Sudden stoppage of the compressor or characteristic clicks, after which the refrigerator Beko stops freezing, often indicate a malfunction of the starter protection device. This is a small but critical part responsible for starting the engine and protecting it from overloads. When this part fails, the compressor either does not start at all or operates jerkily, which can lead to spoilage of products and more serious repairs to the unit.
It is important for owners of household appliances to understand that starting relay is a consumable item that wears out over time. In refrigerator models Beko it is usually located in close proximity to the compressor, however, the exact location and method of attachment may vary depending on the specific series and year of manufacture of the device. Correctly identifying the location of the element is the first step to successfully restoring the functionality of the equipment.
Independent diagnosis and replacement requires caution, since you will be working with electrical components. In this article, we will analyze in detail the relay search algorithm, consider the design features of various models Beko and provide a step-by-step action plan. In most cases, replacing a relay takes no more than 20 minutes and does not require a specialized tool other than a screwdriver.
Design and purpose of the starting relay in the Beko system
The starting relay in refrigerators Beko performs the function of an automatic switch. When the unit is turned on, a current passes through the stator winding, which creates a magnetic field that draws in the core and closes the contacts of the starting winding. As soon as the engine reaches the required speed, the current drops and the relay opens the starting winding circuit, allowing the motor to operate normally on the main winding.
In addition to the starting function, the device is often combined with a thermal protective element. If the compressor overheats or draws too much current (for example, when it seizes), the bimetallic strip inside the relay opens the circuit, preventing the motor from burning out. Thermal relay is a key safety element, ignoring problems with which can lead to costly replacement of the compressor.
Modern models Beko can use relays of different types: posistor or induction. PTC variants are more common in new series; they are more compact and reliable. Induction ones are found in older models. Understanding the type of your device will help you quickly find an analogue for replacement.
⚠️ Attention: If after replacing the relay the compressor hums but does not start, and after a few seconds the click is heard again, immediately unplug the refrigerator. This may indicate a malfunction of the compressor itself or an interturn short circuit, and further attempts to start may permanently damage the unit.
Visually, the relay is a small plastic or black hard rubber box placed on three pins of the compressor. The body of the part is usually marked with technical specifications such as voltage and type of compatible compressors. It is based on these parameters that a new part is selected.
The exact location of the relay in various models of refrigerators
The question “where is the relay located” has one main answer: on the compressor housing. However, access to this unit in refrigerators Beko is organized differently. In classic two-chamber models, the compressor is traditionally located at the lower rear of the unit. To get to it, you need to move the refrigerator away from the wall and remove the back metal cover secured with screws.
In models like Beko No Frost or built-in series, the layout may be denser. Here the relay is often hidden behind additional plastic casings or protective screens that are secured with latches. Sometimes for access it is necessary to remove not only the back panel, but also dismantle the ventilation grill covering the condenser.
It is worth noting that in some modern modifications Beko with inverter compressors, the classic starting relay may not be in its usual form. Inverter systems are controlled by an electronic unit, and starting currents are regulated differently there. Therefore, if you do not find the characteristic “barrel” on the compressor, perhaps your equipment is of the inverter type.
When searching, focus on the massive black cylinder (the compressor itself) at the bottom of the rear wall. The relay is always placed directly on its contact group. If there is nothing similar at the back, check the instructions for your model, since in rare cases (for example, in some compact models) the compressor may be placed in a separate compartment or have a non-standard location.
Instructions for safe access and dismantling of the part
Before starting any work to find and remove the relay, you must completely de-energize the refrigerator. Unplug the power cord from the outlet. This is a critical safety rule as you will be working near live parts and a capacitor that may retain residual charge.
Once unplugged, carefully move the unit away from the wall to allow easy access to the rear panel. Using a Phillips screwdriver, remove all screws holding the metal casing in place. In some models Beko the screws may be hidden under decorative plugs or rubber feet, so inspect the panel carefully.
☑️ Preparing to dismantle the relay
When access is open, you will see the compressor. The relay is placed on its contact block on the side. Before removal, it is strongly recommended to take photographs of the location of the wires and the color of the terminals. This will help avoid mistakes when installing a new part, since reverse polarity can burn the new component.
Removal usually does not require a tool. The relay is held in place by a tight fit and is sometimes secured with a metal bracket or plastic latches. If there is a bracket, carefully pry it off with a flathead screwdriver. If the relay is simply put on the pins, grab it with your hands and, slightly rocking it from side to side, pull it down. Do not use excessive force to avoid damaging the compressor contacts.
Fault diagnosis and signs of breakdown
You can understand that the relay has failed by a number of indirect signs. The most obvious is that the refrigerator Beko does not turn on, only the power indicator is on, but the compressor is silent. Or you hear a loud click, followed by a hum that lasts a few seconds, and again the click is an attempt to start, which the relay cannot complete.
Another sign is that the compressor is overheating. If the motor runs continuously without turning off, and the body of the unit is very hot, the relay contacts may be stuck and it does not open the starting winding. In this case, the engine operates in extreme mode, which is fraught with combustion.
