The situation when Stinol refrigerator makes a loud click but does not start is one of the most common and frightening for owners of household appliances. This sound is often accompanied by a brief vibration of the housing, after which the unit goes silent again, leaving the food without cooling. In this case, there is no need to panic, since the symptoms are quite transparent and in most cases indicate a specific node in the electrical circuit.
The click sound is a mechanical triggering of a protective mechanism or starting device that is trying to start compressor. If this is followed by silence or the cycle repeats after a few minutes, the engine has failed to start. In this article we will analyze in detail which parts fail first, how to carry out initial diagnostics yourself and when it is necessary to call a technician.
It is worth noting that the model range Stinol, including the popular series 101, 102, 103, 104, 106, 107, 110, 116, 118, 120, 122, 123, 124, 125, 126, 128, 130, 132, 134, 205, 242, has a similar design of the starting group. Understanding the operating principle of these components will help you save time and money by determining the nature of the breakdown before the specialist arrives.
The principle of operation of the refrigerator starting group
To understand the nature of the sound, you need to briefly consider the design of the compressor electric motor. The refrigerator motor is asynchronous and requires a short-term connection of an additional winding to create torque. It is this process that is responsible for starting relay, which produces a characteristic click when voltage is applied.
At the moment of switching on, the current in the windings increases, and the relay closes the circuit of the starting winding. The engine begins to accelerate. As soon as the speed reaches the nominal value (approximately 75%), the current drops and the relay opens the starting winding circuit, producing a second, quieter click. If this does not happen, the thermal relay protection comes into play, which also clicks, breaking the circuit to prevent the windings from burning out.
Why Stinol?
Stinol refrigerators produced in the 90s and 2000s, often equipped with Danfoss compressors and starting relays, which have now exhausted their service life. Frequent power surges also negatively affect the sensitive electronics of starting devices.
Thus, a click is a normal operating operation, but if it is not followed by the hum of a running motor, it means that the system has gone into emergency mode. Start-protective relay can be either mechanical (with an inductor) or electronic, but in older models Stinol the first option predominates.
Main reasons for clicks and startup failure
There are several key factors why the refrigerator clicksbut it does not freeze. Most often, the problem lies in the electrical part, but mechanical damage to the very heart of the unit - the compressor - cannot be ruled out.
The first and most common reason is the failure of the start relay. Inside it there is a coil and a movable core, which wears out or burns out over time. The contacts no longer close with the required force, and the engine does not receive the necessary impulse to start. In this case, you hear a series of clicks at intervals of 2-5 minutes.
⚠️ Attention: If you smell burning or see melted plastic in the compressor area, immediately unplug the refrigerator. Operation of such a device can lead to a short circuit and fire.
The second reason is a malfunction of the compressor itself. The motor could “jam” due to exhaustion, lack of lubrication, or destruction of internal mechanical components. In this case, the relay regularly tries to start the engine, a click and a hum is heard, but the shaft does not turn. After a few seconds, the thermal protection turns off the power.
The third reason lies in the interturn short circuit of the electric motor windings. This is a more complex breakdown that requires professional diagnostics with a multimeter. If the winding burns out, the current in the circuit will exceed the norm, which will cause instantaneous operation of the protection and a characteristic sound.
Diagnostics of the starting relay with your own hands
The most likely candidate for replacement is the starting relay. In models Stinol it is usually located on the side wall of the compressor and covered with a plastic casing. To begin diagnostics, you need to turn off the power to the unit, move it away from the wall and remove the back panel.
Remove the box in which the wires are located and carefully disconnect the relay from the compressor. It simply slides onto three pins. Visually inspect the device: if the inside is blackened, there is a burning smell, or traces of melting are visible, the part definitely requires replacement. Also shake the relay near your ear - if you hear a knock, it means the mechanism is destroyed.
If there are visual defects no, you can try to “ring” the contacts with a multimeter, but for a household user it is easier and more reliable to replace it with a known-good device. The cost of a new relay for Stinol is low, and the installation process takes a few minutes.
☑️ Relay diagnostics
Table of symptoms and possible malfunctions
To more accurately determine the problem, compare the behavior of your refrigerator with the data in the table below. This will help narrow down your search.
| Symptom | Probable cause | Required actions |
|---|---|---|
| One click, silence, repeat after 3-5 minutes | Starter malfunction relay or open circuit | Replacing the start relay |
| Click, hum 5-10 sec, click, silence | Compressor jamming or short circuit of windings | Diagnostics of the compressor, possible replacement |
| Series of quick clicks | Unstable voltage or thermostat malfunction | Checking the network and thermostat |
| There is a click, the compressor is hot | Thermal protection has tripped due to overheating | Let it cool for 2 hours, check the ventilation |
It is important to understand that if compressor is hot to the touch, this indicates that there is current in the windings, but there is no mechanical rotation is happening. This is a classic sign of a “wedge” effect or a difficult start.
