The situation when Indesit refrigerator the food in the upper compartment stops cooling is one of the most common problems faced by the owners of this equipment. Often this happens suddenly: you open the door, and it’s warm, like in the room, or the temperature is only slightly lowered, but not enough to preserve the food. In the lower part, where the freezer is usually located, everything may remain normal, which is confusing and makes you think about a “partial” breakdown.
The reasons for this behavior of the unit vary from a banal violation of operating rules to complex technical malfunctions of the No Frost system or drip defrosting. Italian brand, often assembled at factories in Russia, it is famous for its availability, but it also has weaknesses that appear after several years of active service. Understanding how your model works is the first step to successful restoration.
Do not panic and immediately call a specialist, since in some cases the problem can be diagnosed independently, saving a significant amount. However, it is important to soberly assess your strengths: if intervention is required with refrigerant or complex electronics, it is better to trust the professionals. In this article we will analyze the main scenarios of breakdowns, methods for identifying them and the procedure for action.
Violation of operating rules and simple causes
Before looking for complex technical faults, it is necessary to eliminate the elementary mistakes that many users make. Often the answer to the question why upper chamber it does not cool lies in the incorrect arrangement of products or settings. Check whether air circulation is blocked by a dense layer of food at the back wall or on the shelves. The air must circulate freely to distribute the cold evenly.
Pay attention to the position of the temperature regulator. In some models Indesit the scale may be knocked down, or the slider may be accidentally moved to the minimum cooling position. It is also worth checking whether the door closes tightly. If the rubber seal is worn out or dirty, warm air constantly flows inside, and the compressor simply does not have time to compensate for heat loss, especially in the hot season.
Another important point is loading warm products. If you put a pot of hot soup in the chamber, the temperature inside could rise sharply, and the system could take several hours to return to normal. At this time, the top shelf may appear to be “not working,” although the unit is simply restoring balance.
- 🧊 Check that the ventilation holes are not blocked by food.
- 🌡️ Make sure the thermostat is set to the middle position (usually number 3 or 4).
- 🚪 Inspect the seal door for cracks and loose fit.
⚠️ Attention: Never try to speed up the cooling process by opening the door more often or placing containers of ice inside - this will create additional stress on the compressor and can lead to its burnout.
If after checking all these points the situation has not changed within 24 hours, then the problem is of a technical nature and requires a more in-depth diagnosis.
Malfunctions of the thermostat (thermostat)
One of the most common reasons why Indesit refrigerator stops freezing in the upper compartment is the failure of the thermostat. This small device is responsible for turning the compressor on and off depending on the temperature inside the chamber. If its contacts are stuck in the “off” position or the temperature sensor is “lying,” the compressor simply will not start and the cold will stop being generated.
In models with mechanical control, you can determine the breakdown by turning the control knob all the way. If there is no characteristic click and the engine does not start, the thermostat may be faulty. In electronic models Indesit with a system No Frost the role of a thermostat is performed by a temperature sensor, which can also fail or its contact may oxidize.
Replacing a thermostat is a relatively simple and inexpensive procedure. However, it is important to choose an analogue with exactly the same characteristics, since different models have different operating temperature ranges. Installing an unsuitable part can lead to the refrigerator working without stopping or, conversely, turning on too rarely.
- 🔧 No click when turning the control knob.
- ❄️ The compressor is silent, although the chamber is warm.
- 🔌 Contact testing shows a break circuit.
If you notice that the refrigerator has started to operate in a strange mode (for example, it turns on and off too often), this may also be a sign of a “dying” thermostat, which has not yet completely failed, but is already working incorrectly.
Problems with the defrosting system (No Frost)
B refrigerators Indesit with a system No Frost the upper chamber may stop cooling due to the formation of a “snow coat” on the evaporator, which is hidden behind a plastic panel. If the automatic defrost system fails, ice blocks the ventilation ducts and cold air cannot physically enter the refrigerator compartment. In this case, the freezer can continue to work, since the evaporator is often located there or nearby.
The main culprits in this situation are the heating element (heater), defrost sensor or timer (in older models) / electronic control module (in new ones). The heating element may burn out, the sensor may stop sending a signal about the need for heating, and the control module may malfunction and not start the defrost cycle. As a result, every few days or weeks the ice does not melt, but grows until it completely blocks the air flow.
Diagnostics requires partial disassembly of the freezer. It is necessary to visually assess the condition of the evaporator. If it is covered with a thick layer of ice, and the fan (if your model has one) hums but does not blow, the problem is in the defrost system. Owners often notice this problem when they see water leaking from under the refrigerator, or when the food above begins to spoil.
It is important to understand that simply defrosting the refrigerator for 24 hours can temporarily solve the problem, but if the cause is a burnt heating element or sensor, the ice plug will form again within a week. Therefore, searching for a faulty element is mandatory.
- 💧 Water under the refrigerator or on the kitchen floor.
- 🌬️ The fan makes noise, but air does not flow into the chamber.
- 🧊 A thick layer of ice on the hidden evaporator.
⚠️ Attention: When checking the heating element and sensors, be sure to disconnect the refrigerator from the network! Working with live electrical components is life-threatening.
Refrigerant leakage and compressor malfunctions
The most unpleasant and expensive reason for the lack of cold in the upper chamber is a freon leak or compressor failure. If a microcrack has formed in the circuit No Frost or drip system, the refrigerant gradually evaporates. First, the refrigerator starts working longer to gain temperature, and then stops freezing at all or freezes only in the area of the evaporator (usually in the freezer), without reaching the top shelf.
The compressor is the “heart” of the refrigerator Indesit. If it hums but does not start, or, conversely, operates silently and does not heat up, the winding may be burned out or the piston may be jammed. In some cases, the compressor may work, but not create the required pressure due to wear of the valves, which also leads to insufficient cooling of the upper chamber.
