The situation when Stinol refrigerator stops cooling food correctly or makes strange sounds is familiar to many owners of this equipment. Often the reason lies in a minor malfunction, which you can fix yourself if you have access to the internal components of the unit. However, before you grab the tools, you need to clearly understand that disassembling the refrigerator is a process that requires accuracy and knowledge of the sequence of actions.
Unlike modern models, where access to units may be limited by the complex design of the case, Soviet and post-Soviet Stinol refrigerators designed with maintainability in mind. The main difficulty is to properly remove the decorative panels and get to evaporator or compressorwithout damaging the fragile plastic and fasteners. In this article we will look in detail at the algorithm of actions for the safe dismantling of the main components.
Before starting any work, it is absolutely necessary to de-energize the device. Unplug the power cord from the outlet and wait at least 30 minutesto the refrigerant and oil in the system have come into equilibrium, and the pressure has equalized. Ignoring this rule may result in injury or damage to the cooling system if the tubes are accidentally punctured.
Necessary tools and workplace preparation
Quality disassembling the Stinol refrigerator is impossible without proper selected tools. You will need not only a standard set of screwdrivers, but also some specific tools that will help avoid damaging the plastic. Prepare a container for water in advance, since during dismantling drop catcher or the evaporator, condensation may leak out.
Particular attention should be paid to lighting the work area. Refrigerator interiors are often dark, and poor light can cause you to miss a hidden screw or break a latch. Use a headlamp or portable lamp to see all the nuances of the design.
- 🛠️ A set of Phillips and flathead screwdrivers of different sizes for loosening case screws and shelf fastenings.
- 🔧 Pliers or pliers for removing clamps and working with wires.
- 🔦 Powerful flashlight for illuminating internal niches and hard-to-reach places.
- 🧤 Work gloves to protect your hands from sharp metal edges and dirt.
⚠️ Attention: Do not use sharp metal objects (knives, awls) to pry up plastic panels. This is guaranteed to lead to scratches and chips, which will subsequently be impossible to hide.
☑️ Preparation for disassembly
Dismantling the top panel and removing the ceiling light
The process of how to disassemble Stinol refrigeratorusually starts from the top of the refrigerator compartment. This is where the lampshade is located and where the top cover fasteners are often hidden. In models with an upper freezer or two-chamber units, the sequence may differ slightly, but the general principle remains the same.
First you need to dismantle the lampshade. Depending on the model Stinol, it may be held on by latches or screws. If you see screws, carefully remove them. If there are no screws, the lampshade needs to be slightly pryed off with a flat screwdriver, but this should be done extremely carefully, since the plastic becomes brittle over time.
After removing the lampshade, access to the top panel will open. It can be secured with screws around the perimeter or have hidden latches. In some modifications, you first need to remove the decorative trim to get to the main fastener. Top panel often serves as a support for other elements, so its removal is a key step.
Fastening features in different models
In some Stinol models, the top panel is fixed screws that are hidden under plastic plugs. The plugs can be easily removed with a fingernail or a thin needle. Do not try to tear off the panel by force if the screws are not unscrewed - this will lead to breakage of the fasteners.
If you are planning to replace thermostat or sensors, access to which is often located in the upper part, this step is mandatory. Make sure that all wires going to the ceiling are disconnected or have sufficient length to move the panel aside.
Removing the back wall and accessing the evaporator
The most time-consuming part of the repair is often removing the back wall of the refrigerator compartment. It is behind this that hides evaporator the main heat exchange element of the No Frost or drip defrosting system. In models Stinol this panel can be screwed with many screws or held on by plastic clips.
Before unscrewing the screws, be sure to remove all shelves and drawers so that they do not interfere with work. Then carefully inspect the perimeter of the back wall. Sometimes the lower screws are hidden under decorative plugs or located at the bottom of the niche. Use a flashlight for a thorough inspection.
| Mounting type | Location | Tool | Nuances |
|---|---|---|---|
| Screws around the perimeter | 4 corner and middle of the sides | Phillips screwdriver | Can be hidden with plugs |
| Plastic clips | Across the entire plane | Plastic spatula | Require careful snapping |
| Combined | Screws + clips | Screwdriver + spatula | First unscrew the screws, then remove |
After removing the back wall, access to evaporator and the defrost heating element becomes available. It is important to be extremely careful here: aluminum evaporator tubes are very soft and easily damaged. Any scratch or puncture will lead to a freon leak and the need for expensive professional repairs with refilling.
