Independent dismantling of the compressor, which in everyday life is often called an engine, is one of the most difficult procedures in repairing household appliances Samsung. This operation requires not only theoretical knowledge about the structure of the refrigeration unit, but also the presence of specialized tools, as well as strict adherence to safety precautions. Compressor It is a sealed unit within which refrigerant circulates under high pressure, so any manipulation with it is fraught with risks.
Before Before starting disassembly, you need to clearly understand that simply replacing a part may not solve the problem if a high-quality diagnostics of the entire system is not carried out. Often, motor failure is a consequence of a clogged capillary tube or a malfunction of the starting relay, and not an internal defect of the unit itself. In this article, we will analyze in detail the process of removing the compressor, paying attention to the nuances of working with models Samsung of different years of manufacture.
It is important to understand that after removing the old engine, simply installing a new one and plugging the refrigerator into an outlet is not enough. The system requires professional refilling with freon vacuation, which cannot be done at home without expensive equipment. Therefore, this instruction is aimed at those who plan to replace the compressor for subsequent transfer of equipment to a service center or have the necessary set of tools to complete the work independently.
Preparation of the workplace and the necessary tools
High-quality preparation for work takes up to 30% of the total time spent on repairs. To safely and effectively dismantle the refrigerator compressor Samsung you will need to organize a spacious work area with good lighting. There should be no moisture on the floor, and it is better to cover the surface with thick cardboard or a rubber mat to prevent slipping and damage to parts when falling.
The basic set of tools should include not only standard screwdrivers and pliers, but also specific devices. It is critical to have a pipe cutter on hand for copper tubing, as cutting it with wire cutters can deform the ducts and make further installation difficult. A pressure gauge manifold is also required to bleed off the residual refrigerant pressure before starting work.
- 🔧 A set of screwdrivers (phillips and slotted of different sizes) for removing protective panels.
- 🔪 Pipe cutter for copper pipes with a diameter of 1/4 and 3/8 inches.
- 🔥 Blowtorch or solder torch for soldering pipelines (if required).
- 🧤 Dielectric gloves and safety glasses for eye and hand safety.
- 🔨 Hammer and pliers for carefully bending metal elements.
Special attention should be paid to power tools. If the compressor is stuck to the frame or the mounting bolts are rusty, you may need grinder or a Dremel with a cutting wheel to carefully cut off the old fasteners. However, they should be used with extreme caution so as not to damage the condenser or other elements of the refrigeration circuit located in the immediate vicinity.
Safety measures and preparation of the refrigerator
⚠️ Attention: Before starting any work, it is strictly forbidden to connect the refrigerator to the electrical network. Make sure that the power cord is unplugged and that the capacitors (if present in the control circuit) are discharged. Working with live electrical components is deadly.
The first stage of preparation is to completely defrost the unit. Even if the refrigerator system is No Frost, condensation or ice may remain inside in hard-to-reach places. Leave appliances unplugged for at least 12 to 24 hours with doors open. This will not only protect you from a short circuit, but will also prevent water from entering the electrical contacts of the compressor.
After defrosting, it is necessary to provide access to the rear of the device. Move the refrigerator at least one meter away from the wall so that you can freely walk around it from all sides. Remove the rear metal cover covering the compressor compartment. It is usually attached to four screws, which can be hidden under decorative plugs.
Bleeding the refrigerant is a critical point. Modern models Samsung use gas R600a (isobutane), which is flammable. Puncture of a capillary tube in an enclosed area may result in the formation of an explosive gas concentration. It is better to carry out the procedure in a well-ventilated area or outdoors, using a piercing valve.
Removing protective elements and access to the compressor
After removing the main rear cover, you will have access to the motor-compressor, capacitor grid and start relay. In some models Samsung the compressor can be additionally closed with a plastic casing or soundproofing box. These elements must be carefully dismantled by snapping off the plastic clips or unscrewing the fastening screws.
The next step is to disconnect the electrical part. Find the start relay and thermostat, which are placed directly on the contacts of the compressor. Carefully remove the plastic relay box, after photographing the wiring diagram. This will help to avoid errors during assembly, since the color marking of the wires in different batches of equipment may differ.
To disconnect the wires, use pliers or a special puller, avoiding jerks that can damage the insulation or tear off the contacts. After turning off the electrics, inspect the copper pipes leading to the compressor. Usually there are two of them: one thin (discharge) and one thicker (suction). They can be soldered or connected through threaded fittings in newer models.
Mounting nuances in different models
In older Samsung models, compressors were often mounted on bolts with rubber washers, which became dull over time. Modern units use a spring suspension system inside the casing, which requires special care during removal so as not to damage the pipelines.
