How to turn off the freezer in an Ariston refrigerator: a complete guide

Owners of refrigeration equipment Ariston often face the need to change the operating modes of the equipment in order to adapt it to the current needs of food storage. The question of how to turn off the freezer in an Ariston refrigerator becomes especially relevant during periods when it is necessary to expand the space of the main chamber or switch the unit to “vacation” mode. Correct setting allows you not only to optimize energy consumption, but also to extend the service life of the compressor.

It is worth noting right away that the technical possibility of completely shutting off the lower compartment depends on the specific model and type of cooling system. While in older single-compressor models this is almost impossible to do without intervention in the design, modern dual-circuit systems allow flexible temperature control. Understanding the operating principles of your refrigeration unit refrigeration unit will help you avoid mistakes and damage to products.

In this article we will analyze in detail the mechanical and electronic adjustment methods, and also explain why in some cases complete shutdown is impossible. You will learn about the nuances of the operation of thermostats and electronic control modules that control refrigerant circulation. This knowledge is necessary for every owner of equipment Aristonwho wants to properly operate household appliances.

Principles of operation of Ariston refrigerators and the possibility of insulating chambers

To understand whether it is possible to turn off the freezer, you need to understand in the cooling architecture of your model. Most refrigerators Ariston, especially those released in past decades, operate according to a scheme with one compressor and one cooling circuit. In such a system refrigerant passes sequentially through the evaporator of the freezer and the main compartment.

This means that it is physically impossible to stop cooling in one compartment without stopping the operation of the entire refrigerator. Thermostat in such models it is usually located in the main chamber or on a common wall, and it controls the activation of the compressor to maintain the temperature throughout the volume. An attempt to “turn off” the freezer in a single-circuit system will only lead to defrosting of all products.

The situation changes dramatically if you own a modern model with a No Frost or dual-circuit cooling system. Here, separate solenoid valves fans are responsible for the distribution of cold. The electronic control unit can independently regulate the supply of cold air or freon to different zones, which theoretically allows you to increase the temperature in the freezer to the values of the main chamber.

⚠️ Attention: In single-circuit models with mechanical control, an attempt to shut off the cold supply channels to the freezer on your own will lead to overheating of the compressor and its exit building. Do not interfere with the design without confirming the presence of two circuits.

You can determine the type of your system using the technical data sheet or model. If the name or characteristics indicate “Full No Frost” or “Dual Cooling”, the chances of successful software isolation of the cameras are high. In other cases, it will be more about switching to an economical mode, rather than a complete shutdown.

Mechanical control: working with thermostats

In models Ariston with mechanical control, adjustment is carried out using rotary knobs or buttons located inside the main chamber. These devices are nothing more than thermostatsthat open the electrical circuit when a predetermined temperature is reached. Typically, the scale has values ​​from 1 to 5 or from “Min” to “Max.”

To minimize the operation of the freezer compartment in such refrigerators, it is necessary to set the regulator to the minimum cooling position. However, as already mentioned, this will reduce the cold in the main compartment as well. Some users try to find a second regulator that could be responsible separately for the freezer, but in 90% of models Ariston with mechanics it simply does not exist.

There is also a “Super Freeze” mode, which is often indicated by a snowflake or a button with the corresponding symbol. Activation of this mode forces the compressor to work continuously, ignoring the thermostat readings. To turn off or reduce freezer activity, this mode must be turned off. If the button is lit or stuck, the compressor will not turn off, which will lead to deep freezing.

If your model is equipped with a separate switch for the freezer (which is rare, but found in some industrial or specific household series), the algorithm is simple: move the knob to the “0” or “Off” position. In this case, the power supply circuit of the compressor or valve responsible for the lower compartment is opened.

Electronic control and display panels

Modern refrigerators Ariston are equipped with electronic control modules with digital displays. This gives the user much more options for fine tuning. Here you can independently set the temperature for the upper and lower compartments. To enter the setup mode, you usually need to press and hold the setup button for 3-5 seconds.

In the settings menu, look for the section responsible for temperature mode. Using the "+" and "-" buttons you can increase the temperature in the freezer to the maximum possible value, for example up to -6°C or even up to +5°C in some models with the "Storage" function. When positive values ​​are reached, the freezer actually turns into an additional refrigeration compartment.

It is important to understand the difference between turning off the chamber and the “Vacation” mode. The Holiday Mode (Vacation) function usually turns off the main chamber, leaving the freezer to operate normally to preserve frozen food. You need the opposite situation, so the “Vacation” mode is not suitable in this case. You must manually reset the lower compartment settings.

