Search thermostat in Turkish brand household appliances Beko — a task that requires an understanding of the design of a specific model, since the manufacturer uses different assembly layouts. Unlike Soviet units, where the sensor was always visible, in modern systems No Frost and combined models, access to the element is often hidden by decorative panels. Incorrect determination of the installation location can lead to damage to the wiring or disruption of the seal of the chambers.
Before proceeding with disassembly, it is necessary to disconnect the device from the power supply, since the work will be carried out in close proximity to electrical contacts. The thermostat in refrigerators Beko is responsible for the cyclic operation of the compressor, and its incorrect operation leads to either a permanent freezer or complete defrosting of food. Understanding where exactly this unit is hidden will save you time and nerves.
The principle of operation and types of thermostats in Beko technology
A thermostat, or thermostat, is a mechanical or electronic device that reads the temperature inside the refrigeration chamber and sends a signal to turn the compressor on or off. In classic models with a drip defrosting system, mechanical sensors with a long length, the end of which is immersed in the evaporator, are most often found. Electronic models are equipped with thermistors (NTC sensors), which have no moving parts and are controlled by a board. Beko with a drip defrosting system, mechanical sensors with a long length are most often found capillary tube, the end of which is immersed in the evaporator. Electronic models are equipped with thermistors (NTC sensors), which have no moving parts and are controlled by a board.
The mechanical thermostat is activated due to the expansion or contraction of freon inside a sealed flask, which opens or closes the contacts. This is a reliable system, but requires periodic calibration. In more expensive lines Beko is used electronic control, where the temperature sensor is part of the overall logical circuit. The difference in design dramatically affects where exactly the required element will be located.
It is important to understand that in refrigerators with a system No Frost the thermostat is often replaced by defrost and air temperature sensors, which are scattered across different zones of the evaporator. If you are looking for a classic “twist” regulator, it may not be there at all, since control is carried out through a digital display on the door or a hidden panel.
⚠️ Attention: An attempt to replace a mechanical thermostat with an electronic one (or vice versa) without re-soldering the electrical circuit and changing the control logic will lead to failure of the compressor or control board.
Modern models Beko often use combined systems, where the main temperature control takes over electronic module, and the mechanical thermostat remains only as an emergency limiter or is absent completely. Therefore, before searching for a physical part, be sure to study the technical data sheet of your device.
Location in models with a weeping evaporator
In classic single-chamber refrigerators Beko and two-chamber models of the old series with a drip defrosting system, the thermostat is easiest to find. Traditionally, manufacturers have placed a mechanical temperature control unit inside the refrigerator compartment to minimize the length of the capillary tube. In most cases, thermostat is hidden behind a plastic casing, which also houses the lighting lamp.
To access the assembly, you will need to remove the top cover of the lamp shade. The mounting screws can be hidden under decorative plugs or located inside the light bulb itself (you need to carefully unscrew the shade). After removing the plastic, you will have access to the electrical contacts and the thermostat housing. In some modifications Beko the regulator itself can be moved outside the chamber, to the back wall of the case, but the control knob always remains inside.
- 🔍 Look for a plastic casing with the inscription "Temperature Control" or simply with a temperature gradation in the upper part of the refrigerator compartment.
- 🔧 For dismantling, you will most often need a Phillips screwdriver and a flat blade for prying up the plastic latches.
- ❄️ The capillary tube in such models passes through the door seal or a special hole in the chamber wall to the evaporator.
If you have removed the lampshade but do not see the thermostat, check the side walls of the chamber. In rare cases, especially in narrow models Beko, the control unit can be moved to the side or integrated into the smart home control system without a visible mechanical regulator. In such situations, the adjustment knob may be absent as such, and adjustments are made using buttons on the external panel.
⚠️ Attention: When removing the lamp shade, be extremely careful with the plastic latches. Plastic in old refrigerators Beko becomes brittle from the cold and can crack with a sharp jerk. Warm up the fastening points with a hairdryer if the plastic is very hardened.
Inside the casing you will see itself mechanical unit with wires suitable for it. This is the main candidate for replacement if the refrigerator stops turning off or, conversely, does not turn on. Check the integrity of the contacts and the absence of traces of oxidation or carbon deposits.
Search for sensors in No Frost and Full No Frost systems
The situation changes dramatically when it comes to refrigerators Beko with the system No Frost. In such units, a classic thermostat with a rotary knob inside the chamber is often missing. Instead, a group of thermal sensors (thermistors) located in various areas of the evaporator and air ducts is responsible for maintaining the temperature regime. Their search requires partial disassembly of the internal space.
