The situation when the upper compartment in a two-chamber refrigerator Indesit stops working is familiar to many owners of this equipment. This usually manifests itself in the form of melting ice, lack of cold, or, conversely, the formation of a snow coat when the lower compartment is working. The owner immediately faces the risk of food spoilage and the need for urgent intervention. The problem can lie either in a banal violation of operating rules or in a serious breakdown of the heat removal system or the compressor. Unlike No Frost systems, where the cold is distributed by a fan, in models with a drip system (Direct Cool) the upper chamber is an evaporator. This is where ice freezes and periodically thaws. If this process is disrupted, the cold stops flowing into the freezer. Diagnosing a malfunction requires a careful examination and understanding of the principles of operation compressor or heat removal systems.

Before calling a technician, it is worth conducting an initial diagnosis. Often the reason lies in little things that you can fix yourself in a matter of minutes. However, ignoring serious symptoms can lead to complete failure of the unit. In this article we will analyze the main breakdown scenarios and methods for eliminating them.
Checking settings and basic causes
First of all, it is necessary to eliminate the human factor. Sometimes users accidentally change the thermostat settings or forget to close the door tightly after defrosting. Make sure the temperature control is not set to “0” or “Min”. In some models Indesit with electronic control, the controller may have failed, requiring a reboot.
Pay attention to the tightness of the sealing rubber. If warm air from the room enters the chamber, the compressor will work continuously, trying to compensate for heat loss, but cannot cope with the load. This is a common reason why temperature in the upper compartment the temperature rises above normal.
⚠️ Attention: If you notice that the door rubber is cracked or has come away from the body, do not try to glue it with superglue. This will make the material rigid and completely break the seal. The seal needs to be replaced.
Check the chamber loading. If food is placed close to the back wall, it can block the flow of cold air or freeze to the evaporator, blocking the operation of the sensors. Leave a small gap at the back wall for circulation.
- 🔍 Check the position of the thermostat knob (should be at 3-4 notches).
- 🚪 Inspect the door for distortions and loose fit.
- ❄️ Make sure that the products do not touch back wall of the refrigerator.
- 🔌 Try unplugging the appliance for 15 minutes to reboot the electronics.
If after checking all these points the situation has not changed and the upper chamber still does not freeze, you will have to move on to a more in-depth analysis of the technical components.
Faults in the defrost system (for models No. Frost)
In refrigerators Indesit with the No Frost system, the upper chamber does not have its own evaporator - the cold is pumped there by a fan from a special compartment. If the ventilation is poor, the freezer will be cold, but the top will be warm. The most common reason is failure of the defrosting heating element Defrost heating element.
When the heating element burns out, the ice stops melting and accumulates on the evaporator. Sooner or later, a block of ice blocks the air ducts, and cold air simply cannot enter the upper chamber. Visually this may not be noticeable, since the evaporator is hidden behind a plastic panel.
How to check the heating element without disassembling?
Turn on the refrigerator and listen. If you hear the compressor humming, but the fan does not make noise or makes strange noises, it may be jammed with ice. Also a sign may be water under boxes of vegetables if the ice melts unevenly.
Another important element is defrost sensor. If he “lies” and does not give the command to turn on the heater, the same effect of blocking with ice occurs. Replacing these elements requires partial disassembly of the freezer.
It is also worth checking the fuse that is in the heating element circuit. It burns out when overheated, breaking the circuit. This is a protective mechanism that prevents fire, but it stops the entire defrost cycle.

Problems with the refrigerant and compressor
The most unpleasant situation is leak freon. Modern refrigerators Indesit use a thin tube foamed in the body, which can corrode over time. The symptom of a leak is classic: the compressor works constantly, without turning off, hums, but there is no cold anywhere, or it is very weak.
Sometimes a leak occurs in the foamed part of the housing (where the evaporator is located). In this case, repair is not economically feasible, since it requires opening the case and installing an external evaporator (“crying” on the back wall).
Another possible reason is clogged capillary tube. Oil and freon circulate in the system. Over time, a plug of paraffins or oil breakdown products may form in the tube. This blocks the flow of refrigerant. Sign of a blockage: the compressor is running, the condenser (grid at the back) is only partially hot or cold, but the freezer is warm.
⚠️ Attention: If you hear gurgling or hissing inside the refrigerator after the compressor stops, this is a sure sign of a leak or blockage. It is impossible to fix this on your own; you need to call a specialist with equipment for evacuation and refueling.
