Brand refrigeration equipment Indesit is deservedly popular due to its reliability and ease of operation, however, for the unit to operate effectively, it is necessary to strictly observe the temperature regime. Correctly setting the climate inside the chambers directly affects the preservation of the freshness of products, their taste and, importantly, the service life of the compressor itself. Many owners mistakenly believe that the colder the better, but this leads to excessive consumption of electricity and spoilage of some types of food, which simply freeze.
Modern models, whether classic Indesit C 138 or a more advanced series Smart with a system No Frostrequire an individual approach to configuration thermostat. In this article, we will take a detailed look at what indicators are considered benchmarks for various departments, how to correctly set the values mechanically or electronically, and why fluctuations of even one degree can become critical for your inventory.
Understanding the principles of the cooling system will help you avoid common mistakes, such as the formation of an ice crust on the back wall or, conversely, the appearance of an unpleasant odor due to insufficient cooling. Temperature control is not just a matter of comfort, but a necessary safety measure to prevent the growth of bacteria in food.
Standard temperature standards for Indesit chambers
For most refrigerator models Indesit the manufacturer sets average parameters that are considered optimal for storing a wide range of products. In the main compartment, where we usually keep prepared food, drinks and semi-finished products, the climate must be maintained within a narrow range. The ideal temperature is considered to be from +2 to +4 degrees Celsius. It is under these conditions that the fermentation processes slow down, but the products do not freeze.
The freezer, regardless of whether it is part of a two-chamber model or a separate freezer of the series Indesit DF, must provide deep freezing. The standard indicator here is -18 degrees Celsius and below. At this value, bacteria and microorganisms completely stop their vital activity, which allows you to store meat, fish and vegetables for several months without losing their beneficial properties.
There is a so-called “zero zone” or a compartment for fresh food, which is found in more expensive configurations. Here the temperature stays around 0 degrees, which is ideal for meats, fish and cheeses intended for quick consumption. It is important to understand that cold distribution in the chamber it is uneven: it is always colder at the back wall, and warmer at the door.
⚠️ Attention: If you notice that a “coat” of ice with a thickness of more than 5 mm is formed on the walls of the chamber, or products are in the depths the shelves freeze, but the shelves near the door are warm, this is a signal of a faulty seal or malfunction of the thermostat, and not of an incorrect setting.
Setting the mechanical and electronic thermostat
The method of adjusting the temperature in refrigerators Indesit directly depends on the type of control panel installed. Classic models, such as Indesit C 138 G or Indesit C 190, use a mechanical thermostat. It is a rotary knob inside the refrigerator compartment, usually located in the upper corner or under the ceiling light. The scale can contain numbers from 1 to 5 or from MIN to MAX.
It is important to remember the main rule of mechanical adjustment: the number does not mean degrees Celsius, it indicates the intensity of the compressor. The higher the number you set, the colder it will be inside. For everyday use optimal position handle the value is considered to be "3". If you loaded the chamber with a large amount of warm products after the store, you can temporarily increase the power to “4” or “5”, but then be sure to return the regulator to the normal position.
Electronic control, typical for series Indesit Smart or models with a display on the door, allows you to set the temperature with an accuracy of a degree. Control is carried out via touch buttons or a rotary encoder. Here you see real numbers, which greatly simplifies control. To change the settings, you often need to press and hold the setting button for 3-5 seconds, after which the indicators begin to flash.
☑️ Checking the thermostat settings
When using an electronic display, you should pay attention to the alarm indicators. If the red icon lights up or a beep sounds, it means that the temperature inside the chamber is above the permissible norm. In this case, the system can automatically turn on the mode super freezing (snowflake icon) to quickly cool the internal volume.
Table of temperature conditions for different products
Not all products require the same storage conditions. A mistake many users make is storing all the contents in one pile on the middle shelf. For maximum shelf life, it is necessary to zone the refrigerator space Indesitbased on the physics of cold distribution and the requirements for specific types of food.
Below is a table that will help you correctly distribute supplies on the shelves so that they remain fresh for as long as possible. Compliance with these recommendations is especially important in the summer, when the load on the compressor increases.
| Product type | Recommended temperature | Space in the Indesit refrigerator | Shelf life (approximate) |
|---|---|---|---|
| Raw meat, fish | 0 ... +2°C | Lower shelf (closer to the back wall) | 1-2 days |
| Dairy products | +2 ... +4°C | Middle shelves, away from the door | 3-5 days |
| Vegetables, fruits | +4 ... +6°C | Bottom drawers (freshness zone) | 3-7 days |
| Ready dishes, sauces | +2 ... +5°C | Upper and middle shelves | 2-3 days |
| Eggs, butter, drinks | +4 ... +8°C | Shelves on the door | 7-14 days |
Please note that the door is the warmest place in the refrigerator due to constant contact with the warm air of the room when opening. Therefore, storing perishable products such as milk in open packaging or raw meat there is strictly not recommended. It is better to place sauces, drinks and foods with a long shelf life there.
