Disassembling the Stinol No Frost refrigerator: detailed instructions with photos and tips

Disassembling a refrigerator Stinol with a system No Frost on your own is a task that requires not only technical skill, but also an understanding of the structure of the unit. Unlike drip models, where the main problem is with the drainage system, here the fan, evaporator and duct system play a key role. If you encounter a malfunction (for example, the refrigerator does not freeze, but the light is on, or ice has appeared on the back wall), disassembly can help diagnose the problem without calling a technician.

In this article we will look in detail at how to dismantle the main components Stinol No Frost, what tools will be needed, and what to pay attention to in order not to damage the system. It is important to understand: No Frost - this is not just “without defrosting”, but a complex air circulation system, and improper disassembly can lead to freon leakage or compressor failure. Therefore, if you are not confident in your abilities, it is better to contact a specialist.

Before you begin, please note: models Stinol (for example, STN 165, STN 185, STN 200) may have design differences. In the article we focus on a standard diagram, but always check with instructions for your model. Also remember that disassembling the refrigerator will void the manufacturer's warrantyif it is still valid.

1. Preparing for disassembly: tools and safety measures

Before disassembling the refrigerator, you need to prepare your work area and tools. This will minimize the risk of damage to equipment and simplify the process.

Required set of tools:

• 🔧 Phillips and flathead screwdrivers (preferably with a magnetic tip for small screws).
• 🔨 A set of socket wrenches or heads (most often you need sizes 8, 10 mm).
• 📸 Camera or smartphone for recording the location of parts before dismantling.
• 🧲 Magnet for collecting small metal parts (screws, washers).
• 🧤 Rubber gloves (freon and oil from the compressor can be irritating skin).

Safety measures:

• ⚡ Unplug the refrigerator at least 10–12 hours before disassembling. This is necessary for the capacitor to discharge (in some models it can retain a charge for up to a day!).
• 🚫 Do not use sharp objects (knives, chisels) to dismantle plastic panels - this will lead to cracks.
• 🌡️ Work well in a ventilated area: if the freon circulation system is damaged, a gas leak may occur.

⚠️ Attention: If your refrigerator Stinol was manufactured before 2010, it may use freon R-12 or R-22, which are more toxic than modern analogs. If there is a leak, immediately ventilate the room and avoid inhaling fumes.

Also prepare containers for sorting screws and small parts - this will save time during reassembly. For example, you can use plastic containers or bags with stickers ("door screws", "evaporator fasteners", etc.).

2. Dismantling the internal panels of the refrigerator compartment

Let's start by disassembling the refrigerator compartment, since this is where ice most often accumulates and problems with ventilation arise. In models Stinol No Frost internal panels are secured with latches and screws, so you need to act carefully.

Procedure:

1. Remove all shelves, drawers and door compartments. They are mounted on guides or latches - pull them towards you with a little force.
2. Unscrew the screws that secure the top panel (usually they are hidden under the plugs). In models STN 165/185 there may be 2-4 pieces.
3. Remove the top cover by pulling it up and slightly towards you. Under it you will see the fan and air ducts.
4. Disconnect the fan power connectors (usually this is a chip with 2-3 contacts). Remember or take a photo of their location!

After dismantling the top panel, you will gain access to evaporator —the main element of the system No Frost. Normally, it should be clean and free of ice. If you see a thick layer of ice, this indicates a malfunction Defrost heating element or temperature sensor.

⚠️ Attention: If, when dismantling the panel, you find that the wires are connected to the control board via soldering (and not connectors), do not try to unsolder them without experience! It’s better to take a photo of the diagram and contact a specialist.

3. Disassembling the freezer compartment and accessing the compressor

The freezer compartment in refrigerators Stinol No Frost is more difficult to disassemble, since the main cooling elements are located here: a compressor, a condenser and a capillary tube. If the problem is related to insufficient cooling, most likely, the malfunction lies here.

