The situation when food in the refrigerator Indesit begins to freeze and vegetables become covered with an ice crust is familiar to many owners of this equipment. Most often this happens in the summer or when there is a sharp change in the humidity in the room, when the standard factory settings become insufficient for comfortable food storage. Users often look for a way to turn down the Indesit refrigerator in order to save supplies and return the normal microclimate inside the chambers.
The main reason for excessive cooling lies in improper operation thermostat or failures in the electronics control system. In mechanically controlled models, the position of the knob often moves accidentally, and in digital systems software errors can occur. Understanding the operating principle of your unit will allow you to quickly adjust the parameters without calling a specialist.
In this article we will look at all the possible ways to reduce the cooling temperature, from simple adjustment of the knob to complex settings in the menu. You will learn how to diagnose a sensor malfunction and when professional intervention is actually required. Proper adjustment will extend the life of the compressor and preserve food freshness.
The principle of operation of the thermostat in Indesit refrigerators
To effectively control the temperature, you need to understand how the cooling system works. Most models Indesit use a capillary thermostat that responds to changes in evaporator temperature. When the air in the chamber cools down to a predetermined limit, the contacts open and the compressor stops. If you want to reduce the power, you actually change the threshold of operation of this mechanism.
Mechanical regulators are a knob with divisions, usually from 1 to 5 or from Min to Max. Paradoxically, to lower the temperature (to make it warmer), the knob needs to be turned towards lower values. Many users make the mistake of increasing the number, thinking that they are making the cold “less,” but in fact they are increasing the work of the compressor.
In modern models with a system No Frost and electronic control, the process is controlled by a control board. Temperature sensors located inside the chambers transmit signals to the controller. Here the adjustment occurs not mechanically, but through changing the operating algorithms of the fans and compressor. An error in the operation of one of the sensors can lead to the unit operating continuously, ignoring user commands.
- 🌡️ A mechanical thermostat regulates the freon pressure in the capillary tube, opening the electrical circuit when the desired temperature is reached.
- 💻 The electronic board processes signals from several sensors simultaneously, controlling not only the cold, but also the operation defrost.
- ❄️ The system No Frost requires more precise adjustment, since dry air dries food faster at too low a temperature.
It is important to note that in two-chamber models the temperature is often regulated in only one compartment, usually in the refrigerator compartment. The freezer may have its own regulator or operate in a linked mode. Therefore, when changing settings, monitor the readings in both compartments so as not to defrost the meat reserves in pursuit of saving cucumbers.
⚠️ Attention: In older models, the thermostat may have a calibration screw under the seal. Do not try to break the seal and twist it without special equipment, as you will ruin the factory calibration, and it will be almost impossible to return everything back.
Temperature adjustment in models with mechanical control
If your Indesit is equipped with a rotary handle inside the refrigerator compartment, the setting process is as simple as possible, but requires understanding the markings. Typically the scale has numbers from 1 to 5, where 1 is the warmest mode (minimum cooling) and 5 is the coldest (maximum power). Some models use designations Min and Max, which can be misleading.
To reduce the cold, you need to turn the knob counterclockwise towards the unit. Do not make sudden movements; It is better to change the position of the regulator gradually, in increments of one division. After each change, you must wait several hours, since the inertia of the system is high, and the air in the chamber will not cool down (or heat up) instantly.
There is also a “maximum freezing mode,” which is often indicated by a snowflake or a separate button. If this mode is activated, the compressor runs without stopping, ignoring the position of the main handle. Check to see if the indicator Super Freeze or similar symbol on the panel is lit. In mechanical models, this may be a separate button that needs to be turned off.
☑️ Checking the mechanical settings
If the knob rotates freely and does not make clicks, and the temperature does not change, perhaps The thermostat has failed. In this case, its contacts can be permanently closed, causing the motor to operate continuously. Replacing this element requires calling a technician, since it is necessary to release the freon, solder a new part and refill the system.
Setting up the electronic display and control panel
In more expensive models Indesit the control is placed on an external panel with a display. Here the process of how to reduce the refrigerator looks different. Typically, the panel has separate buttons for the refrigerator (Fridge) and freezer (Freezer) compartments. Pressing the button changes the digital temperature value displayed on the screen.
For the refrigerator compartment, the optimal value is considered to be the range from +3°C to +5°C. If your setting is +2°C or lower, food will freeze. Use the + and - buttons to set the desired parameter. After confirming the setting (sometimes you need to hold the button for 3 seconds), the new mode will take effect.
Electronics allows you to set more accurate values than mechanics. However, it is important to consider seasonality here. In the summer, when the kitchen is hot, it is more difficult for the compressor to reach temperature and may run longer. In winter, on the contrary, an adjustment to lower values may be required if the room is cool, although modern models can adapt themselves.
| Mode | Temperature (HC) | Temperature (MK) | Recommendation |
|---|---|---|---|
| Eco / Standard | +4°C ... +5°C | -18°C | Daily food storage |
| Cooling | +2°C ... +3°C | -18°C | Short-term storage of perishables |
| Super freezing | Does not change | -24°C | Only for quick freezing (up to 24 hours) |
| Holiday | +10°C ... +12°C | Off | For an empty refrigerator (saving) |
Some models are equipped with the "Smart Cooling" function or Smart Cooling, which automatically selects the operating mode. If you notice that the refrigerator has started to freeze more than usual, try resetting the settings to factory settings. This is usually done by long pressing a combination of buttons, a description of which is in the instructions for a specific model Indesit.
