Sudden stoppage of the refrigerator Vestel often becomes unpleasant surprise, especially when food in the chamber begins to spoil. In most cases, the cause of the breakdown is the failure of the starting mechanism, which is responsible for starting the engine. Start relay - this is a small but critical component, without which the compressor cannot start operating or maintain it in normal mode. Understanding where exactly this element is located is the first step to successfully restoring the functionality of household appliances.
Turkish brand refrigeration equipment Vestel is famous for its reliability, but the life of electrical components is not endless. Often, owners are faced with a situation where the engine hums but does not start, or turns on for just a few seconds and turns off. These are classic symptoms of a malfunction in the starting circuit. The relay in Vestel models is almost always located directly on the compressor casing, in the lower rear part of the unit. Access to it requires dismantling the protective panel, but the procedure itself does not require complex special tools.
Before proceeding with disassembly, it is necessary completely disconnect the device. Working with live electrical components is strictly prohibited and is life-threatening. After disconnecting the cord from the retail outlet, you should move the refrigerator away from the wall to provide free access to its rear wall. It is there, in the lower part, that the core of the cooling system is hidden - the compressor unit.
The design and location of the compressor compartment
The rear wall of the refrigerator Vestel closes access to technical components that normally do not require user intervention. The compressor, which is the main engine of the system, is attached to the frame at the bottom of the housing. Above the metal motor tank there is a plastic or metal cover that protects the electrical contacts from dust, moisture and mechanical damage. It is under this cover that the required starting relay is hidden. Depending on the specific refrigerator model, the design of the protective casing may differ. In some modifications this is a single plastic box covering the upper part of the motor. In other cases, a metal plate secured with a clamp is used. Inside this space, on the three protruding contacts of the compressor, a block with a relay and a thermal protector is mounted. start relay.
Depending on the specific refrigerator model Vestel, the design of the protective casing may vary. In some modifications this is a single plastic box covering the upper part of the motor. In other cases, a metal plate secured with a clamp is used. Inside this space, on the three protruding contacts of the compressor, a block with a relay and a thermal protector is mounted. Thermal relay often combined with the starting unit into a single unit, which simplifies the design, but requires care when replacing.
⚠️ Attention: Plastic The compressor housing may be fragile, especially if the refrigerator has been in use for a long time. When removing the cover, avoid sharp jerks so as not to break the locking latches or the protection body itself.
To visually inspect the search area, it is not necessary to immediately disassemble the entire assembly. It is enough to remove the outer metal or plastic panel of the rear wall, which is usually attached to several screws around the perimeter. When you unscrew them, you will see a black cylindrical or pear-shaped compressor tank. A small box will be visible on the side or top of it - this is the installation location starter.
Instructions for accessing the relay and removing the protective cover
The process of gaining access to the insides of the compressor group requires accuracy and consistency of actions. The first step is to remove the back panel of the refrigerator Vestel. It can be whole or consist of several parts. Use a Phillips screwdriver to remove the mounting screws. After removing the panel, you will have a view of the motor and the tubes suitable for it.
The next step is to dismantle the protective casing above the compressor. If it is a plastic box, it may be held in place by latches or screws. Carefully press the latches or unscrew the fasteners. If using a metal clamp, loosen it and remove the cover. The electrical part of the motor will appear before you. Relay It is a black or white plastic parallelepiped put on the contacts.
☑️ Preparation for removing the relay
It is important not to confuse the relay with a capacitor, which may also be located in this area. The capacitor is usually cylindrical and mounted separately on a frame or wall, while the relay is mounted directly on the compressor rod. In models Vestel with inverter compressors, the design may be different, and an electronic control unit is used, but in the classic lines a mechanical or electronic-mechanical starting device is used.
Types of relays used in Vestel refrigerators
In refrigerators Vestel Depending on the year of manufacture and model of the compressor, different types of starting devices can be used. Understanding the differences helps you correctly identify the part and select a replacement. There are two main types: posistor (starting) and induction, although the former dominate in modern technology.
Posistor relays operate on the basis of a material that sharply changes its resistance when heated. When voltage is applied, the posistor is cold and passes current to the starting winding. After a few seconds it heats up, the resistance increases, and the circuit opens. Such devices are compact and reliable. Induction relays operate on the principle of an electromagnetic core, which is retracted when the inrush current occurs and opens the contacts. They are noisier and are found in older models.
- 🔌 Posistor relay —the most common option, has no moving mechanical parts inside, operates silently, but is sensitive to current overloads.
