Independent dismantling of the Atlant refrigerator relay: step by step

The relay in the refrigerator Atlant is a small but critical element that is responsible for starting the compressor and protecting it from overloads. If your two-chamber unit suddenly stops freezing, makes strange clicks, or the compressor does not turn on at all, the problem may lie precisely in the start-up relay. Remove it yourself Even a beginner can do it if you strictly follow the instructions and follow safety precautions.

Many users are afraid to get into "insides" of the refrigerator, for fear of damaging expensive parts or getting an electric shock. However, in practice, the process of dismantling the relay takes no more than 15–20 minutes and does not require special skills. The main thing is to prepare properly, understand connection diagram and avoid common mistakes, which we will discuss below.

In this article you will find not only step-by-step instructions with photos, but also tips on diagnosing a malfunction, choosing a new relay, as well as answers to frequently asked questions. If after reading you still have doubts, it is better to contact a specialist, but in 80% of cases the problem is solved by replacing the relay without calling a specialist.

Preparation for work: tools and safety measures

Before you begin dismantling, make sure that you have everything you need on hand. Minimum set of tools to remove the relay from refrigerator Atlant includes:

• 🔧 Phillips and flathead screwdrivers (size depends on the model, usually No. 2)
• 📸 Phone or camera (for fixing the connection diagram)
• 🔌 Multimeter (to check the functionality of the relay and compressor)
• 🧤 Dielectric gloves (rubber with textile base)
• 🔦 Flashlight (lighting the back wall of the refrigerator)

Special attention take safety precautions. A refrigerator is an electrical appliance, and even when turned off, capacitors can retain a charge. Disconnect the unit from the mains 10-15 minutes before starting work so that all circuit elements are discharged. If you have a model with a system No Frost, wait until the evaporator is completely defrosted - this will simplify access to the compressor.

⚠️ Attention: Do not touch the metal parts of the refrigerator with wet hands. Condensation on the chassis can become a current conductor even if the power is turned off. Wipe the surfaces with a dry cloth before starting work.

If you have never dealt with electrical circuits, we recommend that you first study the relay structure. In refrigerators Atlant two-chamber type, a relay is most often installed RTK-X or RTP-1. Their design is different, but the mounting principle is the same. For clarity, you can watch a video analysis on YouTube according to your model - this will help to avoid mistakes when disconnecting wires.

Where is the relay in the Atlant refrigerator?

In two-chamber models Atlant the start-up relay is always located next to the compressor. To find it:

1. Move the refrigerator away from the wall (30-40 cm is enough).
2. Remove the lower back cover (it is attached to 2-4 screws or latches).
3. The compressor is a black “barrel” with tubes, and the relay is a small box (usually black or gray) attached to its body.

The photo below shows the typical location of the relay on models Atlant MXM 1705, Atlant MXM 2835 and similar ones. Please note that in some modifications the relay may be hidden under a plastic casing - it must be carefully removed by prying it with a screwdriver.

If you are not sure that you have found exactly the relay, check presence two or three wiresconnected to it. One of them goes from the plug (power), the second - to the compressor, the third (if any) - to the thermostat. Also on the relay body there should be a sticker with markings, for example: RTK-X 125V 50Hz or DANFOSS 103N0020.

How to distinguish a relay from a starting capacitor?

A capacitor is a cylindrical part (usually silver in color) without wires connected to terminals. The relay always has a housing with contacts and is attached directly to the compressor or next to it.

Step-by-step instructions: how to remove the relay from the compressor

When you have found the relay, you can begin dismantling. Follow this algorithm to avoid damaging the wires or fastenings:

Step 1. Disconnecting the wires

Take a photo of the diagram for connecting the wires to the relay. This will help you connect them back correctly. Gently pull each wire by the terminal (not the wire itself!). If the contacts are stuck, use a flat-head screwdriver to pry the retainer. Do not use excessive force —plastic connectors are fragile.

Step 2. Removing the relay mount

Relay attached to the compressor in two ways:

• 🔩 On bolts/screws - unscrew them with a Phillips screwdriver.
• 🔗 On a spring clamp - pry the latch with a screwdriver and move the relay to the side.

Step 3. Removal relay

After disconnecting the wires and fasteners, carefully remove the relay. If it “fits” tightly, do not pull it by force - check if there are any unnoticed latches left. In some models Atlant the relay may be glued to the compressor with thermal paste - in this case, carefully pry it around the perimeter.

⚠️ Attention: If, when removing the relay, you notice traces of melting on the wires or housing, this is a sign of a short circuit. In this case, before installing a new relay, be sure to check the compressor and power circuit with a multimeter.

How to check the removed relay for functionality

Before buying a new relay, make sure that the old one is really faulty. To do this you will need a multimeter. Check procedure:

1. Checking the power circuit

Switch the multimeter to resistance measurement mode (200 Ohm). Connect the probes to the relay contacts corresponding to the power input and output (usually they are marked as L and T or 1 and 2). Normal resistance is 10–30 ohms. If the device shows 1 (break) or 0 (short circuit), the relay is faulty.

