Refrigeration equipment of the brand Stinol, in particular model 107, has established itself as reliable equipment that can serve for decades. However, like any mechanical or electromechanical unit, it requires periodic adjustment to ensure proper storage of products. Many owners are faced with a situation when the chamber becomes too cold or, conversely, not cool enough, and wonder about the correct adjustment.
Correct setting up a thermostat is not just a matter of comfort, but also a necessity for maintaining food freshness and saving energy. Incorrectly set parameters can lead to freezing of vegetables, spoilage of dairy products or excessive load on the compressor. In this article we will analyze in detail the design of the control system, calibration methods and typical user errors.
Before taking active steps, you need to understand the operating principle of your device. The model Stinol 107 is usually equipped with a mechanical control system, which, despite its simplicity, requires careful and careful handling. Understanding the physical processes occurring inside the chamber will help you avoid common mistakes during operation.
The principle of operation of the Stinol 107 thermostat
The main element responsible for maintaining the climate inside the refrigeration chamber is thermostat. Model 107 uses a capillary thermostat that responds to changes in the temperature of a sensing element located inside the chamber. When the temperature rises above a set threshold, the contacts close, starting the compressor.
The cooling process continues until the air in the chamber cools down to the set value. The thermostat then opens the circuit and the engine stops. It is important to understand that the regulator knob does not directly control the compressor power, it only sets temperature threshold shutdowns.
Mechanical control systems, unlike electronic boards, do not have a digital display. This means that you cannot set the exact value in degrees Celsius. The adjustment is made empirically by turning the handle to a certain position, which corresponds to a certain temperature range.
⚠️ Attention: The mechanical thermostat has inertia. Changing the position of the handle does not immediately change the temperature inside the chamber. To stabilize the mode, it may take from 4 to 8 hours of operation.
Some modifications may be equipped with additional sensors, but the basic logic of operation remains the same: the more the knob is turned clockwise, the lower the temperature inside should be. However, scale calibration may differ depending on the specific instance and year of manufacture.
Location and description of controls
In refrigerators Stinol 107 the temperature regulator is most often located inside the refrigerator compartment. The standard location is the upper right corner, under or next to the lampshade. This is a classic solution for equipment of this class, allowing the sensor to correctly read the air temperature.
The regulator knob itself is a rotary mechanism with a printed scale. Typically the scale is marked with numbers from 0 to 7 or from Min to Max. The number 0 means a complete shutdown of the voltage supply to the compressor, and the maximum value corresponds to the strongest cooling.
In some versions, a mode switch may be located next to the main handle "Super Freeze" or similar functionality for the freezer, if it has separate controls. It is important not to confuse these elements so as not to upset the balance of the entire system.
What to do if the handle scrolls freely?
If the regulator handle scrolls without resistance or clicks, this may indicate a breakdown of the internal thermostat mechanism or the handle jumping off stock In the first case, replacement of the part is required, in the second - careful installation in place.
Step-by-step instructions for setting the temperature
The adjustment process requires a consistent approach and patience. You should not expect instant results, since the refrigeration cycle has its own inertia. Before starting any manipulations, make sure that the refrigerator is connected to the network and is operating normally.
First, determine the current problem: are the foods freezing at the back wall or, conversely, is the milk turning sour quickly? Based on this, decide on the direction of rotation of the handle. To increase the cold, turn the knob clockwise (towards large numbers), to weaken it - counterclockwise.
☑️ Setting algorithm
The optimal starting position for most models is considered to be 3 or 4 on the scale. This provision provides a balance between power consumption and storage quality. If, after installing the knob in this position, the temperature does not suit you, adjust it in steps of one division.
⚠️ Attention: Do not try to turn the regulator knob with force if it rests against the limiter. The mechanical stop is designed to protect the inside of the thermostat from damage. Forced rotation can lead to shaft breakage.
After each adjustment, it is necessary to give the system time to enter the new operating mode. The compressor must run a full cycle, including standstill time. Only after this can you objectively evaluate the effectiveness of the adjustment.
Deciphering the modes and adjustment scale
Users often mistakenly believe that the numbers on the scale correspond to degrees Celsius. This is wrong. The numbers indicate conventional cooling power levels. Understanding this difference helps to avoid confusion during operation Stinol 107.