- 🧲 Inductive relay —contains a movable core and contacts, makes a characteristic click when activated, is more durable in conditions of unstable voltage, but cumbersome.
- ⚡ Combined unit — in some models Vestel the starting relay and thermal protection are combined in one housing, which requires replacing the entire unit if any element breaks down.
By visual inspection of the removed part, you can determine its type. PTC variants are often marked with resistance (for example, 15 Ohm, 22 Ohm). Induction can be recognized by the presence of a movable rod inside a transparent or collapsible body. Refrigerators Vestel are characterized by the use of universal relays, which are easy to find on sale by catalog number or compressor parameters.
Fault diagnosis: signs and testing
Before buying a new part, you should make sure that the problem lies in the relay. The symptoms of a malfunction of this unit are quite specific. If the refrigerator Vestel does not turn on, but the light in the chamber is on, and a hum is heard from the back, lasting 5-10 seconds, followed by a click and silence - this is a sure sign.
Another sign is a characteristic burning smell or melted plastic in the compressor area. This may indicate a short circuit inside the relay or overheating of the contacts. It is also worth paying attention to the condition of the compressor itself: if it is hot and no cold is generated, it means that attempts were made to start, but were unsuccessful. Thermal protection in this case it is triggered, turning off the motor to avoid burning out the windings.
The test can be performed with a multimeter in continuity mode. To do this, you need to remove the relay and check the circuits. In the normal state, the resistance between certain contacts should be close to zero, and in others it should correspond to the posistor rating (10-60 Ohms). If the device shows an open or short circuit where it should not be, the part is faulty.
| Symptom | Probable cause | Action |
|---|---|---|
| Humming for 5 seconds, clicking, silence | The relay contacts are jammed or the posistor is burned out | Replacing the start relay |
| The refrigerator does not turn on at all | Thermal protection or thermostat is faulty | Checking the circuits multimeter |
| Frequent on/off | Broken contact in the relay block | Cleaning contacts or replacing |
| Burning smell, black coating | Short circuit in the relay | Urgent replacement of the unit |
⚠️ Attention: If after replacement relay, the refrigerator stopped starting again after a short time, the problem may be in the compressor itself (turn-to-turn short circuit). In this case, simply replacing the relay will not help.
The process of replacing the starting relay with your own hands
Replacing the relay in the refrigerator Vestel is a procedure that is accessible even to a beginner, if you are careful. Once you have reached the compressor and removed the protective casing, you need to disconnect the wires. It is best to take a picture of the connection diagram first so as not to confuse the colors during assembly. Usually the wires are simply inserted into the relay terminals.
The relay itself is tightly placed on the compressor contacts. To remove it, you need to gently rock it from side to side while pulling it up. Do not use excessive force to avoid damaging the tubes or electrical terminals of the motor. If the relay has a fixing metal frame, it must first be bent or unscrewed.
The new device is installed in the reverse order. Make sure that the marking UP or arrow on the relay body faces upward, as it did on the original part. This is important for the proper operation of the internal mechanism. Push the relay onto the contacts until it stops, connect the wires and replace the thermal protection, if it is separate.
Assembly and initial start-up of the refrigerator
After installing the new one starting device it is necessary to return all protective elements to their place. Install the plastic or metal casing and secure the clamp or latches. Make sure that the wires are not pinched or touching hot parts of the compressor or pipes. Then screw the back panel of the refrigerator Vestel to the self-tapping screws.
The first start after repair is a critical moment. Plug in the refrigerator and listen. The compressor should start with a characteristic sound, the relay may click quietly a couple of seconds after start (this is normal for some types). The motor should run smoothly, without vibration or hum.
Check the compressor heating during the first 15-20 minutes of operation. It should be warm, but not scalding hot. If the equipment operates stably and begins to generate cold, the repair can be considered successful. Complete cooling of the chambers will take several hours.
How to understand that the relay has burned out without a multimeter?
Visually you can notice blackening of the plastic, melting of the contacts, or smell a burning smell. Also, if you shake the relay near your ear, there should be no sound of parts falling off inside, although this is not always indicative. The surest way without instruments is the method of exclusion and replacement with a known good one.
Is it possible to repair the relay, or just change it?
Modern relays in refrigerators Vestel are non-separable or conditionally repairable. An attempt to open the case and clean the contacts gives only a temporary effect. Considering the low cost of the part, it is more advisable to make a complete replacement.
Where to buy a relay for a Vestel refrigerator?
Parts can be found in specialized stores of spare parts for household appliances, on radio markets or in online stores. You need to search by refrigerator model or compressor parameters. Universal relays are suitable for many models.
