The need for access to the internal space of the refrigerator freezer compartment LG can arise for various reasons: from the banal need for thorough defrosting and cleaning hard-to-reach corners to serious repairs, such as replacing a defrost sensor or fan. Owners often encounter situations where frozen ice blocks drawers, or the No Frost system stops effectively cooling food. Self-disassembly is a process that requires accuracy, understanding of the structure of the unit and the presence of a minimum set of tools.
Before proceeding with the dismantling of plastic panels, it is necessary to completely de-energize the device. Electrical safety is priority number one, since there are live electrical components inside the case. It is also worth preparing the workplace in advance, freeing up the space in front of the refrigerator, so that nothing interferes with opening the doors wide and laying out the removed parts.
The design of freezers in models LG with the system No Frost may vary significantly depending on the series and year release. Somewhere the evaporator is hidden behind the back wall, and in other models it can only be accessed after removing the side guides. Understanding exactly what modification you are dealing with will help you avoid breaking plastic latches, which become especially brittle at low temperatures.
Necessary tools and precautions
To successfully carry out disassembly work, you will need not only the desire, but also the right tools. Using unsuitable items such as knives or wide blade screwdrivers can damage the plastic or puncture the cooling circuit, which can be fatal to the refrigerator. The basis of your set should be a Phillips screwdriver various sizes, since the screws can be both large and very small.
Particular attention should be paid to plastic fasteners. In modern models LG manufacturers actively use a system of hidden latches that do not tolerate brute force. For their careful snapping, it is ideal a plastic spatula or an old bank card, which will not scratch the surface or break the fasteners.
- 🔧 Phillips and flathead screwdrivers (preferably dielectric).
- 🧤 Protective gloves for working with sharp edges of ice or metal.
- 💡 Flashlight for illuminating hard-to-reach places inside the chamber.
- 🧊 A container for collecting water in case the ice defrosts.
⚠️ Attention: Never use sharp metal objects to pick out plastic panels. One awkward movement can puncture the thin evaporator tube containing freon, which will lead to expensive repairs or disposal of the equipment.
If there is a significant amount of ice inside the chamber, which prevents access to the screws, it is recommended to let the refrigerator stand in the off state for several hours. An attempt to forcefully tear off frozen parts often ends with cracks in the evaporator housing or breakage of plastic fastening elements.
Preparation for dismantling and defrosting
The first stage of any intervention in the internal structure of the refrigerator is its complete preparation. This is not just a formality, but a critical process to ensure the safety and security of products. Start by disconnecting the appliance from the power supply and removing all products from the freezer.
Next, you need to free up the space from removable elements: shelves, racks and plastic drawers. In models LG drawers often have telescopic guides or special stoppers that must be carefully unlocked before removal. If the drawers are frozen, do not try to pull them out with a jerk - it is better to wait until the ice thaws a little.
☑️ Preparing the refrigerator for disassembly
An important point is to remove the water that forms during the defrosting process. There is usually a hole at the bottom of the freezer to drain condensation, but if it is clogged with ice, water can spread across the floor. Place a rag under the door or install a low tray.
How long does defrosting take?
The time for complete defrosting depends on the amount of ice. Typically the process takes from 4 to 12 hours. It is strictly not recommended to speed up the process with a hairdryer or hot water, since a sharp temperature change can damage the plastic and seals.
Removing the rear panel of the freezer
The rear wall inside the freezer is the main access to evaporator, fan and the defrost system sensors. In most models LG it is secured with several screws and plastic latches. Before starting dismantling, carefully inspect the perimeter of the panel: sometimes the mounting screws may be hidden under decorative plugs or stickers.
The removal process begins with unscrewing all visible screws. Usually their number varies from 4 to 6 pieces. After this, the panel will not fall on its own - it is held in place by hidden fasteners on the sides and top. Carefully pry the edge of the panel with a plastic spatula, moving around the perimeter until you hear the characteristic clicks of the latches being released.
