What Indesit two-chamber refrigerators are filled with: types of freon and oils, standards and features

Refrigerators Indesit of the two-chamber type are one of the most common on the Russian market. Their reliability largely depends on proper operation refrigerant system, and this, in turn, depends on the type and quality of refrigerant (freon) and compressor oil. If your unit stops freezing, an uncharacteristic noise appears, or the compressor works without stopping, the problem may lie precisely in a freon leak or oil contamination.

Many users mistakenly think that refilling refrigerator is a universal procedure that does not depend on the model. In fact for each generation of Indesit equipment, different types of freons are used (R134a, R600a, R12, etc.), and their volume is strictly regulated by the manufacturer. In addition, the wrong choice compressor oil (mineral, semi-synthetic or synthetic) can lead to system failure after just a few months.

In this article we Let's figure out what refrigerants and oils are used in Indesit two-chamber refrigerators of different years of productionhow to determine the required volume of refilling, and what to pay attention to when replacing it yourself. You will also learn why you cannot mix different types of freons and the dangers of using low-quality oil.

What freons are used in Indesit refrigerators

Manufacturer Indesit at has been changing the types of refrigerants in its refrigerators for decades, following environmental regulations and technical novelties. Today, in two-chamber models there are three main types of freon:

• 🔹 R134a (Tetrafluoroethane) - the most common refrigerant in models released after 2010. It is non-toxic, non-flammable and has a low ozone depletion potential (ODP=0). Suitable for most modern compressors Embraco i Secop.
• 🔹 R600a (Isobutane) is a natural hydrocarbon freon used in environmentally friendly models Indesit since 2015. It has high cooling capacity, but requires caution when filling due to a fire hazard.
• 🔹 R12 (Difluorodichloromethane) is an obsolete refrigerant that can be found in refrigerators manufactured before 2000. Today, its refilling is prohibited due to harm to the ozone layer, so when repairing such models, a complete replacement with a modern analogue (usually R134a) is required.

You can determine which freon is used in your refrigerator by nameplate on the compressor or in the technical passport. If the marking is erased, refer to the year of manufacture:

Important: Freons R134a and R600a are not interchangeable! Filling the system with the wrong refrigerant will lead to improper operation of the compressor, increased wear and even failure. If you are not sure about the type of freon, it is better to contact a specialist with a pressure gauge station to analyze the remaining gas in the system.

Compressor oil: types and compatibility with freons

Oil in the refrigerator Indesit performs two key functions: it lubricates the moving parts of the compressor and dissolves freon for its circulation throughout the system. Wrong choice of oil can lead to:

• 🔥 Overheating of the compressor due to insufficient lubrication;
• 🧊 Blockage of the capillary tube due to sedimentation;
• ⚡ Breakdown of motor windings when using oil with low dielectric strength.

For refrigerators Indesit three types of oils are used:

1. Mineral (paraffin-based) - suitable for freon R12 (outdated models) and some compressors s R134a. Marking: Mineral Oil or MO.
2. Semi-synthetic (POE) - universal oils for R134a and R600a. Designated as POE Oil or Polyol Ester.
3. Synthetic (PAG) - used in modern models with R600a highly efficient compressors. Marking: PAG Oil.

Compatibility of oils and freons for Indesit:

⚠️ Attention: When replacing freon with R12 on R134a be sure to flush the system and replace the oil with semi-synthetic! Mineral oil is not compatible with R134a and will cause the compressor to seize.

How to determine the volume of freon filling

The amount of freon required to refill the refrigerator Indesitdepends on:

• 📏 Pipeline lengths (capillary tubes, condenser, evaporator);
• 🔄 Compressor type (power and models);
• 🧊 Volume chambers (single-chamber vs two-chamber models).

Standard charging rates for two-chamber refrigerators Indesit:

The exact volume can be found:

1. On compressor nameplate (usually the mass of freon is indicated in grams);
2. B technical data sheet refrigerator (section "Refrigerant");
3. By labeling models in the database Indesit (for example, through service catalogs).

⚠️ Attention: An excess of freon is just as harmful as its deficiency! When refueling "by eye" you risk getting:

• 🔥 Overheating of the compressor (excess freon increases the pressure in the system);
• ❄️ Insufficient cooling (undercharging leads to weak circulation).

Step-by-step instructions for refilling the Indesit refrigerator

If you decide to refill the refrigerator yourself, follow this algorithm. For work you will need: gauge station, vacuum pump, freon cylinder, wrenches and a leak detector.

Step 1. Leak diagnostics

• 🔍 Inspect places for soldering tubes (especially in the area of the compressor and evaporator).
• 💨 Use leak detector or soap solution to detect microcracks.
• 🔧 Eliminate the leak by soldering or replacing the damaged area.

Step 2. Evacuate the system

Connect the vacuum pump to the service pipe and pump out the air into flow 15–20 minutes. This will remove moisture and remnants of old freon. The pressure in the system should drop to -1 bar.

Step 3. Refilling freon

1. Connect the freon cylinder to the pressure gauge station.
2. Open the valve and fill gas in portions of 10–15 gramscontrolling the pressure.
3. For R134a working pressure discharge: 10–12 bar.
4. For R600a: 4–6 bar (isobutane operates at lower pressure!).

