The sealing rubber is a critical element of the design of your of the refrigeration unit, which often remains unattended until serious problems will begin. It is this elastic contour that ensures the tightness of the chamber, preventing cold air from escaping and warm air from penetrating inside. If you notice that the door does not fit tightly, and condensation or ice has appeared on the inner surface of the glass, then, most likely, seal lost its properties.
Timely replacement of this part with technology LG avoids overloading the compressor and significantly reduces energy consumption. In this article, we will examine in detail how to independently diagnose and replace a worn cuff, without resorting to the services of expensive service centers.
The process of restoring tightness does not require unique engineering skills, but requires accuracy and adherence to a sequence of actions. A correctly installed sealing tape will extend the life of your refrigerator for many years.
Diagnostics of the condition of the seal
Before going to the store for a new part, you need to make sure that the problem lies precisely in the rubber, and not the door is skewed or the hinges are faulty. An initial visual inspection will often reveal obvious defects such as cracks, tears, or areas where the material has become hard and brittle. However, some damage may be microscopic, but break the tightness of the entire system.
One of the most reliable ways to check is a test with a sheet of paper. Take a regular A4 sheet, open the refrigerator door slightly LG and place the paper between the body and the seal. Then close the door and try to pull out the sheet. If the paper is removed freely, without noticeable resistance, it means that in this place the seal is broken.
⚠️ Attention: If the paper is pressed tightly around the entire perimeter, but the cold still goes away, the problem may be in the incorrect position of the refrigerator itself. Make sure that the equipment is level and, if necessary, tighten the adjustable supports.
It is also worth paying attention to the color of the material: if the white rubber is yellowed or covered with black spots of mold, its operation becomes unhygienic. In such cases, even partial restoration of the shape will not help, a complete replacement of the element is required element replacement.
Choosing a suitable seal for the LG model
The spare parts market offers many options, but for equipment LG it is extremely important to choose an original or the highest quality analogue. Seals can differ not only in the length of the perimeter, but also in the cross-sectional profile, as well as in the method of attachment to the door leaf. An incorrectly selected part may simply not fit into the groove or, conversely, dangle.
To find the right spare part, you will need the exact model of your refrigerator. It is usually indicated on a sticker located inside the chamber or on the back wall of the unit. Look for a code that begins with letters GA-, GN- or GC-followed by a set of numbers. It is this code that must be entered into the search bar of the spare parts store.
- 🔍 Original spare parts: They guarantee a perfect match of sizes and colors, but are more expensive and can take longer to deliver.
- 🏭 Quality analogues: Often produced in the same factories as the originals, but under a different brand, which allows save money.
- ⚠️ Universal rubber bands: Require trimming and complex installation, not recommended for beginners, as there is a high risk of breaking the seal.
When ordering, be sure to check the corners: in some models LG they can be reinforced with magnets or shaped. If you are in doubt about the choice, it is better to consult with the seller, providing him with close-up photographs of the old rubber band.
Necessary tools and preparation
Replacing the seal with refrigerator LG is a procedure that does not require complex electrical equipment, but the right set of tools will make the job faster and safer. The bulk of the time will be taken by carefully dismantling the old tape and preparing the surface for the new one.
You will need a flat-head screwdriver, but be careful: a tool that is too sharp can scratch the plastic of the door or damage the new seal during installation. It is best to wrap the screwdriver blade with masking tape or use a plastic spatula, which is often included in electronics repair kits.
Tool list:1. Hair dryer (construction or household hair dryer)
2. Flat-head screwdriver or plastic spatula
3. Degreaser (alcohol or special solution)
4. Lint-free cloth napkin
5. Silicone grease (optional)
It is also critical to prepare the surface. Old glue, grease and dust must be completely removed, otherwise the new elastic band will not fit tightly. Use degreaser for final processing of the channel where the seal will be inserted.
| Tool | Purpose | Importance |
|---|---|---|
| Hair dryer | Heating up hard rubber for elasticity | High |
| Screwdriver | Prying up the edges and fixing in the groove | Medium |
| Degreaser | Removing fat for better adhesion | High |
| Wipe | Surface cleaning | Average |
The process of dismantling the old rubber band
You should start working only after the refrigerator is unplugged and defrosted. Water inside the chambers can interfere with operation, and condensation can impair the adhesion of the new part. Removing the old seal on models LG is usually done by pulling it out of a special mounting groove.
