How to replace the Atlant refrigerator relay: originals, analogues and life hacks for repairs

The refrigerator relay Atlant is a small but critical part that is responsible for starting the compressor and protecting against overloads. When it fails, the refrigerator either stops freezing or works intermittently: it hums, but does not turn on, or turns off a few seconds after starting. In service centers, they charge from 2,500 to 5,000 rubles for replacing a relay - but if you wish, you can save by choosing a suitable analogue and installing it yourself.

The problem is that the original relays are for Atlanta (for example, RTK-X or RT-3) are not always available, especially for older models. In addition, their price is sometimes too high - up to 1,800 rubles per part, which can be replaced with a universal option for 500–800 rubles. In this article we will look at which relays are suitable for refrigerators Atlant of different series, how to select them according to parameters and what to do if no analogues are suitable.

1. Original relays for Atlant refrigerators: where to buy and how much they cost

If you prefer to install “original” parts, start your search with original relays from the manufacturer. For refrigerators Atlant most often used:

• 🔹 RTK-X —start-up protection relay for models Atlant with compressors DXM-5, DXM-6 (for example, Atlant MXM 1705, Atlant XM 4021).
• 🔹 RT-3 — suitable for compressors DHR i DH series (for example, Atlant XM 6025).
• 🔹 RTP-1 —temperature relay, often fails in models with mechanical control.

You can buy original relays:

• 🛒 In branded service centers Atlant (warranty for the part, but the price is 20-30% higher than the market price).
• 🛒 On AliExpress or eBay - cheaper, but the risk of running into a fake (check the seller's reviews!).
• 🛒 In refrigerator spare parts stores (for example, 220-Volt, All-Zap).

The cost of original relays varies:

⚠️ Attention: Original relays for Atlanta are often counterfeited. When purchasing, check for a hologram on the packaging and check the catalog number with the official website of the manufacturer.

2. Universal relays: which ones are suitable for Atlanta

If the original relay could not be found or its price seems too high, you can use universal analogues. The main thing is to choose the right part. data-i="111">and operation current And compressor type.

For refrigerators Atlant the following universal relays are suitable:

• 🔧 Danfoss 103N0210 — suitable for compressors with a power of up to 140 W (for example, Atlant XM 4026). Price: 600–900 rubles.
• 🔧 Embraco EGX 100 —universal relay for compressors Embraco i Secop, but compatible with some models Atlanta (for example, with a compressor DXM-3Price: 700–1,100 rubles.
• 🔧 Sensata KLIXON 3MP —protects against overheating, suitable for compressors with a current of up to 1.5 A. Price: 500–800 rubles.
• 🔧 Thermik TR 150 —budget option for low-power compressors (up to 120 W). Price: 400–600 rubles.

Before purchasing a universal relay, check:

Compatibility with the type of refrigerant (R134a or R600a)

Maximum operating current (indicated on the body of the old relay)

Dimensions and mounting (must match the original)

Presence of overheating protection (thermal fuse)-->

Critical! If your refrigerator Atlant operates on refrigerant R600a (isobutane), the universal relay must be compatible with this type freon - otherwise there is a risk of fire!

3 How to select a relay according to the parameters. compressor

If you do not know the model of your relay or want to be sure of compatibility, focus on the compressor parameters. They are indicated on its body (usually a sticker on the side or top).

Main characteristics that are important for selecting a relay:

• 📌 Compressor model (for example, DXM-5-160).
• 📌 Power (W) —determines the relay operation current.
• 📌 Type refrigerant (R134a or R600a).
• 📌 Start current (A) —usually indicated as LRA (Locked Rotor Amps).

Example of decoding compressor sticker Atlant:

DXM-5-160
R134a
P = 140 W
LRA = 4.2 A

A relay with:

• 🔹 Maximum current at least 4.2 A is suitable for such a compressor data-i="160">🔹 Refrigerant support.
• 🔹 Refrigerant support R134a.
• 🔹 Compatibility with compressors of the DXM series.

⚠️ Attention: If the compressor label indicates a current LRA above 5 A, universal the relay may not be suitable - you will need an original or specialized one (for example, Danfoss 103N0240).

How to find the sticker with the compressor parameters?

Usually it is located on the back wall of the refrigerator, on the black cylindrical body of the compressor. If the sticker has worn off, try to find the refrigerator model in the documentation and search for compressor characteristics on the Internet.

4. Top 3 relay analogues for popular Atlanta models

We analyzed reviews of refrigerator masters and owners Atlant and compiled a list of proven analogues for the most common models.

For models with a compressor Secop (Danfoss) (for example, Atlant NRM 1631) a relay is suitable Embraco EGX 100 —it is fully compatible in connectors and current.

If your model is not in the table, use spare parts catalog on the website Atlant or check the compressor parameters as described in the previous section.

5. Step-by-step instructions for replacing the relay

You can replace the relay in the refrigerator Atlant on your own if you follow the instructions. You will need:

• 🔧 New relay (tested for compatibility).
• 🔧 Phillips screwdriver.
• 🔧 Multimeter (for checking contacts).
• 🔧 Pliers (if the fastening is tight).

