The situation when the sealing rubber on the door of an LG refrigerator begins to come off or loses elasticity is familiar to many owners of this equipment. It is this element that is responsible for the tightness of the chamber, keeping the cold inside and keeping the heat out. If you notice that the door begins to close loosely or condensation has formed in the corners, most likely it’s time to service or replace the sealing contour sealing contour.
You can remove the rubber band from the LG refrigerator yourself, without resorting to the services of a service center, if you act carefully and know the design features of the fastening. Modern models of the Korean brand use several types of fixation, and it is important to determine your case before starting work. Incorrect actions can lead to damage to the plastic of the door or the seal itself, so carefully study the design of your unit.
In this article we will analyze all the nuances of dismantling, cleaning and reinstalling the element so that your refrigerator works in optimal mode again. You will learn how to distinguish a magnetic type of fastening from a mechanical one, what tools you will need and how to avoid common mistakes. Proper care will extend the life of the equipment and save energy.
Diagnostics of the condition of the seal
Before proceeding with active removal actions, it is necessary to assess the current condition of the rubber. Often the problem lies not in the physical wear of the material, but in contamination or deformation, which can be eliminated without replacement. Carefully inspect seal along the entire perimeter of the door, paying attention to the corners and folds.
If the rubber is simply dirty, it may not fit tightly to the body due to adhering fat or crumbs. In this case, deep cleaning will return it to its original functionality. However, if cracks, tears, or the material has become hard and brittle are visible on the surface, then removal is necessary to replace the part.
⚠️ Attention: If the seal has visible mechanical damage (cuts, holes), its restoration is impossible - a complete replacement with a new original is required.
Check the magnetic properties throughout length To do this, close the door on a piece of paper and try to pull it out. If the paper comes out easily in different places, it means that the magnetic tape inside the rubber has weakened or come off. This is a direct signal that tightness is broken and the compressor is working with increased load.
Necessary tools and preparation
To do the job of removing the rubber band from the LG refrigerator efficiently, you will need a minimum set of tools. The main requirement is that the tools should not have sharp edges that could scratch the plastic surface of the door or damage the rubber itself if you plan to remove it and install it back.
First of all, prepare a flat-head screwdriver with a wide blade, but be sure to wrap its working end with electrical tape or masking tape. This will protect the plastic from scratches. You may also need a hairdryer to heat up the material if the rubber has hardened in the cold or from time to time.
☑️ Tools for replacing the seal
Prepare the workplace in advance. Clear some space in front of the refrigerator so you can access the door from all sides. If the model allows, it is better to remove the door and place it on a flat surface covered with a soft blanket, but you can often get by with the unit in a vertical position.
Types of fastening of seals in LG refrigerators
Understanding the type of fastening is a key point on which the algorithm of your actions depends. LG engineers use different fixation systems depending on the year of manufacture and series of the refrigerator. An error in determining the type can lead to breakage of fasteners.
The first and most common option is fastening into a groove (groove). In this case, the rubber has a special protrusion that is tightly inserted into the groove at the end of the door. It is held in place by friction and the shape of the profile. It is removed by pulling it out of the groove along the entire perimeter.
The second option is a screw fastening. Here, the sealing rubber is pressed against the door with a plastic strip or metal strip, which, in turn, is screwed with self-tapping screws. Such screws are often hidden under decorative plugs or the rubber itself. To access them, a partial or complete bend of the seal is required.
How to distinguish the type of fastening without disassembling?
Carefully inspect the inner corner of the seal. If you see a series of holes or indentations along the entire length hidden under the elastic, it is a screw type. If the rubber is simply inserted into the slot without visible holes, this is a groove fastening.
The third, rarer for modern models, but found in older series, is a combined type. It combines gluing in the corners and mechanical fastening in the middle of the sides. In such cases, special care is required and, possibly, heating of the adhesive.
Step-by-step process of removing the gum
The dismantling process depends on the identified type of fastening, but always begins with preparation. If you determine that you have a mortise mount, start at any top corner. Carefully bend the edge of the seal and pull it towards you and to the side, removing it from the groove.
Move gradually, freeing 10-15 centimeters of the contour at a time. Do not pull sharply so as not to stretch the rubber unevenly. If the rubber fits very tightly, you can slightly help yourself with a flat object (for example, a plastic card or a dull knife), prying the edge out of the groove.