Step 4. Checking operation

After refueling, turn on the refrigerator and check:

• ⏱️ Compressor operating time (should be cyclical, not constant);
• 🌡️ Temperature in the chambers (optimally: in the refrigerator, in the freezer); data-i="200">If the temperature does not drop, check: 1) The tightness of the system (reuse the leak detector); 2) Freon pressure (possibly underfilled); 3) The operation of the thermostat (if it malfunctions, it can block the start of the compressor). +4°C in the refrigerator, -18°C in the freezer);
• 🔊 Noise level (no extraneous sounds).

What to do if after refueling the refrigerator does not freeze?

If the temperature does not drop, check: 1) The tightness of the system (reuse the leak detector); 2) Freon pressure (possibly underfilled); 3) The operation of the thermostat (if it malfunctions, it can block the start of the compressor).

Frequent errors during refueling and their consequences

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here are the most common of them:

• 🔄 Mixing freons —for example, adding R134a to the system where it was R600a. This leads to a chemical reaction, blockage of the capillary and failure of the compressor.
• 🛢️ Use of the wrong oil —for example, mineral instead of synthetic. Consequences: overheating, piston jamming, current leakage to the housing.
• 💨 Incomplete evacuation - if there is moisture left in the system, it will freeze in the capillary tube and block the circulation of freon.
• ⚖️ Incorrect filling volume —an excess of freon leads to increased load on the compressor, and a deficiency leads to poor cooling.

⚠️ Attention: If after refilling the refrigerator runs without stopping, but does not freeze, most likely there is air left in the system. It is necessary to repeat the vacuuming and filling!

Another typical problem is contamination of the system after a leak. If the freon leaked due to corrosion of the tubes, rust particles could remain inside. In this case, before refueling you need to:

1. Rinse the system special solvent (for example, R141b);
2. Replace filter drier;
3. Blow out the tubes nitrogen to remove residual solvent.

When refilling does not help: signs of other breakdowns

Sometimes users mistake other faults for a freon leak. Before refilling the refrigerator, check:

• 🔌 Thermostat - if it is faulty, the compressor may not turn on or run without stopping. short circuit.
• ❄️ Evaporator —if it is covered with ice, the problem is in the system No Frost (the heating element or defrost timer is faulty).
• 🔊 Fan —in models c No Frost its breakdown leads to a lack of cold air circulation.
• 🔋 Starting relay - if the compressor hums but does not start, the relay or motor windings may have burned out.

⚠️ Attention: If the refrigerator Indesit with the system No Frost stops freezing, but the compressor is working, most likely the problem is defrost heater or fusefilling with freon will not help here!

To accurately diagnose a breakdown, pay attention to error code (if your model is equipped with a display). data-i="249">error code

• F01 - problem with the temperature sensor;
• F04 - malfunction of the fan motor;
• F07 - malfunction of the compressor.

Where to buy freon and oil for Indesit

You should purchase refrigerant and oil only from trusted suppliers. Here's what you need to know:

• 🏪 Freon R134a and R600a sold in cylinders at 13.6 kg (for workshops) or 0.5–1 kg (for one-time refilling: 800–1200 rub. (for 2026).
• 🛒 POE/PAG oil packaged in cans 1 l. Popular brands: Emkarate, Bitzer, Shell. Cost: 1500–2500 rub./l.
• ⚠️ Be careful with counterfeits! Poor quality freon may contain impurities that will destroy the compressor. Check the certificates with the seller.

Where to buy:

⚠️ Attention: When purchasing freon R600a check with the seller whether the cylinder is certified for domestic use. Isobutane is fire hazardous, and its transportation is subject to strict control.

FAQ: Answers to frequently asked questions

Is it possible to refill an Indesit refrigerator 2005 with freon R600a instead of R134a?

No, this is impossible without completely replacing the compressor and oil. R134a and R600a require different types of oils and have different operating pressures. In addition, the system must be adapted for isobutane (for example, the capillary tube may not be suitable). suitable for the diameter). data-i="300">2500–3500 rub. R134a with semi-synthetic oil POE.

How much does it cost to refill an Indesit refrigerator at a service center?

The cost depends on the type of freon and the complexity of the work:

• Refueling R134a: 2500–3500 rub.;
• Refueling R600a: 3000–4500 rub. (due to increased safety requirements);
• Oil change + vacuum: +1000–1500 rub.;
• Leak elimination (soldering tubes): 1500–3000 rub..

Total average bill: 4000–8000 rub..

What happens if you pour freon into the refrigerator?

An excess of freon leads to:

• Increased pressure in the condenser → overheating of the compressor;
• Deterioration of heat transfer → poor cooling;
• Risk of water hammer in the compressor → breakage of the piston group.

If you overfilled freon, you must bleed off the excess through the service pipe, monitoring the pressure with a pressure gauge.

How often do you need to refuel an Indesit refrigerator?

Under normal conditions, freon leaks extremely slowly (for example, through microcracks in soldering). Average time between refills:

• For new models (after 2015): 10–15 years;
• For refrigerators 2000–2010: 5–10 years;
• For equipment older than 2000 years: 3–7 years (due to wear of tubes).

If the leak occurred earlier, look for mechanical damage (for example, after transporting the refrigerator).

Is it possible to fill a refrigerator with car freon from an air conditioner?

Absolutely not! Automotive air conditioners are used R134a, but:

• They add special UV dyes to detect leaks that can clog the capillary tube of the refrigerator;
• Automotive freon often contains impuritiesimpurities that are unacceptable for household appliances;
• The volume of the cylinder for car air conditioners (300–500 g) may not be enough to fully refill the refrigerator.
