Brand refrigerators Pozis are deservedly considered one of the most reliable units on the domestic market, however, even the most durable equipment periodically requires maintenance or replacement of failed components. Self-disassembly of the housing may be required to replace the thermostat, clear a blockage in the drainage system, or check operation compressor. Understanding the design of your device is the first and most important step to successful repair, which will save budget and time waiting for a repairman.
Before taking active steps, you need to realize that modern household appliances are a complex mechanism, where each screw and latch has its own functional purpose. Improper handling of plastic components or power wiring may cause permanent damage. In this article we will consider in detail the algorithm of actions that will allow you to safely dismantle the main components of the refrigerator Pozis without the risk of damaging paint coating or breaking the tightness of the circuit.
It is important to note that the design of refrigerators may vary slightly depending on the year of manufacture and the specific model, be it classic single-chamber version or modern two-door Side-by-Side. However, the general principles of the manufacturer's layout remain similar. Your task is to act consistently, without using excessive physical force where you need to work mounting latches or unscrew the mounting bolts.
Preparation of the workplace and the necessary tools
Any repair begins with the correct organization of space and preparation of tools. You will need a clear area around the refrigerator to be able to walk around it on all sides and place the removed parts. The lighting should be sufficient, since deep in the unit, behind the panels and under the casings, small fasteners are often hidden, which are easy to lose in the twilight.
The set of tools for disassembling refrigerators Pozis is standard, but must be complete. Failure to use the correct screwdriver may result in the screw slots breaking off or the plastic being damaged. It is recommended to prepare everything you need in advance so as not to interrupt the work process.
- 🛠️ A set of Phillips and flat-head screwdrivers of various sizes for removing screws of different calibers.
- 🔧 Socket wrenches or sockets (most often 8 mm and 10 mm) for removing nuts from the compressor and fasteners doors.
- 🔪 Plastic spatula or old bank cardboard for carefully snapping off decorative panels without scratches.
- 🧤 Work gloves to protect hands from sharp metal edges and dirt.
Particular attention should be paid to safety. Before starting any work, the refrigerator must de-energize. Simply turning off the button is not enough - you need to unplug the cord from the outlet. This is critical because you will be working with electrical components and metal parts that can conduct current if the insulation is accidentally damaged.
⚠️ Warning: Never begin disassembly if the refrigerator has just been running. Let it stand unplugged for at least 30-40 minutes so that the refrigerant in the system turns into a liquid state and the oil flows into the compressor. A sudden start or damage to the tubes under pressure can be dangerous.
Dismantling the doors and removing the internal filling
The first stage of deep disassembly is usually the release of the internal volume and removal of the doors. This greatly facilitates access to the internal components and allows you to work with the case without the risk of dropping heavy glass shelves. First, remove all drawers, shelves and lattice guides.
Refrigerator doors Pozis are most often mounted on powerful hinges that are secured with bolts. In some models, the top hinge is closed with a decorative plug, which must be carefully pryed off with a flat-head screwdriver. After removing the plug, unscrew the top bolts.
The door is a heavy element, and it may move when the last bolt is unscrewed. It is better to carry out this operation with an assistant or use a stop. If the door is equipped with electronics (display, lamp), do not pull it sharply so as not to damage wire cables.
☑️ Preparing to remove doors
After removing the doors, access to the internal space becomes maximum. Now you can focus on removing the internal panels, behind which the ventilation system is hidden. In models with the No Frost system, this is a key step for accessing the fan and heating element. evaporator and ventilation system. In models with the No Frost system, this is the key step for accessing the fan and heating element.
Removing the back wall and accessing the evaporator
In refrigerators Pozis with the No Frost system, the back wall of the freezer compartment is a non-removable part of the body, but it covered with a plastic panel. It is behind this panel that the evaporator radiator is located, in which cooling occurs. To remove it, it is often necessary to remove fasteners inside the chamber.
Carefully inspect the perimeter of the plastic panel. The screws may be hidden under decorative plugs or located in recesses. After unscrewing all visible fasteners, do not rush to pull the panel towards you. It can be held in place by plastic clips around the perimeter.
Use a plastic spatula to carefully go along the junction of the panel and the body. Movements should be confident, but smooth. Old plastic becomes brittle in the cold, and one awkward movement can lead to a crack, which will then have to be masked.
| Element | Type of fastening | Tool | Risks |
|---|---|---|---|
| Decorative panel | Screws + latches | Screwdriver, spatula | Plastic cracks |
| Fan | Screws, connector | Phillips screwdriver | Broken wires |
| Defrost heating element | Clips, contacts | Flat screwdriver | Damage to pipes |
| Temperature sensors | Seat | Without tools | Chip of the sensor housing |
After removing the panel, you will have access to the “heart” of the cooling system. The important thing here is to be extremely careful with aluminum evaporator tubes. Their wall is very thin, and breaking through it with a screwdriver or a careless movement of the hand is as easy as shelling pears. Repairing an evaporator is a complex process that requires refilling the system. vacuuming and refilling the system.
