The appearance of condensation on the internal walls, freezing of an ice crust or a noticeable flow of warm air when touching the door are the first alarm signals indicating wear. sealing rubber. Owners of brand household appliances Polyus often face the need to replace this element, since rubber materials lose elasticity over time and cease to ensure the tightness of the chamber.
Timely replacement of the cuff allows not only restore normal temperature conditions, but also significantly reduce energy consumption, saving the compressor from operating under high load. If you notice that the refrigerator Polyus began to turn on more often or moisture has appeared inside, you cannot ignore the problem, otherwise the compressor itself may require repairs.
In this article we will analyze in detail the process of selecting compatible parts, preparing the workplace, and the very procedure for installing a new seal. You will learn what tools you will need, how to properly prepare the profile for installation and what to do if the new rubber does not fit the first time.
Diagnostics of the condition of the seal and selection of spare parts
The first step before starting work is a thorough visual and tactile check of the current condition of the seal. The elastic band should be soft, elastic and fit snugly to the body along the entire perimeter of the door. If you run your hand and feel cracks, abrasions or creases, then the part requires replacement.
There is a simple and effective way to check for leaks, known as test with a sheet of paper. You need to press a regular sheet of office paper between the door and the body of the refrigerator in different places around the perimeter. If, when the door is closed, the sheet can be easily pulled out without effort or it falls out on its own, then the seal is broken.
⚠️ Attention: If the rubber band is simply dirty, try first washing it thoroughly with warm water and a mild detergent. Sometimes the loss of tightness is caused by a sticky coating of fat, which prevents a tight fit, and not by physical destruction of the material.
When choosing a new part for a refrigerator Pole it is important to consider that the brand produced the equipment in different years, and the door designs could differ. There are no universal rubber bands, so it is best to look for a spare part by the catalog number indicated in the technical documentation, or take measurements of an old model.
Pay attention to the section profile: it can be single-lobed, double-lobed or magnetic with a different number of cavities. It is critically important to select an exact copy of the profile, since even a millimeter mismatch in geometry can lead to a loose fit and loss of cold.
- 🔍 Visual inspection: look for microcracks, discoloration (whitening of rubber) and mechanical damage.
- 🧲 Checking the magnets: make sure that the magnetic tape inside the elastic band is not demagnetized and is evenly distributed.
- 📏 Measurements: measure the height, width and diagonal of the door to compare with the parameters of the new spare part.
Necessary tools and worker preparation places
To successfully replace the seal on the refrigerator Pole no complex professional equipment is required, however, having a certain set of tools will greatly simplify the task and speed up the process. It is best to carry out preparation in good lighting so that you can see all the fasteners and grooves.
You will need a flat-head screwdriver for prying up decorative strips or screws, as well as a Phillips screwdriver for dismantling door handles or hinges, if the design requires it. A construction hair dryer will not be superfluous, which will help soften the new rubber for a tighter fit in the corners.
☑️ Tools for replacing the rubber
Free up space in front of the refrigerator in advance to have access to the doors from all sides. Cover the floor with a soft cloth or cardboard so as not to scratch the door covering or the floor if tools or parts accidentally fall.
Be sure to disconnect the refrigerator from the power supply before starting any work. Although there is no electrical circuit involved in replacing rubber bands, safety should be a priority when working with appliances. Let the chamber warm up a little if there was ice in it so that condensation does not interfere with operation.
Removing the old sealing rubber
The process of removing the old seal depends on the method of its fastening, which may vary in different models of refrigerators Pole. Most modern modifications use the method of inserting an elastic band into a special groove on the inner plastic panel of the door; fastening with screws or glue is less common.
If the elastic is screwed on with screws, you need to carefully bend the inner edge of the seal to gain access to the fastener heads. Using a Phillips screwdriver, unscrew all the screws around the perimeter, moving from the corners to the center so as not to deform the plastic.
In the case where the seal is simply inserted into the groove (the most common option for Polyus), start pulling it out of the groove, starting from one of the upper corners. Proceed carefully, trying not to damage the plastic door body with the sharp edges of the old rubber.
⚠️ Attention: Do not use metal objects (knives, chisels) to pick the grooves unless absolutely necessary. The plastic on older refrigerators can be brittle and easy to break, requiring replacement of the entire door panel.
After removing the rubber band, thoroughly clean the groove to remove any old adhesive, dirt, grease, or oxides. To do this, use warm soapy water and a soft brush. The surface must be perfectly clean and dry before installing the new part.
- 🧹 Cleaning the groove: remove all dirt so that the new rubber fits tightly and without gaps.
- 🔍 Checking the housing: inspect the plastic for cracks or chips that could have formed under the old rubber.
- 🧼 Degreasing: wipe the installation area with alcohol or degreaser for better adhesion, if gluing is required.
Technology for installing a new seal
Installing a new seal - the most critical stage, requiring patience and accuracy. Before installation, it is recommended to place the new rubber band in a warm room for several hours so that it warms up and becomes more flexible, especially if delivery was carried out during the cold season.
