A decrease in cooling efficiency, the appearance of ice or uncharacteristic humming often indicates a violation of the chamber seal. In most cases, the culprit is a worn-out one, which no longer fits tightly to the body. Many equipment owners immediately plan to purchase a new part, forgetting that sometimes the problem can be solved by deep cleaning or proper reinstallation of the old cuff. sealing rubber, which no longer fits tightly to the body. Many equipment owners immediately plan to purchase a new part, forgetting that sometimes the problem can be solved by deep cleaning or proper reinstallation of the old cuff.
The dismantling procedure does not require calling a technician and special expensive tools, but it requires care so as not to damage the door. Incorrect actions can lead to deformation of the plastic or disruption of the door geometry, which will lead to more complex repairs. In this article we will look in detail at how to properly remove the seal, assess its condition and prepare the surface for further work.
Before taking active steps, you need to determine the type of cuff mounting on your refrigerator model. The design may vary significantly depending on the brand and year of manufacture of the equipment. Understanding the structure of the unit is half the success, since the use of force where a lever is needed is unacceptable.
⚠️ Attention: Before starting any work, be sure to disconnect the refrigerator from the power supply. Although the risk of electric shock when removing rubber is minimal, working with electrical appliances requires compliance with basic safety precautions.
Diagnostics of the condition of the seal
The first step should always be a thorough visual and tactile inspection. Users often confuse contamination or displacement of the seal with its physical wear. If the rubber has simply jumped out of the groove or is covered with a sticky coating, its removal may not be necessary - proper installation and washing will be enough.
Pay attention to elasticity of the material. Old rubber often hardens, cracks or loses its magnetic properties. If, when pressed with a finger, creases remain on the surface that do not straighten out for a long time, or microcracks are visible, then it is better to replace the part. Otherwise, you can try to restore the tightness.
There is a simple test to check the tightness without removing the part. Take a thin sheet of paper or a banknote and clamp it around the perimeter of the door. If the paper is easily pulled out or falls out by itself, then the seal is broken. This method helps to localize the problem area.
In some cases, the cause of a loose fit is not the rubber itself, but a skewed door or loose hinges. Before removing the seal, make sure that the door geometry is not damaged. If the door is skewed, replacing the seal will not give the desired result.
Necessary tools and preparation
To do the job well, you will need a minimum set of tools, which can be found in every home. The main requirement for tools is that they should not have sharp edges that can scratch plastic or cut rubber. The use of knives and screwdrivers with sharp tips is strictly not recommended.
You will need the following items:
- 🧤 Gloves — to protect your hands from dust, mold and dirt that accumulate behind the seal.
- 🔦 Flashlight — for inspecting hidden cavities and fastening angles.
- 🧼 A rag and detergent —for preliminary cleaning of the surface.
- 🔧 Plastic shovel or an old bank card—for prying up the edges without damage.
Particular attention should be paid to the workplace. Make sure the area around the refrigerator is well lit. If you are working with heavy Side-by-Side models, you may need an assistant to hold the door while you handle it, as removing the seal may temporarily upset the balance.
Prepare a container of warm water and a mild soap solution. This is useful not only for cleaning, but also for washing tools during the process. Cleanliness is the key to the fact that you will notice all minor defects and fastenings.
Determining the type of cuff fastening
The method of fixing the seal directly affects the algorithm of your actions. Manufacturers use several basic fastening options, and incorrect identification of the type can lead to damage to the part. Carefully examine the inside of the door, where the rubber meets the body.
The most common types of fastenings:
- 📌 Insertion into the groove (groove) —the rubber has a special profile (“herringbone” or “harpoon”), which is tightly inserted into the groove on the door. It is removed by pulling.
- 🔩 Fastening with self-tapping screws —the sealing tape is pressed against the door with a metal or plastic strip, which is screwed on. Often found in older models.
- 🧲 Magnetic tape inside the profile —the seal itself can be removable, but the magnetic insert is hidden inside the rubber. In rare cases, the magnet is attached separately.
If you see a row of screws around the perimeter of the inside of the door, hidden under a decorative strip or directly pressing the rubber, you will need a Phillips screwdriver. In the case of a grooved connection, a screwdriver is not needed; the effort of your hands and a plastic tool is enough.
⚠️ Attention: In models with self-tapping screws, the screws can be hidden under decorative plugs or stickers. Carefully inspect the perimeter so as not to miss hidden fasteners.
Modern refrigerators are characterized by combined fastening or the use of complex profiles. If you are not sure about the type of fastening of your model Indesit or LG, it is better to find technical documentation or photos of a similar model on the Internet before starting work.
Technology for removing a seal with groove fastening
The most common option in modern technology is this insertion of the seal into a special groove. The removal process here is based on sequential pulling of the rubber. It is best to start from the top corner of the door, since it is easiest to grab the edge from there.
