Modern refrigeration units of the Italian brand Hotpoint Ariston are famous for their reliability and thoughtful design, but even the highest quality devices sometimes need to manually adjust the settings. The owner may encounter a situation where the food in the main chamber begins to freeze or, conversely, the milk sours faster than expected. In such cases, competent temperature adjustment becomes the only correct solution to the problem, allowing you to restore the optimal microclimate inside the equipment.
Before you start actively rotating knobs or pressing buttons, it is important to understand that setting climate parameters is not just a mechanical action, but a process requiring an understanding of the operating principles of your specific unit. Different models Hotpoint Ariston are equipped with different control systems: from classic mechanical thermostats to modern electronic panels with a digital display. Incorrect interpretation of readings or chaotic changes in parameters can lead to increased load on the compressor and increased energy consumption, which in the long term will negatively affect the service life of the equipment.
In this article we will analyze in detail the algorithms of action for various modifications of refrigerators, explain the physics of the cooling process and give recommendations for seasonal adaptation of settings. You will learn why you cannot immediately set the minimum values and how to determine whether your unit is operating normally. Understanding these nuances will help you not only maintain the freshness of your food, but also extend the life of your household appliances.
Determining the type of refrigerator control system
The first step towards the ideal temperature is visual identification of the control panel. In the line Hotpoint Ariston there are two main types of interfaces, each of which dictates its own approach to configuration. Mechanical thermostats are a rotary dial, often located inside the refrigerator compartment or on the top of the cabinet, and do not have a digital display. Electronic control, in turn, is characterized by the presence of buttons and a screen displaying current degrees or operating mode codes.
If you find a round disk inside the camera with numbers from 1 to 5 or from Min to Max, then you have to work with mechanical thermostat. Its operating principle is based on opening and closing an electrical circuit when a certain temperature is reached, which is a time-tested, although less accurate technology compared to electronics. In such models, the numbers do not indicate degrees Celsius, but only indicate the intensity of cooling: the higher the number, the colder inside.
Owners of models with a display on the door or inside the chamber are luckier, since they can see the exact temperature values in real time. Electronics allows you to set parameters with an accuracy of one degree, which is especially important for storing specific products that require strict adherence to temperature conditions. However, the presence of electronics imposes its own limitations: such systems are sensitive to power surges and require more careful handling when resetting settings.
⚠️ Attention: Before starting any manipulations with the regulators, make sure that the refrigerator is connected to the network and is operating normally. A sudden change in settings on a running compressor can cause water hammer in the cooling system if the difference is too contrasting.
Determining the type of control is the foundation for further actions. Misidentification can result in you searching for buttons that don't exist or turning the knob in the wrong direction. If you are not sure about the type of your model, refer to the technical documentation or find the exact name of the model on the nameplate, usually located inside the chamber or on the back wall.
Setting the Hotpoint Ariston mechanical thermostat
Temperature adjustment in refrigerators Hotpoint Ariston with mechanical control is done by turning a special thermostat disk. This element is most often located on the inner wall of the refrigerator compartment, sometimes hidden behind a decorative panel or located in the upper part of the compartment. The regulator scale can contain numbers (usually from 1 to 5 or from 1 to 7) or letters (Min, Max). It is important to remember the golden rule: turning towards an increasing number or to the Max value increases cooling, making it colder inside.
Many users make the mistake of believing that the number on the regulator corresponds to the temperature in degrees. This is wrong. Position "3" on a mechanical thermostat Hotpoint usually corresponds to the factory settings, providing a temperature of about +4...+5°C in the center of the chamber. Shifting the regulator to the "5" or "Max" position will force the compressor to work almost non-stop, trying to reach the lowest possible temperatures, which can lead to freezing of the back wall and spoilage of vegetables.
The setup process should be smooth. It is not recommended to turn the knob immediately from minimum to maximum. Make a slight turn, literally one notch, and wait a few hours. The thermostat and evaporator need time to stabilize the temperature throughout the entire volume of the chamber. Sudden changes in settings can cause food in the upper drawers to freeze before the lower drawers have time to cool.
Seasonality plays an important role when using mechanical models. In the summer, when the ambient temperature in the kitchen is high, it may be necessary to move the control one notch towards stronger cooling to compensate for heat gain. In winter, on the contrary, in a heated room, the load on the unit is reduced, and the position of the regulator can be left at average values or even slightly reduced in order to save energy.
Temperature control in models with electronic control
Electronic control systems in refrigerators Hotpoint Ariston provide the user with advanced control capabilities. The control panel can be located on the outside of the door or inside the refrigerator compartment. To change parameters, you must use touch buttons or mechanical keys located next to the display. Typically the process is as follows: pressing the compartment selection button (refrigerator or freezer) activates the temperature indicator to flash, after which the “+” or “-” buttons are used to set the desired value.
The optimal temperature for the refrigerator compartment is considered to be the range from +3°C to +5°C. It is within these limits that bacteria multiply slowest, and products retain their taste for the longest possible time. If you set the value to +2°C, be prepared for the fact that food placed against the back wall may freeze. A value above +6°C is already considered dangerous for long-term storage of perishable products such as meat, fish and dairy products.
In models with the system No Frost electronics also controls fans and defrost cycles. Temperature changes may affect how often these cycles occur. If you notice that after resetting the chamber has become too dry or, conversely, damp, it may be worth adjusting the temperature regime or checking how tightly the door is closed. Electronics react faster than mechanics, but here it also takes time to stabilize - usually about 6-8 hours to completely equalize the temperature throughout the entire volume. Some advanced models are equipped with an “Eco” or “Energy Saving” mode, which automatically sets the temperature to about +5...+6°C. This is an economical mode, suitable for storing drinks or foods with a long shelf life, but not recommended for meat and fish. Switching to this mode is carried out by a separate button, and it can block manual setting of lower temperatures.

