Connecting the refrigerator compressor Stinol: instructions with photos and advice from experts

The compressor is the “heart” of the refrigerator Stinol, and its correct connection determines the stable operation of the equipment for years to come. Whether you're replacing a failed unit or installing a new one after a major repair, even a minor wiring error can lead to short circuits, motor overheating, or even a complete appliance failure. In this article we will analyze a step-by-step connection algorithm taking into account the features of popular models Stinol-100, Stinol-103, Stinol-107 and more modern series.

It is important to understand that the procedure requires not only knowledge of electrical circuits, but also an understanding of the principles of operation of the refrigeration circuit. We will tell you how connect the terminals correctlyto check the starting relay and avoid typical mistakes when soldering and testing. And for those who have never worked with freon, we will give a safety checklist to prevent refrigerant leakage.

If your refrigerator Stinol suddenly stops freezing, but the light inside is on and the motor does not start - in 80% of cases the problem is precisely compressor or its circuits. Our instructions will help diagnose the malfunction and make the connection without calling a technician.

1. Preparation: tools and safety precautions

Before you begin, make sure you have everything you need. Lack of even one tool can lead to irreparable errors. For example, using unsuitable solder for soldering tubes is fraught with microcracks and freon leakage a month after repair.

Here minimum setthat you will need:

• 🔧 Set of screwdrivers (Phillips and flat)
• 🔨 Pliers and wire cutters
• 🔥 Blowtorch or gas torch (for copper tubes)
• 🧲 Multimeter (for checking windings compressor)
• 🛠️ Vacuum pump (for pumping air out of the system)
• 🧪 Manometric manifold (for refilling with freon)
• 🔌 Insulating tape and heat-shrinkable tubes

Pay special attention safety precautions:

• 🚨 Work in a well-ventilated area - freon R134a or R600a (in new models Stinol) is not toxic, but can cause suffocation in high concentrations.
• 🧤 Use protective gloves: the compressor heats up to 90°C, and the copper tubes have sharp edges after cutting.
• ⚡ Unplug the refrigerator and discharge the capacitor (if it is in the circuit) - voltage in the circuits can persist for up to 10 minutes!

⚠️ Attention: If your model Stinol uses refrigerant R600a (isobutane), remember that it is extremely explosive if leaked in a closed space. Do not smoke or use open fire near the refrigerator!

2. Compressor diagnostics: how to make sure that it is working

Before connecting a new (or used) compressor, you need to check it. Even an apparently serviceable motor may have turn-to-turn short circuit or a broken winding. For diagnostics, we use a multimeter in resistance measurement mode (Ω).

On the compressor body Stinol there are three terminals (contacts), marked with letters:

• S (Start) - starting winding
• R (Run) - working winding
• C (Common) - general output

Check procedure:

1. Measure the resistance between C and R (working winding): Normal. data-i="103">(depending on the model). 15–40 Ohm (depending on the model).
2. Measure the resistance between C and). S (start winding Normal: 20–50 Ohm.
3. Measure the resistance between R and S. It should be ≈ the sum of R-C + S-C (for example, 30 + 40 = 70 Ohm).
4. Check for absence of short circuit to the housing: one multimeter probe on the metal body of the compressor, the second - alternately on S, R, CThe resistance should tend to ∞.

What to do if the resistance does not match. normal?

If the resistance between R and S is less than the sum R-C + S-C, this indicates an interturn short circuit. Such a compressor must be replaced. If the resistance between any terminal and the housing is not ∞, this is a breakdown to the housing - do not connect this one! motor.

⚠️ Attention: In compressors Stinol older than 2005 (for example Stinol-100) mineral-based oil is often used. In new models (after 2010) - synthetic POE. You cannot mix them - this will lead to jamming of the engine!

3. compressor: step-by-step algorithm

If you are replacing a faulty compressor, you first need to carefully remove the old one. The main task is to prevent moisture or debris from entering the system. Here's how to do it correctly: do not damage the tubes and prevent moisture or debris from entering the system. Here's how to do it right:

Disconnect the refrigerator from the network and discharge it. condenser

Cut the tubes with wire cutters at a distance of 10–15 cm from the compressor

Plug the open ends of the tubes (for example, with electrical tape)

Unscrew the compressor mounting bolts (usually 4 pieces)

Disconnect the starting relay terminals (remember their location!)