Start installation from the top corner of the door. Insert the edge of the seal into the groove or align the screw holes. If a screw fastening is used, tighten all the screws first, without tightening them all the way, so that you can adjust the tension.
When inserting into a groove (dovetail profile or similar), press the seal evenly around the entire perimeter. Work from the top corner down, then along the bottom and up the other side, finishing at the top corner. Do not stretch the rubber too much so that it does not deform.
In the corners of the refrigerator door Pole often folds form. To straighten them, use a hair dryer: heat the problem area and straighten the rubber with your fingers, pressing it against the body until it cools. This will ensure a perfect fit in complex geometric areas.
| Mounting type | Complexity | Required tools | Installation time |
|---|---|---|---|
| Insert into groove | Medium | Screwdriver, hair dryer | 20-30 min |
| On screws | Low | Phillips screwdriver | 15-20 min |
| Adhesive joint | High | Glue, degreaser | 40-60 min |
| On clips | High | Special. tool | 30-40 min |
Features of installation on two-chamber models
Refrigerators Polyus with two chambers (freezing and refrigerating) have their own design features. Often, the upper and lower doors may have different seal designs, and it is impossible to confuse them during installation, since the profiles may differ in rigidity and shape.
When replacing the rubber band in the freezer, where temperatures are lower, it is important to ensure a particularly tight fit, since the temperature difference is maximum here. Make sure that the magnetic tape in the freezer seal has sufficient adhesive force.
If your refrigerator Polyus equipped with a No Frost system, pay attention to the integrity of the seal around the air circulation channels (if they pass through the door). Incorrect installation can disrupt airflow and lead to the formation of ice inside the air ducts.
After installation on two-chamber models, be sure to check the operation of the door closers (if any) and make sure that the doors close tightly even with a slight misalignment that may occur during the installation process.
Adjusting doors and checking the result
The final stage is adjusting the position of the doors. After installing a new, larger rubber band, the door may no longer close tightly or begin to touch the body. In this case, it is necessary to adjust the hinges.
Use a wrench or screwdriver (depending on the hinge model Pole) to loosen the mounting bolts. Move the door slightly in the desired direction and tighten the fasteners again. Check the horizontal installation of the refrigerator using a building level - skewed housing is often the cause of loose closure.
⚠️ Attention: Do not tighten the hinge bolts all the way right away. First, tighten them, check the operation of the door, and only then make the final tightening. Excessive force can strip the threads in the metal body of the refrigerator.
Repeat the test with a sheet of paper around the entire perimeter. Now the sheet should be pulled out with noticeable effort, but not torn. Also visually inspect the fit line: it should be uniform, without tears or bulges.
Plug in the refrigerator and leave it running without load for 2-3 hours. After this, check the temperature inside the chambers. If the cold is distributed evenly and there is no excess condensation on the walls, then the replacement was successful.
Frequent errors and ways to eliminate them
Even if they follow the instructions, beginners can make mistakes that will negate all their efforts. One of the most common is insufficient heating of the corners of the new rubber band. Cold rubber “remembers” its packaging shape and can bulge, forming gaps.
Another mistake is the wrong choice of cleaning agent. Using aggressive chemicals (acetone, gasoline) for degreasing can corrode the plastic of the door or the new rubber itself, making it brittle. Use only specialized products or a mild soap solution.
What to do if the rubber still does not fit?
If after installation and adjustment there are still gaps, try warming the problem areas again with a hairdryer and pressing the door with something heavy (through a towel) overnight. Sometimes it takes time for the rubber to “settle.”
They also often forget to lubricate the rubber after installation. Dry rubber wears out faster and can squeak. Wipe it with a weak solution of silicone grease or a special product for caring for rubber seals.
- 🚫 Ignoring the level: installing a new seal on a skewed refrigerator will not work.
- 🚫 Stretch: strong stretching of the rubber during installation will lead to its rapid rupture or loss of magnetic properties.
- 🚫 Dirt in the groove: remaining dust or old glue will not allow the new part to fall into place.
FAQ: Frequently asked questions
Where find the catalog number of the rubber band for my Polyus refrigerator?
The catalog number is usually indicated in the operating instructions. If the documentation is lost, the number can be found on a sticker inside the refrigerator compartment (often on the side wall or ceiling) or on the manufacturer's website for your unit model. You can also measure the old seal and select an analogue in size in specialized stores.
Is it possible to restore an old rubber band instead of replacing it?
You can temporarily restore elasticity by soaking the rubber band in hot water or treating it with a silicone spray. However, if there are cracks or loss of magnetic properties, these measures will only have a short-term effect. For reliable operation of the refrigerator Polyus it is better to make a complete replacement.
How long does a new seal last?
The service life of a high-quality seal is on average 5-7 years with proper care. Regular washing and lubrication with silicone help extend this period. Aggressive chemicals and mechanical damage can shorten the operating time.
Why did the door begin to close tighter after replacement?
This is a normal situation. A new elastic band is always larger and denser than the old one, which has shrunk over time. In addition, increased air resistance in the chamber (vacuum effect) may require greater force to open. After 1-2 weeks of development, the door will become easier to move.
