Modern household appliances require careful attention to the settings, and Italian technology Stinol is no exception. Correctly set temperature is the key to long service life of the products and proper operation of the compressor. Many owners encounter difficulties during the initial setup or after defrosting, not knowing how to interpret the regulator readings.
In this article we will analyze in detail the mechanics of the operation of thermostats located inside and outside the chamber. You will learn why the numbers on the scale do not always correspond to degrees Celsius and how to avoid common mistakes that lead to food spoilage or icing of the evaporator.
Understanding the principles air circulation in your specific model will help create ideal storage conditions. Regardless of whether you have a two-chamber model or a monoblock, the basic principles of setting remain similar, but have their own nuances.
The principle of operation of the temperature controller
Most models Stinol use a mechanical or electronic thermostat. The mechanical version is a rotary knob on which divisions are marked. It is important to understand that these divisions are not degrees, but conventional units of cooling power.
The higher the numerical value selected on the scale, the the compressor works more intensely. If you turn the knob to the maximum, the refrigerator will strive to reach the lowest possible temperature, which can lead to the freezing of vegetables in the main chamber. Conversely, the minimum value causes the unit to operate in a gentle mode.
⚠️ Attention: A sudden change in the position of the regulator from minimum to maximum can cause stress for the compressor. Change the settings smoothly, pausing several hours between switches.
Electronic control systems found in more modern lines allow you to set precise values in degrees Celsius. Here the principle is the opposite: you see the actual temperature and adjust it to the desired value. Such systems are often equipped digital sensorsthat respond to the slightest changes in thermal conditions.
You should not ignore the inertia of the system. After turning the knob or changing the number on the display, the refrigerator requires time - from 2 to 12 hours - to stabilize the climate inside the chambers. It is pointless to immediately evaluate the result.
Setting a mechanical thermostat
Classic models Stinol are equipped with a regulator located inside the refrigerator compartment, usually in the upper left or right corner. The scale may be labeled 1 to 5, 1 to 7, or even Min to Max. The manufacturer's standard recommendation is to set the switch to the middle position.
If you notice that the food in the main chamber begins to freeze, and a thick ice crust forms on the back wall, you need to reduce the power. To do this, turn the knob towards lower values. If the milk sours quickly and the inside is too warm, the regulator is shifted towards larger numbers.
Particular attention should be paid to the position thermostat depending on the season. In summer, when the room is hot, you may need a little more power than in winter. However, if the refrigerator is located near a radiator or in the sun, even the maximum setting may not cope with the load.
Some models have a combined regulator that controls both the refrigerator and freezer compartments simultaneously. In such cases, changing the setting affects both compartments, which requires more careful monitoring of the condition of the products in each zone.
Adjustment in models with No Frost
System No Frost (or “No Frost”) radically changes the approach to cooling. Here, cold air is forced to circulate through the chambers through special channels. In such models Stinol the regulator is often located on the outer panel or located in the upper part of the inner wall.
The main feature of the setting is the need to take into account the operation of the fans. If you set the temperature too low, the system may not have time to remove moisture, and ice will still appear on the food, although there will be no classic “snow” on the walls. The optimal range is considered to be one in which the compressor operates cyclically and not continuously.
In two-chamber models with one compressor and system No Frost there is often a temperature dependence between the compartments. By increasing the power in the freezer, you can inadvertently (unintentionally) overcool the main compartment. Therefore, balancing takes more time.
☑️ Checking the operation of No Frost
It is worth noting that in systems with full No Frost temperature sensors are located in the evaporator area, and not in the chamber itself. Therefore, the actual temperature of the products may differ from what the sensor shows if the chamber is filled to capacity and the circulation is disrupted.
Freezing and super-cooling modes
For quick freezing of large quantities of fresh food in refrigerators Stinol a special mode is provided, often designated as Super Freeze or snowflake. Activating this function causes the compressor to run non-stop, ignoring the standard thermostat settings.
This mode should be used with caution. If you forget to turn it off, the temperature in the freezer may drop to critical values, and everything in the refrigerator compartment will freeze. In mechanical models, this mode is often provided with a separate red button or the extreme position of the regulator.
