Refrigerators Atlant are one of the most common in the post-Soviet space due to their reliability and maintainability. However, even in such models, over time, malfunctions associated with the refrigerant circulation or condensate removal system occur. The main “arteries” of the refrigerator are tubes for different purposes: freon moves through them, water drains, and pressure is maintained. If you notice that the unit is not freezing well, a meadow has appeared under the bottom, or the compressor is running without stopping, the problem may lie in the tubes.
In this article we will analyze in detail what pipes are in the Atlant refrigeratorwhat each one is responsible for, how to find them in the design and by what signs a malfunction can be determined. Let us separately dwell on capillary tube - the most vulnerable element of the system, which most often gets clogged or freezes. You will also find out whether it is possible to repair the pipes yourself and when it is worth calling a specialist.
The main types of pipes in the Atlant refrigerator and their functions
The design of the refrigerator Atlant (both single-chamber and double-chamber) uses several types of tubes, each of which plays its own role in the cooling or moisture removal cycle. They can be divided into two groups:
- 🔄 Refrigerant tubes — freon circulates through them, providing heat exchange. These include: capillary tube, suction (return) and discharge (high pressure).
- 💧 Drainage tubes — used to drain condensate from the chamber into a special tray. In models with a system No Frost drainage is more complex, since moisture thaws from the evaporator.
Let's look at each in more detail.
1. Capillary tube
This is a thin copper tube with a diameter 0.6–1.2 mmthat connects the condenser (radiator on the back wall) and the evaporator (freezer). Its main task is before it is supplied to the evaporator, where it expands and takes heat from the chamber. This is where problems most often arise: reduce freon pressure before being fed into the evaporator, where it expands and takes heat from the chamber. This is where problems most often arise:
- 🧊 Freezing - if there is little freon in the system or there is moisture, the capillary becomes covered with frost, blocking circulation.
- 🚫 Clogging —particles of oil, dirt or copper oxides clog the lumen, causing the compressor to wear out.
- 🔥 Overheating —if the tube is pinched or deformed, the freon does not cool properly.
In models Atlant older than 2010, the capillary tube is often paired with filter-drier (a small cylinder next to the compressor). In new refrigerators, the filter can be built into the condenser.
2. Suction and discharge tubes
These tubes connect the compressor to the rest of the system:
- 🔵 Suction (reverse) —a thick low-pressure tube through which freon in a gaseous state returns to the compressor. Usually it is cold to the touch.
- 🔴 Discharge is a thin hot high-pressure tube through which freon under pressure enters the condenser. The temperature can reach
60–80°C.
If the discharge tube remains cold when the compressor is running, this is a sign of freon leaks or compressor breakdowns. The suction tube, on the contrary, must be cool - if it is hot, the motor may overheat.
3. Drainage tube
This plastic or rubber tube drains water that forms when the evaporator defrosts (in models with a drip system) or during operation No Frost. In refrigerators Atlant it is usually located:
- 📍 Inside the chamber - behind the back wall (in models with drip defrosting).
- 📍 Behind the refrigerator - leads to the tray above the compressor (in all types).
Typical drainage problems:
- 🚫 Clogging —water does not drain, accumulates in the pan or flows onto the floor.
- 🧊 Icing —if the tube is frozen, condensate does not drain, but ice builds up.
- 🐭 Damage by rodents —relevant for country refrigerators.
Where the tubes are located in the Atlant refrigerator: diagram and photo
To inspect the tubes, it is not necessary to disassemble the refrigerator. Most of them are visible from the outside or after removing the back cover. Here are the main location points:
| Tube type | Location | How to identify |
|---|---|---|
| Capillary | At the back of the refrigerator, next to the compressor | Thin copper tube, often soldered to the filter drier |
| Discharge | From the compressor to the condenser (upper part of the rear wall) | Hot to the touch, diameter ~6 mm |
| Suction | From the evaporator to the compressor (lower part of the rear wall) | Cold, thicker than the discharge (~ 8–10 mm) |
| Drainage | Inside the chamber (behind the back wall) and behind (leads to the pan) | Plastic or rubber, often with a plug |
In models with No Frost (for example Atlant XM 6025-031) the drainage system is more complex: the tube goes from the evaporator through the fan compartment to pallet. In refrigerators with drip defrosting (for example, Atlant MXM 1705), the drainage hole is usually located in the center of the rear wall of the freezer.
