Amount of freon in the Indesit No Frost refrigerator: table by model and checking instructions

Have you noticed that the refrigerator Indesit No Frost has become worse at freezing, and the compressor is running non-stop? One possible reason is a freon leak. But before you call a technician or try to refuel the system yourself, you need to know exactly how much refrigerant is required for your model. In this article, we have collected current data on the volume of freon in refrigerators Indesit with a system No Frost, and also explained how to check its quantity and avoid typical mistakes when refilling.

It is important to understand: the amount of freon depends not only on the brand, but also on refrigerator models, its dimensions and type of compressor. For example, in compact single-chamber models, the volume of refrigerant may not exceed 50 grams, while in large two-chamber units with No Frost - up to 150 grams or more. We have prepared a detailed table with a breakdown of popular series Indesit, and also explained how to independently determine the required volume if your model is not on the list.

If you are planning a DIY repair, please note: working with freon requires special equipment and skills. Incorrect charging can lead to compressor failure or even an explosion due to excess pressure in the system. In the article you will find not only technical data, but also risk warnings, as well as tips on how to minimize repair costs.

Why is it important to know the exact amount of freon in the refrigerator

Freon (refrigerant) - This is the “blood” of the refrigeration system. Its deficiency or excess is equally harmful to technology. This is why accuracy is critical here:

• 🔧 Underfilling leads to overheating of the compressor. It starts working without stopping, trying to compensate for the lack of cold, which reduces the service life of the unit by 2-3 times.
• ❄️ Excess freon creates excess pressure in the circuit. This can lead to ruptured tubes or valve failure, and in rare cases, to an explosion (especially if an old-style flammable refrigerant is used).
• 💰 Saving on repairs. Knowing the exact volume, you can buy freon in the right quantity without overpaying for extra grams (the price for 1 kg can reach 3-5 thousand rubles).
• ⚖️ Fault diagnosis. If after refueling the refrigerator still does not freeze, the problem may not be a leak, but a clogged capillary tube or a broken sensor.

Many technicians fill the system “by eye”, focusing on average values. However, for models Indesit No Frost this is fraught with errors: for example, in refrigerators of the series DF 5200 the volume of freon may differ from DF 4180 by 30–40 grams. If you are not sure of the accuracy, it is better to use the weight filling method (we will talk about this below).

Table: amount of freon in Indesit No Frost refrigerators by model

Below is the data for popular series of refrigerators Indesit with system No Frost. Please note: the values ​​​​are indicated for refrigerant R-134a (the most common option in modern models). If your refrigerator uses R-600a (isobutane), the volume may differ by 10–15% downward.

If your model is not in the table, the volume Freon can be identified by nameplate (metal plate on the back wall of the refrigerator). Look for the line Refrigerant Charge or Refrigerant —the exact amount in grams is indicated there. If the nameplate is worn out or missing, use the formula:

Freon volume (g) ≈ fridge compartment volume (l) × 0.8 + 20–30 g

For example, for a refrigerator Indesit with a volume of 300 liters: 300 × 0.8 + 25 ≈ 265 g. However, this method gives an approximate figure. For accurate charging, it is better to refer to the technical documentation or use the weight method (about it in the next section).

How to check the amount of freon in a refrigerator without equipment

You can suspect a freon leak by indirect signs, even without a pressure gauge or leak detector. Here are the main symptoms:

• ❄️ The freezer compartment does not freeze, and the refrigerator barely cools. In this case, the compressor works constantly.
• 🔊 Unusual sounds: gurgling, hissing or whistling from the back of the refrigerator (a sign of leakage through microcracks).
• 🌡️ Condensation on the rear wall (in models with an open condenser) or icing of tubes.
• 🕒 Long compressor downtime between cycles (more than 30 minutes) at high temperatures in the chambers.

For more accurate diagnostics, perform the following steps:

1. Unplug the refrigerator and defrost it for 12-24 hours.
2. Turn it on again and listen: if the compressor starts, but after 5-10 minutes it turns off (and the chambers do not cool), most likely there is not enough freon.
3. Check the condenser temperature (grid on the back wall): If it is barely warm, this is a sign of low pressure in the system.

