Refrigerators Atlant are famous for their reliability, but even they are not immune to breakdowns. One of the common problems is the malfunction of the start-up relay - the part responsible for starting the compressor. If your unit suddenly stops freezing, makes clicking noises without starting the motor, or operates intermittently, the relay may be the culprit. In this article we will analyze how to remove the relay from the Atlant refrigerator with our own hands, without damaging other components, and will provide a video with a visual demonstration of the process.
It is important to understand: the dismantling procedure varies depending from models (MHM 1708, XM 4021, NRM 6026 etc.) and relay type (inductive or electronic). We will look at universal steps that are relevant for 90% of the brand’s household refrigerators, and also point out the nuances for specific series. If you have never dealt with electrical components, it is better to entrust the work to a master - but if you have minimal skills and tools, the task is quite feasible.
Before you begin, check: is the problem really in the relay? Sometimes similar symptoms are caused by a faulty thermostat, compressor, or freon leak. For diagnostics, you can use a multimeter (ring the contacts) or temporarily install a known working relay. If the diagnosis is confirmed, we proceed to dismantling.
Preparation: tools and safety measures
To remove the relay you will need:
- 🔧 Phillips screwdriver (usually PH2) - for unscrewing the fastenings of the compressor and casing.
- 🔌 Flat screwdriver —to pry the latches or disconnect the contacts.
- 📸 Smartphone —take a photo of the wire connection diagram before disconnecting!
- 🧤 Dielectric gloves — protection against accidental electric shock (even if the refrigerator is turned off).
- 🔍 Flashlight - illumination of the back of the refrigerator.
Safety first:
⚠️ Attention: Before work unplug the refrigerator and wait until the capacitors are discharged (10–15 minutes). Do not touch the compressor immediately after switching off - it may be hot (up to 90°C).
If your Atlant is equipped with an electronic control unit (models with a display, for example, MHM 2835-90), additionally disconnect the power cable from the board. Otherwise, you risk burning the microcircuits with a static discharge.
Localization of the relay: where to look for the part in the Atlant refrigerator
The relay is always located next to the compressor - metal "barrel" at the bottom of the rear wall. However, its appearance and fastening depend on the model:
| Refrigerator series | Relay type | Mounting location | Features |
|---|---|---|---|
| MHM (single-chamber) | Induction (black plastic case) | On the compressor, under a metal casing | Fixed with a screw or latch |
| HM, NRM (double-chamber) | Electronic (rectangular block) | On a bracket next to the compressor | Connected through connectors, not with screws |
| New line (2020+) | Hybrid (combined) | Inside the plastic box on the compressor | Requires removal of the box cover |
In models with the system No Frost (for example, ATLANT XM 6025-031) the relay can be hidden under additional thermal insulation. Carefully remove it without damaging the aluminum tape. If you are not sure about the location, watch the video for your series (see links at the end of the article).
Step-by-step instructions: how to remove the relay from an Atlant refrigerator
Let's consider the process using the example of a popular model Atlant MHM 1708-80 s induction relay. For other series, the steps are similar, but the fastening details may differ.
Unplug the refrigerator from the outlet
Take a photo of the wire connection
Wait 15 minutes for discharge capacitors
Prepare tools and lighting
Wear dielectric gloves-->
Step 1. Access to the compressor
Move the refrigerator away from the wall (at least 50 cm) and remove the bottom decorative panel, if any. In models without a panel, the compressor is immediately visible - it is a black cylinder with tubes. The relay is attached to it from the side or from above.
Step 2. Disconnecting the wires
Carefully pull the wire connectors going to the relay. If they are “stuck”, do not pull - use a flat screwdriver to pry the latch. Do not pull the wires themselves - you can damage the contacts inside the connector!
Carefully inspect the terminals: on some relays Atlant they are marked with letters:
S— starting winding,R—working winding,C—general contact.
Remember or write down their location - during reassembly, mixed up wires can damage the compressor.
Step 3. Removing the relay
Depending on the type of fastening:
- 🔩 If the relay is fixed screw —unscrew its cross with a screwdriver.
- 🔗 If it is held on latch —press it with a screwdriver and pull the relay up.
- 🧩 If the relay is inserted in grooves (electronic models) - pull the edges evenly until it comes out of the socket.
Step 4. Check and replacement
After removal, inspect the relay for melted contacts, cracks or a burning smell. If the part appears to be in good working order, check it with a multimeter (instructions in the next section). To replace, use a similar relay model —for example, for Atlant MHM suitable RTK-KhM or RTP-1.
What to do if the relay is “stuck” to the compressor?