Why can’t you put hot food in the refrigerator?
Placing hot foods disrupts the temperature balance, causing the compressor to work harder. In addition, warm steam condenses on the walls, forming ice, which impairs heat transfer and can lead to breakdown of the moisture removal system.
The influence of the No Frost system and drip defrosting
Cooling technology plays a key role in the formation of the microclimate. Refrigerators Indesit with a drip system (Static) operate on the principle of natural convection. Cold air goes down and warm air rises. In such models, the temperature difference between the top and bottom shelves can reach 2-3 degrees. Therefore, it is especially important here to distribute the products correctly: the coldest ones are down, those that are afraid of frost are higher.
Models with the system No Frost (for example, series Indesit DF) are equipped with a fan that forcibly circulates cold air throughout the chamber. This ensures a more uniform temperature throughout the entire volume, minimizing differences. However, this system has a peculiarity: the air in such refrigerators is very dry. This is great for preventing mold, but bad for products that quickly dry out or lose moisture.
Humidity control in No Frost systems is achieved through sealed vegetable boxes. If you are the owner of such a model, be sure to cover meat and fish products with film or containers, otherwise they may dehydrate ("burn" in the cold) even at the correct temperature.
It is important to note that in refrigerators No Frost the temperature is restored faster after opening the door, but noise from the fan can also be heard. This is a normal operating characteristic and not a sign of failure.
Seasonal adjustments and external factors
The temperature inside the refrigerator Indesit depends not only on the thermostat settings, but also on environmental conditions. In summer, when the temperature in the kitchen reaches +25...+30 degrees, heat exchange is disrupted. The compressor requires more time and energy to remove heat from the chambers through the condenser (grid at the back or sides). During this period, a slight increase in internal temperature may be observed even with standard settings.
In winter the situation is reversed. If the refrigerator is in an unheated room or next to a window, where the temperature drops below +10 degrees, the compressor may not turn on at all, since it “seems” that it is already cold inside. This is especially critical for the freezer, where food may begin to defrost.
⚠️ Attention: Do not install the refrigerator Indesit closer than 50 cm to heat sources (stove, radiator) and do not place it in direct sunlight. This will lead to constant overheating of the compressor and failure to maintain the temperature regime, regardless of the settings.
If you notice that on hot days food begins to spoil faster, try moving the mechanical thermostat control one notch towards lower temperatures (to a larger number). For electronic models, it is enough to manually lower the target temperature by 1 degree. After stabilizing the indoor climate, return the settings to their original position.
Diagnostics of cooling problems
Sometimes users are faced with a situation where the settings are set correctly, but the temperature does not meet the requirements. The first sign of a malfunction is the formation of a large amount of ice in the refrigeration chamber of models with a drip system or the appearance of ice in the lower part of the freezer in systems No Frost.
The second alarming symptom is the constant operation of the compressor without shutting off. If the engine hums continuously, trying to get cold, but does not reach the target levels, this may indicate a freon leak or compressor wear. The third sign is frequent turning on and off of the unit (clocking), which also indicates problems with thermoregulation.
For initial diagnosis, you can use a simple method: place a glass of water and ordinary with an outdoor thermometer on the middle shelf of a working refrigerator for 2-3 hours. If the device readings differ greatly from those shown on the display or the expected values, a call to the technician is required.
Why does ice freeze in the Indesit refrigerator if the correct temperature is set?
Ice can form due to a loose door, damage to the sealing rubber, or a clogged drainage hole. It may also be caused by placing foods with a high moisture content in the chamber without packaging. In No Frost systems, ice in the refrigerator compartment indicates a malfunction of the defrost system.
Is it possible to set the temperature below -24°C in an Indesit freezer?
Technically, some models allow you to set extremely low values in the super-freeze mode, but constantly maintaining such a temperature (-24°C and below) is impractical. This leads to a sharp increase in energy consumption and increased load on the compressor, without giving a significant gain in shelf life compared to standard -18°C.
How often do you need to defrost an Indesit refrigerator with a drip system?
Despite the presence of an automatic defrosting system ("crying wall"), manufacturers recommend complete defrosting and Cleaning the refrigerator compartment 1-2 times a year. This is necessary to remove bacteria that do not die at low temperatures, and to clean drainage channels that can become clogged with food debris.
What to do if the temperature is not restored after defrosting?
After defrosting, the refrigerator takes time (from 2 to 6 hours) to return to operating mode. Don't load it with products right away. If within 6-8 hours with empty chambers and correct settings the temperature does not drop to normal, there may be damage to the circuit due to ice chipping or an electronic malfunction.