Attention! Before inspecting the tubes, be sure to unplug the refrigerator and wait until the compressor has cooled down. The discharge tube can be very hot!
What does the capillary tube look like in the Atlant refrigerator?
It is a thin copper tube with a diameter smaller than the little finger, often wrapped together with the suction tube with black insulating tape or polyurethane foam. There may be a solder joint at the junction with the filter drier. In new models, the capillary is sometimes hidden under the plastic casing of the condenser.
Signs of tube malfunctions and their diagnosis
Problems with tubes manifest themselves differently depending on their type. Here are the key symptoms that should alert you:
1. Problems with the capillary tube
If the capillary is clogged or frozen, the refrigerator:
- ❄️ Stops freezing (it’s warm in the freezer, the temperature in the refrigerator compartment is too high).
- ⏳ The compressor works without stopping or turns on for short periods intervals.
- 🔊 An uncharacteristic hum or gurgle appears (freon cannot pass through the blockage).
For diagnostics:
- Turn off the refrigerator and defrost it for 12-24 hours.
- Check the temperature capillary tube: if it is ice-cold and the rest of the tubes are warm, there is a blockage.
- Shine a flashlight on the filter drier: if it is blackened or swollen, it needs to be changed along with the capillary.
2. Malfunctions of the discharge or suction tubes
Symptoms:
- 🔥 Discharge tube is cold when the compressor is running → freon leak.
- 🥶 Suction the tube is hot → compressor overheating or there is a blockage in the capillary.
- 💨 The compressor hums, but does not start → possible pipe break (rare, but happens with mechanical damage).
To check:
- Inspect tubes for cracks, dents or traces of oil (if there is a leak, freon evaporates, but the oil remains).
- Check the temperature: the discharge should heat up 5-10 minutes after starting, the suction should remain cool.
3. Clogged drainage pipe
Signs:
- 💦 Water accumulates under the vegetable drawers or flows onto the floor.
- 🧊 Ice builds up in the freezer, although defrosting was carried out recently.
- 😷 Unpleasant smell from the refrigerator (stagnant water in the drainage becomes moldy).
Diagnostics:
- Look into the drainage hole inside the chamber - if it is clogged with debris, clean it with a cotton swab.
- Blow tube using a medical bulb or a bicycle pump (without fanaticism, so as not to damage it).
Can you fix the tubes yourself?
Some problems with tubes in the refrigerator Atlant can be fixed without calling a technician, but there are operations that require special equipment. Let's figure out what you can do with your own hands and what you can't.
✅ What you can fix yourself
- 🧹 Cleaning the drainage tube - blockages are eliminated by washing with warm water and soda or blowing. In difficult cases, you can use a wire with a hook.
- 🔧 Replacing the drainage tube —if it is cracked, it can be easily bought at a spare parts store and installed by removing the back cover.
- 🧊 Defrosting the capillary tube —if it is frozen due to a lack of freon, sometimes complete defrosting for 24 hours helps.
❌ What cannot be repaired without a master
- 🔄 Cleaning or replacing the capillary tube —requires a vacuum pump, soldering equipment and refilling with freon.
- 🛠️ Repair of discharge/suction tubes —if freon leaks, the system needs to be completely refilled.
- 🔥 Replacing the filter drier —always paired with a capillary and requires professional equipment.
Attention! If you suspect a freon leak (the compressor works, but does not freeze, the tubes do not heat up), do not try to solder the tubes yourself. Freon under pressure can ignite, and its vapors are toxic. Contact the service center.
