The situation when the refrigerator Indesit turns on and immediately turns off is a classic a symptom of a serious problem with the starting or cooling system. The owner usually hears a characteristic click, after which the motor stops, and after a while the cycle repeats. This condition is often called “cyclic startup”, and it indicates that the protective automation forcibly breaks the power circuit, preventing equipment failure.
Ignoring such a problem can lead to a complete replacement of an expensive compressor or burning out the wiring. Protection system reacts to current surges or overheating, so it is important to identify the root cause as soon as possible. In most cases, we are talking about mechanical wear of the trigger mechanism parts or a violation of the tightness of the circuit.
Before calling a technician, it is necessary to conduct an initial diagnosis to narrow the range of possible causes. Sometimes the problem lies in trivial things, such as power surges in the network, but most often the internal filling of the unit is to blame. Understanding the principle of operation will allow you to save time and money during repairs.
Malfunctions of the start relay and thermostat
The most likely reason why the refrigerator Indesit clicks and does not start lies in the start relay. This small unit is responsible for supplying voltage to the motor windings. Inside it there is a coil and a movable core, which, when current is supplied, must close the contacts. If the mechanism is worn out or burnt out, it cannot keep the circuit closed, and the motor stalls.
The second suspect is thermostat (thermostat). If its contacts are oxidized or stuck, the start signal may not be given correctly. In some models Indesit with electronic control, the role of a thermostat is performed by a sensor, but in classic lines it is a mechanical device. Incorrect temperature readings make the system think that the cold has already been reached, and it turns off the compressor.
What does a burnt relay look like?
Inside the plastic housing of the start relay, you will see blackened contacts or melted plastic. If you hear a ringing sound when shaking (like a broken light bulb), it means that the starting tablet or core is broken. In this case, the part must only be replaced.
Diagnostics of these elements requires caution. Before checking, be sure to disconnect the unit from the power supply. The relay is usually mounted on the side or rear of the compressor and can be removed with a simple movement. Checking the thermostat often requires testing with a multimeter in different temperature conditions.
Problems with the compressor and motor
If the starting relay is working properly, but the refrigerator Indesit buzzes, turns on and immediately turns off, the problem may be in the very heart of the system - the compressor. The engine may be in a “wedge” condition when the piston group is stuck due to exhaustion or lack of lubrication. At this moment, the starting current increases several times, and the thermal relay instantly opens the circuit.
Another common situation is interturn short circuit in the windings of an electric motor. With such a malfunction, the engine may try to start, make a dull hum and turn off. Continuing to try to turn it on in this case is dangerous, as this can lead to a fire in the wiring or complete combustion of the windings.
There is a method of “wedging” the compressor by applying increased voltage, but it requires special skills and equipment. At home, without experience, it is better not to experiment with high voltage, since the risk of getting an electric shock or completely destroying the unit is very high.
It is also important to check the condition of the wiring going to the motor. If the contacts are oxidized or the wires are frayed, the resistance in the circuit increases, which also triggers the protection. Visual inspection of the wires for melting and blackening is a mandatory stage of diagnosis.
Freon leak and clogged capillary
When the refrigerator Indesit turns on, runs for a few seconds and turns off, this may indicate problems in the refrigeration circuit. If there is an accident in the system, the compressor tries to pump gas, but due to its lack, the required pressure is not created. The motor idles, overheats and is turned off by the thermal relay. freon leak, the compressor tries to pump gas, but due to a lack of gas, the required pressure is not created. The motor idles, overheats and is turned off by a thermal relay.
A similar situation is observed when the capillary tube is clogged. Oil breakdown products or moisture can turn into an ice plug or mechanically block the refrigerant flow. The pressure at the outlet of the compressor rises sharply, the load on the engine increases, and the protection is triggered. This can be determined by its characteristic behavior: the unit may operate a little longer than usual before shutting down.
Signs of a leak or blockage are often accompanied by a lack of cold in the chambers. You may notice that the back of the refrigerator remains warm and there is no frost in the freezer. Oily spots sometimes appear at the leak site, as freon circulates along with the compressor oil.
It is almost impossible to repair a leak or break through an ice plug in a capillary on your own. It is necessary to evacuate the system, replace the filter-drier and refill with new refrigerant in compliance with the exact dosage. This is work for a specialist with professional equipment.
