The situation when the refrigerator Indesit stops freezing always takes you by surprise and requires an immediate response, since there is a risk of food spoilage. Owners often panic, but in most cases the problem lies in trivial things that can be fixed on their own without an expensive call to a specialist. The primary task is to understand the scale of the problem: whether the cold has completely disappeared or has become weaker, whether the compressor is working, and whether there are any extraneous sounds.
Modern models, such as Indesit DF 520 or Indesit C 138 G, are equipped with complex electronics and systems No Frost, which makes them vulnerable to voltage surges and improper operation. If the unit is plugged in, the indicator lights up, but the temperature inside the chambers does not drop below room temperature, this indicates a violation of the cooling cycle. It is important not to try to immediately disassemble the unit, but to carry out initial diagnostics so as not to aggravate the situation.
In this article we will analyze in detail the algorithm of actions when a malfunction is detected, consider typical compressor breakdowns Indesit and give clear instructions for checking the main components. You will find out when you can repair the equipment yourself, and in which cases the intervention of a professional with specialized equipment is required.
Primary diagnostics and power check
Before looking for complex technical faults, you need to make sure that the refrigerator is receiving electricity at all. Sometimes the problem is trivial: the power cord may have come loose, the machine in the panel may have been knocked out, or the light bulb in the socket may have burned out, creating the illusion of working equipment. Check whether the power indicator on the control panel is lit Indesit and whether the compressor makes a characteristic hum or clicking noise when starting.
Pay attention to how the thermostat or electronic control module behaves. If you turn the temperature control and there is no response, there may be a problem with the controller. In models with mechanical control, the click of the thermostat should be heard when turning the knob from the extreme position.
⚠️ Attention: If you hear the hum of the motor, but it does not start, and after a while there is a click and the hum stops - under no circumstances leave the refrigerator plugged in. This is a sign that the starting relay or the compressor itself are in critical condition, and further operation will lead to their complete burnout.
Check the tightness of the door. If the seal (cuff) is worn out or dirty, the cold will escape, and the compressor will work non-stop, trying to compensate for the heat inflow, but in the end it may overheat and shut down due to thermal protection. A simple test with a sheet of paper will help identify leaks: hold the sheet with the door and try to pull it out - if it comes out too easily, the seal is broken.
Analysis of the operation of the compressor and start relay
The heart of any refrigerator is compressor. If the refrigerator Indesit stops freezing, first of all listen to the operation of the motor. In good condition, it works cyclically: it turns on, gains speed, works for a while and turns off. If the motor is completely silent, although the indicators are on, the thermal protection may have tripped or the starting protection mechanism has failed.
The starting relay is a small part that is attached to the side of the compressor. It is this that provides the impulse to start the engine. In refrigerators Indesit there are often relays with a posistor, which eventually fail. If, when you turn on, you hear a series of quick clicks, but the motor does not start, or there is one loud click and silence, the problem most likely lies here.
To diagnose the relay, you need to remove it and shake it. If a rattling sound is heard inside, it means the posistor has crumbled and requires replacement. This is one of the most common reasons why equipment stops cooling, and it can be solved by purchasing a new part that matches the compressor model.
☑️ Compressor diagnostics
It is also worth paying attention to the temperature of the compressor housing. If it is hot (it is impossible to hold your hand), but there is no cold, this may indicate an interturn short circuit of the windings or a loss of performance of the piston group. In such cases, repairs are often not economically feasible, and replacement of the entire unit is required.
Problems with the No Frost defrosting system
In models with the system No Frost, such as the popular series Indesit EF or Indesit DS, a frequent cause of lack of cold there is a malfunction of the evaporator defrost system. If the defrost heating element, timer or defrost sensor fails, a “coat” of ice grows on the evaporator, which blocks the circulation of cold air through the chambers.
Visually this can manifest itself as follows: the back wall in the freezer is covered with ice, the fan is humming, but no air enters the refrigerator compartment. In this case, the compressor can work constantly, trying to reach the set temperature, but due to the ice jam this is impossible. In such cases, complete defrosting of the unit is often required within 24 hours.
| System element | Fault symptom | Check method |
|---|---|---|
| Defrosting heating element | Ice accumulation on evaporator | Test resistance (should be 200-600 Ohm) |
| Defrost sensor | The heating element does not turn on or heats constantly | Checking resistance at different temperatures |
| Defrost timer | The refrigerator does not go into defrost mode | Checking contacts and mechanical movement |
| Fan | Noise, lack of air circulation | Visual inspection of the blades and checking rotation |
If after complete defrosting (at least 24 hours with the doors open) the refrigerator began to freeze normally, but after a week or two the situation repeated itself, it means that one of the elements of the defrost circuit is faulty and requires replacement. Ignoring this problem will result in ice reaching the compressor, which will cause its breakdown.
How to defrost a No Frost refrigerator correctly?
To completely defrost the No Frost system, it is not enough to simply turn off the refrigerator at night. It is necessary to open all doors, remove shelves and drawers, and leave the unit in a warm room for at least 24 hours. Only during this time will the ice in the hidden channels of the evaporator have time to completely melt and drain. It is strictly forbidden to speed up the process with a hairdryer or hot water - this can damage the plastic and electronic components.
