Why the Indesit refrigerator compressor does not work: a complete analysis of the reasons and solutions

Have you opened the refrigerator Indesitand there is an unexpected warm temperature inside, the motor does not hum, or the compressor turns on for a few seconds and immediately turns off? Such symptoms clearly indicate a problem with the “heart” of the unit - the compressor. But don’t rush to call a technician: in 60% of cases, the malfunction can be fixed on your own, saving on diagnostics and repairs.

In this article we will look at why the refrigerator compressor all possible reasons, according to which the refrigerator compressor Indesit may not work - from a banal lack of power to serious damage to the windings. You will learn how to diagnose the problem without special tools, which parts to check first, and in which cases the help of a professional is really required. And for models Indesit with a system No Frost we have allocated a separate section - their compressors often suffer from specific malfunctions.

We warn you right away: if your refrigerator is on guarantee do not disassemble it yourself - this will void the warranty. But if the warranty has expired or you are ready to take a risk, our instructions will help you save up to 5,000 rubles on a technician’s visit.

1. The compressor does not turn on at all: where to start diagnostics

If the refrigerator compressor Indesit does not show signs of life - there is no hum, vibration, and it is warm inside the chamber, start by checking basic things. B 30% of cases the problem does not lie in the compressor itself, but in the power circuit or control electronics.

First of all, make sure that:

• 🔌 The refrigerator is connected to the outlet (check the plug and cable for damage).
• 💡 There is voltage in the outlet (connect another device, for example, a tabletop lamp).
• ⚡ The automatic switch on the panel did not work (check the plugs or RCD).
• ❄️ The temperature mode is not set to 0 or OFF (on some models Indesit this turns off the compressor).

If everything is in order with the power supply, proceed to check start relay - this is the weak point of refrigerators Indesit over 5 years old. The relay is attached directly to the compressor and often fails due to overheating or power surges. Signs of a relay malfunction:

• 🔊 The compressor tries to start (a click is heard), but immediately turns off.
• 🔥 The relay smells like burning or burnt contacts are visible.
• ⚡ Appliances in the house blink when you try to start the refrigerator (voltage surges).

To check the relay, unplug the refrigerator, remove the protective casing from the compressor and inspect the part. If there are cracks, melting or black spots on the relay body, it needs to be replaced. On models Indesit with inverter compressors (series NBA, SBA), the relay is integrated into the control board - you can’t do without a technician.

2. The compressor hums, but does not start: top 3 reasons

The situation when the refrigerator compressor Indesit hums but does not start pumping refrigerant is one of the most insidious. Both mechanical faults and electronics can be to blame here. Let's look at the three most common scenarios.

1. The compressor motor is jammed. This occurs due to bearing wear, metal shavings getting into the windings, or overheating. Signs:

• 🔊 The hum of the motor becomes louder, then stops abruptly (thermal protection is triggered).
• 🔥 The compressor housing gets very hot within 10-15 minutes of operation.
• 🛠️ When you try to turn the compressor shaft by hand (after shutdown!) resistance or grinding is felt.

2. The start-up protection relay is faulty. Even if the relay is apparently intact, its contacts could “stick” or oxidize. It's easy to check:

1. Disconnect the refrigerator from the network.
2. Remove the relay from the compressor (disconnect the terminals).
3. Shake the part - if you hear a knock or the spring rattles, the relay is faulty.

3. Winding break or interturn short circuit. This is a serious failure that requires replacing the compressor. You can diagnose it with a multimeter:

• 📊 Measure the resistance between the compressor contacts (norm: 20–40 Ohms for the working winding, 10–20 Ohms for the starting winding).
• 🚨 If the resistance is equal 0 (short short circuit) or ∞ (break), the compressor is faulty.

3. The compressor works, but does not freeze: the refrigerant or the system is to blame. If the refrigerator compressor starts, hums, but the temperature in the chambers does not drop, the problem lies in a malfunction. Let's look at each case.

If the refrigerator compressor Indesit starts, hums, but the temperature in the chambers does not drop, the problem lies in freon leakage, clogged capillary tube or malfunction thermostat. Let's look at each case.

Freon leak is the most common cause of a “warm” refrigerator. Refrigerant leaks through microcracks in the circuit, and the compressor runs idle. Signs:

• 🧊 The condenser (grid on the back wall) remains cold even after an hour of operation.
• 🔍 Oil stains are visible on the tubes or in soldering areas (freon comes out along with the oil).
• ❄️ The freezer compartment is thawing, but there is no frost on the back wall of the refrigerator compartment.