Failures in the electronic control module
In modern models Indesit with a system No Frost and an electronic display, the control module is responsible for starting the compressor. If triacs or other elements of the motor control circuit burn out on the board, the signal may be pulsed or interrupted. This causes the compressor to “blink”.
Voltage surges in the household network are often the cause of the failure. Refrigerator electronics are sensitive to changes, and the protective diodes on the board may fail, stopping the flow of current to the compressor relay. Visually, traces of burning or swollen capacitors may be visible on the board.
To diagnose the module, special test equipment is required. Unless you have the skills to read circuit diagrams and solder, it's best not to touch the board. Incorrect flashing or replacement of elements can lead to the refrigerator becoming uncontrollable altogether.
⚠️ Attention: If you notice a burning smell or melted plastic in the area of the electronic module, immediately unplug the refrigerator. Operation of such a device can lead to a short circuit and fire.
Sometimes the problem lies not in the board itself, but in the cables and connections. Oxidized connector contacts may give false signals. Checking the tight fit of all the chips is the first thing you need to do before replacing an expensive module.
Diagnostics and table of symptoms
To accurately determine the cause of the malfunction, you need to compare external signs. The behavior of the unit in the first seconds after switching on gives the key to understanding the problem. Below is a table that helps classify symptoms.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Click, buzz 2-5 seconds, silence | Fault start relay | Low (part replacement) |
| Strong hum, compressor heating | Motor jammed | High (compressor replacement) |
| Works 1-2 min, then turns off | Freon leak or blockage | Medium (requires a master) |
| Chaotic on/off | Faulty thermostat or board | Average (diagnostics with a multimeter) |
To carry out accurate diagnostics, you will need a multimeter. With its help, you can check the integrity of the compressor windings and thermostat contacts. The resistance of the windings must be within certain limits (usually from 10 to 30 Ohms for the working winding), and the resistance between the housing and the contacts must be infinite.
☑️ Primary check checklist
If you are not confident in your abilities, it is better to stop at a visual inspection. An attempt to disassemble a sealed circuit or replace a compressor without the skill of soldering copper pipes often ends in damage to the product. In such cases, calling a specialist will be more economically justified.
When you need to call a specialist
There are a number of situations when DIY repairs are impractical or dangerous. If the problem is related to sealed circuit (leakage, blockage, compressor replacement), a specialized tool is required: a freon filling station, a vacuum pump, a burner. Without them, it is impossible to restore functionality.
You should also call a technician if the situation has not changed after replacing the starting relay. This indicates a deeper problem inside the motor or in hidden areas of the wiring. Professional diagnostics will take less time than independent experiments with buying spare parts at random.
Do not forget that opening the components can break the factory seal, if it is still valid. Although this is rarely the case for older models, maintaining structural integrity is important for operational safety. Indesit This is rarely relevant; maintaining the integrity of the structure is important for operational safety.
⚠️ Attention: Freon used in refrigerators can be flammable (isobutane) or toxic at high concentrations. Independent depressurization of the system without an exhaust hood and special equipment is prohibited.
The cost of repairs often depends on the complexity of access to the components. In some models Indesit the compressor is filled with foam, and its replacement requires partial destruction of the housing, which makes repairs unprofitable. The technician will be able to assess the feasibility of restoration immediately after the inspection.
Why does the refrigerator turn on for 10 seconds and turn off?
Most often this is a sign of a faulty start relay or the initial stage of compressor jamming. The relay tries to start the motor, but due to high resistance or a mechanical obstacle, the current increases, and the thermal protection opens the circuit after a few seconds.
Is it possible to operate the refrigerator if it often turns off?
No, this will lead to overheating of the motor windings and a possible fire. In addition, the food in the chamber will begin to defrost, which will create a favorable environment for the growth of bacteria. The unit must be turned off until the reasons are determined.
How much does it cost to replace the start relay for Indesit?
The part itself is inexpensive (usually from 500 to 1500 rubles, depending on the model), but if you cannot replace it yourself, you will have to pay for the work of a specialist. Replacing the compressor will cost much more due to the cost of the unit and the work of refilling with freon.
Does the voltage in the network affect frequent shutdowns?
Yes, if the voltage in the network is below 190V or above 240V, the compressor may not start or work with overload. It is recommended to use a voltage stabilizer, especially in houses with old wiring or in rural areas.
