The sudden stop of the compressor and the silence that replaces the usual hum of a working unit always takes you by surprise. In most cases, the cause of the breakdown is the failure of the starting relay, which is responsible for starting the engine. Finding this small but critical part can turn into a real quest if you don’t know where exactly to look and what to look for when choosing.
The modern market offers many options: from original spare parts to universal analogues available at various retail outlets. Start relay is a device that supplies current to the motor winding at the moment it is turned on and turns it off when it reaches operating speed. A mistake when purchasing can lead to repeated breakdown or even combustion of the compressor, so you need to approach the choice of supplier responsibly.
In this article we will analyze the main sales channels, help you determine the compatibility of the part with your refrigerator model and tell you how to distinguish a quality product from a counterfeit one. Indesit, Atlant, Bosch or Liebherr —the principles of searching for spare parts for all brands are similar, but have their own nuances in labeling.
Do not delay repairs for a long time, since frequent attempts to start a faulty unit can damage the windings of the electric motor. A correctly selected part will ensure stable operation of the equipment for many years.
Official service centers and authorized stores
The most reliable, although not always the cheapest, way to purchase spare parts is to contact the official service centers of the brand. Here you are guaranteed to receive original start relaywhich fully complies with the manufacturer's specifications. Managers will select the part based on the serial number of your refrigerator, which eliminates the risk of error.
However, this method has its drawbacks. The waiting period for delivery of a rare part can range from several days to several weeks, especially if the refrigerator model has already been discontinued or belongs to the premium segment. In addition, the price at official points often includes a markup for the brand and a guarantee of compatibility.
⚠️ Attention: When ordering from a service center, be sure to ask for a receipt and a warranty card for the spare part. Original parts often have unique markings and the manufacturer's logo on the case, which cheap analogues do not have.
For owners of equipment from brands such as Siemens or Electrolux, this option may be the only way to find specific electronic launch modules that do not have direct universal analogues on the market.
How to find the official one service?
Enter the request “official service [brand] [your city]” into a search engine and check the address on the manufacturer’s website. Beware of scammers using similar names.
Specialized online stores of spare parts
The most popular solution for craftsmen and home craftsmen are specialized online stores selling components for household appliances. The range of such sites is huge: here you can find both rare originals and high-quality substitutes from trusted Chinese or European manufacturers.
The main advantage of such stores is the availability of detailed catalogs with photographs, diagrams and technical specifications. You can visually compare your old relay with the new one by noting the contact placement and housing shape. Many sites offer a selection function based on the refrigerator model, which greatly simplifies the task.
When choosing a store, pay attention to the following criteria:
- 📸 Availability of real photographs of the product from different angles, including the view of the contact group.
- 📝 Detailed description of technical parameters: voltage, type of contacts, operating current.
- 🚚 Delivery conditions and the possibility of return if the part does not fit.
- ⭐ Reviews from other customers, especially those who installed relays on similar models.
Often in such stores you can find universal relays suitable for a number of models. For example, one relay may be compatible with refrigerators Atlant, Nord and Biryusa. However, before purchasing a universal analogue, it is better to consult with a store technician.
Electronics and radio components markets
For those who prefer to “touch” a product before purchasing, large electronics markets and pavilions with radio components remain an excellent option. Here you can find departments specializing in components for household appliances. This is a good way to buy a starting relay if you need it urgently, “here and now.”
Market sellers often have deep practical knowledge and can visually determine the type of relay you have. They may offer several options to choose from, including used parts from disassembly or new universal models. The price here is usually lower than in official services, but higher than when ordering from China.
However, when buying on the market you need to be extremely careful:
- 🧐 Carefully check the integrity of the case: the absence of chips and cracks is critical for tightness.
- 🔌 Inspect the contacts for the presence of oxides or traces of soot, even if the part is new.
- 🗣️ Ask about the origin of the product: often refurbished parts are sold under the guise of new ones.
Do not forget that markets rarely provide an official guarantee. Therefore, the performance check (if possible) or visual inspection should be as thorough as possible. For complex electronic start relays, this option is less preferable than for simple induction ones.