What to do if the panel is frozen?
If you see that the plastic panel is tightly frozen with ice to the evaporator, neither Under no circumstances should you tear it off by force. Plug in the refrigerator for 10-15 minutes or use a hairdryer (carefully, at minimum temperature) to melt the ice. Mechanical chipping of ice with a knife is guaranteed to damage the radiator.
Disassembling the lower part: access to the compressor
The lower part of the refrigerator Pozis is the area where the motor-compressor, start-up relay and capacitor grill are located. Access to this area is usually through the rear metal panel, secured with screws around the perimeter.
After unscrewing all the screws, remove the metal casing. You will have a view of the black cylindrical compressor and condenser coil. Dust and fluff often accumulate here, which can interfere with normal heat exchange. Gently clean the area using a soft brush or vacuum cleaner at minimum power.
If your goal is to replace the compressor or start relay, then further actions require special care. The relay is usually placed directly on the contact group of the compressor and is fixed with a bracket or strip. Before removing the relay, be sure to take a photo of the connection diagram or sketch the colors of the wires.
- 🔌 Disconnect the wires from the starting relay, first remembering their location.
- 🔩 Unscrew the mounting bolts holding the compressor to the frame (usually there are 4 of them).
- 🛑 Do not bend the copper tubes coming from the compressor; the bending radius should be smooth.
When working in the lower zone, remember the presence of oil. If you plan to solder the pipes, prepare a container to drain the oil from the old compressor. It is also worth checking the condition of vibration isolators - rubber bushings on which the motor sits. If they are dry or cracked, replacing them will save you from unnecessary noise when the unit is operating.
Removing the top panel and control unit
In modern models Pozis with electronic control, the upper part of the housing hides the control unit and wiring. Access to it often requires removing a decorative visor or top cover. The fasteners can be located both outside (under the plugs) and inside the refrigeration chamber.
The control unit is the “brain” of the refrigerator. When dismantling it, it is important to comply with electrostatic safety rules. Touch a grounded metal object to remove static charge from your hands before touching the board.
The cables connecting the display, buttons and main board are very delicate. They should not be pulled by the wires. Connectors often have latching tabs that must be unscrewed before removing the connector. A sharp twitch will lead to breakage of the contacts on the board.
⚠️ Attention: If you see swollen capacitors or traces of burning on the board, further operation of the control unit without repair is impossible. Do not try to simply “knock” on the board or close the contacts - this may cause a short circuit in the entire network of the apartment.
After removing the control unit, access to the upper part of the internal cavity opens, where the air ducts often pass (in No Frost models). A lighting lamp can also be located here if it is not built into the side wall.
Nuances of disassembling different Pozis models
The line of refrigerators Pozis is varied: from compact single-chamber models of the series RN to large two-chamber RK i RD. The design may have its own characteristics. For example, in some models the side walls are made of thin metal and can be deformed if handled carelessly.
Models with the system No Frost add complexity in the form of air ducts that pass through the entire body. Their dismantling requires the removal of many intermediate fasteners. Unlike the drip system, where the evaporator is located at the back, here the channels can go both from above and from the side.
Refrigerators with hidden hinges deserve special attention. In them, the door opening mechanism is hidden inside the body, and to remove the door you have to disassemble a significant part of the lining. In such cases, without the manufacturer's service documentation, it is better not to act at random.
Always consider the age of the equipment. Older refrigerators may have a tougher plastic but become brittle over time, while newer models use a more flexible but thinner material. Adapt the pressing force to the material you are working with.
Frequently asked questions (FAQ)
Is it possible to disassemble the refrigerator without disconnecting it from the network?
Absolutely not. Working on internal components, especially the wiring, fan and control unit, requires a complete de-energization. The risk of electric shock or short circuit is too great.
What to do if the plastic is cracked during disassembly?
Small cracks can be carefully soldered with a soldering iron from the inside or sealed with epoxy glue. If the crack is through and visible, you will need to replace the part or use decorative overlays.
Is it necessary to drain the freon before disassembling?
For normal disassembly of the case, removing doors or replacing the relay, you do not need to drain the freon. This is only required when replacing the compressor or evaporator itself, and this must be done by a licensed specialist.
Where can I find the assembly diagram for my Pozis model?
Schemes (explosion diagrams) are usually found in service manuals. They can be found using the full model code (indicated on the nameplate inside the chamber) on the Internet or requested at authorized service centers.
Why did the refrigerator begin to make noise after assembly?
Most likely, you did not secure the compressor well, forgot to install rubber vibration dampers, or some wire is now touching the compressor housing. Also check if the fan is touching ice or wiring.
