When it comes to repairing a refrigerator, one of the key technical details is the amount of freon in the system. For two-chamber models Atlant this parameter varies depending on the volume of the chambers, year of manufacture and modification of the compressor. A lack or excess of refrigerant leads to malfunctions: from poor cooling to complete failure of equipment. In this article, we will look at how much freon is poured into Atlant refrigerators at the factory, how to determine a leak and what to do if refueling is required.
It is important to understand: information about refilling freon is not always indicated in the passport device. The manufacturer Atlant adheres to standards, but the exact numbers depend on the specific model. For example, for refrigerators with a volume of up to 300 liters, from 60 to 120 grams of refrigerant R-134a or R-600a (isobutane) are usually used. The latest models are often filled with environmentally friendly R-600a, which requires less quantity, but is more sensitive to leaks. If you are planning independent diagnostics or repairs, you cannot do without accurate data.
Why is it important to know the amount of freon in the refrigerator
Freon is the “blood” of the refrigeration system. Its deficiency or excess disrupts heat transfer, which leads to:
- 🔥 Overheating of the compressor — the motor runs without stopping, but the temperature in the chambers does not drop to normal.
- ❄️ Freezing of the evaporator —a thick layer of ice forms on the back wall, blocking air circulation.
- 💰 Increased energy consumption —the refrigerator “eats” electricity, but does not freeze.
- ⚠️ Failure capillary tube —if there is an excess of freon, the pressure in the system exceeds the norm, which can lead to rupture.
In addition, some Atlant models with the system No Frost require precise freon dosage - an error of even 10 grams can disrupt the operation of the fan and evaporator. If you notice that the refrigerator has become noisier, takes longer to reach temperature, or vice versa - it freezes too much, the first check should concern the refrigerant.
⚠️ Attention: Freon R-600a (isobutane) is flammable! If leaked, it forms an explosive mixture with air. Do not use an open flame to find a leak - this can lead to a fire.
Table: amount of freon in Atlant refrigerators by model
Below is a summary table with data on popular two-chamber models. Please note that the values may vary slightly depending on the year of manufacture and modification of the compressor. For accurate information, check the sticker on the compressor or the technical data sheet.
| Refrigerator model | Volume (l) | Freon type | Quantity (g) | Notes |
|---|---|---|---|---|
| Atlant MKhM 2835-080 | 345 | R-600a | 90–100 | Compressor Danfoss, system No Frost in the freezer |
| Atlant MKhM 2843-90 | 343 | R-134a | 110–120 | Old versions (until 2018), drip defrosting |
| Atlant MXM 1701-80 | 270 | R-600a | 70–80 | Compact model, one compressor |
| Atlant MXM 2844-90 | 350 | R-600a | 95–105 | Two compressors, independent temperature control |
| Atlant MHM 1842-66 | 280 | R-134a | 100–110 | Models 2015–2019, drip system |
If your model is not in the table, take a look on chamber volume:
- Up to 300 l - 70-90 g of freon.
- 300-350 l - 90-110 g.
- Over 350 l - 110-130 g.
⚠️ Attention: In refrigerators with two compressors (one for each chamber), freon is charged into each circuit separately. The total volume of refrigerant can reach 180–200 g.
How to determine a freon leak: signs and diagnostics
Refrigerant leakage is one of the most common malfunctions. It can be suspected by the following symptoms:
- ❄️ The freezer does not freeze, but the refrigerator compartment is working normally (or vice versa).
- 🔊 The compressor turns on at 1–2 seconds and turns off - this is a sign that the protection is triggered due to high pressure.
- 🌡️ The temperature in the chambers rises to room temperature, despite the continuous operation of the motor.
- 💨 The condenser (grid on the back wall) does not heats up - this means that freon does not circulate.
For accurate diagnosis, use leak detector (electronic or ultrasonic) or soap solution. Apply the solution to the connections between the pipes, valves and compressor - if there is a leak, bubbles will appear. Pay attention to:
- 🔧 Soldering places —most often a leak occurs here due to vibrations.
- 🔄 Capillary tube —it can rub against the body.
- ⚙️ Filter-drier - it deteriorates over time.
If a leak is confirmed, do not turn on the refrigerator - this can lead to failure of the compressor. It is better to immediately contact a specialist or prepare for refueling yourself.
☑️ What to do before refilling freon
Is it possible to fill freon yourself?
