The situation when your Indesit refrigerator ceases to cope with its direct responsibilities can take you by surprise. Products begin to quickly deteriorate, condensation appears in the chambers or, conversely, everything becomes covered with frost, and the unit hums almost without interruption. Italian equipment It is famous for its reliability, but even it has a service life and weak points that fail over time.
Before calling a technician or looking for a service center, it is necessary to conduct an initial diagnosis. Often the reason lies not in the breakdown of expensive components, but in improper operation or simple blockage. In this article, we will analyze in detail all the possible causes of decreased performance and help you understand whether you can fix the problem yourself.
Understanding how your model works Indesit will help you save time and money. We will consider both simple cases and complex technical malfunctions that require the intervention of professionals with specialized equipment.
Checking the tightness and integrity of the seal
The most common reason why refrigerator stops holding the temperature is a violation of the chamber's tightness. If warm air from the outside constantly enters the system, the compressor works hard, trying to compensate for heat loss, but does not have time to cool the volume to the specified values. First of all, carefully inspect rubber seal around the perimeter of the door.
There should be no cracks, cuts or places of deformation on the rubber. Over time, the material becomes tanned and no longer fits tightly to the body. Check whether products on the shelves or foreign objects are preventing them from closing tightly. It is also worth paying attention to the door hinges - if they are loose, the door may warp.
- 🧊 Carry out a test with a sheet of paper: clamp the sheet between the door and the body at different points; if it is easily removed, the seal is broken.
- 🔍 Inspect the corners of the seal for peeling or tears, which may not be noticeable at a quick glance.
- 🧹 Clean the folds of the seal from crumbs and sticky deposits, which often interfere with a tight seal fit.
If you find that the rubber has simply come off, you can try to glue it with special glue or heat it with a hairdryer to restore elasticity. However, in case of severe wear, only complete replacement of the seal will help. Do not try to lubricate the seal with vegetable oil or petroleum jelly - they destroy the structure of the rubber, which will lead to its rapid cracking. Use only silicone grease. replacing the seal.
⚠️ Attention: Do not try to lubricate the seal with vegetable oil or Vaseline - they destroy the structure of the rubber, which will lead to its rapid cracking. Use only silicone lubricant.
It is important to understand that even a microscopic gap negates the operation of the entire cooling system. In such cases temperature conditions it is disrupted throughout the entire chamber, and not just in one corner.
Faults in the defrosting system and frost
Many models Indesit equipped with a No Frost or drip defrosting. If the unit has stopped cooling, but the compressor is running, the problem may lie in excess ice on the evaporator. The ice coat works as a heat insulator, preventing cold from penetrating into the chamber.
In No Frost systems, a timer, heating element and defrost sensor are responsible for removing moisture and defrosting the evaporator. If one of these elements fails, the ice does not melt, but grows, blocking the ventilation ducts. The air stops circulating, and it becomes warm in the refrigerator compartment, although it can be very cold in the freezer.
How to understand that the problem is in the defrosting system?
If you defrosted the refrigerator completely (for 24 hours with the doors open), and after turning it on it worked fine, but a week later the situation repeated itself - the problem is definitely in the defrosting system components (heating element, timer, sensor).
Diagnostics often require partial disassembly of the rear wall of the freezer. Visually check to see if there are any “drifts” there. If the fan is jammed with ice and does not spin, cold air does not enter the upper chamber.
- ❄️ Complete defrosting of the unit for a day is the first step to test the hypothesis of a frozen evaporator.
- 🔌 Checking the defrost heating element with a multimeter for an open circuit.
- 🕰️ Diagnostics of the defrost timer, which could be “stuck” in the cooling mode.
If after defrosting the refrigerator worked like new, but after 5-7 days it stopped freezing again, then the automatic defrosting system is faulty. In this case, you need replacement of the burnt heating element or a faulty sensor.
⚠️ Attention: Never use sharp objects (knife, screwdriver) to chip ice inside the chamber. One awkward movement can puncture the thin evaporator tube, which will lead to an instant release of freon and expensive repairs.

Problems with the compressor and start relay
The heart of any refrigerator is compressor. If it does not start or works intermittently, there will be no cooling at all or it will be insufficient. Owners often notice that the engine hums for a few seconds, clicks and then goes silent. This is a classic sign of a malfunction of the starting relay or the engine itself.
