The situation when Indesit refrigerator ceases to properly cool food often takes you by surprise. The internal temperature may gradually rise, causing perishable food to spoil and create an unpleasant odor. The owner is immediately faced with a dilemma: call a technician or try to solve the problem himself by setting up the equipment.
Before you panic, it is worth noting that in many cases unit works properly, but the settings are lost or operating conditions are violated. Reducing the temperature inside the chambers may be required after loading a large amount of warm products or in the summer, when the ambient temperature in the room is high. However, if the equipment operates at the limit of its capabilities, and there is still not enough cold, this is a signal of deeper problems.
In this article we will look in detail at how to safely and effectively increase cooling capacity your device. We will look at action algorithms for different models, including No Frost systems and classic drip options. Understanding the principles of operation of the compressor and thermostat will help you quickly return the equipment to operating mode.
Diagnostics of the current temperature and symptoms
The first step should always be an accurate diagnosis. The visual determination of “warm” or “cold” is often erroneous. For an objective assessment, it is necessary to use an external thermometer placed in a glass of water on the middle shelf of the refrigerator compartment. The normal operating temperature for the main compartment is considered to be from +2 to +5 degrees Celsius.
If the thermometer shows values above +7 degrees, the cooling system is not functioning correctly. The temperature in the freezer should be below -18 degrees. If deviations are detected, pay attention to the operation of the compressor: it can work continuously without shutting down, or, conversely, turn on too rarely. Operation cycle is a key indicator of the state of the system.
It is also important to check for the presence of frost or ice in places not intended for this. For example, a “fur coat” on the back wall of the refrigerator compartment or uneven distribution of ice in the freezer may indicate defrosting problems or a refrigerant leak. These visual signs help narrow down the search for a malfunction.
⚠️ Attention: If the compressor runs around the clock without stopping, and the temperature does not drop below +10 degrees, there is a high probability of a freon leak or a compressor malfunction. Operation in this mode can lead to motor burnout.
Setting the thermostat and operating modes
The easiest way increase the cold is to set the thermostat correctly. In mechanical Indesit models, this is done by a rotary knob with numbers from 1 to 5 or from 1 to 7. Many users mistakenly believe that the number indicates degrees, but this is an index of cooling power. The higher the number, the more intense the compressor works.
To achieve the maximum temperature, you must turn the knob to the position of the maximum number (for example, 5 or 7). In electronic models, such as series Indesit Smart or EF, settings are made via the display. Here you set specific degrees. It is optimal to set the value to +3°C for the refrigerator compartment and -20°C for the freezer.
Do not forget about the “Super Freeze” function. This mode causes the compressor to run non-stop for a certain period of time (usually 24-48 hours), quickly freezing food and reducing the overall temperature in the chamber. After activating the mode (the indicator lights up), the temperature drops to a minimum. After a day, the function must be turned off manually or wait for an automatic reset, otherwise the products may freeze.
Use maximum power only when necessary or on hot summer days, when the heat flow into the chamber is high.
The influence of location and loading on cooling
Often the reason for insufficient cold lies not in a breakdown, but in a violation of operating rules. Air circulation Indesit should be free inside the refrigerator chambers. If the shelves are filled to capacity with products, cold air cannot be evenly distributed, creating “warm zones.”
Particular attention should be paid to the location of the equipment itself. If the refrigerator is located close to the wall or in a niche, the condenser radiator on the rear wall does not have time to give off heat. This results in the compressor not being able to effectively cool the freon. The minimum distance from the back wall to the wall of the room should be at least 5-7 cm.
- 🌡️ Do not place hot foods inside - this sharply increases the internal temperature and causes the compressor to work harder.
- 💨 Leave gaps between products for air flow, especially in models with the system No Frost.
- ❄️ Check that the ventilation holes inside the chambers are not blocked by packages or containers.
The condition of the sealing rubber on the doors is also critical. If the rubber does not fit tightly, warm air from the room constantly enters the chamber. You can check the tightness with a simple test: hold a sheet of paper in the door and try to pull it out. If the paper is pulled out easily without resistance, it means seal requires replacement or restoration.
☑️ Checking operating conditions
Problems with the defrosting and defrosting system
In Indesit refrigerators with the system No Frost and the drip system (“Crying Wall”), the defrosting process occurs automatically. However, if this cycle is disrupted, cooling efficiency decreases. In drip models, water should flow into the drainage hole. If it is clogged with debris or ice, the water freezes, forming an ice plug that blocks heat exchange.