Freon leak and capillary system blockage
One of the most unpleasant situations is a refrigerant leak (freon) or capillary tube blockage. In refrigerators Indesit leaks often occur in places where tubes are sealed, in the foamed part of the body (condenser) or in the evaporator if it was damaged during defrosting with a sharp object.
Signs of a leak or blockage are:
- 🧊 The compressor works constantly, without turning off, but there is no cold.
- 🌡️ The condenser grille at the back of the refrigerator remains cold or warm only partially.
- 💨 No characteristic hissing is heard from the freon outlet hole in the freezer (when blockage).
- 📉 The temperature in the chambers gradually rises to room temperature.
It is impossible to eliminate a leak or blockage on your own, since this requires evacuating the system, replacing the filter-drier and charging with refrigerant under pressure. Attempts to simply “add freon” without looking for a leak will only give a temporary effect, after which the gas will escape again.
⚠️ Attention: If you find an oily stain under the refrigerator or in the place where the pipes are soldered, this is a sure sign of depressurization of the system. The operation of such a unit is prohibited, since the oil released along with freon can cause a short circuit or fire.
It is important to understand that modern refrigerators are charged with mixed refrigerants, and simple refilling “by eye” is impossible. Requires accurate gas weighing and the use of specialized equipment. If the technician offers to simply “pump up” the gas without evacuation, this is a sign of unprofessionalism.
Faults in the electronic control module
Modern models Indesit, especially with a display on the door, are controlled electronically. module. Voltage surges in the network, moisture ingress when washing the floor, or manufacturing defects can lead to board failure. In this case, the refrigerator may behave inappropriately: turn on and off spontaneously, not respond to buttons, show error codes.
Frequent symptoms of module failure:
- 🔌 All indicators light up simultaneously or blink in a chaotic manner.
- ❄️ The compressor does not start, although the thermostat requires cold.
- 🔊 The fan hums, but does not spin, or works intermittently.
- 📟 The display shows an error code (for example, F04, F06, etc.).
Board diagnostics require skills in working with electronics and the availability of circuits. You can often visually notice swollen capacitors or traces of burning on the tracks. However, even if the board is visually intact, the microcontrollers or triacs that control the loads could burn out.
Sometimes the problem is solved by resetting the errors (“rebooting”) the refrigerator: unplug it for 15-20 minutes, then turn it on again. If the error was a software glitch, the unit may work. If the problem persists, it is necessary to replace the module or repair it in a service workshop.
When you need to call a technician
Despite the desire to save money, there are situations when self-repair is not only useless, but also dangerous. If you have checked the power supply, relays and defrosting, but the refrigerator Indesit still does not freeze, professional intervention is most likely required.
Calling a specialist is required in the following cases:
- 🛠️ Replacement of the compressor or refilling with freon is required (a licensed technician is required and equipment).
- 🔌 There is a suspicion of a voltage breakdown on the case (a tingling sensation is felt when touched).
- 💧 A refrigerant leak has been detected in the foamed part of the case.
- 🧩 The electronic control module of complex logic is faulty.
A professional technician will conduct a complete diagnosis using a pressure gauge manifold and a leak detector. This will allow you to accurately determine the cause: be it a microcrack in the circuit or a loss of motor performance. Qualified repairs will extend the life of your refrigerator for years, unlike artisanal methods.
Why can repairs from an official dealer be more expensive?
Official service centers often use original spare parts and comply with strict standards, which increases the cost of work. Private craftsmen can offer a lower price using refurbished components or analogue parts. The choice depends on the age of the refrigerator: for new equipment, official service is better; for old equipment (over 7-10 years old), repairs from a private specialist or purchase of a new unit are often economically justified.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator only freeze in the freezer, but is it warm in the refrigerator?
Most often this indicates a malfunction of the defrost system (the air supply channel is frozen) or a breakdown of the damper that regulates the flow of cold air. Freon leakage is also possible when its quantity is only enough for a small volume of the freezer.
How long should a new Indesit refrigerator cool down after delivery?
If the refrigerator was transported lying down, it needs to stand upright for at least 4-6 hours (preferably a day) before turning it on, so that the oil flows into the compressor. After the first turn on, the normal temperature will be established in 2-4 hours, a full load of food is possible after 12-24 hours.
Is it possible to use an Indesit refrigerator if it has stopped freezing, but is working?
You cannot use such a unit for storing food, as bacteria will begin to multiply in it. In addition, running “idle” without load and in violation of the temperature regime can finally finish off the compressor, turning a simple repair into an expensive motor replacement.
What does the flashing alarm indicator on the Indesit refrigerator mean?
A flashing indicator (often red) signals that the temperature in the chamber has risen above the permissible norm. This could be caused by loading warm food, the door not closing tightly, or an actual problem with the cooling system. If, after eliminating these factors, the indicator does not go off, diagnostics are required.
How often do you need to defrost a No Frost refrigerator?
Technically, the No Frost system does not require defrosting to remove ice, since this happens automatically. However, manufacturers recommend at least once a year (preferably in spring and autumn) to turn off the refrigerator, wash it and let it rest for 1-2 days to restore system resources and check the seals.