-->

Pay special attention biting off the tubesUse only special pipe cutters or sharp wire cutters. If the tube is flattened, it will be difficult to flare it for soldering the new compressor. plug the holes - even microscopic particles of dust or moisture can clog the capillary tube.

The photographs below show a typical compressor Stinol-103 with terminal markings. Please note. on starting relay (black box on top) - it also needs to be checked before installing it on a new motor:

(There could be a photo here, but we will describe the key points in text format.) The starting relay is attached to the compressor using a spring clamp. Underneath it is a positor (thermistor), which is responsible for starting. motor. If the relay is burned out, the compressor will not turn on, even if the motor itself is working.

4. Connecting a new compressor: diagram and nuances

Now we move on to the most important stage - connection First connect the tubes correctly. To do this:

1. Sand the ends of the tubes with sandpaper (remove oxides).
2. Place them on the tubes Union nuts (they come complete with the compressor).
3. Flare the ends of the tubes using rolling (the cone should be smooth, without cracks).
4. Apply to the soldering area flux for copper (for example, F-38N).
5. Solder the tubes with a gas torch using solder POS-61 or POS-40.

After soldering, be sure to purge the system with nitrogen (or dry air) to remove moisture. Then connect vacuum pump for 15-20 minutes to remove air and flux vapor. Only after this can you refill freon.

Now we move on to electrical connectionThe diagram for most models Stinol looks like this:

• 🔌 Terminal C (Common) is connected to neutral wire network (blue or cyan).
• 🔌 Terminal R (Run) is connected to phase wire via a thermostat (usually brown or red).
• 🔌 Terminal S (Start) is connected to phase wire via a starting relay (black or yellow).

In models Stinol with electronic control (for example, Stinol RF-360) the circuit may be different - it uses control module, which supplies signals to the compressor. In this case, follow the markings on the board.

5. Charging with freon: what refrigerant to use

In refrigerators Stinol different types of freon will be used. to incorrect operation (for example, the motor will work without stopping, but the temperature in the chamber will not drop below +10°C).

For refueling you will need:

• 🧪 Freon cylinder (check the label on the compressor - the brand is indicated there).
• 📉 Manometric manifold (blue hose - low pressure, red - high).
• 🔧 Key for the service port (usually 1/4").

Refilling algorithm:

1. Connect the manifold to the service port (it is located on filter drier).
2. Open the cylinder valve and bleed the air from the hose.
3. Start the compressor and slowly open the low pressure valve (blue).
4. Control the pressure: for R134a normal 0.1–0.3 MPa on the suction side.
5. Fill until the condenser tube heats up to 50–60°C.

⚠️ Attention: When filling R600a (isobutane), the cylinder should stand vertically —this freon is charged in the liquid phase! If you turn the cylinder over, gas will enter the system and the compressor will work with overload.

6. errors

After connecting and refueling, turn on the refrigerator and observe its operation at least 2 hours. Errors often do not appear immediately, but after 30–60 minutes. Here's what to pay attention to:

• ❄️ Compressor should start with a characteristic relay click and work in cycles (10-15 minutes of work, 5-10 minutes of rest).
• 🌡️ The temperature in the freezer should drop to -18°C 3–4 hours.
• 🔊 The noise during operation should be uniform, without knocking or vibration.
• 💧 There should be no frost or condensation on the back wall (this is a sign of undercharging of freon).

Typical errors and their consequences:

Critical error: if after refueling the compressor runs for 1-2 minutes and turns off with a loud click, this is a sign that the thermal relay has tripped due to overheating. Immediately turn off the refrigerator and check the resistance of the windings!

7. Connection features in models with No Frost

In refrigerators Stinol with a system No Frost (for example, Stinol NF-440), the compressor connection diagram has nuances:

• 🌀 Additionally installed blowing fan, which is turned on along with compressor.
• ❄️ The evaporator is hidden behind the panel, and to access the tubes you need to remove the internal lining.
• 🔄 Used defrost timer, which periodically turns off the compressor for defrost the evaporator.

