The situation when a loved one Atlant refrigerator stops freezing can cause panic in any home cook, because food supplies are at risk. If you notice that it is warm in the main chamber, and ice has formed in the freezer or, conversely, everything has completely thawed, you need to act quickly. Primary diagnostics often reveal a simple cause that does not require calling a technician.
In most cases, the problem lies not in a breakdown of the unit itself, but in violation of operating rules or external factors. Two-compressor and single-compressor models can behave differently under the same conditions symptoms. It is important not to ignore the first signs of a malfunction, such as the hum of the engine or the absence of a characteristic click when turning off.
Before disassembling the unit or looking for a service center number, it is worth conducting a basic check. Often users forget about simple things that block the normal operation of the cooling system. Let's figure out what to do first.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately disconnect the device from the power supply and do not try to turn it on again until a specialist arrives.
Checking the settings and operating mode
The most commonplace, but most common The reason is that the thermostat settings are off. If one of the household members accidentally turns the temperature control knob to the “0” or “Min” position, the compressor simply will not start. In modern models with electronic control, the mode may have been lost or the “Holiday” function may have been activated, during which the refrigerator compartment does not cool.
Check the tightness of the door. If sealing rubber the sagging shelf is worn out, dirty, or simply in the way, cold air will evaporate out. The compressor will work non-stop, trying to catch up with the temperature, but due to the constant loss of cold, it will not succeed. Visually, this may appear as a snow coat in one corner of the chamber.
- 🔍 Make sure that the thermostat is set to the operating range (usually this is a division of 2-3 or +4...+5°C).
- 🚪 Check whether the heavy door is warping loading shelves with products.
- ❄️ Inspect the seal around the perimeter for cracks, tears or adhering debris.
If the settings are lost, return them to factory settings. Electronic models Atlant often require a combination of buttons to reset errors. The manual for your model (for example, 4000 or 5000 series) should have reset instructions. If, after adjusting the settings within 2-3 hours, the temperature does not begin to drop, proceed to the next diagnostic stage.
Problems with the No Frost defrosting system
Owners of refrigerators No Frost (without frost) often encounter a situation where the fan is humming, but the cold does not enter the chamber. The reason lies in the automatic defrosting system of the evaporator. If the heating element, defrost thermostat or timer (or electronic module) fails, an ice monolith builds up on the evaporator.
This ice blocks the operation of the fan, which is supposed to drive cold air into the refrigerator compartment. As a result, the freezer may be colder than normal, but the upper compartment may be warmer. Sometimes you can hear the fan trying to turn, but the ice crust interferes with the blades, producing a characteristic crackling sound.
To diagnose this malfunction, partial disassembly of the rear wall of the freezer is often required. However, before this you should try the complete defrosting method.
☑️ Complete defrosting algorithm
⚠️ Attention: When defrosting, it is strictly forbidden to use a hair dryer, hot water or sharp objects to chip ice. Mechanical damage to the evaporator tubes will lead to freon leakage and expensive repairs.
If after a day of defrosting the refrigerator started working normally, but after 1-2 weeks the problem recurred, it means that one of the elements of the defrost system (heating element or sensor) is faulty and requires replacement. Only experienced craftsmen can replace the heating element on their own, since they will need to get to hidden structural elements.
Faults of the compressor and start relay
The heart of any refrigerator is compressor. If it doesn't start, there won't be any cold anywhere. You can determine this by ear: if the unit is silent or, conversely, hums for a couple of seconds and clicks, trying to start, but stalls, the problem is in the starting-protective relay or the motor itself.
The starting relay is a small part that fits onto the contacts of the compressor. Over time, it may burn out or stick. Replacing a relay is one of the simplest and cheapest repair procedures that you can do yourself if you have basic skills in working with tools.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Silent, no light | No power, wiring burned out | Low |
| Beeps for 5-10 seconds and clicks | Faulty starting relay or compressor wedge | Medium |
| Works without stopping | Freon leak or thermostat failure | High |
| The body gets very hot | Wear of the motor, poor ventilation | High |
If after replacing the relay the situation has not changed, and the compressor still hums and turns off, it may be turn-to-turn short circuit windings or mechanical wear of the piston group. In this case, the compressor needs to be replaced, which is a complex procedure that requires evacuation of the system and charging with refrigerant.
