The tightness of the refrigeration chamber is the foundation for stable operation of the compressor and maintaining food freshness. If you notice that frost has appeared on the walls of the chamber, and the motor is humming almost without interruption, then it’s time to check the condition of the rubber edging of the door. Replacing the seal on a refrigerator Position is a procedure that you can actually do yourself, without contacting a service center, if you act carefully and consistently. In this article we will analyze all the nuances of the process, from choosing the appropriate part to the final adjustment of the hinge.
The rubber contour performs a critical function: it insulates the internal volume from the warm air of the room. Over time, the material loses its elasticity, cracks or deforms, no longer fitting tightly to the metal body. Leaks leads to constant leakage of cold, which causes the equipment to wear out. Ignoring this problem inevitably leads to costly repairs of the compressor or complete replacement of the unit.
Before taking active steps, you need to make sure that the problem lies precisely in the rubber, and not in the skew of the door or contamination of the surface. Sometimes it is enough to simply wash the groove and the rubber itself to restore the fit. However, if the material has become hard, visible tears or jams have appeared that cannot be straightened out, then installation of a new seal is the only correct solution to restore the energy efficiency of your Pozis.
Diagnostics of the condition and selection of components
The first step should always be thorough diagnosis. Visual inspection may not be enough, since microcracks are often hidden in folds. Run your hand along the entire length of the contour: you should feel uniform elasticity. If the rubber crumbles under your fingers or has a sticky coating, these are signs of aging polymers. It is also worth checking the magnetic tape that is built inside the profile - it should provide tight adhesion around the entire perimeter.
Refrigerators Pozis, such as the popular models of the Rowan or Mirseries, are characterized by certain types of profiles. It is important to understand that there are no universal solutions. Trying to install a “similar” seal may result in the door not closing or, on the contrary, moving away too much. The original spare part has the exact geometry of the corners and the correct thickness of the magnetic insert.
When choosing a new part, pay attention to the following parameters:
- 📏 Profile type —must completely match with the factory one (usually a petal or baguette type with an internal cavity).
- 🧲 Magnetic system —check the adhesion force, since weak magnets will not ensure tightness.
- 🏭 Material —preferably rubber products with antibacterial impregnation, and not cheap PVC, which will quickly harden.
⚠️ Attention: If you buy a seal on the market or in a hardware store, be sure to take with you a sample of old rubber or exact measurements of the door. A difference of several millimeters can make installation impossible without additional adjustment.
Necessary tools and workplace preparation
High-quality installation is impossible without proper preparation. You don't need fancy power tools, but you should have a set of hand tools on hand. The main task is to remove the old rubber without damaging the plastic door body and the paintwork of the metal. It is better to carry out work in good lighting in order to see all the fasteners and the condition of the seat.
For dismantling and installation you will need:
- 🔧 Screwdrivers (Phillips and flat) - for removing decorative panels and fasteners.
- ✂️ Scissors or construction knife - for trimming excess material.
- 🧼 Soap solution and sponge - for degreasing the surface before installation.
- 🔥 Hair dryer (construction or household) - necessary for softening the rubber before installation.
Pay special attention to cleanliness. Dirt, remnants of old glue and food crumbs often accumulate in the groove where the seal is inserted. If this area is not cleaned, the new seal will lie unevenly and the seal will be compromised immediately. Use a damp cloth and, if necessary, a mild detergent, then thoroughly wipe the surface dry.
Removing the old seal
The process of removing old rubber depends on the type of fastening used by the manufacturer. In most modern models Position the seal is inserted into a special groove around the perimeter of the door. In older models, it may be glued or screwed with screws hidden under the inner panel. Determine the type of fastening by pulling the corner of the seal: if it simply comes out of the groove, you are lucky.
If the seal is glued, you need to act extremely carefully. Heat the rubber with a hairdryer to soften the adhesive layer and pull slowly, using a spatula or a flat-head screwdriver wrapped in fabric. Sudden movements can lead to deformation of the metal door, which will be very difficult to correct. Remove residual adhesive mechanically or using special solvents that will not damage the paint.
In the case where the seal is held on self-tapping screws, the action algorithm is as follows:
- Carefully bend the inner edge of the rubber to gain access to the screw heads.
- Unscrew all fasteners according to perimeter.
- Remove the rubber profile and check the condition of the metal underneath for corrosion.
