The situation when food in the refrigerator compartment spoils or, conversely, everything turns into ice, and the freezer ceases to perform its function, causes panic for any home cook. Refrigerators Indesit have earned a reputation as reliable equipment, but even they have malfunctions, especially after several years of active use. The first thing you need to understand is the scale of the problem: the cold has disappeared completely or the temperature has simply become not low enough to freeze.
Before calling a technician or looking for spare parts, it is worth conducting an initial diagnosis yourself. Often the reason lies in trivial things, such as a door that is not tightly closed or the thermostat settings are off. However, if you hear that the compressor is humming, but there is no cold, or, conversely, there is complete silence, this is a signal of a more serious breakdown. In this article, we will look at the main reasons why the freezer in the Indesit refrigerator does not work, and we will help you determine whether you can fix the problem yourself.
It is important to note that modern models Indesit with a system No Frost are more complex than older units with a drip system. In them, fans are responsible for air circulation, and special defrost heaters are responsible for the absence of ice. Understanding the operating principle of your model will help you quickly find the culprit of the malfunction and avoid unnecessary expenses on repairs.
Primary diagnostics: settings and external factors
Often, equipment owners begin to sound the alarm ahead of time, without checking basic things. If the freezer is not freezing, first make sure that the appliance is properly connected to the network. Check to see if the power light is on and if there is a problem with the outlet. Sometimes a failure can occur due to a power surge, and the equipment needs time to reboot.
The second critical point is the position of the temperature regulator. In refrigerators Indesit the mechanical thermostat may be accidentally moved to the "minimum" or "0" position during cleaning or loading food. Electronic controls can also go wrong. Make sure that the set mode meets the requirements for freezing.
⚠️ Attention: If you have just defrosted the refrigerator or transported it lying down, do not turn it on for at least 4-6 hours. The oil in the compressor needs time to drain into the crankcase, otherwise starting can lead to water hammer and final breakdown of the unit.
It is also worth paying attention to the tightness of the door. If the rubber seal is worn out, dirty or deformed, cold air constantly escapes out. The compressor will work non-stop, trying to compensate for heat loss, but will not reach the desired temperature in the freezer. Check the seal around the entire perimeter.
Malfunctions of the defrost system in No Frost models
Refrigerators Indesit with the system No Frost are susceptible to one specific problem - fouling of the evaporator with ice. Normally, the system automatically defrosts the evaporator several times a day. If this process is disrupted, the ice coat blocks the cold air supply channels, and it stops flowing into the freezer and refrigerator compartments.
The main culprits in this situation are the defrost heating element, defrost sensor or timer (control module). The heating element may simply burn out over time, like a regular light bulb. The sensor that controls the temperature of the evaporator may “lie”, not giving a command to turn on the heater. As a result, the fan circulates air, but the evaporator is clogged with ice.
Diagnostics often require partial disassembly of the rear wall of the freezer. You can visually estimate the amount of ice. If you see a massive piece of ice on the evaporator, the defrost system is not working. You can ring the heating element and sensor with a multimeter, but this requires skills in working with electrical appliances.
Symptoms of faulty defrosting
If you hear that the fan inside the freezer is humming or crackling, but the cold is not coming out, most likely its blades are touching ice. This is a sure sign that the defrosting system is not coping well, and the evaporator is overgrown with ice.
Problems with the compressor and start relay
The compressor is the heart of the refrigerator Indesit. If it doesn't start, there won't be any cold anywhere. You can often hear a characteristic click, a hum for a few seconds, and then another click and silence. This is a classic symptom of a faulty start relay or the compressor itself.
The start relay is a small plastic block that fits over the contacts of the compressor. Inside it is a mechanism that starts the motor. Over time, the contacts burn out or the mechanism jams. Replacing a relay is one of the simplest and cheapest repair procedures, which you can do yourself by selecting an analogue according to the model.
A more serious situation is a malfunction of the compressor itself. If the motor windings burn out or an interturn short circuit occurs, the unit will either not start at all or will knock out the circuit breaker in the apartment. In this case, a professional replacement of the compressor with recharging the system with refrigerant is required.
☑️ Compressor diagnostics
Freon leak: how to detect and what to do
If the compressor works almost non-stop, hums, but the temperature in the freezer is higher than normal or equal to room temperature, there is a high probability of leakage refrigerant (freon). In refrigerators Indesit this is a common problem, especially in models where the foamed evaporator is located in the walls of the case.
It is difficult to determine the leak visually, since freon is colorless and odorless. Indirect signs are:
- 🔹 Hot side walls of the refrigerator (normally they should be warm, but not hot).