How to remove the rear panel of the freezer:

• 🔧 Unscrew the screws securing the rear wall (usually 4-6 around the perimeter).
• 🧊 Carefully remove the panel, pulling it towards you. Be careful: there may be freon tubes soldered behind it!
• 🔍 Inspect the compressor for oil leaks or corrosion. Normally, it should be dry, free of rust.
• 📏 Check the integrity of the capillary tube (thin copper tube running from the compressor to the evaporator). It should not be pinched or damaged.

If you suspect a freon leak, pay attention to the following signs:

• The compressor runs non-stop, but there is no cold.
• Oil stains are visible on the tubes or at the soldering point (freon circulates along with oil).
• When you turn on the refrigerator, you hear a hissing sound (gas leak).

It is impossible to eliminate a freon leak on your own - this requires special equipment (vacuum pump, freon cylinder) and a certificate. However, you can visually inspect the system for damage and decide to call a technician.

What to do if the compressor does not start?

If the compressor does not hum and does not heat up, the problem may be:

1. Start relay (ring the coil, resistance ~20–50 Ohms).

2. Thermostat (close the contacts directly - if the compressor starts, the sensor is faulty).

3. Control board (check the fuses on the board, they often blow out during power surges).

Do not turn on the refrigerator with a faulty relay - this can lead to an interturn short circuit of the compressor windings!

4. Diagnostics and cleaning of the No Frost system

One ​​of the most common problems in refrigerators Stinol No Frost is a clogged air duct or faulty fan. This leads to uneven cooling, frost on the back wall and increased energy consumption. Let's look at how to diagnose and fix these problems.

Cleaning the fan and air ducts:

1. Disconnect the fan power connector (usually located behind the top panel of the refrigerator).
2. Remove the fan by unscrewing 2-3 screws. Clean the blades from dust and ice using a soft brush.
3. Blow out the air ducts with a vacuum cleaner (use a nozzle with a narrow nozzle). They often accumulate dust and crumbs, blocking the air flow.
4. Check that the fan rotates freely. If it touches the ice or the body, the problem may be in deformed blades.

Checking the defrost heating element:

The heating element is responsible for periodically defrosting the evaporator. If it doesn't work, ice will build up, blocking air circulation. To check the heating element:

• 🔌 Disconnect the wires from the heating element (usually these are two contacts with terminals).
• 📊 Measure the resistance with a multimeter. Normally, it should be within 30–100 Ohm. If the device shows a break (OL), the heating element has burned out.
• 🔍 Inspect the heating element visually: blackening or swelling of the body indicates a malfunction.

If the heating element is working, but there is ice still occurs, the problem may be in defrost timer or temperature sensor. These elements are checked by replacing them with known working ones or checking the continuity of the circuit.

5. Typical mistakes during disassembly and how to avoid them

Even experienced craftsmen sometimes make mistakes when disassembling refrigerators Stinol No Frost. Here are the most common of them and ways to prevent them:

Another common mistake is ignoring the check door seal. Over time, the rubber loses its elasticity, and the refrigerator begins to work harder, trying to compensate for the influx of warm air. To check the seal:

• 📏 Insert a sheet of paper between the door and the body.
• 🚪 Close the door and try to pull out the sheet.
• ✅ If the paper is held tightly - The seal is OK. If it comes out easily, a replacement is needed.

⚠️ Attention: If after disassembling the refrigerator begins to work louder, check whether the fan is touching the case or the ice crust. Also, noise may occur due to loose compressor mounting (the bolts need to be tightened).

6. Reassembly: procedure and testing

Assembling the refrigerator Stinol No Frost should be done in the reverse order, but taking into account several nuances. The main rule: all connectors and fasteners must be fixed as tightly as before disassembly.

Assembly order:

1. Install the evaporator and secure it with screws. Make sure that it is level, without distortions.
2. Connect the wires to the fan and defrost heating element. Check whether the wires are pinched by the housing.
3. Secure the top panel of the refrigerator compartment. Make sure the latches are in place.
4. Install the shelves and drawers. Check whether they interfere with the closing of the door.
5. Connect the refrigerator to the network and run it in test mode (without food).

