The situation when Indesit refrigerator ceases to perform its main function always catches taken by surprise. Products begin to deteriorate, and condensation or, conversely, an ice crust appears on the shelves. The owner is immediately faced with a panic question: what happened and is it possible to repair the unit yourself? Refrigeration equipment This is a complex mechanism where the failure of one part entails disruption of the entire system.
Modern models Indesit, be they classic two-chamber versions or systems No Frost, are designed according to a similar principle of refrigerant circulation. However, the reasons why the equipment stops freezing can be either trivial or requiring the intervention of a specialist. Often the problem lies not in the “filling” itself, but in operating conditions or external factors. In this article we will analyze in detail the main faults, methods for identifying them and an algorithm of actions.
It is important to understand that timely diagnosis helps to avoid expensive repairs. If you notice that temperature conditions it is broken, you should not immediately call a specialist. An initial inspection and checking simple parameters often allows you to fix the problem on your own. However, ignoring the symptoms can lead to a complete replacement of the compressor, which is not economically feasible.
Primary diagnosis and external factors
Before disassembling the back wall or looking malfunctions in the electrical circuit, it is necessary to exclude elementary mistakes. Users often forget that a refrigerator is not just a box with a motor, but a device that requires proper handling. If Indesit refrigerator is turned on, the light is on, but there is no cold, check the tightness of the door. Rubber seal over time it dries out, deforms or becomes dirty, which is why warm air gets into the chamber.
⚠️ Attention: If the seal is damaged or does not fit tightly, the compressor will work non-stop, trying to compensate for the loss of cold. This will lead to its rapid wear and failure.
It is also worth paying attention to the location of the unit. If it stands close to a wall or radiators, heat transfer is disrupted. Condenserlocated at the back does not have time to cool down, and the cooling efficiency drops. Make sure that the gap between the back wall and the furniture is at least 5-7 centimeters. Ventilation is a key factor in stable operation.
Check the thermostat settings. Perhaps one of the household members accidentally moved the handle or changed the settings in the electronic module. For models with mechanical control, the optimal position is “2” or “3”. In electronic models Indesit, the temperature in the main chamber should be about +4...+5°C, and in the freezer -18°C. Incorrect settings can simulate a breakdown.
Malfunctions of the thermostat and sensors
One of the most common reasons why the Indesit refrigerator does not freeze is the failure of the temperature sensors. It is these elements that “tell” the compressor when to turn on and when to stop. If the thermostat is “stuck” in the “off” position, the motor simply will not start and the chambers will become warm. In electronic models, this function is performed by The Indesit refrigerator does not freeze, it is out of order thermostat or temperature sensors. It is these elements that “tell” the compressor when to turn on and when to stop. If the thermostat is “stuck” in the “off” position, the motor simply will not start and the chambers will become warm. In electronic models this function is performed temperature sensors.
Diagnostics of a mechanical thermostat is simple: when plugged in, you should hear a click and start the compressor. If this does not happen, you can try to close the thermostat contacts directly (observing safety precautions!). If the motor starts working, it means that thermostat requires replacement. In models with the system No Frost defrost or evaporator sensors often fail.
- 🔍 Symptoms: The compressor does not turn on or, conversely, works without interruption, freezing food to the point of stone.
- 🛠️ Solution: Replacing the thermostat or calibrating the electronic sensor.
- 💰 Cost: Relatively inexpensive repairs that can be done independently if you have the tools.
It is worth noting that in modern models Indesit with electronic control an error is often found sensor NTC. It may give incorrect readings, causing the control module to “think” that the cold has already been reached and not start the compressor. Checking the resistance of the sensor with a multimeter will help you accurately determine its condition.
How to check the thermostat with a multimeter?
Unplug the refrigerator. Remove the thermostat knob and get to its contacts. Ring the contacts in the “on” position - the device should show “0” or emit a beep. In the “off” position, the circuit should be broken (infinity). If the device shows a break when turned on, the thermostat is faulty.
Problems with the defrost system (No Frost)
If you have an Indesit No Frost refrigerator and it has stopped cooling, while the compressor is working normally, the reason often lies in the defrost system. In such units, ice accumulates on the evaporator, hidden behind a plastic panel. It should turn on periodically Defrost heating element, melting this ice. If the heating element burns out, or the defrost timer fails, or the thermal relay is “stuck,” the ice does not melt.