⚠️ Attention: If you see frozen ice on the evaporator, do not try to chip it with a knife or other sharp tool. Wait for complete defrosting or use a hairdryer at minimum temperature, directing the air flow carefully.
Disassembling the freezer and the No Frost system
In refrigerators Stinol with the system No Frost disassembling the freezer has its own characteristics. It is important here not to damage the air duct system and circulation fan. The process begins by removing all drawers and runners.
The back wall of the freezer is usually removed in the same way as the refrigerator compartment, but there may be more screws. Below it there is fan an additional defrosting heating element. If your refrigerator has stopped freezing, but the compressor is working, the problem often lies in these elements.
- ❄️ Remove all plastic drawers and shelves of the freezer.
- 🔩 Unscrew all visible screws on the back and sides panels.
- 🌬️ Carefully disconnect the wire connectors going to the fan and sensors.
Pay special attention to the cold air supply channel. It should not be clogged with ice or foreign objects. When disassembling the system No Frost in Stinol it is often discovered that the drainage hole is clogged with dirt, which leads to the formation of an ice plug.
Access to the compressor and start relay
The lower part of the refrigerator, where the compressor is located, also requires periodic access for diagnostics or replacement. In refrigerators Stinol the compressor is usually closed with a metal or plastic casing at the rear of the unit.
To remove the casing, simply unscrew a few screws around the perimeter. After removing the protection, you will see a black compressor cylinder, a condenser grille and a start relay. It is starting relay that often fails, causing the refrigerator to hum without starting the engine.
Replacing the relay is a simple operation: it is removed from the compressor rod and disconnected from the wires. However, before replacing, make sure that this is the cause of the malfunction. Check the contacts for oxidation and integrity of the wires.
⚠️ Attention: When working in the lower part of the refrigerator, watch the copper tubes. They run next to the compressor casing and are very easy to pinch or bend, which will disrupt the circulation of the refrigerant.
Frequent errors when disassembling yourself
Disassembling the Stinol refrigerator, Beginners often make mistakes that can complicate further repairs. One of the most common is the use of excessive force. The plastic in older models becomes brittle, and a sudden movement can break the fastening eye.
Another mistake is ignoring the markings of the wires. Before disconnecting any connectors, especially those in the control box or near the thermostat, it is recommended that you mark them or take photographs. Mixed up wires can lead to a short circuit or improper operation of the automation.
The drainage system is also often forgotten. When removing the interior panels, the drain pan or tube may be accidentally damaged or dislodged. This will cause water from defrosting to flow not into the evaporator, but onto the floor or inside the cabinet.
- 🚫 Using force where there should be careful movement.
- 🚫 Lack of marking of disconnected wires and connectors.
- 🚫 Damage to thermal insulation when handling the panels carelessly.
⚠️ Attention: Technical characteristics and design of refrigerators may vary slightly depending on the year of manufacture and the specific modification. Always check the technical documentation for your model, if available.
FAQ: Frequently Asked Questions
Is it possible to disassemble a Stinol refrigerator without defrosting it?
Theoretically, you can remove the outer panels, but working inside, especially with the evaporator, without defrosting it is extremely dangerous. Ice can crack aluminum tubes, and water can cause electrical short circuits. Complete defrosting is recommended within 24 hours.
Where is the thermostat located in the Stinol refrigerator?
In most models Stinol the thermostat (or temperature sensor in electronic models) is located inside the refrigerator compartment. It can be hidden in a niche under the top panel or behind the back wall, next to the lampshade.
What to do if the plastic latch breaks during disassembly?
If the latch breaks off, do not despair. The panel can be secured with a small amount of silicone sealant or by carefully drilling a hole and using a small wide-head screw. The main thing is to ensure a tight fit of the panel to maintain thermal insulation.
Do you need to pump out freon before disassembling?
No, if you do not plan to solder the pipes or change the compressor. To replace a thermostat, heating element, fan or relay, freon pumping is not required. The system remains sealed until you damage the tubes mechanically.
