The decision to disassemble the refrigerator yourself is often dictated by the need to replace a failed unit or dispose of an old unit. Dismantling of household appliances requires not only physical strength, but also a clear understanding of the structure of internal systems. Errors at the stage of removing panels can lead to damage to fragile tubes or damage to the integrity of the insulation.
Before picking up a tool, you need to realize that you are dealing with equipment that is under pressure and contains refrigerant. In modern models, such as Indesit or LG, the layout of components may differ significantly from Soviet analogues like Biryusa. Your task is to carefully get to the desired element without turning serviceable parts into scrap.
In this guide we will analyze the algorithm of actions for safely opening the case and removing the main units. You will learn what tools are needed, how to properly disconnect the electrics, and in what order it is best to carry out the work. Remember that competent disassembly is already half of a successful repair.
Preparation of the workplace and tools
Organizing space is a critical stage that is often ignored by beginners. You will need a free area measuring at least 2x2 meters, where you can put the removed shelves and doors. Tools They should be laid out in an accessible manner so as not to look for a screwdriver at the most inopportune moment.
For work you will need a basic set of a home craftsman, supplemented with specific elements. Do not use rusty or damaged tools, as a slipped screwdriver tip can pierce the evaporator or damage the plastic of the case.
- 🔧 A set of screwdrivers (phillips and flat of various sizes) for removing fasteners.
- 🔩 Pliers and side cutters for working with clamps and wires.
- 🔪 Construction knife or scalpel for carefully opening foamed areas.
- 🧤 Thick gloves to protect your hands from sharp metal edges.
⚠️ Attention: Before starting any work, be sure to disconnect the refrigerator from the power supply! Unplug the plug from the socket and make sure that the cable is not damaged.
Pay special attention to lighting. The interior of a refrigerator is dark, and poor light will cause you to simply miss small latches or hidden screws. If you plan to disassemble the rear part where compressoris located, make sure that there is no dust there that could get into the respiratory tract or eyes.
☑️ Preparation for disassembly
Dismantling external elements and door groups
The first step is always to release the internal volume and remove the hanging elements. Remove all shelves, drawers and containers. This will not only make the construction easier, but will also allow you to see the attachment points for the internal panels. It is better to remove the door shelves immediately so that they do not interfere when unscrewing the hinges.
Removing doors is a process that requires caution, since they have significant weight. In models with the system No Frost the doors often have electrical circuits for controlling the display or buttons. Do not jerk the door sharply.
The algorithm of actions usually looks like this: first, remove the decorative plug on the top hinge, then unscrew the bolts. After this, the door must be held and carefully lifted to remove it from the lower support. If the model is two-chamber, the sequence may vary depending on the design of the hinges.
When working with fasteners, use a magnetic tray to fold the screws. Small fasteners tend to roll under the refrigerator or get lost in the carpet pile, which can stop the entire disassembly process.
Disassembling the interior and the No Frost system
When you reach the inner chamber, you will be faced with plastic panels hiding the evaporator and fan. In refrigerators with an automatic defrosting system or system No Frost this is where replacement of the heating element or defrost sensor is most often required.
Internal panels are often secured using hidden latches and screws, covered with decorative plugs. Proceed carefully: plastic becomes brittle in the cold, and one awkward movement can break the fastening eye. It is not recommended to heat the plastic with a hairdryer, as the seals can be deformed.
To access evaporator in some models you have to dismantle the entire inner box. This is a labor-intensive process that requires disconnecting the air ducts. In older models, the evaporator may be foamed into the wall, and its replacement without damaging the housing is impossible.
- ❄️ Remove the back wall of the chamber by unscrewing the screws around the perimeter.
- 🌬️ Disconnect the air duct corrugation if it is in the way access to the node.
- 🔌 Carefully disconnect the temperature sensor connectors.
If you find ice on the evaporator, do not try to chop it off with a knife. A breakdown of the evaporator tube will lead to a freon leak and the need for complex repairs involving soldering and refilling. Let the ice melt naturally or use the warm air of a hairdryer at a safe distance.
Difficulties with plastic panels
If the panel does not come off, do not use force. Check to see if you forgot to remove the screws at the bottom or under the decorative trims. Often the fasteners are hidden under rubber seals.
Access to the compressor unit
The back of the refrigerator is the “heart” of the system. Here is located compressora capacitor array and a starting relay. Access to this unit is usually open, since the back wall in most models is removable or absent altogether.
The first thing to do is remove the protective casing (if there is one) and disconnect the wires from the compressor. Remember or take a photo of the connection diagram. Usually there are three contacts: phase, neutral and ground, plus the start relay terminals.
