Modern life cannot be imagined without reliable refrigeration equipment, which preserves food freshness and ensures food safety. However, even high-quality equipment, such as Stinolrequires the correct approach to operation to maintain an optimal microclimate inside the chambers. Many users are faced with a situation where products begin to deteriorate faster than usual or, conversely, freeze, which indicates incorrectly set cooling parameters.
Adjusting the temperature is not just a mechanical action, but setting the system to your specific needs and environmental conditions. Depending on the model, be it a classic two-chamber unit or a modern No Frost, the algorithm of actions may vary significantly. Understanding the operating principles of the thermostat and sensors will allow you to avoid common mistakes and extend the life of the compressor.
In this guide we will look in detail at how to properly configure temperature regime in various models of Stinol refrigerators. We will look at the features of mechanical and electronic control systems, and also give practical advice on calibration. Proper adjustment will help you save energy and preserve the taste of products.
Principles of operation of the thermostat in Stinol models
The basis of the cooling system in most classic models of refrigerators Stinol is a mechanical thermostat. This device is a sensor that responds to changes in temperature inside the refrigerator compartment and opens or closes the electrical circuit of the compressor. When the air inside the chamber heats up above a set value, the contacts close, starting the motor, and when the desired cold is reached, they open, stopping the cycle.
It is important to understand that the regulator knob that you see on the panel does not have a scale in degrees Celsius. The numbers 1 to 5 (or Min to Max) indicate the degree of cooling intensity, not a specific temperature. The position thermostat affects how long the compressor will operate in each cycle. The higher the number, the lower the temperature inside the chamber will drop before stopping the engine.
⚠️ Attention: A sudden movement of the regulator knob from minimum to maximum can lead to water hammer in the refrigerant system. Switch modes smoothly, pausing for several minutes between changes.
In models with a system No Frost or “complete No Frost”, the operating principle is complemented by the operation of fans and a defrost system. Here the thermostat controls the temperature of the evaporator or air in the chamber, but the distribution of cold is forced. This provides more uniform cooling, but requires precise adjustment so as not to dry out the food.

The mechanical regulator is adjusted by turning the handle. It is usually located inside the refrigerator compartment on the right wall or above the door. The numbers on the scale mean the following: one - minimum cooling (temperature higher), five - maximum (temperature lower). For normal food storage mode, it is recommended to set the handle to position 2.5 or 3.
If you notice that ice crustis forming on the back wall of the refrigerator compartment, and the products in the drawers are freezing, it means that the cooling power is too high. In this case, you need to smoothly turn the knob towards decreasing the value (towards one). Conversely, if the food spoils quickly, and the compressor works rarely and turns on for a short time, you should increase the value.
☑️ Checking the mechanical settings
Adjusting electronic control systems
More modern models Stinol (for example, series with the index RF or NF) are equipped with an electronic control unit that allows you to set the temperature with an accuracy of a degree. The control panel in such models is usually located on the outside of the door or inside the chamber on the top wall. Here you see digital indicators displaying the current temperature in the refrigerator and freezer compartments.
To change parameters, you must use the Mode or Temp. Pressing the button causes the selected camera's indicator to flash, after which you can use the arrow or plus/minus buttons to change the value. The standard recommendation for the refrigerator compartment is +4°C, and for the freezer - -18°C. These values are considered optimal for long-term storage of most products.
⚠️ Attention: On electronic models, changing the setting does not take effect instantly. The compressor and control system can begin to adjust the mode within 1-2 hours. Do not try to change the settings again during this period.
Particular attention should be paid to the function "Super Freeze" (Super Freeze) or “Quick Cooling”. This mode forcibly turns on the compressor for long periods of time, ignoring standard shutdown cycles. It should only be used when loading a large amount of fresh food, being sure to turn off the function after achieving the result (usually after 24 hours or automatically) to prevent overloading the system.
What to do if the electronics do not respond?
If the control panel does not respond to presses, it may be The child lock has worked. Try holding down a combination of buttons (often two buttons at the same time) for 3-5 seconds. The exact combination for your model can be found in the technical data sheet of the device.
The influence of seasonality and load on temperature
The environment has a direct impact on the operation of refrigeration equipment. In summer, when the room temperature rises, heat exchange is disrupted and the compressor takes longer to remove heat. On hot days, you may need to slightly increase the cooling power (shifting the regulator towards higher numbers) to compensate for the heating of the case.
In winter, the situation is the opposite: in a cool room, the refrigerator works more efficiently. However, if the room temperature drops below +16°C, models with a single compressor and a mechanical thermostat may have problems starting, as the sensor in the refrigerator compartment will not detect sufficient heat to turn on the motor. In such cases, it is recommended to use the “Winter” mode (if available) or move the unit to a warmer place.
The degree of loading of the chambers also affects the temperature regime. A fully filled refrigerator stays cold longer, but takes longer to initially cool down. An empty unit reacts faster to opening the door, losing cold. The optimal load is about 70-80% of the total volume, which ensures proper circulation of air flow.
Typical problems and solutions
Even with proper settings, users may encounter situations where the actual temperature does not meet expectations. Often the cause is not a malfunction, but a banal violation of operating rules. For example, a door that is not tightly closed or a damaged seal leads to a constant flow of warm air, which is why the compressor works continuously, but does not provide the required cold.
Another common problem is the formation of an excessive “fur coat” on the evaporator in models with a drip system. If the drainage hole is clogged with food or ice, the moisture does not leave, freezes and blocks the access of cold air. In this case, adjusting the thermostat will not help - defrosting and cleaning the drainage is necessary.
| Symptom | Possible cause | Solution |
|---|---|---|
| Food in the refrigerator freezes | Thermostat is set to maximum (4-5) | Reduce the value to 2-3 |
| Food spoils, heat inside | Ventilation holes are clogged | Release air access |
| The compressor hums, but does not start | Power surge or relay malfunction | Check the socket, call a technician |
| Ice on the back wall | Operating mode too intensive | Reduce cooling power |
If you have tried all adjustment methods, checked the seals and made sure the electrical network is working, but the temperature still does not hold, there may be a refrigerant leak or the thermostat itself has failed. In such cases, independent repair can be dangerous and ineffective.
FAQ: Frequently asked questions
Why is the temperature in the Stinol freezer -24°C, although it is -18°C?
This may occur due to the “Super Freeze” mode being turned on or a sensor malfunction. Also check if the air supply channel from the freezer to the refrigerator compartment is clogged with ice.
Is it possible to change the temperature settings while the refrigerator is running?
Yes, the mechanical thermostat can be turned in any direction during operation. Electronic settings also change on the fly, but the effect will become noticeable after a while.
What temperature is considered normal for storing vegetables?
The optimal zone for vegetables and fruits is a temperature from +4°C to +7°C. Usually these are lower shelves or special drawers where the cold is distributed less intensively.
Why does the refrigerator take a long time to reach the temperature after defrosting?
After complete defrosting, the system takes time (from 2 to 6 hours) to reach operating mode. Do not load food into warm chambers so as not to overload the compressor.
