Modern refrigerators Daewoo are distinguished by a complex internal architecture and a well-thought-out system No Frost, which greatly simplifies operation, but complicates the maintenance process. The need to completely or partially disassemble the unit arises in situations where it is necessary to replace compressor, repair the defrost system, clean the fan or eliminate extraneous sounds. The owner must be aware that any intervention in the structure requires extreme care and compliance with safety precautions, since inept actions can lead to damage to fragile plastic elements or leakage of the compressor refrigerant.
Before taking active steps, it is necessary to prepare the work space and ensure good lighting of the work area. Most models of the Korean brand have a similar layout of the main components, however, the location of fasteners may vary depending on the specific series and year of manufacture. Carefully studying the device diagram before starting work will help you avoid common mistakes, such as breaking hidden latches or breaking threads in plastic seats. Remember that disassembly is only the first stage, followed by diagnostics and subsequent assembly.
It is also important to note that self-repair may result in denial of warranty service if the device is under warranty. If you are not confident in your abilities or do not have the necessary tool, it is better to contact an authorized service center. However, for those who decide to act independently, knowledge of the sequence of operations will be the key to successful completion of the task. Next, we will consider in detail the stages of dismantling the main components of refrigeration equipment.
Preparation of tools and safety measures
The beginning of any technical procedure must be accompanied by the preparation of the necessary tools and compliance with safety precautions. The first and most important step is to completely disconnect the device from the electrical network. It is not enough to simply turn off the button on the control panel; you must physically remove the cord from the outlet to eliminate the risk of electric shock when working on internal components. It is also recommended to empty the chambers of food in advance and defrost the unit if an ice crust has formed in the system, which may interfere with access to the components.
For high-quality disassembly of the refrigerator Daewoo you will need a standard DIY kit, supplemented with some specific tools. The main work of unscrewing screws will be taken over by a set of screwdrivers with various tips, including Phillips and flathead versions. Plastic housing elements are often fastened with latches, so having a flat blade or a special tool for opening the panels will be extremely useful.
- 🔧 Set of screwdrivers (phillips PH1, PH2 and flat SL)
- 🔑 Adjustable wrench or set of open-end wrenches for compressor nuts
- 🧤 Protective gloves to protect hands from sharp metal edges
- 🔦 Powerful flashlight for illuminating hard-to-reach areas inside the case
Particular attention should be paid to organizing the workplace. The refrigerator takes up a lot of space, so ensure easy access from all sides by moving the appliances away from the wall. Prepare a container to catch any water that may remain in the drainage system or compressor sump after defrosting. It is better to immediately put all removed screws and small parts into separate containers with markings so that there is no confusion during assembly.
⚠️ Attention: Before starting work, be sure to wait until the condensation has completely drained and the internal surfaces have dried, so that water does not get on the electrical contacts or wire insulation.
Removing door panels and internal shelves
The process of disassembling a refrigerator traditionally begins with lightening the structure by removing the doors and internal filling of the chambers. This not only reduces the dimensions of the device for ease of movement, but also opens access to the fastening elements of the main body. Model doors Daewoo usually mounted on powerful metal hinges, which are secured with several bolts. Before removing the top hinge, it is recommended to support the door leaf so that it does not fall and damage the floor covering or your feet.
Removing internal elements such as shelves, drawers and slides requires care, as plastic becomes more brittle at low temperatures. Glass shelves should be removed strictly vertically, avoiding distortions that can lead to jamming in the grooves. Plastic freezer baskets often have additional latches or slides that must be properly snapped off before removal.
☑️ Preparing to remove the doors
When working with the door mechanism, it is important not to damage the electrical harnesses if the door has built-in opening sensors or a control display. In modern models, the connection can be made through a connector, which must be carefully disconnected after removing the decorative trim. If the wires are tense, do not pull them sharply - it is better to release the cable from the clips along the body.
- 🚪 Remove the top hinge, having first secured the door in a vertical position
- 🧊 Remove all glass shelves, having previously freed them from the clamps
- 📦 Take out the plastic ones containers and boxes for vegetables, observing the angle of inclination
Disassembling the rear panel and access to the compressor
The rear wall of the refrigerator Daewoo hides one of the most important components - the compressor-condenser unit. To access it, you need to turn the refrigerator on its side or carefully tilt it, placing a soft surface so as not to scratch the front panel. The crankcase engine is mounted on a special frame in the lower part of the housing and is covered with a metal or plastic casing, which is bolted on.
After removing the protective casing, a view of the compressor, start relay, condenser and copper pipes of the circulation system opens. It is important to be extremely careful here: copper tubes are thin-walled and easily deformed, and their damage will lead to an immediate release of refrigerant and the need for complex repairs involving a vacuum pump and a filling station. Visual inspection allows you to identify traces of oil that may indicate a leak, or melted wire insulation.
| Component | Function | Removal features |
|---|---|---|
| Compressor | Compression and refrigerant circulation | Requires unsoldering tubes or unscrewing nuts |
| Start relay | Starting the compressor engine | Removed manually, fixed on three contacts |
| Fan | Condenser cooling | Fixed on a bracket, has an electrical connector |
| Filter drier | Cleaning freon from moisture | Located at the outlet of the condenser, requires caution |
If you plan to replace the compressor, you must take into account that new models may have different mounting dimensions for the mounting feet. In this case, it may be necessary to adapt the mounting frame or use adapter washers. Also, when working with the rear panel, dust and dirt are often found on the fins of the condenser radiator, which must be removed with a soft brush or vacuum cleaner to restore heat exchange.
