Replacing the relay in the Indesit refrigerator: instructions with photos and tips expert

Did the refrigerator Indesit stop freezing, does the compressor not start or work intermittently? In 60% of cases, the starting protection relay is to blame - a small but critical element of the system. Replacing it will cost 3-5 times less than calling a technician, if you know the nuances. This article will help you figure out how to independently diagnose the malfunctionto select an analogue of the original relay and install it without the risk of damaging the equipment.

We will analyze in detail:

• 🔍 How to distinguish a relay malfunction from a compressor failure or thermostat
• 🛠️ Step-by-step analysis of the refrigerator with photos of key stages
• ⚡ Typical replacement errors that lead to repeated breakdowns
• 💰 Where to buy a relay for Indesit and how not to run into fake

Important: the instructions are suitable for most models Indesit with compressors Embraco, Secop (formerly Danfoss) and LG, released after 2010. For older refrigerators (before 2005), the connection diagram may need to be adapted.

Signs of a relay malfunction: when it’s time to change

The relay in the refrigerator performs two functions: starts the compressor and protects it from overheating. When a breakdown occurs, the symptoms appear immediately - they cannot be ignored, otherwise the engine will burn out. Here are the key signals:

• 🔊 The compressor hums, but does not start (relay clicks are heard)
• ❄️ The refrigerator does not freeze, although the light bulb is inside lights up
• ⏱️ The motor runs for 5-10 seconds and turns off (the cycle repeats)
• 🔥 The relay body is hot to the touch (normal: up to 40°C)
• 💡 An error flashes on the panel F05 or E02 (for models with a display)

⚠️ Attention: If the compressor does not show signs of life (no hum, clicks), the problem may be a broken motor winding or a malfunction of the thermostat. Before replacing the relay be sure to check the resistance of the windings with a multimeter (norm: 20-40 Ohms for working, 10-20 Ohms for starting).

In 20% of cases the relay “sticks” due to voltage surges. If your network has frequent surges, after replacing, install voltage stabilizer - this will extend the life of the new relay by 2-3 times.

Types of relays in Indesit refrigerators: how not to make a mistake with the choice

In refrigerators Indesit they use three types of relays:

🔹 How to determine the type of relay of your refrigerator:

1. Find the sticker on the compressor (usually black or green).
2. Write down the motor model (for example, Embraco EGX 90HLC).
3. Check the markings on the body of the old relay (if it has been removed).

⚠️ Attention: Relays from compressors Secop (former Danfoss) and Embraco not interchangeable, even if they look similar in appearance!

If you are not sure about the choice, take the old relay to the store - the seller will select an analogue from the catalog. Popular replacements for the original relays Indesit:

• 🔧 DANFOSS 103N0010 - universal for compressors up to 1/4. hp
• 🔧 EMBRACO RSI 2,5 — for motors with a power of 70-120 W
• 🔧 LG L140-8 — for refrigerators with inverter compressors

How to check a relay without a multimeter?

If you don’t have a tester at hand, you can temporarily install a known working relay (for example, from another refrigerator). If the compressor starts, your relay is faulty. But remember: this method does not guarantee a 100% diagnosis, since the problem may be complex (for example, a malfunction + overheating of the motor).

Tools and preparation: what you will need for replacement

For work you will need:

• 🔧 Phillips and flat screwdrivers (size No. 2)
• 🔧 Pliers or side cutters
• 🔧 Multimeter (for checking contacts)
• 🔧 New relay (original or analogue)
• 🔧 Heat shrink tube or electrical tape
• 🔧 Flashlight (rear wall lighting)

Preparing the refrigerator:

1. Turn off the power and remove the plug from sockets.
2. Unload food from the freezer (if there is one).
3. Move the refrigerator from the wall 50-60 cm to access the compressor.
4. Take a photo of the location of the wires on the relay (useful for reassembly).

⚠️ Attention: Do not place the refrigerator on its side! Oil from the compressor may get into the pipes, which will cause the motor to jam. If you need to move the equipment, use a cart or an assistant.

Step-by-step instructions: how to remove and install the relay

Step 1. Dismantling the old relay

The relay is attached to the compressor using:

• 🔩 Rivets (in older models) - cut off with side cutters.
• 🔩 Screws (in new ones) - unscrew with a screwdriver.
• 🔩 Latch (in electronic relays) - carefully press out with a flat screwdriver.

Step 2. Disconnecting the wires

The wires on the relay are marked with letters:

• S — starting winding
• R — working winding
• C — common contact

Important: If there is no marking, refer to the photograph taken before disassembly. Connecting wires in the wrong sequence will damage the compressor!

