Dismantling household appliances is a process that requires not only physical strength, but also a deep understanding of the structure of the unit. When you decide completely disassemble the refrigerator, you are faced with the task of not just removing the doors, but also getting to hidden components such as the compressor, evaporator and control system. This is often necessary to replace a failed motor, clear a blockage in a capillary tube, or deep clean the system of mold and old freon. An incorrect approach to dismantling can lead to damage to fragile plastic elements or, worse, to depressurization of the circuit.
Before starting work, it is critical to disconnect the unit from the power supply and let it stand for several hours. This will allow the oil to drain into the compressor crankcase and reduce the pressure in the system, which minimizes the risks of cutting the pipes. In this article we will look in detail at the stages of complete disassembly, starting from external elements and ending with removal compressor-condensing unit. Be prepared for the fact that some connections may be soldered or become very rusty over time.
It is worth noting that the design of different models, be it Indesit, Beko or Liebherr, may differ significantly. Somewhere you will find hidden loops, and somewhere - complex electronic control systems that require preliminary disconnection of the loops. When disassembling refrigerators with the No Frost system, primary attention is paid to carefully removing fans and sensors, since their wiring is often laid in narrow channels. Next we will move on to specific steps that will help you safely dismantle the equipment.
Preparation of the workplace and the necessary tools
High-quality disassembly is impossible without the right tool. You will need not only a standard set of screwdrivers, but also specialized tools for working with metal and plastic. The basic rule is not to use force where the right tool can be used, so as not to break plastic latches or threaded connections. Prepare in advance a container for draining the oil and a rag for wiping surfaces.
For work you will need:
- 🔧 A set of Phillips and flat-head screwdrivers of various sizes for screws of different lengths.
- 🔩 Socket wrenches or sockets (often a size of 8 mm or 10 mm is required) for the compressor nuts.
- ✂️ Side cutters or wire cutters for cutting copper tubes (if you plan to completely dispose of or replace the circuit).
- 🧤 Protective gloves, as there may be sharp metal edges and residues inside refrigerant.
Pay special attention to organizing the space. The refrigerator is heavy and its parts can be bulky. Make sure you have a clear area for storing removed shelves and doors. If you plan to work with the electrical part, it will be useful to have a multimeter to check the integrity of the motor windings before final removal.
⚠️ Attention: Before starting any work, make sure that the refrigerator is unplugged for at least 2-3 hours. Residual voltage in the start relay capacitors can be dangerous, and the oil in the compressor must cool and settle.
Dismantling doors and interior shelves
The first step is always to free up the internal space and remove the hanging elements. Start by removing all removable shelves, vegetable drawers and door containers. This will significantly reduce the weight of the structure and provide access to the mounting points. Be careful with glass shelves - they are fragile and can burst if handled carelessly guides.
Removing the doors requires the help of a second person, since even an empty door is heavy and can drop the body if it is skewed. The algorithm of actions is usually the following:
- 🚪 Remove the decorative plugs from the hinges by prying them with a thin screwdriver or knife.
- 🔩 Unscrew the fastening bolts of the upper hinge (for models with a top freezer) or the lower one, if the design is different.
- 🤲 While holding the door, carefully lift it to remove the bottom hinge pin from the hole.
After removing the doors, inspect the rubber seals. If you are disassembling the refrigerator to replace them, now is the time to carefully pull the cuff out of the groove. In models with the system No Frost it is also worth checking the condition of the air ducts, which are often attached to the inner wall of the chamber. Their dismantling may require removing additional screws inside the chamber.
☑️ Preparation for removing the doors
Removing the rear panel and access to the insides
To get to the “heart” of the refrigerator, you need to remove the rear metal panel. It closes the compressor, condenser and start relay. Fasteners are usually located around the perimeter of the sheet. In older models, the screws may be covered with rust, so it is recommended to pre-treat them with a penetrating lubricant such as WD-40 and give it time to work.
Panel removal process:
- 🔩 Remove all screws around the perimeter of the back wall, remembering to check the bottom at the base.
- 🌬️ Carefully bend the panel, trying not to damage the condenser tubes that may be adjacent to it.
- 🔌 Disconnect the wires going to the fan (if there is one on the outside) or sensors, having previously photographed their position.
Under the panel you will see the compressor, drying filter and capacitor grid. It is important here not to damage the thin tubes through which the refrigerant circulates. If your goal is to replace the compressor, then at this stage you can already begin to unsolder the tubes, but to completely disassemble the housing it is better to first remove the entire unit from the frame. Pay attention to the condition vibration bushingson which the motor stands.
⚠️ Attention: The capacitor grid (black coil at the back) is very fragile. It is easy to pierce aluminum with the sharp edge of a screwdriver or a careless movement, which will lead to freon leakage and the need for expensive refilling.
Disassembling the freezer and the No Frost system
If your refrigerator is equipped with a system No Frost, then the freezer is a complex assembly with an evaporator, Heating elements and fan. Access to them often requires removing the inner back wall of the camera. It can be attached with screws or held on with plastic latches. Act carefully so as not to break the fragile plastic, which becomes even more brittle in the cold.
The main elements that will have to be dismantled inside:
- ❄️ Air circulation fan - usually hidden behind a plastic casing.
- 🔥 Defrost heating element - located at the bottom of the evaporator, often filled with ice or covered with scale.
- 🌡️ Temperature and defrost sensors - small devices in contact with the evaporator tubes.
When removing the evaporator, be prepared for the fact that it may be frozen to the wall. Don't try to tear it off by force - it's better to let it thaw completely. In some models, for example Samsung or LG, the evaporator can be foamed in the housing, and its removal requires partial destruction of the inner lining, which makes further operation of the refrigerator without an external chamber impossible. In such cases, they talk about complete disassembly for the purpose of disposal or major repairs.
