Why the Indesit refrigerator does not freeze, but the freezer works: reasons

The situation when Indesit refrigerator stops cooling the main compartment, while the freezer continues to properly freeze food, is one of the most common complaints from owners of this equipment. This behavior of the unit often confuses the user: the motor seems to be humming, the lights are on, but the temperature in the refrigerator compartment is rapidly rising, and the food begins to spoil. This indicates that the cooling system is working, but the cold circulation is disrupted in the upper or middle part of the device.

The reasons for such dysfunction can vary from simple blockage of ventilation ducts to serious mechanical damage compressor or refrigerant leakage. Unlike a refrigerator completely stopping, a partial malfunction often gives the false impression that it will “fix itself” or “just need to wait.” However, in the case of equipment Indesit, especially models with a No Frost system or a crying evaporator, ignoring the problem in the first 24 hours can lead to complete damage to the supply of products.

In this article we will analyze in detail why the refrigerator does not workif The freezer is functioning normally. We will look at the self-diagnosis algorithm, typical faults for different models, and situations when calling a technician becomes inevitable. Understanding the principles of operation the refrigeration circuit will help you make the right decision about repairs.

Fundamental differences in cooling systems in Indesit refrigerators

To understand the essence of the problem, you need to briefly refresh your memory about the design of a refrigeration cabinet. Most modern models Indesit use one compressor that circulates freon in a single circle, but cooling of different chambers occurs in different ways. In classic two-chamber models, freon first passes through the evaporator of the freezer, where it boils at very low temperatures, and then, already heated, enters the evaporator of the refrigerator compartment.

If the freezer is working, this means that it starts up, creates pressure, and there is freon in the system. The problem lies in the fact that the cold either does not reach the main chamber or is not retained there. In models with the system compressor starts, creates pressure, and there is freon in the system. The problem lies in the fact that the cold either does not reach the main chamber or is not retained there. In models with the system No Frost the fan is responsible for the distribution of cold. If it has stopped or the damper has blocked the channel, it will become warm in the refrigerator compartment, despite the motor running.

It is important to distinguish between models with a drip defrosting system and a defrosting system No Frost. In the first, the cold is transmitted through the back wall, which periodically thaws. Secondly, cold air is pumped by a fan. Malfunctioning airflow controls are a common reason why your freezer won't work. An error in diagnosing the type of system can lead to incorrect repairs. The refrigerator does not freeze, and the freezer is working. An error in diagnosing the type of system can lead to incorrect repairs.

⚠️ Attention: If you hear that the compressor is running continuously without turning off, and the temperature in the refrigerator compartment is above +10°C, this is a sure sign of a freon leak or a clogged capillary tube. Operation in this mode will quickly damage the motor.

It is also worth considering the age of the equipment. Older models Indesit often used compressors that were sensitive to voltage fluctuations, which could lead to loss of performance. Modern inverter models have complex electronics that can block the supply of cold to one of the chambers if the sensors fail.

Natural causes and simple diagnostics

Before panicking and looking for a service center number, it is worth excluding trivial causes that do not require intervention refrigeration circuit. Often users forget about simple things that affect air circulation. Checking these points will take no more than 10 minutes, but can save time and money.

The first thing you need to pay attention to is the tightness of the doors and the condition of the seals. If the rubber on the refrigerator door is torn, dirty, or simply does not fit tightly due to the door being skewed, the cold will evaporate faster than it can be produced. As a result, the freezer, which has more powerful insulation and a low temperature, will continue to work, and the main chamber will become warm.

The second important factor is the location of the products. In models No Frost ventilation holes are often located on the back wall or on the top. If you place a pan or bag directly in front of them, air circulation is blocked. Cold air remains in the freezer or at the back wall, without spreading throughout the volume.

