The situation when your two-chamber refrigerator suddenly stops working always causes panic, because food supplies are at risk. Silence in the kitchen instead of the usual hum of the engine is the first sign of a serious problem. Owners of equipment Indesit often encounter this, and it is important not to rush to call a technician, but to carry out an initial diagnosis.
The first thing to do is to check the basic things: the presence of voltage in the outlet and the integrity of the power cord. Often the reason lies not in complex electronics, but in a simple failure or poor contact. If everything is in order with the electricity in the house, but the device is silent, you will have to look deeper.
In this article we will take a detailed look at the main components that could have failed. You will learn how to distinguish a breakdown thermostat from problems with the start relay, and understand when repairs are still possible on your own, and when professional intervention is required.
⚠️ Attention: Any work to disassemble the refrigerator Indesit carry out only after completely disconnecting the device from the electrical network. Electric shock can lead to serious injuries.
Primary diagnosis and external factors
Before grabbing tools, it is worth eliminating external factors that simulate a breakdown. Sometimes two-chamber refrigerator does not turn on because the protection has tripped or the contact has come loose. Carefully inspect the plug and socket: there should be no smell of burning or melted plastic.
Check whether the indicator light on the control panel is on, if provided by the model. The absence of light may indicate an open circuit. If you have a multimeter, check the voltage in the outlet itself - it should be stable.
It is also worth paying attention to the location of the device. If Indesit stands close to a wall or heating devices, it may overheat and go into protection mode. In this case, the compressor will not start until it cools down.
Problems with the thermostat (thermostat)
One of the most common reasons why Indesit refrigerator does not turn on is a malfunction of the thermostat. This sensor is responsible for monitoring the temperature inside the chambers and sends a signal to the compressor to start or stop. If it is “stuck” in the open state, the motor simply will not receive a command to start.
In mechanical models Indesit the thermostat is a device with a capillary tube that passes through the evaporator. Over time, the tube may lose its seal, the gas will evaporate, and the contacts will no longer close. In electronic models, temperature sensors are responsible for this, which can also produce incorrect data.
To check a mechanical thermostat, the “short circuit” method is often used. If, when connecting the contacts bypassing the regulator, the compressor starts, then the cause has been found. However, this method requires caution and an understanding of electrical circuits.
Symptoms of a malfunctioning thermostat are often complemented by the fact that the refrigerator either does not turn on at all or works without stopping, causing severe freezing. In two-chamber models, this can lead to the fact that the refrigerator compartment will be too cold, and the freezer, on the contrary, warm.
Malfunction of the compressor start relay
If you hear a quiet click, a hum, or an attempt to start the motor, which immediately stops, most likely the problem lies in starting relay. This small block is responsible for supplying a starting pulse to the motor winding. In refrigerators Indesit relays of the RT or RKT type are often used, which are subject to wear.
Inside the relay there is a coil and contacts. When heated, the bimetallic plate opens the circuit, removing the starting winding. If the mechanism jams or the contacts burn out, the compressor hums, but cannot start, after which the thermal protection is triggered.
Diagnostics of the relay is simple: you need to remove it from the compressor and shake it. If a ringing sound is heard inside or traces of carbon deposits are visible, the part requires replacement. This is one of the few operations that can be performed independently if you have basic skills.
☑️ Diagnostics of the start relay
It is important to understand that frequent starting attempts with a faulty relay can lead to combustion of the relay itself compressor. Therefore, if you notice a characteristic hum lasting 3-5 seconds followed by a click, it is better to stop using the device until the malfunction is eliminated.
Failure of the electronic control module
Modern two-chamber refrigerators Indesit (Push&Go, Smart series) controlled by sophisticated electronics. If the main control module fails, the device may completely stop responding to commands. This is the “brain” of the device, and its breakdown often requires qualified repairs.
Signs of a board malfunction can be different: random blinking of indicators, lack of response to buttons, or complete silence when there is voltage in the network. Sometimes the cause is a voltage surge in the electrical network, which breaks through the sensitive elements of the circuit.
In some cases, the module can be re-soldered by replacing burnt capacitors or tracks. However, a complete replacement of the unit is often required. Self-diagnosis here is difficult without special equipment and circuits.
⚠️ Attention: Repairing the electronic control module requires deep knowledge in radio engineering. Do not try to solder the board without experience, this may aggravate the situation and make recovery impossible.
It is also worth checking the cables and connections going to the module. Vibration can cause the contacts to move away, which leads to a loss of communication between the sensors and the “brain” of the refrigerator. Sometimes it is enough just to reconnect the connectors to make the system work.
Problems with the compressor and motor
The most expensive and serious option is failure of the engine itself compressor. If all previous checks (relay, thermostat, wiring) did not produce results, and the motor does not make any sounds or hums, but does not start even with a direct current supply, it is probably burned out or jammed.
Seizing of the piston group occurs due to lack of lubrication or moisture entering the system. In this case, the motor shaft cannot turn. Attempts to start such a motor only lead to strong heating of the housing and tripping of the protection.
Replacing a compressor in a two-chamber Indesit is a complex procedure that requires evacuation of the system and charging with freon. It is almost impossible to do this at home without scales.
Is it possible to restore a jammed compressor?
There is a method of “wedging” by applying high voltage, but it has a low success rate and is extremely dangerous. In 95% of cases, the unit needs to be replaced with a new one.
If the compressor is hot to the touch, but is silent, this is a bad sign. A cold and silent motor more often indicates a lack of power or a command from the electronics, which gives more hope for a successful and inexpensive repair.
Table of main symptoms and probable causes
For ease of diagnosis, we will create a summary table that will help you quickly navigate the problem. Compare the behavior of your Indesit refrigerator with the described signs.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| No light, no sound, silence | Problem with socket, cord or module | Low |
| Buzzing for 5-10 seconds, clicking, silence | The starting relay is faulty or the compressor is jammed | Average |
| Works non-stop, freezes weakly | Thermostat is faulty or freon is leaking | Medium/High |
| Indicators are flashing, no errors | Electronics or sensors failure | High |
As can be seen from the table, some problems can be solved quickly and cheaply, others require calling a technician with equipment. Accurate diagnostics allows you to save time and money without buying unnecessary spare parts.
When you need to call a technician
Despite the desire to save money, there are situations where independent repair Indesit is impractical or dangerous. If you need to open the refrigeration circuit to look for a freon leak, you cannot do without a special tool and a license.
A master is also needed if a compressor or electronic control module has burned out and requires reprogramming. A professional will be able to accurately determine whether it is worth repairing the old unit or whether it is easier to purchase a new one.
Do not forget that incorrect assembly or the use of non-original spare parts can lead to a fire hazard. If you are not confident in your abilities at any stage, it is better to stop.
⚠️ Attention: Opening the sealed circuit of the refrigerator without a license and special equipment is prohibited by the legislation of many countries due to the use of harmful refrigerants.
Prevention of breakdowns of the Indesit refrigerator
In order two-chamber refrigerator to serve for a long time and not fail at the wrong time, it is important to follow the operating rules. Regularly, at least once every six months, defrost the appliance and wash it to avoid the formation of an ice coat, which increases the load on the compressor.
Keep the condenser (grids at the back) clean. Dust and animal hair impair heat transfer, causing the motor to wear out. Vacuuming the back wall is a good habit that will prolong the life of your equipment.
Do not place hot foods in the chamber and do not load the refrigerator to capacity, disrupting air circulation. These simple rules will help avoid overheating and premature failure of important components.
