Why does the Atlant two-chamber refrigerator click: normal or broken?

Any refrigerator makes sounds during operation - that’s a fact. But when The two-chamber "Atlant" begins to click with suspicious regularity or volume, owners wonder: is this normal? Or is it time to call a specialist?

Belarusian refrigerators "Atlant" are known for their reliability, but even they are not immune to noise. Clicks can be either part of normal operation or a signal of an imminent breakdown. In this article we will analyze 7 main reasons for clicks from harmless to critical, learn to distinguish them by the nature of the sound and give clear instructions on what to do in each case.

Important: if clicks are accompanied cooling failureblinking indicators or other anomalies - this is no longer a “feature of the model”, but a reason for urgent diagnosis.

1. Thermostat: the main “clicker” in the refrigerator

The most common cause of clicking is work thermostat (thermostat). This device is responsible for turning the compressor on/off when the temperature in the chamber reaches the set values. When the contacts inside the thermostat are activated, a characteristic click is heard, usually single or double.

In models Atlant XM-4021-000, XM-4426-000 and similar ones, the thermostat is located behind the control panel (in the upper part of the refrigerator compartment). A click is heard:

• 🔹 When the refrigerator is plugged in for the first time;
• 🔹 When the compressor starts after defrosting;
• 🔹 When changing the temperature manually (turning the thermostat knob).

How to distinguish normal click of the thermostat from a breakdown? Pay attention to:

1. Regularity: the sound should be repeated at intervals of 1-3 hours (depending on the set temperature).
2. Sequence: click → after 1-2 seconds the compressor starts (a slight hum is heard).
3. No other symptoms: the refrigerator continues to freeze, the light is on steadily.

⚠️ Attention: If the thermostat clicks become more frequent up to 1 time every 5-10 minutesand the compressor runs for less than 1 minute, this is a sign of a freon leak. Diagnostics required! temperature sensor malfunction or freon leak. Diagnostics required!

2. Start-up protection relay: clicks when starting the compressor

The second most frequent source of clicks is start-protective relay, which is located next to the compressor (at the bottom of the rear wall). Its task is to start the motor and protect it from overloads. When triggered, the relay emits loud click, often accompanied by a slight crackling sound.

What does a faulty relay sound like:

• 🔊 Multiple clicks in a row (the compressor does not start) - a sign “sticking” of contacts.
• 🔊 Click + hum of the compressor for 2–3 seconds → shutdown —the relay turns off the motor due to overload.
• 🔊 Click without subsequent hum —break of the compressor winding or relay.

In models Atlant MKhM-1708, MKhM-2835 the relay often fails due to power surges. You can check it yourself:

1. Disconnect the refrigerator from the network.
2. Remove the relay cover (carefully pry it off with a screwdriver).
3. Look at the contacts: if they melted or blackened —the relay must be replaced.

3. Automatic defrosting: clicks in the freezer

In refrigerators Atlant with a system No Frost (for example, XM-6025-031, XM-6321-000) clicks can be heard from the freezer during defrost cycle. This works defrost timer, which turns on the heating element to remove frost.

Characteristic signs:

• 🕒 Clicks are repeated every 8–12 hours (standard defrost interval).
• 💧 After the click, you can hear water flowing into the tray (if you listen).
• ❄️ The freezer temporarily stops cooling (for 15-30 minutes).

If there are clicks when defrosting steel more often or louder, check:

⚠️ Attention: In models Atlant before 2018, the defrost timer could fail due to moisture. If after the click the refrigerator does not freeze longer 1 hour the timer or defrost sensor needs to be replaced.

4. Compressor: when clicks are a harbinger of breakdown

The most alarming scenario is when clicks come from compressor. Normally, it should work almost silently, with a slight hum. If you hear:

• 🔧 Metallic clicks inside the compressor housing —a sign wear of the piston group.
• 🔧 Click + strong vibration —fastenings have loosened compressor.
• 🔧 Click → compressor hums for 1–2 seconds → turns off —turn-to-turn short circuit of the windings.

V models Atlant with inverter compressors (XM-4626-100, XM-6026-031), clicking sounds during startup may be the norm, but only if they disposable and do not repeat more than once per hour.

What to do if you suspect a compressor malfunction:

Disconnect the refrigerator from the network for 10 minutes|Try to start again - if there are clicks repeat, the fault is confirmed|Check the temperature of the compressor housing: if it hot the thermal protection has tripped|Call a technician to check the pressure in the system-->

Can the compressor be repaired?