To remove the compressor itself, you will need to cut through the copper tubes. This needs to be done with wire cutters, having first stepped back a few centimeters from the body so that there is room left for soldering the new unit. You cannot cut the tubes with a hacksaw - metal shavings will get into the system and damage the new compressor.
⚠️ Attention: Oil and refrigerant under residual pressure may remain in the tubes. Be prepared for the possibility of a hissing sound when biting through the tube. Work in a ventilated area.
The compressor is mounted on four studs through rubber shock absorbers. The nuts may be over-tightened or rusted. Use a penetrating lubricant if the threads do not budge. When removing the unit, support it so that it does not fall on your feet - the weight of the motor can reach 10-12 kg.
| Element | Function | Signs of malfunction | Difficulty of replacement |
|---|---|---|---|
| Compressor | Refrigerant circulation | Does not turn on, hums, does not cool | High (requires soldering) |
| Start relay | Starting the engine | Clicks, but does not start | Low (replacement in 5 minutes) |
| Defrost heating element | Evaporator defrosting | Ice build-up in the chamber | Average (disassembling the chamber) |
| Fan | Air circulation | Noise, lack of cold in the upper shelves | Average |
Removing the radiator and working with copper tubes
The condenser (radiator) is located on the back wall and is a coil made of a black tube. Its damage is one of the most common problems caused by careless transportation or disassembly. If your goal is recycling, the radiator is sold as non-ferrous metal.
The radiator is usually attached to clips or glued to the back panel. When dismantling, try not to bend the tubes at an acute angle. Copper is a soft metal, but with repeated bending it breaks.
If you are changing the filter drier (which is necessary when opening the circuit), use a soldering iron or torch. The old filter is bitten off, the new one is soldered in. The direction of flow is indicated by an arrow on the filter housing. Incorrect installation will lead to rapid failure of the new compressor.
When working with open ends of the tubes, try to minimize the time they are in contact with air. No moisture should get inside the system. If the repair is delayed, it is better to plug the ends of the tubes with rubber plugs or seal them with tape.
- 🔥 Use soft solder and flux for soldering copper connections.
- 🛑 Do not allow the tubes to overheat, so as not to melt the insulation of the wires nearby.
- 🧹 Clean the soldering areas to a shine before applying solder.
It is important to understand that the system is airtight. Any microcrack that you may not notice during disassembly will cause a freon leak a month after assembly. Therefore, visual inspection of the condition of the tubes is mandatory.
Recycling and sorting of parts
After the refrigerator is disassembled, you are left with a pile of parts. Proper sorting is important not only for order, but also for the environment. Plastic, metal and electronics must be disposed of in different ways.
The compressor contains copper and steel, as well as oil residues. It must be taken to collection points for non-ferrous metals, after draining the oil into an airtight container. It is strictly prohibited to pour industrial oil down the drain or onto the ground.
Plastic panels and foam insulation (polyurethane foam) are often accepted as household waste, but it is better to find a specialized recycling point. When burning, polystyrene foam releases toxic substances, so you cannot burn it at the dacha.
⚠️ Attention: The refrigerant (freon) contained in the system destroys the ozone layer. When disassembling the radiator and compressor, try not to bleed off the gas on purpose. Ideally, the gas should be pumped out by a technician with the equipment.
Electronic control boards contain precious metals, but also hazardous substances. They cannot simply be thrown into a common container. Collect all electronics in a separate bag and take them to a special container for batteries and electronics.
If you disassembled the refrigerator for spare parts for repair, immediately pack the removed components in boxes or tight bags, labeling them with a marker. In a month, you may forget where this part came from and what model it was intended for.
What to do with foam?
Mounting foam inside the refrigerator body is an excellent heat insulator. If you are only replacing the compressor, try to disturb the foam layer as little as possible. It is extremely difficult to restore its tightness and thermal insulation properties.
Is it possible to disassemble a refrigerator without damaging the freon circuit?
It is possible to completely avoid intervention in the circuit only by replacing external elements (doors, shelves, electronics). To replace a compressor, filter or evaporator, depressurization of the system is inevitable.
Is compressor oil dangerous?
Technical compressor oil is toxic if ingested and harmful to the skin. Wear gloves and do not allow it to come into contact with food.
Is a vacuum pump needed when replacing parts?
Yes, if the sealed circuit has been opened. Evacuation is necessary to remove moisture and air from the system before charging with freon. Without this, the refrigerator will not work.
How much does a disassembled refrigerator weigh?
Weight depends on the model. The main mass consists of the steel housing and the compressor. On average, after removing all plastic elements and glass, about 70-80% of the original weight remains.
Where can I find a disassembly diagram for my model?
Exploded view diagrams can often be found in service manuals on manufacturers' websites or specialized forums for repairing household appliances by entering the exact model number (PNC).
