Refrigerators Samsung are one of the most popular on the market due to the combination of technology, design and reliability. However, even the most modern equipment requires maintenance, especially when it comes to the cooling system. Refilling a refrigerator is not just adding refrigerant, but a complex process that depends on the model, type of compressor and even year of manufacture. In this article we will look at what freons and oils are used in Samsung refrigeratorshow to determine a leak, and why incorrect refilling can lead to breakdown after a few months.
Many users mistakenly believe that all refrigerators are refilled the same. In fact, even within the line there are differences: for example, models with a system require different refrigerants than classic drip refrigerants. In addition, since 2020, the EU and many CIS countries have restrictions on the use of certain types of freons - this also affects the choice of gas station. If you are planning a DIY repair or just want to understand the issue, this article will help you avoid mistakes.

What freons are used in Samsung refrigerators
Refrigerant (freon) is the “blood” of the refrigeration system. The cooling efficiency, noise level and even the service life of the compressor depend on its type. Refrigerators Samsung use several types of freons, and their choice depends on the year of manufacture and technology:
- 🔹 R-134a is the most common freon in models before 2015. It is non-toxic, but has a high global warming potential (GWP), so it is gradually being replaced.
- 🔹 R-600a (isobutane) is an environmentally friendly refrigerant used in modern models (for example, Samsung RB30A3200SA or RT38K6**). It is more energy efficient than R-134a, but requires caution when refueling due to the fire hazard.
- 🔹 R-1234yf is the latest freon that meets the standards
EU F-Gas. Found in premium models since 2020 (for example Samsung Family Hub). Its advantage is minimal impact on the ozone layer. - 🔹 Mixtures (R-404A, R-410A) - rarely, but used in industrial or two-chamber refrigerators with enhanced cooling.
How to find out what kind of freon is in your refrigerator? Usually this information is indicated on compressor nameplate (metal plate on the back wall) or in the technical data sheet. If there is no data, you can focus on the year of manufacture:
| Year of manufacture | Predominant freon | Examples of models |
|---|---|---|
| Before 2010 | R-134a | Samsung RL-33, SR-20 |
| 2010–2018 | R-134a or R-600a | Samsung RB29FSRNDSA, RT43K6** |
| 2019–2022 | R-600a | Samsung RB37A5200SA, RT38A6** |
| From 2023 | R-600a or R-1234yf | Samsung Bespoke, Family Hub+ |
Important: R-600a freon cannot be charged into systems designed for R-134a, and vice versa. This will lead to compressor failure within 1-3 months.
What oil is used with freons in Samsung refrigerators
The oil in the refrigerator performs two key functions: it lubricates the compressor and dissolves freon for circulation through the system. Wrong choice of oil is one of the main reasons for premature wear of the compressor. In refrigerators Samsung the following types of oils are used:
- 🛢️ Mineral oils (for example,
Suniso 3GS) - compatible with R-134a, but not suitable for R-600a. - 🛢️ Synthetic oils (for example,
POE — Polyolester) - universal for R-134a, R-600a and R-1234yf. Used in 90% of modern models. - 🛢️ Polyalkylene glycol oils (PAG) - rare, but found in industrial refrigerators with R-404A freon.
As a rule, in refrigerators Samsung with freon R-600a oil is used POE, and with R-134a mineral or semi-synthetic. Never mix different types of oils - this will lead to the formation of sediment and clogging of the capillary tube.
⚠️ Attention: If you are refilling the refrigerator after repairs (for example, replacing a compressor), be sure to flush the system with new oil. Remains of old oil can react with new freon and cause corrosion.
Signs of a freon leak: when refilling is needed
Freon leak is the most common cause of refrigerator breakdowns Samsung. It occurs due to microcracks in the tubes, corrosion or mechanical damage. You can recognize a leak by the following signs:
- ❄️ Refrigerator does not cool or cools poorly (the temperature in the chamber is above +10°C).
- ⏳ Compressor works without stopping (no on/off cycles).
- 🔊 Appeared hissing sound - this is freon coming out through the crack.
- 💧 On the back wall or floor under the refrigerator oily spots (a mixture of freon and oil).
- 🌡️ Condenser (grid at the back) does not heat up (it is normal should be warm).
If you notice at least one of these signs, do not delay diagnostics. Long-term operation of the refrigerator without freon leads to overheating of the compressor and its failure. On average, the cost of refilling freon is 3–5 times cheaper than replacing a compressor.
⚠️ Attention: Do not try to “top up” freon yourself without looking for a leak. Without eliminating the cause, new refrigerant will leak out in 1-2 weeks, and refilling will be more expensive.
What will happen if the leak is not eliminated?
If you ignore the leak, the compressor will wear out, which will lead to its overheating and breakdown. In addition, oil without freon loses its lubricating properties, and metal parts begin to wear out. As a result, you may need to replace the entire refrigeration circuit, which is comparable in cost to buying a new refrigerator.
Is it possible to refuel a Samsung refrigerator yourself?
Theoretically, you can refuel the refrigerator yourself, but in practice it is risky. To operate you will need:
- 🔧 Vacuum pump (for pumping air and moisture out of the system).
- 🧪 Gauge manifold (for pressure control).
- 🛠️ Cylinder with freon (strictly corresponding to the model refrigerator).
- 🔍 Leak detector (electronic or ultrasonic).
- 📏 Scales (for precise dosing of freon).
Main difficulties:
- Determining the exact amount of freon (excess is just as harmful as underfilling).
- Searching for leaks (without a leak detector this is almost impossible).
- Compliance with safety precautions (freon R-600a explosive!).
