Dismantling refrigeration equipment is a complex technical process that requires not only physical effort, but also strict adherence to safety precautions. Most often, this procedure is resorted to when it is necessary to dispose of old equipment, overhaul or replace the compressor. Unlike simply disassembling consumer electronics, the critical factor here is the presence of refrigerant in the system.
Modern models, be it Indesit, Atlant or Bekohave a similar design, but may differ in the location of the components. Before starting work, it is necessary to clearly understand the risks: improper handling refrigerant can cause harm to the environment and health, and breaking the tightness of the tubes without prior preparation will lead to moisture getting inside the system. That is why it is important to act consistently and carefully.
In this article we will analyze in detail the stages of preparation, safe removal of gas residues and mechanical disassembly of the housing. You will learn what tools are needed and how to avoid common mistakes that can lead to injury or damage to equipment.
Safety measures and workplace preparation
The first thing you need to do before starting any manipulations is to disconnect the device from the electrical network. The power cord must be removed from the outlet, and the cable itself should preferably be fixed or removed to eliminate the risk of accidental activation. Working with electrical appliances, even when turned off, requires caution, since residual charges in the capacitors may remain in the circuit.
The second critical point is the ventilation of the room. If you plan to open the system in which it remains freon, make sure that the windows are open. Although modern refrigerants are not toxic in low concentrations, they are heavier than air and can displace oxygen in a confined space. In addition, when heated or in contact with an open flame, freon can decompose into dangerous compounds.
⚠️ Attention: Never use an open fire to warm up the tubes unless you are 100% sure that the system is completely empty and there is no pressure in it. This may lead to an explosion of oil and gas vapors.
Prepare the necessary tools in advance. You will need different types of screwdrivers, pliers, wire cutters, and possibly wrenches. Prepare a flat container to collect oil and condensation. It is best to work with gloves, since internal metal parts may have sharp edges, and oil from the compressor is difficult to wash off the skin.
Organize the space around the unit. The refrigerator must stand stable, preferably on a flat surface. If the floor is slippery, place rubber mats or thick cardboard under your feet. This will prevent sudden displacement of the heavy housing during the removal of doors or the compressor.
Assessing the condition of the refrigerant and releasing pressure
The main question before disassembly: is there any remaining in the system freon? If the refrigerator stopped cooling several years ago or was punctured during defrosting, the gas has most likely already escaped. However, if the unit simply stops turning on, the pressure in the circuit remains. You can check this by carefully filing the thinnest copper tube near the compressor.
If you hear a characteristic hissing sound, it means the system is sealed and gas is inside. In professional settings, freon is pumped out by special stations for subsequent disposal or reuse. At home, in preparation for disposal, the gas is simply vented in a well-ventilated area.
The venting process should be slow. You should not bite the whole pipe at once. It is best to make a small cut with a file at the bend of the tube so that the gas comes out gradually. A sudden change in pressure can spray the oil in the compressor throughout the room.
⚠️ Attention: It is strictly prohibited to burn freon or release it in close proximity to fire sources. At high temperatures, it turns into phosgene, a chemical warfare agent.
After the hissing has stopped, we can assume that the pressure in the system has equalized atmospheric pressure. Now you can move on to more active steps to separate the nodes. Remember that even after bleeding, a certain amount of gas dissolved in the oil may remain in the pipes and compressor, so there is no point in maintaining complete tightness if the goal is disposal.
Dismantling doors and removing internal fittings
Disassembling the housing always begins with the hinged elements. Refrigerator doors are the heaviest and largest removable element. Their weight can reach 20-30 kilograms, so this operation should be performed by two people. If you are working alone, be sure to remove all shelves and drawers from the doors to reduce the weight and load on the hinges.
To remove the door, you need to find the hinge attachment points. They are usually closed with decorative plastic plugs. Gently pry them off with a flathead screwdriver. Under the plugs you will find bolts that need to be unscrewed. In some models Samsung or LG the hinges may be hidden under plastic covers at the end of the body.
☑️ Removing doors
After removing the doors, the refrigerator becomes much lighter and more compact. Now you can remove all the internal contents: glass shelves, plastic containers, egg trays and lamp covers. The glass should be folded separately, as it may break during further disassembly of the metal case.
Pay attention to the No Frost system. If your refrigerator has an automatic defrost, there is an evaporator and fan located inside, behind the back wall of the freezer. You can get to them only by removing the inner plastic lining. The mounting screws are often hidden under plugs or located inside drawers.
Disassembling the rear panel and accessing the compressor
The most important part, containing the main technical components, is located at the bottom rear. Here is located compressora capacitor (radiator grille) and a starting relay. Access to them is usually closed with a metal or cardboard panel, which is screwed with self-tapping screws around the perimeter.