When removing the panel, be careful with the wires that may go to the temperature sensor or backlight, if it is located in this area. Sudden movement can break connections. If the panel cannot be removed, check whether the screws at the bottom, hidden under the decorative strip, are not unscrewed.
| Element | Mounting type | Location | Features |
|---|---|---|---|
| Top screws | Cross (PZ2) | Upper third of the panel | Often hidden under plastic |
| Side latches | Plastic fasteners | On the sides of the panel | Require careful snapping |
| Bottom fasteners | Screws or grooves | Bottom, near the floor of the chamber | Can be covered with decor |
| Sensors | Wired connection | Behind the panel | Do not pull the wires |
⚠️ Attention: Plastic in the freezer The camera becomes brittle after prolonged use. Before removing the panel, it is recommended to slightly warm it with a hairdryer at a minimum temperature to reduce the risk of breaking the latches.
Removing the ventilation system and evaporator
After removing the back panel, you will have access to evaporator the radiator, in which the refrigerant boils, and a fan that drives cold air around the chamber. In refrigerators LG with system No Frost these elements are arranged compactly. The fan is usually mounted in a plastic box or on a bracket next to the radiator.
To remove the fan, you must disconnect the power connector. It can be located directly on the motor body or connected to a common control board. Unscrew the mounting screws holding the fan housing and carefully remove it. Often the blades are clogged with dust and ice chips, which can cause noise.
If access to the evaporator itself is required (for example, to check for leaks or replace the defrost heating element), additional fasteners will need to be removed. The evaporator can be soldered to the tubes or mounted on brackets. Special care is required here: aluminum tubes are very soft and easily deformed.
- ❄️ Check the condition of the defrost heating element for breaks.
- 🌬️ Clean the fan blades from dust and ice.
- 🔌 Make sure the integrity of the wire insulation sensors.
Replacement of sensors and defrost heating element
One of the most common reasons for accessing the inside of the freezer is replacing temperature sensors or defrost heating elements. In models LG the defrost sensor is often attached directly to the evaporator tubes using a special clip or clamp. To replace it, you need to carefully remove the old element, being careful not to damage the wiring.
The defrosting heating element is a curved tube located at the bottom of the evaporator or passing through its lamellas. Replacing it is a more labor-intensive process, since it can be tightly integrated into the structure. The new heating element must exactly match the original in terms of power and geometric dimensions.
When installing new components, it is important to correctly place the sensors in their regular places. If the defrost sensor dangles in the air and does not fit tightly to the evaporator tube, the system will not work correctly, which will lead to either underfreezing of food or freezing of the chamber with ice.
Assembly and performance testing
The refrigerator is assembled in the reverse order of disassembly. Reinstall all the removed elements in their places, making sure that the wires are not pinched by plastic panels and do not touch the moving parts of the fan. Tighten all the screws, but do not overtighten them, so as not to break the threads in the plastic.
After installing the back panel and drawers, you can turn on the refrigerator. In the first minutes of work, listen to the sounds: there should be no extraneous humming, knocking or whistling. The fan should operate smoothly, without vibration. If you replaced the defrost heating element, the first cyclic defrost may take longer.
Check the door for tightness. If during work you touched the seal or removed the door, make sure that it fits tightly around the entire perimeter. A loose fit will lead to constant formation of ice and increased load on the compressor.
Frequently asked questions (FAQ)
Can the evaporator be washed with water after disassembly?
It is strictly not recommended to wash the evaporator under running water. Aluminum slats are easily deformed, and water that gets into electrical connections or under the insulation can cause a short circuit when turned on. It is better to clean with a soft brush or vacuum cleaner.
What to do if the plastic latch breaks when removing the panel?
If the latch breaks off, the panel can be fixed with a small amount of silicone sealant or carefully drill a hole and secure it with a screw with a wide head. The main thing is to ensure a tight fit of the panel so that the air flow flows correctly.
How to understand that the defrost sensor has failed?
The main sign of a sensor malfunction is the formation of a “fur coat” or a block of ice on the back wall of the freezer, while the refrigerator itself continues to work. The system does not see the low temperature and does not turn on the heater to defrost the evaporator.
Do you need to wait before turning it on after disassembly?
If you did not reject the refrigerator and did not work with the refrigerant, there is no need to wait. However, if there was water in the chamber or you wiped the parts with a damp cloth, let the equipment stand turned off for 15-20 minutes so that the moisture evaporates from the electrical contacts.
