The Atlant refrigerator clicks during operation: 7 reasons and what to do

The refrigerator Atlant is a reliable assistant in the kitchen, but sometimes its operation is accompanied by unexpected sounds. Clicks during operation they can either return to normal or signal an imminent breakdown. Let's figure out which sounds are safe and which require the intervention of a specialist or self-repair.

Many owners get scared when they hear rhythmic or single clicks from the refrigerator body. However, in 80% of cases this is the normal operation of the relay, compressor or system No Frost. But how to distinguish “healthy” sounds from alarming ones? This article contains a checklist for diagnostics, a table of typical faults and step-by-step instructions on what to do if the clicks become too loud or frequent.

We should immediately note: Atlant (especially the models MHM 1705-80, MX 2824-66 and series Nova Frost) are structurally designed to provide sound accompaniment to the operation. But there are nuances that depend on the age of the equipment, operating conditions and even... the temperature in the room. Next are the details.

1. Normal clicks: when you shouldn’t worry

If the refrigerator Atlant clicks at intervals 10–30 minutes, most likely this is the normal operation of one of the three nodes:

• 🔄 Start-protective relay — turns the compressor on/off. A clicking sound is heard when the engine starts and stops. In models with inverter compressor (for example, Atlant XM 4625-100) the sound is quieter, but still noticeable.
• ❄️ No Frost System —in refrigerators with this technology (series NF, MNF), clicks are made defrost timer. It operates every 6–12 hours, including the heater to remove frost.
• 🧊 Thermostat - a mechanical or electronic sensor that opens the circuit when the set temperature is reached. A click is heard when the contacts are activated.

How to distinguish normal clicks from a breakdown?

⚠️ Attention: If sounds are accompanied long hum of the compressor (more than 1-2 minutes without pauses) or the refrigerator has stopped freezing, this is a reason for diagnosis. In other cases, rhythmic clicks are part of the operation of the equipment.

In models Atlant up to 2018 release the start-up relay may click louder due to design features. New refrigerators (for example Atlant MHM 2735-90) use silent relays, but it is impossible to completely get rid of sounds - this is the physics of the compressor.

2. Dangerous clicks: signs of malfunction

If the refrigerator Atlant clicks more often than once every 3-5 minutes, accompanied by other symptoms (does not freeze, the body gets very hot, indicators flash) - this is a signal of a possible breakdown. Let's consider typical cases:

• 🔌 Faulty start-up relay —the clicks are frequent, but the compressor does not start (or turns on for 1-2 seconds and turns off). Reason: oxidation of contacts, mechanical wear or overheating.
• ⚡ Problems with the compressor - if after a click the motor tries to start, but only a hum or crackling is heard, the piston may be turn-to-turn breakdown of the winding or jammed.
• 🌡️ Thermostat failure —the refrigerator clicks randomly, the temperature in the chambers does not correspond to the settings. In models with electronic control (for example, Atlant MHM 2832-90), an error may flash E1 or E2.
• 🔥 Overheating of the condenser —if the clicks are accompanied by a hot housing at the back, a freon leak or clogged capillary tube is possible.

The most dangerous scenario is when the refrigerator clicks, but does not turn on. This may mean:

1. Breakage of the compressor winding.
2. Failure of the control board (in models with display).
3. Power problems (check the outlet and power cord!).

For initial diagnosis, perform a simple test:

Unplug the refrigerator for 10 minutes|Plug it back in and listen to the sounds|Check if the compressor starts after a click|Evaluate the temperature in the chambers after 1-2 hours|See if the error indicators are flashing-->

3. Table: clicks and their meaning

If your case is not included in the table, pay attention to additional symptoms:

• 💡 Are the indicators on the panel flashing?
• ❄️ Has frost formed on the back wall?
• 🔊 Have the clicks become louder over time?

4. Self-diagnosis: step-by-step instructions

Before calling a technician, try checking the refrigerator Atlant on your own. You will need:

• Screwdriver (Phillips/flathead).
• Mulmeter (to check the relay and thermostat).
• Flashlight (to inspect the back wall).

Step 1. Checking the start-up protection relay

1. Disconnect the refrigerator from the network.
2. Remove the protective cover from the compressor (it is secured with latches or screws).
3. Inspect the relay for melting or rust. If the contacts are blackened, the part is subject to repair. replacement.
4. Test the relay with a multimeter in resistance test mode. There should be resistance between the contacts 3 and 4 (on the relay diagram) 20–40 Ohm.

Step 2. Thermostat diagnostics

In mechanical thermostats (installed in models Atlant MXM 1705-80, MX. 2808-50), a common cause of clicking is contact wear. To check:

1. Find the thermostat (usually located inside the chamber, under the plastic cover).
2. Remove the terminals and test the contacts with a multimeter. At room temperature, they should be closed.
3. Turn the thermostat knob: if you hear a click, but the contacts do not open, the part is faulty.

