Replacing the thermostat in a Stinol refrigerator: instructions with photos and nuances

Refrigerators Stinol are famous for their reliability, but even they are not immune from breakdowns. One of the most common malfunctions is the failure of the thermostat (thermostat), which is responsible for maintaining the set temperature. If your unit stops freezing, constantly works without stopping, or, on the contrary, turns off ahead of time, with an 80% probability this unit is the culprit.

The service center will charge from 2,500 to 5,000 rubles for replacing the thermostat, but if you have direct hands and basic tools, you can do it yourself. This article takes into account the features of models step-by-step analysis of the process taking into account the features of the models Stinol 101/103/107/110 and their analogs, as well as tips on how to avoid common mistakes.

Signs of a faulty thermostat

Before you take a screwdriver, make sure that the problem is in the thermostat. Here 5 obvious symptomsthat indicate its breakdown:

• 🔴 The refrigerator does not turn on at all (the light inside is on, but the compressor is silent).
• ❄️ The freezer is working, but the main compartment is too warm (or vice versa).
• ⏳ The compressor runs non-stop for >12 hours, the walls are covered with ice.
• 🌡️ The temperature in the chambers does not correspond to the one set on the regulator (for example, at position "3" in the refrigerator +15°C).
• 🔄 After defrosting, the unit does not starts or turns on only after physical impact on the thermostat knob.

If at least one of these signs appears, there is a high probability that the thermostat stuck in one position or completely out of order. Before replacing, be sure to check:

• 🔌 The reliability of connecting the plug to the socket (sometimes the problem is in the contacts).
• 💡 The functionality of the light bulb inside (if it doesn’t light up, the problem may be in the control unit).
• 🧊 Cleanliness of the condenser (a dusty grill on the back wall leads to overheating).

⚠️ Attention: On models Stinol with electronic control (series RF-3xx, RN-4xx), the thermostat can be integrated into the board. In this case, independent repair is not recommended - diagnostics by a specialist is required.

Which thermostat is suitable for Stinol

In refrigerators Stinol two types of thermostats are used:

1. Mechanical (series K-59, TAM-133, TAM-125) - installed on models up to 2010.
2. Electronic (series RT-2, RT-3) - found in new units with a display.

For most household models (Stinol 101, 103, 107, 110), a thermostat TAM-133-1M or its analogue K-59-L1953is suitable. These parts are interchangeable, but when purchasing, be sure to check:

Where buy:

• 🛒 Official service centers Stinol (1 year warranty on the part).
• 🔧 Stores of spare parts for refrigerators (for example, "Holod-Service", "TeploHolod").
• 🌍 Online platforms: AliExpress (cheaper, but takes a long time), Yandex Market (fast, but more expensive).

⚠️ Attention: There is a high risk when buying in markets or from hand run into a used part. Check the integrity of the capillary tube - it should be free of kinks and cracks. A damaged tube will lead to incorrect operation of the thermostat.

Preparation for replacement: tools and safety

For work you will need:

• ⚒️ Screwdrivers: Phillips (PH2) and flat (3-4 mm).
• 🔧 8 or 10 mm wrench (for attaching the thermostat).
• 📸 Phone or camera (to record the location of the wires).
• 🧲 Magnet or marker (for marking the wires).
• 🧤 Rubber gloves (protection from sharp metal edges).

Secure the process:

1. Unplug the refrigerator and wait for complete defrosting (at least 6 hours).
2. Remove all products and shelves - they will interfere with access to the thermostat.
3. Prepare the workplace: lay cardboard or cloth so as not to scratch the floor.

If yours Stinol s system No Frost, before disassembling be sure to:

1. Remove the protective cover from the fan (it is secured with latches).
2. Disconnect the fan power connector (usually white or gray).

Step-by-step replacement instructions thermostat

Disassembling the refrigerator Stinol has nuances depending on the model. Below is a universal instruction suitable for 90% of cases.

Step 1: Removing the temperature control knob

The thermostat knob is attached either to a latch or to a screw. Carefully pry it open with a flat-head screwdriver (if there is a latch) or unscrew the screw (usually hidden under a decorative plug). In some models (Stinol 107), the handle is removed by turning it counterclockwise until it clicks.

Step 2: Removing the control panel

The panel is secured with 2-4 screws (depending on the model). Unscrew them and remove the panel by pulling it towards you. Under it you will see:

• The thermostat itself (plastic or metal body with a tube).
• A bundle of wires going to the compressor and the light bulb.
• A capillary tube attached to the evaporator.

Where Is there a thermostat in Stinol 101?

In single-chamber models (for example, Stinol 101) the thermostat is located inside the chamber, on the right under the top shelf. It is closed with a plastic casing, which is fastened with two screws.

Step 3: Disconnecting the wires

This is the most critical step. Do not pull the wires by force —first take a photo of the connection diagram or mark them with a marker. Typical pinout for Stinol:

• 🔴 Red/orange - phase (comes from the compressor).
• 🔵 Blue/black - zero (common wire).
• 🟢 Green/yellow - grounding (if any).
• 🟡 Yellow/white - defrost sensor (in models with No Frost).

Wires can be secured with terminals or soldering. In the first case, simply loosen the screws of the terminal block; in the second, carefully cut the wires with wire cutters, leaving a margin of 10–15 mm for a new connection.

