Where is the thermostat in the Biryusa refrigerator: search by model with photos and schemes

The thermostat (or thermostat) is the “brain” of the refrigerator Biryusawhich controls the temperature in the chambers and controls the operation of the compressor. When this unit fails, the equipment stops freezing, works without stopping, or, conversely, turns off too early. But before changing the part, you need to find it - and here a surprise awaits the owners: depending on the model Biryusa the thermostat can be located in completely different places.

In this article we will figure out where to look for the thermostat in refrigerators Biryusa of different series - from old Soviet models to modern ones (2010–2026). You will learn how to distinguish a thermostat from other sensors, what tools are needed to access it, and why in some cases it is easier to call a specialist than to delve into the design yourself. And for clarity, we present diagrams and photos of real refrigerators - without abstract descriptions.

1. What does the thermostat look like in the Biryusa refrigerator?

Before looking for a part, you need to understand what exactly you are looking for. Thermostat Turquels is a small plastic or metal device with:

• 🔌 Terminal block (2-4 contacts for wires).
• 📏 Bellows tube (thin copper or aluminum tube that goes deep into the chamber).
• ⚙️ Adjusting screw (sometimes hidden under the cover).
• 🏷️ Marking (for example, K-59, TAM-133, Danfoss 077B6).

Externally, it may resemble a relay or a timer, but it is easy to distinguish: the thermostat is always connected to capillary tube, which is attached to the evaporator (the back wall of the refrigerator compartment). In modern models, the thermostat is often hidden under a plastic one. casing, and in old ones (for example, Turks The thermostat is often hidden under a plastic casing, and in older ones (for example, KShD-240) - it is in plain sight.

It is important not to confuse the thermostat with:

• 🔥 Thermal fuse (a small part with two legs, usually soldered to the compressor).
• ❄️ Defrost sensor (in models with No Frost; looks like a plastic cylinder).
• ⚡ Start relay (black box on the compressor).

2 Where is the thermostat in old Biryusa models? (until 2010)?

In refrigerators Biryusa of the Soviet and early post-Soviet period (series KShD, KSHN, KShT), the thermostat was located as conveniently as possible for repair - inside the refrigerator compartment, on the right wall. It is easy to find if:

1. Disconnect the refrigerator from the network.
2. Remove all products from the top shelf.
3. Remove the plastic cover (if any) or simply pull the temperature control knob - the thermostat is hidden behind it.

Typical models with this arrangement:

• 🏺 Biryusa KShD-240 (and modifications KShD-240/60, KShD-240/100).
• ❄️ Biryusa KSHN-260 (single-chamber with bottom freezer).
• 🔄 Biryusa KShT-220 (double-chamber with top freezer).

In these models, the thermostat is mounted on two screws or latches. To remove it, just disconnect the terminals (remember their location!) and carefully remove the tube from the mount on the evaporator. In old Biryusa refrigerators, the thermostat is often combined with an adjustment knob - this simplifies diagnostics, but complicates replacement (you will have to select a similar model with the same scale).

3. Modern Biryusa models (2010–2026): where to look for a thermostat?

In refrigerators Biryusa new generation (series KShDS, KSDN, KSHDNF with the No Frost system), the thermostat was moved to less accessible places. Its location depends on the type of cooling system:

In models with electronic control (for example, Biryusa KSHDNF-312) instead of a mechanical thermostat, a temperature sensor (thermistor) is used, which transmits signals to the control board. In this case, there is no “thermostat” in the classical sense - it is replaced by an electronic module, located:

• 📱 On the back wall of the refrigerator (main board).
• 🌡️ Inside the chamber (a small sensor on a wire attached to the evaporator).

If your model is equipped with a display. (for example, Biryusa KSHDNF-312W), then it most likely does not have a mechanical thermostat. In this case, the fault may lie in:

• 🔌 Control board (diagnostics with a multimeter is required).
• 🌡️ Temperature sensor (tested by resistance).
• ❄️ Defrosting system (for No Frost).

4. Step-by-step instructions: how to find the thermostat in the Biryusa refrigerator?

So as not to waste time on useless searches, follow this algorithm:

1. Determine the refrigerator model.

   The model number is indicated on the sticker inside the chamber (usually on the left) or on the back wall. For example: KSHDN-256/200 or Biryusa 145S.

2. Check the control type.

   If there is a mechanical knob with numbers (1–7) - the thermostat is mechanical. If there is a display and buttons - electronic.

3. Remove the cover (if necessary).

   In models KShDS and KSHN the thermostat is hidden under a plastic panel on the right wall. B No Frost - behind the decorative panel inside the chamber.

4. Look for a capillary tube.

   The thermostat is always connected to a thin metal a tube that goes to the evaporator.

If the thermostat is found, but you are not sure that it is the one, pay attention to the markings. In Biryusha most often found:

• 🔢 K-59 (the most common; suitable for most models).
• 🔢 TAM-133 (for old refrigerators).
• 🔢 Danfoss 077B6 (in new models with No Frost).
• 🔢 Ranco K-56 (less common, but interchangeable with K-59).

⚠️ Attention: In refrigerators Biryusa with system No Frost The thermostat can be hidden under a layer of foam. If you are not confident in your abilities, it is better not to take risks - if dismantled incorrectly, you can damage the thermal insulation.

5. How to check the thermostat for functionality?

If the thermostat is found, but the refrigerator is not working correctly, you need to check it with a multimeter. To do this:

1. Disconnect the refrigerator from the network.
2. Remove the terminals from the thermostat (take a photo of their location!).
3. Switch the multimeter to resistance testing mode (200 Ohm).
4. Connect the probes to contacts 3 and 4 (usually these are the outer terminals).