What to do if the plastic wall is cracked?
If, when removing the back wall of the camera, you heard a crunch and the plastic burst, do not panic. For temporary repairs, you can use food-grade epoxy resin or a special sealant for refrigerators. However, for complete tightness and preservation of the cold, it is better to order a new panel from the manufacturer or a service center, since the crack will allow warm air to pass through and cause ice growth.
Removing the compressor and electrical part
The most important stage is working with the compressor. This is a heavy black “barrel” mounted on the frame. Before removing it, you must disconnect the electrical contacts. The start and safety relays are usually simply removed from the compressor pins, but sometimes they can be glued or secured with a clamp. Remember the connection diagram or take a photo so that during assembly (if it is planned) you do not mix up the contacts.
Table of main components of the compressor compartment:
| Unit | Function | Dismantling features |
|---|---|---|
| Compressor | Refrigerant compression | Requires unsoldering of tubes or sawing |
| Condenser | Gas cooling and condensation | Fragile, requires care when bending |
| Filter drier | Removing moisture from the system | Disposable element, cut off |
| Start relay | Starting the engine | Removed from the pins, fragile plastic |
To physically remove the compressor, you need to saw through the copper suction and discharge tubes. Use a pipe cutter to avoid creating metal shavings that could get caught inside the system. If you don’t have a pipe cutter, you can cut the pipes with powerful side cutters, but be sure to clamp the cut area so that the chips don’t fly inside. After disconnecting the tubes, unscrew the bolts securing the compressor feet to the frame. Now the unit is free.
Disassembling the case and insulation
Complete disassembly of the refrigerator also involves dismantling the case itself, which is often required during disposal or serious repairs associated with replacing the internal chamber. The body is a “sandwich” of outer metal, a layer of polyurethane foam insulation and inner plastic. It is almost impossible to separate these layers without damage.
If you need to remove the outer walls, look for hidden screws under the decorative overlays, at the bottom of the base or inside the chamber under the plugs. In some models, the side walls simply hook into the back and front panels. However, it is worth remembering that polyurethane foam strongly bonds metals. When you try to remove the wall, you will most likely tear the insulation.
The internal plastic tank can also be secured with screws around the perimeter or supported by polyurethane foam. Modern models often use the “foam assembly” method, where the inner chamber is inserted into the outer one, and the space is filled with foam. It is impossible to disassemble such a monolith without destruction. Therefore, if you see that the elements are tightly foamed, further disassembly makes sense only in the context of separating materials for recycling.
⚠️ Attention: Polyurethane foam insulation releases toxic substances when burned. Never try to melt or burn disassembled parts of a refrigerator at home or over an open fire.
Disposal and sorting of materials
After the refrigerator is completely disassembled, you will be presented with a pile of different materials: ferrous and non-ferrous metal, plastic, rubber and insulation. For proper disposal, all this must be sorted. Copper from motor tubing and windings is the most prized, followed by aluminum and steel. Plastic and rubber can also be handed over to special collection points.
The sorting process looks like this:
- 🔩 Metal body and shelves are handed over as ferrous scrap.
- 🟠 Copper tubes and motor windings - separately as non-ferrous metal.
- 🧊 Plastic parts and seals - in a container for plastic or rubber.
- ⚡ Electronics and wires - require special processing due to the content of precious metals.
It is important to remember about environmental safety. Refrigerants that may remain in the system, when released into the atmosphere, contribute to the destruction of the ozone layer. Therefore, professional disposal involves evacuating the remaining gas before disassembling. At home, when sawing through the pipes, the gas simply evaporates, which is not good, but is often inevitable when doing DIY repairs.
Disassembling a refrigerator is a complex technical process that requires care and compliance with safety precautions. Correctly performed dismantling will not only allow you to replace the faulty unit, but will also ensure the safe disposal of used equipment. Always evaluate your strength: if you are not sure about the ability to put the unit back together, it is better to limit yourself to partial disassembly or contact specialists.
Is it possible to restore a foamed evaporator?
If the evaporator was foamed in the housing and you cut it out, it is almost impossible to restore the factory tightness and thermal insulation. Attempting to glue a new evaporator with glue or sealant will lead to poor heat transfer and constant formation of condensation between the walls, which will cause corrosion and an unpleasant odor. In such cases, it is recommended to replace the entire internal chamber or purchase a new refrigerator.
Do you need to drain the oil from the compressor before disassembling?
Yes, if you plan to cut the compressor housing or dispose of it, the oil must be drained. It is a waste product and pollutes the environment. There is a service hole in the compressor or you can drill the bottom (be careful, sparks!) to drain the oil into a container. The oil volume can be from 200 to 500 ml, depending on the model.
Is the freon released when disassembling the tubes dangerous?
Modern freons (R134a, R600a) in small quantities contained in a household refrigerator are not toxic to humans with short-term contact in the open air. However, R600a (isobutane) is an explosive gas. Therefore, it is strictly forbidden to smoke or use open fire near the refrigerator being cut. Ventilate the room.
Is it possible to disassemble the refrigerator without damaging the tubes?
It is possible to disassemble the refrigerator completely, maintaining the tightness of the system (tubes), only up to a certain stage. You can remove doors, shelves, back cover, fan and even the compressor itself (if you use a special puller or carefully unsolder the tubes and then plug). But if we are talking about complete disposal of the case, then the integrity of the circuit cannot be preserved.
What to do with rusty bolts that cannot be unscrewed?
Do not use excessive force so as not to tear off the bolt head. Treat the joint with penetrating lubricant (WD-40, kerosene) and leave for 15-20 minutes. You can try gently tapping the bolt through the extension with a hammer to destroy the rust layer. If the cap is torn off, use an extractor or try to clamp the rest of the bolt with pliers.
