Replacing the start relay of the Atlant refrigerator: instructions with photos and tips

The starting relay is a small but critical element of the refrigerator Atlant, which is responsible for starting the compressor. When it fails, the unit either stops turning on or works intermittently, which leads to food spoilage and increased energy consumption. Replacing a relay is one of the few breakdowns that you can deal with yourself, without resorting to the services of a specialist. However, for this you need to clearly understand the principle of operation of the unit, be able to diagnose a malfunction and follow safety precautions.

In this article we will analyze all stages of replacement from checking the relay with a multimeter to installing a new part. We will pay special attention to models with compressors Atlant with compressors Danfoss and Secop, since their design has nuances. You will also learn how to distinguish a relay malfunction from problems with the thermostat or the compressor itself, and what mistakes beginners most often make.

If your refrigerator suddenly stopped freezing, but the light inside is on and the motor does not start, with an 80% probability it is the starter motor that is to blame relay Unlike service centers, where they will charge from 2,500 rubles for a replacement, you can do it for free, spending only 30–60 minutes of time. The main thing is to follow the instructions and not skip important details.

Signs of a faulty start relay

Before you start replacing, you need to make sure that the problem is in the relay and not in other components of the refrigerator. Here are the key symptoms:

• 🔴 The refrigerator does not turn on, but the light inside is on - this means that power is supplied, but the compressor does not start.
• 🔄 The compressor tries to start, but immediately turns off with a characteristic click (the cycle is repeated every 5-10 seconds).
• ⚡ The refrigerator works, but periodically “knocks out” the machine in the panel - this is a sign of a short circuit in the relay windings.
• ❄️ The motor hums, but does not gain momentum, and it is not cold enough in the chambers - perhaps the relay does not turn off the starting winding.

If at least one is observed Of these signs, with a 90% probability the relay is to blame. However, for an accurate diagnosis you will need ring the part with a multimeter. More on this in the next section.

It is important to distinguish a relay malfunction from a breakdown thermostat or compressor. For example, if the refrigerator does not respond when you turn the thermostat knob, the problem may be with it. And if the engine hums, but does not start, and the relay is intact, the compressor may be jammed.

How to check the starting relay with a multimeter

For diagnostics you will need a multimeter (even the cheapest model will do) and a screwdriver. Follow this algorithm:

1. Unplug the refrigerator and move it away from the wall to gain access to the compressor.
2. Remove the relay protective cover (usually it is secured with latches or one screw).
3. Disconnect the relay terminals from the compressor. Remember or take a photo of their location!
4. Switch the multimeter to resistance test mode (200 Ohm) and ring the relay contacts:
   • 🔌 Between the terminals S (start) and M (common) there should be resistance be 15–40 Ohm (starting winding).
   • 🔌 Between R (working) and M — 10–30 Ohm (working winding).
   • 🔌 Between S and R the resistance should tend to infinity (open).

If the readings differ from the norm (for example, an open or short circuit), the relay is faulty and requires replacement. Also inspect the part visually: melted contacts, cracks on the body or a burning smell are sure signs of breakdown.

⚠️ Attention: Do not touch the relay contacts if the refrigerator is connected to the network! Even when turned off, dangerous voltage may remain on some models.

Selecting a new starting relay for Atlant

Relay for refrigerators Atlant differ in compressor type and power. Here are the key parameters that you need to pay attention to:

The most popular relay models for Atlant:

• 🔹 DHR-1M —universal relay for compressors Danfoss power up to 140 W.
• 🔹 RTK-X-1 —suitable for most models with compressors Secop.
• 🔹 LSR-12 —a modern relay with overheating protection, compatible with new refrigerators.

When purchasing, be sure to check the model of your compressor (it is indicated on the sticker on its body). If you are not sure about the choice, take the old relay with you to the store - the seller will help you choose an analogue.

⚠️ Attention: Cheap Chinese relays without markings often do not correspond to the declared parameters. It is better to overpay 200–300 rubles for a certified part than to risk compressor breakdown.

Step-by-step instructions for replacing the relay

Now let's move on to the replacement process itself. You will need:

• 🔧 Phillips and flathead screwdrivers.
• 📸 Telephone for photographing the connection diagram.
• 🧤 Rubber gloves (optional).
• 🔌 New starter relay.

Step 1. Disconnection and disassembly

Unplug the refrigerator and carefully move it away from the wall. Remove the lower back cover (it is secured with 2–4 screws). Underneath it you will see a compressor with a relay attached to it. It is usually secured to the motor housing using a spring clip or screw.

