The situation when food in the refrigerator Ariston begins to spoil faster than usual or is simply not cooled enough is familiar to many owners of this equipment. Often the problem can be solved by simply adjusting the settings, since the factory settings may not correspond to the current operating conditions or the number of loaded products. Understanding the principles of operation of the cooling system will help you quickly establish the ideal microclimate inside the chambers.
The first thing you need to do is determine the type of control of your device. Models can be equipped with a mechanical regulator, an electronic display or a combined system. Incorrect setting can lead not only to food spoilage, but also to increased energy consumption or freezing of the evaporator. In this material we will analyze all the nuances of adjustment for different series of equipment.
Before taking active steps, make sure that the refrigerator has been operating normally for several hours after turning on or defrosting. A sudden drop in temperature immediately after loading a large volume of warm food is a normal compressor reaction, but it takes time to stabilize. Let's look at the main methods of influencing climate parameters.
Features of the Ariston temperature control system
Brand refrigerators Ariston, like many other modern models, are divided into devices with a drip system and technology No Frost. In the first case, cooling occurs due to natural air convection, and moisture settles on the back wall and flows into the drain. In the second, air is forced to circulate through the evaporator, which requires more precise settings to prevent overdrying of products.
Electronic control allows you to set the temperature with an accuracy of a degree, while mechanical thermostats work on the “more or less” principle. If you have a model with a display, you can see the current readings in real time. For mechanical regulators, it is important to understand that the numbers on the scale do not mean degrees Celsius, but indicate cooling intensity.
It is important to consider the location of the temperature sensors inside the chamber. They can be located in different places: on the back wall, at the top or even in the door, causing the compressor to idle or, conversely, turn off ahead of time. Always leave free space around the air ducts. Densely loading food directly in front of the sensor may distort the readings, causing the compressor to idle or, conversely, shut down ahead of time. Always leave some space around the air ducts.
⚠️ Attention: If you change the settings, give the refrigerator 5-6 hours to stabilize the temperature. Do not try to turn the regulator every 30 minutes, trying to speed up the process - this will only disrupt the automation.
Modern models are often equipped with the “Smart Cooling” function or Smart Cooling, which automatically adapts the operation of the compressor to external conditions. However, even such systems require initial calibration by the user depending on the season and the fullness of the chambers.
Adjusting a mechanical thermostat
In classic models Ariston control is carried out using a rotary knob located inside the refrigerator compartment, usually in the upper corner or on the ceiling. The scale can contain numbers from 1 to 5, from 1 to 7 or designations Min and Max. A simple rule applies here: the higher the number, the lower the temperature inside.
If you need to reduce the temperature, turn the knob towards the higher number. For example, if it was at "3", move it to "4" or "5". It is not recommended to immediately set the regulator to maximum, as this may lead to hypercooling products near the back wall and freezing. The middle of the scale is considered the optimal value for everyday use.
Mechanical thermostats are sensitive to sudden voltage surges and physical wear. Over time, the calibration may get lost, and position “3” will give the effect that “4” previously gave. In such cases, an experimental selection of the position of the handle with temperature control using an external thermometer is required.
⚠️ Attention: Never use excessive force when turning the handle. The thermostat mechanism is fragile, and its failure will require replacing the entire assembly, which is an expensive procedure.
Remember that mechanical adjustment affects all chambers at once if you have a single-compressor model. By changing the settings in the refrigerator compartment, you automatically change the mode in the freezer compartment, which must be taken into account when storing frozen foods.
Setting up the electronic display and touch panels
Owners of refrigerators Ariston with electronic control are more fortunate: they can see the exact temperature and adjust it independently for the refrigeration and freezer compartments. Control is usually carried out through buttons on the front panel of the door or via a touch screen. To enter the setting mode, you often need to hold the button Set or Temp for 3-5 seconds.
To reduce the temperature, use the arrow buttons Up and Down or symbols + i -. The recommended temperature for the refrigerator compartment is +3°C to +5°C. For the freezer, the optimal value is -18°C. Reducing the temperature below -24°C in the freezer is usually not necessary and leads to waste of energy.
Some models are equipped with a function Fast Freeze (Quick freezing) or Super Cool. Activating these modes temporarily places the compressor at maximum power to quickly cool newly loaded food. However, you cannot keep these modes turned on all the time - this can lead to freezing of the channels and damage to the fan.
☑️ Checking the display settings
If the display flashes or shows an error (for example, E1, E2), this may indicate a malfunction temperature sensor. In this case, manual adjustment will not help - diagnostics by a specialist is required. Also pay attention to the open door indicator, which may interfere with the normal operation of the electronics.
Use of special cooling modes
Modern refrigerators Ariston offer a number of special functions to optimize operation. The mode Eco is designed to save energy, but it maintains the temperature at the upper limit of normal. If your goal is to cool the food as much as possible, this mode needs to be turned off.