The starting relay is a small part that provides an impulse to start the motor. If it burns out, the compressor cannot go from standby to operating mode. The problem may also be in the thermal protection relay, which turns off the motor when it overheats.
| Symptom | Probable cause | Necessary actions |
|---|---|---|
| Buzzing for 3-5 seconds, clicking, silence | Faulty starting relay | Replacement of the relay (you can do it yourself) |
| Motor is hot, does not start | Winding burnt out or jammed | Replacement of the compressor (only master) |
| Works continuously without shutting off | Freon leakage or wear | Pressure diagnostics and leak detection |
If the compressor runs continuously without shutting off, and at the same time it cools poorly, this may indicate a loss of engine performance or refrigerant leak. The motor tries to compensate for the lack of cold, working at the limit.
Replacing a compressor is a complex procedure that requires evacuation of the system and charging with freon. It is impossible to do this work independently without special equipment and skills.
Freon leakage and clogged capillary tube
These two problems often go hand in hand in the list of causes of poor cooling. Freon is the working fluid that circulates through the system, taking away heat. If its quantity decreases due to a microcrack in the circuit, the cooling efficiency drops in proportion to the leak.
Clogging of the capillary tube occurs due to moisture entering the system or wear products of the compressor oil. An ice plug or mud mass forms in a narrow channel, blocking gas circulation. As a result, the pressure in the system drops and no cold is produced.
The signs of these malfunctions are often similar: the compressor runs for a long time, the back wall of the refrigerator (where the condenser is located) remains only partially cold or warm. At the site of a blockage or the beginning of a leak, local cooling or, conversely, heating may be observed.
- 💨 A leak is often accompanied by a whistling sound in the place where the tube is damaged (if you listen carefully).
- 🌡️ When clogged, the filter drier may become covered with frost or, conversely, be hotter usual.
- 🔇 During these conditions, the compressor often operates quieter than usual due to the lack of load.
To eliminate a leak or blockage, you need to call a technician. He will find the location of the damage using a leak detector, seal it, replace the filter drier and fill the system with new refrigerant under the correct pressure.
Incorrect installation and operating conditions
Sometimes the answer to the question "why it doesn't cool well" lies not in the breakdown, but in the conditions in which the equipment is located. Refrigerator is a device that transfers heat from the inside to the outside. If something interferes with this process, efficiency decreases.
Check whether the unit is close to the wall or furniture. For normal operation of the condenser (grid at the back), a free flow of air is necessary. If the gap is less than 5-7 cm, the heat does not have time to dissipate, and the compressor overheats, going into emergency mode.
The influence of external factors is also critical. If the refrigerator is located next to a radiator, oven, or in direct sunlight, the cooling system cannot cope with the heat flow. In the summer, in hot rooms, the performance of any equipment decreases.
Another important point is the number of products. If you loaded a large amount of warm food you just bought, the refrigerator will work at its limit for several hours. Do not fill the chamber to capacity - this interferes with air circulation.
Failures in the electronic control module
In modern models Indesit with electronic control, the board is responsible for all processes. If it is out of order or “glitchy”, commands to turn on the compressor may not be received or given with errors. This is a complex malfunction that is difficult to diagnose without experience.
Symptoms may include random blinking of indicators, lack of response to buttons, or independent changes in temperature conditions. Sometimes the module requires flashing, but more often it requires replacement.
You can visually check the integrity of the contacts going from the board to the compressor and sensors. Oxidation or broken wires can simulate electronic failure. However, the board itself is the “brain”, and it is better to entrust its repair to the specialists of the service center.
⚠️ Attention: Power surges in the network are the main enemy of electronic modules. If you have unstable electricity, be sure to use a voltage stabilizer, otherwise repairing the board could cost half the cost of a new refrigerator.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator freeze only at the top, while it is warm at the bottom?
This is a classic sign of a malfunction of the No Frost system. Most likely, the evaporator in the freezer compartment is frozen, and the fan is not blowing cold air into the refrigerator compartment. Freon leakage is also possible.
How long should the refrigerator cool down after the first turn on?
The first turn on of a new or defrosted unit can take up to 2-3 hours to reach operating temperature. If after 4-5 hours the cold does not appear, then there is a malfunction.
Is it possible to replace freon in the refrigerator yourself?
No, this is impossible without special equipment (vacuum pump, pressure gauges, scales). In addition, it is necessary to find and eliminate the cause of the leak, otherwise the gas will come out again.
Why is the back wall of the refrigerator hot, but it does not freeze?
This may indicate a clogged capillary tube or a malfunction of the compressor, which circulates gas, but does not create the required pressure. Also check if there is too much food lying at the back wall inside the chamber.
