Correct adjustment of climatic parameters in the refrigeration chamber is the foundation for long-term storage of products and preservation of their taste. Ariad refrigerators They are famous for their reliability, but even the most advanced equipment requires a competent approach to operation for effective operation. Many owners are faced with a situation where the food in the chamber either freezes or, conversely, begins to deteriorate faster than expected.
The optimal temperature regime directly affects the energy consumption of the device and the service life of the compressor. If you set the values too low, the unit will work for wear, trying to achieve unattainable parameters, which will lead to the formation of an ice crust on the walls. At the same time, insufficient cold creates ideal conditions for the growth of bacteria, which is dangerous to health.
In this article we will look in detail at how to properly configure thermostat in various models of Ariada refrigerators, and we will explain what the numbers on the scale mean. You will learn about the nuances of the operation of mechanical and electronic control systems, and also receive answers to questions that often arise during the initial installation of equipment.
The principle of operation of the thermostat in Ariada refrigerators
The main element responsible for maintaining cold in the chambers of Ariada refrigerators is thermostat. This device monitors the temperature inside the refrigerator compartment and signals the compressor to turn on or off. Depending on the model of your refrigerator, control may be mechanical or electronic. Understanding the principle of operation of this unit will help you avoid mistakes when setting up.
In mechanical systems, adjustment is made by turning the handle, which changes the tension of the spring inside the thermostat. Thermoregulator does not measure temperature in degrees directly at the moment of rotation; it only sets the response threshold. When the air inside the chamber cools to a predetermined level, the circuit opens and the compressor stops. As the temperature rises, the process repeats.
How does the capillary tube of a thermostat work?
Inside the mechanical thermostat there is a sensitive capillary tube filled with gas or liquid. It is attached to the evaporator or inserted into the chamber. When the temperature changes, the volume of the substance in the tube changes, which is transmitted to the membrane and opens or closes the electrical contacts. This is a simple but extremely reliable mechanism that does not require complex electronics.
Electronic control systems found in more modern or industrial models use temperature sensorswhich transmit data to the controller. The control unit itself makes the decision to start the compressor, ensuring more accurate compliance with the specified parameters. However, the principle remains the same: maintaining a balance between the production of cold and heat inflow from the outside.
Interpretation of the thermostat scale: what do the numbers mean
One of the most common questions from owners of Ariada equipment concerns the decoding of the numbers on the rotary knob of the thermostat. There is often a misconception that the numbers represent degrees Celsius, but this is not the case. The scale from 1 to 7 (or from Min to Max) indicates cooling intensity, and not a specific temperature.
The higher the number you set on the regulator, the colder it will be in the refrigerator compartment. For example, position “1” corresponds to the minimum production of cold (highest temperature), and position “7” corresponds to maximum (lowest temperature). If the knob is set to an intermediate position, the compressor will turn off when the middle threshold is reached.
- 🔹 Positions 1-2: Economy mode, the temperature in the chamber can reach +8...+10°C, suitable for storing vegetables that do not require strong cooling.
- 🔹 Positions 3-4: Standard operating mode, providing temperature about +4...+5°C, ideal for most products.
- 🔹 Positions 5-7: Intensive cooling mode, the temperature can drop to 0°C and below, which is dangerous for some types of products.
It is important to understand that The actual temperature inside the chamber depends not only on the position of the handle, but also on external factors. The load on the refrigerator, the room temperature, how often the door is opened and the tightness of the seals all affect the final result. Therefore, the numbers on the scale should be perceived as relative power values.
Step-by-step instructions: how to set the optimal temperature
To set up the Ariad refrigerator, you do not need complex tools or special knowledge. The entire process takes a few minutes, but requires attention to detail. Before you start adjusting, make sure that the refrigerator is connected to the network and is operating normally for at least several hours.
Find the thermostat. In most models of Ariada refrigerators, it is located inside the refrigerator compartment on the right wall or on the ceiling, sometimes hidden by a plastic casing. Carefully remove the cover, if equipped, to gain access to the handle. Turn the knob smoothly, without sudden jerks, so as not to damage the internal mechanism.
☑️ Temperature setting algorithm
It is recommended to start setting from the middle position of the scale (usually numbers 3 or 4). After changing the position of the regulator, you must wait 6 to 12 hours. This time is necessary to stabilize the temperature and completely freeze the internal volume. Only after this can you objectively evaluate the result and, if necessary, make adjustments.
⚠️ Attention: Do not try to turn the thermostat knob when the compressor is running at maximum or making strange sounds. Let the system calm down. A sudden switch from minimum to maximum can cause a voltage surge in the engine starting system.
If, after the initial setting, the products in the upper part of the chamber remain warm and freeze at the bottom, try lowering the value by one. And vice versa, if the refrigerator “does not work” and the food spoils, add power by turning the knob towards larger numbers. Remember that stability more important than extreme values.
