The refrigerator Nord stopped freezing, the motor hums but does not start, or the compressor suddenly turns off after a few seconds of operation? With an 80% probability, the problem lies in starting or protective relay a small block that is responsible for starting the compressor and protecting against overheating. It is not difficult to find, but the location depends on the model and year of manufacture of the equipment.
This article contains detailed diagrams with photos of exactly where the relay is installed in popular series Nord (from old Soviet models to modern ones NRF, NRT, NRB). We will also look at how to distinguish a faulty relay from a burnt-out compressor, what tools are needed for diagnostics, and what to do if after replacing the refrigerator still does not work. In 95% of cases, the relay Nord is attached directly to the compressor - it is easy to identify by its black plastic case with wires and a characteristic click upon startup.
Why the relay breaks in the Nord refrigerator: the main reasons
The relay is the “weak link” in the compressor power circuit. It fails more often than the motor itself, due to:
- 🔥 Voltage drops - surges in the network above 240V burn the relay coil winding. Models older than 2010 without a stabilizer are especially vulnerable. Nord older than 2010 without stabilizer.
- ❄️ Compressor overheating - if the refrigerator operates without stopping due to a freon leak or a clogged capillary tube, the relay switches off too often and wears out.
- 🕰️ Natural wear —the average service life of the relay Nord 5–7 years. In older models (for example Nord-210 or Nord-231) it can last up to 10 years, but requires preventive cleaning of the contacts.
- 💧 Contact corrosion —moisture from condensation or leaks leads to oxidation of metal parts inside the relay.
The first sign of a malfunction is the compressor does not start, although the light in the refrigerator is on and the relay click is heard. Or the motor turns on for 1-2 seconds and immediately turns off. In rare cases, the relay “sticks” and the compressor works without stopping, which leads to its overheating.
Where the relay is located in the Nord refrigerator: diagrams for different models
In most refrigerators Nord the relay is located at the back, on the compressor - this is a black or gray plastic box the size of a pack of cigarettes, to which 2-3 wires fit. But there are nuances depending on the series:
1. Modern models (2010–2026): NRF, NRT, NRB series
In refrigerators with a system No Frost (NRFand drip defrosting (NRT), the relay is secured directly to the compressor housing using a spring clip or screw. It is easy to identify by:
- 🔌 Two terminals for connecting wires (phase and zero).
- 🔊 A characteristic click when turning the refrigerator on/off.
- 📏 Dimensions: approximately 5x4x3 cm (may vary depending on the power of the compressor).

On the compressor (black box on the right) you can see the start relay with connected wires. Usually it is closed with a protective cover, which must be removed by snapping the clamps.
2. Old models (before 2010): Nord-210, Nord-231, Nord-243
In Soviet and early Russian refrigerators Nord the relay may be:
- 🔧 Built into the compressor (for example, in models with motor DXM-3 or DXM-5). In this case, it is hidden under a metal cover on the compressor housing.
- 📦 Moved separately —in a plastic box next to the compressor (typical for models Nord-243 i Nord-262).
To get to the relay in older models, sometimes you have to remove the back cover of the refrigerator or even dismantle compressor. Pay attention: in refrigerators Nord before 2000, the relay is often combined with starting capacitor —they are changed together.
Disconnect the refrigerator from the mains
Remove the back panel (if the relay is not immediately visible)
Prepare a flashlight to inspect the compressor
Check the wires for presence melting-->
3. Models with an inverter compressor (NRF-Inverter series)
In refrigerators Nord with an inverter motor (for example, NRF-167WI) there is no separate relay - its functions are performed by an electronic control unit. If such a refrigerator does not turn on, there is a problem may be in:
- 🔌 Power supply (on the control board).
- 📱 Electronic module (diagnostics with a tester is required).
- 🔋 Capacitors on the board (swollen or leaking).
⚠️ Attention: If your refrigerator Nord with an inverter compressor, do not try look for the relay in the usual place - it is not there. It is better to entrust the diagnosis and repair of such models to a specialist, since soldering equipment and knowledge of the board circuit are required.
How to check the Nord refrigerator relay with a multimeter
Before changing the relay, make sure that this is the problem. You will need multimeter (or a tester) and a screwdriver. Follow the step-by-step instructions:
- Disconnect the refrigerator from the compressor. network and remove the relay from the compressor. Usually it is attached to a latch or one screw.
- Inspect the body for melting, cracks or traces of burning. If there are any, the relay must be replaced.
- Ring the contacts with a tester:
- 🔋 Relay coil: measure the resistance between coil terminals (usually 10–50 Ohms). If the device shows an open circuit (∞) or a short circuit (0), the relay is faulty.
- 🔌 Contact: in normal condition, the resistance between them should be close to 0. If the device shows an open circuit, the contacts are burnt.
If the relay is working properly, but the refrigerator does not work, the problem may be:
- 🔌 Compressor (ring the windings).
- 📉 Thermostat (check the circuit with a multimeter).
- 🔌 Wiring (inspect for melting).