Grip the edge of the seal in one of the upper corners of the door. With a sharp but controlled movement, pull the rubber towards you and down. In most cases, it comes out of the groove along with the plastic profile on which it rests. If the rubber is very old and crumbling, the process may take longer as you will have to clean out the remaining material from the channel.
⚠️ Attention: Do not use metal objects with sharp edges to pick in the groove if pieces of old rubber are stuck there. You can damage the plastic groove of the door, and then it will be impossible to restore the tightness without replacing the entire door.
After removing the tape, carefully inspect the door profile. There should be no foreign objects left on it. If the old seal was attached with glue (which is less common in modern models LG, but possible in older series), the remaining glue must be carefully cut off with a blade and the surface cleaned.
☑️ Preparation for dismantling
Installing a new seal
The most responsible stage is the installation of a new part. Installing the seal on the refrigerator LG requires patience, since the rubber must be evenly distributed around the entire perimeter. It is best to start from the top corner, inserting the profile into the groove and gradually moving down and to the sides.
If the new elastic seems too hard or has creases from the packaging, be sure to use a hair dryer. Heat the material with warm air (do not overheat, so as not to melt the plastic), knead it with your hands and immediately insert it into the groove. This will help straighten the profile and avoid waves.
- 🔨 Fixing the corners: Corners are the most difficult places. Use a plastic spatula to push the profile firmly into the groove. Make sure that the magnetic strip inside the rubber has not turned out.
- 📏 Uniformity: Move around the perimeter, checking that the seal does not puff up anywhere and does not go deep inside. It should stand exactly in one plane.
- 🧪 Final check: After installation, run your hand along the entire contour to make sure there are no gaps.
Some models may require additional fixation with screws. If your design has holes for fastening under the elastic, tighten them after complete installation, but do not overtighten so as not to push through the plastic.
What to do if the elastic is longer than necessary?
If you bought a universal seal or made a mistake with the size and it turned out to be longer, it can be carefully trimmed in the lower corner (usually from the hinge side). However, for original parts LG this is not required - they have exact dimensions. It is better to compensate for the excess length by a tighter fit in the corners, warming it with a hairdryer.
Final adjustment and tightness check
After the new rubber band is installed, do not immediately load the refrigerator with food. Give the material time to “rest” and take its final form. Plug in the unit and leave it idle for 2-3 hours. During this time, the magnets in the seal will heat up from the operation of the compressor and finally stick to the metal of the body.
Carry out a repeat test with a sheet of paper around the entire perimeter of the door. Now the sheet should be removed with noticeable force everywhere. Also visually assess the gap: it should be minimal and uniform. If you see that the door is moving away in some place, the hinges may need to be adjusted.
To improve sliding and extend the service life of the rubber, you can lubricate it with a special silicone lubricant. This will prevent the material from drying out and cracking in the future. Remember that the use of edible oils (sunflower, olive) is strictly prohibited - they will ruin the rubber.
Regularly check the condition of the seal and wipe it with a soft damp cloth. Caring for this part is simple, but it is what allows you to avoid serious damage to the refrigeration system in the future.
Is it possible to glue a torn rubber band back?
A temporary solution is possible using a special glue for rubber or sealant, but this does not guarantee durability. The glue will dry out over time and the seal will break again. It is better to replace the part completely.
How often should the seal be changed?
The service life of a high-quality seal is 5–7 years. However, with intensive use or improper care (aggressive chemicals), it may become unusable sooner.
Why does a new rubber band smell?
The smell of new rubber is normal. It should dissipate within a few days of running the refrigerator. To speed up the process, you can wipe it with a solution of citric acid.