Theoretically, yes, but in practice this requires special equipment and skills. For refueling you will need:
- 🛠️ Vacuum pump — to remove air and moisture from the system.
- 📏 Gauge manifold —to control pressure.
- 🧪 Cylinder with freon —only original, corresponding model.
- 🔥 Burner or soldering iron —for sealing the tubes after refueling.
The process includes several stages:
- Pumping out the residue freon (if any).
- Purge the system with nitrogen to remove moisture.
- Evacuate (at least 30 minutes).
- Refill the refrigerant by weight or pressure.
- Check tightness.
If you have never done such work, it is better to entrust it to a professional. Errors during refueling can lead to:
- 💥 Damage to the compressor due to water hammer (moisture ingress).
- ⚡ Short circuit if the equipment is connected incorrectly.
- 🔥 Fire (if used R-600a).
What will happen if you overfill freon?
Excess refrigerant leads to an increase in pressure in the condenser, which can cause:
- overheating of the compressor and its shutdown protection;
- freezing of the capillary tube and blocking circulation;
- rupture of weak points of the system (for example, soldering).
In some cases, the refrigerator may stop turning on altogether until the problem is resolved.
Where is the information about freon on refrigerator
The manufacturer Atlant usually indicates the type and amount of freon in three places:
- Sticker on the compressor —the brand of refrigerant and its mass are indicated here (for example, “
R-600a 90g»). - Technical passport —in the “Technical Specifications” or “Refrigerant” section.
- The nameplate on the back wall —sometimes the data is duplicated next to the serial number.
If the sticker is worn off or missing, try to find the refrigerator model by the serial number on the website Atlant or in the database of service centers. An alternative method is. contact a specialist with a photo of the nameplate: experienced specialists can determine the type of freon by the appearance of the compressor and tubes.
On some models (for example, Atlant MHM 2835-080), information about freon is indicated in service menu, which is opened with a special combination buttons. However, this method is only suitable for diagnosing electronic faults, and not for determining the charge.
Frequently asked questions about freon in Atlant refrigerators
Let's look at typical situations faced by owners of two-chamber refrigerators of this brand.
Is it possible to replace R-134a to R-600a?
No, these are different types of freon with different properties. R-600a (isobutane) requires less pressure and a different oil in the compressor. Replacement is possible only after a complete rework of the system: flushing, replacing the filter-drier and oil. In most cases, this is not cost-effective - it is cheaper to buy a new one. refrigerator.
How often should you check the freon level?
Under normal conditions, freon does not evaporate - leakage occurs only when there is mechanical damage. Check the system if:
- The refrigerator has become worse at freezing for no apparent reason.
- Traces of corrosion appeared on the tubes.
- You transported the refrigerator in a lying position (risk of damage to the circuit).
In other cases, maintenance once every 5-7 years is sufficient.
What to do if the freon leaks out completely?
If there is a complete leak:
- Disconnect the refrigerator from the network.
- Find the location of the leak (on your own or with the help of a technician).
- Repair the damage (solder the tube or replace the part).
- Refill the system freon with pre-evacuation.
You cannot turn on the refrigerator without freon - this will lead to overheating of the compressor.
How much does it cost to refill freon at a service center?
The cost depends on the region and complexity of the work:
- Leak diagnostics - from 1000 to 2500 rubles.
- Freon refilling (without repair) - 2000-4000 rubles.
- Leak elimination + refilling - 3500-7000 rubles.
Prices are valid for models Atlant without serious damage to the circuit.
Is it possible to use household freon from a can?
No, household freon (for example, for air conditioners) is not suitable for this! refrigerators. They use special refrigerants with precisely calculated properties. Filling with unsuitable freon will lead to:
- Increased load on the compressor.
- Unstable operation of the system.
- Risk of explosion (if mixed R-600a with other gases).
Conclusion: what to do if you suspect problems with freon
If your refrigerator Atlant began to work worse, first check:
- Temperature conditions (the settings may have gone wrong).
- The integrity of the door seals.
- The presence of ice on the evaporator (for models with a drip system).
If these measures did not help, and the symptoms indicate a freon leak (the compressor does not turns off, the condenser is cold), contact the service center. Self-refilling is only possible if you have the equipment and experience. Remember: incorrect dosage of freon reduces the life of the refrigerator by 2-3 times.