☑️ Preparation for dismantling
Methods for installing a new seal
There are two main installation methods: in a groove and with glue. For refrigerators Posis the first option is most common, since it is provided for by the design. It is recommended to warm up the new seal before installing it. Rubber becomes hard in the cold, and straightening it out in the corners will be problematic. Place the new set in a warm room for several hours or gently warm it with a hairdryer.
The installation technology in the groove is as follows. Start at the top corner of the door. Insert the seal so that the profile flange fits tightly onto the metal and the edge fits into the groove. Move gradually, fixing the rubber with your fingers or a blunt object (for example, the handle of a screwdriver). Do not stretch the rubber too much, otherwise it may tear or later shrink, forming a gap. In the corners, the profile must be carefully cut at an angle of 45 degrees or a neat fold must be formed if the design allows it.
If you use the glue method (for models without a groove or if the channel is damaged), follow the instructions on the glue package. Apply the compound in a thin layer to both metal and rubber, let it dry (“set”), and then press firmly. Remove excess glue immediately before it hardens.
| Work stage | Actions | Control result |
|---|---|---|
| Preparation | Cleaning the groove, warming up rubber | The surface is dry and clean |
| Start of installation | Fixing the upper corner | The rubber fits tightly, without gaps |
| Main installation | Tucking into the groove along the perimeter | No stretch marks and waves |
| Finish | Checking corners and magnets | The door closes with a characteristic bang |
Adjusting the door and eliminating leaks
After installing a new seal, a situation often arises when the door does not close completely or, conversely, too tightly. This is normal, since the new tires have not yet “sat” into place. However, if the gap is obvious, the hitch may need to be adjusted. On refrigerators Position hinges usually allow you to adjust the position of the door in the vertical and horizontal planes.
To check the tightness, use a simple test with a sheet of paper. Clamp the sheet with the door around the perimeter. If it is removed with force, the seal is good. If the sheet falls out or dangles loosely, the seal does not fit tightly in this place. In such places, you can locally heat the rubber with a hairdryer and press it so that it takes the desired shape.
It is also worth checking the horizontal installation of the refrigerator itself. If the unit is tilted backwards, the door will open on its own and the seal will not work correctly. Adjust the front legs so that the body has a slight tilt back (about 2 degrees), which will allow the door to flow by gravity when closing.
⚠️ Attention: Do not use aggressive chemicals or abrasives to clean the new seal in the first weeks of operation. Allow the material to finally set and lose the smell.
What to do if the door is skewed?
If after replacing the seal you see that the door is skewed (one corner is higher than the other), perhaps the problem is not in the rubber, but in the hinges. Try loosening the top or bottom hinge mounting bolts, leveling the door and retightening the bolts. Sometimes it is necessary to replace the hinges themselves if they are deformed.
Common mistakes and ways to eliminate them
Beginners often make mistakes that nullify all efforts. The most common is excessive stretching of the seal during installation. Stretched rubber compresses over time, and cracks appear in the corners. Always lay the sealant with a small margin, and trim off the excess after fixing.
Another mistake is ignoring the corners. It is in the corners that gaps most often form. Make sure that the profile in the corner is formed correctly, without creases or voids. If the corner does not hold its shape, you can drop a little special glue for rubber there, but this must be done very carefully.
Comparison of correct and incorrect actions:
- ❌ Error: Installing cold rubber immediately from the store.
✅ Solution: Let it lie in a warm place for 24 hours or warm it with a hairdryer. - ❌ Error: Using superglue instead of a special adhesive.
✅ Solution: Superglue makes the rubber “glassy” and brittle, you need elastic glue. - ❌ Error: An attempt to straighten the creases by force.
✅ Solution: Only heating will help straighten the profile without damage.
How often do you need to change the seal on a Pozis refrigerator?
Service life The sealant lifespan is on average 5-7 years under normal operating conditions. However, if the refrigerator is in a high-temperature kitchen or next to a stove, the rubber may deteriorate faster - after 3-4 years. Check the condition of the rubber regularly: if it has become hard or sticky, replacement is necessary.
Can a universal seal be used instead of the original?
You can use a universal seal, but with caution. It requires adjustment to size and often holds its shape less well in corners. For refrigerators Pozis it is better to look for original spare parts or high-quality analogues designed specifically for this brand, since their door geometry is specific.
Why did the refrigerator become louder after replacing the seal?
This may be due to the fact that the new the seal fits too tightly, and the compressor takes longer to complete the first cooling cycle, or the door began to close more tightly, and you simply began to hear the operation of the unit better. If the noise is not accompanied by vibration or knocking, this is normal. After a couple of weeks, the work will stabilize.
