Where is the relay located on the Beko refrigerator: search and replacement

When your refrigerator Beko suddenly it stops freezing, and only rare clicks or buzzing are heard inside, which immediately subsides, the problem most often lies in the start-up relay. This small but critical element is responsible for starting the compressor, which is the “heart” of the entire cooling system. If the motor does not start, it means that the power circuit is not closed properly and the refrigerant is not circulating through the pipes.

For equipment owners Beko it is important to understand that the relay is not located in a random place inside the cabinet, as many newbies think. It is always located in close proximity to the compressor, which is usually hidden at the lower rear of the unit. You can get to this unit only by moving the refrigerator away from the wall and removing the protective back cover, if it is provided for by the design of a particular model.

In this article we will look in detail at what exactly the relay looks like, where it is mounted on different models Beko and how to determine that this particular component has failed. Start relay is a consumable a material that wears out over time and is often cheaper to replace than calling a professional. However, before starting work, you need to make sure that the procedure is safe and correctly identify the part.

The role of the start relay in the operation of the compressor

To understand why the relay often causes a breakdown, you need to consider its function. The moment the refrigerator is turned on, the compressor needs a powerful impulse to move the pistons and start pumping freon. Normal voltage is not enough for this, and this is where starting relaycomes into play. It briefly supplies increased voltage to the starting winding of the engine, after which it turns off, leaving only the main winding to work.

In devices Beko most often there are two types of such devices: posistor (solid-state) and induction (with a coil). PTC models are more modern, compact and have no moving mechanical parts, which makes them more reliable. Induction options, which can be recognized by the characteristic sound of a falling “puck” when shaking, are gradually becoming a thing of the past, but are still found in older models.

⚠️ Attention: If after the relay clicks, the compressor hums, but does not start, and after 10-20 seconds the click is heard again, immediately disconnect the device from the network. Long-term operation in this mode ("sticky start") can lead to burnout of the motor windings, and then repairs will cost a complete replacement of the compressor.

In addition to the start function, this element is often combined with thermal protection. Thermal relay opens the circuit if the temperature inside the motor becomes critical, preventing a fire or melting of the insulation. Therefore, even if the motor is working properly, but overheats due to poor ventilation or dirt, this particular unit will constantly de-energize the equipment.

The exact location of the part in the Beko design

Searching for a relay does not require deep knowledge of the anatomy of the refrigerator, since manufacturers have standardized the location of the units. For models Beko, like most brands, the compressor is mounted on the frame at the bottom of the rear wall. The relay is placed directly on the output contacts (plugs) of the compressor. You do not need to look for it at the top of the refrigerator compartment or inside the freezer.

To see the component, follow these steps:

• 🔌 Unplug the refrigerator from the electrical outlet by removing the plug from the outlet.
• ❄️ Move the unit away from the wall, allowing access to the back panels.
• 🔧 Remove the cardboard or metal cover covering the compressor compartment (if there is one).
• 👀 Find the black “barrel” - this is the compressor, and there will be a plastic box on its side or top.

Sometimes the relay is covered with an additional protective cover made of metal or plastic, which is fixed with a clamp or latches. In models Beko with the NoFrost system, access may be a little difficult with a fan or control unit, but the starting unit itself is always attached to the motor. Mounting it is carried out simply by a tight fit on the contacts, sometimes additionally secured with a metal bracket.

Symptoms of malfunction and diagnostics

Before buying a new part, you need to make sure that this is the problem. The symptoms of a starter failure are quite specific. Most often, the owner hears a characteristic click, after which the refrigerator is silent or hums quietly for several seconds, followed by a second click and silence. The cycle can be repeated every few minutes.

If you have a multimeter, diagnostics can be carried out more accurately. After removing the relay from the compressor contacts, you need to carefully open it (if it is not monolithic) or simply ring the contacts. In a working posistor, the resistance should be within normal limits (usually several tens of Ohms), and when heated, it should go to infinity. A mechanical relay should not make rattling sounds when shaking unless the core inside has broken off.

Visual inspection is also worth a lot. Pay attention to the condition of the plastic:

• 🔥 The presence of melting or blackening indicates overheating of the contacts.
• 💨 The smell of burning or scorched plastic is a sure sign of a short circuit inside.
• 🧱 Cracks in the case can allow moisture to pass through, causing oxidation.

If the relay visually looks intact, but the refrigerator does not turn on, the problem may be deeper. Perhaps the compressor itself is jammed or there is a break in the windings. In such cases, simply replacing the relay will not help, and the intervention of a professional with a manifold will be required to check the pressure in the system.

