How to open the lid on the compressor of the Atlant refrigerator

Situation when access to motor-compressor of the refrigeration unit, occurs quite often during maintenance or troubleshooting. The owner of the equipment Atlant may be faced with the need to replace the starting relay, check the integrity of the windings, or simply clean the surface from dust and dirt. Despite the fact that modern models are designed with maintainability in mind, the process of dismantling the protective casing has its own specific features, ignoring which can lead to damage to copper tubes or electrical contacts.

Before taking active steps, it is necessary to clearly understand that the compressor is the heart of the refrigeration system and operates under high pressure. Any carelessness when removing the cover may cause depressurization of the circuit or short circuit. In this article, we will analyze in detail the algorithm of actions for various series of household appliances Atlant, paying special attention to the nuances of fastening and precautions that will ensure the safety of the master and the safety of the equipment.

To successfully complete the task, you will need a minimum set of tools that can be found in the arsenal of any home craftsman. A flathead and Phillips screwdriver, as well as pliers, are usually sufficient. In some cases, if the housing is very dirty or rusty, a penetrating lubricant may be needed. The main thing is to act consistently and without the use of excessive physical force, which often causes breakage of plastic latches or deformation of metal elements.

Preparatory stages and electrical safety measures

The first and most critical step is to completely de-energize the refrigerator. Electrical safety When working with household appliances, it comes first location, since the compressor unit operates from a 220 volt network. It is not enough to simply turn off the button on the case, if there is one; you must physically remove the plug from the socket. This will eliminate the risk of electric shock if you accidentally touch the terminal box or damaged wire insulation during dismantling.

After turning off the power, move the refrigerator away from the wall, providing free access to its back. It is recommended to carry out work in good lighting in order to visually monitor the condition of the pipes and electrical connections. If the unit has been in operation recently, the compressor may be hot, so it is worth allowing it to cool for 15-20 minutes before starting any manipulations. This will also reduce the temperature of the refrigerant in the system, which minimizes the risks of accidental damage to the tubes.

⚠️ Attention: It is strictly forbidden to carry out any work on disassembling the compressor unit while the power cord is connected to the mains, even if the refrigerator is turned off with the button. Residual voltage in the start relay capacitors can be dangerous.

Prepare the work area by covering the floor with cardboard or rags to prevent dropped small parts such as screws or springs from becoming lost and scratching the surface. Prepare a container in advance for storing fasteners. Models Atlant typically use different types of screws, and it is not advisable to mix them up during assembly. Also make sure that you have a dry rag on hand to remove dust that has inevitably accumulated in the niche of the unit.

Necessary tools and consumables

The quality and speed of the work directly depend on the correctness of the selected tools. To dismantle the compressor casing of refrigerators Atlant no specialized expensive equipment is required, however, the use of unsuitable objects can tear off the splines on the screws or damage the plastic. The main tool is a set of screwdrivers with different blades.

Depending on the year of manufacture of the model and the specific series, fasteners may differ. In older models, screws for a slotted screwdriver are often found, while in new ones a cross profile prevails. PH2. Sometimes the screws may be varnished or show signs of corrosion, making them difficult to remove. In such cases, pre-treatment with a penetrating lubricant helps, which will dissolve the oxides and facilitate the thread.

In addition to the main tool, it is recommended to have the following accessories on hand:

• 🔧 A set of screwdrivers (phillips and slotted in different sizes) for working with various fasteners.
• 🔦 Powerful a flashlight or headlamp to illuminate hard-to-reach places in the rear niche.
• 🧤 Protective gloves with a rubberized coating to protect your hands from sharp metal edges.
• 🧹 A soft brush for preliminary cleaning the surface of the casing from dust before removal.

If you If you plan not only to remove the cover, but also to diagnose or replace components, it makes sense to prepare a multimeter to test the circuits. You may also need some electrical tape or heat shrink in case you need to temporarily insulate the wires. For models with a lower roll-out cassette or a specific mount, you may need a ratchet wrench with a set of heads, although for most household Atlantov hand tools are sufficient.

The algorithm for removing the protective casing

The process of dismantling the compressor cover on refrigerators Atlant is standardized, but requires attention to the fastening details. The main difference is in the location of the fixing elements: in some models the screws are located around the perimeter of the metal cap, in others - on the plastic frame enclosing the unit. In most cases, it is necessary to turn the refrigerator over or tilt it strongly to gain access to the bottom.

Find the fasteners holding the casing. Usually their number varies from two to four pieces. Some modifications Atlant use a latch system in combination with screws. If the screws are unscrewed and the cover cannot be removed, do not use force - there may be unnoticed fixing elements or wires getting in the way. Carefully pull the casing down or to the side (depending on the design), releasing it from the grooves.

⚠️ Attention: When removing the metal casing, watch out for its edges - they may be sharp. In addition, a sudden movement can lead to a jerk of the copper tubes connected to the compressor, which can lead to their breakage or depressurization of the system.

After physically separating the casing from the compressor body, inspect the inside. Often, a starting relay and a thermostat are mounted on the inside of the metal cap. It is not necessary to remove them immediately if the purpose is only cleaning or visual inspection, but to access the compressor contacts themselves, you will need to disconnect the wire block. This must be done while holding the relay with the second hand so as not to damage the fragile contacts.

