The situation when Indesit refrigerator works, but does not freezeis one of the most common and frightening for the owner. You hear the usual hum of the motor, see that the indicators are on, but inside the chambers the temperature remains at room temperature, and the food begins to deteriorate. This is a classic sign that the Indesit refrigerator is working, but does not freeze. does not try to start, here we are dealing with a more complex technical malfunction. compressor functions by trying to pump refrigerant, but the cooling process itself is disrupted at some stage of the cycle.
In contrast to the complete silence of the unit, when the engine does not even try to start, here we are dealing with a more complex technical malfunction. Cooling system it may be depressurized, clogged, or have control problems. Understanding why Indesit it stopped freezing when the engine is running will help you make the right decision: call a technician or try to eliminate the cause yourself.
Often owners ignore the first symptoms, believing that the equipment is simply “tired” or there is a power surge in the network. However, if the engine is running continuously without shutdowns, and there is no cold, this is a direct signal of a critical breakdown. In this article we will analyze in detail all possible options, from simple operating errors to complex mechanical defects.
Primary diagnostics and simple causes
Before you panic and look for a service center phone number, you should rule out basic errors. Sometimes Indesit refrigerator it doesn’t freeze because of trivial things that can be easily fixed in five minutes. First of all, check the tightness of the door. If the rubber seal is worn out, dirty, or the door is skewed, warm air constantly enters the chamber.
Under such conditions, the compressor works for wear, trying to compensate for heat loss, but cannot reach the desired temperature. It is also worth paying attention to the operating mode. If you have recently defrosted the unit or rearranged it, you may have turned it on too early. No Frost equipment and drip models require time to stabilize the oil and refrigerant pressure.
⚠️ Attention: If after turning on the refrigerator worked for a couple of hours and stopped freezing, but the motor continues to buzz, do not leave it in this state for a long time. Prolonged operation without cooling can lead to overheating and burning of the motor windings.
Check whether the food has blocked the ventilation holes inside the chamber. In models with the system No Frost cold air circulates through special channels. If the air path is blocked by boxes or bags, the sensors will show a normal temperature inside, but it will be warm in the depths of the chamber. Make sure that the “Super Freeze” mode is not constantly turned on, as this may interfere with the electronics operating algorithms.
Leak refrigerant: symptoms and consequences
One of the most common reasons why Indesit refrigerator it hums but does not get cold is a banal freon leak. The refrigerant circulates in a closed circuit, and if a microcrack appears in the system, the gas gradually evaporates. The compressor continues to work, trying to pump the already empty system, but heat exchange does not occur.
Leaks often occur in places where pipes are soldered, in the foamed part of the body or in the evaporator. It is difficult to notice this visually, since freon is colorless and odorless. However, there are indirect signs. For example, condenser grill the back of the refrigerator may be cold or lukewarm, whereas normally it should be hot.
If you notice that motor-compressor turns on more often than usual or works without stopping, and there is heat inside - this is a sure sign of a lack refrigerant. In such cases, a simple “refueling” will not help, since you first need to find the location of the leak, eliminate it, and only then fill the system with new gas.
- 🔍 Cold condenser: the rear grille does not heat up during prolonged operation.
- ❄️ Weak cooling: the food in the freezer is soft, the refrigerator compartment is warm.
- 🔊 Constant hum: the engine does not go into shutdown mode.
Is it possible to refuel the refrigerator on your own?
Independent refilling with freon is strictly not recommended without special equipment and skills. Incorrect amount of gas or presence of air in the system will cause compressor failure. Evacuation of the system and precise dosage by weight are required.
Clogged capillary tube
Another technical reason why Indesit stops freezing when the compressor is running is a clogged capillary tube. This is a very thin element of the system through which liquid freon is supplied to the evaporator. Over time, oil oxidation products, moisture, or small debris may accumulate in the system.
When the tube becomes clogged, refrigerant circulation stops or becomes insufficient. The compressor creates pressure, but freon cannot pass through the narrow opening. As a result, the evaporator does not freeze and no cold is generated. A characteristic sign of a blockage is overheating of the compressor and a specific sound of operation - often more strained than usual.