If the compressor is cold and there are clicks, then the electric current either does not reach the windings, or the relay does not have time to close the circuit. In such cases, replacing the starting device often helps.
Mechanical problems of the compressor
If replacing the relay does not help, the situation gets worse. Most likely, the problem is inside the metal housing of the motor-compressor. In old refrigerators Stinol the cylinder-piston group is often worn out or the valves are destroyed.
There is a “wedging” method, when an increased voltage or impulse is applied to the compressor from a special device to rip the pistons out of place. However, this method is risky and, at home, can lead to permanent failure of the unit. It is better not to experiment without special equipment and skills.
It is also worth checking the integrity of the windings. To do this, use a multimeter to measure the resistance between the contacts on the compressor block (common, starting, working). If the resistance in some area is zero or infinity, the winding is burned out.
⚠️ Attention: It is strictly prohibited to open the sealed compressor housing yourself. Inside there is refrigerant under pressure, and repairs require evacuation of the system and charging with freon, which is only possible in a workshop.
The influence of the thermostat and wiring
Do not discount other elements of the control system. Thermoregulator (thermostat) is responsible for turning the refrigerator on and off. If its contacts are burnt or oxidized, they may not pass enough current to start, causing only weak clicks or sparking.
Check the wiring going to the compressor. In older models Stinol the insulation of the wires hardens and cracks over time, which can lead to short circuits or poor contact in the terminal box. Inspect the wires for melting.
In addition, the fault may lie in the power cable or outlet itself. Try plugging the refrigerator into a different outlet, preferably through a voltage stabilizer, to eliminate problems with the power supply in the apartment.
When you need to call a technician
Independent repair has its limits. If you have replaced the start relay, checked the wiring and thermostat, but Stinol refrigerator continues to click and does not turn on, further diagnostics require the intervention of a professional.
The technician will be able to accurately determine whether the compressor can be repaired or requires a complete replacement. The specialist will also check the system for refrigerant leaks, since low freon pressure can also make it difficult to start the engine, although it is less likely to cause clicks.
Replacing a compressor is a labor-intensive process that requires soldering tubes, evacuating the circuit and charging with refrigerant. It is impossible to do this efficiently without equipment.
Prevention and operating rules
To extend the life of your Stinol and avoid unpleasant clicks in the future, follow simple operating rules. Do not allow equipment to remain idle for long periods of time without being turned on, as this leads to drying out of the oil.
- 🔌 Stable voltage: Use surge protectors or stabilizers, especially in houses with old wiring.
- ❄️ Temperature conditions: Do not set the thermostat to maximum unless necessary, this increases the load on compressor.
- 🧹 Cleanliness of the condenser: Regularly (once every six months) vacuum the radiator grille at the back of the refrigerator to prevent the motor from overheating.
- 🚚 Transportation: After moving, give the refrigerator stand for at least 4-6 hours before turning on, so that the oil flows into the compressor crankcase.
Following these recommendations will significantly increase the service life of the starting group and compressor, keeping your products fresh and your nerves strong.
How long does it last? compressor?
The average service life of a compressor in Stinol refrigerators is 10-15 years, provided there is a stable voltage in the network and proper operation. The starting relay lasts less - on average 5-7 years.
Why does the refrigerator click but does not freeze?
A click means an attempt to start. If there is no frost, then the compressor is not working. Most often, the starting relay has burned out or the motor itself has jammed. The relay needs to be replaced or the compressor repaired.
Is it possible to operate the refrigerator if it clicks?
No, it is not possible. Constant attempts to start without results lead to overheating of the windings and can cause a fire or final failure of the compressor. Disconnect the device before repair.
How much does it cost to replace the start relay with Stinol?
The relay itself is inexpensive (from 500 to 1500 rubles depending on the model), but if you call a specialist to do the work, the price can range from 2000 to 4000 rubles. Replacement takes 15-20 minutes.
A hum after a click is normal?
A short hum (1-2 seconds) upon startup is normal. If the humming continues for 5-10 seconds and ends abruptly with a click, this is a sign that the compressor cannot start (jamming or a problem with the windings).