Step 4: Removing the old thermostat

The thermostat is attached to the refrigerator body with 1-2 screws. Unscrew them and carefully pull out the part without bending the capillary tube. If the tube is attached to the evaporator with a clamp, loosen it and remove it.

Carefully inspect the place where the tube is attached to the evaporator. If there are signs of corrosion or damage, clean the surface with sandpaper before installing the new thermostat.

Step 5: Installing the new thermostat

Reverse process to removal:

1. Attach the capillary tube of the new thermostat to the evaporator (use an old clamp or plastic tie).
2. Install the thermostat in place and secure with screws.
3. Connect the wires according to the markings or photographs. If the wires are cut, use terminal strips or soldering.
4. Put on the regulator knob and secure it.

Step 6: Check operation

Connect the refrigerator to the network and set the thermostat knob to position "3" (medium temperature). After 10–15 minutes:

• 🔊 The compressor should start working (slight humming).
• 🌡️ The temperature in the chamber should begin to drop (check with your hand after 30 minutes).
• 💡 The light inside should light up when opened doors.

⚠️ Attention: If after replacement the refrigerator does not turn on, check:

• The correct connection of the wires (especially phase and neutral).
• The integrity of the capillary tube (it should not be pinched).
• Reliability attaching the thermostat to the body (vibration can damage the contacts).

If the problem remains, the compressor or start relay may be faulty.

Typical mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing a thermostat. Here TOP-5 errors and their consequences:

Another common problem is incorrect installation of the regulator handle. If it is not fixed in the grooves, the thermostat will not correctly transmit the position to the mechanism. In this case:

1. Remove the handle and check the integrity of the plastic latches.
2. Make sure that the thermostat rod fits into the groove of the handle without play.
3. If necessary, sharpen the groove a file or replace the handle.

What to do if the replacement does not help

In 10–15% of cases, replacing the thermostat does not solve the problem. This means that the cause of the malfunction is in another node. Carry out additional diagnostics:

• 🔧 Compressor start relay: if there is a malfunction, the compressor does not start or hums and turns off. Check the relay contacts with a multimeter (the resistance between the terminals should be 20–40 ohms).
• ❄️ Freon leak: if the compressor runs but does not freeze, there may be no refrigerant in the system. Signs: oil on the tubes, freezing in only one corner of the evaporator.
• 🔌 Electronic control unit: in models with a display (Stinol RF-3xx), the board may burn out. Symptoms: errors flash on the screen, does not respond to buttons.
• 🌀 Fan No Frost: if it does not rotate, the cold does not enter the chambers. Check if the blades are blocked by ice.

If you are not confident in your abilities, it is better to call a specialist. For example, eliminating a freon leak requires special equipment (vacuum pump, refrigerant cylinder) and skills.

⚠️ Attention: In refrigerators Stinol with an inverter compressor (series INV), independent repairs can lead to failure of an expensive module. Contact the service center.

Cost of repairs in the service vs independent replacement

Let's calculate how much it will cost to replace the thermostat in Stinol in different ways:

It is most profitable to buy a thermostat yourself and invite a specialist only for installation. This way you will save up to 50% of the cost. For example, a thermostat TAM-133-1M on AliExpress costs ~800 ₽, and the service center will charge 2000–2500 ₽ for it.

If you decide to repair yourself, consider the hidden costs:

• 🔧 Tool (if there are no screwdrivers/keys) - from 300 ₽.
• 🚗 Delivery of spare parts (if you order online) - 200–500 ₽.
• ⏳ Time (if never repaired refrigerators, you can spend the whole day).

FAQ: Frequently asked questions about replacing the thermostat

Is it possible to replace the thermostat without defrosting the refrigerator?

No. Working with electrical components in a damp environment is dangerous and there is a high risk of short circuiting. In addition, when defrosting, it is easier to dismantle the control panel and gain access to the thermostat. An exception is if the refrigerator is already defrosted (for example, it hasn’t worked for several days).

How to check the thermostat with a multimeter?

Put the multimeter into dial mode. At room temperature, pins 3 and 4 (counting from left to right) should be closed. Turn the thermostat knob: when set to “0” the contacts open, when set to “7” the contacts close. If there is no reaction, the part is faulty.

Important: Before checking, disconnect the thermostat from the refrigerator!

What to do if after replacement the refrigerator works without stopping?

Probable reasons:

1. Wires are connected incorrectly (check phase and zero).
2. The capillary tube does not fit tightly to the evaporator (must be secured with a clamp).
3. The new thermostat is defective (check it with a multimeter).
4. Freon leak (refilling the system is required).

Start by checking the wire connections and tube fastening.

Is the thermostat from the Atlant refrigerator suitable for Stinol?

No, even if the parts are similar in appearance. Thermostats Atlant (for example, K-59) have a different graduation and capillary tube length. For Stinol you need the original TAM-133-1M or its exact analogue K-59-L1953.

How much how long does it take to replace a thermostat?

On average:

• Defrosting - 4–6 hours.
• Dismantling/installation - 1–1.5 hours.
• Operation check - 30 minutes.

If this is your first time doing repairs, reserve time for the whole day. Experienced craftsmen can do it in 2-3 hours.