Disconnecting the pipelines and removing the compressor
This is the most critical stage, requiring maximum concentration. If the tubes are soldered, they must be cut with a pipe cutter at a distance of 10–15 cm from the soldering point. Do not use a hacksaw or wire cutters in the immediate vicinity of the compressor housing, as metal shavings that get inside the system can completely damage the new unit.
When working with a pipe cutter, it is important not to clamp the tool too tightly so as not to flatten the tube. Make a small cut, then carefully break the tube and remove the remaining bridge. If you plan to reuse an old compressor (for example, for a compressor pit), you need to unsolder the tubes in compliance with all precautions, having first drained the oil.
The compressor itself is usually secured to the refrigerator frame through four rubber shock-absorbing bushings and metal washers. Models Samsung often use bolts screwed in from the bottom of the frame, or studs with nuts on top. To unscrew them, you may need a wrench with an extended head or a ratchet.
| Type of connection | Tool | Dismantling features | Risks |
|---|---|---|---|
| Soldering (solder) | Pipe cutter, torch | Requires careful cutting without chips | Scale getting into the system |
| Threaded fitting | Adjustable wrench | It is necessary to hold the mating part | Thread breakage due to rust |
| Bolt fastening | Spanner wrench | Often access from below is required | Broken pin due to corrosion |
| Spring suspension | Pliers | High spring tension | Hand injury, compressor misalignment |
After disconnecting all communications, the compressor is still attached to the frame. Holding the unit body with one hand (it is quite heavy, the weight can reach 10 kg), carefully unscrew the mounting bolts. If the bolts do not give way, do not apply excessive force so as not to tear off the edges - it is better to treat them with penetrating lubricant WD-40 and wait 10-15 minutes.
Typical errors during dismantling and their consequences
One of the most common mistakes is neglecting cleanliness when working with copper tubes. If moisture, dust or metal shavings get inside the system, it leads to the formation of acids that destroy the windings of the new motor and clog the capillary tube. This is guaranteed to lead to repeated failure of the refrigerator in a short time.
Another common mistake is improper storage of the removed compressor. If you plan to use the old unit or temporarily leave the new one without the pipes attached, the openings must be sealed. The entry of moist air inside causes oxidation and loss of oil properties, which is critical for the durability of the mechanism.
⚠️ Attention: Never turn the compressor upside down or place it on its side at an angle of more than 40 degrees without prior preparation. Oil from the crankcase can enter the circulation circuit, which will cause water hammer at the first start and destruction of the valve group.
Also, technicians often forget to replace the filter drier when replacing the compressor. This element is disposable and when the system is opened, it instantly absorbs moisture from the air. Installing an old filter will negate all repair efforts, since it will not be able to perform its function of removing moisture and acids from freon.
☑️ Checklist before removal
Disposal of old equipment and preparation for installation
The removed compressor is scrap of ferrous and non-ferrous metals, but also contains residues of technical oil, which cannot be poured into the sewer or onto the ground. The oil may contain breakdown products of freon and acids that pollute the environment. It is recommended to return the old unit to a specialized electronics collection point.
If you are installing a new compressor, make sure that it fully matches the model of your refrigerator Samsung. The parameters must match not only in overall dimensions and seats, but also in refrigeration capacity, type of refrigerant and the required type of oil (mineral or synthetic POE).
Before soldering the tubes of a new compressor, it is necessary to purge the system with nitrogen to remove oxides and foreign inclusions. Soldering should be carried out in a nitrogen environment or immediately after soldering, purge the circuit to burn out the remaining oxygen. This will prevent the formation of carbon deposits inside the system in the future.
FAQ: Frequently asked questions
Is it possible? remove the compressor without bleeding the freon?
Theoretically, you can cut through the pipes, but this is extremely dangerous. Gas under pressure will escape, taking with it drops of oil, and can ignite from a spark from the tool. In addition, a sudden release of pressure can damage the internal structure of the compressor. Always bleed gas through a puncture in a safe place. data-i="138">Why does the new compressor heat up more than the old one?
Why does the new compressor get hotter than the old one?
This may be due to several factors: insufficient amount of refrigerant, the presence of air in the system, a malfunction of the condenser, or a mismatch in the power of the new unit. Also, the temperature depends on the load on the refrigerator. If only the body is heated, but there is cold, this may be normal for some operating modes. data-i="140">Is it necessary to change the oil in a new compressor?
Do I need to change the oil in a new compressor?
No, modern compressors are supplied already filled with the required amount of factory-quality oil. Adding or changing oil in a new unit is strictly prohibited, as this will upset the balance of the system and can lead to mixing of incompatible types of oils.
How to understand that the compressor "buzzing" but does not start?
This is a classic sign of a jammed mechanical part of the motor or a malfunction of the starting relay. If, when turning on, you hear a humming sound that lasts a few seconds, and then a click of the relay, most likely the engine is trying to start, but cannot turn the shaft. The relay or the compressor itself needs to be replaced.
