Two-chamber refrigerators of the brand Stinol have been popular for many years due to their reliability and simplicity of design. However, owners are often faced with the question of how to correctly set the temperature so that the food remains fresh for a long time and frost does not form on the walls. Understanding the operating principles of a thermostat is the first step to proper operation of household appliances.
Incorrectly set parameters can lead to food spoilage or excessive energy consumption. In this article we will analyze in detail the mechanics of adjustment, features of operation in different conditions and answer frequently asked questions from users.
The principle of operation of the Stinol thermostat
Most models of two-chamber refrigerators Stinol use a mechanical thermostat. This device automatically maintains the set temperature inside the chambers by periodically starting and stopping the compressor. Adjustment is carried out by turning the knob, usually located inside the refrigerator compartment or on the top panel of the case.
It is important to understand that the scale on the regulator does not display degrees Celsius. Numbers from 1 to 5 (or from Min to Max) indicate cooling intensity. The higher the number you choose, the colder it will be inside. Setting the value to the maximum causes the compressor to work almost without interruption, which can lead to freezing of the evaporator.
The thermostat reads the air temperature in the refrigeration chamber and, having reached the specified threshold, opens the electrical circuit. In the freezer compartment, the temperature drops along with the main chamber, since the refrigerant circulates through a single circuit in classic models. Therefore, changing the setting in one compartment affects the operation of the entire system.
⚠️ Attention: Do not try to forcefully turn the control knob beyond the scale. The mechanical limiter was not created by chance, and excessive force can break the plastic rod inside the thermostat housing.
Deciphering the adjustment scale
Users often mistakenly believe that the number on the regulator corresponds to the temperature in degrees. In fact, these are conditional divisions of power. Refrigerators Stinol are characterized by the following logic of the regulator:
- 🌡️ Position 1 (or Min): Minimum cooling. The temperature in the refrigerator compartment will be closer to +8...+10°C. Suitable for storing vegetables that are afraid of the cold, or when the refrigerator is half empty.
- ❄️ Position 3 (middle): Optimal mode for everyday use. Provides standard +4...+5°C in the refrigerator and about -18°C in the freezer.
- 🧊 Position 5 (or Max): Maximum cooling. The compressor operates in high load mode. Used for quick freezing of large volumes of food or in extreme heat in the room.
The choice of the correct position of the handle depends on many factors: the amount of food, the ambient temperature in the kitchen and the frequency of door opening. The factory setting of the Stinol thermostat usually corresponds to position "3" or "4", and in 90% of cases it is not necessary to change it.
If you notice that the products in the refrigerator compartment begin to freeze at the back wall, it means that the cooling power is too high for the current amount of loading. In this case, you should switch the regulator to a division closer to the minimum.
Optimal temperature conditions
For long-term storage of products, it is necessary to maintain a stable microclimate. In two-chamber models Stinol without the No Frost system (with a drip defrosting system), the temperature distribution is uneven. It is coldest at the back wall and on the upper shelves, warmest on the door and in the lower drawers.
In the freezer, it is important to maintain the temperature no higher than -18°C. It is at these levels that most bacteria stop their activity, and vitamins in vegetables and meat are preserved for months. In the refrigerator compartment, the optimal range is considered to be from +2°C to +6°C.
Below is a table of the dependence of the recommended settings on external conditions:
| Operating conditions | Knob position | Expected t° in the fridge compartment | Compressor operating mode |
|---|---|---|---|
| Summer (hot in the kitchen) | 4 - 5 | +3...+4°C | Frequent switching on |
| Normal (room t°) | 3 | +4...+5°C | Normal cycle |
| Winter (cold indoors) | 2 - 3 | +5...+6°C | Rare switching on |
| Loading warm products | Temporarily at Max | Rapid reduction | Continuous operation |
It should be remembered that complete stabilization of the temperature after changing the setting does not occur instantly. The refrigeration unit requires from 4 to 6 hoursto enter a new operating mode. You should not turn the knob every half hour, trying to “guess” the ideal degree.
Instructions for setting the temperature
The process of setting the temperature in refrigerators Stinol is extremely simple and does not require special tools. However, for the system to operate correctly, it is important to follow the sequence of actions, especially if you are changing the settings for the first time or after defrosting.
First you need to free access to the thermostat. In classic models, it is located inside the refrigerator compartment, in the upper right corner, often hidden by a plastic cover or combined with a lampshade. In some modifications, the handle is placed on the external panel above the door.
☑️ Stinol setting algorithm
Next follow these steps:
- Turn the regulator knob to position
0orOffto turn off cooling for 5-10 minutes. This will allow the system to release residual pressure and relax the springs. - Set the handle to position
3. This is the basic setting for most situations. - If your refrigerator has a quick freeze button (usually red with an indicator), make sure it is off (the indicator is not lit), otherwise the compressor will not turn off.