Check the temperature in the chambers|Inspect the back wall for oil stains (a sign of leakage)|Listen for unusual sounds|Check the compressor operation (should turn on every 15-20 minutes)-->

If you have confirmed leak, do not rush to refill the system. First you need find and eliminate the leak location otherwise the freon will leak out again. To do this, use a leak detector or a soap solution (at home). Coat all pipe connections with soap foam: if there is a leak, bubbles will appear.

⚠️ Attention: Refrigerant R-600a is heavier than air and can accumulate in the lower part of the room. If there is a large leak there is a risk of explosion! Ventilate the room and do not turn on electrical appliances until the gas has completely evaporated.

How to fill freon into the Indesit No Frost refrigerator: step-by-step instructions

If you decide to fill the refrigerator yourself, you will need:

• 🔧 Vacuum pump (for pumping air from the system).
• 🧪 Cylinder with freon (type R-134a or R-600a, depending on the model).
• ⚖️ Scales (for accurate dosing of refrigerant).
• 🔌 Gauge manifold (for pressure control).
• 🔨 Keys for service ports (usually included with the manifold).

The charging process includes several steps:

1. Pumping out old freon. Connect the manifold to the service port (usually located on the compressor) and bleed off the remaining refrigerant. Be careful: freon is under pressure!
2. Evacuating the system. Connect the vacuum pump and pump out the air for 15–20 minutes. This will remove moisture and prevent the formation of ice jams.
3. Refilling with new freon. Put the cylinder on the scale, zero it and slowly open the valve, controlling the weight. For example, for Indesit DF 4180 you need to fill exactly 95 grams.
4. Checking the pressure. After filling, the pressure in the system should be about 0.5–0.7 bar (for R-134a). If it is higher, there is too much freon.

After refueling, turn on the refrigerator and check its operation. If after 2–3 hours the temperature in the chambers has not dropped to normal, two problems are possible:

• 🔍 Leakage of the system —freon leaks out again.
• 🔧 Clogged capillary tubes —purge or replacement is required.

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

If refueling was successful, but the refrigerator does not cool, check:

1. Thermostat —it may not be sending a signal to the compressor.

2. Start relay —if it burns out, the compressor will not start.

3. Temperature sensor —in electronically controlled models it may give incorrect readings.

In 70% of cases the problem lies not in freon, but in electronics!

⚠️ Attention: If you have never worked with refrigeration equipment, it is better to entrust the filling to a professional. An error in the dosage of freon or a leak in the seal can lead to compressor breakdown (replacement cost - from 8 to 15 thousand rubles).

What is the difference between refilling freon in No Frost from drip refrigerators

The system No Frost has several key features that affect the refilling process:

1. An additional fan. In models with No Frost freon circulates not only along the main circuit, but also through the evaporator, blown by a fan. This means that the pressure in the system is higherthan in drip refrigerators.
2. Larger volume of refrigerant. Due to the presence of additional tubes and an evaporator in the systems No Frost is required for 15–25% more freon than in drip analogues of the same volume.
3. Sensitivity to moisture. If all moisture is not removed during evacuation, it will freeze on the evaporator and the system will stop working. In drip refrigerators this is less critical.

Another nuance: in No Frost refrigerant is used more often R-134a, whereas in older drip models you can find R-12 (banned for use since 2020) or R-600a. Never mix different types of freon - this will lead to a chemical reaction and failure of the system!

If you are refilling the refrigerator Indesit No Frost for the first time, please note:

• 🕒 Evacuation time must be at least 20 minutes (10-15 is enough for drip ones).
• 🌡️ Filling pressure for R-134a — 0.5–0.7 bar, for R-600a — 0.3–0.5 bar.
• 🔧 Checking the fan. After refueling, make sure that it rotates freely - sometimes excess freon leads to icing of the blades.

