Modern household appliances of the brand Indesit are famous for their reliability, but even the highest quality units can malfunction over time. Primary diagnosis allows you to understand whether an urgent call for a technician is required or whether the problem can be solved yourself without resorting to expensive repairs. Owners often encounter situations when the device seems to be working, but the products begin to deteriorate or excess moisture appears on the walls.
Competent checking the refrigerator begins with careful observation of its behavior in normal operation. Do not rush to disassemble the case or access electrical components without first analyzing external signs. Understanding the basic principles of operation refrigeration circuit will help you quickly locate the fault and save time.
In this article we will analyze the main stages of checking Indesit refrigeration units, paying special attention to sound signals, temperature conditions and visual signs of malfunctions. A critically important indicator is the time of continuous operation of the compressor before the first shutdown, which normally ranges from 15 to 40 minutes depending on the load of the chambers.
Visual inspection and analysis of external signs
The first thing to do if you suspect a malfunction is to conduct a thorough external inspection. Pay attention to the condition sealing rubbers along the perimeter of the doors. If the rubber is cracked, deformed or simply dirty, the seal of the chamber is broken, and cold air freely escapes out.
Check for condensation or ice crust in places not intended for this. For example, in systems No Frost ice on the back wall of the working chamber indicates problems with defrosting or ventilation. In drip models, water should not accumulate under the vegetable drawers or leak out.
⚠️ Attention: If you notice swelling of the side walls of the case or a characteristic chemical smell, immediately unplug the device. This may indicate a refrigerant leak along with oil, which requires professional attention.
Inspect the back of the unit where the condenser is located (black grille). It should not be covered with a thick layer of dust, as this interferes with heat transfer. A dirty capacitor causes compressor to work with overload, which shortens its service life.
- 🔍 Check the integrity of the power cord and the absence of traces of melting on the plug.
- 👀 Inspect the floor under the refrigerator for oily stains or puddles.
- 🚪 Make sure that the door closes tightly and does not move when pressed lightly.
Diagnostics of temperature conditions
The main function of any refrigerator is to maintain the set temperature. To objectively evaluate the work Indesit it is not enough to simply touch the products with your hands. You will need a regular household thermometer capable of measuring negative values.
Place the thermometer in a glass of water in the center of the main chamber and leave for several hours. It is not recommended to open the door at this time. The normal range for food storage is considered to be from +2 to +6 degrees Celsius. If the readings fall outside these limits, it is necessary to adjust the settings.
In the freezer, the temperature should drop below -18 degrees. If you see that the food begins to thaw or, conversely, freezes, this is a signal of a failure in the control system or a freon leak. The electronic control unit in modern models may show an error code, but you should not trust it 100% without double-checking.
Frequent temperature fluctuations can be caused not only by breakdown, but also by improper operation. For example, loading hot products or opening the door too often in a hot room is confusing. Thermostat confused.
Checking the operation of the compressor and start relay
The heart of the refrigeration machine is the compressor. It is this that ensures the circulation of refrigerant throughout the system. In normal mode Indesit it works cyclically: it turns on, cools the chambers to the set temperature and turns off.
If the compressor hums continuously without turning off for hours, this indicates that it cannot reach the required temperature. The reasons can be different: from a banal freon leak to wear of the piston group of the motor itself. In this case, motor-compressor works for wear.
The opposite situation, when the engine starts for a few seconds, makes a click and goes silent, indicates a malfunction of the starting relay or motor windings. In this case, thermal protection often triggers, preventing the windings from burning out.
Checking the relay:1. Disconnect the refrigerator from the network.
2. Remove the casing from the back.
3. Carefully remove the relay from the compressor contacts.
4. Shake the relay: if you hear a ringing sound (like a coin), it means the contacts are broken.
⚠️ Attention: Before removing the relay or any electrical components, be sure to wait until the capacitors are completely discharged and make sure that the power cord is unplugged from the socket.

Assessment of the defrosting and ventilation system
In refrigerators Indesit with a system No Frost or Low Frost the serviceability of the defrosting system is critically important. If the evaporator becomes overgrown with ice, the cold stops flowing into the chambers, although the compressor may work properly.
The check begins with a visual inspection of the evaporator (located behind the back panel in the freezer). If you see a “coat” of ice there, you need to check the defrost heating element, defrost sensor and timer (or electronic module). In drip systems, the condition of the gutter for water drainage is important.
