The Indesit refrigerator does not cool: causes of the malfunction and what to do

The refrigerator Indesit stops cooling, and the food in the chambers quickly deteriorates? Do not rush to call a specialist - in 60% of cases the problem can be fixed on your own. This article will help you understand why the unit does not freeze, even if the compressor is running and the light inside is on. We analyzed typical breakdowns of models Indesit C 138 NF, Indesit DF 4180 W and other popular series, and also collected proven diagnostic methods.

Cooling problems can be associated with both mechanical failures (compressor wear, freon leakage) and operating errors (improper installation, overloading of chambers). It is important to understand what exactly went wrong: thermostat, No Frost fan, start relay or electronic module. In some cases, it is enough to defrost the refrigerator or clean the condenser, in others, you will need to replace parts.

1. Primary diagnostics: what to check first

Before disassembling the refrigerator, exclude obvious causes not related to breakdowns. Start by inspecting network cable the socket - perhaps the voltage in the network is insufficient (normal: 220–240 V). Check:

• 🔌 Power: connect another device to the same outlet to make sure it works. If the refrigerator Indesit suddenly turns off, check the machine in the panel.
• 🔄 Mode: some models (for example, Indesit BIAA 13) have a "Vacation" function (Holiday), in which the refrigerator compartment is turned off, and The freezer operates in the minimum mode.
• 🌡️ Temperature: If an error flashes on the display (for example, F02 or F04), this may indicate a sensor malfunction.

Pay attention to compressor noise. If it:

• ❌ Does not turn on at all - there is a problem in the start relay, thermostat or electrical circuit.
• ⚠️ Works without stopping - there may be a freon leak, a clogged capillary tube or a breakdown of the thermostat.
• ✅ It turns on, but turns off after 5-10 seconds —the start-protection relay is faulty.

If the refrigerator Indesit with the system No Frost stops cooling, listen to the fan working. The absence of a hum may indicate icing of the blades or failure of the motor. In models with a drip system (Indesit TS 11), check if the drainage hole is clogged - this leads to ice accumulation on the back wall and poor cooling.

2. The compressor works, but the refrigerator does not cool: top 3 reasons

The situation when the motor hums, but the temperature in the chambers does not drop, typical for refrigerators Indesit over 5 years old. The culprits most often are:

🔧 Freon leak

Freon (refrigerant R-134a or R-600a) circulates in a closed circuit, removing heat from the chambers. If the seal is broken (for example, due to corrosion of the tubes or mechanical damage), the gas escapes and cooling stops. Signs:

• 🧊 The compressor works without stopping, but does not freeze.
• 🔥 The condenser (grid on the back wall) remains cold.
• 🛠️ Oil stains are visible on the tubes or in solder areas.

A leak can only be detected using leak detector or a soap solution (at home). It is impossible to refill freon yourself - a vacuum pump and special equipment are required. Average repair cost: from 3,500 to 6,000 rubles (depending on the model).

❄️ Capillary tube clogged

Capillary is a thin copper tube through which freon enters the evaporator. Over time, it can become clogged with oil decomposition products or moisture. Symptoms:

• ⏳ The refrigerator cools, but very slowly (the temperature drops in 6-8 hours instead of 1-2).
• 🔊 The compressor is overloaded, overheating is possible.
• 🧊 The freezer is covered with thick a layer of ice.

To clean the capillary, the master uses hydraulic flushing or nitrogen purging. If the blockage is severe, the tube may be replaced. Service price: from 2,500 rubles.

🌡️ Malfunction of the thermostat (thermostat)

The thermostat is responsible for turning the compressor on/off depending on the temperature. In models Indesit it often fails due to oxidation of contacts or mechanical wear. How to check:

1. Disconnect the refrigerator from the network.
2. Remove the protective casing from the thermostat (usually located inside the chamber, next to the lamp).
3. Short the 2 wires going to the thermostat (usually brown and red).
4. Turn on the refrigerator. If the compressor works, the thermostat is faulty.

The cost of a new thermostat for Indesit: from 800 to 2,000 rubles. Replacement takes 20–30 minutes.

3. Indesit refrigerator does not turn on: electrical problems

If the unit does not show signs of life (lights do not light up, compressor noise is not heard), the problem lies in the electrical circuit. Let's consider typical malfunctions:

Pay special attention start relay this is the weak point of refrigerators Indesit with inverter compressors. If the relay breaks, the compressor cannot start, although voltage is supplied to it. To check the relay:

1. Disconnect the refrigerator from the mains.
2. Remove the relay (usually attached to the side of the compressor).
3. Shake it - if you hear knocking or rattling, this is a sign of a malfunction.
4. Ring the coil contacts with a multimeter (resistance should be 20-40 Ohms).

