One of the most common reasons for temperature violations in the refrigerator compartment is damaged or worn on the door seal. If you notice that LG refrigerator it has become louder than usual, ice is freezing on the back wall, or food has begun to spoil faster, the problem most likely lies in the loose fit of the sash. Replacing the seal is a procedure that you can do yourself, saving on calling a technician and restoring the seal of the chamber.
Modern models, such as LG No Frost or LG DoorCooling, use a special magnetic tape that ensures a tight pressing the door against the body. Over time rubber band loses elasticity, cracks or deforms, letting warm air inside. Ignoring this defect leads to constant operation of the compressor, increased energy consumption and rapid failure of expensive components of the unit.
In this article we will look in detail at how to correctly diagnose the malfunction, select the appropriate spare part and replace the seal with your own hands. You will learn about the intricacies of installation on various types of fasteners and how to avoid typical mistakes that inexperienced users make when servicing household appliances.
Diagnostics of the condition of the seal
Before you go to the store for spare parts, you need to make sure that the problem is really in the seal, and not in a skewed door or a malfunction of the thermostat. An initial visual inspection often reveals obvious defects: cracks, tears or areas where magnetic tape has completely lost its properties. However, microcracks or uneven sealing may not be immediately noticeable.
There is a simple and effective way to test for tightness, known as the “sheet of paper test”. Take a regular A4 sheet and place it alternately between the body and the seal around the entire perimeter of the closed door. If the leaf is removed easily, without noticeable resistance, it means that in this place LG seal does not provide proper tightness.
⚠️ Attention: If a gap is found in only one place, perhaps the matter is not in the wear of the rubber, but in the misalignment of the door hinges. In this case, replacing the seal will not work - you will need to adjust the canopies.
It is also worth paying attention to the condition of the rubber itself. If it has become hard, “oaky” to the touch or is covered with small cracks, it is no longer possible to restore its former elasticity. In such cases replacing the seal is the only correct solution for normal operation of the refrigerator.
Choosing a suitable seal for the LG model
Refrigerators of the South Korean company LG are produced in a huge number of modifications, and there are no universal rubber bands for them. Each series, be it LG GA-B, LG GC-B or built-in models, has its own unique seal profile. Trying to install the wrong part will result in the door not closing or closing with force, damaging the mechanism.
To find the right spare part, you need to know the exact model of your unit. Usually the marking plate is located on the inner wall of the camera or on the rear panel. You need to look for a code starting with letters GA, GC, GR or GS. It is this code that needs to be entered into the search when ordering the original seal.
There are also compatible analogues on the market, which are often cheaper than the originals. They can be made of rubber of a different density. If you choose an analogue, make sure that the section profile (cross-section shape) completely matches the original. Even a millimeter discrepancy can disrupt the operation of the magnetic valve.
| Seal type | Compatibility | Installation features | Service life |
|---|---|---|---|
| Original LG | Ideal for a specific model | Exact match of angles | 7-10 years |
| Universal (for cutting) | Requires trimming | Complicated, necessary experience | 3-5 years |
| Compatible analogue | For groups of models | Adjustment possible | 4-6 years |
| Refurbished | Depends on quality | Standard | 1-2 years |
Where to look for the article number?
The article is often stamped directly on the inside of the seal itself. To see it, carefully bend the edge of the elastic at the bottom corner of the door. There may be a code starting with numbers, for example, 400 or 500, followed by an alphanumeric combination.
Necessary tools and preparation
The replacement process does not require complex professional equipment, but having the right tool will greatly simplify the task and protect the door plastic from damage. You don't need heavy power tools, but you should have a set of basic tools on hand for careful work on delicate surfaces.
First of all, prepare a hair dryer. This can be an ordinary household hair dryer, but it must have a temperature control function. Hot air Necessary for softening the new rubber so that it fits into place easier, as well as for straightening creases that form during transportation of a new spare part.
Also for you you will need:
- 🔧 A screwdriver with a flat or Phillips blade (depending on the type of screws in your model).
- 🧤 Fabric gloves to protect your hands and prevent tools from slipping.
- 🧼 Soap solution or silicone grease to facilitate sliding when installation.
- 📏 Level or ruler to check the evenness of the door installation.
⚠️ Attention: Do not use sharp metal objects (knives, thin-blade screwdrivers) to pry the seal unless absolutely necessary. It is very easy for them to damage the plastic groove of the door or break through the rubber itself, which will make further sealing impossible.
Before starting work, be sure to disconnect the refrigerator from the power supply. This safety rule applies to any procedure related to the disassembly or maintenance of electrical appliances, even if you do not touch the internal electrical components.
Removing the old seal
Removing the old seal is a process that requires care, but not haste. In most refrigerator models LG the seal is attached in two ways: either inserted into a special groove around the perimeter of the door, or additionally fixed with screws in the corners. You can determine the type of fastening by carefully examining the corner joints.