Clogged drainage hole is a common cause of puddles appearing under the refrigerator. You can clean it with a soft wire or a special brush. Also check the operation of the fan in the freezer: it should rotate freely and not make grinding sounds.
| Symptom | Possible cause | Check method |
|---|---|---|
| Ice on the back wall | Malfunction of the defrosting heating element | Ring the heating element with a multimeter |
| Fan noise | Ice freezing on the blades | Visual inspection after defrosting |
| Water inside the chamber | Drainage clogged | Blow out the drainage hole |
| Weak cold | Fan does not work | Check for air from channels |
How to defrost a refrigerator correctly?
To completely defrost the No Frost system, you need to disconnect the device from the network for at least 12-24 hours. Speeding up the process with a hairdryer can damage plastic parts and evaporator tubes.
Searching for refrigerant leaks and extraneous sounds
Freon leaks are one of the most annoying problems that are difficult to diagnose at home without equipment. However, there are indirect signs. If the compressor runs constantly, but there is no cold, and the condenser (grid at the back) remains cold or barely warm, there is a refrigerant leak refrigerant leak.
Listen carefully to the sounds. Gurgling, hissing, or whistling sounds may indicate where gas is escaping. Sometimes a leak can be detected visually by oily stains on the tubes or solder joints. Freon itself does not smell, but the oil that comes out with it has a specific odor.
Extraneous knocking and vibration can be caused by improper installation of the refrigerator. Make sure it is level and the adjustment feet are firmly in contact with the floor. Also check that the tubes at the back are not touching each other or the cabinet walls.
- 👂 A loud hum may indicate problems with the compressor shock absorbers.
- 💨 A whistling sound often indicates gas is escaping under pressure.
- 🔨 A metallic clanging sound at startup indicates a malfunction of the internal mechanisms of the motor.
⚠️ Attention: Self-filling the refrigerator with freon is prohibited and dangerous. To detect microcracks and restore the tightness of the circuit, a vacuum pump and a pressure gauge station are required.
Electronic diagnostics and error codes
Modern models Indesit equipped with a self-diagnosis system. If a malfunction is detected on the display or by flashing indicators, the device reports an error code. Deciphering these codes allows you to quickly identify a unit that requires attention.
For example, a flashing temperature indicator may indicate a malfunction of the temperature sensor in the chamber, and a combination of signals may indicate problems with the control module. However, it is worth remembering that electronics can fail due to power surges in the network.
To carry out a complete diagnosis of the electronic module, it is often necessary to connect a special tester. If you do not have the skills to work with electrical circuits, it is better to limit yourself to checking the voltage in the outlet and the integrity of the power cord.
Typical actions in the event of an electronics failure:1. Unplug the refrigerator for 15 minutes.
2. Turn it on again.
3. Check if the error has been reset.
4. If the error recurs, the sensor or module must be replaced.
Do not ignore repeated errors. Even if the refrigerator continues to freeze, a faulty sensor can lead to incorrect compressor operation cycle and its premature failure. Electronic module - a sensitive element that requires stable power supply.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator get very hot on the sides?
Heating of the side walls is a normal process for many models. In modern refrigerators, the condenser (heat exchanger) is often built into the side walls of the case. When the compressor operates, they release heat into the room. If the heating is moderate (up to 40-50 degrees), there is no need to worry. If the walls become hot to the point that it is impossible to touch, check the ventilation around the appliance.
How often do you need to defrost a refrigerator with No Frost?
The No Frost system involves automatic defrosting of the evaporator. It is necessary to forcefully defrost such a refrigerator rarely, about once a year, for general cleaning and disinfection. Frequent defrosting is not required and even undesirable, as it interferes with the stability of the system.
Is it possible to use an Indesit refrigerator on a balcony?
Operating the refrigerator on an unheated balcony is not recommended by the manufacturer. At temperatures below +10 degrees, the oil in the compressor thickens, which makes starting and lubrication difficult, and at temperatures below +5 the compressor may burn out. There may also be problems with condensation and the operation of the thermostat.
What to do if the temperature alarm indicator is on?
The indicator lights up if the temperature in the chamber has risen above a safe one. Check if the door is tightly closed. If you have just loaded a lot of warm food, give the refrigerator time (up to 24 hours) to settle down. If the indicator is constantly on when the chamber is empty, the sensor is probably faulty or there is a freon leak.