It is almost impossible to eliminate the leak yourself - it requires refill with freon soldering the circuit. But you can temporarily “reanimate” the refrigerator if the leak is small:

1. Disconnect the device for 12-24 hours (let the oil drain back into the compressor).
2. Turn on the refrigerator and listen: if the compressor starts and starts to freeze, there is a leak non-critical.
3. Call a technician immediately - freon is poisonous, and its leakage is hazardous to health.

Clogged capillary tube is the second most common problem. Moisture, oil or dirt gets into the tube, blocking the circulation of freon. Symptoms:

• 🔄 The compressor works non-stop, but freezes weakly.
• 🌡️ The temperature in the freezer and refrigerator compartment is equally high.
• 🔧 To the touch, the capillary tube (thin copper tube in front of the evaporator) is icy only at the beginning, and then warm.

You can only clear the blockage at home Blowing with nitrogen - this requires a special cylinder and experience. Without equipment, you risk damaging the tube.

What will happen if you ignore the blockage of the capillary tube?

If the blockage is not removed, the compressor will wear out, which will lead to its overheating and failure. On average, the service life of the motor is reduced by 30–50% during constant operation under load.

4. Problems with the compressor in Indesit No Frost refrigerators

Models Indesit with system No Frost (for example, series DF, TN) have additional components that can affect the operation of the compressor: evaporator fan, defrost timer and heater. If the compressor is unstable, check:

1. Evaporator fan. If it does not rotate, cold air does not enter the chambers and the compressor overheats. Signs:

• 🌀 There is no airflow in the freezer (fan noise is usually heard).
• 🔥 The compressor turns off after 5-10 minutes of operation (protection is triggered).
• ❄️ There is a thick layer on the back wall of the freezer ice (the fan is blocked by ice).

To check the fan:

1. Unplug the refrigerator and defrost it for 12 hours.
2. Remove the back panel of the freezer (usually secured with latches).
3. Try turning it fan blades by hand - if they do not rotate, replace the motor.

2. Defrost timer. In systems No Frost it controls the defrost cycle. If the timer is stuck, the compressor may not start or may operate with long pauses. It’s easy to check:

• 🕒 Find the timer (usually a round plastic disk with the inscription Defrost Timer).
• 🔧 Turn the slot clockwise with a screwdriver until it clicks - if the compressor starts, the timer is faulty.

3. Evaporator heater. If the heater breaks, the evaporator freezes, blocking the air ducts. In this case, the compressor works hard, trying to compensate for the lack of cold. Signs:

• ❄️ The freezer is completely covered with ice, even after defrosting.
• 🔥 The refrigerator body is very hot at the bottom. (the compressor is overloaded).
• 📉 The temperature in the refrigerator compartment rises to +10...+15°C.

5. Electronic faults: control board and sensors

In modern refrigerators Indesit (series EWT, C) the compressor is responsible for operation. data-i="178">. If it fails, the compressor can: electronic control board. If it fails, the compressor may:

• 🔄 Turn on for 1-2 seconds and immediately turn off.
• 📛 Errors appear on the display F01, F02, F04 (compressor fault codes).
• 🔌 Do not respond to temperature changes on the control panel.

The most vulnerable elements of the board:

• 🔥 Resistors and capacitors (swell or crack from overheating).
• 🔌 Power connectors (contacts oxidize or come off).
• 📱 Control chip (fails during power surges).

You can check the board visually:

1. Turn off the refrigerator and remove the top cover (usually attached to 2–4 screws).
2. Inspect the board for blackened tracks, swollen capacitors or traces of burning.
3. Check all connectors - they should fit tightly, without play.

If you find damage, the board can be:

• 🔧 Repair (solder capacitors or resistors).
• 🔄 Replace with a new one (original boards for Indesit cost from 3,000 to 8,000 rubles).
• 📞 Send for repairs (in service centers repair boards for 1,500–3,000 rubles).

Temperature sensors - another weak point. If the sensor breaks, the control board receives incorrect data and controls the compressor incorrectly. You can check the sensor with a multimeter:

• 🌡️ The resistance of a working sensor at +20°C should be ~5–7 kOhm.
• ❄️ If you lower the sensor into ice, the resistance should increase to 20–30 kOhm.

6. Mechanical failures: what breaks in the compressor

If all the electronic components are working, but the compressor refrigerator Indesit still does not work, the problem lies in its mechanical part. Let's consider the most common faults.

