 10 to 15 years or more. Frequent voltage fluctuations and overheating significantly reduce this period.
What to do if the compressor is cold, but does not start?
This is a sign of a malfunction of the starting relay, thermostat or control electronics. In this case, the motor itself is most likely working, but does not receive a command to start or cannot start due to a blockage.