If you decide to refuel yourself, follow this checklist:
Disconnect the refrigerator from the network for 24 hours (to equalize pressure)
Check the compressor for operability (measure the resistance of the windings)
Connect the pressure gauge and vacuum pump, pump out the system (at least 30 minutes)
Check the tightness (the pressure should not drop more than 0.5 bar per hour)
Fill with freon in portions, monitoring the temperature at the outlet of the capillary tube -->
Even if the filling was successful, Monitor the operation of the refrigerator for the first 2-3 days: the compressor should turn on/off at intervals of 10–20 minutes, and the temperature in the chamber should stabilize within 4–6 hours.
How much does it cost to refill a Samsung refrigerator at the service
The cost of refilling depends on the type of freon, the complexity of the leak and the region. On average, prices are as follows:
| Type of work | Cost (rub.) | Notes |
|---|---|---|
| Leak diagnostics | 1 500–3 000 | Includes leak detector testing and pressure gauge |
| Freon refilling (without repair) | 3 000–6 000 | The price depends on the type of freon (R-600a is more expensive than R-134a) |
| Leakage elimination + refilling | 5 000–12 000 | Includes soldering of tubes or replacement evaporator |
| Replacement of the compressor + refilling | 10 000–20 000 | Required in case of overheating or interturn short circuit |
The price usually includes:
- 💰 Work of a master (1-2 hours).
- 🛒 Freon and oil (if replacement is required).
- 🔧 Soldering work (when eliminating a leak).
You can save money if:
- 🔍 Find the leak yourself (for example, by oil stains).
- 🛒 Buy freon and oil yourself (but check compatibility with the technician!).
- 📞 Call a technician at home (cheaper than taking the refrigerator to the service station).
⚠️ Attention: Cheap refilling (for example, for 1,000–2,000 rubles) often means that the technician simply I added freon without looking for a leak. In this case, the problem will return in 1–3 months.
Common mistakes when refilling Samsung refrigerators
Even experienced technicians sometimes make mistakes that lead to repeated breakdowns. Here are the most common:
- 🚫 Wrong type of freon —for example, refilling with R-134a instead of R-600a. This leads to increased pressure and breakdown of the compressor.
- 🚫 Overfilling or underfilling - excess freon causes water hammer, and too little - overheating of the compressor.
- 🚫 Ignoring oil -if not add or do not replace the oil, the compressor will run dry.
- 🚫 Poor soldering —poorly sealed tubes will leak in 1–2 months.
- 🚫 Lack of vacuum —moisture in the system leads to corrosion and clogging of the capillary tube.
How to avoid these mistakes?
- Before refilling check the markings on the compressor (the type of freon and oil is indicated there).
- Use only certified freon (cheap analogues may contain impurities).
- After refueling monitor the pressure with a pressure gauge (norm for R-600a: 0.3–0.5 bar at suction).
If after refueling the refrigerator is unstable (for example, the compressor turns on for 1-2 seconds and turns off), this is a sign water hammer —urgently unplug it and call a technician.
How to extend the life of a refrigerator after refueling
Even after successful refueling, the refrigerator requires proper operation to avoid repeated leaks. Follow these recommendations:
- 🔌 Do not overload the compressor —do not place the refrigerator close to the wall (a gap of 5–10 cm is needed for ventilation).
- 🧊 Defrost the refrigerator after refueling (if there was a leak, ice could remain in the system, which would block the capillary tube).
- 🌡️ Control the temperature —in the main chamber it should be +4...+5°C, in the freezer –18°C. If the values differ, this is a sign of a malfunction.
- 🔧 Check the seals - worn rubber bands on the door lead to overload of the compressor.
If the refrigerator Samsung equipped with a system No Frost, after refueling, pay attention to the operation of the fan. If it does not turn on or makes strange sounds, this may indicate icing of the evaporator - diagnostics are required.
FAQ: Frequently asked questions about refilling Samsung refrigerators
Is it possible to refill a Samsung refrigerator with freon from an air conditioner?
No. Air conditioner freons (such as R-22 or R-410A) are not compatible with refrigerators. They have a different pressure and boiling point, which will lead to compressor failure. Always use the freon indicated on the refrigerator nameplate.
How much freon is needed to refill a Samsung refrigerator?
The amount of freon depends on the model and volume of the chambers. On average:
- Single-chamber refrigerators: 30–60 grams.
- Double-chamber (No Frost): 80–150 grams.
- Side-by-Side: 150–250 grams.
The exact amount is indicated in the technical documentation or on the compressor sticker.
What to do if the refrigerator does not freeze after refueling?
Possible reasons:
- The leak has not been repaired (freon leaked out within a few hours).
- Clogged capillary tube (flushing or replacement required).
- The compressor is faulty (check the resistance of the windings).
- Wrong type of freon or oil.
Solution: turn off the refrigerator and call a technician to repair it again diagnostics.
Is it possible to refill a Samsung refrigerator with R-290 (propane) refrigerant?
Technically yes, since R-290 (propane) and R-600a (isobutane) belong to the same class of hydrocarbon refrigerants. However:
- 🔥 Propane is more fire hazardous than isobutane.
- ⚖️ Adjustment of the amount of oil is required (R-290 is less soluble in POE oils).
- ⚠️ Samsung warranty does not apply to refilling with non-original refrigerants.
It is better to use freon recommended by the manufacturer.
How often do you need to refill a Samsung refrigerator?
Under normal conditions, refilling is not required during the entire service life (10–15 years). Freon circulates in a closed circuit and is not consumed. Refilling is needed only in two cases:
- Leakage of freon (due to corrosion, mechanical damage or defects).
- Replacement of the compressor or other elements of the system (new refilling is required).
If the refrigerator requires refilling more often than once every 5 years, this is a sign of a systemic problem (for example, pipe corrosion).