If you find screws, they need to be unscrewed. Usually they are hidden under decorative plugs or located directly at the end of the seal. After removing the fasteners, you can begin to remove the rubber band from the groove. This must be done evenly, starting from one of the upper corners.
Procedure for dismantling:
- 🛑 Pull the edge of the seal from the door body to release the fastening profile.
- 🛑 Move slowly along the perimeter, removing the seal from the groove hands.
- 🛑 If the rubber is stuck or dirty, carefully pry it off with a plastic spatula.
When removing it, try not to smear dirt on the clean groove of the door. After removal, immediately wipe the exposed surface with a damp cloth and detergent to remove any remaining adhesive, grease and dust. The cleanliness of the groove is the key to a tight fit of the new part.
☑️ Preparation for installation
Installation and installation of a new seal
Installing a new seal is the most critical stage. New tires are often stiffer than old ones and may have creases from packaging. Before installation, it is recommended to heat the new tape with a hairdryer at medium temperature to make it more elastic and soft. This will make it easier to insert the profile into the groove.
It is best to start installation from the top corner of the door. Insert the seal profile into the groove, making sure it is seated deep and level. Then, gradually moving down and to the sides, tuck the rubber around the entire perimeter. The movements should be confident, but smooth, so as not to stretch the material unevenly.
In the corners where the seal profile has a thickening or bend, apply a little more force. If your model is screw-fastened, do not tighten the screws all the way in right away. First, attach them in all corners, check the tightness of the fit, and only then tighten them completely.
⚠️ Attention: Do not stretch the seal during installation! If the rubber is stretched, it will begin to shrink over time, and cracks will form in the corners of the door through which the cold will escape. The seal should lie in the groove freely, without tension.
After the entire tape is installed around the perimeter, run the hair dryer again along the entire door, warming up the rubber. This will help it finally straighten and take the desired shape. The door may close a little tightly in the first few days - this is normal until magnetic layer it develops.
Quality check and alignment
After installation, a final check must be carried out. Use the paper sheet method again that you used for the diagnosis. Walk around the entire perimeter: the sheet should be pulled out with force, but not torn. If in some place the paper slips too easily, it means that the seal is not completely seated or has a defect.
Often after replacement, users are faced with the fact that the refrigerator door LG began to not close completely or, on the contrary, requires a strong clap. This may indicate that the new seal is thicker than the old one. In this case, it may be necessary to adjust the door hinges.
For adjustment, you usually need to:
- 🔧 Remove the decorative trim from the hinge.
- 🔧 Loosen the mounting bolts with a wrench.
- 🔧 Slightly move the door in the desired direction.
- 🔧 Tighten the bolts and check the result.
It is also worth checking whether the new seal does not touch the shelves or products inside the chamber. Sometimes an increase in the volume of rubber can lead to the fact that it begins to touch the internal elements when closing, which prevents airtight closure.
Frequent errors and recommendations
When replacing a seal on your own, even experienced craftsmen sometimes make mistakes that negate all the work. One of the most common is the use of glue. Remember: refrigerator seals LG are attached mechanically, in a groove or with screws. Use of glue (superglue, instant glue) is unacceptable, as it destroys the structure of rubber and plastic, making it impossible to re-replace without damaging the door.
Another mistake is ignoring the temperature conditions during installation. If you install the seal in a cold room or in the frost, the rubber will be too hard and may crack when bent. It is better to carry out work at room temperature, and it is advisable to keep the new part itself in a warm room for at least 2-3 hours before installation.
Do not forget about cleanliness. Dust or crumbs caught between the rubber and the body can create a micro-gap that will allow air to pass through. Clean the groove thoroughly before installation. Also, do not forget to regularly (once every six months) wash the seal with soapy water and lubricate it with silicone to prevent drying out.
How often should the seal be changed?
The average service life of a high-quality seal is 7-10 years. However, with intensive use, frequent opening of the door or unfavorable conditions (high humidity, temperature), replacement may be required earlier, after 4-5 years. The main indicator is loss of tightness.
Is it possible to restore an old seal?
There are traditional methods, for example, soaking in boiling water or treating with glycerin. They can temporarily restore elasticity if the rubber has simply become stiff from the cold. But if there are cracks or breaks, restoration is impossible - only replacement.
Why does the new seal smell?
New rubber always has a specific smell, which is the norm. It should air out within 1-2 weeks after installation. To speed up the process, you can wipe the seal with a weak solution of vinegar or citric acid.
What to do if the corners do not fit?
If the corners do not fit immediately, use a hair dryer to heat the problem area and press firmly with your hand until it cools. You can also leave the door closed for several hours (you can even fix it with tape, but carefully) so that the rubber “remembers” the desired shape.
Does replacing the seal affect the warranty?
Independent replacement of consumables, such as seals, usually does not void the warranty on the main components (compressor, electronics), unless other parts were damaged during the replacement process. However, if you damage the door or hinges, the warranty claim may not be accepted.