Table of recommended modes for different products
The variety of products that we store in the refrigerator dictates different temperature requirements. To optimize the performance of your Ariad refrigerator, it is useful to know what conditions are preferable for different groups of goods. Below is a table that will help you navigate the settings.
| Product type | Recommended temperature | Knob position (approx.) | Term storage |
|---|---|---|---|
| Meat, fish, poultry | 0°C ... +2°C | 5-6 | 2-4 days |
| Dairy products | +2°C ... +4°C | 3-4 | 3-7 days |
| Vegetables, fruits | +4°C ... +8°C | 2-3 | 5-10 days |
| Ready meals | +2°C ... +5°C | 3-4 | 1-3 days |
| Eggs | +2°C ... +6°C | 3-4 | up to 20 days |
It is worth noting that modern refrigerators often have zones freshness or special shelves where the temperature may differ from the general temperature in the chamber. In such areas, conditions may be wetter or, conversely, drier. Use these features to accommodate the most sensitive products.
Do not forget that a full refrigerator requires a more powerful operating mode than an empty one. If you have just returned from the store with a full package of groceries, you can temporarily increase the cooling power and then return the regulator to the standard position.
The influence of external factors on the temperature regime
The efficiency of the Ariad refrigerator depends not only on the internal settings, but also on environmental conditions. The temperature in the room where the unit is located plays a critical role. If the room is hot, the compressor has to work longer and harder to maintain the desired indoor climate.
The location of the refrigerator also matters. It is not recommended to install equipment in close proximity to heating appliances, stoves or in direct sunlight. Heat inflows The outside makes the thermostat “think” that it has become warmer inside, and it turns on the motor more often than expected, which can lead to incorrect operation.
- 🌡️ Room temperature: Optimal range from +16°C to +32°C (climate class). Exceeding these limits may interfere with operation.
- 🚪 Opening frequency: Each opening of the door releases cold air and admits warm air. The more often this happens, the more difficult it is for the system to restore balance.
- 🧊 Presence of ice: A thick layer of ice on the evaporator acts as a heat insulator, interfering with cooling. Regular defrosting is necessary.
It is also worth considering the tightness of the door. If the sealing rubber is worn out or dirty, the cold will escape constantly. Check the integrity of the seal: it should fit tightly around the entire perimeter. If necessary, wipe it with a soft cloth or replace it.
Typical errors during setup and their consequences
Improper operation of refrigeration equipment can lead to serious consequences, including failure of expensive components. One of the most common mistakes is setting the regulator to the maximum value (7 or Max) in the hope of cooling food faster. This is a misconception: the compressor operates with the same power, the only difference is the shutdown temperature.
Constant operation at maximum leads to the fact that the evaporator becomes overgrown with a “fur coat”, ventilation is disrupted, and the compressor works without interruption. This causes overheating of the motor windings and reduces the life of the refrigerator. In addition, the products in such a chamber can freeze, losing their structure and taste.
⚠️ Attention: If you notice that the back wall of the refrigerator compartment is completely covered with ice, and the products at the back wall are frozen, this is a signal that the thermostat setting is too low or problems with the defrosting system. Reduce power immediately.
Please note that specifications and control interfaces may vary slightly depending on the year of manufacture of a particular model. It is recommended to check the current parameters in the official user manual of your device.
The other extreme is setting the minimum power in the hot season. In this case, the refrigerator simply will not be able to compensate for the heat gain, and the food will begin to deteriorate, especially in the upper sections of the chamber. Bacteria actively reproduce at temperatures above +6°C.
Frequently asked questions (FAQ)
Why does the Ariada refrigerator not turn off after changing the settings?
If you have just changed the position of the thermostat, give the device time (up to 12 hours) for stabilization. If the refrigerator runs non-stop for days, check the door tightness, the presence of ice on the evaporator and the correct temperature setting. The thermostat may be faulty.
What to do if the refrigerator is too cold on the minimum setting?
This may indicate a malfunction of the thermostat (sticky contacts) or problems with the temperature sensor (in electronic models). Also check whether the condensate drain channel is clogged or whether the air circulation is blocked by food. In this case, diagnostics by a specialist is required.
Is it possible to leave the Ariad refrigerator turned off in winter?
You can store it turned off, but at a temperature not lower than +5°C. Operation at low ambient temperatures (below +10°C) is not recommended, as the oil in the compressor thickens, which can lead to failure when starting. Cooling in an unheated room in winter may be ineffective.
How to understand that the thermostat is broken?
Symptoms of a malfunction: the refrigerator does not turn on at all or, conversely, it works without interruption and does not turn off even at the minimum setting; There is no cold inside the chamber or, on the contrary, everything is frozen. In such cases, replacing the thermostat yourself is only possible if you have the skills and tools.
Is it necessary to defrost the refrigerator if there is a No Frost system?
The No Frost system prevents the formation of ice on food and walls, but does not make defrosting completely unnecessary. It is recommended to turn off the device at least once a year to wash, disinfect and check the condition of the drainage system to avoid the appearance of unpleasant odors and bacteria.
