A decrease in the efficiency of refrigeration equipment is often associated with banal wear of the sealing elements. If you notice that refrigerator door it has begun to fit less tightly or ice has begun to accumulate inside the camera, most likely the magnetic tape is to blame. In refrigerators LG this part loses elasticity over time, cracks or deforms, ceasing to perform its barrier function.
Timely replacement of the rubber band on the refrigerator LG avoids more serious damage, such as failure compressor due to constant operation. The process of restoring tightness does not require specialized engineering education, but it does require accuracy and understanding of the design of a particular unit. In this article, we will analyze in detail how to independently diagnose and replace the seal, returning the equipment to factory efficiency.
The main rule before starting any work is to complete shutdown the unit from the mains. Even if you think that replacing the rubber band does not affect the electrical components, safety should be a priority. This will eliminate the risk of an accidental short circuit or electric shock in the event of damage to the insulation of wires hidden in the door leaf.
Diagnostics of the condition of the seal
Before going to the store for spare parts, you need to make sure that the problem lies precisely in the rubber band, and not in skewed hinges. Visual inspection seal often reveals obvious defects: cracks, abrasions, tears or areas where the magnetic insert can be felt unevenly. If the rubber has become hard and does not restore its shape after pressing, its resource has been exhausted.
There is a simple and effective way to check the tightness, known as the “sheet of paper test”. Take a regular A4 sheet, clamp it with the refrigerator door so that part protrudes out, and try to pull it out. If the sheet is pulled out easily and without resistance along the entire perimeter, it means that magnetic clamp is weakened.
⚠️ Attention: If a sheet of paper is held tightly at the top of the door, but easily slips out at the bottom (or vice versa), the problem may not be in the rubber, but in the misalignment of the door canvases. In this case, first try adjusting the position of the door.
You should also pay attention to the condition of the groove into which the seal is inserted. In models LG over time, mold or grease may accumulate there, which destroy the structure of the rubber. Sometimes deep cleaning and silicone treatment can temporarily extend the life of a part, but if there is mechanical damage, only replacing the seal will help.
Choosing a suitable seal model
The market for spare parts for household appliances offers many options, but LG it is critically important to choose an original profile or a high-quality analogue with exact geometric parameters. Seals differ not only in the length of the sides, but also in the cross-sectional shape, type of fastening (in a groove or with screws) and the strength of the magnetic field. An incorrectly selected rubber band may not fit into mounting groove or leave gaps.
To find the right part, you need to know the exact model of your refrigerator. This information is usually indicated on a label located inside the camera or on the back wall. Look for a code starting with letters GA, GB or GC. Using this code you can find an original spare part or a compatible analogue.
When choosing between an original and a replica, several factors should be taken into account. Original seals LG last longer and hold the temperature better, but are more expensive. High-quality analogues may be cheaper, but require more careful adjustment during installation. Cheap Chinese copies often have a weak magnet and an unpleasant odor that does not disappear for a long time.
Where to look for the article number?
The article number is usually printed on the inside of the seal itself in the form of a stamp. If the rubber band is severely damaged, look for the number on the packaging from the previous replacement or in the technical documentation for the refrigerator model.
Necessary tools and preparation
To successfully replace the rubber band on the refrigerator LG you do not need a complex professional tool. However, preparing the workplace and having all the necessary items on hand will significantly speed up the process and reduce the risk of damage to the plastic elements of the door. The main tool will be a flat-head screwdriver, but it should not be too sharp so as not to scratch the plastic.
You will also need a hair dryer to straighten the new elastic band, since it often becomes deformed during transportation. If you don’t have a hair dryer, a regular household hair dryer at maximum power will do, although it will take longer to heat up. To fix the elements, you may need electrical tape or masking tape.
☑️ Tools for replacement
Free up space in front of the refrigerator in advance. The door will have to be opened wide and, perhaps, shelves removed to gain access to the ends. Make sure that you have good lighting, as mounting profile often has a dark color, and in the twilight it is easy to miss an installation defect.
Removing the old seal
The process of removing the old rubber band depends on the type of fastening installed in your models LG. Most modern refrigerators use a dovetail fastening system, where the seal is simply inserted into a special groove around the perimeter of the door. In older or specific models, the elastic band can be additionally secured with screws.
Start dismantling from one of the upper corners. Gently pry the edge of the seal with a flathead screwdriver or your fingers and pull it towards you. Movements should be confident, but without jerking, so as not to damage the plastic door body. If you feel strong resistance, check for hidden screws under the decorative plugs.
⚠️ Attention: Be careful when removing the seal. Old rubber may crumble, leaving pieces in the groove. All remnants of old glue or rubber must be carefully removed before installing the new part, otherwise the seal will be compromised.
After the main circuit is removed, inspect the corner joints. In some designs, the corners can be additionally fastened. Thoroughly clean the entire perimeter of the channel from dirt, grease and old material residues. To do this, you can use a soft brush and soap solution, after which the surface must be wiped dry.
Installing a new seal
Before installing the new rubber, it is recommended to warm it up with a hairdryer. This will make the material more elastic and allow it to more easily take the desired shape. Start installation from the top corner, inserting the profile part of the seal into mounting groove the doors. Make sure that the dovetail is securely latched.
Move sequentially around the perimeter, first securing the long sides, and then moving on to the short ones. In the corners of the door leaf, the elastic must be placed especially carefully, forming a neat joint. Do not stretch the seal too much so that it does not become thin and lose its magnetic properties in critical places.
If your model has screws for fixation, tighten them after inserting the rubber into the groove. Do not overtighten the screws to avoid pushing through the plastic. After complete installation, walk your hand around the entire perimeter, checking the tightness of the fit. The seal should fit tightly, without gaps between it and the door body.
Final adjustment and check
After installing a new seal, the door may close tightly or not completely due to the fact that the rubber has not yet straightened out. To correct the situation, use a hairdryer: heat the problem areas and press the door tightly, locking it in the closed position for 15-20 minutes. You can use masking tape or straps to ensure a tight fit. surface contact.
Be sure to repeat the test with a sheet of paper around the entire perimeter. The resistance should now be felt evenly. Also check the operation of the open door alarm - it should work correctly, since the new magnet can hold on stronger.
On the first day after replacement, it is recommended not to completely load the refrigerator with food so that the seal is finally formed at operating temperature. Periodically check the formation of condensation or ice during the first weeks of operation.
Comparison of types of seal fastenings
Understanding the differences in types of fastenings will help you avoid mistakes when purchasing and installing. In refrigerators LG there are various design solutions, and knowing their features will save you time.

Frequently asked questions (FAQ)
Is it possible to restore an old rubber band instead of replacing it?
You can temporarily extend the life of the seal if it is intact, but has lost its elasticity. Treatment with silicone grease or heating with a hairdryer and then closing the door tightly will help. However, if there are cracks or breaks, restoration is impossible - only replacing the seal.
How long does a new seal on an LG refrigerator last?
The service life of a high-quality original seal is on average 5-7 years with proper use. Regular washing and the absence of aggressive chemicals help preserve the properties of rubber longer.
Why did the door begin to close tighter after replacement?
This is normal for a new part. The new rubber is more resilient, and magnetic tape has not yet been developed. After 2-3 days of active use magnetic clamp it will weaken to working condition, and the door will close easier.
Do you need to lubricate the new seal?
It is not necessary to lubricate the new rubber, but you can wipe it with a weak one glycerin solution or special silicone grease for rubber. This will prevent drying out and cracking in the first months of use.
