Correctly setting the climate system in the refrigerator Ariston (formerly Indesit) is a critical condition for maintaining food freshness and energy savings. Many users mistakenly believe that the colder it is inside, the better, but excessive cooling leads to spoilage of vegetables and the formation of ice.
Modern models of refrigeration equipment from this brand are equipped with electronic or mechanical controls, and understanding the principles of their operation will help you avoid common mistakes. In this article we will look at what values are optimal for the main chamber, freezer compartment and freshness zone.
Optimal values for the refrigerator compartment
The main chamber is designed for storing products that do not require freezing, but need refrigeration. Gold standard for most food products, the range is considered to be from +3°C to +5°C. It is with these indicators that the growth of bacteria slows down, but the structure of the products is not disturbed.
If you have a model with a mechanical regulator, where the scale is indicated by numbers from 1 to 5 or from 1 to 7, Therefore, the position "5" or "7" corresponds to the lowest (cold) temperature inside the chamber.
In the summer, when the ambient temperature in the kitchen is high, the regulator should be set to medium values (usually 3 or 4) so that the compressor does not work non-stop. In winter, if the refrigerator is in an unheated room, the settings may require correction, but we will talk about this below.
⚠️ Attention: Setting the regulator to the maximum value (MIN or MAX) unnecessarily leads to freezing of the back wall and over-drying of food. Use maximum cooling only to quickly freeze fresh food.
Setting the freezer compartment
The freezer compartment requires lower temperatures to ensure long-term storage of supplies. The standard value for long-term storage is -18°C. At this temperature, products can be stored for up to a year without loss of taste.
Function Fast Freeze (quick freezing) allows you to temporarily lower the temperature to -24°C or lower. This is necessary when you load a large amount of warm or fresh food into the chamber so that it quickly passes through the crystallization zone.
You should not keep the fast freezing mode on all the time. This creates an excess load on compressor and leads to excessive consumption of electricity. After the food has frozen (usually after 24 hours), the function must be turned off.
- ❄️ For everyday storage, keep a stable -18°C.
- 🥩 When loading a large volume of meat, turn on Super Freeze for a day.
- 🔌 Do not forget to return the settings to standard mode after freezing.
Features of the freshness zone (Zero Zone)
In advanced models Ariston there is a separate compartment, often called the “Fresh Zone” or “0°C”. Here the temperature is maintained close to zero, but does not turn into freezing. This is an ideal place to store meat, fish, dairy products and herbs that you plan to cook in the coming days.
Control of this zone can be automatic or manual. On some models, you must manually switch the damper or activate a special mode on the control panel. The temperature here usually ranges from 0°C to +2°C.
Remember that it makes no sense to put products that have already been frozen in this compartment - they will not restore their properties. It is also not recommended to store vegetables with a high water content here, as they may freeze and lose their crunch.
Why do vegetables spoil in the freshness zone?
Some vegetables (cucumbers, tomatoes) do not tolerate temperatures close to 0°C. The middle shelves of the main chamber are better suited for them, where it is warmer (+4..+6°C).
Seasonal adjustment of settings
The external ambient temperature directly affects the operation of the refrigeration unit. In the summer, when the kitchen is hot, heat exchange is disrupted and the refrigerator takes longer to reach the set parameters. During this period, it is advisable to slightly increase the cooling.
In winter the situation is the opposite. If the refrigerator is in a cool kitchen, the compressor may turn on too rarely. For models with one compressor and mechanical control, there is a rule: in winter, switch the regulator to a “warmer” mode (lower number) to give the motor a chance to rest, or, conversely, to a “colder” mode so that it turns on more often, if the model requires it.
⚠️ Attention: Check the climate class in the instructions for your model. Ariston climate class. Operation at temperatures below +10°C or above +32°C may be prohibited by the manufacturer and will lead to breakdown.
☑️ Checking seasonal settings
Deciphering indicators and error codes
Electronic control panels of refrigerators Ariston equipped with a self-diagnosis system. If the temperature regime is violated or the sensors detect anomalies, warning symbols may light up on the display.
The most common is a flashing temperature indicator or the "Alarm" symbol. This is a signal that the inside of the chamber is warmer than it is set to. This happens immediately after the first turn on, after defrosting, or when the door is not tightly closed.
If the indicator is constantly on and the temperature does not drop even after several hours of operation, there may be a freon leak or the thermostat has failed. In this case, self-adjustment will not help.
| Indicator | Value | User action |
|---|---|---|
| Flashing temperature | Temperature is above normal | Check the tightness of the door closure |
| Alarm / Exclamation mark | Alarm signal | Press the reset button, check the products |
| Snowflake (flashing) | Quick freezing mode | Disable after 24 hours |
| Lock | Lock buttons | Hold the button for 3-5 seconds to unlock |
Frequent problems with temperature conditions
Even with the correct settings, users may encounter a situation where food freezes in one part of the chamber and spoils in another. Often the reason lies not in a malfunction, but in improper loading or positioning of the equipment.
If you notice ice on the back wall of the main chamber, this may be a sign of a system malfunction No Frost (if it is declared) or simply a consequence of frequent opening of the door when the humidity in the room is high. In models with a drip system ("crying wall"), periodic ice formation and drainage is a normal operating cycle.
Overloading the chamber with products also interferes with the circulation of cold air. The air should flow freely around the shelves. If you have covered the ventilation holes with bags or boxes, the temperature sensor will read incorrect data.
- 🌬️ Do not place hot food inside - this will confuse the sensors.
- 🚪 Check the door seal for cracks and dirt.
- 📏 Leave a gap of 5-10 cm between the back wall and the kitchen wall.
Why is it too cold in the Ariston refrigerator even at minimum?
If The regulator is turned to minimum (number 1), and the food freezes; most likely, the thermostat or temperature sensor has failed. It is “stuck” in the closed contact position and constantly sends a signal to the compressor to work. Part replacement required.
What temperature should I set in a single-compressor refrigerator in the summer?
In the summer, when the room is hot, single-compressor models experience increased load. It is recommended to set average values (3 out of 5). If this is not enough, you can add 0.5-1 division, but do not set it to maximum so that the compressor does not burn out from continuous operation.
What to do if the display shows an error and does not respond to buttons?
Try to perform a full system reset. To do this, disconnect the refrigerator from the power supply for 10-15 minutes. Then turn it on again. If the error (for example, flashing of all indicators) persists, diagnostics of the electronics is necessary at a service center.
Does the amount of food affect the temperature inside?
Yes, it does. An empty refrigerator changes temperature faster when the door is opened. A filled chamber (especially with bottles of water or frozen food) works as a cold accumulator and better maintains temperature conditions. However, you cannot fill the chamber to capacity - air circulation is needed.
Is it normal that the back wall is covered with ice?
For refrigerators with a system Direct Cool (drip) - this is normal. Moisture condenses on the cold back wall, freezes, and then when the compressor turns off, melts and flows into the drain. If food or side walls are covered with ice, this is a sign of a malfunction.