If the error indicator lights up on the display or the temperature flashes, this may indicate that the set parameters cannot be achieved with the current load or system condition. In this case, electronic unit can ignore the command to increase the temperature if the sensors detect the risk of defrosting critical components.

Using the "Vacation" mode and saving energy

Many users mistakenly believe that the "Vacation" mode allows you to turn off the freezer. In fact, the logic behind the operation of refrigerators Ariston in this mode is aimed at preserving frozen food with minimal energy consumption while the main chamber is idle. Operating algorithm is to maintain a low temperature in the freezer and increase the temperature in the refrigerator compartment to 12-15°C to prevent the appearance of mold and odors.

However, in some new models with intelligent control (Smart Cooling), the user can customize the “Vacation” mode. In this case, through the menu you can select the “Refrigerator compartment only” option or a similar one, if such a function is provided by the manufacturer. This will allow you to disable active frost formation in the lower block.

If your goal is simply to save energy and not use the freezer as a cabinet, then switching to economy mode with an increase in temperature to -6°C will be the optimal solution. The compressor will turn on less often and will decrease. However, products that require deep freezing (-18°C and below) cannot be stored in such conditions. electricity consumption will decrease. However, products that require deep freezing (-18°C and below) cannot be stored in such conditions.

Use the table above for guidance in possible use scenarios. Remember that prolonged operation at elevated temperatures in the freezer compartment may require more frequent defrosting if you do not have a system No Frost.

Technical nuances and limitations of No Frost systems

The system No Frost assumes the presence of fans and defrost heaters. Even if you increase the temperature in the freezer to positive values, the system may periodically turn on the heating element to defrost the evaporator. This is a normal process, but it means that a complete “rest” from electricity will not be possible.

In refrigerators with one evaporator located in the freezer, cold is supplied to the main compartment through special channels with dampers. By adjusting damper, you can let more cold down, but the reverse process (heat from bottom to top) is limited by design. Therefore, it is physically difficult to completely “turn off” the freezer, leaving the cold at the top, in such systems without disrupting air circulation.

What happens to the oil in the compressor during frequent cycles?

With frequent switching on and off or operating in abnormal temperature conditions, the oil in the compressor may not have time to return to the crankcase, which leads to accelerated wear of rubbing parts. Try not to keep the refrigerator in border modes for too long.

It is also worth considering that when the temperature in the freezer increases, condensation may form on the walls if the humidity in the room is high. In systems No Frost moisture is removed, but if the factory settings are changed, the fan operation algorithm may become ineffective for removing moisture at new temperature gradients.

Frequent errors when trying to turn off

When trying to solve the problem of how to turn off the freezer in an Ariston refrigerator, users often make mistakes that can lead to breakdown of equipment. The most common of them is an attempt to seal the temperature sensor or forcefully clamp the thermostat contacts. This leads to the compressor working without stopping, which is fraught with burnout for several days.

Another mistake is completely blocking the ventilation holes between the chambers in the hope of insulating the freezer. In systems with forced circulation, this creates excess pressure and load on the fan, and also upsets the thermal balance. Air exchange must remain free even if you change the temperature settings through the control panel.

You should also not ignore the sound signals. If, after changing the settings, the refrigerator begins to make unusual sounds (gurgling, humming), return the settings to the factory settings. This may mean that refrigerant circulates in abnormal mode, which is dangerous for the capillary tube.

⚠️ Attention: Technical characteristics and control interfaces may vary depending on the year of manufacture and the specific series of the Ariston refrigerator. If the described actions do not correspond to your control panel, please refer to the manufacturer's official documentation.

FAQ: Frequently asked questions

Is it possible to completely turn off the freezer while leaving the refrigerator running?

In most models Ariston with one compressor, completely turn off freezer while leaving the refrigerator compartment running is impossible. You can only increase the temperature in the freezer compartment to the values ​​of the refrigerator if the design allows independent adjustment.

Why, after increasing the temperature in the freezer, does it start to freeze again?

This may be due to the operation of protective algorithms. If the sensors detect that the temperature in the main chamber is rising due to a lack of cold (which is usually taken from the freezer), the system will forcefully start a freezing cycle to restore the balance.

Is it safe to keep the freezer at 0 degrees all the time?

Yes, it is safe for technology, but it is pointless from a storage point of view. At 0°C, food does not freeze, but it is not stored as long as at +4°C. It is better to use this volume as additional refrigeration space, if the model allows such a setting.

How to reset the temperature settings to factory settings?

Usually, to reset, you need to unplug the refrigerator from the outlet for 10-15 minutes. On electronically controlled models, you may need to press a combination of buttons (for example, “Lock” and “Temp”) for 5-10 seconds. For the exact combination, see the instructions for your model.