⚠️ Attention: If the refrigerator compressor Indesit overheats (the body is hot, but the motor does not start), under no circumstances try to turn it on again. This can lead to inter-turn short circuit of the windings and complete breakdown of the motor. Let it cool for 1-2 hours.

4. Problems with the No Frost system: why the freezer compartment does not cool

Refrigerators Indesit with the system No Frost (models Indesit ITF 118, Indesit EF 18) often suffer from fan malfunctions or icing of the evaporator. If the freezer is not freezing, but the refrigerator is working normally, check:

• 🌀 Fan: it should rotate when the door is open (in some models - only when the door is closed). If the blades are covered with ice, defrost the refrigerator for 12–24 hours.
• 🔥 Defrost heating element: If the heater breaks down, the evaporator becomes covered with ice and the cold stops flowing into the chambers. Test the heating element with a multimeter (resistance should be 200–500 Ohms).
• 🌡️ Defrost sensor: if it is faulty, the control board does not turn on the heating element, and the ice does not melt. Replacing the sensor will cost 1,000–1,500 rubles.

To defrost the system No Frost correctly:

Disconnect the refrigerator from the mains|Remove all food and shelves|Leave doors open for 12–24 hours|Wipe the internal surfaces with a dry cloth|Do not use a hair dryer or other heating devices-->

If the problem persists after defrosting, it is most likely faulty defrost timer or fuse. In models Indesit with electronic control (Indesit BIAA 13 F), the malfunction may be due to a board firmware failure. In this case, only flashing or replacing the module will help.

⚠️ Attention: In refrigerators Indesit with a system No Frost it is strictly forbidden to chip ice with a knife or other sharp objects. This can damage the evaporator and lead to a freon leak. Use only plastic spatulas.

5. The refrigerator compartment does not cool, but the freezer is working: what to do

If the freezer is freezing, but the temperature in the refrigerator compartment is above +10°C, the problem may be:

• 🔌 Drainage clogged holes (water does not drain, ice forms on the back wall).
• 🌀 Fan failure (in models with No Frost cold does not enter the refrigerator compartment).
• 🌡️ Faults dampers (in two-compressor models it regulates the flow of cold air).
• 🔧 Freon leak in the refrigeration chamber circuit (occurs rarely, usually after mechanical damage).

For models Indesit with one compressor (for example, Indesit C 132 G) A typical problem is with with the damper, which freezes in the closed position. To defrost it:

1. Disconnect the refrigerator from the mains.
2. Remove all products from the refrigerator compartment.
3. Put a heating pad with warm water (not boiling water!) into the chamber or point the fan at the back wall.
4. After 1–2 hours, try opening the damper manually (it is located behind the plastic panel on the back wall).

If the damper is mechanically broken, it will have to be replaced (part cost: 1,200–2,500 rubles). In refrigerators with electronic control the problem may lie in a malfunction of the refrigeration chamber temperature sensor. It is checked with a multimeter (the resistance should change when heating/cooling).

How to check the temperature sensor in an Indesit refrigerator

1. Unplug the refrigerator.

2. Remove the protective cover from the sensor (usually located on the back wall of the camera).

3. Disconnect the connector and test the sensor with a multimeter in resistance measurement mode.

4. Normal values: at +20°C - 5–7 kOhm, at 0°C — 12–15 kOhm. If the resistance does not change or is equal to 0/∞, the sensor is faulty.

6. Typical user mistakes that cause the refrigerator to stop cooling

In 30% of cases, cooling problems are caused by improper operation. Here are the most common mistakes:

• 🚪 Frequent or prolonged opening of doors. Every time you open the refrigerator, the temperature inside rises by 2-4°C. If the unit does not have time to restore the cold, the compressor works without stopping and may overheat.
• 🍲 Hot food. Placing hot dishes or pots in the chamber leads to the formation of condensation and icing of the evaporator. In models Indesit s No Frost this may damage the fan.
• 🧊 Overload of the freezer compartment. If food is packed too tightly, air circulation is disrupted and the temperature is distributed unevenly. This may cause the refrigerator compartment to become warmer.
• 🔌 Unstable voltage. Refrigerators Indesit are sensitive to voltage surges. If the network is often less than 200 V or more than 250 V, this may damage the electronic module or compressor.

To extend the life of the refrigerator, follow simple rules:

• 📏 The distance from the back wall to the wall must be at least 5 cm (for ventilation compressor).
• ☀️ Do not place the refrigerator next to the stove, radiator or in the sun.
• 🧹 Once every 6 months, clean the condenser (grid on the back wall) from dust.
• ❄️ Defrost the refrigerator with a drip system once every 6–12 months, from No Frost - once every 1–2 years.

⚠️ Attention: If your refrigerator Indesit was manufactured before 2015, it may use refrigerant R-12 or R-22which today prohibited. If freon leaks, the technician is obliged to replace it with a modern analogue (R-134a or R-600a), but this may require modification of the system. Check the details at the service center.