It is rare, but the compressor itself breaks down. It may hum, but not create the required pressure in the system. Or, on the contrary, it starts and immediately stalls due to the activation of a thermal relay.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor is silent, there is no light | No power, relay burned out | Low |
| Humming, does not turn off, no cold | Freon leak | High |
| Humming, no cold, condenser is warm | Capillary clogged | High |
| Ice in the freezer, warm at the top (No Frost) | Faulty defrost | Average |
Thermostat malfunction
The thermostat is the “brain” that decides when to turn on the compressor. If it fails, the refrigerator may “think” the temperature is normal and not start the cooling cycle. As a result, it becomes warm in the upper chamber and the food spoils.
In mechanical models Indesit the thermostat is a device with a capillary tube that is inserted into the evaporator. If the tube has moved or the contact in the thermostat itself has come loose, the circuit will not close. You can check it by closing the contacts directly (for diagnostics). If after this the refrigerator starts working, the problem is in the regulator.
In models with electronic control, the role of a thermostat is performed by temperature sensor (thermistor). It changes its resistance depending on the heat. If the sensor shows incorrect values, the control module will not give a command to start the compressor.
A common mistake is to try to adjust the screws on the thermostat itself. You cannot do this without a pressure gauge manifold and knowledge - you will reset the factory settings and the refrigerator will not work correctly.
Influence of the environment and operating conditions
Refrigerators Indesit, like most household appliances, are designed to operate in a certain climate class. If the appliance is kept in an unheated garage in winter or in a kitchen where the temperature drops below +10°C, it may stop freezing. The compressor simply will not start, since the sensor “thinks” that it is already cold.
The location of the unit is also important. If the refrigerator is located close to the wall or in a niche without gaps, the heat exchange of the condenser is disrupted. Overheating causes the system to wear out, but ineffectively.
The presence of heat sources nearby (battery, stove, direct sunlight) is also critical. In such conditions, the upper chamber may not cope with the load, especially in summer.
Make sure that there are the necessary gaps around the body: at least 5 cm on the sides, 10 cm at the back. This will ensure normal air circulation.
When you need to call a specialist
Independent repair is only possible if you replace the thermostat, heating element or sensors, if you have Skills in using a multimeter and a screwdriver. However, if we are talking about refrigerantevacuating the system or soldering tubes, you cannot do without professional equipment.
A master is needed if:
- 🛑 You find an oily stain on the floor or near the compressor (a sign leaks).
- 🛑 The compressor hums, but does not start, or starts for a couple of seconds and stalls.
- 🛑 There is a smell of burnt wiring or plastic inside the refrigerator.
- 🛑 After defrosting for a day, the cold did not appear.
An attempt to solder the tube yourself or add freon “by eye” often leads to final breakdown of the compressor, the repair of which costs more than a new refrigerator.
⚠️ Attention: Modern Indesit models use freon R600a (isobutane). This is an explosive substance. Any work related to breaking the tightness of the circuit should be carried out only by certified specialists in a well-ventilated area.
Prevention and care of the cooling system
To ensure that the upper chamber of your Indesit works properly for many years, follow simple rules. Regular defrosting (for drip systems) at least once every six months will prevent the formation of a thick crust of ice, which interferes with heat transfer.
Keep the back of the condenser grill clean. Dust and pet hair act as a heat insulator, causing the compressor to work overload. You need to vacuum the grill once a year.
Do not put hot food in the refrigerator. This creates a sharp jump in humidity and temperature, which leads to increased ice formation and stress on the components.
Following these recommendations will avoid costly repairs and keep your products.
Frequently asked questions (FAQ)
Why in the Indesit No Frost refrigerator is the upper chamber warm, but the lower chamber freezing?
Most likely, the air duct between the chambers froze due to a malfunction of the defrost system (the heating element, sensor or timer burned out). Ice blocked the flow of cold air. Defrosting is required (at least 24 hours) and replacement of the faulty element.
How long should the temperature be restored after defrosting?
Usually the refrigerator Indesit takes from 2 to 5 hours to reach operating temperature when empty. If you loaded the products at once, the time may increase to 10-12 hours. If during this time the cold does not appear, look for a malfunction.
Is it possible to operate the refrigerator if it does not freeze at the top?
For a short time - yes, if you transfer perishable foods to the working lower chamber. However, operation with a faulty thermostat or a leak can lead to combustion of the compressor, as it will work without stopping.
What does the flashing temperature indicator on the Indesit panel mean?
A flashing indicator (often red) indicates an increase in the temperature in the chamber above the permissible norm. This may be a consequence of recent defrosting, loading a large volume of warm food, or a breakdown of the cooling system.