1. groups. Over time, the pistons and cylinders of the compressor wear out, which leads to a drop in freon pressure:

• 🔊 The compressor hums louder than usual, but freezes weakly.
• 🔥 The compressor housing overheats (temperature above +90°C).
• 📉 The suction pressure (on the pressure gauge) is below 0.1 MPa.

2. Breakage of the valves. The compressor valves are responsible for the direction of movement of freon. If they break, the refrigerant circulates chaotically and the refrigerator stops freezing. Signs:

• 🌀 The compressor operates jerkily, with pauses. 10–30 seconds.
• 🌡️ The temperature in the chambers either drops or rises sharply.
• 🔧 Vibration is visible on the compressor tubes (the valves “knock”).

3. Depressurization of the housingIf a crack appears in the compressor, it leaks through it. freon and oil. This is a fatal failure - the compressor must be replaced. Signs:

• 🛢️ There are puddles of oil (usually black or brown) under the refrigerator.
• 🔊 The compressor makes a hissing sound (it comes out). gas).
• 🚨 Cracks or rust are visible on the compressor housing.

Mechanical breakdowns of the compressor cannot be repaired. - it can only be replaced. The cost of a new compressor for Indesit:

It is better to entrust the replacement of the compressor to a specialist - required evacuating the system, filling with freon and soldering the tubes. Independent replacement is fraught moisture getting into the circuitwhich will lead to repeated breakdown in 1-2 months.

7. When to call a technician: 5 critical cases

Some breakdowns of the refrigerator compressor Indesit cannot be eliminated without special equipment and skills. Here are 5 situations when independent repair is dangerous or ineffective:

1. Freon leak. Without a vacuum pump and a refrigerant cylinder, it is impossible to charge the system. In addition, freon is toxic - you can only work with it in a ventilated, protected area. data-i="240">1. Freon leak

2. Clogged capillary tube. Cleaning requires purging with nitrogen at a pressure of 15–20 bar. Without experience, you risk damaging the tube or capacitor.

3. Malfunction of the control board. Repair of electronic boards requires a soldering station. oscilloscope and knowledge of circuit design. An error in soldering can damage other components.

4. Mechanical damage to the compressor. Replacing the compressor carries the risk of moisture entering the system, which will lead to repeated failure.

5. data-i="250">Cost for a technician to visit Moscow and the region:. Such compressors (installed in models Indesit NBA, SBA) are controlled by complex electronics.

Cost of visiting a specialist in Moscow and the region:

• 🔧 Diagnostics: 1,000–1,500 rubles.
• 🛠️ Repair (replacement of relay, sensor, fan): 1,500–3,000 rubles.
• 🔄 Replacement of the compressor with refilling freon: 5,000–10,000 rubles.
• 📱 Repair of the control board: 2,000–4,000 rubles.

8. Prevention: how to extend the life of the compressor

Service life of the refrigerator compressor Indesit — 10–15 years, but if used incorrectly, it may fail within 3–5 years. To avoid breakdowns, follow these rules:

1. data-i="263">🔌 Voltage stabilizer (optimal for cottages and old houses).. Compressors Indesit use:

• 🔌 Voltage stabilizer (optimal for cottages and old houses).
• ⚡ Surge filter (protects against impulse noise).

2. refrigerator. If the compressor runs without stopping, it overheats:

• ❄️ Temperature in the refrigerator compartment: +4…+5°C.
• ❄️ Temperature in the freezer: –18°C.
• 🕒 Compressor work/rest ratio: 2:1 (for example, Works for 20 minutes, rests for 10 minutes).

3. Defrost your refrigerator regularly. Even models with No Frost need defrosting 1-2 times a year. This prevents:

• ❄️ Icing of the evaporator (reduces the load on the compressor).
• 🔧 Corrosion of tubes (humidity accelerates metal wear).

4. Check the door seal. A worn seal allows warm air to enter, causing the compressor to wear out. Signs:

• 🔍 There is a light visible on the door from the inside (the seal does not fit).
• ❄️ There is a thick layer of ice on the back wall of the refrigerator.

5. Do not place the refrigerator next to heat sources. Optimal location:

• 🌡️ Room temperature: +16...+32°C.
• ☀️ Distance from the stove or radiator: at least 50 cm.
• 🔌 Gap between the back wall and the wall: 5–10 cm (for ventilation).

Following these rules will increase the compressor life by 30–50% and save you money on repairs.
