The situation when the refrigerator Indesit stops freezing often takes you by surprise, threatening food spoilage. Equipment owners notice that the ice in the freezer is melting, and the main compartment becomes too warm. The first step is to assess the scale of the problem: whether the compressor is working at all, whether the light inside is on and whether there are any extraneous sounds.
Sometimes the reason lies in a simple power outage or a malfunction of the thermostat. However, if you hear the hum of the motor, but there is no cold, or the unit is silent, a more in-depth diagnosis is required. It is important not to panic, but to consistently check the main components of the system.
In this article we will analyze typical malfunctions of models Indesit, from simple settings to serious compressor breakdowns. You will learn how to carry out an initial check and whether it is worth calling a specialist.
Primary diagnosis and simple causes
Before disassembling the equipment, exclude external factors. Often the problem is solved without calling a specialist. Check that the freezer door is securely sealed. If the seal is dirty or deformed, warm air enters the chamber and the refrigerator does not have time to freeze it.
Pay attention to the operating mode. Perhaps one of the household members accidentally switched the regulator to the “Vacation” or minimum cooling position. It is also worth checking whether the chamber is loaded too tightly with products, blocking the outlet openings for cold air.
⚠️ Attention! If you defrost your refrigerator but forget to wipe off the water or turn it on too early, it could cause a short circuit. Make sure the unit is completely dry before turning it on.
One of the common causes is a malfunction of the thermostat. If it is stuck, the compressor may not receive a signal to start. Try gently tapping it or turning the temperature control knob. Sometimes this helps to temporarily start the system.
Problems with the No Frost system and defrosting
Models Indesit with the system No Frost are susceptible to specific breakdowns associated with air circulation. If the fan in the freezer stops, cold air simply does not enter the main chamber. This is a common reason why the upper part works normally, but the lower part does not.
Another critical element is the defrost heating element. If it burns out, a “coat” of ice builds up on the evaporator, which blocks the operation of the fan. This can be seen visually if you remove the back wall of the freezer: you will see an ice compress.
- 🔌 Malfunction of the defrost timer —the mechanism does not switch the refrigerator to defrost mode.
- ❄️ Clogged drainage —the water does not drain out and freezes, blocking the channels.
- 🌀 Fan failure —lack of air circulation inside the chamber.
To check the heating element and timer, you will need a multimeter. Test the circuits for resistance. If the chain is broken, the part must be replaced. In models with electronic control, the defrost sensor could also fail.
Freon leak and problems with the compressor
If the compressor runs constantly without turning off, but there is no cold, there is a high probability of a refrigerant leak. Freon is a gas that circulates through a system of tubes. If the circuit is damaged (corrosion, mechanical stress), it evaporates and cooling stops.
Leakage symptoms: hot condenser (grid at the back), lack of cold in both chambers, sometimes a hissing is heard. Finding the leak on your own is difficult and requires special equipment. Refilling with freon is a task for professionals.
Another serious problem is the breakdown of the compressor itself. If the motor hums, clicks, but does not start, or operates with strong vibration and overheats, there may be an interturn short circuit or jamming of the piston group.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor does not turn on | The starting relay is faulty | Low |
| It hums, but does not pump | The compressor is jammed | High (replacement) |
| Works without stopping | Freon leak | Average |
| Weakly freezes | Clogged capillary tube | High |
Faulty start relay and thermostat
The start relay is a small unit attached to the side of the compressor. It is this that provides the impulse to start the engine. If the relay is burned out, the compressor will try to start, click and turn off due to overload.
Replacing the relay is not difficult: you need to remove the old unit, look at its markings (for example, PTC or RSIR) and buy an analogue. It is important to install it in the correct position, indicated by the arrow UP.
The thermostat (thermostat) is responsible for maintaining the temperature. If its contacts have oxidized or the bellows has lost its seal, the circuit does not close. In electronic models Indesit instead of a thermostat there is a temperature sensor, which is connected to the control board.
- 🔧 Dismantling — unplug the refrigerator from the mains before removing parts.
- 📏 Check —use the tester in dialing mode.
- 🛒 Selection —buy spare parts strictly according to the refrigerator model.
Often owners confuse the symptoms of a thermostat failure and a freon leak. In both cases, the refrigerator may not turn off or not turn on at all. Diagnostics using a pressure gauge will help to accurately determine the pressure in the system.
Errors in electronics and control module
Modern refrigerators Indesit are equipped with electronic control modules. Power surges in the network can damage the control board. In this case, the refrigerator may behave chaotically: turn on spontaneously, not respond to buttons, or display error codes.
If error indicators are on the display (for example, flashing temperature lights), decipher them according to the instructions. Codes may indicate a malfunction of sensors, a fan, or problems with communication between modules.
⚠️ Attention! Repairing electronic boards requires special knowledge and equipment. Do not try to solder the module yourself without experience, this can lead to complete failure of the equipment.
Sometimes the problem is solved by rebooting the system. Unplug the refrigerator from the outlet for 15-20 minutes. This will clear errors in the controller memory. If after turning on the problem recurs, diagnostics of the board is required.
☑️ Electronics diagnostics
When you need to call a technician
Not all breakdowns can be repaired with your own hands. If the diagnostics showed a freon leak, a clogged capillary system or a compressor malfunction, it is better to contact a service center. These works require evacuation of the system, soldering of pipes and charging with refrigerant.
Also, the help of a specialist is needed if you are not confident in your abilities when disassembling components. No Frost. Incorrect assembly can lead to damage to plastic parts or loss of tightness.
The technician will bring with him the necessary equipment: a pressure gauge station, a leak detector, a vacuum pump. This will allow for high-quality repairs and guarantee the work.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator hum but not freeze?
This may indicate a freon leak, a compressor failure, or a blockage in the system. It is also possible that the fan in the freezer does not start.
How to defrost the Indesit refrigerator correctly?
Disconnect the device from the mains, open the doors and leave for at least 24 hours. Do not use a hair dryer or knife to crush ice to avoid damaging the evaporator.
What does the flashing temperature indicator mean?
Flashing usually indicates an increase in the temperature in the chamber above normal. This may be a consequence of prolonged defrosting or a malfunction of the cooling system.
Is it possible to replace the compressor yourself?
Theoretically, it is possible if you have soldering skills and vacuum equipment. However, without experience, there is a high risk of damaging the new compressor or allowing moisture to enter the system.