B In 90% of cases, the compressor must be replaced, not repaired. Average cost of a new compressor for Atlant —from 8,000 to 15,000 ₽ (depending on the model). Repairing the windings or changing the oil gives a temporary effect and does not guarantee durability.

5. Control board: clicks + malfunctions

In modern models Atlant (for example, XM-6026-031, XM-4426-080) is responsible for control electronic board. If it malfunctions, clicks may be accompanied by:

• 📛 Flashing indicators on the panel;
• 🔄 Spontaneous temperature changes;
• ⚡ Failures in the defrosting cycle.

Causes of board failure:

1. Power surges in the network (the most common cause).
2. Moisture on contacts (for example, during defrosting).
3. Failure of a triac or relay on the board.

How to check the board yourself:

1. Disconnect the refrigerator from the network.
2. Remove the top cover (by unscrewing the screws at the back).
3. Inspect the board for blackened elements, swollen capacitors or oxidized tracks.

⚠️ Attention: If traces are visible on the board burnout do not turn on the refrigerator until replacement! This may lead to a short circuit.

6. Fan No Frost: clicks when rotating

In refrigerators with a system No Frost the fan is responsible for air circulation. If you can hear periodic clicks or cracklingwhen it rotates, the probable reasons are:

• 🍃 Ice crust on the blades (interferes with rotation).
• 🔧 Bearing wear (clicks become more frequent over time).
• 🐭 Ingress of foreign objects (pieces of food, packaging).

How to eliminate:

1. Thaw refrigerator on 12–24 hours (if the reason is ice).
2. Check whether the fan rotates freely (turn off the power!).
3. If the bearing is worn, the fan needs to be replaced (~2,500 ₽).

In models Atlant XM-6025-031, XM-6321-000 the fan is located behind the back wall of the freezer. To get to it, you need to remove the inner panel (carefully prying up the plastic clips).

7. Mechanical reasons: what else can click?

Clicks are not always associated with electricity. Sometimes their source is mechanical elements:

• 🧊 Crackling of plastic when the temperature changes (especially in new refrigerators).
• 🔩 Loose fasteners compressor (clicks during vibration).
• 🚪 Door switch (clicks when opening/closing the door).
• 🧲 Magnetic seal (if the door does not fit well).

How to distinguish mechanical clicks:

1. They are not associated with the compressor operating cycle.
2. They most often occur when opening the door, moving products or vibration.
3. Not accompanied changes in cooling.

If clicks are caused by loose compressor mounts, you can tighten them yourself:

1. Disconnect the refrigerator and move it away from the wall.
2. Find the compressor (black cylinder at the bottom).
3. Tighten the fastening bolts with a wrench to 10 mm (do not overdo it!).

FAQ: Frequently asked questions about clicks in the Atlant refrigerator

❓ The refrigerator clicks every 5 minutes - is this normal?

No, this is not normal. Frequent clicks (more than once every 30–60 minutes) indicate:

• Malfunction thermostat (does not work correctly).
• Leakage freon (the compressor is idling).
• Problems with start-protection relay.

Master diagnostics are required.

❓ Why does the refrigerator click but does not freeze?

This is a typical sign:

• Compressor failure (does not start).
• Faulty control board (does not give a signal to start).
• Open circuit in the thermostat.

Urgently disconnect the refrigerator from the network and call a technician!

❓ Is it possible to replace the start-up relay yourself?

Yes, this is one of the few parts that you can replace yourself:

1. Buy a relay for your model (for example, RTK-XM for Atlant XM-4021).
2. Turn off the refrigerator, remove relay cover.
3. Disconnect the wires (take a photo of the connection diagram!).
4. Install a new relay and connect the wires.

If the clicks remain after replacement, the problem is in the compressor or the board.

❓ Why a new Atlant refrigerator? does it click louder than the old one?

Modern models use:

• Inverter compressors (click at startup).
• Electronic boards with relays (louder clicks).
• No Frost systems (the defrost timer works more often).

If the clicks are regular and the refrigerator freezes, this is normal. Over time, the sounds may become quieter.

❓ Clicks. are accompanied by sparks inside the refrigerator - what to do?

This is critical malfunctionImmediately:

1. Unplug the refrigerator.
2. Do not touch metal parts!
3. Call a technician - it is likely electrical wiring breakdown or a short circuit.

Operating the refrigerator in this condition is life-threatening!