To eliminate this problem, professional cleaning of the system with nitrogen under high pressure is required. Sometimes it is necessary to replace the filter drier, which retains moisture and contaminants. If the system is not cleaned in time, the increased pressure can damage other components.
| Symptom | Freon leak | System clogged |
|---|---|---|
| Condenser temperature | Cold or barely warm | Hot, but unevenly |
| Compressor operation | Works without stopping | Works with overheating, may hum |
| Frost on evaporator | Absent or weak | Can only be at the entrance to the tube |
| Solution | Search for leaks and refill | Nitrogen purging, replacement filter |
Malfunction of the thermostat or sensors
In refrigerators Indesit thermostats (in mechanical models) or air sensors (in electronic models) are responsible for maintaining the temperature. If this element fails, it can send an incorrect signal to the compressor. For example, the sensor “thinks” that it is already minus 20 degrees in the chamber and does not give a command to cool, although it is warm inside.
Or the situation is the opposite: the thermostat does not open the circuit, and the motor is running constantly, but due to a failure in calibration, the cooling cycle does not start correctly. In models with electronic control malfunction of the defrost sensor it can cause the system to go into emergency mode, blocking the operation of the compressor or fan.
Diagnostics of these elements requires testing multimeter. A mechanical thermostat can be tested by immersing its sensing tube in cold water with ice - you should hear a click. Electronic sensors are checked for changes in resistance with temperature changes.
- 🌡️ Mechanical thermostat: often fails due to the exhaustion of the spring life.
- 💻 Electronic module: may incorrectly read readings from working sensors.
- 🔌 Contacts: oxidation of wiring contacts can also disrupt signal transmission.
Problems with the fan in the No Frost system
If you have a refrigerator Indesit No Frostthen the fan is responsible for circulating cold air. It is located in the freezer compartment and blows air through ducts into the refrigerator compartment. If the motor is running, there is freon, but there is no cold, the fan may have stopped.
The reasons for stopping can be different: freezing of the blades due to frozen ice, failure of the fan motor or broken wiring. In this case, evaporator will be covered with frost (which can be seen if you remove the back panel in the freezer), but this cold does not enter the main chamber.
The user can hear how compressor works, but inside it will be quiet, without the characteristic air noise flow. Sometimes the fan starts making noise, crackling or humming before stopping completely. It is necessary to defrost the refrigerator (at least 24 hours) and check the free movement of the blades.
⚠️ Attention: When checking the fan, be sure to unplug the refrigerator! Rotating blades can cause injury, and electric current can cause shock.

Mechanical breakdowns of the compressor
The most unpleasant option is when motor-compressor it hums, but does not start or runs idle. This may mean an interturn short circuit of the windings or, as is more often the case with the “works but doesn’t freeze” symptom, compression loss. The piston group inside the engine wears out, and it cannot create the necessary pressure for circulation of freon.
In such cases, the engine may emit a smooth hum, be warm, but not pump gas. Sometimes a metallic clanging or knocking noise is heard. If compressor overheats very quickly (in 10-15 minutes it becomes hot, it is impossible to touch it), most likely it requires replacement.
Repairing the compressor itself is impractical; it is replaced entirely. It is important to choose an analogue with suitable power and refrigerant. After replacement, the system must be evacuated and refilled with freon strictly according to the weight indicated on the nameplate.
- 🔨 Loss of compression: the engine is humming, there is no pressure in the system.
- 🔥 Overheating: the engine housing heats up in a short time.
- ⚡ Protection activation: the starting relay constantly clicks, trying to start the engine.
Frequent questions and answers (FAQ)
Why does the Indesit refrigerator freeze only in the freezer, but in Is the refrigerator compartment warm?
Most often this indicates a freon leak. The gas circulates in a circle, and if there is a shortage of it, the evaporator in the freezer is cooled first, and there is no longer enough cold to reach the main circuit. There may also be a malfunction of the damper that regulates the flow of cold air.
How long should the refrigerator cool down after switching on?
The normal time for refrigerators to enter mode Indesit is from 2 to 6 hours. If more than 8 hours have passed, the motor is running without stopping, and the temperature inside is above +10 degrees, this is a sign of a malfunction.
Is it possible to (use) a refrigerator if it does not freeze, but works?
For a short time - yes, so that the food does not go missing while you are waiting for the technician. But it is impossible to operate the equipment in this mode for a long time. The compressor operates in overload mode, which can lead to its complete combustion and more expensive repairs.
What to do if after defrosting the refrigerator turns on, but does not freeze?
If you defrosted it for less than 4-5 hours, perhaps the oil in the compressor did not have time to spread, or an ice jam remained in the system. Let the equipment stand turned off for another 10-12 hours. If it doesn’t help, the problem is deeper (leak or blockage).
