Does the Atlant refrigerator click when turned on: normal or broken?

You have turned on refrigerator Atlant, and it began to make rhythmic clicks - sometimes rare, sometimes frequent, sometimes accompanied by humming or pauses? Don’t rush to panic: in 80% of cases this is normal operation of the system. But how can you distinguish a normal sound from a malfunction signal? In this article, we will analyze all possible causes of clicks - from harmless relay operation to serious breakdowns of the compressor or thermostat.

We analyzed reviews from owners of models Atlant MXM 1705-80, Atlant XM 4026-000 and other popular series, as well as technical documentation from the manufacturer. It turned out that the nature of the clicks directly depends on the stage of operation of the refrigerator: when first turned on after defrosting, during the cooling cycle, or when trying to start a faulty compressor. Below you will find checklists for self-diagnosis and instructions on what to do in each case.

Why does the Atlant refrigerator click when turned on: normal sounds

Clicks in the refrigerator Atlant are not always a sign of a breakdown. Many sounds are associated with the operation of start-protective relay i thermostat, which are triggered each time the compressor is turned on. Let's consider the “healthy” reasons:

• 🔌 Compressor relay activation. When power is applied, the relay closes its contacts to start the motor - this is accompanied by one loud click. In models with an inverter compressor (for example, Atlant XM 6025-031), the sound may be quieter.
• ❄️ Switching the thermostat. When the temperature in the chamber reaches the set value, the thermostat opens the circuit - this is also accompanied by a click. In two-chamber refrigerators (Atlant MHM 2835-90), there can be two such sounds: for the freezing and refrigerating chambers.
• ⚡ Automatic defrosting No Frost. In models with a system No Frost (for example, Atlant XM 4426-100), the heater periodically turns on to defrost the evaporator - this can also be accompanied by relay clicks.

How to distinguish normal clicks from a breakdown? Pay attention to rhythm and frequency:

• ✅ Healthy rhythm: 1-2 clicks when starting, then a pause (the compressor is running), then 1 more click when turning off. The interval between cycles is 10–30 minutes.
• ❌ Suspicious rhythm: frequent clicks (every 1–3 seconds) without starting the compressor, or the compressor turns on for 1–2 seconds and immediately turns off.

Clicks without starting the compressor: failure of the relay or starting capacitor

If the refrigerator Atlant clicks every 5-10 seconds, but the motor does not start, this is a sure sign of a problem with start-protective relay or capacitor. Let's consider both cases:

1. Faulty start-up relay

The relay is responsible for starting the compressor and protecting it from overheating. If it breaks down, it can:

• 🔊 Click with a pause of 3–5 seconds —the relay tries to start the motor, but it does not respond.
• 🔥 Smell of burning —a sign of burning of the contacts inside the relay.
• 🛠️ Have visible damage (melted body, cracks).

How to check the relay yourself? Unplug the refrigerator, remove the back cover and locate the relay (usually attached to the compressor). Shake it gently - if you hear knocking or rattling, this is a sign of a malfunction. You can also replace the relay with a known working one (for example, from another refrigerator) and check whether the compressor will start.

What does the start-up relay look like in the Atlant refrigerator?

It is a small plastic box (usually black or gray) with outgoing wires, attached to the compressor body. It may have markings like “DANFOSS 103N0210” or similar. In some models, the relay is integrated into a single unit with a thermostat (for example, in Atlant MXM 1708).

2. Failure of the starting capacitor

The capacitor helps the compressor overcome the initial load when starting. If it is faulty, the motor will not be able to start, and the relay will click idle. Signs:

• ⚡ The refrigerator clicks, but the compressor does not even hum.
• 🔋 The condenser is swollen or leaking (visible during visual inspection).
• 📉 There is no voltage on the capacitor (checked with a multimeter).

To diagnose the capacitor:

1. Disconnect the refrigerator from the network.
2. Discharge the capacitor by shorting its terminals with an insulated screwdriver handle (be careful - there may be a discharge!).
3. Run the capacitor with a multimeter in capacitance measurement mode. The normal value is about 20–40 μF (the exact data is indicated on the capacitor body).