Over time, the ice coat becomes so thick that it blocks the cold air circulation channels. As a result, the main chamber is warm, but the freezer may be colder than usual, but the food will still spoil due to the lack of convection. A characteristic symptom is swelling of the rear wall in the freezer.
| System component | Function | Symptom of malfunction |
|---|---|---|
| Defrost heating element | Heating the evaporator to melt the ice | The ice does not melt, the heating element is cold when turned on |
| Defrost timer | Switching "cooling/defrosting" modes | The refrigerator does not goes into defrost mode |
| Thermal relay (defroster) | Temperature control during defrosting | The heating element does not turn on or off |
| Defrost sensor | Signal to the module about the evaporator temperature | Incorrect data, defrost cycle failure |
To fix the problem, you need to defrost the refrigerator completely (at least 24 hours), remove the back panel in the freezer and check the integrity of the heating element and relay. Often it is enough to replace a burnt heating element to air circulation restored.
☑️ Diagnostics of the No Frost system
Faults of the compressor and starting relay
The heart of any refrigerator is the compressor. If Indesit refrigerator hums, clicks, but does not start, or is silent and does not respond to switching on, the problem may be in the start-up relay or the motor itself. A relay is a small plastic block that fits onto the compressor contacts. Its task is to start the motor and protect it from overloads.
It often happens that the relay simply “sticks” or burns out. In this case, the compressor tries to start, a loud click is heard, and it immediately stalls. Replacing the relay is a simple procedure: you need to remove the old element and install a new one that matches the compressor model. However, if after replacing the relay the situation does not change, and the compressor hums and does not start, it is possible that the windings or the piston group are jammed. an interturn short circuit windings or jamming of the piston group.
⚠️ Attention: If the compressor is very overheated (case temperature above 90°C) and has a characteristic burning smell, further attempts to start may be dangerous. In this case, professional diagnostics or replacement of the unit is required.
Two-compressor models Indesit have their own characteristics. In them, a separate motor is responsible for each camera. If only one chamber does not cool, but the second one is working properly, then the problem is localized precisely in the circuit of the non-working zone (compressor, thermostat or leak in this circuit). This simplifies troubleshooting.
Freon leak and capillary tube clogged
If the compressor runs constantly, but there is no cold anywhere, or it turns on for a short time and rests for a long time, while the condenser (grid at the back) remains cold or warm only at the entrance, most likely occurred refrigerant leak. Freon is a gas that circulates through the system. If a microcrack appears in the circuit (often in the foamed part of the housing or at soldering points), the gas escapes.
Without a sufficient amount refrigerant heat exchange is impossible. It is impossible to find a leak and refill the refrigerator on your own: you need to evacuate the system, search for leaks using special means (nitrogen, ultraviolet light) and an accurate dosage of freon. Attempts to simply “add gas” without eliminating the cause will lead to repeated breakdown in a week.
Another similar problem is clogged capillary tube. An ice or mud blockage may have formed in the system. The symptoms are similar to a leak: the compressor is hot, the condenser is cold, there is no cold. Sometimes “pushing” the system with nitrogen helps, but more often it requires cleaning or replacing the filter-drier and capillary.
When you need to call a specialist
Despite the desire to save money, there are situations when repairing an Indesit refrigerator with your own hands is impractical or dangerous. If you have checked all electrical circuits, made sure that the thermostats and relays are working, but the problem is not solved, most likely the problem is in the sealed circuit or compressor. Opening a sealed circuit without skills will result in damage to the product.
It is also worth contacting professionals if you need to replace the compressor. This is a labor-intensive process that requires soldering copper tubing, working with an open flame, and carefully evacuating the system. Incorrect soldering can lead to a fire or repeated failure of equipment in the shortest possible time.
- 📉 Savings: Independent repair is possible only by replacing attachments (relays, sensors, heating elements).
- ⚠️ Risk: Working with refrigerants requires a license and special equipment.
- 🛡️ Warranty: Intervention in the sealed circuit automatically voids the warranty.
Remember that a qualified technician will diagnose faster and give a guarantee for the work performed. In the case of refrigeration equipment not only knowledge is important, but also the availability of tools: a pressure gauge station, a leak detector, a vacuum pump.
Why does the Indesit refrigerator freeze only in the upper chamber?
Most often this indicates for a problem with the No Frost system (the evaporator in the freezer is frozen and does not allow air to pass through) or a freon leak. In two-compressor models, failure of the lower compressor or its thermostat.
How long should the compressor rest?
In normal operation, the compressor runs for about 10-15 minutes, followed by a pause (rest) lasting 15-25 minutes. If there are no pauses or they are too long, this is a sign of a malfunction.
Is it possible to use the Indesit refrigerator if it is noisy?
If the noise is not associated with vibration of the dishes or improper installation, but comes from the motor (knocking, grinding), it is better to stop using it. This may indicate damage to the bearings or compressor valves.
How often should you defrost a No Frost refrigerator?
The No Frost system does not require regular defrosting to remove ice, but it is recommended to carry out preventive defrosting and washing 1-2 times a year for hygiene and checking the operation of the fans.
