The Indesit refrigerator turns on and immediately turns off - what to do?

The symptom is familiar to many: the refrigerator Indesit buzzes, starts up, and after a couple of seconds turns off. Sometimes the cycle repeats endlessly, sometimes the equipment “freezes” for hours. The reasons for this behavior vary from a banal failure to a serious breakdown requiring the intervention of a technician. It is important not to ignore the problem: constant power surges and overloads can lead to complete failure of the compressor or electronics.

In this article we will analyze all possible reasons, why the refrigerator Indesit turns on and immediately turns off - from a faulty start-up relay to problems with the control board. You will learn how to diagnose a breakdown yourself, when you can get by with minor repairs, and when it’s time to call a specialist. Spoiler: in 60% of cases, only 3 parts are to blame - and two of them can be easily replaced without a soldering iron.

1. Start-up protection relay: the most common reason

If the refrigerator Indesit clicks when turned on and immediately turns off, First of all, check the start-up protection relay. This small box attached to the compressor is responsible for starting the motor and protecting it from overloads. If there is a malfunction, the relay either does not supply current to the windings, or opens the circuit due to a false operation of the protection.

How does the breakdown manifest itself:

• 🔊 Click when you try to start, after which the refrigerator turns off.
• ⚡ Short operating cycle (1-3 seconds) with repetition after 5-10 minutes.
• 🔥 Hot relay - if you touch the box with your hand, it may be hot (but not always!).

Diagnostics:

1. Disconnect the refrigerator from the mains.
2. Remove the relay from the compressor (usually secured with latches or one screw).
3. Shake the part - if you hear knocking or rattling, this is a sign of mechanical wear.
4. Test the contacts with a multimeter (in resistance mode). Between the terminals C (common) and NO (normally open) the resistance should be 0 Ohm off.

⚠️

Attention: Do not confuse the start-up relay with a thermostat! The latter is located inside the chamber and is responsible for the temperature, and not for starting the compressor. If you replace the relay with a new one and the problem remains, look for the reason further.

2. Compressor malfunction: when the motor is “tired”

If the refrigerator compressor Indesit hums, but does not startor turns on for a split second, the motor itself may be to blame. Most often this happens due to:

• 🔋 Interturn short circuit in the windings (the compressor heats up, but does not create pressure).
• 🛠️ Wear of the piston group (the motor runs, but does not pump freon).
• ⚡ Breakthrough to the housing (can knock out an RCD or a automatic circuit breaker).

How to check the compressor:

1. Turn off the refrigerator and wait, until it cools down (1-2 hours).
2. Remove the start-up relay and connect the compressor directly to the network via an extension cord with a button (press for 1-2 seconds). If the motor does not start or makes a loud knock, it is faulty.
3. Call windings with a multimeter:
   • Resistance between C (common) and S (starting) — 20-40 Ohm.
   • Resistance between C and R (working) — 10-20 Ohm.
   • Resistance between S and R —the sum of the two previous values.

⚠️

Attention: If the compressor is “jammed” (the shaft does not rotate), do not try to start it by force - this may lead to breakage of the windings or damage to the valves. In this case, you will need to replace the motor or complete repairs with refilling freon.

3. Problems with the control board: the electronics are “buggy”

In modern models Indesit (for example, BIAA 13, DF 4180) the electronic board is responsible for starting the compressor. If it fails, the refrigerator may:

• 🔄 Turn on and off cyclically without pauses.
• 📛 Do not respond to temperature settings.
• 💥 Spark or smoke (in severe cases).

Causes of board malfunction:

• ⚡ Voltage surges in the network.
• 💧 Moisture ingress (condensation or leakage).
• 🛠️ Defective radio components (found in budget models).

How to diagnose:

1. Inspect the board for blackened elements (resistors, transistors, capacitors).
2. Check fuse on the board (if any) - it may be blown.
3. Ring power tracks for a break (relay contacts often oxidize).

⚠️

Attention: If you do not understand electronics, do not try to solder the board yourself! Improper repairs may result in a short circuit or fire. In most cases, it is cheaper to replace the entire module.