Disconnect the refrigerator from the network
Defreeze for 12+ hours
Write down the model (located on sticker inside the chamber)
Prepare access to the back wall (move away from the wall)
Take photographs of problem areas (if there are visible damages)-->
How to extend the life of Atlant refrigerator tubes: prevention
Many tube breakdowns can be preventable if you follow simple operating rules. Here are the key recommendations for refrigerators Atlant:
- Regular defrosting - even if you No Frost, turn off the refrigerator for 12 hours every 6-12 months. This will prevent the accumulation of ice in the drainage and freezing of the capillary.
- Humidity control —do not place hot foods or open containers with liquid in the refrigerator. The steam condenses and clogs the drainage.
- Cleaning the drainage hole - wash it with water and soda or citric acid every 3 months.
- Checking the seal - if the door does not close tightly, the compressor is working on wear, and the tubes overheat.
- Protection against rodents —if the refrigerator is in the country, cover the drainage tube at the back with a metal mesh.
For models with a drip system (Atlant MXM 2835, MX 2823) it is especially important to monitor the condition of the back wall of the freezer. If thicker ice grows there 5–7 mm, it means that the drainage cannot cope or there is a problem with the thermostat.
Attention! In refrigerators Atlant with a system No Frost (for example, XM 4626-100), you cannot use sharp objects for defrosting - you can damage the evaporator tubes, which are hidden behind plastic panels.
Table of tube malfunctions and their elimination
To quickly navigate the problem, use this table:
| Symptom | Probable cause | What to do |
|---|---|---|
| The refrigerator does not freeze, the compressor runs non-stop | Clogged capillary tube or freon leak | Call a technician to diagnose and refills |
| Water under the refrigerator | Drain tube clogged or crack in pan | Clean the tube or replace pan |
| Discharge tube is cold | Leak freon or compressor breakdown | Checking for leaks, refilling or replacing the compressor |
| Ice in the drainage hole | Drain freezing due to a faulty thermostat | Defrost for 24 hours, replacing the thermostat |
| Hum and vibration during operation | The capillary tube touches the body or condenser | Carefully bend the tube, secure it with insulation |
If your refrigerator model Atlant released before 2015, please note that they may have used less durable materials for the tubes (for example, aluminum instead of copper in the capillary). In this case, the risk of blockages and leaks is higher.
⚠️ Attention: The characteristics of the tubes (diameter, material, location) may vary depending on the model and year of manufacture of the refrigerator. For an accurate diagnosis, check the instructions for your model or the diagram on the back cover.
FAQ: Frequently asked questions about tubes in the Atlant refrigerator
Is it possible to change the capillary tube yourself?
Theoretically yes, but in practice this requires special equipment: vacuum pump, freon cylinder, soldering torch and pressure gauges. Without experience, you risk damaging the compressor or condenser. It is better to entrust this work to a specialist.
Why does the drain tube constantly freeze?
The reasons may be different:
- Wear of the door seal (warm air enters).
- Faulty thermostat (the refrigerator operates without stops).
- There is a blockage in the capillary tube (freon does not circulate, the freezer freezes).
First check the seal and defrost the refrigerator for a day. If the problem persists, call a specialist.
What to do if water with an unpleasant odor flows from the drainage pipe?
This is a sign of water stagnation and bacterial growth. Clean the tube with a wire, rinse with a solution of soda (1 tablespoon per 1 liter of water) and pour hydrogen peroxide into the hole for disinfection. Repeat the procedure 2-3 times. 50 ml hydrogen peroxide for disinfection. Repeat the procedure 2-3 times.
How to understand that there is a freon leak in the refrigerator?
Main signs:
- The compressor works, but does not cool.
- The discharge tube does not heat up.
- There are oil stains on the back wall (freon evaporates, oil leaks out).
The leak can only be repaired by a service center - you will need to solder the tubes and refill the refrigerant.
How much does it cost replacing tubes in the Atlant refrigerator?
The cost depends on the type of tube and region:
- Cleaning the capillary tube - from
2 500 ₽. - Replacing the drainage tube - from
1 000 ₽(plus the cost of the part). - Freon leak repair with refilling - from
3 500 ₽.
In some cases, it is cheaper to buy a used refrigerator than to repair an old one (for example, if you need to replace the compressor).