When replacing the compressor in these models:

1. Turn off the power and wait for complete defrosting (8-12 hours).
2. Remove the back panel of the freezer to access evaporator.
3. Check the integrity Defrost heating element - if it burns out, the compressor will work with overload.
4. After charging freon, start the refrigerator and check the operation of the fan (it should blow cold air).

In models with No Frost often used two-compressor. diagram (separately for the refrigeration and freezer compartments). In this case, the compressors are connected in parallel, but each has its own starting relay and thermostat.

8. When it is better to call a specialist: signs of complex faults

Not all breakdowns can be fixed on your own. Here are the cases when it is better to contact a professional:

• 🔧 Crack in the cooling circuit (argon gas required). welding).
• 💥 Swelling or blackening of the start relay (a sign of a short circuit in the windings).
• 🧊 Freon leakage in the foamed part of the housing (needs to be drilled and soldered).
• 📉 Malfunction of the electronic module (diagnosis with an oscilloscope is required).

If you are not confident in your abilities, remember: the cost of a technician's visit (1500–3000 rubles) is often lower than the damage from improper repairs. For example, replacing a burnt-out compressor due to a connection error will cost 5000–8000. rubles, plus freon refilling and diagnostics.

However, if you decide to act on your own, here a brief reminder for the final check:

All tubes soldered hermetically, without cracks

The compressor terminals are tightened, there is no sparking

The starting relay is installed correctly (according to the marks)

Freon is charged in the required amount (according to the pressure gauge)

The refrigerator is level (the adjusting feet are calibrated)

-->

FAQ: Frequently asked questions about connecting the compressor Stinol

Is it possible to connect a compressor from another refrigerator (for example, from Atlanta or Indesit)?

Theoretically, yes, but only if they match:

• Freon type (for example, R134a).
• Compressor power (must be no lower than the original).
• Oil type (mineral or synthetic).

However, even if the parameters match, it may be necessary replacement of the capillary tube (its diameter is selected according to the performance of the compressor). In 70% of cases, such a “mix” leads to unstable operation.

How to check if it is working compressor after connection, if freon has not yet been charged?

Can be done short-term start (no more than 1-2 minutes):

1. Connect the compressor to the network via the start relay.
2. Apply power for a short time (for example, through an extension cord with a button).
3. A working compressor should:
• Hum evenly, without knocking.
• Heat up (but not higher than 60–70°C in 1 minute).
• Create pressure on the discharge tube (you can check it with your hand - it should become warm).

⚠️ Do not run the compressor without freon for more than 2 minutes —this will lead to overheating and failure!

What to do if, after replacing the compressor, the refrigerator freezes too much (food freezes)?

This a sign of one of three problems:

1. Recharging freon —you need to bleed off the excess through the service port.
2. Faulty thermostat —check it with a multimeter (at room temperature the contacts should be closed).
3. Stuck valve (in models with No Frost) - replacement is required.

First check the thermostat: turn it off and connect the wires directly. If the compressor starts working in normal mode, the thermostat must be replaced.

Is it possible to solder tubes with a regular soldering iron, or do you need a torch?

Regular soldering iron not suitable! Reasons:

• The copper soldering temperature should be 250–300°C, and the soldering iron does not provide uniform heating.
• Flux for copper requires an open flame to activate.
• The connection soldered with a soldering iron will be fragile and may leak after 1-2 months.

Use gas burner with a narrow flame or blowtorch. For reliability, after soldering, rinse the tubes with nitrogen.

How much does a new compressor cost for Stinol and where to buy it?

Prices depend on the model:

• Stinol-100/103: 3500–5000 rubles (compressor DXM-5 or DXM-6).
• Stinol RF-360: 6000–8500 rubles (compressor Embraco EGX).
• Stinol with No Frost: 7000–12000 rubles (depending on power).

You can buy:

• In specialized spare parts stores (for example, Rembytekhnika, Holod-Service).
• Na Avito or Yule (but check the seller - they often sell used compressors with worn windings).
• At official dealers Stinol (if the refrigerator is under warranty).

Tip: when purchasing, check the compressor with a multimeter (see section 2 of this article).