In the case of a screw fastening, the algorithm is more complicated. You need to find where the screws are attached. Often they are located under the rubber itself. Carefully bend the seal at the intended fastening points to get to the screw heads. Use an appropriately sized screwdriver (usually Phillips PH2 or flathead) to remove them.
After unscrewing all the screws (there can be from 8 to 12 around the perimeter), remove the clamping bar and the rubber itself. Be careful: the screws may be different lengths, so arrange them in the order they are removed or label the installation locations.
⚠️ Attention: When removing a screw-mounted seal, do not lose any washers or bushings that may be located under the screws. They provide the correct pressure.
Cleaning and maintaining the removed seal
If you have removed the elastic for cleaning or maintenance, this is an excellent time for deep care. Even if you plan to replace the seal, cleaning the seat on the door is mandatory. Mold, grease and dirt often accumulate there and interfere with a tight seal.
Wash the removed rubber with warm water and a mild detergent. Use a soft sponge, avoiding abrasive materials. Pay special attention to folds and the inner profile, where moisture likes to stagnate. After washing, carefully wipe the part dry.
The landing groove on the door also requires processing. Wipe it with an alcohol solution or a special degreasing agent. This will improve grip and provide a tighter fit when reinstalled. Make sure that there is no debris or old glue left in the groove.
To restore the elasticity of old but intact rubber, you can use silicone grease. It will prevent the material from drying out in the future. Apply a thin layer of lubricant to the surface that is in contact with the refrigerator body.
Installing a new or cleaned seal
Installation is carried out in the reverse order of removal. If you have a groove mount, start at the top corner. Insert the edge of the seal into the groove and gradually, ironing it with your hand, tuck it around the entire perimeter. The movements must be confident so that the rubber sits all the way.
For screw fastening, first install the rubber in place, then press it with a bar and tighten the screws. Do not over-tighten the screws at once. First tighten all the screws halfway to level the position, and then finally tighten them diagonally to ensure even pressure.
After installation, be sure to check the quality of installation. Run your hand along the entire perimeter, making sure there are no bulges or gaps. The door should close with a characteristic sound, but without excessive force.
| Problem type | Possible cause | Solution method |
|---|---|---|
| Door does not fit tightly | Contamination or misalignment | Cleaning the seal and adjusting the hinges |
| Rubber falls out of the groove | Stretching or wear | Replacing the seal or shortening (professional) |
| A whistle is heard when closing | The fit is too tight | Lubricate with silicone or check the installation level |
| Ice forms in the corners | Tightness is broken | Checking the magnetic tape and the integrity of the rubber |
Frequent errors during replacement and their consequences
Inexperienced craftsmen often make mistakes that lead to all efforts are in vain. One of the most common is using the wrong cleaning chemicals. Aggressive chemicals can corrode the rubber, making it sticky or brittle.
Another mistake is the incorrect sequence of tightening the screws. If you twist them in any order, a skew may form and a gap will remain in one of the corners. Always move from the center outwards or diagonally.
Ignoring the heat of the rubber when installing in a cold room is another risk. Cold rubber is hard and can crack when bent. Let the new seal sit at room temperature for several hours before installation.
⚠️ Attention: Technical characteristics and designs of LG refrigerators may vary in different modifications. Before starting work, check the instructions for your specific model, as the location of the screws or the shape of the groove may differ.
FAQ: Frequently Asked Questions
Is it possible to glue a torn rubber band with regular glue?
It is not recommended to use regular superglue or Moment glue, as they make the rubber hard and can destroy its structure. To repair small areas, it is better to use special glue for rubber or silicone sealant, but a complete replacement will be more reliable.
How often do you need to change the seal on an LG refrigerator?
The service life of the seal is on average 5-7 years. However, with intensive use or aggressive cleaning with chemicals, it may become unusable sooner. Change it as cracks appear or loss of tightness.
Why may the new seal not fit immediately?
New rubber often has shape memory (twisted into a ring when packaging) and may be stiffer than the old one. She needs time (from 2 to 5 days) to straighten and take the desired shape. You can speed up the process by gently warming up problem areas with a hairdryer.
Where can I find the original seal for my model?
Original spare parts can be found by the service number (P-number) on the sticker inside the refrigerator compartment or on the website of an official LG representative. Specify the exact model when ordering, since even elastic bands that are similar in appearance may differ in size.
