Sudden stoppage of the refrigerator Pozis often becomes an unpleasant surprise, especially when food in the chamber begins to deteriorate. In most cases, if the compressor hums but does not start, or characteristic clicks are heard but there is no cold, the problem lies in the start-up relay. This small but critical element is responsible for starting the engine and protecting it from overloads. Finding and buying a relay for a Pozis refrigerator is a solvable task, but requires attention to detail, since the market offers many analogues.
Finding a suitable spare part can take time if you do not know the exact model of your unit or part number. The Russian brand Pozis (Pozis Plant CJSC) uses various types of compressors in its refrigerators, most often domestically produced, but imported units can also be found in new models. The configuration and electrical characteristics of the relay you need depends on the type of compressor. An error in selection can lead to repeated breakdown or failure of the engine itself.
In this article we will look in detail where to look for original and compatible components, how to decipher the markings and what to look for when purchasing so that your refrigerator works properly again.
Types of start-up protection relays in Pozis technology
Understanding the structure of your equipment is the first step to successful repair. Refrigerators Pozis are equipped mainly with two types of compressors: classic linear and more modern inverter (although the latter are less common in budget series). For linear motors, electromagnetic or induction starting relays are used, often combined with a thermal release in one housing. Induction relay closes the starting winding at the moment of starting, and then opens the circuit when the rotor picks up speed.
Important distinguish relays by mounting method and housing shape. In older models of Pozis refrigerators, such as the Sviyaga or Mirseries, RT and RTP type relays were often used, which were attached directly to the compressor casing. Modern models may have more compact plastic housings with a detachable design. It is critically important to know: relays from Danfoss/Secop compressors are not always suitable for domestic motors without adapters or modification of contacts, despite the external similarity.
⚠️ Attention: Before purchasing, be sure to remove the old relay and compare its appearance, number of contacts and connection diagram with photographs in the online store. A visual discrepancy is a sure sign that the part will not fit into place.
Where to look for original spare parts: official channels
The most reliable, but not always the fastest way to purchase a relay is to contact the authorized service centers of the manufacturer. The company Pozis has a wide network of representative offices throughout Russia. Purchasing from an official guarantees that you will receive a part that has passed quality control and fully complies with the technical specifications of your refrigerator model.
Often on the websites of service centers or in their warehouses you can find original components even for discontinued models. However, it is worth considering logistics: if there is no representative office in your city, the part will have to be ordered by delivery, which will increase the downtime of the equipment. This option may not be suitable for urgent repairs, but for those looking for a durable solution, this is the best way.
When contacting the service center, prepare the full range of your device. Usually the information sticker is located inside the refrigerator compartment on the side wall or on the back panel. You will need not just the name "Pozis", but a full index, for example RF-33NF-2 or C-241. This will allow a warehouse employee to instantly identify the required modification of the relay.
Online spare parts stores and marketplaces
With the development of e-commerce, buying a relay for a Pozis refrigerator has become much easier. Large specialized online stores of spare parts for household appliances offer catalogs where you can select a part based on the model of the refrigerator or the part number. Here you often find both originals and high-quality analogs, which are cheaper, but not inferior in reliability.
Marketplaces also offer a wide range, but here you need to be extremely careful. Different sellers may post photos of similar, but not identical relays. Carefully study customer reviews, especially those where there is a photo of the purchased product “live”. Look for sellers with an "Original" or "Verified Supplier" rating.
When ordering online, pay attention to the following parameters:
- 📦 Manufacturer's article number: check the numbers on the body of your old relay with the product description.
- 🔌 Contact type: the number of pins and their location should match 100%.
- 🏭 Country of production: for Pozis refrigerators is preferable to Russian-made relays (for example, "Orsky Zavod" or "Don") or proven European brands.
Why an analogue can cost 3 times cheaper than the original?
Cheap analogues are often made using thinner metal in the contact group and lower-quality plastic housing. This can lead to the fact that if the compressor vibrates strongly, the contacts will begin to spark or the housing will melt after several months of operation. Savings of 200 rubles can result in repeated repairs in six months.
Compatibility table and popular articles
To simplify the search, we have compiled a table of correspondence between popular models of Pozis refrigerators and the types of relays used in them. Remember that the plant could make changes to the design in different years of production, so a visual check is required.
| Pozis refrigerator series | Compressor type | Relay type (example) | Article / Analogue |
|---|---|---|---|
| Pozis Sviyaga (old models) | Linear (Atlant/Don) | Starting RTK-1 | RTK-1-3, RTK-1-4 |
| Pozis Mir (XII, XIII series) | Linear | Start-protective RTP | RTP-1, RTP-2, RTP-3 |
| Pozis RK-139, RK-149 | Linear (Don) | Set (Relay + Thermo) | PC-1, PC-2 (analog RT) |
| Pozis Frio (modern) | Linear (Embraco/Danfoss) | Starter 117N | 117N0011, 117N0071 |
The table shows the most common options. If your model is not listed, look for the markings on the relay itself. It is usually applied with indelible paint on the side or top. Codes like 17.006.00 or R-6 will help you find an exact replacement in suppliers' catalogs.
