The situation when Atlant refrigerator makes extraneous sounds often causes panic among owners household appliances. The clicking sounds can be subtle or loud and repeated with alarming regularity. Understanding the nature of these sounds is the first step to saving food and budget.
In most cases, a short click when turning the unit on or off is the normal operation of the automation. However, if the sound has become intrusive, is repeated frequently, or is accompanied by a lack of cold, this is a signal of a malfunction in the electrical circuit or mechanics of the compressor.
Further analysis will help you determine whether an urgent call to a technician is required or whether the problem can be solved yourself by checking simple components. It is important to distinguish between design features of operation and real breakdowns in order to prevent equipment failure.
Natural sounds during compressor operation
Modern and classic models Atlant are equipped with compressors, the operation of which is associated with physical processes of refrigerant compression. When the engine starts, a starting current occurs, which activates the protective starting relay. It is this mechanism that most often produces a characteristic sound.
The sound may resemble a light blow or click, which is heard once when starting and once when stopping the engine. This is normal for single-compressor circuits. If refrigerator works normally, freezes, and there are no other anomalies, there is no need to worry.
Sometimes clicks occur due to thermal expansion of materials. When the temperature changes sharply, the plastic of the inner chamber or the metal case may produce sounds similar to crackling or single blows. This is especially noticeable in new models or after defrosting.
It is also worth considering that some modifications of compressors installed on Atlanthave a noisier start-up cycle. If the equipment was installed a long time ago and behaved quietly, and now a new sound has appeared, this is a reason to listen more carefully.
Malfunction of the starting relay
The most likely cause of repeated clicks, after which the refrigerator does not start, is the failure of the starting relay. This small block is responsible for supplying voltage to the motor windings. If its contacts burn out or the mechanism jams, you hear a series of clicks.
The process looks like this: the relay tries to start the motor, a click is heard, but the start does not occur, the protection turns off the power, and the cycle repeats after a certain interval. At this moment, the compressor may be hot, but cold is not generated in the chambers.
For diagnostics it is necessary:
- 🔌 Disconnect the unit from the network and remove the back panel.
- 🔍 Visually inspect the relay for blackening, melting or cracks.
- 🔊 Gently shake the removed relay: if a ringing is heard inside (as if from a loose nut), it means that the starting coil is broken.
Replacing this element is one of the most common repair procedures Atlant refrigerators. The cost of the part is relatively low, and the replacement procedure itself takes little time if you have basic skills.
☑️ Relay diagnostics
Problems with the thermostat
Thermostat (thermostat) is a device that controls the temperature inside the chambers and commands the compressor to turn on or off. When the contacts open or close, a click is also heard inside the thermostat. In good condition, it is rarely heard, only when changing operating modes.
If thermostat it is faulty, the clicks may become frequent, and the compressor operating cycle will be disrupted. The unit may either not turn on at all, or work non-stop, or turn on for a couple of seconds and stall. In some models Atlant if the sensor breaks down, a loud click is heard, after which the "Alarm" light comes on or the indicator blinks.
To check this unit, you can try to temporarily close the contacts with wires (only for experienced users!). If, when shorted, the refrigerator starts and freezes normally, then the problem lies in the thermostat, which requires replacement.
⚠️ Attention: Before any manipulations with electrical components, make sure that the plug is unplugged from the socket. A short-term closure of the contacts under voltage can lead to electric shock.
In two-chamber models, defrost sensors often fail, which can also malfunction the control system, leading to incorrect sound signals.
Failures in the operation of the electronic module
More modern refrigerators Atlant are equipped with electronic control units that control all processes. If the control board is "buggy", it may send incorrect commands to the start relay, causing chaotic clicks.
Signs of electronics failure:
- 📉 The compressor hums, clicks, but does not start.
- 💡 The indicators on the front panel are flashing.
- 🔄 The refrigerator changes operating modes without permission.
In this case, simply replacing the relay or thermostat will not help. Professional diagnostics of the module is required. Sometimes the problem is solved by flashing, but more often it is necessary to replace burnt elements on the board or the entire unit.
Why are voltage surges dangerous for the module?
