Equipment owners Indesit often face the need to restore the functionality of the unit after several years of operation. The Italian brand has established itself as reliable, but even the most durable mechanisms are subject to wear. Independent repair of the Indesit refrigerator is possible in many cases if the malfunction does not require replacement of the sealed circuit.
Before calling a technician or disassembling the unit, it is necessary to carry out an initial diagnosis. Many problems, such as failure to start or constant running of the motor, can be caused by simple reasons: voltage fluctuations, clogged drainage, or incorrect installation of the thermostat. Understanding the structure of your model Indesit will allow you to save significant money on service.
In this article we will analyze the main components that most often fail and provide action algorithms for their restoration. Safety —the first rule: any work inside the electrical circuit is carried out only after the device is completely disconnected from the network.
Diagnostics of major faults
The first stage of any recovery is an accurate identification of the symptom. Refrigerators Indesit have characteristic signs of breakdowns that help narrow down your search. If the unit hums but does not cool, or, conversely, operates silently and is silent, the reasons will be radically different.
Listen carefully to the operation of the compressor. If you hear a click, followed by a hum that lasts 5-10 seconds, and then a click with silence again, this is a classic sign of a jammed piston group. If the motor makes no sounds at all, but the light in the chamber is on, the problem may lie in the thermostat or wiring. faulty start relay or jamming of the piston group. If the motor makes no sounds at all, but the light in the chamber is on, the problem may lie in the thermostat or wiring.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately stop trying to turn on and disconnect the device from the power supply. Further operation may lead to a fire.
Systems with No Frost are characterized by their own specific problems associated with the condensate drainage system and fans. Freezing of the channels or failure of the defrost heating element leads to the formation of a “fur coat” on the evaporator, which blocks air circulation. In such cases, the refrigerator may work, but the temperature in the chambers will be higher than normal.
Checking and replacing the thermostat
The thermostat is the “brain” that commands the compressor to turn on and off. In models Indesit with mechanical control, it is a device with a capillary tube extending into the chamber. If this element fails, the refrigerator either stops starting or works non-stop, causing icing.
To check the thermostat with a multimeter you need to get to its contacts. They are usually hidden under a plastic temperature control knob or behind a decorative panel inside the refrigerator compartment. Remove the handle and unscrew the mounting screws to gain access to the sensor body.
- 🔌 Disconnect the wires from the thermostat terminals, having previously photographed their location.
- 🔧 Connect the two main wires directly to each other (using jumper or twist).
- ❄️ If after closing the compressor starts, it means that the thermostat is faulty and requires replacement.
Replacing the element does not require special skills, except for accuracy when working with the capillary tube. The new part must be installed in the seat, being careful not to bend the thin sensor tube. After installation, check the operation of the unit in test mode.
Faults in the start relay and compressor
The most expensive part of the refrigerator is motor-compressor. However, often the culprit for stopping work is a small part called starting relay. It is located in a black casing at the back of the unit, directly on the motor housing. Inside the relay there is a posistor, which is destroyed over time due to thermal loads.
To check the relay, it must be removed. It is usually held on by a bracket or plastic clips. Shake the part near your ear: if you hear ringing or knocking of ceramic fragments inside, the posistor is broken. This is the most common reason why the refrigerator Indesit buzzes for a few seconds and turns off.
☑️ Diagnostics of the start relay
If the relay is working, but the compressor does not start or is humming “pull-in” may have occurred water hammer or wear of the mechanical part of the motor. In this case, replacing the relay will not help. It is also worth checking the motor windings for inter-turn short circuits, although this requires more in-depth knowledge of electrical engineering.
Is it possible to repair the compressor?
Independent repair of the compressor itself (replacing valves, rewinding) at home is impossible due to the need vacuum system and special tools. If a malfunction of the motor is confirmed, it is replaced entirely.
Problems with the No Frost system and defrosting
Refrigerators Indesit with the system No Frost are convenient in that they do not require manual defrosting, but their design is more complex. The key elements here are the evaporator, fan, defrost heating element and temperature sensors. If you notice that a block of ice is freezing in the freezer compartment, but it is warm in the refrigerator compartment, the melt water drainage channel is most likely clogged or the heating element is out of order.