Design features of different Atlant series

The equipment of the Minsk plant has been produced for several decades, and during this time the design of the compressor compartment has undergone changes. Early models were often equipped with more massive casings with screw fastening around the entire perimeter. Modern lines, such as the XM or MXMseries, may have a simplified access system, where the cover is removed after unscrewing just a couple of screws or releasing the plastic clips.

It is important to consider the type of compressor installed in your refrigerator. The units can be equipped with motors from different manufacturers (for example Atlant, Secop, Embraco), and the shape of the protective casing depends on the dimensions and configuration of the motor. In two-compressor models, access to each of them is carried out individually, and the design of their protection may differ.

Below is a table systematizing the mounting features depending on the series:

For built-in models, access is often complicated by the fact that the refrigerator is pressed tightly against the walls niches. In such cases, it may be necessary to partially remove the decorative panels or plinth in order to obtain sufficient viewing angle and maneuverability to remove the cover. Always evaluate the space around the unit before starting work.

Diagnostics and maintenance after removing the cover

By opening access to the compressor, you have the opportunity to visually diagnose the condition of the unit. First of all, inspect the surface of the motor for traces of oil, which may indicate a leak in the seals or microcracks in the housing. Also check the condition of the copper tubes: they should not have creases, deep corrosion or traces of soldering, indicating previous repairs.

Pay attention to the starting relay and capacitor. If carbon deposits or oxidation are visible on the contacts, they should be carefully cleaned. A humming or clicking sound when trying to start (after being plugged in) often indicates a malfunction of these elements, and not the compressor itself. Replacing a relay is a simple procedure, but requires precise selection of an analogue according to the marking.

Dust removal is an important part of maintenance. A condenser clogged with dust (black grille at the back) and the compressor itself give off heat worse, which causes the motor to work with overload. Use a soft brush or vacuum cleaner on low power to remove dirt. Ventilation The engine compartment must be clear for the refrigerator to operate efficiently.

What to do if the compressor is cold but does not start?

If when turned on, the refrigerator is silent, but there is light inside, and the compressor is cold and does not make sounds, most likely the problem is in the control circuit (thermostat, module) or a broken winding. If you hear a hum and clicks, the motor is most likely jammed or the start relay is faulty.

Typical errors and precautions

When performing work on their own, beginners often make mistakes that can lead to serious consequences. One common problem is loss of system tightness. The copper tubes leading to the compressor are very thin-walled, and careless movement with a tool or the casing itself can puncture them. Repair in this case will require calling a technician with a vacuum pump and refilling with freon.

Another common mistake is incorrect installation of the start relay after removing the casing. The relay must be placed on the compressor contacts strictly in a certain position, which is usually indicated by an arrow or an inscription UP (top). If you turn the relay over, the compressor will not start or the winding will burn out. Always check the orientation of the part before fixing.

⚠️ Warning: Never try to straighten dented copper tubing with your hands or pliers - they will burst instantly. If the tube is deformed, it is better to leave it as is, if the passage of the refrigerant is not impaired, than to risk depressurization.

It is also worth mentioning the risk of damage to the wire insulation. It is often hot in the engine compartment, and the insulation becomes dull over time. Rough tugging of the wires when removing the casing can lead to cracks and subsequent short circuits. Carry out all manipulations with the electrical part only with the power turned off and with maximum care.

Completing work and checking functionality

After all the necessary manipulations inside the casing have been completed, be it cleaning, replacing a relay or diagnostics, you can begin assembly. Reinstall the protective cap, making sure it does not put pressure on the tubes or wires. Tighten all mounting screws securely, but do not overtighten them to avoid stripping the threads in soft metal or plastic.

Before final installation of the refrigerator in its original location, it is recommended to perform a test run. Plug in the unit and listen to the compressor operate. It should start in a few seconds (or immediately, depending on the model) and run smoothly, without vibrations or extraneous knocks. The casing should not rattle from engine vibration; if this happens, check the tightness of the fit and the presence of all screws.

After making sure that it is working properly, move the refrigerator away from the wall at the normal distance (at least 5-10 cm for air circulation) and leave it working. During the first hour, check whether traces of oil or frost appear on the compressor tubes in the wrong places. If all parameters are normal, the work can be considered successfully completed.

Is it necessary to lubricate the rubbing parts of the compressor with oil?

No, the compressor is a sealed unit, and there is already a special oil inside it. It is strictly forbidden to add oil from the outside or open the housing. You can only lubricate the moving parts of external mechanisms, if any, but the motor itself does not need it.

Is it possible to operate a refrigerator without a metal casing?

For a short time - yes, for diagnostics. But constant work without a casing is undesirable: it serves as protection against dust, moisture and accidental touches, and also participates in the correct distribution of air flows to cool the motor.

What to do if the fastening screws are rusty and do not rotate?

Do not use excessive force immediately. Treat the screw heads with a penetrating lubricant (such as WD-40) and leave for 10-15 minutes. Then try to carefully rip them off with a screwdriver, pressing the tip tightly. If the cap comes off, use pliers or drill out the remains.

Why did the refrigerator begin to make more noise after installing the cover?

Most likely, the casing is installed incorrectly and vibrates against the compressor body or tube. Also check if the tubes are pinched. Sometimes rattling is caused by a loose screw or a small part getting inside.

How often do you need to remove the cover for prevention?

There is no need to specially remove the compressor cover for prevention. It is enough to vacuum the rear grille of the condenser 1-2 times a year. You should only go inside if there are malfunctions or obvious signs of oil contamination.