If the relay cannot be removed due to oxidation or corrosion, do not apply force - you risk breaking the compressor mount. Spray the joint with WD-40, wait 10 minutes and try again. As a last resort, carefully pry the relay with a screwdriver, resting against its body and not against the contacts.
Video instructions: selection for different Atlant models
Theoretical knowledge is good, but a visual demonstration simplifies the task significantly. Below is a selection of proven videos with step-by-step analysis for popular series:
- 🎥 Atlant MXM (single-chamber): [Video with dismantling the induction relay] - shows the process of removing the casing and disconnecting the wires.
- 🎥 Atlant XM/NRM (two-chamber): [Video on replacing an electronic relay] - emphasis on connectors and testing with a multimeter.
- 🎥 New models (2020+): [Review of a hybrid relay] - how to remove the protective box without damage.
Please note: non-standard tools are often used in the video (for example, pliers instead of a screwdriver). We recommend following our checklist - this minimizes the risk of damage to parts.
⚠️ Attention: In some videos, the authors suggest “ringing” the relay without disconnecting from the compressor. It's dangerous! Even when turned off, capacitors can store a charge. Always remove the relay before checking.
How to check the Atlant refrigerator relay with a multimeter
The removed relay must be diagnosed to make sure it is faulty. To do this, you will need a multimeter in resistance test mode (200 Ω). Follow the algorithm:
1. Checking the working winding circuit
Connect the probes to the contacts R i C (markings on the relay body). A working relay will show resistance 15–40 Ohm. If the screen 0 (short circuit) or 1 (break) - the part is faulty.
2. Checking the starting winding
Measure the resistance between S and C. Normal values are 30–60 Ohm. Deviations indicate a breakdown or break.
3. Turn-to-turn short circuit test
Set the multimeter to mode 2000k Ω and check the resistance between S and R. In a working relay, it should tend to infinity (1 on the screen). Any final value is a sign of breakdown.
If the relay is electronic (a rectangular block with a microcircuit), checking it is more difficult. You will need:
- Ring power transistor (usually marked
Q1). - Check varistor (protective element against power surges).
- Inspect soldered contacts on the board - cracks or peeling indicate a malfunction.
Typical errors when removing a relay and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns. Here are the most common:
- ⚡ Working under voltage - can lead to electric shock or burning of the control board. Always remove the plug from the power supply. sockets!
- 🔌 Mixed wires —if you connect the starting winding instead of the working one, the compressor will not start or will burn out. Use a photo of the circuit.
- 🔧 Too much force —when dismantling a “stuck” relay, you can break the compressor mount. Use. WD-40.
- 📱 Ignoring markings - relay from Stinola or Indesita is not suitable for Atlanta even with a similar design.
Another common mistake is failure to check the new relay before installationEven a part purchased in a store can be wrong. defective. Always test it with a multimeter before installation.
If after replacing the relay the refrigerator does not work:
- Check thermostat - it may not give a start signal.
- Inspect compressor - if it hums but does not start, the problem may be an inter-turn short circuit.
- Make sure that mains voltage stable (220V ±10%).
Where to buy a relay for the Atlant refrigerator and how much does it cost
The cost and availability of spare parts depend on the type of relay and the region. Here are the estimated prices for 2026. year:

⚠️ Attention: When purchasing a relay on the secondary market, check its functionality with a multimeter. Defective parts will not be accepted back!
FAQ: Frequently asked questions about removing the Atlant refrigerator relay
Is it possible to remove the relay without disconnecting the refrigerator from network?
No! This is extremely dangerous. Capacitors in the compressor circuit can retain a charge even after turning off the power. Always remove the plug from the socket and wait 10-15 minutes before starting work.
How to understand that it is the relay that is broken and not the compressor?
If the relay is faulty. the compressor either does not start at all, or tries to start (clicks are heard), but immediately turns off. If the compressor hums, but does not freeze, the problem may be a freon leak or an interturn short circuit of the windings.
What to do if after replacing the relay the refrigerator does not turn on?
Check:
- The correct connection of the wires (check the photo).
- The voltage in the socket (should be 220V ± 10%).
- The functionality of the thermostat (check it with a multimeter).
If everything is in order, but the refrigerator does not work, it is possible the compressor is faulty.
Is it possible to repair the relay yourself?
Induction relays cannot be repaired - only replacement. Electronic ones can sometimes be restored (replacing a transistor, varistor), but this requires soldering and diagnostic skills. In 90% of cases, it is cheaper and more reliable to buy a new one.
How long does it take to replace a relay?
If you have the tools and experience - 20-40 minutes. Beginners may need up to 1-1.5 hours, especially if the relay is “stuck” or the wires are tightly seated in the connectors.