Sequence of actions:
- Grab the edge of the seal with your fingers or carefully pry it with a plastic spatula.
- Pull the rubber towards you and slightly down, trying to pull the profiled part out grooves.
- Move along the perimeter, gradually releasing the seal from the groove. Do not pull too hard at one point so as not to tear the rubber.
- When the main part is free, carefully remove the seal completely.
Here you can use a flat object with a blunt edge to slightly move the groove and make it easier for the seal to come out. Act smoothly, jerking can lead to deformation of the door corner.
☑️ The process of removing the seal
If the seal is difficult to remove, you can lightly warm it with a hairdryer at the joint. Warm air will make the rubber softer and more pliable. However, do not overdo it with the temperature, so as not to melt the plastic of the door.
Removing the seal on screws and strips
In models where the seal is pressed by a strip, the process requires more time and accuracy. The key point here is the safety of fasteners and the integrity of the holes in the door. Working with screws requires precision.
Action algorithm:
- 🔍 Inspect the inside surface of the door and find all the screws holding the clamping bar.
- 🔧 Select a screwdriver exactly to the size of the screw slot so as not to tear off the head.
- 🔄 Unscrew the screws sequentially, loosening them one at a time, rather than removing them completely at once. This will help avoid misalignment.
- 📏 Place all screws in a magnetic tray or jar to avoid losing them.
After the screws are removed, carefully remove the clamping bar. Below it you will see the edge of the seal. Release it and remove the entire structure. Sometimes the strip can dry to the body, in which case it can be slightly pryed with a plastic card.
When reinstalling, it is important not to overtighten the screws, as this can lead to deformation of the thin metal of the door or the strip itself. Tighten them evenly around the entire perimeter.
What to do if the screw is torn off?
If the head of the screw is torn off, try using a rubber layer between the screwdriver and the screw for better grip, or carefully drill out the rest of the fastener if it is not needed for reuse.
Cleaning and surface preparation
After removing the seal, access to hidden cavities opens, where dirt, grease and mold accumulate over the years. This step cannot be ignored, since installing new or cleaned rubber on a dirty surface will nullify all efforts.
Carefully wipe the free groove or door surface with a damp cloth using a mild detergent. To remove old grease, you can use a weak solution of soda or specialized kitchen products. The main thing is to avoid getting aggressive chemicals on plastic elements.
Pay special attention to the corners and joints where dirt most often gets clogged. Use cotton swabs for hard to reach areas. After wet cleaning, be sure to wipe the surface dry.
If rust is found on the surface of metal or plastic, it must be cleaned with fine sandpaper and treated with an anti-corrosion compound so that it does not transfer to the new seal.
Comparison of restoration and replacement methods
After removing the seal, the owner is faced with the question: repair the old one or buy a new one? The decision depends on the condition of the part. Below is a table that helps you decide on further actions.
| Criterion | Restoration (Cleaning/Boiling water) | Replacement of seal |
|---|---|---|
| Rubber condition | Integral, but deformed | Cracks, breaks, petrification |
| Cost | Minimum (water, means) | High (price of part + work) |
| Efficiency | Temporary (up to several months) | Full restoration of tightness |
| Complexity | Low | Average (requires accuracy) |
If you choose the restoration path, you can try pouring boiling water over the removed seal. Hot water helps straighten out creases and restore elasticity to the rubber. After this procedure, the part must be thoroughly dried before installation.
However, if the rubber has lost its magnetic properties or has visible mechanical damage, no traditional methods will help. In this case, the only right decision would be to buy an original or high-quality analogue.
⚠️ Attention: When buying a new seal, pay attention not only to the model of the refrigerator, but also to the year of manufacture. The design of the doors could change even within the same series.
Frequently asked questions (FAQ)
Is it possible to remove the seal without damaging it and then put it back?
Yes, if you act carefully and without jerks. Rubber has shape memory, but can become deformed if stretched too much. When removing, try not to stretch the corners and remove the profile from the groove evenly along the entire length.
What is the best way to wash the seal after removal?
Use warm water with the addition of mild soap or dishwashing detergent. Avoid chlorine-containing products and aggressive solvents, which can dry out the rubber and accelerate its aging.
How long does the seal take to dry after washing before installation?
It is recommended to let the seal dry completely so that there is no moisture left inside, which can cause mold. This usually takes several hours at room temperature. You can speed up the process by wiping it with a dry absorbent cloth.
Do you need to lubricate the seal before installation?
You do not need to lubricate the rubber itself, but you can lightly moisten the groove with water or soapy water to make insertion easier. Some experts advise wiping the rubber with glycerin to maintain elasticity, but this is not a mandatory requirement.