Step 3. Installing a new relay

Action algorithm:

1. Attach the relay to the compressor (with a screw or latch).
2. Connect the wires according to the markings or photos.
3. Insulate the exposed contacts with heat-shrink tubing.
4. Check the reliability of the fastening - the relay should not dangle.

Step 4. Test run

After assembly:

1. Plug in the refrigerator.
2. Listen to the compressor: there should be a smooth hum without clicks.
3. Check the temperature the relay housing after 10 minutes - it should not heat up above 40°C.

📌 Note: If the compressor does not start, check:

• The correct connection of the wires
• The voltage in the socket (must be 220-230 V)
• Thermostat integrity (close contacts 3 and 4 - if the motor starts, the problem is in the thermostat)

Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes. Here TOP-5 errors when replacing a relay and their consequences:

⚠️ Attention: If after replacing the relay the compressor works, but the refrigerator does not freeze, the problem may be:

• 🔹 Freon leak (refilling required)
• 🔹 Clogged capillary tube (needs repair)
• 🔹 Control board malfunctions (in models with No Frost)

In such cases, it is better to contact a specialist - independent repairs without equipment can aggravate the breakdown.

Where to buy a relay for Indesit: prices and trusted suppliers

A new relay can be purchased:

• 🏬 Official service centers Indesit - 1 year warranty, but the price is 30-50% higher than the market.
• 🛒 Spare parts stores (for example, "220 Volt", "VseInstrumenty.ru") - average price 800-1500 rubles.
• 🌍 Online platforms (AliExpress, eBay- cheaper, but there is a risk of counterfeiting (especially for relays Embraco).
• 🔄 Used markets - only if the seller gives a guarantee (the relay is a consumable, and the old one may not last long).

Average prices for popular models (2026):

• Indesit 4812 300 20200 (RTK) - 1200-1800 rubles.
• DANFOSS 103N0010 - 900-1300 rubles.
• EMBRACO RSI 2,5 - 1500-2000 rubles.
• LG L140-8 — 2000-2500 rubles.

💡 Advice: Before purchasing, check the relay article number with the compatibility table on the manufacturer's website. For example, for compressors Embraco EGX a relay is suitable, and for RSI 2,5, and for Secop NL - only original Indesit 4812 300 20100.

⚠️ Attention: On AliExpress they often sell universal relays without markings. Such parts may not be suitable for current characteristics! Before purchasing, check with the seller:

• Maximum operating current (must match the parameters of your compressor).
• Type of fastening (screw or latch).
• Certificate of conformity.

Prevention: how to extend the life of the relay and compressor

The average service life of a relay is 5-7 years, but with proper operation it can be increased to 10-12 years. Here are 5 rules of prevention:

• ⚡ Use voltage stabilizer (especially in rural areas or old houses).
• 🧹 Once every six months, clean capacitor (grid on the back wall) from dust.
• 🔌 Do not connect the refrigerator through an extension cord - only directly into socket.
• 🕒 Avoid frequent switching on/off (the interval between cycles is at least 5 minutes).
• 🌡️ Do not place the refrigerator next to a stove or radiator (the maximum temperature around is 30°C).

📌 Useful life hack: If the refrigerator has not been used for a long time (for example, on cottage), before turning it on, let it stand for 2-3 hours in a vertical position. This will allow the oil to drain into the compressor and avoid a dry start, which is detrimental to the relay.

⚠️ Attention: If your region has hard water, rinse once a year drainage hole (at the bottom of the rear wall). Clogged drainage leads to increased humidity, which accelerates corrosion of the relay contacts.

FAQ: answers to frequently asked questions

Is it possible to replace the relay without disconnecting the refrigerator from the network?

No, this is deadly! and the relay contacts may be energized even when the thermostat is turned off. Always remove the plug from the socket before starting work.

How long does it take to replace the relay?

For an experienced technician - 20-30 minutes. If you are doing this for the first time, reserve 1-1.5 hours (including diagnostics and test run). hurry when connecting the wires.

What is the difference between a starting relay and a protective one?

A starting relay closes the circuit to start the compressor, and a protective one opens it for overheating or overload In most refrigerators Indesit these functions are combined in one housing (start-up relay).

Is it possible to repair the relay instead of replacing it?

Theoretically, yes - if the problem is oxidized contacts or a broken spring. But in practice, repairs are not cost-effective: the cost of a new relay is comparable to the price of diagnostics, and the reliability of the repaired part is 3-4 times lower.

Why does a new relay burn out after a week?

Reasons:

• 🔹 Malfunction compressor (interturn short circuit).
• 🔹 Incorrect wire connection.
• 🔹 Voltage surges in the network.
• 🔹 Overheating due to a clogged capacitor.

Check all elements circuit, especially if the relay burned out again.
