The appearance of extraneous sounds in the operation of household appliances is always a cause for concern, especially if it two-chamber refrigeratorworks around the clock. Owners of Belarusian brand appliances often encounter a situation when the device begins to make characteristic clicks that interrupt the silence in the kitchen. These sounds can be either an absolutely normal sign of the system’s operation or a harbinger of a serious breakdown that requires immediate intervention.
To understand the nature of the noise, you need to listen carefully to its frequency and moment of occurrence. Atlant refrigerator may click when starting, while stopping the motor, or even during periods downtime Ignoring these signals sometimes leads to complete failure compressor, the replacement of which is expensive. In this article we will analyze in detail the mechanics of the occurrence of sounds and ways to eliminate them.
The first thing to do is to determine whether the sound is cyclic or single. If clicks are repeated at regular intervals, this often indicates that the system is trying to start. In cases where the sound is heard once after a long period of work, we can talk about thermal expansion of materials. Understanding this difference will be the first step to diagnostics the condition of your unit.
Natural causes of clicking noises
Do not panic ahead of time, as many sounds are normal for the operation of refrigeration equipment. The design Atlant involves the use of various materials that respond to temperature changes. When cooling or heating, plastic, metal and evaporator tubes can contract and expand, producing sounds similar to cracking or light clicks.
This is especially common in new models or immediately after defrosting. Thermoregulator, which is responsible for maintaining the set temperature, also makes a loud noise clicking sound when contacts open or close. This is a signal that the cooling cycle is completed or, conversely, the engine needs to be started. If the refrigerator is level and does not vibrate, such sounds are considered normal.
⚠️ Attention: If the clicks are accompanied by vibration of the body or rattling, check the installation of the refrigerator. An uneven floor can enhance the natural sounds of machinery, creating a false impression of a breakdown.
It is important to distinguish the nature of the sound. Natural thermal expansion usually sounds like a soft crackling sound, similar to a stove cooling down. Mechanical clicks of a relay or starter have a more ringing, metallic tint. Understanding this subtlety will help you not to call for service unnecessarily when the unit simply “gets used” to a new temperature regime.
Malfunctions of the start-up relay
One of the most common reasons why two-chamber refrigerator makes frequent clicking sounds is the failure of the start-up relay relay This small unit is responsible for supplying voltage to the motor windings and protecting it from overloads. When the relay is faulty, it tries to start the motor, a click is heard, but the start does not occur, and the cycle repeats again after a short period of time.
Visually it looks like this: the refrigerator hums for a few seconds, then there is a loud click, and there is silence. After a minute or two, the process repeats. In such a situation the compressor does not have time to start, which can lead to its overheating and wedge. Most often, the problem lies in burnt contacts or malfunction of the bimetallic plate inside the relay.
- 🔌 Symptom 1: Frequent clicks at intervals of 1-3 minutes.
- 🔥 Symptom 2: Heating of the side wall of the housing in the area of the motor.
- 🔇 Symptom 3: Lack of cold in the chambers when the light is on.
Replacing the relay is a relatively simple procedure, but requires compliance with safety precautions. Before starting work, you must completely disconnect the device from the power supply. If you do not have the skills to work with electrical circuits, it is better to entrust this operation to a specialist, since incorrect installation can lead to a short circuit.
Problems with the compressor and its startup
If the relay is working properly, but the Atlant refrigerator continues to click and does not turn on, the problem may lie in the The heart of the unit is the compressor. The engine may be in a "wedge" state where the piston group is stuck in one position. In this case, the starting current increases sharply, the protection is triggered, and we hear a characteristic shutdown click.
Sometimes the cause is an interturn short circuit in the motor windings. In this case, the motor may hum, but not start, making periodic sounds of an attempt to start. A critical sign of a compressor malfunction is the absence of vibration on its body at the moment of clicking, which indicates that the rotor does not even budge.
| Condition | Sound | Case reaction | Probable cause |
|---|---|---|---|
| Normal | Single click | Slight vibration | Thermostat operation |
| Relay malfunction | Series of clicks | Short-term vibration | Burning of contacts |
| Wedge compressor | Humming + clicking | Intense heating, no rotation | Mechanical jamming |
| Winding break | Silence or crackling | Lack of response | Electrical breakdown |
Attempts to “unwedge” the compressor by applying increased voltage at home are risky and often lead to final breakdown of the unit. Modern motors Atlant are sensitive to such interventions. If you suspect this particular malfunction, further operation of the refrigerator is impossible without professional repairs.
Is it possible to start a jammed compressor?
There is a method of starting through a capacitor, bypassing the start relay, but it gives only a temporary effect. The compressor will work from several hours to several days, after which it will completely fail. This solution is only suitable for an emergency in order to preserve food until the technician arrives.
Failures in the operation of the thermostat
The thermostat is a device that controls the temperature inside the chambers and gives a command to turn the refrigerator on or off. If this element fails, the contacts inside it may “stick” or spark, which is accompanied by clicking sounds. In some cases, the refrigerator may not turn off at all, working for wear, or, conversely, may not turn on for a long time.