Unscrewing the panel, you will see a black “tank” - this is the motor-compressor. Three copper tubes approach it: two extend from the housing (high pressure and process outlet) and one enters (low pressure inlet from the evaporator). Also, an electrical cable covered with a plastic casing is suitable for the compressor.
| Element | Function | Material | Danger |
|---|---|---|---|
| Compressor | Freon circulation | Steel, copper | High pressure, oil |
| Condenser | Gas cooling | Aluminium, steel | Sharp edges |
| Filter drier | Moisture removal | Copper, zeolite | Chemical filler |
| Capillary tube | Throttling | Copper | Clogging if damaged |
To completely dismantle the unit, it is necessary to disconnect the electrics. Remove the plastic cup covering the contacts. Inside you will see a start relay and a thermal relay. They simply slide onto the compressor pins, so removing them requires no tools, just care. Disconnect the wires leading from the relay to the common terminal box.
Why do you need a filter drier?
The filter drier (the copper cylinder on the back of the refrigerator) contains zeolite, which absorbs moisture from the system. When the circuit depressurizes, it quickly becomes saturated with water from the air, so during repairs it is always replaced with a new one.
Now you can disconnect the copper tubes. It's best to cut them with a pipe cutter or wire cutters as close to the condenser and evaporator as possible to avoid damaging the grille if you plan to keep it. If the goal is recycling, you can eat the pipes in any convenient place.
Removing the compressor and disposing of components
The compressor is attached to the metal base of the refrigerator with four bolts or welded studs. You may need a socket wrench or socket to unscrew them. Often the bolts stick or sour, so pre-treat them with a penetrating lubricant (for example, WD-40) and let them sit for 10-15 minutes.
After unscrewing the fasteners, the compressor can still be held by the tubes. Make sure they have a snack. The motor-compressor weighs about 8-10 kilograms, so remove it carefully, holding it with your hands. There is always technical oil at the bottom of the compartment - this is normal, it is used to lubricate rubbing parts.
The capacitor grill deserves special attention. In older models it can be steel and black, in new ones it can be aluminum and is often located flush with the side walls (inside the case). If the grille is external, it can be bent or cut off. Aluminum heat exchangers are valued higher than steel when delivering non-ferrous metals.
Don't forget about the filter drier. This is a small copper cylinder located on the back of the refrigerator, usually in front of the evaporator inlet. Inside it there is a zeolite, which is a sorbent. When disposing of it, you do not need to open it, but it is worth knowing about its presence.
After removing all the components, an empty metal cabinet remains. Inside it may be a layer of polyurethane foam insulation. If you are disassembling a refrigerator for scrapping, then the cabinet is compressed in a press. To reuse the body (for example, to create a smokehouse or cabinet), the insides must be thoroughly cleaned of any remaining foam and oil.
Typical mistakes and important nuances
One of the most common mistakes is trying to tear off the tubes by force without biting them. Copper is a soft metal, but a sharp tug can damage the connections inside the sealed areas or deform the thin walls of the evaporator. Always use the correct tool for cutting metal.
Another important point is the safety of electrical wiring if you plan to reuse parts. Do not pull the wires out of the insulation, but carefully disconnect them at the twists or terminals. Refrigerator wire strands are usually made of copper, which is also valuable.
⚠️ Attention: Some older models used R600a (isobutane) as a refrigerant. It's explosive! If this substance is indicated on the nameplate (sticker on the back), strictly avoid any sparks and work only with good ventilation.
Do not ignore plastic elements. Shelves, drawers and handles are often made of high-quality ABS plastic, which can be used for repairing other devices or for household purposes. The glass of the shelves can also be useful if it is intact.
It is important to consider that the design of refrigerators from different years of manufacture may differ significantly. Models of the late 90s and early 2000s often featured more massive designs and more steel elements. Modern units strive for minimalism and the use of composite materials.
Frequently asked questions (FAQ)
Is it possible to disassemble a refrigerator if it is still under warranty?
No, independent breaking of seals and opening of technically complex components, such as a compressor or piping system, is automatic voids the manufacturer's warranty. If the refrigerator breaks down, contact an authorized service center.
Is compressor oil dangerous for the skin?
The technical oil used in refrigerators is mineral or synthetic. It is not a potent poison, but may cause irritation, allergic reactions or dermatitis with prolonged contact. Wear gloves and wash your hands thoroughly with soap after completing work.
What to do with freon if you need to throw away your refrigerator?
According to environmental standards, freon cannot simply be released into the atmosphere. However, in domestic conditions, when disposing of old equipment, the gas is usually released outdoors or in a ventilated area before the housing is scrapped. For complete environmentally friendly disposal, it is better to hand over the equipment to a specialized collection point.
Can a compressor from a refrigerator be used for other purposes?
Yes, compressors are widely used by craftsmen to create homemade airbrushes, tire inflators or vacuum units. However, it is worth remembering that such compressors are not designed for constant operation under high pressure and require the installation of a receiver and a cooling system.
Where can I find a disassembly diagram for my model?
The exact diagram (exploded view) can be found in the service manuals for a specific model. They are often posted on specialized forums for repairing household appliances or on manufacturers' websites in the support section.