• 🔍 Check to see if ice has frozen on the back wall of the refrigerator compartment (in drip models), which could block the flow of melt water.
• ❄️ Make sure the thermostat is not set to the minimum value by accident.
• 🚪 Inspect the door hinges to see if the refrigerator door is sagging.
• 🌡️ Measure the temperature at different points in the chamber to understand the location of the problem.

⚠️ Attention: Never try to pick out the ice with a knife or sharp objects. Damage to the evaporator hidden behind the plastic panel will lead to an immediate release of freon and expensive repairs with soldering.

Another “natural” reason may be recent defrosting. If you just cleaned the refrigerator and turned it on, but didn't let it sit empty for at least 2-3 hours, it may not get up to temperature. This is especially true if warm products were immediately loaded into the chamber. Thermostat may not feel a real increase in temperature due to inertia.

Problems with the defrost system (No Frost)

If your Indesit equipped system No Frost, then the most likely reason that the refrigerator does not freeze, but the freezer is working, is a malfunction of the defrost system. The essence of the problem is this: the evaporator, located behind the rear panel of the freezer, becomes covered with ice. The fan, which should drive cold air into the upper chamber, either stops due to the ice crust, or the air simply cannot pass through the channel clogged with ice.

In this case, the freezer continues to freeze, since the evaporator is inside it and it has enough cold. However, no air enters the refrigerator compartment. This is often accompanied by silence - you do not hear the noise of the fan, which usually hums slightly when operating. Or you can hear the characteristic crack of breaking ice.

The key elements that fail in this chain are:

• 🔥 Defrost heating element - a heating element that melts the ice on the evaporator.
• ⏱️ Defrost timer or electronic module - controls the switching cycles Heating element.
• 🌡️ Defrost sensor (defrost) - monitors the temperature of the evaporator.
• 💨 Fan - carries out forced air circulation.

Diagnostics requires partial disassembly of the freezer. It is necessary to remove the back plastic panel and visually assess the amount of ice on the evaporator. If there is a “snowdrift” there, and the refrigerator hums, but does not cool in the upper compartment, the problem is confirmed. Replacing the heating element or sensor is a standard procedure for service centers.

Is it possible to defrost the refrigerator manually to check the hypothesis?

Yes, this is the best diagnostic method. Unplug the refrigerator for 10-12 hours (minimum) with the doors open. If, after turning on and completely defrosting, it begins to freeze normally in both chambers, but after 1-2 weeks the problem returns, it means that the defrosting system (heating element, timer or sensor) is faulty and requires replacement.

It is worth noting that in some models Indesit with two fans (one for the freezer, one for the refrigerator), it is the motor responsible for upper chamber. In this case, there may be no ice on the evaporator, but air simply will not be pumped.

Freon leak and capillary tube clogged

More serious technical problems, such as a refrigerant leak or clog, also show symptoms when the freezer works but the refrigerator does not. When freon leaks, its amount in the system gradually decreases. Since the freezer's evaporator is at the beginning of the circuit, it gets all the remaining gas, and it continues to freeze (sometimes even more than usual, since the compressor works non-stop). Freon simply does not reach the refrigerator compartment in the required volume or condition.

Clogged capillary tube is when moisture, oil or breakdown products enter the narrow channel through which freon circulates. An ice or mud plug forms. The pressure in the system increases, the compressor hums, but the circulation is disrupted. Often in such cases, you can hear gurgling or see that the filter drier (the metal cylinder near the compressor) is covered with frost or, conversely, heated.

The main signs of these problems:

• 🔊 The compressor works continuously without turning off.
• 🌡️ The condenser grille at the back of the refrigerator is either cold or only partially hot.
• 💧 The appearance of oily spots near the compressor (in case of a leak).
• 🧊 Blistering of the rear wall inside the refrigerator (when water freezes in the insulation).

Repair in case of a leak or blockage requires qualified intervention. The technician must find the leak (often a foamed evaporator or pipe joints), solder it, evacuate the system and fill it with new freon. It is impossible to perform this operation on your own without equipment.