Instructions for replacing the relay yourself
If you decide not to contact a technician and carry out the replacement yourself, strictly follow safety precautions. Working with electrical appliances requires turning off the power. Before starting work, make sure that the refrigerator is unplugged from the outlet.
⚠️ Attention: Do not touch the internal components of the compressor immediately after operation. The engine casing may be hot. Allow the equipment to cool for at least 30-40 minutes before dismantling.
☑️ Checklist before starting replacement
The replacement process is as follows. First, remove the back cover of the refrigerator to gain access to the compressor at the bottom of the cabinet. You will see a black cylindrical or pear-shaped tank - this is the motor. The required relay is attached to its end or side. Carefully disconnect the wire connectors, first remembering or photographing their location. Then remove the old relay by simply pulling it off the compressor contacts.
Install the new relay, pushing it tightly onto the motor terminals. It should fit tightly, without backlash. Connect the wires according to the diagram or photograph you made earlier. Make sure that the wires do not touch hot parts of the compressor or moving parts (if there is a fan). After assembly, turn on the refrigerator and listen: the startup should be smooth, without buzzing or clicking.
Common mistakes when purchasing and installing
One of the common mistakes is ignoring the condition thermal relay (thermal protection). Often in older style relays the starting and protective parts are combined, but in some designs they are separated. If you change only the starting part, but the thermal part remains old and worn out, the compressor may burn out at the first overload. Always check the condition of the entire contact group.
Another mistake is installing the relay “at random”, without checking the tightness of the contacts. Poor contact leads to heating, oxidation and eventual burning of the terminals. Use pliers to lightly tighten the connections, but without fanaticism, so as not to break the plastic elements.
- 🚫 Ignoring the cause of the breakdown: If the relay burns out, this is often the result of a power surge or problems with the compressor itself. Simply replacing the relay may not solve the root of the problem.
- 🚫 Purchasing used spare parts: The relay is a consumable item with a limited resource for on/off cycles. Buying it secondhand or at a showdown is a lottery with a low chance of success.
- 🚫 Incorrect orientation: Some relays (especially induction) are sensitive to their position relative to the ground. Install them as they were installed at the factory (usually the “UP” marking points up).
Can an old relay be repaired?
Theoretically, you can clean the contacts or replace a burnt out coil, but in practice this is a temporary measure. The cost of a new relay is low, and the reliability of the restored device is questionable. Relay repair is justified only if it is completely impossible to find a replacement in remote regions.
The cost of repairs and the feasibility of replacement
The price of a start-up protection relay for a Pozis refrigerator varies depending on the type and supplier. Simple domestic models (RT, RTP) are inexpensive, usually from 300 to 800 rubles. More complex imported analogues or kits can cost from 1000 to 2500 rubles. If you change the relay yourself, the costs will be minimal.
If you involve a specialist, the cost of the work will be added to the cost of the spare part. On average, a technician’s visit and replacement of the relay will cost 1,500–3,000 rubles, depending on the region. Comparing this amount with the cost of a new refrigerator, replacing the relay looks cost-effective, extending the life of the equipment by 5-10 years.
What to do if the new relay does not start the compressor?
If after replacing the relay the refrigerator buzzes but does not start, the following reasons are possible: the compressor itself is faulty (interturn short circuit or wedge), There is a wiring problem, or the wrong relay is installed. It is also worth checking the capacitor (if there is one in the circuit). In this case, it is better to call a professional diagnostician.
Is it possible to use a relay from another brand, for example, Atlant?
Pozis refrigerators are often equipped with Atlant compressors, so relays from Atlant are often ideal. However, it is important that the electrical characteristics (cut-off current) and the mounting geometry coincide. Universal relays require careful selection according to cross-compatibility tables.
How often do you need to change a prevention relay?
The start-up protection relay does not have a scheduled replacement period “for prevention”. It is changed only when symptoms of a malfunction appear: the refrigerator does not turn on, clicks, or the compressor runs in short cycles. The service life of a high-quality relay is thousands of cycles, which corresponds to 10-15 years of operation.
In conclusion, searching for a relay for a Pozis refrigerator is a process that requires precision. Knowing the model of your unit and the part number, you can easily find a replacement in specialized stores or online. The main thing is not to skimp on the quality of the spare part, since the “heart” of your refrigerator depends on this small element.