How much does it cost to refill freon in an Indesit refrigerator: prices 2026

The cost of refilling depends on the type refrigerant, operating complexity and region. Below is an indicative price list for Moscow and the regions:

You can save if:

• 🛒 Buy freon yourself (in stores for car air conditioners it is cheaper).
• 🔧 Fix the leak yourself (if it is in an accessible place, for example, at the place where pipes are soldered).
• 📞 Call a specialist for a promotion (many services offer discounts on diagnostics).

⚠️ Attention: Prices may vary depending on the dollar exchange rate and the availability of spare parts. Check current prices at service centers in your city.

Common mistakes when refilling freon and how to avoid them

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

• ❌ Incomplete vacuuming. If moisture remains in the system, it will freeze in the capillary tube and the refrigerator will stop freezing. Solution: Vacuum for at least 20 minutes, use a high-quality pump.
• ❌ Refilling freon. An excess of refrigerant is as harmful as its deficiency. Solution: Use scales and refill strictly according to the norm.
• ❌ Using the wrong freon. For example, charging R-600a instead of R-134a will lead to increased pressure and compressor breakdown. Solution: Check the type of refrigerant for nameplate.
• ❌ Ignoring the leak. If the cause of the leak is not eliminated, the freon will leak out again. Solution: Find and seal the leak before refueling.
• ❌ Seal failure during connection. Poorly tightened fittings or cracked hoses will lead to repeated leakage. Solution: Use new O-rings and check the connections with a soapy solution.

Another typical problem is clogging of the capillary tube. If after refueling the refrigerator does not freeze, but the compressor works, the tube may be clogged with oil decomposition products or moisture. In this case, you will need to:

1. Cut off the capillary tube at the filter drier.
2. Blow it with nitrogen under a pressure of 10–15 bar.
3. If blowing does not help, replace the tube or filter.

If you are not sure of the cause of the malfunction, do not take risks - contact service. For example, in Moscow, the companies "RemBytTech" and "Holod Service" provide a guarantee for refilling freon for up to 1 year.

FAQ: Answers to frequently asked questions about freon in Indesit refrigerators

Is it possible to refill an Indesit No Frost refrigerator with R-600a freon if it was previously R-134a?

No, this is strictly prohibited! Refrigerants R-134a and R-600a have different chemical properties and pressure. Refilling with unsuitable freon will lead to:

• Increased load on the compressor (it will burn out in 1-2 months).
• Formation of ice plugs in the capillary tube.
• Risk of explosion (R-600a flammable!).

If you need to switch to another type of freon, you will need to completely replace the compressor and flush the system.

How often should you check the freon level in the refrigerator?

Under normal conditions, freon does not evaporate - the system is sealed. You need to check its level only if there are signs of a leak:

• The refrigerator does not freeze, but the compressor is working.
• Oil stains have appeared on the back wall.
• You can hear hissing or gurgling.

If the refrigerator is operating stably, additional checks not required. The average service life of the system without leaks is 10–15 years.

What to do if after refueling the refrigerator works, but is very noisy?

Noise after refueling can be caused by:

• Excess freon - the compressor is working under increased load.
• Air lock in the system (if evacuation was insufficient).
• Fan malfunction (in models No Frost).

Solution: Turn off the refrigerator for 1-2 hours, then turn it on again. If the noise does not disappear, you need to bleed off the excess freon or check the fan.

Is it possible to charge freon without a vacuum pump?

Technically it is possible, but this is fraught with consequences:

• It will remain in the system moisture, which will freeze and block the capillary tube.
• The air in the circuit will increase the pressure and load on the compressor.
• The service life of the refrigerator will be reduced by 2-3 times.

If there is no vacuum pump, it is better to contact a service center. (in some cities it costs 500–1,000 ₽ per day).

How much does a cylinder of R-134a freon cost and where to buy it?

Freon prices R-134a in 2026:

• Cylinder 13.6 kg — 8,000–12,000 ₽ (for service centers).
• Cylinder 0.5 kg — 1,500–2,500 ₽ (for household use).
• Refill 100 g — 800–1,200 ₽ (in services).

You can buy freon:

• In auto parts stores (used for air conditioners).
• In specialized online stores (for example, "Holod-Master", "Freon-Shop").
• From refrigerator repair specialists (sometimes they sell small batches).
