How to remove the relay from a two-chamber refrigerator yourself Atlant: instructions with photos and tips

Two-chamber refrigerators Atlant are known for their reliability, but even they are not immune from breakdowns. One of the common malfunctions is the failure of start relay, which is responsible for starting the compressor. If your unit suddenly stops freezing, makes clicking noises, or does not turn on at all, the problem may lie in this particular unit. You can remove the relay from the refrigerator Atlant on your own, without resorting to the services of a specialist - the main thing is to act carefully and follow the proven instructions.

In this article we will look at how to properly dismantle relay on models Atlant with two cameras (for example, MHM 1705-80, MHM 2835-08 and similar), what tools will be needed, and what to pay attention to so as not to damage other parts. You will also learn how to check the relay for functionality and what to do if after replacing the refrigerator still does not work.

Why remove the relay from the refrigerator and when to do it necessary

Start relay is a small device that is attached to the compressor and ensures its start. It protects the motor from overheating and short circuits. Over time, the relay contacts may burn out, the springs may lose their elasticity, and the bimetallic plate may deform. All this leads to malfunctions of the refrigerator.

Signs of a relay malfunction in which it should be removed and checked:

• 🔊 The compressor does not start, but clicks are heard (the relay tries to work, but to no avail).
• ❄️ The refrigerator does not freeze, although the light inside is on.
• ⚡ The device turns on for a few seconds and immediately turns off.
• 🔥 There is a smell of burning or melted plastic near the compressor.

If you observe at least one Of these symptoms, the first thing to check is the relay. In 60% of cases, replacing or cleaning it solves the problem. But before removing the part, make sure that the refrigerator plug is tightly inserted into the socket, and the voltage in the network is stable - sometimes the cause of an “imaginary” breakdown is a banal lack of power.

Preparation for dismantling: tools and safety measures

Before starting work, prepare everything you need. You will need:

• ⚒️ Phillips and flathead screwdrivers (size depends on the model, usually PH2 or SL 3.5 mm).
• 🔧 Wrench on 8 mm or 10 mm (for fastening the compressor, if required).
• 📸 Phone or camera (to photograph the location of the wires before disconnecting).
• 🧤 Dielectric gloves (to protect against possible electric shock).
• 🔦 Flashlight (lighting at the back of the refrigerator often leaves much to be desired).

Important: Before starting work be sure to disconnect the refrigerator from the networkIt is not enough to just pull out the plug - if your model has a capacitor, it can save. charge. To discharge it, close the contacts of the capacitor with a screwdriver with an insulated handle (holding only the handle!).

Also prepare the work space:

• 🪑 Clear access to the back wall of the refrigerator (move it 50–60 cm from the wall).
• 🧹 Remove dust from the compressor and relay with a dry cloth - this will help prevent dirt from getting inside after dismantling.
• 📝 Write down or photograph the location of the wires so that you can connect them correctly later.

⚠️ Attention: If your refrigerator Atlant is under warranty, independent repairs may void the warranty.

Where is the relay in the Atlant refrigerator and how to identify it

In two-chamber refrigerators Atlant the relay is located on the compressor, which is located in the lower part of the back wall. The compressor looks like a black metal one. a cylinder with tubes, and a relay - like a small plastic box (usually black or gray) attached to its side.

Depending on the model, the relay can be:

• 🔄 Start protection relay (combines start and protection functions, the most common option).
• 🔌 Start relay (separately) + thermal relay (for protection against overheating).

On Most refrigerators Atlant use a relay type RTK-X or RTP-1. To accurately identify the part, look at the marking - it is printed on the relay body. For example, the inscription RTK-X 1/10 means that the relay is designed for current. 1 A and compressor power up to 10 kW.

If you are not sure which relay is installed in your model, check the technical data sheet of the refrigerator or find information by the model number (it is indicated on the sticker inside the chamber or on the back wall). data-i="125">Atlant MKhM 1840-80 Atlant MHM 1840-80 suitable relay RTK-X 1/10, and for Atlant MKhM 2835-08 — RTP-1.

How to find the model number refrigerator?

The model number is indicated on the nameplate, which is located on the inner wall of the refrigerator compartment (usually on the left) or on the rear wall outside. The sticker contains information about the serial number, production date and technical characteristics.

Step-by-step instructions: how to remove the relay from the Atlant refrigerator

Now Let's move on to the process itself. Follow the instructions step by step to avoid mistakes:

1. Disconnect the refrigerator from the mains and discharge the capacitor (as described above).
2. Remove it. protective cover of the compressor (if it has one).
3. Take a photo of the location of the wiresfitting to the relay. This will help not to confuse them during reassembly.
4. Disconnect the wires from the relay terminals. To do this, carefully pull them up or to the side (depending on the type of connector, they will have to be soldered). unsolder.
5. Unscrew the mounting screwsthat secure the relay to the compressor. Usually these are 1-2 screws with a Phillips screwdriver.
6. Remove the relayby pulling it towards you. "stuck", do not use excessive force - try to carefully pry it off with a flat screwdriver.

On some models Atlant the relay may be mounted on a special bracket. In this case, first remove the bracket and then dismantle it itself. relay.

If you plan to replace the relay, take the old one with you to the store - this will help you choose identical model. If you want to repair it, inspect the contacts for burning. Often it is enough to clean them with fine sandpaper (zero) for the relay to work again.