Malfunction of the compressor and starting relay

Although the compressor seems to be working properly when the freezer is running, this is not always the case. Dual circuit or variable displacement compressors may have defective valves. If the valves are worn out, the compressor may not create enough pressure to pump freon through the entire circuit, but there is enough pressure to service a small freezer.

It is also worth checking the start relay. If it burns out or is unstable, the compressor may have difficulty starting, humming, but not developing full power. In some cases, the relay turns off the motor as soon as it tries to enter the operating mode, but during this short time the freezer manages to freeze, creating the illusion of operation.

Compressor diagnostics include:

1. Measuring the current strength of the windings.
2. Checking the outlet pressure compressor.
3. Analysis of operating noise (metallic clanging or humming).

Replacing a compressor is a complex and expensive process that requires resoldering the tubes and refilling with freon. It is often more economically feasible to purchase a new refrigerator if the old one is more than 10 years old.

Comparison of symptoms: Table of faults

For ease of diagnosis, we have collected the main symptoms in a table. This will help you quickly navigate the nature of your breakdown Indesit.

As can be seen from the table, the external manifestations may be similar, but the reasons are radically different. For example, continuous running of the motor can indicate either a simple leak or a serious blockage. Only a master with a manometric manifold can make an accurate diagnosis.

When you need to call a specialist

There is a fine line between do-it-yourself repairs and the need for professional intervention. If the problem is solved by defrosting or replacing the light bulb, that’s one thing. But when it comes to refrigeration circuitthe risks are too great. Incorrect soldering can lead to a fire, and poor-quality vacuuming can lead to compressor failure in a month.

Calling a technician is required in the following cases:

• 🛠️ You suspect a freon leak (special tools are needed for search and refueling).
• 🔌 The compressor requires replacement (tubes need to be resoldered and refilled).
• ❄️ The No Frost system requires complex disassembly, which you cannot get to without the risk of damaging the plastic.
• ⚡ There are problems with the electronic control module (need flashing or soldering the board).

⚠️ Attention: Prices for repairing Indesit refrigerators may vary depending on the region and model. The cost of spare parts (especially compressors) also varies. Before starting work, always check the total amount with the technician, including visit and diagnostics.

Remember that calling a specialist in a timely manner at the first sign of a freon leak will save the compressor from overheating. If the refrigerator runs “idle” for days, the motor burns out, and then repairs become economically unfeasible.

Frequently asked questions (FAQ)

Why does the Indesit refrigerator freeze only near the back wall?

This is a characteristic sign for a drip system if everything works fine. However, if the cold does not spread, the air ducts (in No Frost) may be clogged or the damper that regulates the flow of cold air is faulty. This could also be the initial stage of a freon leak.

Is it possible to operate the refrigerator if the upper chamber does not freeze?

For a short time - yes, so that the food in the freezer does not disappear. But you can’t work like this for long. The compressor will work hard, trying to gain temperature, which will lead to overheating and combustion. In addition, the food in the upper chamber will quickly deteriorate.

How long does it take to defrost the refrigerator to check?

To completely defrost the No Frost system and the evaporator, you need at least 10-12 hours, preferably a day. During this time, all the ice in the hidden cavities will have time to melt. Turning on after 2-3 hours may not give a result, since an ice plug could remain in the channel.

Where is the temperature sensor in the Indesit refrigerator?

Depending on the model, the sensor (thermostat) may be located inside the refrigerator compartment (plastic handle with numbers), on the back wall inside or behind the rear panel of the freezer compartment (sensor defrost). In electronic models, the sensors are often hidden in plastic cases.

Why did the refrigerator work after defrosting, but then stopped again a week later?

This is a classic symptom of a malfunctioning defrost system. Defrosting removed the ice and air began to flow. But since the heating element, timer or sensor did not work, ice accumulated again within a week and blocked the channel again. A faulty element of the defrost system needs to be replaced.