4. Temperature sensors: when the refrigerator is “deceived”

If the refrigerator Indesit turns on and immediately turns off, but at the same time the compressor is working and the relay is intactthe problem may lie in the sensors. In two-chamber models there are usually two of them:

• 🌡️ Evaporator sensor (responsible for the temperature in the freezer).
• 🧊 Air sensor (controls the overall temperature in the chamber).

Symptoms of sensor malfunction:

• 📉 Refrigerator does not get cold, but the motor runs jerkily.
• ❄️ In the freezer ice is forming, and the main chamber is too warm.
• 🔄 The display shows incorrect temperature (for example, -18°C at room temperature).

How to check the sensors:

1. Find the sensors (usually located behind the back wall or in the freezer).
2. Disconnect the connector and measure the resistance multimeter:
   • At 0°C — ~5 kOhm.
   • At 25°C — ~1.5 kOhm.

If resistance 0 (open) or ∞ (short circuit) - the sensor is faulty.

Where to buy sensors for Indesit?

Original sensors can be ordered by article number (indicated on the part body) at Indesit service centers or on spare parts websites (for example, Spare parts for refrigerators, All-Spare). They look for cheaper analogues on AliExpress, but the quality may vary.

5. Voltage problems: when the socket is to blame

If the refrigerator Indesit turns on and immediately turns off for no apparent reasoncheck power supply quality. Low or unstable voltage can cause:

• ⚡ False protection alarms compressor.
• 🔌 Overheating start-up protection relay.
• 💡 Failures in the operation of the electronic board.

How to diagnose:

1. Connect the refrigerator to another outlet (preferably on a separate line).
2. Use voltage stabilizer (if in your area frequent surges).
3. Check the voltage in the socket with a multimeter:
   • Normal: 220-230 V.
   • Critical low: <190 V.
   • Critical high: >250 V.

⚠️

Attention: If the voltage in the network is constantly lower 200 V, this can lead to compressor overheating and its premature failure. In such cases, be sure to use a stabilizer!

6. Freon leak: when the refrigerator is “empty”

If the compressor is running, but the refrigerator is Indesit does not freeze and turns off after a few secondspossible refrigerant leak. This happens due to:

• 🕳️ Microcracks in the evaporator tubes (often at soldering points).
• 🔧 Corrosion copper tubes (in older models).
• 🛠️ Damage to the capillary tube when moving the refrigerator.

Signs of leakage:

• ❄️ The freezer does not cool, but the motor works.
• 🔊 The compressor hums louder than usual (trying to build up pressure).
• 🌡️ The condenser (grid at the back) does not heat up.

What do:

A freon leak cannot be eliminated on your own - you need special equipment (vacuum pump, refrigerant cylinder, soldering torch). If you suspect this problem:

1. Disconnect the refrigerator from the mains.
2. Do not turn it on until repaired - this may complete the compressor.
3. Call a technician for pressure testing of the system and refilling with freon.

⚠️

Attention: Do not try to refill the refrigerator with freon yourself! This is dangerous (risk of burns and poisoning) and requires certified equipment. Incorrect refueling can lead to explosion of the compressor.

7. Thermostat: when the “brain” of the refrigerator goes crazy

In mechanical models Indesit (for example, ST 167, TS 105) it is responsible for turning on the compressor thermostat. If it fails, the refrigerator can:

• 🔄 Turn on and off randomly.
• 🧊 Do not turn off at all (work without stopping).
• 🌡️ Do not respond to the handle adjustment.

How to check the thermostat:

1. Remove the temperature control knob.
2. Disconnect the wires from the thermostat (remember their location!).
3. Ring the contacts 3 and 4 (on most models Indesit):
   • At room temperature - contacts are open.
   • If you cool the sensor (for example, put it in the freezer for 10 minutes) - should close.

If the thermostat does not close the contacts when cooling, it needs to be replaced. Cost of the part: from 800 to 2500 rubles depending on the model.

FAQ: Frequently asked questions about malfunction

The Indesit refrigerator turns on for 5 seconds and turns off. What is it?
