Refrigerators Biryusa are one of the most popular in Russia due to their reliability and affordable price. However, even with proven models, key components fail over time, and the thermostat (or thermostat) is no exception. This small device is responsible for maintaining the set temperature in the chambers, and its breakdown leads to serious problems: from constant operation of the compressor to the complete absence of cold.
In this article we will analyze which thermostat is suitable for Biryusa refrigerators different series, how to select it correctly according to the model, and also give step-by-step instructions for replacement. You will learn what signs indicate a malfunction of the thermostat, how to check its performance and where to buy original spare parts. Let us separately dwell on the nuances of choosing analogues - this will help save money without losing quality.
The material will be useful for both owners of old models Biryusa-3, Biryusa-6, and modern refrigerators of the series KShD or BS. All recommendations are based on the official data of the manufacturer and the experience of repairmen of household appliances.
What thermostats are installed on Biryusa refrigerators
The manufacturer equips refrigerators Biryusa thermoregulators of several types, depending on the model and year of manufacture. Most devices are equipped with Russian-made thermostats brand TAM (Termoavtomatika, Miass) or imported analogues from Danfoss (now - Secop).
Basic series of thermostats for Biryusa:
- 🔹 TAM-112 —the most common option for single-chamber models (Biryusa-3, Biryusa-6Operates in the range from -24°C to +6°C.
- 🔹 TAM-133 —installed on two-chamber refrigerators (KShD-240, KShD-262) Has an extended temperature range and an additional contact for a signal lamp.
- 🔹 Danfoss 077B6 (or KP-15) - an imported analogue, often found in models after 2010. It is distinguished by increased accuracy and durability.
- 🔹 TAM-145 - used in modern refrigerators with the system No Frost (BS-145, BS-147. It has protection from moisture and expanded functionality.
It is important to consider that even within the same series of refrigerators, thermostats may differ in capillary tube length, mounting type and electrical parameters. For example, a thermostat for Biryusa-3M is not always suitable for Biryusa-3K, despite similar model names.
How to determine the thermostat model for your refrigerator
To choose the right thermostat, it is not enough to know only the series refrigerator. It is necessary to accurately determine marking of the original thermostatwhich is indicated on its body. Here's how to do it:
Unplug the refrigerator and defrost it (if required).
Remove the top cover of the refrigerator compartment (usually it is secured with latches or screws).
Find the thermostat - it is located next to knob for adjusting the temperature and is a plastic box with a thin tube (capillary) coming out of it.
Carefully disconnect the thermostat from the bracket and inspect its body. The marking is applied on the front or back side.
Typical marking of thermostats Biryusa looks like this:
- 📌
TAM-112-1M-15- where112series,1Mmodification,15length of the capillary tube in meters. - 📌
KP-15 A220-240V 50Hz— for imported thermostats Danfoss.
If the marking has been erased or the thermostat has already been removed, you can determine the appropriate model by refrigerator serial number (located on the nameplate inside the chamber or on the back). To do this, use official spare parts catalog or contact the service center.
Signs of a malfunctioning thermostat in the Biryusa refrigerator
The thermostat is an electromechanical device, and over time its contacts wear out, and the capillary tube loses its tightness. You can recognize a thermostat failure by the following symptoms:
- ❄️ The refrigerator does not turn on — the compressor is silent, the light inside is on. This indicates an open circuit in the thermostat.
- ⚡ The compressor runs without stopping —the thermostat does not open the contacts when the set temperature is reached.
- 🌡️ The temperature in the chamber does not correspond to the settings —too warm or, conversely, food freeze.
- 🔊 Clicks when turning the adjustment knob —a sign of wear of the contact group.
- 💧 Ice on the back wall (in models without No Frost) - thermostat does not turn off the compressor in time, which leads to excessive cooling.
Before blaming the thermostat, check:
- 🔌 The reliability of the plug connection to the socket.
- 🔋 The serviceability of the compressor (it should vibrate slightly during operation).
- 🔄 Correct installation of the adjustment knob (sometimes it gets lost when moving).
If the listed problems are excluded, and the symptoms persist, the thermostat is most likely faulty. For final diagnostics, you can check it with a multimeter.
How to check a thermostat with a multimeter?
To check, move the thermostat knob to the "Max" position (maximum cold) and measure the resistance between terminals 3 and 4. At room temperature it should be close to zero (contacts closed). Then immerse the capillary tube in ice water - the resistance should become infinite (contacts open). If this does not happen, the thermostat is faulty.