Let's consider the approximate dependence of the handle position on the temperature inside the main chamber:
| Handle position | Operating mode | Approximate t° in the chamber | Recommendation |
|---|---|---|---|
| 0 | Off | +18...+20°C | Defrost or long shutdown |
| 1-2 | Minimum | +6...+8°C | Summer, small amount of food |
| 3-4 | Normal | +3...+5°C | Standard mode for most products |
| 5-6 | Strong | +1...+2°C | Large load, hot weather |
| 7 (Max) | Maximum | 0...+1°C | Short-term use, risk of icing |
Mode "Maximum" is not intended for continuous operation. Leaving the handle in the extreme position for a long time leads to the formation of a “snow coat” on the evaporator and increases the load on the engine. Use this mode only for quickly cooling large quantities of warm food.
Typical errors in adjustment and their consequences
One of the most common mistakes is trying to set the minimum temperature immediately after loading a large volume of products. This causes the compressor to run continuously, which can lead to overheating and failure. Load products gradually.
Another mistake is ignoring seasonality. In summer, when the ambient temperature in the kitchen is high, the refrigerator takes longer to cool down. In winter, on the contrary, there is less heat loss. Users who do not take this into account often hold the regulator in the wrong position.
Frequent opening of the door also disrupts the settings. If you constantly leave the door open while cooking, no amount of thermostat adjustment will help maintain a stable climate. In such cases, the control system will constantly “drive” the cold, trying to compensate for losses.
⚠️ Attention: Adjusting the temperature will not correct problems such as a freon leak, a loose door seal, or a compressor malfunction. If the refrigerator stops freezing even at maximum, check the technical condition.
It is also important to remember the location of the products. If you fill the chamber completely, blocking the access of cold air to the thermostat sensor, the readings will be incorrect. The compressor may turn off prematurely while the food has not yet cooled down.
Diagnostics of problems: when you need to replace the thermostat
There are situations when rotating the regulator knob does not give any result. The refrigerator either does not turn on at all or works continuously, regardless of the position of the switch. These are sure signs of a malfunction of the thermostat itself. If the compressor hums but does not start, or starts for a few seconds and stalls, the problem may not be in the settings, but in the starting relay or the engine itself. However, if the refrigerator simply does not respond to turns of the handle, most likely the contacts inside the thermostat are stuck or oxidized. thermostat.

Replacing the thermostat in the model Stinol 107 is a procedure accessible to a person with minimal repair skills. It requires disconnecting the device from the network, removing the handle, decorative panel and the control unit itself. The new sensor must have identical parameters and the length of the capillary tube.
Readjustment will be required after replacement. The factory parameters of a new thermostat may differ from a worn-out old one, so the adjustment procedure will have to be repeated, starting from average values.
The influence of external factors on the temperature regime
Do not forget that the operation of the refrigerator is affected not only by the position of the handle, but also by environmental conditions. Stinol 107 designed to operate in a certain climate class, usually this is SN or N. Exceeding the room temperature above +32°C may make it impossible to achieve low temperatures even at maximum.
Location of the refrigerator near heat sources (radiators, stoves, direct sunlight) causes the cooling system to work under overload. In such conditions, even correct adjustment of the thermostat will not save the situation. It is necessary to provide a gap between the back wall and the wall for ventilation.
The voltage in the electrical network also plays a role. With strong surges or chronically low voltage, the compressor may not develop the required power, which will lead to an increase in the temperature in the chamber. In such cases, it is recommended to use a voltage stabilizer.
Why does ice freeze in the Stinol 107 refrigerator, even if the temperature is set correctly?
Ice formation can be caused by several reasons: a loose door, a damaged seal, frequent opening of the chamber or a malfunction of the defrost system (if the model is No Frost). Ice can also appear when storing unburied liquid food.
Is it possible to install an electronic thermostat instead of a mechanical one in Stinol 107?
Theoretically, this is possible, but it requires serious modification of the design, laying new wires and installing sensors. Economically and technically this is not feasible for the old model. It is easier and more reliable to replace the mechanical thermostat with an original analogue.
How often do you need to defrost the Stinol 107 refrigerator?
Model 107 refers to a drip-type defrosting system (crying evaporator). Complete defrosting is required 1-2 times a year for hygienic cleaning and removal of ice crust if it appears. In normal mode, the system defrosts automatically with each compressor stop cycle.
What does the click inside the refrigerator mean after adjustment?
The click is the sound of the thermostat contacts opening or closing. This is normal operating sound. If the clicks occur too often (every few minutes), this may indicate a malfunction of the thermostat or a refrigerant leak.