Results:

• 🔄 At room temperature resistance should be 0 Ohm (contacts are closed).
• ❄️ When cooling (place the thermostat in the freezer for 10 minutes) the resistance should become ∞ (open).

If the resistance does not change, the thermostat is faulty. Also check:

• 🔌 The integrity of the wires (there should be no breaks or melting).
• 🌡️ Capillary tube (should not be pinched or damaged).

What to do if the thermostat fails the test?

If the thermostat is faulty, it needs to be replaced. For Biryusa models, analogues are suitable:

- K-59 → instead of TAM-133 (fastening needs modification)

- Danfoss 077B6 → complete analogue for No Frost

- Ranco K-56 → interchangeable with K-59 (but the adjustment may vary)

When replacing, be sure to move the capillary tube to a new location so that it fits tightly to the evaporator.

6. Common mistakes when finding and replacing a thermostat

Even experienced craftsmen sometimes make mistakes that lead to new breakdowns. Here's what you cannot do when working with a thermostat Turks:

• ⚡ Confuse the wires when connecting.

  If you confuse the terminals, the refrigerator will either not turn on or will work without stopping. Always take photographs of the original connection!

• 🔨 Bend the capillary tube.

  This will lead to loss of tightness and incorrect operation of the thermostat. The tube should lie freely, without kinks.

• 🧊 Ignore checking the seal.

  If after replacing the thermostat the refrigerator still does not freeze, check whether the door closes tightly. A worn seal can be the real cause of failure.

• 🔥 Work under voltage.

  Even if you are “very careful”, the risk of a short circuit when the power is connected is too high.

⚠️ Attention: In refrigerators Biryusa s two compressors (for example, KShDN-312) can be two thermostats - separately for the refrigerator and freezer compartments. If you replace only one, make sure that the problem is in it, and not in the second one or in the control board.

If after replacing the thermostat the refrigerator:

• 🔄 Does not turn on at all → check the fuse and start relay.
• ❄️ Works without stopping → perhaps the new thermostat is incompatible or the capillary tube is installed incorrect.
• 🌡️ Freezing too much → adjust the screw on the thermostat (turn counterclockwise ¼ turn).

7. When is it better to call a technician rather than repair it yourself?

Replacing a thermostat in Biryusa is a task of average complexity, but in some cases it is better to trust a professional:

• 🛠️ The refrigerator is under warranty.

  Do-it-yourself repairs will void the warranty. Contact the service center Biryusy.

• ⚡ Model with electronic control.

  If instead of a mechanical thermostat there is a sensor + board, diagnostics requires experience with electronics.

• 🏗️ The thermostat is hidden under foam plastic.

  In models No Frost sometimes you have to cut the thermal insulation - without experience this is fraught with loss of cold.

• 🔥 The problem is not in the thermostat.

  If nothing has changed after replacement, the reason may be in the compressor, freon leak or circuit board controls.

Average cost of replacing a thermostat in service:

• 💰 Mechanical thermostat (K-59, TAM-133) - 1,500–2,500 ₽ (with work).
• 💰 Sensor + board (for electronic models) — 3,000–5,000 ₽.
• 💰 Departure of a technician to your home — 1,000–1,500 ₽ (depending on the region).

FAQ: Frequently asked questions about the thermostat in the Biryusa refrigerator

🔍 How to understand that the thermostat is broken and not the compressor?

Main symptoms of a malfunction thermostat:

• The refrigerator does not turn on at all (but the light inside is on).
• The compressor works without stopping, but the temperature in the chamber does not drop.
• The refrigerator turns on for 5-10 seconds and turns off.

If the compressor buzzes, but does not start or gets very hotthe problem is most likely in it or in the start relay.

🛠️ Is it possible to replace the K-59 thermostat with a Danfoss 077B6?

Technically yes, but:

• Danfoss 077B6 short-stroke (responds faster to temperature changes).
• May differ connectors —you will have to resolder the terminals.
• In some models Turks with K-59 after replacing with Danfoss the refrigerator starts working excessively intense (adjustment needed).

It is better to select complete analogue (for example, K-59 to K-59 or TAM-133 to TAM-133).

❄️ Why did the refrigerator begin to freeze slightly after replacing the thermostat?

Probable reasons:

• Capillary tube does not fit tightly k evaporator.
• New thermostat not calibrated (you need to tighten the adjusting screw).
• When replacing damaged seal doors.
• In the system not enough freon (needs refilling).

Check if air has entered into the capillary tube - this is a common mistake when replacing it yourself.

📌 Where to buy a thermostat for Biryusa?

Original and similar thermostats are sold:

• 🛒 B spare parts stores for refrigerators (for example, "Rembyttekhnika", "Holod-Service").
• 🌍 On marketplaces (Wildberries, Ozon, AliExpress - but be careful with fakes!).
• 🔧 In service centers Biryusa (warranty on parts).

Average price:

• K-59 — 800–1 200 ₽.
• Danfoss 077B6 — 1 500–2 000 ₽.
• TAM-133 - 600–900 ₽.

🔄 Is it possible to repair the thermostat, or just replace it?

Thermostats cannot be repaired - these are sealed devices with gas inside. If it fails, it can only be replaced. Exception:

• 🔌 Contacts are oxidized —they can be cleaned.
• 🔄 The capillary tube is loosened —it can be fixed.

In all other cases (open circuit, gas leak from the bellows) replacement is required.
