Sudden breakdown household appliances always come as an unpleasant surprise, especially when it comes to a refrigerator that stores food supplies. Indesit refrigerators are famous for their reliability and simplicity of design, which makes their repair quite accessible to a person with basic technical skills and a set of tools. Before calling a technician or buying a new unit, you should try to diagnose the problem yourself.
Independent troubleshooting allows you not only to save your budget, but also to extend the life of the device if you approach the matter responsibly. In this article we will look at the most common causes of breakdowns, methods for identifying them and ways to eliminate them.
First, you need to determine the nature of the malfunction: the refrigerator has stopped turning on, is not freezing, but the light is on, or is working non-stop without turning off. Understanding the symptoms is the first step to a successful restoring performance aggregation. Next, we will look at detailed action algorithms for each scenario.
Diagnostics of major faults
The first stage of any repair is an accurate diagnosis. Often, equipment owners mistakenly believe that the problem lies in complex electronics, while the reason may be trivial. Symptoms of failure may indicate different components: from the control system to the compressor. If the Indesit refrigerator hums but does not cool, this may indicate problems with refrigerant circulation or motor operation.
Pay attention to the indicators on the control panel if your model is equipped with an electronic module. Flashing lights or the appearance of error codes is a direct signal from the self-diagnosis system. In models without a display, the condition of the equipment can be judged by the sound of the operating compressor and the temperature in the chambers.
⚠️ Attention: If you hear clicks when you try to start, but the compressor does not start or hums for several seconds and goes silent, immediately unplug the device. Long-term operation in this mode can lead to burnout of the motor windings.
Check the integrity of the door seals. A loose fit allows warm air to enter, causing the unit to work without interruption, trying to maintain the set temperature. Rubber deformation or the sticking of crumbs are common causes of loss of tightness.
- 🔍 Check whether the light in the chamber is on when opening doors.
- ❄️ Assess the uniformity of cooling: is the back wall frozen or are there warm zones.
- 🔊 Listen to the sounds: a steady hum or intermittent clicks and gurgles.
Preparation tools and safety
Before you begin disassembling and repairing, you need to prepare your workplace and tools. Safety is priority number one, since you will be working with electricity and potentially hazardous substances. Make sure the floor in the room is dry and there is enough lighting to work with small parts.
You will need a basic set of tools that most home craftsmen will have. The lack of specialized equipment is not always an obstacle to carrying out restoration work medium complexity. The main thing is accuracy and consistency of actions.
☑️ Tools for repair
Be sure to disconnect the refrigerator from the power supply before starting any manipulations. Even if you are simply checking the contacts, the risk of electric shock if the insulation is damaged remains high. It is also recommended to defrost the chamber if you plan to work with the water drainage system or evaporator.
⚠️ Attention: Do not use an open flame to speed up defrosting or check the tightness of the system. This can damage plastic parts and cause a fire.
A multimeter is indispensable for diagnosing electrical circuits. With its help, you can check the integrity of the conductors, the resistance of the windings and the presence of voltage. Without this device, electronics repair turns into guesswork.
Replacing the start relay and thermostat
One of the most common reasons why Indesit refrigerator stops cooling is the failure of the start relay. This small element is responsible for starting the compressor engine. If the relay is faulty, the motor either does not start at all or operates intermittently, making characteristic clicking sounds.
To replace the relay, you need to gain access to the compressor, which is usually located in the lower rear part of the unit. Remove the protective cover, disconnect the wires and carefully remove the old relay from the motor contact group. Installation of a new element is carried out in the reverse order; it is only important to correctly orient the part according to the marking.
Another important element is the thermostat (thermostat). It is he who gives the command to turn the compressor on and off depending on the temperature in the chamber. If the refrigerator does not turn on at all or, on the contrary, works non-stop, causing severe icing, the problem may be in the mechanical thermostat.
