Correct adjustment The temperature regime in refrigeration equipment is a key factor ensuring long-term preservation of the freshness of products and their taste. If configured incorrectly, you risk experiencing rapid spoilage of perishable food or, conversely, excessive energy consumption due to excessive cooling.
Refrigerators Ariston have earned a reputation as reliable equipment, but even the most advanced models require a competent approach to operation. Owners often wonder how to set the optimal values so that it is cold enough in the main chamber and food freezes evenly in the freezer.
In this guide we will analyze in detail all the nuances of setting different types of thermostats, consider the dependence of the microclimate inside the chambers on external factors and give specific recommendations for maintenance.
The principle of operation of the thermostat and types control
The basis of the cooling system is thermostat (thermostat), which automatically turns the compressor on and off depending on the temperature inside the refrigeration chamber. In models Ariston there are two main types of control: mechanical and electronic.
Mechanical regulators are a rotary dial or knob with digital symbols, usually located inside the refrigerator compartment. Here the numbers do not mean degrees Celsius, but indicate the cooling intensity: the higher the number, the colder.
Electronic control panels are usually located on the outer door and are equipped with a display. They allow you to set the exact temperature in degrees for each chamber separately. Setting accuracy in such models it is higher, which has a positive effect on energy consumption.
Setting the mechanical thermostat
In classic models Ariston adjustment is carried out by turning the round knob. The scale can have numbers from 1 to 7 or from Min to Max. It is important to understand that position “1” or “Min” corresponds to the warmest mode, and “7” or “Max” corresponds to maximum freezing.
For everyday use, it is recommended to set the knob to the middle position, usually the number “3” or “4”. This ensures a balance between food safety and compressor load. If you have loaded the chamber with a large amount of warm food, you can temporarily increase the power.
⚠️ Attention: Never immediately set the mechanical regulator to the maximum value (7 or Max) unless absolutely necessary. This will lead to the formation of an ice crust on the back wall and possible freezing of food.
After changing the position of the handle, you must wait several hours before drawing conclusions about the operation of the equipment. The system should stabilize, and the sensors should read new readings.
Adjusting electronic controls and display
Modern refrigerators Ariston with a system No Frost and electronic control allow you to set specific temperature values. To change parameters, you usually need to press and hold the button with the image of a thermometer or snowflake for 3-5 seconds.
After activating the setting mode, the numbers on the display will begin to flash. Using the "+" and "-" buttons or arrows, select the desired value. Confirmation of the selection often occurs automatically a few seconds after the last press or by pressing the mode button again.
Sequence of actions:1. Press the "Freezer" or "Fridge" button (camera selection).
2. Hold for 3 seconds until the blinking indicators appear.
3. Use the "+" or "-" buttons to change the value.
4. Wait until the blinking stops to save.
The function Super Freeze (Super Freeze) deserves special attention. When activated, the compressor operates continuously, ignoring the thermostat readings, in order to quickly freeze large volumes of food. Remember to turn off this mode manually if it does not have an automatic timer.
☑️ Checking the electronics settings
Optimal temperature conditions for different products
To ensure food safety, it is important to maintain a temperature in the refrigerator compartment in the range from +2°C to +6°C. In such conditions, the growth of bacteria slows down, but the food does not freeze.
In the freezer, the optimal value is -18°C or lower. At this temperature, products can be stored for months without losing their properties. However, for short-term storage (a week or two) -12°C is sufficient, which saves energy.
| Product type | Recommended zone | Optimal temperature | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and fish | Lower shelf, freshness zone | 0°C ... +2°C | 1-3 days |
| Dairy products | Middle shelves | +2°C ... +4°C | 3-7 days |
| Vegetables and fruits | Bottom drawers | +5°C ... +8°C | 3-10 days |
| Frozen semi-finished products | Freezer compartment | -18°C ... -24°C | 6-12 months |
It is worth considering that different zones inside the refrigerator have different temperatures. The back wall, where the cold air comes out, is always colder than the door. Place food taking into account this thermodynamics.
Why can't you put hot food in the refrigerator?
Placing hot food causes a sharp jump in temperature, which causes the compressor to wear out. In addition, the steam condenses and turns into ice, worsening heat transfer.
The influence of external factors and seasonal adjustment
The temperature in the room where the refrigerator is installed Aristondirectly affects its operation. In the summer, when the apartment is hot, the unit has to work harder to maintain the set parameters inside the chambers.
In winter, if the refrigerator is located in an unheated room or near a balcony door, problems may arise with starting the compressor or, conversely, with insufficient cooling of the freezer in single-compressor models. This is due to the peculiarities of the operation of refrigerant and the thermostat.
⚠️ Attention: Installing the refrigerator next to heating appliances, a stove or in direct sunlight is strictly not recommended. This leads to overheating of the condenser and failures in maintaining the temperature regime.
If you notice that in the summer the food began to thaw, and in the winter, on the contrary, to freeze in the refrigerator, make seasonal adjustments to the thermostat settings. Move the slider one notch towards more powerful cooling in summer and towards weaker cooling in winter.
Diagnostics of temperature problems
Sometimes even the correct setting does not produce results due to technical faults. The first sign of problems is the formation of a large “coat” of ice on the back wall or a complete lack of cold when the compressor is running.
A frequent cause of temperature violations is damage to the rubber seal on the door. If it does not fit tightly, warm air enters inside, and the refrigerator cannot reach the desired temperature, working non-stop.
- 🔍 Check the tightness of the door using a sheet of paper: clamp it in different places of the closed door, it should be pulled out with force.
- ❄️ Inspect evaporator for the presence of a thick layer of ice that may block air circulation.
- 🔌 Make sure that the ventilation holes inside the chamber are not blocked by food or packaging.
It is also worth checking the quantity of food. A crowded refrigerator or, conversely, an almost empty one (less than 10-15% of the volume) works less efficiently. Products serve as cold accumulators, stabilizing the temperature.
Prevention and care of the cooling system
To ensure that the temperature settings always work correctly, it is necessary to regularly service the equipment. Once every 6-12 months, it is recommended to completely defrost (if the model is not No Frost) and thoroughly wash the internal surfaces.
It is important to monitor the cleanliness of the condenser located on the back wall or in the base of the refrigerator. Dust and pet hair create an insulating layer, preventing heat dissipation, which causes the cooling system to work overload.
Remember to check the drainage hole to remove melt water. If it is clogged, water will begin to accumulate at the bottom of the refrigerator compartment, which can lead to increased humidity and disruption of the temperature balance.
What to do if after setting the temperature does not change?
If you changed the settings, more than 24 hours have passed, and the temperature inside the chambers does not correspond to the set values, the thermostat itself, the temperature sensor may have failed, or a leak has occurred. Freon. In this case, diagnostics by a service center specialist is necessary.
Can a thermometer be used for testing?
Yes, this is the best method of calibration. Place a regular household thermometer in a glass of water on the middle shelf of the refrigerator overnight. Compare the readings with the settings on the display or the expected range for a mechanical handle.
Does frequently opening the door affect the temperature?
Absolutely. Each opening of the door results in the loss of cold air and the entry of warm air. The compressor takes time to restore balance. Try not to keep the door open for more than 30-40 seconds.
Do you need to change the settings when the power goes out?
There is no need to specially change the settings, modern models Ariston retain memory. However, after turning on, do not immediately load the products, let the unit reach the temperature in an empty state for 2-3 hours.