Hidden functions of the service menu
In some Indesit models, there is access to the service menu where you can calibrate the sensors. However, getting there requires a complex sequence of presses (for example, holding down the Fridge and Freezer buttons at the same time for 10 seconds). Entering this menu unnecessarily may reset the factory settings, which will lead to incorrect operation of the entire unit. It is recommended not to go there without professional equipment.
Why the refrigerator freezes too much: the main reasons
If adjusting the knob or display does not help, and the food continues to become covered with frost, the problem may be deeper than a simple adjustment. One of the common reasons is refrigerant leak. Paradoxically, if there is a shortage of freon, the compressor can work almost non-stop, trying to gain temperature, which leads to severe freezing in those places where the refrigerant still remains, usually at the back wall.
Another common reason is a malfunction of the temperature sensor. If he “lies” and sends a signal to the board that the chamber is warm, the electronics will drive the compressor to the bitter end. In mechanical models, the thermostat itself may stick, not opening the circuit even with severe hypothermia.
It is also worth paying attention to the door seals. If they do not fit tightly, warm, moist air constantly enters the chamber. The refrigerator tries to compensate for the heat and wears out. As a result, a thick “coat” of ice forms on the back wall, which itself becomes an insulator, disrupting heat transfer and causing the unit to freeze even more in an attempt to break through this ice shell.
- 🔍 Sticking of the thermostat contacts leads to continuous operation of the motor.
- 🌬️ Impaired air circulation due to clogged ventilation holes.
- 🧊 A thick layer of ice on the evaporator prevents the correct reading of the temperature.
⚠️ Attention: If you notice that the compressor is running around the clock without breaks, and ice is forming on the back wall of the refrigerator compartment even with the minimum thermostat settings, this is a sure sign of a technical malfunction, and not a setting error.
The influence of the location of products and loading of chambers
Often the question of how to reduce the Indesit refrigerator is solved not by twisting the handles, but by correctly loading the shelves. Cold air is heavier than warm air and sinks. If you place a pot of soup right against the back wall or on the bottom shelf, it may freeze while the milk on the top shelf is warm. This creates the illusion that the equipment is not working properly.
You cannot place food close to the back wall of the chamber. This is where the evaporator is located (or the cold air supply channels in the No Frost system). The distance should be at least 2-3 centimeters. Violation of this rule leads to local hypothermia and freezing of packages to the wall.
Overfilling the refrigerator also plays a negative role. If there is no space for air flow between products, the temperature sensor may not have time to react to the actual situation in the chamber. As a result, “warm” and “ice” zones are formed. Try to load the chamber evenly, leaving the ventilation holes free.
Seasonal adjustment and external factors
The room temperature directly affects the operation of refrigeration equipment. In winter, when the apartment is cool (about +18°C), the refrigerator may turn on less often, but the duration of its operation may vary. In the summer, at an air temperature of +28°C and above, the heat transfer of the condenser deteriorates, and the compressor is forced to work more intensely.
In the summer, it is recommended to reduce the power of the refrigerator (put the knob closer to the minimum), since high ambient temperatures contribute to faster melting of ice with rare starts, but the cooling process itself is more difficult. However, if the refrigerator is located next to the stove, radiator, or in direct sunlight, no adjustment will help - it will work at its maximum capacity.
Check the gap between the back wall of the unit and the kitchen wall. It must be at least 10 cm. If the refrigerator is built into a niche, make sure that there is ventilation there. Overheating of the compressor due to poor airflow can lead to malfunctions in thermoregulation.
Frequently asked questions and answers (FAQ)
What to do if the thermostat knob spins endlessly?
If the knob does not have stops and spins in a circle without clicking, the thermostat mechanism may be broken. In this position, it cannot break the chain, and the refrigerator will freeze constantly. A part needs to be replaced.
Is it possible to completely turn off the freezer?
In most two-chamber refrigerators Indesit it is impossible to turn off the freezer independently, since the system is often tied to one compressor. However, some models have a "Vacation" mode, which turns off the refrigerator compartment, leaving the freezer to work.
Why do vegetables freeze in the bottom drawer?
Cold air goes down. If the thermostat is set to maximum (5 or Max), the temperature at the bottom of the chamber may drop below 0°C. Try reducing the power to 2-3 and not placing food close to the back wall.
How to understand that the thermostat is faulty?
Signs of a malfunction: the refrigerator does not turn off at all, or does not turn on at all, or the thermostat clicks are heard, but the compressor does not start. Another sign may be the lack of cold at maximum settings.
Does it need to defrost the refrigerator if it gets very cold?
Yes, if an ice crust has formed on the back wall, it must be removed. Ice acts as an insulator, which is why the temperature sensor does not “feel” the real cold and does not give the command to turn off the compressor. Defrosting for 12-24 hours often solves the problem.