Visual inspection of the removed part also provides a lot of information. Shake the relay next to your ear: if something dangles and rings inside, it means the ceramic posistor or core has fallen apart. Also pay attention to the presence of carbon deposits, plastic melting or a characteristic burning smell - these are sure signs of electrical breakdown.
Is it possible to check the relay with a multimeter?
Yes, if you have a multimeter, you can ring the contacts. Under normal conditions, the resistance between certain contacts should be close to zero (closed) or infinity (open) depending on the relay type and temperature. A posistor in a cold state has a low resistance, which increases sharply when heated. However, the most reliable way to check is to install a known-good analogue.
Often users confuse a relay malfunction with a broken thermostat or starting capacitor. If the relay is visually intact and shows normal when tested, but the refrigerator does not start, the problem may be deeper. In such cases, it is better to contact a professional technician to diagnose the compressor.
Selection criteria and parts compatibility table
When purchasing a new relay for Beko Knowing just the model of the refrigerator is not enough. Factories may use compressors from different manufacturers (for example Secop, Danfoss, Embraco) in the same refrigerator model. Therefore, the key parameter is the marking on the oldest relay or on the compressor nameplate.
Pay attention to the type of refrigerant (R600a or R134a), since the pressure in the system and the starting torque requirements depend on this. Also important is the compressor power, indicated in watts or LBP (Low Back Pressure) class. An incorrectly selected relay will operate unstably.
| Parameter | Description and importance | Where to look |
|---|---|---|
| Relay model | Unique manufacturer code (for example, 160R, 180R, PTC-Relay) | On the side of the old relay |
| Compressor type | Low pressure (LBP) - standard for refrigerators | On the compressor nameplate |
| Refrigerant | Gas type (R600a or R134a), affects the load | On the nameplate on the back of the refrigerator |
| Orientation | Vertical or horizontal installation of contacts | Visually on an old relay |
If you cannot find an exact analogue by catalog number, you can select a universal starting relay. They are sold with a set of adapters for different types of contacts. However, for long-term and reliable operation Beko it is better to look for original spare parts or high-quality analogues from well-known brands, such as Danfoss or Secop.
Installing a new relay and checking its functionality
The installation process is performed in reverse order. First, make sure that the new relay has cooled down (if you experimented with heating) and has no visible defects. Carefully slide it onto the contact pins of the compressor. It should fit tightly, without play, but do not require the use of a hammer or excessive force.
Connect the wires to the relay terminals. This is where a photo taken before dismantling will come in handy. Typically the wires are color coded or have terminal markings (S, R, C). Make sure that the connections are secure and do not loosen, as the vibration of a running compressor may disrupt the contact.
After assembly, do not rush to close the back cover. Plug in the refrigerator and listen. There should be one click followed by a steady hum from the compressor. After a few seconds, the hum may change slightly (the starting winding will turn off) - this is normal. If you hear a series of frequent clicks or an intermittent hum, turn off the equipment immediately.
⚠️ Attention: Technical characteristics of compressors and relay types may vary depending on the year of production. Before purchasing, check the markings on your specific part with supplier catalogs, since visual similarity does not guarantee compatibility of electrical parameters.
If the start-up was successful, let the refrigerator run for about 15-20 minutes without the back cover (to control the temperature), then replace the cover and secure it with screws. Make sure that all wires are removed and do not touch hot parts of the compressor or moving fan elements.
Frequently asked questions (FAQ)
Is it possible to repair the old relay, or just replace it?
Repairing the starting relay, especially posistor, is practically impossible and economically unfeasible. A posistor is a ceramic element that is destroyed upon breakdown. In induction relays, the coil often burns out or the contacts stick. The cost of a new part is low, so replacement is the only reasonable solution.
Why does a new relay burn out a short time after installation?
If a new relay Beko fails quickly, this indicates a more serious problem. Most often, the reason is a malfunction of the compressor itself (interturn short circuit, jamming of the piston group), which consumes increased current. Also, the cause may be unstable voltage in the network or a faulty wiring of the refrigerator.
What is the difference between the relay for R600a and R134a?
The difference lies in the characteristics of the starting torque. Isobutane (R600a) compressors usually require more precise starting control due to the nature of the gas and motor design. Using a relay that is not designed for a specific type of refrigerant may result in the compressor either not starting or operating under overload.
How long does a start relay last in a refrigerator?
The average service life of a quality relay is 5-10 years. However, this resource can be significantly reduced by frequent voltage fluctuations in the electrical network, unstable room temperature or frequent on-off cycles (for example, if you often open the refrigerator door).
Where to buy an original relay for Beko?
It is best to look for original spare parts in authorized service centers Beko or specialized stores of spare parts for household appliances. When ordering online, be sure to indicate the full model number of the refrigerator and, if possible, the code of the old relay. In electronics markets, universal analogues are often sold that are suitable in size, but may differ in electrical parameters.