Function Holiday Mode (Vacation mode), on the contrary, increases the temperature in the refrigerator compartment to +12...+15°C to prevent the appearance of mold in the absence of owners, but keeps the freezer working. Make sure this mode is turned off if you need regular cooling. Activation is often done by long pressing a button with the image of a palm tree or a snowflake.
Mode Super Cool (Super cooling) is useful when you have just returned from the store with a full bag of groceries. It forcibly cools the chamber to +2°C for several hours, and then automatically returns to the set values. This is a great way to quickly lower the temperature without the risk of forgetting to switch the settings back.
⚠️ Attention: Special energy modes may limit the maximum compressor power. If you urgently need to reduce the temperature, make sure that the Energy Saving mode is deactivated.
Factors affecting cooling efficiency
Even with the correct settings, the temperature may not drop to the desired value due to external factors. One of the main enemies of effective cooling is loose door fit. Check the rubber seals: if they are dirty or deformed, cold air leaves, and warm air gets inside, causing the compressor to wear out.
The location of the refrigerator also plays a role. If Ariston stands close to a wall or in a niche without gaps for ventilation, heat is not removed from the condenser. This leads to overheating of the unit and reduced cooling efficiency. The minimum gap to the rear wall should be 5-7 cm.
The load on the chambers affects thermal stability. An empty refrigerator cools down faster, but holds the temperature worse when the door is opened. A completely clogged unit disrupts air circulation. Ideal condition - filling approximately 60-70% of the volume.
| Influence factor | Influence on temperature | Recommended action |
|---|---|---|
| Loading density | High density violates circulation | Leave gaps between products |
| Temperature in the room | Heat above +30°C reduces efficiency | Ventilate the kitchen, do not place near the stove |
| Cleanliness of the condenser | Dust impairs heat transfer | Clean the grille at the back every six months |
| Tightness | Cracks in the seal let heat in | Wash the rubber band and check the fit |
It is also worth mentioning the number of door openings. Frequently looking inside leads to heat loss. If you have a large family, agree to get everything you need at one time to minimize the time the door is open.
Diagnosing faults with insufficient cooling
If you set the minimum temperature, checked all the modes, but the cold did not appear, it may be a technical fault. One of the first symptoms is thermostat malfunction. If it is “stuck,” the compressor may not turn on at all or work without stopping, not producing cold.
Another common problem is a refrigerant (freon) leak. In systems No Frost this may be accompanied by noise or its absence (the compressor hums, but there is no cold). In drip systems, a sign of a leak is often swelling of the rear wall of the refrigeration chamber or the absence of a characteristic gurgling sound.
Clogged capillary tube or filter-drier also leads to disruption of freon circulation. In this case, the compressor may operate jerkily or overheat. It is difficult to fix this problem on your own; the system must be evacuated and refilled.
⚠️ Attention: If you hear clicks when you try to start the compressor, but it does not start, immediately unplug the device. This may indicate a malfunction of the start relay or the compressor itself, and further work will lead to burning of the wiring.
Prevention and care of the cooling system
To prevent the question “how to reduce the temperature in an Ariston refrigerator” from arising too often, it is important to regularly service the equipment. It is recommended to defrost the refrigerator every six months (even systems No Frost require preventive defrosting once a year for hygiene and checking drainage).
Clean the ventilation holes inside the chamber from dust and food particles. A clogged cold air supply duct is a common cause of local overheating. Use a soft brush or a vacuum cleaner at low speed to clean the rear grille.
Remember to check the installation level of the refrigerator. If it is skewed, the door may not close tightly on its own. Adjust the front legs so that the body leans back slightly, ensuring automatic slamming.
Frequently asked questions (FAQ)
Why does the Ariston refrigerator hum, but does not get cold after adjustment?
This may indicate that the temperature controller is working properly and is sending a signal, but there is a problem with refrigerant (leakage) or compressor. It is also possible that the evaporator may freeze, blocking air circulation. Diagnostics by a technician is required.
Is it possible to set the temperature below +2°C in the refrigerator compartment?
Technically, this is possible in some models, but is not recommended. At temperatures below +2°C, vegetables and fruits begin to freeze and lose their taste, and dairy products may separate. The optimal range is +3...+5°C.
How to understand that the thermostat is broken?
Main signs: the refrigerator does not turn off at all (works around the clock) or does not turn on at all, despite turning the knob. Another symptom may be the absence of a click when turning the dial from maximum to minimum when the appliance is unplugged.
Does the season affect the temperature settings?
Yes, in winter in an unheated room or at low temperatures in the kitchen, the refrigerator may turn on less often. In the summer, when the room is hot, you may need to increase the cooling power (move the regulator towards higher numbers).
What to do if the temperature in the freezer is normal, but the temperature in the refrigerator is warm?
In single-compressor models, this often indicates a malfunction of the damper that regulates the flow of cold air from the freezer to the refrigerator compartment, or frosting of the duct. In two-compressor systems - for problems with the refrigeration chamber circuit or sensor.