2. Checking the starting winding

Connect the probes to the contacts L and S (or 1 and 3). The resistance should be between 30–50 ohms. Deviations indicate a malfunction of the trigger mechanism.

3. Visual inspection

Inspect the relay housing for cracks, melting or signs of overheating. If the contacts are blackened, this is a sign of an arc discharge - such a relay must be replaced.

Choosing a new relay: what to look for

Not all relays are suitable for refrigerators Atlant. Key parameters when choosing:

• 🔍 Relay type: For most models Atlant suitable relays RTK-X or RTP-1. For inverter compressors, specialized relays are needed (for example, Emerson or Secop).
• 📏 Dimensions: Dimensions must match the old relay (especially important for models with a dense layout).
• ⚡ Voltage and current: On the body of the old relay there is a marking, for example: 220–240V 50Hz 1.2A. The new relay must have identical or similar parameters.
• 🔧 Mounting type: Bolt or clamp. Some relays are universal, but it is better to choose an analogue.

If you are not sure of the choice, take the old relay to the store - the seller will help you choose a replacement. For refrigerators Atlant released after 2015, relays are often suitable. from Danfoss (series 103N) or Embraco (series EG). Cost varies from 500 to 1500 rubles depending on the type.

⚠️ Attention: Do not buy used relays or from unknown sites. Defective or worn parts can lead to failure of the compressor, the repair of which will cost 5-10 times more.

Installation of a new relay and testing performance

Installation of a new relay is performed in the reverse order:

1. Fast the relay on the compressor (with bolts or a clamp).
2. Connect the wires according to the diagram (use the photo taken before removal).
3. Make sure that everything the contacts are tightly fixed.
4. Install the protective casing (if there was one).

After installation, turn on the refrigerator and check:

• 🔊 Is there a characteristic click of the relay when starting up.
• 🌀 Whether the compressor begins to rotate (can be heard by a uniform hum).
• ❄️ Has the cold entered the chambers (10-15 minutes after switching on).

If the compressor does not start, turn off the power and check:

• The wires are connected correctly.
• Voltage in the socket (should be 220–230V).
• Resistance of the compressor windings (between contacts C-S and C-M should be 20–40 Ohms).

What to do if, after replacing the relay, the compressor works, but does not freeze?

The reason may be a freon leak, a clogged capillary tube, or a malfunction of the thermostat. In this case, diagnostics of the refrigeration circuit is required.

Typical errors when replacing the relay and how to avoid them.

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. The most common:

1. Incorrect connection of wires

If you mix up the wires, the relay may burn out the first time you turn it on. diagram or photograph. In refrigerators Atlant standard pinout:

• L (Line) - phase (usually brown or red wire).
• N (Neutral) - zero (blue or black).
• S (Start) - starting winding (yellow, orange or white).

2. Using an incompatible relay

Relays from Stinol or Indesit refrigerators are not suitable for Atlant due to different current characteristics. Even if it is physically suitable for mounting, this will lead to overheating or failure of the compressor.

3. compressor

If the relay burns out due to an interturn short circuit in the compressor, the new relay will last for several days at most. Always check the resistance of the compressor windings before installing a new relay.

4. Careless handling of wires

Wires in the refrigerator. often become fragile over time. Do not pull them by the wires - only by the connectors. If the wire is broken, use terminal blocks for connection (twisting with electrical tape is unacceptable!).

FAQ: Frequently asked questions about replacing the relay in the Atlant refrigerator

Is it possible to repair the relay or just replace it?

In 90% of cases, the relay cannot be repaired, since its body is sealed and the internal contacts wear out. The exception is if the problem is in oxidized terminals (they can be cleaned with sandpaper). But even after cleaning, the relay rarely lasts long, so it is better to replace it immediately.

What multimeter is needed for testing?

Any one will do. digital multimeter with a mode for measuring resistance (ohmmeter) and voltage (voltmeter). For example, DT-830B or Mastech MY64. The main thing is that it shows values ​​up to 200 Ohms with an accuracy of ±1%.

How long does it take to replace a relay?

For beginners - 30–40 minutes (including photographing the circuit and testing). An experienced technician will do it in 10–15 minutes. If you have to go to the store for a new relay, the process will take 1–2 hours.

What to do if, after replacing the relay, the refrigerator works, but gets very hot?

This may be a sign:

• Thermostat malfunction (does not turn off the compressor).
• Freon leaks (the compressor runs idle).
• Condenser contamination (dust on the grille at the back).

Check the temperature of the condenser - if it is hot, but there is no cold, call a technician.

Where to buy a relay for Atlanta if there are no spare parts in the city?

Options:

• Order in online stores (220-Volt, All-Zap, Beru).
• Contact the service center Atlant —they often sell original spare parts.
• Buy a used relay at Avito or Yule (risky, but cheaper).

When ordering online check compatibility with your refrigerator model.