Table: Relay compatibility for Nord refrigerators
Not all relays are suitable for different models Nord. Below is a compatibility table for popular series. If your model is not on the list, focus on compressor type (indicated on the sticker on the back of the refrigerator).
| Refrigerator model | Type compressor | Suitable relay (article) | Notes |
|---|---|---|---|
| Nord NRF-120, NRF-140 | L65, L85 | RTK-X, RTP-1, DHR-1M | Suitable relays from Atlant and Stinol similar models |
| Nord NRT-186, NRT-208 | L105, L120 | RTK-L, DHR-2 | Can be replaced with a relay from Biryusa-18 |
| Nord-210, Nord-231 | DXM-3, DXM-5 | RT-1, RT-2 (Soviet model) | Replacement is often required along with the capacitor |
| Nord NRB-100, NRB-120 | L55, L60 | RTK-M, DHR-1 | Suitable relay from Minsk-15M |
⚠️ Attention: When purchasing a new relay, be sure to check rated current (indicated on the body of the old one relay). For example, for a compressorL85a relay of 1.5–2.5 A is suitable, and forL120a current of 3–4 A is needed. A discrepancy will lead to repeated breakdown.
How to replace a relay in Nord refrigerator: step-by-step instructions
If the diagnostics confirmed a faulty relay, you can replace it yourself in 15–20 minutes. You will need:
- 🔧 Phillips screwdriver.
- 🔌 New relay (check compatibility in the table above).
- 📸 Camera (to take a photo of the wire connection diagram).
Order action:
- Disconnect the refrigerator from the network and turn it with the back wall towards you.
- Remove the protective cover compressor (if any). It is secured with latches or one screw.
- Take a photo of the wire connection to the relay. This will help not to confuse them during reassembly.
- Disconnect the wires (remember or mark which one went where).
- Remove the relay:
- If it is on a clamp, carefully snap it off with a screwdriver.
- If it is on a screw, unscrew the fastener.
If after replacing the relay the refrigerator turns on, but does not freezes, possible reasons:
- 🔌 Incorrect connection of wires (check in the photo).
- 📉 The thermostat or temperature sensor is faulty.
- ❄️ Freon leak (refill required).
Common mistakes when replacing relays and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here's what you cannot do when replacing a relay in a refrigerator Nord:
- ⚡ Connect the relay without checking the compressor. If the motor is stuck, the new relay will burn out within a few minutes. First, make sure that the compressor is working (check the windings).
- 🔌 Use a relay from other equipment (for example, from a washing machine or air conditioner). Even if it looks similar, the parameters may not match.
- 📸 Do not fix the connection diagram. Without a photograph, it is easy to mix up the wires, which will lead to a short circuit.
- 🔧 Tightening the relay mounting screws too tightly. This can damage the housing or dislodge the contacts inside.
Another common problem is between the relay and the compressor. If after replacement the refrigerator operates unstable (it turns on and off), check: poor contact between the relay and the compressor. If after replacement the refrigerator operates erratically (it turns on and off), check:
- 🔌 Reliability of fastening the relay to the compressor (it should fit tightly).
- 🔧 Cleanliness of the contacts (if necessary, clean them with emery cloth paper).
- 📏 The length of the wires - they should not be stretched.
Where to buy a relay for a Nord refrigerator and how much does it cost
A new relay can be purchased:
- 🏬 In stores of spare parts for refrigerators (for example, "Rembyttekhnika", "Holod-Master").
- 🛒 On marketplaces (Wildberries, Ozon, Yandex Market - search by article).
- 🔧 In service centers (sometimes they sell used relay after repair).
The cost depends on the type of relay:
- 💰 Regular starting relay (RTK-X, DHR-1) - 300–600 rubles.
- 💰 Protective relay with a temperature sensor (RTP-1) - 500-900 rubles.
- 💰 Relay for inverter compressors - 1000-1500 rubles (sold only complete with a control board).
⚠️ Attention: When buying relays on marketplaces, pay attention to reviews - you often come across fakes with low-quality contacts that burn out after 1-2 months. It is better to buy from trusted spare parts stores.
If you are not sure of the choice, take the old relay with you - the seller will help you choose an analogue. You can also order a relay by refrigerator serial number (indicated on the nameplate on the back).
FAQ: Frequently asked questions about the relay in the Nord refrigerator
Is it possible to repair the relay yourself without buying new?
In most cases, the relay cannot be repaired, since its body is sealed, and the internal parts (coil, contacts) wear out irreversibly. However, if the problem is oxidized contacts, they can be cleaned with sandpaper (fine grit) and temporarily bring the relay back to life. But this is a solution for 1-2 months - then the fault will return.
The Nord refrigerator clicks, but does not turn on. Is this really a relay?
Not always. Clicking sounds may indicate:
- 🔌 Faulty relay (the most common cause).
- 📉 Burnt out compressor (if the windings are broken).
- 🔋 Discharged or swollen capacitor (check it multimeter).
To accurately determine the culprit, you need to ring all the elements of the circuit.
After replacing the relay, the refrigerator works, but the compressor gets very hot. What to do?
This is a sign that:
- 🔥 The relay does not fit the parameters (the current is too high).
- 📉 The compressor is wearing out due to a freon leak or a clogged capillary tube.
- 🔌 The wires are connected incorrectly (phase and zero are reversed).
Disconnect the refrigerator and check compressor housing temperature - if it is hot (more than 60°C), you need to diagnose the cooling system.
Is the relay from the Atlant to Nord refrigerator suitable?
In most cases yesif the models are equipped with the same compressors (for example, L85 or L105). Relays from Atlant, Biryusa or Stinol with the same parameters (current, voltage) are interchangeable. The main thing is the match type fastening (clamp or screw) and contact location.
How long will the new relay last?
Service life depends on:
- 📊 Quality of the part (original or analogue).
- ⚡ Stability voltage in the network (during surges, the relay wears out faster).
- 📉 Compressor conditions (if the motor is worn out, the relay will operate more often).
On average, a new relay lasts 5–7 years. To extend its life, use voltage stabilizer and clean the contacts from dust once a year.
