The appearance of condensation on the inner walls of the chamber or extraneous noise when closing the door often indicates a leak in the seal. In refrigerators of the brand LG a special magnetic tape hidden inside the elastic cuff is responsible for the tight fit of the doors. Over time, rubber loses its ductility, cracks or deforms, ceasing to perform its function.
Independent replacement of this element is a completely solvable task for a home craftsman that does not require complex professional equipment. Critical important understand that ignoring the problem will lead to overload of the compressor and damage to food. In this material we will analyze all the nuances of dismantling the old part and installing a new one.
Diagnostics of the condition of the sealing gum
Before you start purchasing spare parts, you need to make sure that the problem lies precisely in the wear of the seal. Often, users mistakenly blame the door design itself for leaks, when simple cleaning or adjusting the hinges is sufficient. A visual inspection should reveal obvious mechanical damage: cracks, tears or “hardened” areas.
There is a simple and effective method for checking the tightness of the seal, known as the “paper test”. You will need a regular A4 sheet. Squeeze it between the refrigerator body and the door, then try to pull it out. If the sheet is removed freely, without noticeable resistance, it means that in this place the seal is broken.
Particular attention should be paid to the corner areas and places around the door handle, where wear occurs the fastest. If the rubber is simply dirty, you can try to restore it, but if there are deep cracks, only replacement will help.
- 🔍 Run your finger along the entire length of the tape, looking for hidden tears.
- 📄 Use a test with a sheet of paper at different points of the perimeter.
- 👀 Inspect the surface for mold or black deposits.
⚠️ Attention: If the seal has simply moved away from the groove in several places, but the rubber itself is intact, you may be able to do without replacement by simply pushing it into place after heating.
Do not ignore even small gaps. Loss of cold forces the compressor to work non-stop, which shortens the service life of the unit LG and increases electricity bills.
Choosing the appropriate seal model
The spare parts market for household appliances is crowded suggestions, but LG it is important to choose an original or high-quality analogue. Seals differ not only in size, but also in cross-sectional profile, as well as in the method of fastening. An incorrectly selected part may not fit into the groove or may have a too weak magnetic field.
The ideal option is to search for a spare part using the serial number of your refrigerator. This code is usually located on a sticker inside the camera or on the back wall. Knowing the exact model, for example LG GA-B409 or LG DoorCooling+, you can find a compatible article in the manufacturers' catalogs.
When choosing between the original and the universal model, remember: universal tapes often require cutting corners or gluing, which reduces the reliability of the design. Factory seal already has the required length and the shape of the corners.
⚠️ Attention: Technical characteristics of the seals may vary depending on the year of manufacture of the model. Always check the part number with the data in the official spare parts catalog LG before purchasing.
Pay attention to the material: high-quality rubber should be soft and elastic even at room temperature. Hard rubber will quickly lose its shape, and the seal will be broken again.
Necessary tools and preparation
Sophisticated tools are not required for successful work, but preparation of the workplace is required. You will need free space in front of the refrigerator, since the door will have to be removed or swung wide open. Empty the shelves on the door in advance to reduce the load on the hinges during dismantling.
The basic set of tools includes several items that can be found in any home. The main thing is to ensure good lighting of the working area in order to see the groove profile and fasteners.
- 🔧 Screwdriver (Phillips or flat) for removing decorative panels.
- ✂️ A dull knife or plastic spatula for prying up the tape.
- 🧼 Cleaning agent and degreaser for surface preparation.
- 🌡️ Hair dryer (construction or household) to soften new rubber.
Prepare a container with warm water in advance. It will be useful for straightening out creases on the new seal before installation. Surface cleanliness is the key to the durability of the installation, so remove all remnants of old glue or dirt.
☑️ Preparation for replacing the seal
Removing the old seal
The process of removing the old tape depends on the type of fastening used by the manufacturer. In modern models LG most often, a seal is inserted into a special groove on the inner plastic door panel. Fastening with self-tapping screws through a decorative strip is less common.
If your model involves fastening through a strip, carefully unscrew the screws around the perimeter of the door. Be careful not to damage the plastic. After removing the strip, the old seal can be easily removed. If the rubber is simply inserted into the groove, start pulling it from the corner, gradually releasing it from the channel.
In some cases, the rubber may “stick” to the plastic. Do not use sharp metal objects to avoid scratching the door. It is better to use a plastic spatula or a dull knife.
After removal, carefully inspect the plastic door panel. There should be no pieces of old rubber or glue left on it. Rinse thoroughly and degrease the surface.
⚠️ Attention: When dismantling, do not apply excessive force to the door itself so as not to disturb the geometry of the hinges. If the tape fits very tightly, heat it with a hairdryer.
What to do if the seal is glued?
In rare cases, especially after unqualified repairs, the seal may be stuck to the glue. In this case, heat the tape with a hairdryer and slowly cut it off with a blade, being careful not to damage the plastic of the door. The remaining adhesive is removed with a solvent.
Technology for installing a new seal
Before installation, it is recommended to warm up the new seal. This can be done by immersing it in warm water (about 50-60 degrees) for 10-15 minutes or gently warming it with a hairdryer. Elasticity the material will increase significantly, which will facilitate installation and straighten out possible creases from storage.
Start installation from the top corner. Insert the corner of the seal into the groove, making sure it fits snugly. Then, moving along the side, tuck the profile into the channel. Use a blunt instrument or your fingers to push the mounting shelf inward.
Pay special attention to the corners. This is where cracks most often form if the rubber is stretched or, conversely, assembled like an accordion. Try to distribute the material evenly.
Comparison of installation methods:
| Parameter | Insertion into a groove | Fixing with a strip | On glue |
|---|---|---|---|
| Complexity | Average | Low | High |
| Installation time | 30-40 min | 15-20 min | 1-2 hours |
| Reliability | High | Average | Depends on the glue |
| Typical for | Most LG | Old models | Non-standard cases |
If you are using a universal seal that is longer than required, cut off the excess in the lower corner at an angle of 45 degrees for joining.
Adjustment and checking the result
After installing a new element, the door may be difficult to close due to the volume of new, not yet crushed rubber. This is a normal situation. Give the seal time to “shrink,” usually it takes from several hours to a day.
Check the operation of the lock and the tightness of the seal again using the method with a sheet of paper. The door should close with a characteristic bang, but without excessive force. If distortions are noticeable, the door hinges may need to be adjusted.
Turn on the refrigerator and let it operate as normal. After a few hours, check the temperature inside the chamber - it should correspond to the set values.
How often do you need to change the seal on the refrigerator?
The service life of the seal is on average 5-7 years. However, if the refrigerator is in a kitchen with a high temperature or is subject to frequent mechanical stress, a replacement can be made earlier.
Is it possible to glue an old seal?
Using glue to repair an old seal is a temporary and ineffective solution. The glue makes the rubber hard, which breaks the seal. It is better to replace the element immediately.
Why does the new seal not fit?
New rubber often has residual deformation from the packaging. It must be straightened with heat (hairdryer or warm water) and given time to straighten with the door closed.
Where can you find the model number of an LG refrigerator?
The nameplate with the model and serial number is usually located on the inner side wall of the refrigerator compartment or on the rear metal panel of the unit.