For diagnostics, you need to dismantle the back panel in the freezer compartment. The evaporator is hidden under it. If it is completely covered with ice and the fan does not spin or spins with difficulty, the defrost system has not worked. Check the integrity defrost heating element by continuity: it should show a resistance in the region of 200-400 Ohms.
| System element | Fault symptom | Checking method |
|---|---|---|
| Defrost heating element | Ice on the evaporator | Resistance testing |
| Defrosting sensor | The heating element is not turns on | Resistance measurement at different temperatures |
| Fan | Noise, lack of cold | Visual inspection and rotation check |
| Drain hole | Water at the bottom of the chamber | Visual inspection and cleaning |
Often the problem lies in the drainage hole, which becomes clogged with crumbs or mold. Water stops flowing into the compressor pan and freezes, forming an ice plug. You can clean the channel using a soft wire or a brush, pouring a little warm water into it.
Eliminating refrigerant leaks and replacing the filter
If after defrosting the refrigerator turns on, runs for a day, and then stops cooling, and there is no characteristic heating on the rear grille (condenser) - is evident freon leak. Modern models Indesit often use a foamed evaporator located inside the walls of the housing. Replacing it at home is extremely difficult and economically unfeasible.
However, if the leak occurs in an accessible place (for example, in a door heating circuit or on visible copper pipes), repairs are possible. This requires equipment: a vacuum pump, a pressure gauge station and a supply of refrigerant. It is impossible to perform this operation independently without skills and tools.
⚠️ Attention: Freon is a gas that requires professional disposal. It is prohibited by environmental regulations to release it into the atmosphere. Work on the sealed circuit must be carried out by a certified technician.
The refrigerant always changes along with the refrigerant charge filter drier. This is a small cylinder on the back of the refrigerator that removes moisture from the system. If the filter is not replaced, moisture will freeze in the capillary tube, and the refrigerator will stop working again after a short time.
Replacing the seal rubber and door adjustment
Over time, the sealing rubber on the doors Indesit loses elasticity, cracks or deforms. This results in warm air constantly entering the chamber. The compressor is forced to work non-stop, trying to compensate for heat loss, which leads to its overheating and increased energy consumption.
You can check the tightness with a simple sheet of paper. Clamp the sheet with the door around the perimeter: if it pulls out too easily or falls out, the seal does not fit. In some cases, rubber can be restored by heating it with a hairdryer or boiling water to restore its volume. But if there are breaks, a complete replacement of the seal is necessary replacing the seal.
- 🚪 Remove the old rubber by unscrewing the screws or pulling it out of the groove (depending on the model).
- 🧼 Thoroughly degrease the surface of the door where the new one will be attached seal.
- 🔨 Install new rubber, starting from the corners, and make sure that the magnetic tape fits snugly around the entire perimeter.
Also check the door hinges. If the door is warped, it will not close tightly even with a new seal. Loosen the hinge mounting bolts, level the door and tighten the fastenings. For models with Lower Freezer (freezer at the bottom), it is important to monitor the horizontal position of the entire body.
Frequently asked questions about repairs (FAQ)
Why does the Indesit refrigerator make a loud noise after installation?
A strong hum can be caused by improper installation. Make sure the refrigerator is level and not touching walls or furniture. Check the transport bolts on the compressor (if any) - they need to be unscrewed. A vibrating condenser at the back may also hum if it touches the tubes.
How to defrost an Indesit No Frost refrigerator?
The system No Frost does not require regular defrosting, but once every year and a half it is recommended to turn off the device for 10-12 hours for complete drying and hygiene. This will help clean hidden channels and remove odors. Complete defrosting is also necessary before a long departure.
What does a flashing temperature indicator mean?
A flashing indicator on the control panel Indesit usually signals that the temperature in the chamber has risen above the permissible norm. This may happen after loading a large amount of warm food or if the cooling system is faulty. If the blinking does not stop after several hours of operation, diagnostics are required.
Is it possible to reverse the Indesit refrigerator door to the other side?
Most models Indesit allow you to reverse the door. For this purpose, holes for hinges are provided on the opposite side of the case, and the kit often includes plugs for old holes. The process requires care, since the doors are heavy and may have fragile fastening elements.
