Refrigerators Stinol are one of the most common in Russia due to their reliability and affordable price. But even such equipment requires maintenance over time. One of the key elements of the cooling system is temperature sensor, which controls the operation of the compressor and maintains the specified mode. If the refrigerator begins to freeze poorly, turns on too often or, conversely, turns off for a long time, the problem may lie precisely there.
In this article you will find precise sensor location diagrams in popular models Stinol (100, 101, 103, 107, etc.), you will learn how to check them without calling a technician, and what to do if they break down. We will also look at why in some cases it is not the sensor itself that is to blame, but thermostat or electronic control unit this will help avoid unnecessary expenses on replacing serviceable parts.
How the temperature sensor works in a Stinol refrigerator
A sensor (or thermistor) is a semiconductor element that changes resistance depending on temperature. In refrigerators Stinol he transmits data to control board or a mechanical thermostat, which regulate the operation of the compressor. If the sensor fails, the system receives incorrect signals, which leads to:
- 🔹 Continuous operation of the compressor (the refrigerator does not turn off).
- 🔹 Excessive freezing rear wall or freezer.
- 🔹 Lack of cooling (the compressor does not turn on).
- 🔹 Spontaneous defrosting products.
In modern models Stinol (for example, STN 167 or STN 185) is used digital sensorconnected to the electronic unit. In old ones (for example, Stinol-101) — mechanical thermostat with a capillary tube, which is often confused with a sensor. Let's figure out where and what to look for.
Where is the temperature sensor: diagrams for different models
The location of the sensor depends on type of system. control (electronic or mechanical) and refrigerator design (single-chamber or dual-chamber). Below are proven diagrams for popular series.
1. Single-chamber refrigerators (Stinol-100, 101, 103, 107)
In these models, the sensor is usually built into the thermostat (mechanical temperature controller) itself. located:
- 🔧 Inside the refrigerator compartment, under the plastic cover on the right wall (next to the light bulb).
- 🔧 Sometimes - outside, on the back wall of the case (under the decorative panel).
The capillary tube of the thermostat runs along the evaporator. Inspect it carefully for damage - often the problem lies in the leak of freon from the tube, and not in the sensor itself.
2. refrigerators (Stinol-104, 105, 167, 185)
Here the system is more complex: there can be two or three sensors (separately for the refrigerator compartment, freezer and, sometimes, for the freshness zone):
| Model | Refrigerator compartment sensor | Freezer compartment sensor |
|---|---|---|
| Stinol-104/105 | On the evaporator (behind the back panel), next to the fan | Inside the freezer compartment, on the top wall |
| Stinol-167/185 | Under the plastic cover on the ceiling of the chamber | On the evaporator of the freezer (behind the panel) |
| Stinol-200 and newer | Mounted into the electronic unit (on the back wall) | Similarly, but with a separate connector |
In models with a system No Frost (for example, Stinol NF-335) the sensors are often hidden behind internal panels and connected to the board through connectors. To get to them, you will have to remove the back wall. refrigerator compartment.
How to check the temperature sensor: step-by-step instructions
If you suspect a sensor malfunction, first rule out other causes (for example freon leak or compressor failure). For diagnosis you will need multimeter (in resistance measurement mode).
Disconnect the refrigerator from the mains
Remove the protective panels (if necessary)
Find the sensor according to the diagram above
Prepare a multimeter ("200 kOhm" mode)
Record readings at different temperatures-->
Step 1: Removing the sensor
Carefully disconnect the sensor connector from the board or thermostat. In mechanical models (Stinol-101) it may be necessary to fastened with 2–3 screws. complete dismantling of the thermostat — it is attached with 2-3 screws.
Step 2: Resistance measurement
Connect the multimeter probes to the sensor contacts and measure the resistance:
- 🌡️ At room temperature (+20°C): ~5–7 kOhm.
- 🧊 When cooled (place the sensor in ice, +0°C): ~27–30 kOhm.
- ❄️ When heated (hold in hand, +30°C): ~2–3 kOhm.
If the resistance not changes or shows 0/∞ (open), the sensor is faulty.
Step 3: Checking the circuit
Make sure there is no wire breaks between the sensor and the board. To do this, test the circuit with a multimeter in the continuitiesmode. If there is no signal, look for cable damage.
What to do if the sensor is working but the refrigerator is not working?