⚠️ Attention: If the capacitor is swollen or leaking, it must be replaced immediately - this can lead to a short circuit and fire!

Clicking noise: problems with the compressor

If the refrigerator Atlant not only clicks, but also buzzes for 1-2 secondsand then turns off - the problem is most likely in the compressor. Possible reasons:

In some cases, the compressor can be “reanimated” yourself If it is. hums, but does not start due to jamming, try:

1. Disconnect the refrigerator from the network for 10-15 minutes.
2. Turn the compressor by hand by the flywheel (if available) 1-2 turns clockwise.
3. Turn on the refrigerator again If the compressor starts. - the problem was the piston jamming.

⚠️ Attention: If the compressor hums but does not start, do not try to turn it on repeatedly! This can lead to overheating of the windings and final failure. Maximum - 2-3 attempts with an interval of 10 minutes.

Thermostat clicks: how to check and replace

The thermostat (or thermostat) is responsible for maintaining set temperature. If it breaks down, the refrigerator may:

• 🔊 Click without stopping —the thermostat triggers falsely.
• ❄️ Do not turn on the compressor at all —the thermostat contacts do not close.
• ➰ Work without stopping —the contacts are “stuck” in the closed state.

How to check the thermostat in the refrigerator Atlant:

1. Disconnect the refrigerator from the network.
2. Remove the thermostat knob and the protective casing (usually secured with latches or screws).
3. Find the thermostat - this is a small box with a tube going to the evaporator.
4. Disconnect the wires from the thermostat and test it with a multimeter in resistance testing mode. At room temperature, the contacts should be closed (resistance ~0 Ohm).
5. Place the thermostat in cold water - the contacts should open. If this does not happen, the thermostat is faulty.

Replacing the thermostat in refrigerators Atlant usually does not cause difficulties. The main thing is to choose a similar model (for example, for Atlant MXM 1840 a thermostat K59-L1938 or Danfoss 077B6is suitable). When installing a new thermostat, be sure to:

• 🔧 Connect the wires correctly (usually they are marked with letters: L - phase, N - zero, 3 or 4 — output to the compressor).
• 📏 Adjust the position of the tube —it should fit snugly to the evaporator.
• 🔄 Check operation —after replacement, the refrigerator should start and turn off after 10-20 minutes.

Clicks in Atlant refrigerators with the No Frost system

In models with No Frost (for example, Atlant XM 4626-100 or Atlant MXM 2842-90) clicks can be associated not only with the compressor, but also with the operation of the automatic defrosting system. Let's look at the features:

• ⏱️ Defrost timer. Every 8-12 hours the heater is turned on to defrost the evaporator. In this case, clicks are heard from the timer relay (usually located next to the control board).
• 🔥 Evaporator heater. When you turn on the heater, you may hear a slight click from its relay. If the heater is faulty, the refrigerator will be covered with ice and the fan will hum.
• 🌀 Fan. If the fan touches ice or foreign objects, this may be accompanied by clicking or grinding noises. In this case, defrosting is necessary (at least 12 hours!).

How to diagnose a problem with No Frost:

1. Turn off the refrigerator and defrost it for 12-24 hours.
2. After defrosting, turn on the refrigerator and listen:
   • If the clicks disappear, the problem was icing of the fan or sensors.
   • If the clicks remain, check the defrost timer and heater.

Check the operation of the fan: with the door open, it should start in 1-2 minutes.

⚠️ Attention: If the refrigerator stops blowing cold air, but the compressor is working, the fan is most likely broken or the evaporator is frozen. Do not try to mechanically remove ice with sharp objects - this may damage the freon tubes! No Frost The cold air has stopped blowing, but the compressor is working - most likely the fan is broken or the evaporator is frozen. Do not try to mechanically remove ice with sharp objects - this may damage the freon tubes!