Testing after assembly:

• 🌡️ Check whether the compressor turns on (should hum 5-10 minutes after connection).
• ❄️ Make sure that the fan is rotating (you can listen or gently touch the air duct - cold air should flow).
• 🕒 Let the refrigerator work for 2-3 hours, then check the temperature in the chambers (normal: +4…+6°C v refrigeration, -18°C in the freezer).

If after assembly the refrigerator does not freeze or works intermittently, possible reasons:

• 🔌 Unconnected connector (check all connections).
• 🧊 Forgot to remove the shipping bolts from the compressor (relevant if the refrigerator was transported).
• 🔧 The thermostat is installed incorrectly (must be tightly fixed in place).

If all checks are passed, but the problem remains, perhaps the malfunction lies in control board or compressor. In this case, you cannot do without a specialist diagnosis.

7. When disassembly does not help: cases for calling a technician

Not all refrigerator malfunctions Stinol No Frost can be fixed independently. There are problems that require professional equipment and knowledge. Here are the cases when it is better to call a specialist:

• 🔥 Freon leak (signs: the compressor runs non-stop, but does not freeze; there are oil stains on the tubes).
• ⚡ Electrical problems (short circuit, burnt-out control board, faulty relay).
• 🛠️ Replacement of the compressor (requires soldering of tubes, evacuation of the system and charging with freon).
• 🧊 Damage to the evaporator (for example, corrosion or mechanical deformation).
• 📱 Errors on the electronic display (if the refrigerator is equipped with a display and shows fault codes).

It is also worth contacting a specialist if you:

• You are not sure of the cause of the malfunction (for example, the refrigerator sometimes works, sometimes it doesn’t).
• You have found oil leaks from the compressor.
• You hear uncharacteristic sounds (knocking, grinding) during operation.

⚠️ Attention: If your refrigerator Stinol is still under warranty, disassembling it yourself will void it. In this case, be sure to contact the service center.

The cost of repairs from professionals depends on the complexity of the malfunction. For example:

• Replacement of defrost heating element: ~1500–2500 rub.
• Repair of freon leak: ~3000–5000 rub. (including refilling).
• Replacement of the compressor: ~4000–7000 rubles.

FAQ: Frequently asked questions about disassembling the Stinol No Frost refrigerator

Is it possible to disassemble the refrigerator without disconnecting it from the network?

No! This is extremely dangerous. The capacitor can retain its charge even after being turned off, and accidentally shorting the wires will result in an electric shock. Always unplug the refrigerator from the outlet 10–12 hours before starting work.

How can you tell if there is a freon leak in the refrigerator?

Main signs:

• The compressor works constantly, but there is no cold.
• Oil stains are visible on the tubes or at the soldering point.
• When turned on, a hissing sound is heard (gas leak).
• The condenser (grid on the back wall) remains cold.

You cannot fix the leak yourself - you need a technician with equipment for vacuuming and filling.

What to do if after disassembling the refrigerator begins to make noise?

Possible causes and solutions:

• The fan touches the ice or housing → Defrost the refrigerator and check the fastening fan.
• The compressor fastening is loose → Tighten the bolts on the compressor (but do not overtighten!).
• The tubes vibrate and knock on the body → Secure them with plastic ties.

If the noise does not disappear, check the fan bearings - they may need to be lubricated or replaced.

How long does it take to defrost the refrigerator before disassembling?

Minimum 12 hours, or better yet, a day. This will ensure that all the ice melts and you won't damage the plastic parts when dismantling. You can speed up the process by placing a container of warm water (but not boiling water!) in the chamber.

Is it possible to clean the No Frost system without disassembling?

Partially - yes. You can:

• Blow the air ducts with a vacuum cleaner through the holes in the rear wall.
• Clean the fan with a soft brush (if it is accessible without removing the panel).
• Carry out a complete defrost (sometimes this solves the problem with ice).

However, for deep cleaning of the evaporator and checking the heating element, disassembly is still necessary.