Step 2. Dismantling the old relay

Take a photo of the location of the terminals (usually there are three of them: S, M, R). Carefully remove the wires, remembering which one went where. Unscrew the mounting screw (if any) and remove the relay from the compressor. Inspect the contacts on the compressor - if they are oxidized, clean them with fine sandpaper.

Step 3. Installing a new relay

Place the new relay on the compressor so that the terminals align with the old holes. Secure it with a screw or latch. Connect the wires according to your photo. Make sure that the contacts are tight and not loose.

Step 4. Checking operation

Plug in the refrigerator. If everything is done correctly, the compressor should start without clicks or extraneous sounds. Let the refrigerator run for 10-15 minutes to make sure it is stable.

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

If the compressor does not start, check:

1) The terminals are connected correctly (S and R may be reversed).

2) Integrity of the wires (sometimes they rub against the body).

3) Operability of the thermostat (close its contacts - if the motor starts, the problem is there).

If nothing helps, the compressor itself may be faulty.

Common mistakes when replacing relays

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here's what you shouldn't do:

• ❌ Ignore the terminal markings. If you mix up S and Rthe compressor will not start or will burn out.
• ❌ Use a relay from a different model. Even if it looks similar, the parameters current may not match.
• ❌ Do not clean oxidized contacts. Bad contact leads to overheating and repeated failure.
• ❌ Turn on the refrigerator without the back cover. This interferes with air circulation and can cause overheating compressor.

Another common mistake is attempting to repair a burnt-out relay. Some “masters” try to re-solder the contacts or clean up the burnt tracks, but this gives a temporary effect. The relay is a consumable, and if it breaks, you only need to change it.

If after replacing the relay the refrigerator works, but after a while it turns off again, check:

• 🔋 Mains voltage (should be 220–230 B).
• 🌡️ Room temperature (if above 30°C, the compressor may overheat).
• 🔧 Condition of the door seal (a worn rubber seal leads to overload of the motor).

Where to buy a relay and how much is it? costs

A new starting relay for Atlant can be purchased in the following places:

When buying online, pay attention to the reviews and ratings of the seller. Original relays are usually packaged in a branded box with a hologram. If the seller cannot provide a photo of the real product (and not a catalogue), it is better to refuse the purchase.

⚠️ Attention: AliExpress often sells relays labeled “For ATLANT”, but in fact these are universal Chinese parts of dubious quality. Look for sellers with a rating above 98% and the number of orders from 100+.

When is the best time to call technicians

Although replacing a relay is a relatively simple procedure, in some cases it is better to trust a professional:

• 🔧 If after replacing the relay the compressor does not start and you cannot find the reason.
• ⚡ If, when you turn on the refrigerator, the machine in the panel is triggered (possibly a short circuit in motor windings).
• 🔥 If traces of melting are visible on the compressor or relay, this may indicate serious electrical problems.
• 🛠️ If you are not confident in your skills in working with electrical appliances.

Cost of calling a technician in Moscow and regions:

• 📍 Diagnostics: 500–1,000 rubles.
• 🔧 Relay replacement: 1,500–2,500 rubles (excluding the cost of the part).
• 🔄 Comprehensive repair (if the problem is not only relay): from 3,000 rubles.

If you decide to call a technician, check by phone:

• 📋 Does he have original spare parts for Atlant.
• 🕒 How long will the repair take (in most cases - 30–60 minutes).
• 💰 Is there a guarantee for work and parts (standard - 6–12 months).

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

Is it possible to replace the relay without disconnecting the refrigerator from the network?

No! This is extremely dangerous. Even when switched off, voltage may remain on the compressor contacts. Always remove the plug from the socket before starting work.

How to distinguish the start relay from the thermostat?

The start relay is located directly on the compressor (usually at the bottom back of the refrigerator) and has 3 terminals. The thermostat is located inside the chamber (behind the plastic panel) and is connected to the temperature control knob.

How long does the starting relay last?

The average service life is 5–10 years. The duration of operation is affected by power surges, compressor overheating and the quality of the part itself. In new models Atlant relays with overload protection are often installed, which last longer.

Is it possible to use relays from another refrigerator (for example, Indesit or Biryusa)?

It is possible, but only if their technical parameters (current, resistance windings) are completely identical. For example, a relay from Indesit with a compressor Danfoss is suitable for Atlant with the same motor. But it’s better to take the original.

What to do if the new relay burns out immediately?

This is a sign of problems with the compressor (turn-to-turn short circuit) or voltage surges. Do not install the following relay until you check:

1. Resistance of the compressor windings (should be 10-40 ohms).
2. Voltage in the socket (should be 220-230 V).
3. Wiring condition (are there melts or short circuits).

If the compressor is faulty, it will have to be replaced.