Optimal temperature conditions for different products
Understanding which products are stored best at what temperature will help you set up the refrigerator Hotpoint Ariston most effective. There is no universal value for all products, so it is important to know the specific storage areas inside your unit. The temperature is distributed unevenly: it is colder on the shelves at the back wall, warmer on the door, and the lower vegetable drawers maintain their own microclimate.
The following is a table of recommended temperature conditions for the main categories of products:
| Product category | Recommended temperature | Storage area in the refrigerator | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and poultry | 0°C ... +2°C | Lower shelf, freshness zone | 1-2 days |
| Dairy products | +2°C ... +4°C | Middle shelves, not on the door | 3-5 days (after opening) |
| Vegetables and fruits | +5°C ... +8°C | Bottom drawers (containers) | 3-7 days |
| Ready meals | +3°C ... +5°C | Middle and upper shelves | 1-2 days |
The “zero freshness” zone, if provided for by the design of your Hotpoint Ariston, is an ideal place for storing chilled fish, meat and delicacies. In this compartment, humidity and temperature are maintained at a level as close as possible to 0°C, but without freezing the water. This allows you to preserve the structure of products and their benefits much longer than in the main chamber.
Door shelves are the warmest place in the refrigerator. You should not store milk or open deli meats here, as temperature fluctuations when opening the door can cause spoilage. The door is ideal for sauces, drinks, eggs and products containing preservatives, which are less demanding of strict temperature conditions.
Seasonal adjustment and the influence of external factors
The temperature inside the refrigerator directly depends on the ambient temperature. In the summer, when the kitchen can be hot, the insulation works less effectively and the compressor has to work harder. During this period, you may need to slightly adjust your thermostat settings to increase cooling, especially if you notice that food is spoiling faster. However, you should not be zealous: setting the “Max” mode in hot weather can lead to overheating of the compressor.
In winter, the situation changes. If the refrigerator is in a cool room or next to a window, heat gain is reduced. Under these conditions, the mechanical thermostat may turn on the compressor less frequently, which sometimes results in insufficient cooling of the freezer compartment in single-compressor models. Here, on the contrary, a slight adjustment may be required in the direction of increasing power, but most often it is enough to leave the settings at the factory level.
⚠️ Attention: Do not install the refrigerator Hotpoint Ariston near heat sources (stoves, radiators) or in direct sunlight. This makes any temperature adjustment pointless, since the unit will work for wear, trying to compensate for external heating.
It is also worth considering the fullness of the chambers. A fully loaded refrigerator holds cold better, but takes longer to return to operating mode after loading warm food. An empty refrigerator responds faster to changes in settings, but when the door is opened, the temperature in it jumps more sharply. Try not to fill the chamber to capacity, leaving space for air circulation, especially in models with the No Frost system.
☑️ Checklist for proper operation
Diagnosis of problems with incorrect settings
If after adjusting the temperature you notice strange phenomena, this may indicate a malfunction or improper operation. For example, the formation of a “fur coat” or ice crust on the back wall of the refrigerator compartment when a mechanical thermostat is operating often indicates that the regulator is turned up to maximum and the food is lying close to the evaporator. In models with No Frost, the appearance of ice indicates problems with the defrost system or a loose seal, and not the temperature settings.
Continuous operation of the compressor without stopping is another alarming symptom. If you have set the average values, and the motor hums continuously, check whether the chamber is overloaded with warm food. The cause may also be clogged ventilation ducts or a faulty temperature sensor. In such cases, simple temperature adjustment will not help, and you will need to call a technician.
Why does the refrigerator make noise after adjustment?
Increasing noise after increasing the cooling power is normal. The compressor works harder and the refrigerant moves faster. If knocking, creaking, or humming becomes unnaturally loud, check whether the refrigerator is touching walls or furniture, and make sure it is level.
Insufficient cooling when the thermostat is turned to maximum may indicate a freon leak or compressor failure. Before you panic, try defrosting your refrigerator (if it's not No Frost) and check if the drain holes are clogged. Sometimes simple maintenance solves the problem better than complex diagnostics.
Frequent questions and answers (FAQ)
What temperature should be in the Hotpoint Ariston freezer?
The optimal temperature for the freezer is -18°C. At this value, products can be stored for up to 12 months without loss of quality. Setting lower temperatures (for example, -24°C) only makes sense in the Super Freeze mode for a short time.
Why does the temperature not change immediately after adjustment?
The refrigerator needs time to stabilize heat exchange processes. The air must cool, the walls of the chambers must freeze to new values. This process usually takes from 4 to 8 hours. Do not change the settings again during this time.
What to do if the refrigerator is too cold even at minimum?
If the mechanical thermostat control is set to “1” (minimum), and the food freezes, the thermostat itself or the temperature sensor may be faulty. Also check to see if the heat sensing tube is too tight on the evaporator. In this case, the help of a specialist is necessary.
Does the "Super Cool" mode affect the normal operation of the refrigerator?
Yes, the "Super Cool" mode forces the compressor to operate continuously to quickly cool a large volume of food. Do not keep this mode turned on constantly, as this leads to excessive energy consumption and freezing. Turn it off manually or watch the timer, if there is one.
Is it possible to turn off the refrigerator at night to save money?
It is strictly not recommended to turn off the refrigerator often or do it for short periods of time. This disrupts the food storage mode and forces the compressor to work with increased load the next time it is turned on. It’s better to set the temperature correctly once than to constantly jerk the device.