It is almost impossible to determine a leak visually, since freon is colorless and odorless. Craftsmen use leak detectors or the method of washing the circuit. If you notice that the grille at the back of the refrigerator (condenser) is only partially cold or warm, and the unit itself works almost non-stop, this is a sure sign of a lack of refrigerant.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The refrigerator hums, but does not freeze | Freon leak / Capillary clogged | High (needs a technician) |
| The compressor does not start, there are no clicks | The start-up protection relay or thermostat is faulty | Medium (you can do it yourself) |
| The compressor hums for 5-10 seconds and turns off | The compressor is jammed or the relay is burned out | High (compressor replacement) |
| The freezer is freezing, the top is not | Problems with air circulation or sensors | Average |
Repairing the refrigerant circulation system requires special equipment: a vacuum pump, a filling station and soldering skills. It is practically impossible to repair the leak and refill it yourself freon with high quality.
Failures in the operation of the electronic control module
Modern refrigerators Indesit are equipped with electronic control modules that coordinate the work of all nodes. If the “brains” of the refrigerator fail, it may not correctly process signals from temperature sensors. For example, the module may “think” that the chamber is already cold enough and does not turn on the compressor, although in fact it is warm there.
Often problems with the module arise due to power surges or moisture ingress. In such cases, the refrigerator may behave strangely: blink indicators, make strange sounds, or simply refuse to follow commands. Sometimes a complete reset (reboot) helps, but if the chip is physically damaged, you will need to resolder the elements or replace the entire board.
Diagnostics of the control module requires special knowledge in electronics. At home, you can only visually inspect the board for blackening, swollen capacitors or traces of burning. If you see such damage, independent repairs without a soldering iron and a circuit are impossible.
- ⚡ Flashing indicators on the control panel.
- 🤖 Chaotic turning on and off of the unit.
- 🚫 Refusal to respond to changes in temperature settings.
If the problem is electronics, it is also important to check the wiring going from the module to the sensors and compressor. Oxidized contacts or frayed wires can create a false impression that the module itself is broken.
Clogged capillary pipe
Another technical malfunction typical of refrigerators of any brand, including Indesitis a clogged capillary tube. There is a very narrow section in the freon circulation system - a capillary, where a sharp drop in pressure occurs. Over time, oil oxidation products, moisture (turned into an ice plug) or debris left over from poor-quality previous repairs can get there.
When clogged, freon cannot circulate freely along the circuit. The pressure at the outlet of the compressor increases, but the refrigerant does not flow into the evaporator in the required volume. The result is the same as with a leak: the refrigerator works constantly, but there is no cold, or it appears only at the beginning of the circuit (in the freezer), not reaching the fridge compartment.
The blockage can be diagnosed by a characteristic sign: the filter drier (the metal cylinder next to the compressor) may be covered with frost or, conversely, be hotter than usual, and the tubes at the outlet of the compressor may be covered with frost. heat up unevenly. An accurate diagnosis is made after opening the system and checking the pressure.
Removing the blockage is a complex procedure that requires purging the system with nitrogen under high pressure, replacing the filter-drier and vacuuming. It is often easier and more reliable to replace the entire capillary tube, which only a qualified technician can do.
When you need to call a specialist
Despite the desire to save money, there are situations when independent repairs are not only useless, but also dangerous. If you have checked the thermostat, made sure that the defrosting system is working properly and the seals are intact, but no cold has appeared, most likely the problem lies in the “insides” of the unit.
Intervention in the refrigerant circuit requires a license and special equipment. Freon used in modern refrigerators, although not toxic in small quantities, can form toxic compounds when in contact with an open flame. In addition, improper charging can completely destroy the compressor.
⚠️ Attention: If you do not have experience working with refrigeration equipment and soldering tools, do not try to open the copper circuit yourself. This will lead to loss of warranty (if it is still valid) and higher cost of repairs in the future.
It is also worth contacting professionals if you need to replace the compressor. This is a complex process that includes reversing the pipes, evacuating the system and accurately filling with oil and freon. An error in the amount of oil or the presence of moisture in the system will lead to rapid failure of the new compressor.
And remember that the cost of calling a technician is often lower than buying a new refrigerator. Competent diagnostics will allow you to understand whether it is worth repairing your Indesit or is it easier to purchase a new model, especially if the unit has been in service for more than 10 years.
Frequently asked questions (FAQ)
How long does it take to defrost an Indesit refrigerator if it is covered in ice?
For complete and high-quality defrosting, especially if an ice plug has formed in the No Frost system, it is recommended to leave the refrigerator turned off with the doors open for at least 24 hours. A shorter defrosting may not melt the ice in hard-to-reach channels, and the problem will soon return.
Is it possible to operate the refrigerator if the upper chamber does not work, but the freezer is cold?
For a short time - yes, so that the food in the freezer does not disappear. However, prolonged operation in this mode is harmful to the compressor, which will wear out trying to compensate for the heat. In addition, the food in the upper chamber will quickly spoil. It is better to eliminate the cause of the breakdown as soon as possible.
Why did the refrigerator work after defrosting, but after a week stopped freezing on top again?
This is a classic sign of a malfunction of the components of the automatic defrosting system (heating element, defrost sensor or timer). Defrosting removed the ice plug, but did not eliminate the cause of its formation. Diagnostics and replacement of the faulty part is required.
What is the service life of the compressor in Indesit refrigerators?
The average service life of the compressor is 10-15 years, subject to normal operation and stable voltage in the network. However, overheating, frequent power surges and rare defrosting (for models with a drip system) can significantly shorten this period.