- Leave the refrigerator operating in normal mode for a day without loading it completely with food.
After the device will work several cycles (turn on and off on its own), you can fine-tune it. If the food on the top shelf becomes covered with frost, reduce the power. If the milk turns sour quickly, add it.
⚠️ Attention: If you have just defrosted the refrigerator, do not immediately set the maximum power. Let the unit operate for 2-3 hours at the medium setting so that the refrigerant is evenly distributed throughout the system.
Features of operation in winter and summer
Seasonal fluctuations in room temperature directly affect the operation of the refrigerator Stinol. In summer, when the ambient temperature in the kitchen reaches +28...+30°C, heat exchange is difficult. The compressor takes more time to cool the chambers to the set values.
During hot periods, it is recommended to switch the regulator to higher values (4 or 5). This compensates for heat gain from the walls and frequent door openings. However, make sure that the refrigerator does not work continuously for hours - this can lead to overheating of the motor.
In winter, the situation is the opposite. If the room is cool (around +16...+18°C), the thermostat takes less time to reach the target temperature. Setting the regulator to maximum will lead to the fact that the food in the refrigerator compartment will freeze, and in the freezer, on the contrary, thawing may begin due to rare operating cycles (in single-circuit systems).
What is a climate class?
The climate class indicates the range of ambient temperatures at which the refrigerator is guaranteed to operate. For the SN (subnormal) model this is from +10°C to +32°C. If your kitchen is +10°C in winter, the refrigerator may stop turning off or not turn on at all, since the thermostat “thinks” it’s already cold.
It is important to consider the location of the refrigerator. If it is located next to a stove, a radiator, or in direct sun, even in winter it may require a more intense cooling mode. In such cases, additional thermal insulation of the side walls helps.
Typical errors during adjustment
Many users make mistakes when trying to “improve” the operation of the equipment, which ultimately leads to breakdowns. The most common of them is installing the regulator on Max immediately after turning on or loading a large amount of warm products.
This creates a colossal load on the compressor, which in conventional models Stinol does not have inverter control and operates either at 100% power or is turned off. Long-term operation at maximum capacity reduces engine life and can cause thermal breakdown.
Another mistake is ignoring the fullness of the chambers. An empty refrigerator cools down faster, but it also heats up instantly when the door is opened. A unit completely filled with food keeps the cold longer, but requires more time for initial cooling.
- 🚫 Error: Constantly turning the knob back and forth in search of the ideal.
- 🚫 Error: Setting the minimum temperature in the summer “to save electricity” (food will spoil).
- 🚫 Error: Ignoring ice. If the “coat” on the back wall is thicker than 5 mm, the cooling efficiency drops and the regulator makes the motor work longer.
When the help of a specialist is required
Self-adjusting the temperature is possible and safe, but there are situations when the problem lies not in the regulator, but in the malfunction of the components. If you have tried all the positions of the handle, but the situation does not change, the device may have failed.
An alarming signal is a situation when the refrigerator does not turn off at all, working around the clock, and the temperature in the chambers does not drop below +10°C. This may indicate a freon leak or loss of compressor performance.
A specialist’s help is also necessary if:
- The control knob rotates freely without feeling the resistance of the spring.
- The refrigerator does not turn on at all, even when the knob is moved to the Max position.
- A giant lump of ice forms on the back wall, but the food in the main compartment is warm.
⚠️ Attention: Replacing the thermostat requires partial disassembly of the housing and, often, release of the refrigerant. Do not attempt to replace this part yourself without knowledge of working with refrigeration equipment and a vacuum pump.
Why do vegetables freeze in the Stinol refrigerator?
This happens if the regulator is set to the maximum value (4-5) with a small load of products. Another reason could be that the vegetables are too close to the back wall where the evaporator is located. Try reducing the power to “2” or “3” and moving the food away from the wall.
How to understand that the thermostat is broken?
Main signs: the refrigerator does not respond to turns of the handle (the operating mode does not change), or the device operates continuously, without turning off even when the chambers are clearly overcooled. It is also possible that the refrigerator is silent even at maximum.
Is it possible to use the Stinol refrigerator on the balcony?
The manufacturer does not recommend operation at temperatures below +10°C (climate class SN). On an uninsulated balcony in winter, the oil in the compressor will thicken, which will lead to its breakdown at startup, and the thermostat may simply not turn on the unit.
Is it necessary to defrost the refrigerator when the season changes?
It is not necessary to specifically change the settings for the season, but complete defrosting (at least 1-2 times a year) is necessary to remove ice. Before defrosting, it is better to move the regulator to position "0", and after turning it on - immediately to the average value.
