When your reliable refrigerator Atlant stops freezing or, conversely, turns food into ice blocks, the first suspicious element is often the thermostat. This small device controls the cycles of turning the compressor on and off, maintaining the set temperature. Finding an original or compatible part becomes a critical stage in restoring the functionality of household appliances.
Owners often wonder where exactly to purchase a quality one thermostatso as not to overpay and be confident in the durability of the repair. The spare parts market today is overflowing with offers from official services, online stores and private sellers on marketplaces. It is important not only to find the part, but also to make sure that its parameters correspond to your refrigerator model.
In this article we will analyze all the nuances of searching, checking and installing a thermostat so that you can make an informed decision on your own. Understanding the markings and design features will help you avoid errors when ordering.
⚠️ Attention: The parameters of thermostats may vary slightly in different batches of equipment. Before purchasing, always check the markings on the body of your old part with the characteristics of the new one.
Types of thermostats for Atlant equipment
Belarusian-made refrigerators are equipped with different types of temperature sensors depending on the year of manufacture and model series. The most common option is mechanical thermostat with a capillary tube. Inside such a device there is a bellows filled with a temperature-sensitive gas or liquid, which expands or contracts, opening or closing electrical contacts. Mechanical thermostat More modern models, especially those with a system or electronic control, can be equipped with electronic resistance sensors. However, classic two-chamber refrigerators most often use mechanics. The differences lie in the length of the capillary tube, the type of fastening and the temperature range of operation.

However, classic two-chamber refrigerators most often use mechanics. The differences lie in the length of the capillary tube, the type of fastening and the temperature range of operation.
When choosing a new part, it is important to pay attention to the presence of a third contact. It is designed to connect an overflow indicator or a signal light that lights up when the temperature in the chamber rises. If your model does not have such a function, this contact may remain free, but the design of the case itself should allow installation.
How to determine the model and marking of a part
Before you go looking for a place to buy a thermostat for a refrigerator Atlant, you need to accurately identify the required spare part. The most reliable way is to dismantle the old regulator and study the markings on it. Typically, the marking contains information about the manufacturer (for example, TAM, K59, RANCO) and a digital code.
The key parameter is the length of the capillary tube. Standard values range from 0.75 meters to 2.5 meters or more. Installing a thermostat with a shorter tube is impossible without losing the seal, and a tube that is too long can be carefully placed in the free space of the evaporator, taking precautions.
It is also worth considering the type of control rod. In some models, it may have a specific notch or length necessary for a tight fit of the regulator handle. A discrepancy in this parameter will result in you not being able to turn the temperature setting knob normally.
Where to look for original spare parts and analogues
Finding a reliable supplier is a balance between price, delivery speed and quality guarantee. There are several main channels through which you can purchase the necessary thermostat.
- 🏢 Official service centers: Here you will receive a guaranteed original part, but the price may be higher than the market price, and the waiting period may be long if the spare parts are not available in stock.
- 🛒 Specialized online spare parts stores: They offer a wide range of analogues (China, Türkiye, Europe) with detailed descriptions and photos. They often provide their own guarantee for the product.
- 📦 Large marketplaces: Easy search and fast delivery, but there is a high risk of running into an unscrupulous seller. Carefully study the reviews and ratings of the store before purchasing.
When purchasing on third-party resources, always check the possibility of returning the product. A thermostat is a technically complex product, and if it does not fit in size or parameters, you should be able to replace it.
⚠️ Attention: Avoid purchasing thermostats without packaging or with a damaged capillary tube. Even a microscopic crack will lead to leakage of the working substance and malfunction of the part.
Comparison of manufacturers and price range
The market for spare parts for refrigerators Atlant is dominated by several major brands that produce compatible thermostats. Understanding the differences between them will help you make the right choice. Most often there are products under the brands TAM, Ranco and Orbital.
European brands, as a rule, are distinguished by more stable response characteristics and durability of contacts. Chinese analogues may cost less, but their service life is sometimes lower, which leads to more frequent breakdowns in the future.
| Brand / Type | Country of production | Average price (RUB) | Features |
|---|---|---|---|
| TAM (Series 112, 133) | China / Poland | 800 - 1200 | Popular analogue, wide choice of tube lengths |
| Ranco (K59, K50) | Italy / China | 1300 - 1800 | High reliability, often comes in the original |
| Orbital | China | 600 - 900 | Budget option, requires careful checking |
| Atlant (Original) | Belarus | 1500 - 2200 | Full compliance with factory specifications |
Price may also depend on the length of the capillary tube: the longer it is, the more expensive the product. You should not chase the maximum cheapness, since replacing a thermostat requires time and effort, and it will be a shame to repeat the procedure in six months.
Why are imported thermostats often better?
Imported manufacturers use higher quality alloys for contacts and more inert gases in the bellows, which ensures stable operation over a wide temperature range and extends the service life compressor service.
Instructions for inspection before purchase and installation
Before finalizing the order or starting installation, it is recommended to conduct a visual inspection of the part. Make sure that the capillary tube has no kinks, dents or signs of oxidation. The metal flask at the end must be sealed.
If possible, check the functionality of the contacts using a multimeter in dial mode. At room temperature, the contacts are usually closed (a squeak is heard). If you place the sensitive flask in the freezer or cover it with ice, after a while a click should be heard and the circuit will open.
☑️ Checking the thermostat before installation
When installing a new part, it is important to secure it correctly thermal cylinder. It should fit tightly to the evaporator in a special socket or be pressed with a bar. Poor contact will lead to incorrect temperature reading and frequent starts of the compressor.
Frequent errors in selection and installation
One of the most common mistakes is ignoring the temperature range. Installing a thermostat designed for lower temperatures will cause the refrigerator to freeze less than it should. Conversely, a sensor with a “warm” range will cause the compressor to work almost non-stop.
Also, craftsmen often forget about the tightness of the tube outlet. The place where the capillary tube comes out of the refrigerator body must be carefully sealed with a special compound. Otherwise, warm air will penetrate inside, causing ice formation and increased energy consumption.
⚠️ Attention: Never bend the capillary tube at an acute angle or allow it to twist. This will lead to irreversible damage to the sensor.
Another mistake is using inappropriate tools for dismantling. The plastic latches of the thermostat housing are fragile, and rough impact can break the body of the new part even before use.
Questions and answers (FAQ)
Is it possible to install a thermostat with a longer tube than it was originally?
Yes, you can. The excess capillary tube must be carefully rolled into a ring (with a radius of at least 4-5 cm) and placed in the free space behind the panel or inside the chamber, avoiding contact with the moving parts of the fan (if any). The main thing is not to damage the tube.
What is the difference between thermostats K59 and K50?
The main difference is the temperature range of operation. K59 usually used in two-chamber refrigerators (for the refrigerator compartment), and K50 - in single-chamber ones or for freezer compartments. Installing the wrong type will lead to a violation of the temperature regime.
Why does the new thermostat click, but the compressor does not turn on?
This may indicate a malfunction of the compressor itself, the start relay, or a problem with the wiring. The thermostat only gives a signal to turn on. If there is a click, it means that the control circuit is working, and you need to look for the cause in the power part.
How long does it take to deliver the thermostat to the regions?
The timing depends on the selected seller and logistics company. When ordering from local parts stores, the lead time is 1-3 days. Delivery from large marketplaces or from central warehouses can take from 3 to 7 days.