- 🔹 Absence of characteristic gurgling or hissing when the compressor operates and stops.
- 🔹 The appearance of swelling on the internal or external the chamber wall in the place of the foamed evaporator.
- 🔹 Oil around the compressor or at the pipe connections (if the leak is in an open area).
It is impossible to eliminate the leak and fill the refrigerator with freon on your own. Special equipment is required: a vacuum pump, a pressure gauge station and scales. In addition, it is necessary to find the leak, seal it and replace the filter drier. Attempts to simply “add gas” will lead to repeated breakdown in a short time.
⚠️ Attention: Do not try to look for a leak using an open flame (lighter) near a running refrigerator. Although modern freons are not flammable, upon contact with an open flame they can emit toxic substances that are hazardous to health.
Malfunctions of the thermostat and control module
The thermostat (thermostat) or electronic control module is responsible for maintaining the set temperature. If the thermostat is stuck in the off position, the compressor simply will not receive a signal to start. In mechanical models Indesit this is solved by replacing the thermostat, which is a relatively inexpensive procedure.
In models with electronic control (Indesit NBA, EF and other series), the board is responsible for all processes. A power surge in the network can damage the compressor control triac or other board elements. In this case, the refrigerator may behave inappropriately: freeze too much or not turn on at all.
Diagnostics of electronics requires knowledge of circuit design. If you see error codes on the display (for example, flashing temperature indicators), the explanation of which is in the instructions, this will indicate a specific unit. However, often the board burns out silently, without external signs, except for the lack of response to commands.
Table of main faults and symptoms
For convenience, we systematize the main problems faced by refrigerator owners Indesitinto a single table. This will help you quickly navigate the nature of the breakdown.
| Symptom | Probable cause | Difficulty of repair | Need a technician |
|---|---|---|---|
| Compressor does not start, silence | Faulty start relay or thermostat | Low | No (you can do it yourself) |
| Buzzes, clicks, but does not start | The compressor is jammed or the relay is burned out | High | Yes (compressor replacement) |
| Works without stopping, little cold | Freon leak or capillary blockage | High | Yes (refilling needed) |
| There is a coat of ice in the freezer, there is no cold | The defrosting system (heating element, sensor) is faulty | Average | Desirable |
| The refrigerator is very cold | Thermostat or module is faulty | Average | Preferable |
As can be seen from the table, many problems require professional intervention, especially those related to the sealed circuit and refrigerant. However, simple elements, such as relays and thermostats in mechanical models, are often changed by users on their own.
When to call a specialist, and when you can do it yourself
The decision to repair it yourself should be based on your skills and the availability of tools. If we are talking about replacing a light bulb, door seal or start relay (if you have access and skills to work with electricians), you can try to do it yourself. The user can also completely defrost the refrigerator within 24 hours, which sometimes helps to defrost the ice plug in the capillary (although this is a temporary measure).
However, if the diagnostics indicate a freon leak, a clogged capillary tube or a compressor malfunction, calling a technician is inevitable. These works require evacuation of the system, precise dosage of refrigerant and the use of special tools. Unprofessional repairs in this case will lead to permanent failure of the equipment.
It is also worth contacting the service if the refrigerator is under warranty. Opening the seals or independently tampering with the structure will void the manufacturer's warranty Indesit. Remember that saving on diagnostics can lead to more expensive repairs in the future.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator hum but not freeze?
Most likely, the capillary tube is clogged or there is a freon leak. The compressor tries to pump the refrigerant, but cannot due to an obstruction or lack of it in the system. Diagnostics by a technician is required.
How long should it take to defrost a No Frost refrigerator?
To completely melt the ice in hard-to-reach places and evaporate moisture, it is recommended to defrost the refrigerator Indesit with the No Frost system for at least 24 hours, even if visually there is no more ice.
Is it possible to replace the compressor on an Indesit refrigerator yourself?
Theoretically, it is possible if you have the skills to solder copper pipes and equipment for vacuuming. However, without experience, there is a high risk of poor-quality soldering, moisture entering the system and repeated breakdown. It is recommended to entrust this to professionals.
What does a flashing temperature indicator in the freezer mean?
A flashing indicator usually signals that the temperature in the freezer has risen above the permissible limit. This may be a consequence of loading warm products, a door that is not tightly closed, or a technical malfunction.
How often do you need to defrost the Indesit refrigerator?
Models with the system No Frost do not need regular defrosting, it is enough to wash them 1-2 times a year. Models with a drip system (crying evaporator) require defrosting as ice forms, usually 1-2 times a year.