Advertisement sites and sales boards
Advertisement boards, such as Avito or local analogues, represent a huge warehouse of used and new spare parts from individuals and small entrepreneurs. Here you can find rare relays for old models of refrigerators that have long been discontinued.
Private traders often sell parts from broken or burnt refrigerators. This could be a great chance to find an original for pennies. However, the risk of running into a faulty or worn-out part is maximum here. Starting device is a mechanical element, the resource of which is limited by the number of switching cycles.
⚠️ Attention: When buying a used relay, you act at your own peril and risk. The bimetallic plate inside could be “tired” and not provide the required operating current, which will lead to rapid failure of the compressor.
If you decide to use this option, be sure to agree on the possibility of inspection or return. Ask the seller why the donor refrigerator was disassembled. If the compressor burns out, there is no point in taking the relay from it - it could be the cause of the breakdown.
Chinese sites and marketplaces
E-commerce giants offer a wide range of spare parts at minimal prices. By ordering relays directly from China, you can save up to 50-70% of the cost. However, this option is suitable only for those who are not in a hurry, since delivery can take from two weeks to a month.
The main difficulty when ordering online is the exact determination of the model. Chinese sellers often use general photographs and rough descriptions. An error in one marking symbol can lead to the fact that you receive a part that will not physically fit into place or will not fit the electrical parameters.
When ordering, pay attention to:
- 📏 The exact dimensions and pin layout.
- ⚡ Indication of the coil voltage (usually 220V, but there are exceptions).
- 📦 Availability of a tracking number to track the parcel.
For popular models of refrigerators, such as Samsung or LG, complete repair kits, including not only a relay, but also a thermal relay (tablet) and even a capacitor. This can be more profitable and convenient than buying each part separately.
How to determine the model and compatibility of the relay
Before looking for where to buy a starting relay for a refrigerator, you need to accurately identify the required part. The marking is usually applied to the side or top edge of the plastic case. You need to look for codes starting with the letters R, RT, PTC or digital designations.
There are two main types of starting relays: induction (with a coil) and posistor (PTC). They are not interchangeable. Induction relays have a movable core and operate on the principle of an electromagnet, while posistor relays use the property of a semiconductor to change resistance when heated.
Below is a table of correspondence between popular markings and compatible brands:
| Relay marking | Type | Compatible brands | Features |
|---|---|---|---|
| RTK-1, RTK-1-3 | Induction | Atlant, Nord, Biryusa | Classical circuit, vertical mounting |
| LS-07B, LS-08B | Posistor (PTC) | Indesit, Ariston, Candy | Requires precise selection of resistance |
| 113L0101 | Universal | Danfoss, Secop | Often comes complete with a capacitor |
| 380EL | Posistor | Samsung, LG | Specific housing shape |
It is also important to take into account the power of the compressor. A relay designed for a low-power engine will burn out when trying to start a powerful unit. The permissible power in watts (for example, 1/4 HP, 1/3 HP) or current strength is often indicated on the case.
☑️ Check before purchase
Frequently asked questions (FAQ)
Is it possible to install a relay with a different marking if it is physically is it suitable?
Doing this is highly not recommended. Even if the seats and number of contacts match, the internal characteristics (cut-off current, response time) may differ. This will lead to the compressor not working properly, overheating or humming.
Is it worth buying a universal starting relay?
Universal relays (often come with three wires) are a temporary solution. They do not provide the same protection or trigger accuracy as the original models. They should be used only if it is impossible to find the original part or as a temporary measure.
Why does a new relay burn out immediately after installation?
There may be several reasons: the model was incorrectly selected (wrong operating current), the compressor is jammed (turn-to-turn short circuit), or the thermal protection relay is faulty. Before replacing, be sure to check the resistance of the motor windings.
Where can you find the marking if it is erased on the old relay?
If the marking is not readable, look for the model number of the refrigerator itself (on the sticker inside the chamber or on the back) and use spare parts catalogs or contact a specialist who will select an analogue based on your electrical circuit model.
Is it difficult to replace the relay yourself?
Replacing a mechanical relay is simple: you need to remove the back cover, disconnect the wires, remove the old one and install a new one. However, working with electricity requires compliance with safety precautions. Be sure to disconnect the refrigerator from the mains before starting work!