Sudden voltage drops in the network can break through the insulation of microcircuits. Even if the refrigerator continues to work, “hidden” defects could remain in the electronics, which will appear over time in the form of chaotic clicks and failures of program cycles.
Mechanical causes and external factors
The source of sound does not always lie inside the electrical circuit. Sometimes The refrigerator clicks due to improper installation or interaction with surrounding objects. The vibration of a running motor is transmitted to the body and can cause pipes or parts to come into contact with furniture.
Check the following points:
- Is the unit standing level? The legs must be adjusted so that the case does not wobble.
- Are the condenser tubes (at the back) touching the walls of the cabinet or neighboring equipment.
- Whether any small part (lid, spoon) has fallen inside the case, which rattles when vibrating.
It is also worth checking mounting of the compressor itself. If the shock absorbers (rubber washers) are dry or the mounting bolts are loose, the motor will vibrate and make knocking noises with each switching cycle.
Comparative table of malfunctions
To quickly navigate the problem, use the table that contains the main symptoms and their probable causes for the equipment Atlant.
| Symptom | Probable cause | Sound character | Difficulty of repair |
|---|---|---|---|
| One click at start/stop | Normal operation of the relay | Quiet, rare | Not required |
| Series of clicks, no cold | Faulty starting relay | Loud, frequent | Low |
| Clicking and the "Alarm" lamp lights up | Thermostat is faulty | Single, with pauses | Average |
| Chaotic clicks, blinking indicators | Electronic module failure | Various | High |
This table helps to initially classify the problem. However, only a specialist can make an accurate diagnosis using a tester and a pressure gauge.
When an urgent call to a specialist is necessary
There are situations when self-repair is not only ineffective, but also dangerous. If, after a series of clicks, you smell a burning smell or see sparking, immediately turn off the power to the device. Further operation may lead to a fire.
Also, specialist help is necessary if:
- 🛑 The compressor hums, clicks, but does not start, and at the same time it is very hot (risk of wedge).
- 💧 Water appears around the unit or inside the chambers or oil.
- 📉 The refrigerator stopped freezing, despite the motor running.
If the compressor is jammed (“wedge”), attempts to start it multiple times can completely (burn) the motor windings, which will lead to the need to replace the entire unit, since the cost of a new compressor with operation is often comparable to the price of a used refrigerator.
⚠️ Attention: If the refrigerator is under warranty, any independent opening of the seals and replacement of parts will void the manufacturer's warranty.
Prevention and care of the starting system
To extend the life of your starting system Atlanta, it is important to ensure a stable power supply. Power surges in the network are the main enemy of electronics and starting relays. Using a surge protector or voltage stabilizer will help smooth out the peaks.
Regularly, at least once every six months, it is recommended:
- Carry out a complete defrost (if the system is not No Frost).
- Rinse the drains holes.
- Check the tightness of the door (so that the motor does not work for wear).
- Clean the rear grille from dust that interferes with the cooling of the compressor.
A clean and dry compressor compartment is the key to quiet operation. Dust, mixed with oil and moisture, can create a conductive layer, causing breakdowns and unstable operation of contacts.
Frequently asked questions (FAQ)
Is it normal for the refrigerator to click immediately after being plugged in?
Yes, this is absolutely ok. At this moment, the starting relay is activated, supplying current to the compressor windings. If after the click the motor hums and after a while cold appears, then the equipment is working properly.
The refrigerator clicks every 5-10 minutes, but does not freeze. What to do?
Most likely, the starting relay has failed or the compressor itself has gone into protection due to overheating. It is necessary to disconnect the device from the mains for at least 2 hours to cool down. If after switching on the situation repeats, a relay replacement or motor diagnostics is required.
Is it possible to replace the relay on an Atlant refrigerator yourself?
Yes, if you have basic skills in working with tools and an understanding of electrical circuits. The relay is removed from the compressor pins. The main thing is to buy exactly the same relay model, since they are selected for a specific power and type of compressor.
Why does an old refrigerator click louder than a new one?
Over time, the mechanical parts of the starting relay wear out, the gap between the contacts increases, which leads to a louder sound when closing. The rubber shock absorbers may also dry out, and the vibration is transmitted to the body more strongly.