The main air temperature sensor, which functionally replaces the thermostat, in models Beko No Frost is usually located on the back wall of the refrigerator compartment, hidden behind a plastic panel. To get to it, you need to completely empty the chamber of food, remove the shelves and dismantle the back wall. Often this sensor is located in the upper part, closer to the outlet of cold air from the freezer compartment.
The freezer compartment of the system No Frost also has its own sensors. They control the evaporator temperature and the presence of ice on the defrost heating element. If this particular element fails, the refrigerator may work non-stop, freezing like a fur coat, or it may stop freezing altogether. The location of the sensors in the freezer is often hidden behind a removable panel on the back wall or side wall. Accessing the insides of the evaporator in models is a labor-intensive process. You will have to remove not only the shelves, but also possibly the top lid of the freezer or even remove the door for easier access. In some models Beko often hidden behind a removable panel on the back wall or side wall.
Access to the insides of the evaporator in No Frost models is a labor-intensive process. You will have to remove not only the shelves, but also possibly the top lid of the freezer or even remove the door for easier access. Some models Beko sensors are pressed into polyurethane foam insulation, which makes their replacement extremely difficult without damaging the case.
- 🌡️ The air temperature sensor in No Frost usually has a white or gray plastic tip and is attached to a clip to wall.
- 🧊 The defrost sensor is always located directly on the evaporator tubes, often at the bottom or in the middle of the "comb".
- ⚡ All wires in the system No Frost pass through harnesses that can be laid under the casing, which requires care when disassembly.
If you are looking for where the thermostat is located in Beko No Frost, and do not find anything like a knob inside the camera, then the control is completely electronic. In this case, the “thermostat” is a combination of a control board and several NTC resistance sensors.
Access through the rear panel and compressor compartment
There is a category of refrigerators Beko, where the thermostat or its emergency analogue is located outside, in the compressor area. This is typical for some industrial models or very old household series. In modern conditions, there is often a start-up protection relay located there, but in some designs the thermostat is moved back for ease of maintenance without violating the seal of the chambers.
To check this area, you need to move the refrigerator away from the wall and remove the metal cover of the compressor compartment. Carefully inspect the area around the compressor and condenser grille. If the thermostat is located there, you will see its black or white plastic housing with a suitable tube going inside the body of the refrigerator.
However, in 95% of cases in household refrigerators Beko for the last 15 years, the thermostat is located inside the refrigerator compartment. Searching outside makes sense only if internal disassembly does not produce results, and the model belongs to rare or specific industrial series.
| System type | Probable location | Sensor type | Complexity access |
|---|---|---|---|
| Crying evaporator | Inside the chamber, under the lamp shade | Mechanical (TAM, K59) | Low |
| No Frost (Refrigeration compartment) | Behind the rear wall of the chamber | Electronic (NTC) | Medium |
| No Frost (Freezer compartment) | On the evaporator, behind the panel | Electronic (NTC) | High |
| Combined (old) | Outside, near the compressor | Mechanical | Low |
When working in the compressor compartment, be careful: there are high-voltage live parts there. Even when the appliance is unplugged from the socket, capacitors can retain a charge, and careless movement can damage the thin tubes of the circuit.
Removing and checking the serviceability of the thermostat
After you have determined where it is thermostat in your refrigerator Beko, and got access to it, it is necessary to carry out diagnostics. A visual inspection may reveal melted contacts or mechanical damage to the case, but an accurate diagnosis requires a multimeter. Mechanical thermostats are checked for “ringing” of the circuit in a cold and warm state.
To check a mechanical thermostat, disconnect it from the wires (after photographing the connection diagram first!). Switch the multimeter to resistance measurement mode. Immerse the thermostat sensing bulb (end of the capillary tube) in a container of cold water with ice for a few minutes. In good condition, when cooling, the contacts should close (or open, depending on the type), and the device will show one or zero.
☑️ Checking the thermostat
Electronic sensors Beko are checked by measuring their resistance at different temperatures. Normal resistance at room temperature (about 20-25°C) is usually 10-12 kohms (for 10kohm sensors) or 5-6 kohms (for 5kohm sensors). When heating or cooling, the resistance should change smoothly. An abrupt change or open circuit indicates a malfunction.
⚠️ Attention: Never check the functionality of the thermostat or sensor while it is connected to the control board or is under voltage. This is guaranteed to lead to the burning of the multimeter or the refrigerator control board itself.
If the test shows a malfunction, the element must be replaced. For mechanical thermostats, it is important to select an analogue with identical parameters (capillary tube length, temperature range, type of mounting). Installing the wrong thermostat may result in the refrigerator not working correctly.