7. Repair cost vs. buying a new refrigerator: which is more profitable?

If yours Indesit has served for more than 10 years, before repairing, evaluate how feasible it is. Below is a comparative table of costs for replacing key components:

Average cost of a new refrigerator Indesit volume 200–250 l: 25,000–35,000 rubles. If repairs will cost 40–50% of this amount, it makes sense to consider purchasing new equipment, especially if:

• 🕒 The refrigerator is more than 12 years old.
• 🔧 There has already been a major overhaul (replacement of the compressor, evaporator).
• 📉 Energy consumption has increased by 30–40% (compare with the data on the sticker).
• 🔊 The noise level exceeds 45 dB (modern models are quieter).

When choosing a new refrigerator, pay attention to models with inverter compressor (for example, Indesit EIAA 12) - they consume 20-30% less electricity and last longer than traditional ones.

8. Step-by-step instructions: what to do if the Indesit refrigerator does not cool

Follow this algorithm to quickly determine the cause of the malfunction:

1. Check the power supply:
   • Make sure the plug is firmly inserted into the socket.
   • Check mains voltage (should be 220–240 V).
   • If the refrigerator turns off after a power surge, wait 15 minutes and turn it on again.
2. Inspect the compressor:
   • If it does not start, check the start relay (knock on it - sometimes helps).
   • If the compressor is hot, let it cool for 1-2 hours.
3. Check the temperature in the chambers:
   • If the freezer is working but the refrigerator is not, look for a problem in the damper or fan.
   • If not both chambers are freezing, the compressor, thermostat or freon leak is to blame.
4. Defrost the refrigerator:
   • Turn off the power for 12-24 hours.
   • Wipe all surfaces dry.
   • After switching on, allow 2-3 hours for the temperature to restore.

Contact service if:

• The compressor is working, but does not cool.
• An error is displayed on the display (F02, F04, F07).
• A loud noise is heard or vibration.

If you decide to repair the refrigerator yourself, follow the safety rules:

• ⚡ Unplug the refrigerator before any work.
• 🔧 Do not disassemble the compressor or freon circuit without special skills.
• 📞 For replacing freon or soldering pipes, invite a specialist.

How to find a good repairman for Indesit refrigerators

1. Look for services with an official license to work with refrigerants.

2. Check reviews on Yandex.Maps or 2GIS (pay attention to photo "before/after").

3. Check if they provide a warranty for repairs (minimum 6 months).

4. Ask if they use original spare parts or analogues (parts from Ariston and Hotpoint are suitable for Indesit).

5. Compare prices: too low a price may mean using used ones. components.

❓ Why does the Indesit refrigerator not cool, but the light inside is on?

If the light works and the compressor does not start, the problem may be in:

• start relay (does not give a signal to start the motor);
• thermostat (does not close the contacts to turn on the compressor);
• electronic module (does not send a cooling command).

First check the relay - it most often fails. If after replacing the relay the compressor does not work, diagnose the thermostat or board.

❓ How to understand what is in the Indesit refrigerator. freon leak?

Signs of a leak:

• the compressor works without stopping, but does not freeze;
• the condenser (grid at the back) remains cold;
• oil oil is visible on the tubes or in the soldering areas stains;
• little ice forms in the freezer or it melts.

It is impossible to eliminate the leak on your own - special equipment is required for vacuuming and charging freon.

❓ Is it possible to turn on the Indesit refrigerator after transporting it lying down?

If the refrigerator was transported in a horizontal position, before turning it on you need to:

1. Let it stand vertically for 4-6 hours (so that the oil from the compressor drains back).
2. Check whether the refrigerant tubes are damaged.
3. Connect to the network and observe 1–2 hours: if the compressor starts and cooling is ongoing, everything is in order.

If after transportation the refrigerator does not turn on or works intermittently, call a technician - there may be a freon leak or damage to the compressor.

❓ How much does it cost to fill freon into an Indesit refrigerator?

The cost depends on:

• type of refrigerant (R-134a cheaper, R-600a more expensive);
• system volume (larger refrigerators require more freon);
• the need to solder the tubes (if there was a leak).

Average prices in Moscow in 2026:

• Diagnostics of a leak: 1,000–1,500 rubles.
• Refilling freon without repairing the tubes: 2,500–3,500 rub.
• Refilling + soldering 1–2 leak points: 4,000–6,000 rub.

❓ Why does the Indesit refrigerator with No Frost freeze ice in the freezer?

In systems No Frost ice in the freezer is formed due to:

• breakage defrost heating element (frost on the evaporator does not melt);
• malfunction defrost sensor (does not give a command to turn on the heating element);
• clogging drainage hole (water does not drain, freezes at the bottom);
• breakdown defrost timer (in mechanical systems).

To eliminate it, defrost the refrigerator for 24 hours. If ice appears again, you need to replace the heating element or. sensor.