⚠️ Attention: Some relays (for example, RTP-1) contain spring mechanisms. When dismantling, they may jump out - hold the part above the table or place your hand so as not to lose the parts.

How to check the removed relay for functionality

Before buying a new relay, make sure that the old one is really faulty. To check you will need multimeter (tester). Follow this algorithm:

1. Ring the relay coil:
   • Set the multimeter in resistance measurement mode (200 Ohm).
   • Connect the probes to coil contacts (usually terminals 1 and 2 on the relay body).
   • The resistance should be within the limits 20–50 OhmIf the device shows 0 (short circuit) or ∞ (break), the relay is faulty.

Check the contacts:

• Switch the multimeter to the mode continuity (diode icon).
• Connect the probes to the power contacts of the relay (usually 3 i 4).
• When the contacts are closed (you can simulate it manually), a sound signal should sound. If not, the contacts are burnt or oxidized.

Also inspect the relay visually:

• 🔥 Burnt or melted areas on the body.
• 💥 Cracks in the plastic.
• 🧲 Deformation of the bimetallic plate (if visible).

If the relay fails at least one of the tests, it must be replaced. Relays from other brands (for example, Indesit or Samsung) cannot be installed in Atlant refrigerators - even if they are similar in appearance. This can lead to compressor failure.

Symptom	Probable Cause	Solution
The relay does not “click” when power is applied	Broken coil or faulty bimetallic plate	Replacing the relay
There are clicks, but the compressor does not start	The contacts are burnt or the compressor is faulty	Cleaning the contacts or replacing the relay/compressor
The relay gets very hot	Interturn short circuit in the coil	Replacing the relay
The relay body is melted	Short circuit or overload	Replacing the relay + checking the compressor

Installing a new one relay and checking the functionality of the refrigerator

If you are convinced that the relay is faulty, install a new one. To do this:

1. Attach the relay to the compressor in the same position as the old one (use the photo taken earlier).
2. Tighten the fastening screws, but do not overtighten - plastic. may crack.
3. Connect the wires to the relay terminals in accordance with the diagram. Usually the wires are marked:
   • 🔴 Red or brown - phase (L).
   • 🔵 Blue - zero (N).
   • ⚫ Black or yellow - compressor starting winding.

Replace the compressor protective cover (if there was one).

Connect the refrigerator to the network and check its operation.

After installing the new relay:

• 🕒 Let the refrigerator operate for 1-2 hours as usual.
• 🌡️ Check whether the temperature in the chambers is rising (should drop to +4...+6°C in the refrigeration and -18°C in the freezer).
• 🔊 Listen to the sounds: the compressor should start without clicks or extraneous noise.

If the refrigerator still does not work, the problem may be in the compressor, thermostat or electrical circuit. In this case, it is better to contact a specialist.

Common mistakes when removing and replacing relays

Even experienced technicians sometimes make mistakes that lead to new breakdowns. Do not do When working with a relay:

• ⚡ Ignore the discharge of the capacitor. Residual charge can damage the multimeter or cause electric shock.
• 🔧 Use unsuitable screwdrivers. A screwdriver that is too large or small will tear off the slots on screws.
• 🔌 Confuse the wires when connecting. If you confuse phase and zero, the relay will burn out immediately after switching on.
• 💦 Work in wet conditions. Moisture can cause a short circuit.
• 🔨 Use excessive force. The plastic case of the relay is fragile - it is easy to break.

Another common mistake is buying a relay "by eye". Even if it looks like the original, the technical parameters (current, power) may not be correct. match. Always check the markings on the old relay or the technical documentation of the refrigerator.

⚠️ Attention: If after replacing the relay the refrigerator turns on, but after a few seconds it turns off, check starting capacitor. It may be faulty and block the operation of the compressor.

FAQ: Answers to frequently asked questions about the Atlant refrigerator relay

Can the relay be repaired or just replaced?

In most cases, the relay can only be replaced, especially if the coil or bimetallic plate is faulty. However, if the problem is only burnt contacts, they can be cleaned with fine sandpaper. Before installing it back, check the relay with a multimeter.

How much does a new relay cost for Atlant?

The price depends on the relay model and region. On average, a start-up relay for refrigerators Atlant costs. from 500 to 1500 rubles. Original parts (for example, RTK-X) are more expensive than analogues, but last longer.

What to do if, after replacing the relay, the compressor hums but does not start?

This may indicate:

• Compressor malfunction (interturn short circuit or jamming).
• Problems with the starting capacitor.
• Incorrect connection of the wires to the relay.

Check the resistance of the compressor windings with a multimeter. If it differs from the norm (indicated in the refrigerator's passport), the compressor will have to be replaced.

How often should the relay be checked?

The relay does not require regular maintenance, but it is worth checking at the first signs of a malfunction (clicks, failure to start). If the refrigerator operates stably, it is enough to inspect the relay once every 2-3 years during general cleaning.

Can I use a relay from another refrigerator?

Only if it is completely identical in technical parameters (current, power, type). data-i="265">may be suitable for Atlant MHM 1705 may be suitable for Atlant MHM 1840if they have the same compressors. But a relay from Indesit or Stinol cannot be installed - this will lead to compressor failure.
