Deterioration of the tightness of the refrigeration chamber - one of the most common problems that equipment owners face Pozis after several years of active use. If you notice that the door no longer fits tightly to the body, and ice forms inside even with a working thermostat, then it’s time to pay attention to sealing rubber band. This element is responsible for creating a vacuum effect that keeps the cold inside and does not let warm air outside.
Timely replacement of the cuff allows not only to restore the temperature regime, but also to significantly reduce energy consumption, since the compressor does not have to work non-stop to compensate for cold leaks. Many users mistakenly believe that it is necessary to call a specialist to carry out this procedure, but the design of refrigerators Pozis allows you to perform the replacement yourself, with a minimum set of tools at hand.
In this article we will analyze in detail all stages of the process, from choosing the appropriate seal model to the final adjustment of the door. You will learn how to properly prepare the surface, avoid common mistakes during installation and check the quality of the work performed. Properly carried out repairs will extend the life of your unit and return it to its original efficiency.
Diagnostics of the condition of the seal and signs of wear
Before you start purchasing a new part, you need to make sure that the problem lies precisely in the rubber, and not in a skewed door or faulty hinges. The first visual sign of wear is the appearance of visible cracks, scuffs, or areas where the rubber has become hard and brittle. Over time, the material loses its elasticity under the influence of temperature changes and detergents, no longer tightly fitting the contour of the case.
There is a simple and effective way to check the tightness, which does not require special equipment. You will need a regular A4 sheet of paper or a banknote. Open the refrigerator door slightly, place a sheet of paper between the body and the seal, and then close the door tightly. Now try to pull out the sheet:
- 📄 If the paper is removed with noticeable effort and tears, it means that in this area tightness tightness has been preserved.
- 📄 If the sheet falls out freely or is pulled out without resistance, a formation has formed in this area gap.
- 📄 The check must be carried out along the entire perimeter of the door, paying special attention to the corners and areas near the hinges.
⚠️ Attention: If gaps are found only in the upper or lower part of the door, the problem may not be in the rubber, but in the sagging of the door. In this case, first try to adjust the position of the door by tightening the hinge mounting bolts, and only after that evaluate the condition of the seal.Another indirect sign of wear is the formation of a “fur coat” or condensation in certain areas of the freezer or refrigerator compartment. Warm moist air penetrating through leaks instantly freezes on the cold walls. If you see that ice is growing locally, for example, only on one side of the door, this is a sure signal that Choosing the appropriate seal model for Pozis the sealing contour is damaged or deformed in this place.
Selecting the appropriate seal model for Pozis
Refrigerators Pozis have been produced for several decades, and during this time the model range has undergone changes, which also affected the design of the doors. Seals can differ not only in size, but also in the method of fastening, cross-sectional profile and material of manufacture. Most often in the equipment of this brand there are magnetic tapes, which can be removable or non-removable, although the latter are practically not used in modern models.
When choosing a new rubber band, it is critical to know the exact model of your refrigerator. It is usually indicated on a sticker located inside the camera or on the back wall of the case. Buying a universal seal “by eye” often results in the part not fitting into the groove or forming folds, which again breaks the seal. Pay attention to the following parameters:
- 🔍 Profile type: one-, two- or three-lobe seals have different sealing efficiency.
- 🔍 Method of fastening: in most models Pozis rubber is inserted into a special groove (profile) on the plastic base of the door.
- 🔍 Material: it is preferable to choose rubber based on natural rubber with antibacterial impregnation, which retains elasticity longer.
If the original spare part cannot be found, you can use universal analogs that are cut to size. However, in this case, you will have to form the corners yourself, heating the material with a hairdryer and fixing it in the desired position until it cools. For beginners, it is better to look for a model seal, since it already has the factory shape of the corners and exactly matches the geometry of your door. Pozis.
Where to look for the model marking?
The marking plate on Pozis refrigerators is most often located inside the refrigerator compartment on the left side wall or on the rear panel outside. Look for a code that starts with letters (eg RD, RK, F) followed by numbers. It is this code that must be reported to the spare parts seller.
Necessary tools and preparation of the workplace
Replacing the sealing rubber is a procedure that does not require complex professional equipment, but accuracy and the availability of the right tools play a decisive role here. To make the process go smoothly and take a minimum of time, prepare everything you need in advance. It is better to work in good lighting, ensuring free access to the refrigerator from all sides.
You will need the following set of tools and materials:
- 🛠️ Hair dryer: household or construction (at minimum power) for heating the rubber before installation.
- 🛠️ Screwdrivers: cross and flat for removal decorative panels or dismantling the door, if necessary.
- 🛠️ Soap solution: to facilitate the sliding of rubber in the channel groove.
- 🛠️ Clean rags: for degreasing and cleaning the surface before installation.