Replacing the thermostat requires partial disassembly of the inside of the refrigerator compartment. It is usually hidden under a plastic panel or located inside the lampshade. Before installing a new sensor, make sure that its capillary tube is correctly laid in the allocated slot, otherwise the temperature readings will be incorrect.
| Symptom | Probable cause | Action |
|---|---|---|
| Clicks, but does not starts | Faulty starting relay | Replacing the relay |
| Does not turn on at all | Thermostat or wiring burnt out | Chain continuity, replacing the thermostat |
| Works without stopping | Freon leak or thermostat failure | Pressure diagnostics, sensor replacement |
| Severe icing | Faulty defrost heating element or timer | Checking the No Frost system |
Repairing the No Frost system
Indesit refrigerators with the system No Frost require a special approach to diagnostics. Unlike the drip system, here the air circulation is provided by a fan, and the heating element is responsible for defrosting the evaporator. If you notice that ice is freezing in the freezer compartment, and, on the contrary, there is heat in the refrigerator compartment, the defrost cycle is most likely broken.
First, check the fan. If it does not spin, cold air does not enter the upper chamber. The cause may be either jamming of the blades with ice or combustion of the fan motor itself. You can get to it by removing the back panel in the freezer compartment.
The second important element is the defrost heating element and the defrost sensor. If they fail, the evaporator becomes overgrown with a “fur coat” that blocks the air ducts. To check the heating element, you need to “ring” it with a multimeter: the resistance should be within normal limits (usually several hundred Ohms), and not go to infinity.
It is also worth checking the defrost timer or the electronic module that controls this process. In older Indesit models, there are often mechanical timers that wear out over time and stop switching between cooling and defrosting modes.
Problems with the compressor and refrigerant
The compressor is the heart of the refrigerator. If the diagnostics showed that the relay and thermostat are working properly, but the engine does not start or hums and turns off due to the thermal release, the problem may be in the compressoritself. A wedge of a mechanical part or an interturn short circuit of the windings are serious malfunctions that require replacement of the unit.
Replacing a compressor is a complex procedure that requires a vacuum pump to pump out the system and a gas station to pump in freon. At home, it is almost impossible to install hermetic sealing pipes and charge the refrigerant correctly without special equipment.
⚠️ Attention: An independent attempt to replace the compressor without vacuuming the system will lead to rapid failure of the new motor and contamination of the circuit with moisture. For such work, it is better to call a professional.
Another problem is a refrigerant leak. If the refrigerator runs quietly, the compressor is hot but there is no cold, and oil stains are visible on the tubes, depressurization has probably occurred. The leak is found using a leak detector or a soap solution, after which the soldering area is restored and the system is refilled.
Fixing problems with the electronic module
Modern Indesit models are equipped with electronic control boards. If an error lights up on the display or the equipment behaves inappropriately (it turns on, turns off, changes modes), it may be faulty electronic module. A common cause is the failure of capacitors or relays on the board due to voltage surges.
Visual inspection of the board may reveal swollen capacitors or blackened traces. In some cases, simple flashing or replacing burnt-out radio elements helps if you have soldering skills. However, a complete replacement of the control module is often required.
To replace the module, you need to remove the top cover of the refrigerator, disconnect the cables and install a new board. It is important to make sure that the new part matches the model of your unit, since the firmware may differ.
Do not forget that power surges are the main enemy of electronics. To protect expensive equipment, it is recommended to use voltage stabilizers or surge protectors with a good degree of protection.
FAQ: Frequently asked questions
Why does the Indesit refrigerator make a loud noise after repair?
Increased noise may be due to improper installation of the compressor (vibration is transmitted to the body), touching the tubes against each other a friend or the walls of a cabinet, as well as with the operation of a new motor that has not yet gotten used to it. Check the mounting bolts and rubber shock absorbers.
How long should the refrigerator cool down after defrosting before turning it on?
It is recommended to wait at least 2-4 hours after complete defrosting before turning it on again. This is necessary to stabilize the pressure in the system and evaporate residual moisture in order to avoid a short circuit or water hammer in the compressor.
Is it possible to replace the thermostat with an analogue from another model?
It is possible if the mounting dimensions, capillary tube length and temperature response range are the same. However, it is better to use original spare parts or high-quality analogues recommended by the manufacturer to avoid incorrect operation of the system.
What to do if there is water on the floor in the refrigerator?
Check the drainage hole in the refrigerator compartment - it could be clogged with debris. Clean it with a special wire or brush. Also make sure that the water collection tray above the compressor is intact and installed correctly.