⚠️ Attention: It is strictly forbidden to bend copper tubes at an angle of less than 90 degrees, as this blocks the gas circulation channel and disables the system.
How to check the serviceability of the compressor without disassembling?
For initial diagnostics, you can measure the resistance of the windings through the contacts of the starting relay. Normal values range from 20 to 40 ohms. If the resistance is infinitely large or equal to zero, the motor is faulty.
Removing the No Frost system and evaporator
The system No Frost in refrigerators Daewoo is located behind the rear wall of the freezer and includes an evaporator, an air injection fan and defrost heater. To get to these components, you need to remove the plastic panel inside the freezer, which is usually secured with screws and plastic clips around the perimeter. You need to act slowly, evenly pressing the clamps in a circle so as not to break them.
After removing the panel, access to the aluminum evaporator radiator opens, which is often covered with a layer of ice even in a working device if the door seal was previously broken. The fan, which circulates cold air, is attached directly to the evaporator body or to the chamber partition. Its dismantling requires disconnecting the power connector, which may be located in a hard-to-reach place.
- ❄️ Carefully bend the plastic clips on the back panel of the freezer
- 🌬️ Disconnect the fan power connector, having previously photographed the connection diagram
- 🔥 Check the integrity defrost heating element located under the evaporator
A frequent problem in this area is the failure of the defrost sensor or the burnout of the heating element, which leads to fouling of the evaporator with a “fur coat” and the cessation of cooling. When replacing these elements, it is important to thoroughly clean the surface of the evaporator from old ice and dirt, using a hairdryer or warm water, but under no circumstances using sharp objects to chip the ice, as thin-walled tubes can be pierced.
Removing the front control panel and electronics
The electronic control module in refrigerators Daewoo most often located in the upper part of the case, hidden behind a decorative panel. To access it, you need to dismantle the top cover of the refrigerator compartment or remove the cover on which the indicators and buttons are located. Fastening can be carried out either with screws or with powerful latches that require the use of a plastic spatula.
The control board is a complex electronic unit with many connections. Before completely removing it, you must disconnect all the cables and connectors going to the temperature sensors, lighting lamps, fans and compressor. It is recommended to take photographs of each stage of disconnecting the wires, as the color coding may not be obvious, and mixed-up contacts can lead to a short circuit.
In some models, the control panel is integrated into the door, which complicates the dismantling process due to the presence of flexible cables passing through the hinge assembly. In such cases, the inner door trim is first removed, after which access to the reverse side of the board is opened. Be attentive to the condition of the cables: they do not like repeated bending and may have microcracks.
⚠️ Attention: Electronic components are sensitive to static electricity, so before touching the board it is recommended to touch a grounded metal object or use an antistatic wrist strap.
Assembly and performance check
The process of assembling a refrigerator Daewoo is carried out in the reverse order of disassembly, but requires even greater attention to detail. It is important to make sure that all screws are tightened all the way, but without excessive force, which could strip the threads in the plastic. Pay special attention to the tightness of the connections in the compressor area, if work was done with tubes, and to the reliability of the electrical connectors.
After all components are fully assembled and the doors are in place, the refrigerator can be plugged in. However, you should not immediately load it with products. Allow the unit to idle for 2-4 hours to reach operating temperature and ensure there are no unusual noises, vibrations or leaks. Monitor the operation of the fans and the on-off cycles of the compressor.
- 🔍 Check the tightness of all panels and the absence of gaps
- 🔊 Listen to the operation of the engine: there should be no knocking or humming
- 🌡️ Make sure that the chambers begin to decrease temperature in normal mode
If after assembly the refrigerator makes unusual sounds or does not freeze, you must re-check that all components are connected correctly. Often the cause of problems is a forgotten tool inside the case or an incorrectly installed fan cover that can touch the blades. In case of doubt, it is better not to take risks and turn to professionals.
Is it possible to disassemble a Daewoo refrigerator without removing the door?
In most cases, for full access to the internal components, especially the system No Frost and evaporator, removing the doors is not a necessary step. However, dismantling the doors greatly simplifies access to the interior and reduces the risk of damage to seals or hinges during operation. If the dimensions of the room allow, the refrigerator can be disassembled in its assembled form, but this is less convenient.
What tools are needed to remove plastic panels?
To remove plastic panels, it is best to use specialized plastic spatulas for opening cases or old bank cards. The use of metal screwdrivers is not recommended as they easily leave scratches on visible surfaces and can crack fragile plastic if handled carelessly. If metal is necessary, wrap the tip with electrical tape.
What to do if the refrigerator hums loudly after assembly?
Humming after assembly can be caused by several reasons: vibration of loose parts, fan blades touching the housing, or improper installation of the compressor on the frame. Also check that the tubes are not touching each other or the cabinet walls. If the noise does not stop, it is necessary to re-check the assembly quality of all components.
Is it necessary to pump out freon before disassembling?
Pumping out freon is required only if you plan to interfere with the sealed circuit of the cooling system (replacing the compressor, repairing pipes). To replace electronics, fans, heating elements or plastic elements, disassembling the refrigerant circulation system is not required, and the gas remains inside the circuit.