A common cause of problems is a calibration violation or displacement of the sensitive capillary tube. If the thermostat tube does not fit tightly to the evaporator, the temperature readings will be incorrect. Two-chamber refrigerator In this mode, it begins to work jerkily, constantly clicking and trying to compensate for the loss of cold.
- ❄️ Symptom 1: The temperature in the chambers does not correspond to the set one.
- 🔊 Symptom 2: Clicks are heard chaotically, without reference to operating cycles.
- 💡 Symptom 3: The light inside is on, but the compressor is silent or runs continuously.
To check the thermostat, you often need to ring its contacts with a multimeter at different temperatures. At home, you can try to gently tap the regulator body to dislodge stuck contacts, but this is a temporary measure. The safest way is to replace the unit with a new one, selecting an analogue with the appropriate parameters.
☑️ Diagnostics of the thermostat
The influence of voltage drops in networks
Unstable power supply is the scourge of many regions, and technology Atlant is no exception here. If the voltage in the network drops below the permissible minimum or, conversely, sudden surges occur, the starting relay may not cope with its task. As a result, the compressor cannot reach the required speed and stalls, making a click when the protection is turned off.
Continuous operation in such conditions drastically reduces the service life of the electric motor. The windings overheat, the insulation is destroyed, which ultimately leads to a short circuit. Protective relay in this case, it performs its function, saving the motor from combustion, but frequent clicks indicate that the system is operating in emergency mode.
⚠️ Attention: If the lights flicker frequently in your home or there are power outages, be sure to use a voltage stabilizer to connect the refrigerator. This will extend the life of the compressor and electronics.
You can check for voltage problems using a multimeter or a simple tester in the outlet. If the values go beyond 190-240 Volts, the installation of a stabilizing device becomes mandatory. Ignoring this requirement can lead to expensive repairs not only of the refrigerator, but also of other household appliances.
Self-diagnosis methods
Before calling technicians, you can carry out a number of simple manipulations that will help localize the problem. The first step is to completely defrost the refrigerator. Sometimes an ice plug in the condensate drainage system or freezing on the evaporator creates excess pressure that interferes with the normal operation of the mechanisms.
After defrosting (at least 24 hours with the doors open), turn on the unit. If the clicking stopped and cold appeared, the problem was in the defrosting system or freezing. If the nature of the sounds has not changed, you should move on to a deeper check of the electrical part.
You will need access to the back of the refrigerator, where the compressor is located. Carefully, with caution, inspect the wires for melting, and the assembly itself for traces of soot or oil. Oily stains under the engine may indicate depressurization of the system, which also affects the pressure and operation of the compressor.
- 🔍 Step 1: Visual inspection of the wires and contacts.
- 👂 Step 2: Listening to the nature of the sound (voiced or dull).
- 🌡️ Step 3: Controlling the temperature of the motor housing with your hand (be careful, it may be hot).
If you find obvious signs of a malfunction, such as a burning smell, sparking or strong heating of individual elements, it is better to stop further diagnostics. Operating a faulty appliance can be dangerous. In such cases, it is more advisable to contact an authorized service center for professional troubleshooting.
Why can’t you ignore frequent clicks?
Frequent starting attempts without a successful start create a huge load on the compressor windings. In just a few hours of such work, the engine can overheat to critical temperatures, which will lead to irreversible damage to the insulation and expensive repairs.
When you need to call a specialist
There are a number of situations when independent repair is not only ineffective, but also contraindicated. If, after replacing the relay and checking the voltage in the network, Atlant refrigerator continues to click and does not cool down, the problem lies deeper. This may be a violation of the tightness of the circuit, a clogged capillary tube, or an internal breakdown of the compressor.
To eliminate these malfunctions, specialized equipment is required: a vacuum pump, a pressure gauge station, a charging machine. A qualified technician will be able to accurately determine the pressure in the system, check for the presence of freon and identify leaks using a leak detector.
Also, the help of a specialist is necessary if the compressor itself needs to be replaced. This process includes cutting copper tubes, soldering with a new burner, evacuating the system and charging a strictly defined mass of refrigerant. Errors at any stage will lead to a quick re-breakdown.
How much does it cost to replace a relay in an Atlant refrigerator?
The cost consists of the price of the part itself and the work of the technician. On average, replacing a start protection relay is inexpensive compared to repairing a compressor. However, the exact price can only be given after diagnostics, since tariffs may differ in different regions and services.
Is it possible to temporarily use a refrigerator if it clicks?
If clicks are rare and the cold persists, short-term operation is possible. However, if the clicks are frequent (every 1-2 minutes) and there is no cold, you cannot use such a refrigerator. The food will deteriorate, and the motor will completely fail.
Why does the new refrigerator click?
New equipment may make sounds due to the grinding of parts, the operation of the No Frost system (if any) or thermal expansion of materials. Typically, after a few days of operation, these sounds become quieter or disappear. If the clicks are very loud, this is a reason for a warranty claim.
How to extend the life of the Atlant compressor?
Regularly defrost the refrigerator, do not place it close to the wall for good ventilation, wipe the condenser from behind from dust and monitor the stability of the voltage in the network. These simple measures significantly reduce the load on the motor.