Nuances of replacing and setting up a new regulator
Replacing the thermostat in the refrigerator Beko — this is not just a mechanical swap operation. After installing a new part, especially a mechanical one, it takes time for the system to stabilize. The capillary tube must be in the correct position in the evaporator, otherwise the temperature reading will be distorted. Often the tube needs to be bent in a certain way so that it follows the contours of the standard location.
In models with electronic control, after replacing the sensor, it may be necessary to reset errors in the control board memory. Without this, the refrigerator may continue to “think” that the sensor is faulty and will not start the compressor or fan. Reset is usually performed by long-holding certain buttons on the control panel, the combination of which depends on the specific series. Beko.
How to check the tightness after replacement?
After replacing the thermostat, if you removed the door seals or worked on the tubes going outside, be sure to check the tightness. Apply soapy water to the joints and turn on the refrigerator. The appearance of bubbles will indicate a freon leak, which requires an immediate call to a technician with a vacuum pump and sealing.
It is also worth paying attention to the length of the capillary tube. If the new part has a longer tube, its excess should not be bitten off or sharply bent at an angle of 90 degrees - this will pinch the channel and damage the thermostat. The tube must be carefully twisted into a ring with a diameter of at least 5 cm and placed in free space outside the chamber or in a special channel.
- 📏 The length of the capillary tube must correspond to the original with an error of no more than 10-15 cm, otherwise the calibration will be lost.
- 🔩 The thermostat mounting screws must be tightened tightly, but without fanaticism, so as not to damage the plastic case.
- 🧊 After replacement, let the refrigerator operate for 2-3 hours without loading food so that it returns to normal.
Do not forget that electronic thermistors Beko are very sensitive to static electricity. When working with them, it is recommended to use an antistatic wrist strap or at least touch a grounded metal object before touching the sensor contacts.
Common mistakes during self-repair
One of the most common mistakes when finding and replacing a thermostat c Beko is ignoring the wiring condition. In the rush to find a faulty part, amateur craftsmen often forget to check the integrity of the wires going to it. An oxidized contact or a frayed wire can give the same symptoms as a breakdown of the thermostat itself. Another mistake is using universal thermostats without resetting. Universal models (for example, the TAM series) often have an adjusting screw under the seal, which must be turned to fit a specific refrigerator. If this is not done, the unit will either freeze to a “stone” or not gain cold. thermostat.
Another mistake is using universal thermostats without resetting. Universal models (for example, the TAM series) often have an adjusting screw under the seal, which must be turned to fit a specific refrigerator. If this is not done, the unit will either freeze to a rock or not gain cold.
In addition, many forget about lubrication of seals and proper assembly of components No Frost. If, after replacing the sensor, you have not screwed the back wall tightly together, warm, humid air will enter the chamber, which will lead to rapid accumulation of ice and false temperature readings.
Always check adjacent systems. If the thermostat is working but the refrigerator isn't running, the problem could be the compressor, the relay, or even the wiring to the outlet. An integrated approach to diagnostics will save you money on buying unnecessary spare parts.
FAQ: Frequently Asked Questions
Is it possible to temporarily close the thermostat contacts to make the refrigerator work?
Technically, you can close the contacts, and the compressor will start in continuous operation mode. However, this will cause the refrigerator to freeze indefinitely until you manually turn it off. This is only permissible as a short-term measure to defrost or check the compressor, but the unit cannot be operated in this mode - the food will freeze, and the compressor may burn out from overheating.
Why does the refrigerator hum louder after replacing the thermostat?
An increase in the hum may be due to several factors: vibration of the new thermostat tube against the walls of the chamber, improper fastening of the unit itself (resonates with the housing) or changing the operating mode of the compressor if the new thermostat has different characteristics. Check whether the capillary tube is touching metal parts.
How to understand that the thermostat is stuck without disassembling the refrigerator?
Indirect sign - the refrigerator works non-stop (the compressor hums constantly), but the temperature in the chamber does not drop below +10...+15 degrees, or, conversely, the food in the upper part of the chamber turns into ice, although the regulator is unscrewed to a minimum. There may also be a lack of a characteristic shutdown click.
Where to buy an original thermostat for Beko?
Original spare parts Beko are best ordered from authorized service centers or specialized spare parts stores for household appliances, indicating the exact model of your refrigerator (E-NR code). Chinese analogues are cheaper, but their service life and calibration accuracy are often inferior to the originals.
Does placing the refrigerator near the battery affect the operation of the thermostat?
Yes, it does critically. If the refrigerator Beko standing close to the room or in direct sunlight, the thermostat (especially if it is located at the top of the chamber) will receive false data about the high temperature and cause the compressor to wear out. This leads to premature failure of both the thermostat and the motor.