In No Frost models, a timer, heating element and defrost sensor are responsible for defrosting the evaporator. If one of these elements fails, the evaporator becomes covered in ice. The fan stops pushing cold air into the chamber, and the temperature inside rises, although the compressor may hum continuously. Visually, this can manifest itself in the form of ice on the back wall inside the refrigerator compartment.
| Symptom | Possible cause | Action |
|---|---|---|
| Ice on the back wall | Faulty defrost sensor | Complete defrosting (24 hours) |
| Water on the floor | Drain clogged | Cleaning the tube with a brush |
| Fan noise | Ice on the blades | Defrosting and checking the heating element |
| No cold, compressor is hot | Freon leakage | Call a technician |
An independent solution to the defrosting problem often comes down to completely defrosting the refrigerator. It is necessary to disconnect the device from the network, open the doors and leave it for at least 24 hours (preferably for a day). This will allow the ice to completely melt and evaporate. After switching on, the equipment can work in normal mode, unless a critical electronic failure has occurred.
⚠️ Attention: Never try to break off ice with a knife or sharp objects! Damage to the freon channel or evaporator will lead to expensive repairs, which are often not economically feasible.
Why did the cold not appear after defrosting?
If after 24 hours of defrosting and turning on the temperature does not drop to maximum, the problem is deeper. The defrost heating element or defrost sensor has probably failed, or the circuit has broken. A refrigerant leak is also possible, which cannot be eliminated by defrosting.
Technical faults that reduce cold
If adjusting the settings and correct loading did not help, you will have to consider technical breakdowns. One of the common reasons for loss of cold in older Indesit models is refrigerant leak. Freon can escape through microcracks in the evaporator tubes, often hidden by the housing foamer. A sign of a leak is a hot condenser (grid at the back) and quiet operation of the compressor or its frequent starts.
Another common problem is failure of the thermostat (thermostat). This sensor tells the compressor when to turn on and when to turn off. If it is stuck in the off position or shows incorrect data, the compressor simply will not start or will work too little. Replacing the thermostat is a relatively simple and inexpensive procedure.
In models with electronic control, the control board may cause failures. Power surges in the network often damage triacs or other elements that control the compressor and fans. In such cases, the equipment may behave chaotically: turn on, hum, but not cool, or display errors on the display.
- 🔧 Clogged capillary tube: there is freon, but it does not circulate through the system. The system needs to be purged by a specialist.
- ⚙️ Compressor wear: the motor hums, but does not create the necessary pressure to compress the gas.
- 💨 Fan malfunction: in No Frost models, cold is not pumped into the chamber, staying behind the panel.
Diagnostics of these components requires special tools: pressure gauges, leak detectors and testers. You can independently check only the integrity of the electrical circuit of the thermostat or the presence of voltage at the compressor terminals, if you have the skills to work with a multimeter.
When you need to call a specialist
There is a clear boundary between do-it-yourself maintenance and professional repairs. If you have completed a complete defrost, checked the seals, set the regulator to maximum, but temperature does not drop below +10..+12 degrees during the day - it’s time to call service. Further experiments can only worsen the situation.
It is especially dangerous to ignore the smell of burnt wiring or a strong knock when starting the compressor. These are direct signs of an electrical malfunction or a mechanical wedge of the motor. Attempts to “reanimate” such a refrigerator by blows or repeated switching on can lead to a fire or complete failure of the unit.
Also, specialist help is needed if a compressor replacement or complex repairs are required. No Frost systems. These works require evacuation of the system, precise dosage of refrigerant and soldering of tubes in a nitrogen protective environment. It is impossible to do this efficiently at home without equipment.
Why does the Indesit refrigerator freeze only near the back wall?
This is a characteristic sign for a drip system or the initial stage of freezing of the evaporator in No Frost. In the first case, this is the normal operation of a “crying” wall, which periodically thaws. In the second, there is a signal that the defrosting system cannot cope, and the ice begins to block heat exchange throughout the chamber. Defrosting is required.
Is it possible to increase the cold by adding a second thermostat?
Theoretically it is possible, but in practice this is a gross interference in the electrical circuit. This can lead to incorrect operation of the standard automation, compressor overload and fire. It is better to use standard adjustments or replace a faulty original thermostat with a new one with similar characteristics.
How often do you need to defrost an Indesit refrigerator?
Models with the No Frost system do not require manual defrosting more than once a year (for hygiene). It is recommended to defrost drip models (“Crying Wall”) completely 2 times a year to clean the drainage and give the compressor a rest, although the automatic defrosts the evaporator regularly.
Does the temperature in the room affect the operation of the refrigerator?
Yes, directly. If the room is hotter than +30°C, it is more difficult for the Indesit refrigerator to transfer heat through the condenser. Efficiency decreases and the compressor runs longer. In such conditions, it may be necessary to additionally ventilate the room or install equipment away from heat sources (stove, radiators).
What to do if a strong smell appears after defrosting?
It could be the smell of mold from the drainage system or the smell of a burnt out motor. In the first case, washing the cameras with a solution of soda and vinegar will help. In the second, immediately turn off the device and check the back wall for melting. If there is a smell of burnt rubber from the compressor, operation is prohibited.