Step 3. Inspect the compressor

If the relay and The thermostat is fine, but the refrigerator clicks and does not freeze:

1. Try to manually turn the compressor shaft (via the relay). If it does not rotate, the motor is jammed.
2. Check the compressor windings with a multimeter:
   • Resistance between contacts C-S (common and starting winding): 20–30 Ohm.
   • Resistance between C-R (common and working winding): 10–15 Ohm.
   • Resistance between S-R (starting and working): 30–40 Ohm.

If the readings are different or there is a break, the compressor must be replaced.

What to do if the compressor hums but does not start?

This symptom often indicates interturn closure or a malfunction starting capacitor. Try replacing the capacitor (the part costs 300–800 rubles). If this does not help, you will need to replace the compressor (in workshops Atlant this will cost 5,000–12,000 rubles depending on the model).

5. When to call a technician: 5 warning signs

Not all breakdowns can be fixed on your own. Contact a specialist if:

• 🔧 The refrigerator clicks, but the compressor does not start at all (possible winding breakage or jamming).
• ⚡ Appearances on the body or plug traces melting is a sign of a short circuit.
• 🌡️ The temperature in the chambers rose higher +10°C, despite the relay clicks.
• 💦 A puddle has appeared under the refrigerator, and clicks are accompanied by hissing (freon leak).
• 📛 An error is displayed on the display E1, E3 or E5 (in models with electronic control).

Cost of repairs in service centers Atlant (for 2026):

• Replacement of the start-protection relay: 1,200–2,500 rub. (with work).
• Replacement of the thermostat: 1,500–3,000 rub.
• Diagnostics compressor: 800–1,500 rub. (excluding replacement).
• Freon refilling: 3,500–6,000 rub.

⚠️ Attention: If the refrigerator Atlant is under warranty (up to 3-5 years depending on the model), do not disassemble it yourself! This will result in loss of warranty. Contact an authorized service center.

6. Prevention: how to reduce the noise of a refrigerator

Even if clicks are normal, they can be made quieter. Tips for refrigerators Atlant:

• 📍 Install the refrigerator at a level —vibration from an uneven surface increases noise. Use adjustable feet.
• 🧲 Check the door seal —if it is worn out, the compressor runs longer, which increases the number of clicks.
• 🧹 Clean the capacitor (grid at the back) for dust every 6 months. Overheating increases the load on the relay.
• ⚡ Connect through a surge protector - voltage surges shorten the life of the relay and compressor.
• ❄️ Do not place hot products to the chamber - this makes the compressor work harder.

For models with No Frost (Atlant MKhM 2726-90, MKhM 2832-90 etc.) important:

1. Defrost the refrigerator once a year (despite the auto-defrost system).
2. Check the operation of the fan - if it is clogged with ice, the defrost timer clicks will become more frequent.

7. Frequently asked questions about clicking noises in Atlant refrigerators

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

Modern models (for example Atlant XM 6025-031) use more sensitive relays and electronic thermostats, which can click louder due to precise temperature control. Also, new refrigerators are often equipped with inverter compressorsinverter compressors

If the clicks seem too loud, check:

• Correct installation (the refrigerator should not touch the walls or furniture).
• Temperature settings (mode Super Freeze increases the frequency of clicks).

Does the Atlant refrigerator click after defrosting - is this normal?

Yes, after defrosting, clicks may become more frequent due to:

• Active operation of the compressor to set the temperature.
• Triggering of the defrost timer (in models with No Frost).
• Possible moisture on the relay contacts (if defrosting was sloppy).

If after 12–24 hours the frequency of clicks has not returned to normal, check:

• Is the door closed tightly (the seal could be deformed from ice).
• Is there ice on the evaporator (in models with No Frost this indicates a malfunction of the defrost system).

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

Yes, this is one of the simplest procedures. You will need:

1. Buy an original relay (for example, RTK-1 or RTP-1 for models Atlant).
2. Disconnect the refrigerator from the network.
3. Remove the compressor cover and disconnect the old relay (remember the location of the wires!).
4. Install a new relay, connect the wires in the same order.

Important: Do not touch the compressor tubes - they may be hot. If after replacing the relay the compressor does not start, the problem may be in the compressor itself or in the compressor. thermostat.

The Atlant refrigerator clicks and the light is flashing - what to do?

A flashing light (or indicator on the display) + clicks usually mean:

• Failure of the control board (in models with electronic block).
• Problems with the temperature sensor.
• Short circuit in the circuit.

Try:

1. Turn off the refrigerator for 15-20 minutes, then turn it on again (error reset).
2. Ring the power cord and plug for a break.
3. If the blinking continues, call a technician to diagnose the board.