If the sensor shows correct values, the problem may be:
1. Control board (diagnostics of the electronic block).
2. Thermostat (in mechanical models - replace it entirely).
3. Compressor (check the starting relay and windings).
4. Freon leakage (you need a specialist with equipment for refilling).
Signs of a malfunctioning temperature sensor
Failure of the sensor does not appear immediately - at first the refrigerator is malfunctioning. Please note. pay attention to the following symptoms:
- ⚠️ The compressor works without stopping, but the temperature in the chamber does not drop to normal.
- ⚠️ The refrigerator turns off too quickly and does not have time to cool the food.
- ⚠️ A thick layer of ice forms on the back wall (in models without No Frost).
- ⚠️ The electronic panel shows an error (for example,
E1,E2or the temperature indicator blinks).
In models with a display (for example, Stinol STN 185), a sensor malfunction is often accompanied by error code. For decoding, see the instructions for the refrigerator.
How to replace a temperature sensor yourself
If diagnostics confirm a breakdown, the sensor can be replaced without calling a technician. The main thing is to choose analogue with the same characteristics (resistance and type of connection). For models Stinol the following sensors are suitable:
- 🔧 KTY83-122 (for electronic models).
- 🔧 AMT1004 or NTC 10k (universal).
- 🔧 Thermostat K-59 (for mechanical refrigerators).
Replacement order:
- Disconnect the refrigerator from the mains.
- Remove the protective panels (if necessary).
- Disconnect the sensor connector from the board or thermostat.
- Install a new sensor, connect the connector.
- Close the panels, turn on the refrigerator and check the operation.
⚠️ Attention: In models with the system No Frost after replacing the sensor, it may required resetting the settings (turn off the refrigerator for 10 minutes, then turn it on again). If the error remains, the problem is in the control board.
Frequent errors during diagnostics and repair
Many users confuse a sensor malfunction with other failures. Here are typical errors:
- 🔸 Ignoring the thermostat check. In mechanical models (Stinol-101), the sensor is part of the thermostat, and the entire assembly needs to be replaced.
- 🔸 Incorrect resistance measurement. The sensor must be tested at different temperatures, not just room temperature.
- 🔸 Replacing a working sensor. Sometimes the problem is in the oxidized contacts of the connector - it is enough to clean them with alcohol.
- 🔸 Use of incompatible spare parts. The sensor from Indesit may not fit Stinol even with the same resistance.
If after replacing the sensor the refrigerator is unstable, check:
- 🔹 Tightness of the door seal (wear rubber bands leads to incorrect readings of the sensor).
- 🔹 Setting the thermostat (in mechanical models, adjustment is carried out by rotating the screw inside the thermostat).
FAQ: Frequently asked questions about temperature sensors in Stinol
Is it possible to repair a temperature sensor, or just replace it?
Temperature sensors (thermistors) cannot be repaired - they can only be replaced. Exception: mechanical thermostats in older models (Stinol-100), where sometimes cleaning the contacts or filling the capillary tube helps (but this is a temporary solution).
Which sensor is suitable for Stinol-103?
In Stinol-103 a mechanical one is used thermostat K-59 (or its analogues Danfoss 077B6, Ranco K-59). To replace, take a thermostat with the same capillary tube (length ~1 m). In electronic modifications (if any) - sensor NTC 10k.
The Stinol refrigerator does not turn off and gets very cold. Is this a sensor?
Most likely, yes. But first check:
- If the mode is set super freezing (turn it off).
- Serviceability door seal (if it wears out, the refrigerator works for wear and tear).
- Thermostat (in mechanical models) - its sticking leads to continuous operation of the compressor.
If everything is in order, test the sensor according to the instructions above.
Where to buy a sensor for Stinol?
Original sensors and thermostats are sold:
- In service centers Stinol (search in your city).
- At AliExpress (search by refrigerator model or sensor number).
- In stores of spare parts for household appliances (for example, 220-volt.ru, All-Spare.ru).
Cost: from 300 rubles for a universal NTC sensor to 1500 rubles for an original thermostat.
Is it possible to do without a sensor temporarily?
No. Without a sensor, a control board or the thermostat will not receive temperature data, and the compressor either will not turn onor will burn out from continuous operation.. As a last resort, you can connect a temporary sensor (for example, from another equipment), but only if its characteristics match.
