Atlant refrigerator relay: where is it located, how to check and replace it yourself

Refrigerator owners Atlant sooner or later face with the need to find a relay - the key element responsible for starting the compressor. This part often fails due to voltage surges, wear or manufacturing defects, but finding it can turn into a real quest: depending on the model compressor start relay it can be hidden in different places. In single-chamber Atlantakh it is usually located next to the motor, and in double-chamber - sometimes even behind the rear wall.

The problem is aggravated by the fact that the manufacturer does not always adhere to a single placement scheme. For example, in models Atlant MXM 1705 the relay is mounted on the compressor bracket, and in Atlant XM 4021-000 it is hidden under a plastic cover at the bottom of the rear panel. If you've never disassembled a refrigerator, the search can take hours. This article will help save time: we have collected exact layout diagrams for popular models, signs of a relay malfunction and step-by-step instructions for checking it - with photos and explanations for beginners.

What is a relay in a refrigerator and why is it needed

A relay (or compressor start-up relay) is an electromechanical device that performs two critical functions:

• 🔌 Compressor start —supplies current to the motor winding at the moment of switching on, creating the necessary starting torque.
• 🛡️ Protection from overheating —turns off the power if the compressor winding begins to overheat (for example, when jammed or power surges).

Without a working relay, the refrigerator will either not turn on at all, or will work intermittently, constantly turning off after a few seconds. Modern models Atlant use two types of relays:

In Atlantakh with the system No Frost the relay is often integrated into the control board, which complicates its replacement. If your model is equipped with a display or electronic unit, Before disassembling, be sure to unplug the refrigerator for 10-15 minutes - this will release the residual charge in the capacitors and prevent electric shock.

Where is the relay located in Atlant refrigerators: diagrams for popular models

The location of the relay depends on refrigerator design (one- or two-chamber), year of manufacture and compressor type. Below are proven diagrams for the most common models. If your model is not on the list, use the general recommendations in the next section.

Single-chamber refrigerators (MX, MXM series)

• 📍 Atlant MXM 1705, MHM 1708: the relay is mounted on the compressor bracket (black plastic block with two terminals). To get there, remove the lower rear cover.
• 📍 Atlant MX 2824: the relay is hidden under a metal plate next to the motor. You will need a screwdriver with a Phillips bit.
• 📍 Atlant MX 2831: the electronic relay is built into the control board (located behind the top panel inside the camera).

Two-chamber refrigerators (XM, XT series)

• 📍 Atlant XM 4021-000: the relay is located in a niche under the freezer, covered with a plastic cover. Attached with latches.
• 📍 Atlant XM 6025: the electronic relay is located on the back wall, next to the compressor, but hidden under the thermal insulation (you need to carefully bend the insulation).
• 📍 Atlant XT 162-011: the combined relay is fixed on the compressor itself with a 10 mm bolt.

How to distinguish a relay from a thermostat?

Thermoregulator (or thermostat) usually has a capillary tube and is located inside the chamber (for example, on the top shelf). The relay is always located next to the compressor and connected to it with wires without tubes.

If your model is not listed, use the universal search algorithm:

1. Unplug the refrigerator and move it away from the wall.
2. Remove the lower rear cover (held by 2-4 screws).
3. Find the compressor - this is a black cylindrical block with tubes.
4. The relay will be attached to the compressor or located nearby (maximum 15–20 cm from it).

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

The relay fails gradually, and the first symptoms are often attributed to other problems (for example, a freon leak or a broken thermostat). Here exact signsthat the relay is to blame:

• ⚡ The refrigerator does not turn on at all (no clicks, the compressor is silent).
• 🔄 The compressor starts for 1-2 seconds and immediately turns off (cycle repeats every 5-10 minutes).
• 🔥 The relay body is hot to the touch (indicates a short circuit or overheating of the winding).
• 💥 When turned on, clicks are heard, but the compressor does not start (typical for electromechanical relays).
• 🌡️ The refrigerator freezes weakly, although the compressor works without stopping (the relay does not turn off the power when it overheats).

If you observe at least one of these symptoms, first check the relay this is one of the few parts that can be diagnosed and replaced without special equipment. However, before this, make sure that:

• 🔌 There is voltage in the socket (check with a lamp or other device).
• 🧊 The thermostat is not broken (turn the knob to maximum - if the compressor is working, the problem is not in the relay).
• ❄️ The compressor is not jammed (try turning its shaft manually - if it does not rotate, the motor needs repair).

How to check the Atlant refrigerator relay with a multimeter: step-by-step instructions

To diagnose the relay you will need multimeter (even the cheapest model will do) and a screwdriver. Follow the algorithm:

Disconnect the refrigerator from the mains|Remove the back cover|Find the relay and disconnect the wires from it|Remember or photograph the connection diagram

-->

Checking the electromechanical relay

1. Move the multimeter to resistance test mode (200 Ω).
2. Connect the probes to the relay terminals (usually they are marked as S and M or 1 and 2).
3. A working relay should show resistance 15–40 Ohm. If the device shows 0 (short circuit) or 1 (open circuit), the part is faulty.
4. Check the circuit between the terminals M and L (or 2 and 3). The resistance should be 0 Ohm (direct connection).

Checking an electronic (posistor) relay

Electronic relays are checked differently:

1. Measure the resistance between the terminals 1 and 2 at room temperature Normal: 20–100 Ohm.
2. Heat the relay with a hair dryer (up to 60–70°C) and re-measure the resistance. In a working relay, it should increase sharply (5-10 times).
3. If the resistance does not change or is equal 0/1, the relay is faulty.