After loading fresh products and their complete freezing (usually after 24 hours), the mode must be turned off. The device will automatically return to the previously set operating parameters. This allows you to save energy and engine life.
⚠️ Attention: Long-term operation in super-freezing mode (more than 3 days) can lead to failure of the door seals due to drying out of the rubber and excessive freezing.
In some advanced models there is also a “Vacation” mode or Holiday. It raises the temperature in the refrigerator compartment to +15°C (to prevent mold from growing), but keeps it frozen in the freezer. This is an ideal option for long-term absence of owners.
Table of optimal temperature conditions
To preserve the taste and usefulness of various categories of products, certain temperature ranges must be observed. Below is a reference table that will help you navigate the settings of your Stinol.
| Product type | Recommended temperature | Shelf life (approximate) | Zone in the refrigerator |
|---|---|---|---|
| Fresh meat, fish | from 0°C to +2°C | 1-3 days | Bottom shelf (freshness zone) |
| Dairy products | from +2°C to +4°C | 3-7 days | Middle shelves, not at the back wall |
| Vegetables and fruits | from +4°C to +8°C | 3-10 days | Bottom drawers (vegetable storage) |
| Ready meals | from +2°C to +5°C | 1-2 days | Top shelves |
| Frozen food | below -18°C | up to 12 months | Freezer compartment |
Please note that the temperature on different shelves of the same refrigerator may differ by several degrees. It is always warmer on the top shelf, and colder above the vegetable drawers. Place products according to this heat map.
If your refrigerator is equipped with dynamic cooling, temperature changes are minimal. In static models (drip system), the difference can be significant, so control over the placement of products is critical.
Why can’t you put hot food in the refrigerator?
Putting hot food causes a sharp jump in temperature, causing the compressor to work harder. In addition, condensation from a hot product quickly turns into an ice crust on the evaporator, worsening heat transfer.
Diagnostics of temperature problems
If you have set the settings according to the instructions, but the temperature does not meet expectations, the problem may not be with the regulator. There are a number of signs indicating a malfunction thermostat or a refrigerant leak.
For example, if the compressor works almost non-stop, and the chamber is still warm, or, conversely, it is silent, and ice has already formed inside - this is a cause for concern. It is also worth checking the tightness of the door.
A common reason for the temperature to “run away” is a damaged door seal. Warm, moist air enters the chamber through micro-slits, which the cooling system does not have time to cool. In this case, no resetting of the regulator will help.
⚠️ Attention: If you hear gurgling or hissing, but the compressor does not start for a long time, the capillary tube may be clogged or there is a freon leak. A call to the technician is required.
For accurate diagnosis, it is recommended to use an external thermometer placed in a glass of water. Place it on the middle shelf for a day. The readings of such a thermometer will be much more accurate than built-in sensors or subjective sensations.
Frequently asked questions (FAQ)
Why on the back wall Is ice forming in the Stinol refrigerator?
In models with a drip system, this is a normal process. During compressor operation, moisture freezes on the evaporator (rear wall). When the compressor turns off, the ice melts and flows into the drain hole. If the ice does not melt, check whether you have set the temperature too low, or whether the drainage is clogged.
Which position of the regulator should you choose in the summer?
In the summer, when the ambient temperature in the room is high, it is more difficult for the refrigerator to give off heat. It is recommended not to set the regulator to minimum, as the compressor may not be able to cope. It is optimal to leave the average value or slightly increase the cooling, but make sure that the food in the main chamber does not freeze.
What to do if the freezer is -25°C, but you need -18°C?
You need to turn the thermostat knob towards lower values (for example, from 5 to 3 or 4). Remember about inertia: changes will appear only after 6-10 hours. Do not try to adjust the setting every half hour.
Is it possible to completely turn off the freezer?
In most mechanical models Stinol it is impossible to turn off the freezer separately, since the refrigerant circulates through both circuits. However, some electronic models have a function to turn off one of the circuits. Check the instructions for your specific modification.
Does the amount of food affect the temperature setting?
Yes, an empty refrigerator cools faster, but holds the temperature worse when the door is opened. A full refrigerator is more stable, but takes longer to initially cool down. When fully loaded, a temporary increase in operating mode may be required.