Step-by-step instructions for replacing the thermostat with your own by hand
You can replace the thermostat in the refrigerator yourself Turkish if you follow safety precautions and follow the instructions. You will need:
- 🔧 Phillips and flat head screwdriver.
- 🔌 Multimeter (for checking contacts).
- 🧰 Pliers.
- 📸 Camera (to record the connection diagram).
Procedure:
Unplug the refrigerator and defrost it (if required).
Remove the top panel of the refrigerator compartment. Usually it is attached to 2-4 screws under the cover or latches.
Disconnect the temperature control knob (it can be removed by pulling towards you or unscrewed).
Carefully disconnect the wires from the thermostat, having previously photographed or noted their location. Usually 4 wires are used:
- 🔴 Red - phase (power).
- 🔵 Blue - zero.
- 🟡 Yellow - signal lamp.
- 🟤 Green - grounding (if yes).
Unscrew the thermostat from the bracket and remove it along with the capillary tube. Be careful - the tube is fragile!
Install the new thermostat in the reverse order, connecting the wires according to the diagram.
Place the capillary tube into its original position (it should be secured along the evaporator).
Assemble the refrigerator, plug it in and check the operation within 1-2 hours.
☑️ Check after replacing the thermostat
If after replacement the refrigerator does not turn on or is unstable, check:
- 🔌 The wires are connected correctly (check the photo).
- 🔧 Reliability of fastening of the capillary tube (it should not touch the walls).
- 📏 Length of the tube - if it is too short or long, the thermostat will not work correctly.
Common mistakes when replacing a thermostat and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns or incorrect operation of the refrigerator. Here are the most common of them:
- ⚡ Incorrect connection of wires —for example, phase and zero are mixed up. This can lead to a short circuit or failure of the compressor.
- 🔄 Using a thermostat with the wrong length capillary - if the tube is too short, the thermostat will operate prematurely, and if it is long, it will be delayed.
- 🛠️ Damage to the capillary tube during installation - even a small bend or crack will lead to gas leakage and inoperability of the thermostat.
- 🔧 Loose attaching the thermostat - vibration during compressor operation can cause breakage of contacts.
- 🌡️ Failure to comply with the temperature conditions during testing —the thermostat is tested at room temperature (about +20°C).
To avoid these mistakes:
- 📸 Take photographs of each stage of disassembly —this will help to assemble the refrigerator correctly.
- 🔍 Check the thermostat before installation with a multimeter.
- 📏 Check the length of the capillary tube with the original.
- 🔌 Use heat-shrink tubing to insulate the contacts.
FAQ: Answers to frequently asked questions about thermostats Biryusy
Is it possible to replace the TAM-112 thermostat with a Danfoss 077B6 without modifications?
Yes, Danfoss 077B6 is a complete analogue TAM-112 in terms of electrical parameters and fastenings. However, make sure that the length of the capillary tube is the same (it may be 10–15 cm shorter). If the tube is longer, you can carefully bend it, but not bend it! Danfoss it may be 10–15 cm shorter). If the tube is longer, you can carefully bend it, but do not bend it!
How to check if the thermostat is working without removing it from the refrigerator?
Disconnect the refrigerator from the network, remove the protection from the thermostat terminals and measure the resistance between contacts 3 and 4. At room temperature it should be close to zero (contacts closed). Then turn the thermostat knob to the "Off" position - the resistance should become infinite. If this does not happen, the thermostat is faulty.
How much does it cost to replace a thermostat in a service center?
The cost of replacing a thermostat in official service centers Biryusa is from 1,500 to 2,500 rubles (excluding the cost of spare parts). In private workshops the price may be lower - from 1,000 rubles. If the refrigerator is under warranty, the repair is free.
Is it possible to repair the thermostat or just replace it?
Thermostats THERE i Danfoss are not subject to repair - these are non-separable devices with a sealed capillary system. If the contacts are burnt, they can be cleaned, but this is a temporary solution. If there is a gas leak from the tube or mechanical damage, a complete replacement is required.
Why does the new thermostat click, but the refrigerator does not turn on?
Clicks indicate activation of the contact group, but the failure to start the compressor may be due to:
- 🔌 Incorrect connection of wires (phase/zero reversed).
- 🔋 Malfunction of the compressor starting relay.
- 🛠️ Open circuit in the power supply (check the fuse).
Ring the circuit multimeter from the thermostat to the compressor.