Also inspect the relay visually:

• 🔍 Carbon deposits or melted contacts are a sign of a short circuit.
• 💧 Traces of moisture or corrosion (especially in electronic relays) is the cause of unstable operation.
• 🔧 Cracks in the housing or broken springs (in electromechanical relays).

How to replace a relay in an Atlant refrigerator with your own hands

Replacing a relay is one of the simplest repair operations, but it requires care. You will need:

• 🔧 Screwdriver (phillips or flat, depending on the model).
• 🔌 New relay (must match type, power and number of contacts).
• 📸 Camera (to fix the connection diagram).

Step-by-step instructions:

1. Unplug the refrigerator and turn it with the back wall towards you.
2. Remove the protective cover (if any) and find the relay.
3. Disconnect the wires from the relay, having previously photographed their location B Atlantakh The following markings are usually used:
   • L - phase (220V power supply).
   • N - zero.
   • S or Start - starting winding compressor.
   • M or Main —working winding.

Unscrew the relay from the bracket (usually it is secured with 1-2 bolts).

Install a new relay, connect the wires according to the diagram.

Secure the lid and turn on the refrigerator. If the compressor starts and works stably, the repair is complete.

What to do if after replacing the relay the refrigerator does not turn on?

1. Check if the wires are connected correctly (compare with the diagram).

2. that the new relay is compatible with your compressor model.

3. Measure the resistance of the compressor windings - the motor may have burned out.

4. Check the voltage in the outlet (should be 220–230V).

Cost of a new relay for Atlant varies from 500 to 2500 rubles depending on the type:

• Electromechanical (for example, RTK-X or DHR) - 600–1200 rub.
• Electronic (posistor, for example, 3TS-15K) - 1500–2500 rub.
• Combined (for example, RBM-1) - 1800–3000 rubles.

Common mistakes when replacing a relay and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here's what can't do when replacing a relay:

• ❌ Ignore contact markings. Connecting the phase (L) to the starting winding (S) instead of the working one (M) will damage the compressor in a few minutes.
• ❌ Use a relay from a different model. For example, a relay from Stinola is not suitable for Atlanta - different starting currents.
• ❌ Attach the relay "on weight". Vibration of the compressor can loosen the contacts, which will lead to overheating.
• ❌ Check the relay without loadIf you simply apply 220V to the relay. without a compressor, it will burn out.

Also pay attention to the following nuances:

In models Atlant with electronic control (for example, XM 6321), the relay can be soldered into the board. In this case:

1. Solder the faulty relay with a soldering iron (power no more than 40 W).
2. Install a new one, observing the polarity.
3. Check the circuit with a multimeter for a short circuit.

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

Theoretically, yes, but only if the problem is:

- Oxidized contacts (they can be cleaned with sandpaper).

- Broken spring (in electromechanical relays).

- Moisture inside the case (dry with a hairdryer).

However, in 80% of cases, repairs have a temporary effect, and after 1-3 months the relay fails again. Replacement is more reliable.

When you should not repair the relay yourself

Some breakdowns require intervention. Contact a service center if:

• 🔥 The relay burned out due to a power surge, and the control board was damaged along with it.
• ⚡ The compressor does not start even with a known good relay (possibly an interturn short circuit in the windings).
• 💻 A refrigerator with an electronic display gives an error (for example, E1 or F2).
• 🔌 After replacing the relay, the machine in the panel is triggered (short circuit in the circuit).

It is also worth considering that in refrigerators Atlant Over 15 years, replacing the relay may not be practical. If the compressor is worn out, it will create an increased load on the new relay, and it will quickly fail. In this case, it is more economical to buy a new refrigerator or replace the compressor.

FAQ: Frequently asked questions about relays in Atlant refrigerators

Can I use a relay from another refrigerator (for example, Indesit or Biryusa)?

Theoretically, it is possible, but only if they match:

• Type of relay (electromechanical/electronic).
• Rated current (indicated on the relay body).
• Quantity and purpose contacts.

For example, a relay from Indesit with marking RTK-H is suitable for Atlanta with a similar compressor. But it is better to buy an original spare part or an analogue recommended by the manufacturer.

How to test a relay without a multimeter?

If you don’t have a multimeter, you can use an incandescent lamp (220V, 40–60 W):

1. Connect the lamp in series with the relay (lamp → relay → compressor).
2. Plug in the refrigerator.
3. If the lamp lights up and goes out after 1-2 seconds, the relay is working. If the lamp is working. does not light up or lights up constantly - the relay is faulty.

Attention: this method is dangerous! Risk of electric shock. Use only as a last resort.

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

Cost of work (excluding spare parts) in 2026:

• Replacement of an electromechanical relay — 1000–1800 rub.
• Replacement of electronic relay — 1500–2500 rub.
• Replacement of a relay with soldering (if it is soldered into the board) - 2000–3500 rubles.

In the regions, prices may be 20–30% lower. Check the cost by phone - some services charge an additional fee for departure.

Why does a new relay burn out after a few days?

Most often this happens due to:

• Faulty starting capacitor (does not provide the required current for start).
• Problems with compressor windings (interturn short circuit).
• Voltage surges in the network (the relay is not designed for 250V+).
• Incorrect connections (confused S and M).

Before installing a new relay, check these elements!

Where to buy a relay for the Atlant refrigerator?

Original and compatible relays can be found:

• In branded service centers Atlant (6-12 month warranty).
• In stores of spare parts for household appliances (for example, 220 Volt, M-Video, Eldorado).
• On marketplaces (Yandex Market, Ozon, Wildberries) - but check the reviews!
• On Avito or Yule (a used relay is cheaper, but the risk of buying a faulty part is higher).

The average price of a new relay is 800–2000 rub..