How to check the start relay yourself?
Remove the relay from the compressor contacts (after turning off the refrigerator!). Shake it near your ear. If a ringing or knocking sound is heard inside (as if from a broken part), then the relay is faulty and requires replacement. In a working relay, nothing should rattle.
Refrigerant (freon) leak
One of the most unpleasant reasons why Atlant refrigerator does not freeze is a banal freon leak. The refrigerant circulates in a closed circuit, and if a microcrack appears in the tubes or evaporator, the gas escapes. Without freon, heat exchange does not occur.
Often a leak occurs in the foamed part of the case (in the walls), which makes repairs economically impractical. However, sometimes it poisons in accessible places: in sealed connections, on the door heating circuit or at the point where the tubes enter the evaporator. Signs of a leak are:
- 📉 The compressor works constantly without turning off.
- 🌡️ The condenser grille at the back remains cold (normally it should be warm or hot).
- 💨 Absence of the characteristic sound of liquid flowing in the tubes when work.
It is almost impossible to diagnose a leak without special equipment (leak detector, pressure gauges). If you suspect this particular problem, calling a technician is required. The technician will find the leak, seal it and fill the system with new gas.
⚠️ Attention: Freon is a chemical substance. An independent attempt to “top up” the refrigerator with a gas cylinder without evacuation of the system will lead to mixing of the refrigerant with air and moisture, which will completely disable the compressor.
Clogged capillary tube
Another technical reason for the lack of cold is a clogged capillary tube. An ice plug may form inside the thin tube through which freon moves (due to moisture in the system) or blockage with oil breakdown products. The symptoms are similar to a leak: the compressor works, but there is no cold.
Sometimes with such a malfunction you can notice that the condenser grill is only half hot or completely cold, and the compressor itself heats up to very high temperatures. This happens because the gas does not circulate in a circle, but stands in a “dead plug.”
Removing the blockage requires professional intervention. The technician may try to flush the system with high pressure nitrogen or replace the capillary tube. It is impossible to perform this operation efficiently at home.
When you need to call a technician
Not all breakdowns can be fixed with your own hands. If you have checked the settings, defrosted the unit, checked the socket and seal, but Atlant refrigerator it still does not cool, most likely the problem is within the system.
Complex technical faults, such as replacing the compressor, searching for microcracks, replacing the evaporator or electronic module management require special tools and knowledge. An attempt at repair without experience can lead to the fact that a simple and cheap breakdown will turn into a complete replacement of the unit.
Be sure to call a specialist if:
- 🛠️ Soldering of tubes and working with gas is required.
- 🔌 There is a suspicion of an electronics malfunction (control module).
- 🔊 A strong metallic knock or grinding sound appears when the motor is running.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator work, but does not freeze after defrosting?
If less than 5-6 hours have passed after defrosting and there is no temperature, this is normal, the system needs time to return to mode. If more time has passed, the heating element or sensor may have been damaged during defrosting, or moisture may have entered the system, causing an ice jam. The thermostat could also have failed.
Is it possible to operate the refrigerator if it does not freeze, but the light is on?
It is strictly not recommended. The compressor, trying to reach the set temperature, will work non-stop, which will lead to its overheating and burnout of the windings in a short time. It is better to turn off the device until the reasons are found out.
How to understand that the compressor has burned out?
Symptoms: the compressor does not start (silence), or it starts for a couple of seconds with a loud buzzing/clicking sound and immediately stalls. It can also knock out plugs in the apartment when the refrigerator is turned on. In some cases, you can smell the smell of burnt wiring.
How long should a new Atlant refrigerator take to reach temperature?
After the first turn on or long-term transportation, the refrigerator requires 2 to 6 hours to reach temperature, depending on the volume of the chambers and the ambient temperature in the room. Complete stabilization of the mode may take up to 24 hours.