Step 1. Unplug the refrigerator and let it stand for 10-15 minutes - this will discharge the capacitors.

Step 2. Remove the compressor protective casing (usually it is attached to 2-4 screws on the back refrigerator).

Step 3. Disconnect the relay from the compressor:

• 🔌 Carefully remove the terminals from the contacts (memorize or photograph their location!).
• 🔌 Unscrew the relay from the compressor housing (usually 1-2 screws).

Step 4. Install a new relay:

• 🔧 Screw it in place of the old one.
• 🔧 Connect the terminals in the same OK.
• 🔧 Check the reliability of the fastening - the relay should not be loose.

Step 5. Turn on the refrigerator and check the operation:

• 🔊 The compressor should start without clicks and a long rumble.
• 🔊 After 5-10 minutes, check whether the refrigerator is freezing.

⚠️ Attention: If, after replacing the relay, the compressor does not start or the protection is triggered (the relay clicks and turns off), check:

• 🔹 Correct connection of the terminals.
• 🔹 Compatibility of the relay with the compressor current.
• 🔹 Integrity of the compressor windings (check with a multimeter).

How to check the compressor multimeter?

Set the multimeter to resistance measurement mode (200 Ohm). Touch the compressor contacts with the probes:

- Between C (common) and S (starting winding) the resistance should be ~20–40 Ohms.

- Between C and R (working winding) — ~10–20 Ohm.

- Between S and R —the sum of the two previous values (~30–60 Ohms).

If the readings are different or infinity, the compressor is faulty.

6. What to do if no relay fits

There are situations when neither the original nor the universal relay starts the compressor. The reasons may be different:

• 🔋 Faulty compressor (jammed, broken winding).
• 🔌 Electrical problems (thermostat burnt out, damaged wiring).
• ❄️ Freon leak —the compressor cannot gain pressure.

How to diagnose the problem:

1. Ring the compressor with a multimeter (instructions in the spoiler above).
2. Check the thermostat: when turning the knob temperature adjustment, a click should be heard.
3. Inspect the wiring for melting or breaks.

If the compressor is faulty, you can:

• 🔧 Repair (replacing windings, oil - expensive, but cheaper than a new compressor).
• 🔧 Replace with a new one (price from 5,000 to 12,000 rubles depending on the model).
• 🔧 Buy used worker (risky, but cheaper).

⚠️ Attention: If the cause is a freon leak, independent repair is dangerous! R600a (isobutane) is explosive, and R134a requires special equipment for refueling. Contact a specialist!

7. Common mistakes when replacing relays and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here are the most common:

• ❌ Incorrect terminal connection - if you mix up S (starting) and R (working) windings, the compressor will not start or will burn out.
• ❌ Using a relay with a lower current —leads to overheating and shutdown of the compressor.
• ❌ Ignoring the compressor check —if it is faulty, the new relay will quickly fail.
• ❌ Poor relay fastening - vibration can break the contact.

How to avoid problems:

Make sure the terminals are connected correctly (check with diagram)

Check the relay fastening - it should not wobble

Measure the resistance of the compressor windings

Make sure that the new relay is compatible with the refrigerant -->

If after replacing the relay the refrigerator is unstable (often turns off, does not freeze), check:

• 🔹 System pressure —may need to refill freon.
• 🔹 Thermostat —if it is faulty, the compressor will work without stopping or will not turn on.
• 🔹 Capacitor —if it is swollen, it needs to be replaced.

FAQ: Answers to common questions questions

Is it possible to install a relay from another refrigerator (for example, from Indesit or Biryusa)?

Theoretically it is possible, but only if they match:

• 🔹 Operation current (LRA).
• 🔹 Type refrigerant.
• 🔹 Fastening and connectors.

For example, a relay from Biryusy with a compressor DXM-5 is suitable for Atlanta with the same compressor But better. use proven analogues from this article.

How to understand that it is the relay that has burned out, and not the compressor?

Signs of a faulty relay:

• 🔊 The refrigerator hums, but does not start (the compressor does not start).
• 🔊 The relay clicks and turns off after 1-2 seconds.
• 🔊 There is no voltage on the compressor contacts when turned on.

If the compressor does not hum at all, the problem may be in the thermostat or a broken winding.

How much does it cost to replace a relay in a service center?

The cost of work depends on the region and complexity:

• 💰 Replacing a relay - 1 500–3,000 rubles.
• 💰 Diagnostics + replacement - 2,500–5,000 rubles.
• 💰 If a compressor replacement is required - from 8,000 rubles.

In provincial cities, prices are lower by 20–30%.

Is it possible to repair the relay yourself?

In most cases, the relay is not repaired, but replaced - it consists of springs, contacts and a bimetallic plate, which wear out. However, sometimes it helps:

• 🔧 Cleaning the contacts (if they exist). oxidized).
• 🔧 Replacing the thermal fuse (if it has blown).

But such a repair is temporary - it is better to install a new relay.