Clicks after defrosting: what to check first

If the refrigerator Atlant started clicking after defrosting, the reasons may be as follows:

• 💧 Moisture on electrical components. Condensation may have shorted the contacts of the relay or control board. In this case, you need to dry the refrigerator for 1-2 hours with the door open.
• ❄️ Icing of the evaporator. If defrosting was insufficient, ice may block the fan (in models with No Frost) or the temperature sensor.
• 🔌 Control board failure. An abrupt power cut during defrosting may cause an error in the operation of the electronic module. Try resetting the settings by turning off the refrigerator for 5-10 minutes.

What to do if the clicking does not go away after defrosting:

1. Check whether the drainage holes are frozen (they should be clean, without ice).
2. Make sure the door closes tightly - sometimes the seal becomes deformed after defrosting.
3. If the refrigerator does not start, check the fuse (in some models it is located on the control board).

In models with electronic control (for example, Atlant XM 6321-000a reset may be required after defrosting errors. For this:

1. Unplug the refrigerator for 1 minute.
2. Turn it back on.
3. Press and hold the "Super Freeze" (or "Fast Cool") button for 5-10 seconds.

When to call a technician: signs of serious damage

Some faults that cause clicking noises in the refrigerator Atlantrequire professional repair. Contact a technician if:

• 🔥 Smells of burning or plastic —this is a sign of a short circuit or overheating of the compressor windings.
• ⚡ Clicks are accompanied sparking —the wiring or relay contacts may be damaged.
• 📉 The refrigerator is not freezing, but the compressor is hot —a freon leak or a clogged capillary tube is likely.
• 🔊 The clicks have become louder over time —this may indicate wear on the compressor or relay.

The cost of repair depends on the type of breakdown:

⚠️ Attention: If the refrigerator Atlant is under warranty, do not disassemble it yourself! This may void your warranty. Contact the service center with a receipt and warranty card.

FAQ: Frequently asked questions about clicking noises in the Atlant refrigerator

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

In new models, more sensitive ones are often installed start-up relays and electronic control boards that may click louder. Also, in refrigerators with inverter compressors (for example Atlant XM 6026-031), the sound of the relay may differ from conventional models. If the clicks are rhythmic and the compressor starts, this is normal.

The Atlant refrigerator clicks and does not turn on after the lights are turned off. What to do?

Perhaps the compressor protection against power surges has tripped. Try:

1. Disconnect the refrigerator from the network for 10-15 minutes.
2. Check the voltage in the outlet (should be 220-230 V).
3. If the clicks are repeated after turning on, check the relay and capacitor (see section above).

If the problem recurs frequently, install a voltage stabilizer.

Is it possible to replace the relay in the Atlant refrigerator yourself?

Yes, replacing the start-up relay is one of the simplest operations. You will need:

• New relay (select according to the compressor model, for example, for Atlant MHM 1840 suitable DANFOSS 103N0210).
• Screwdriver and pliers.
• Multimeter for checking contacts.

Algorithm:

1. Disconnect the refrigerator from the network.
2. Remove the relay from the compressor (usually it is attached to a latch or screw).
3. Disconnect wires, remembering their location (take a photo!).
4. Install a new relay and connect the wires.
5. Check the operation of the refrigerator.

The Atlant refrigerator clicks with No Frost, but does not freeze?

Probable reasons:

• 🔄 The defrosting timer is broken —the refrigerator is stuck in defrosting mode. The timer needs to be replaced.
• 🔥 The evaporator heater is burnt out —ice is blocking the air circulation. The heater needs to be replaced.
• ❄️ The evaporator is frozen —try defrosting the refrigerator for 24 hours. If the problem persists, check the door seal.

How to reduce the clicking noise in the Atlant refrigerator?

If the clicks are not associated with a breakdown, but irritate you, try:

• 🔧 Secure the compressor relay - sometimes it rattles due to weak fixation.
• 🔌 Install the refrigerator on a flat surface - vibration can amplify sounds.
• 📦 Check the back cover —if it is poorly secured, the clicks will be louder.

If the sound has become louder over time, this may indicate wear on the relay or compressor. In this case, it is better to call a technician. diagnostics.