⚠️ Attention: Do not use sharp metal objects (knives, screwdrivers) to pick at the grooves of the seal unless absolutely necessary. The door plastic Pozis can be fragile, especially on older models, and it is easy to damage it or break the mounting lugs.Before starting work, it is advisable to defrost the refrigerator and unplug it, although replacing the rubber itself does not require access to electrical components. This will also allow you to thoroughly wash and dry the door, removing any dirt or grease that may have accumulated in the folds of the old cuff. A clean surface is the key to ensuring that the new rubber will lie flat and hold securely.
Removing the old sealing rubber
The process of removing the old seal depends on the design of the door of your model Pozis. In most cases, the rubber is not glued, but inserted into a special groove on the plastic base of the door. If you see that the edge of the rubber is simply tucked into the groove, the task becomes easier. Start from one of the upper corners, carefully bend the edge of the seal and pull it towards you.
Move gradually around the perimeter, removing the rubber from the channel. If there are areas where the rubber is glued (which is typical for very old models), use a hair dryer. Apply warm air to the affected area to soften the adhesive, and then slowly remove the tape. The main thing here is not to damage the plastic base of the door, since it will be difficult to restore its integrity.
After completely removing the old tape, it is necessary to thoroughly clean the channel. It often accumulates mold, old adhesive residue and dirt, which can prevent the new seal from fitting tightly. Wipe the groove with a damp cloth and soapy water, and then wipe dry. Make sure that there are no lint or debris left in the channel.
☑️ Preparation for installation
Completed: 0 / 5Installing a new seal: step-by-step instructions
Installing a new sealing gum is the most critical step that requires patience. Never try to tighten cold, hard rubber as it may tear or become deformed. If the rubber was stored in a cold room, let it sit at room temperature for several hours so that it straightens and becomes elastic.
Start installation from the top corner of the door, usually the hinge side or the opposite top corner, depending on the design. Insert the edge of the seal into the groove, making sure it is seated deeply and securely. Next, move around the perimeter, gradually filling the rubber into the channel. If the profile is tight, you can lightly moisten the edge with soapy water for better sliding, but do not overdo it so as not to disrupt the adhesion of the magnet.
Pay special attention to the corners. This is where gaps most often form. Warm up the corner areas with a hairdryer and press them tightly with your fingers, forming the correct bend. The rubber should completely fill the corner without leaving any voids. After the entire perimeter has been completed, check the fit again along the entire length.
Work stage Action Important nuance Start of installation Fixing the top corner Make sure that the magnetic tape does not jump out of the profile Laying on the side Tucking into the groove Move in small sections, checking the density Corner connections Heating and shaping Use a hair dryer to add elasticity Finish Checking the fit Make sure there are no waves or gaps ⚠️ Attention: If after installation you see that the rubber is wavy or puffy, do not ignore it. This means that it is either too long for this door, or is not laid correctly in the channel. Excess length can lead to rapid wear and loss of tightness.Adjusting the door and checking the result
After installing a new rubber band, the door may close too tightly or, conversely, not fit completely due to the changed thickness of the seal. In this case, the door position may need to be adjusted. On refrigerators Pozis usually it is possible to adjust the height and tilt of the door by tightening the support legs or adjusting the hinges.
If the door is skewed, loosen the fastening bolts on the hinges, level the door and tighten the fastenings again. Check the operation of the door: it should open smoothly, and when closed from a distance of 5-10 cm, it should itself be attracted to the body thanks to magnets. If the door opens by itself or slams, then the misalignment is still present.
Carry out the final tightness check a few hours after installation, when the rubber has finally taken its shape. Use the paper sheet method described at the beginning of the article. It is also worth listening to the operation of the compressor: if the refrigerator begins to work more quietly and turns on less often, it means thermal insulation restored successfully.

How often should you change the seal on the refrigerator Pozis?
The service life of the seal depends on the operating conditions and the quality of the material. On average, high-quality tires last 5-7 years. However, if you open the door frequently or use harsh cleaning chemicals, replacement may be necessary sooner. Check the condition of the cuff regularly.
Is it possible to restore an old rubber band instead of replacing it?
There is a method of “resuscitation” using boiling water, when the rubber is removed and soaked in hot water. This can temporarily restore elasticity if the rubber has simply become caked. However, if there are cracks or breaks, restoration is impossible - only a complete replacement.
How to lubricate the seal so that it does not dry out?
To care for the rubber, use a special silicone grease. It maintains the elasticity of the material and prevents drying out and cracking. Do not use vegetable oil or petroleum jelly, as they can destroy the rubber structure over time.
Why did the door become harder to close after replacement?
New rubber is always denser and more voluminous than the old one, so the pressing force increases. This is fine. After 1-2 weeks of active use, the rubber will soften a little and the door will close easier. If the door does not close at all, check whether it is installed correctly in the groove.