Compatibility table and relay types

The spare parts market for refrigerators Beko is huge, and it is easy to get confused in the markings. It is important to understand that the relay is selected not so much by the model of the refrigerator, but by the type and power of the compressor. Below is a table that helps you navigate the main types of devices found in this technology.

When ordering spare parts in an online store or service center, be sure to tell the manager the model of your compressor (indicated on the sticker on the “barrel”), and not just the model of the refrigerator. Compatibility is a key factor: an unsuitable relay may either not start the motor or burn out in the first seconds of operation.

Instructions for replacing the relay with your own by hand

If you have identified the fault and bought a suitable analogue, you can proceed with replacement. This process does not require complex tools, but it does require precision. The main rule is that all work is carried out only on a completely de-energized device.

Step-by-step algorithm of actions:

• 🛑 Make sure that the plug has been unplugged from the socket for at least 15-20 minutes.
• 🔩 Remove the back cover of the compressor compartment.
• 📸 Take a photo of connecting the wires so as not to confuse anything during assembly.
• 🔌 Carefully remove the old relay from the compressor contacts (sometimes you need to remove the fixing bracket).
• 🆕 Put the new relay on all the way, check the tightness landing.
• 🔙 Put the lid in place and turn on the refrigerator.

After turning on, listen to the operation of the unit. The engine should start smoothly, without strong jerks or loud clicks. If after 5-10 minutes of operation the compressor begins to noticeably cool, and heat appears on the rear grille of the condenser, the repair has been completed successfully. If the symptoms recur, perhaps the problem is not in the relay, or the new part is defective.

Typical errors during repair

Independent repair is always a risk, especially when it comes to live electrical appliances. One of the most common mistakes is an attempt to “reanimate” an old relay by tapping or cleaning the contacts with sandpaper. In the case of posistors, this is useless, since the crystal itself degrades, not the contacts.

Another mistake is ignoring the state of the wiring. Often it is not the relay itself that melts, but the wires that go to it due to poor contact. If you simply replace the relay but don't strip and repair the burnt wires, the new part will burn out within a week. Always check the quality electrical contact and, if necessary, use heat shrink for insulation.

⚠️ Attention: Never leave the relay hanging on the wires with the refrigerator turned on “for testing”. Vibration of a working compressor can lead to a short circuit to the housing or adjacent tubes, which is life-threatening.

Also, you should not use relays from other equipment (for example, from air conditioners or old Soviet refrigerators) without carefully checking the parameters. The starting current and rated power must be the same. Installing an unsuitable component may result in the protection not working at the right time, and the motor will burn out.

Prevention and service life

The service life of the starting relay in refrigerators Beko on average is 5-10 years, but it greatly depends on operating conditions. Frequent power surges in the network are the main enemy of electronics and starting equipment. Using a surge protector or voltage stabilizer can significantly extend the life of not only the relay, but also the entire compressor.

It is also important to monitor the cleanliness of the compressor compartment. Dust, animal hair and cobwebs that accumulate on the condenser grille and around the motor impair heat transfer. The compressor overheats, the thermal protection trips more often, and the relay life is reduced. Regular (once a year) cleaning the back of the refrigerator with a vacuum cleaner is an excellent preventive measure.

If you live in an area with unstable power supply, pay attention to the condition of the outlet. Sparking at the point of contact between the plug and the socket also negatively affects the inrush currents. In such cases, it is better to replace the socket with a high-quality one, with reliable contact clamping.

How much does it cost to replace a relay in a service compared to self-repair?

The cost of the part itself usually ranges from 500 to 1500 rubles, depending on the model. The work of an on-call technician will cost 1,500-2,500 rubles plus the cost of spare parts. Thus, self-replacement saves you an amount equal to the cost of the work itself, but requires time and minimal skills.

Can a relay stick and how to check it?

Yes, in mechanical relays sometimes the contacts or the moving core get stuck. You can check this by removing the relay and shaking it near your ear. If you hear a clear knocking sound of a “dangling” element, the part is faulty. It is useless to shake the posistor; it can only be checked with a multimeter.

Where to buy an original relay for Beko?

It is better to look for original spare parts in authorized service centers Beko or specialized stores of spare parts for household appliances. In markets and general construction hypermarkets, universal Chinese analogues are more often sold, which may work less stably.

Why does the new relay heat up during operation?

Slight heating of the relay body (up to 50-60 degrees) during operation is normal, especially for posistors, which operate by changing the resistance when heated. However, if the housing melts or there is a burning smell coming from it, this is a sign of a malfunction or incorrect selection.
