The appearance of ice in the corners of the chamber, increased energy consumption and extraneous sounds during compressor operation often indicate a violation of the tightness of the refrigeration circuit. Owners of the popular two-chamber model Atlant MXM 162 regularly face the problem of wear of the sealing rubber, which over time loses elasticity and deforms. Loose door fit leads to a constant influx of warm air, forcing the unit to work in increased mode, which can ultimately cause breakdown of expensive components.
Timely replacement of the seal is not just an aesthetic procedure, but a necessary measure to extend the life of the equipment. Unlike more modern models, where the profile can be glued, the fastening system in a groove or using self-tapping screws is often used, which greatly simplifies self-repair. However, in order for the new rubber to fit perfectly and serve for a long time, it is important to know the nuances of dismantling the old part and preparing the surface. Atlant MXM 162 a fastening system in a groove or using self-tapping screws is often used, which greatly simplifies self-repair. However, in order for the new rubber to fit perfectly and last a long time, it is important to know the nuances of dismantling the old part and preparing the surface.
In this article we will analyze in detail the entire process, from choosing a compatible spare part to the final adjustment of the door. You will learn how to avoid common mistakes that beginners make when trying to quickly “seat” a new seal. It is critically important to consider that rubber seals for MHM 162 may have different hardness depending on the manufacturer, and require mandatory "keeping" before installation.
Diagnostics of the condition of the seal rubber
Before buying a new part, you need to make sure that the problem lies precisely in the wear of the seal, and not in a misaligned door or a malfunction of the thermostat. Visual inspection is the first stage of diagnosis. Carefully examine sealing profile the entire perimeter of the door: look for cracks, creases, areas where the rubber has become hard and brittle. Often, deformation is noticeable in the lower part of the door, where the main load falls.
There is a simple and effective way to check the tightness, known as the paper test. Take a regular A4 sheet, open the refrigerator door and place the sheet across the seal so that part of it hangs out. Close the door, holding the paper.
- 📄 If the sheet is pulled out with noticeable force and breaks, the seal is in order.
- 📄 If the paper slides freely or falls out on its own, in this place the seal is broken.
- 📄 Test at several points around the perimeter, especially in the corners and in the middle of the sides.
Another sign of wear is the formation of condensation or “dew” on the outside of the metal door rim. This occurs when warm, moist air from a room enters the interior, cools at the walls and deposits moisture, which can then freeze to form an ice crust. If you notice that the refrigerator began to turn on more often, and the food in the upper part of the chamber began to dry out or, conversely, become covered with frost, this is a sure signal to action.
⚠️ Attention: If, upon visual inspection, the rubber is intact, but does not fit, the problem may be in the door hinges. Try to lightly press the door with your hand in the problem area while the compressor is running. If the hum disappears or becomes quieter, then the problem is in the fit geometry, which can sometimes be corrected by adjustment without changing the tires.
Choosing a compatible seal for Atlant MXM 162
The spare parts market offers many options, but for the model MHM 162 it is important to choose a profile with the correct cross-section and magnetic properties. Original spare parts of the brand Atlant are considered the standard, since their geometry perfectly matches the factory door grooves. However, there are also high-quality analogues from third-party manufacturers, which may cost less, but require more careful adjustment.
When choosing, pay attention to the type of magnetic insert. Modern refrigerators use solid magnetic tape, while in older modifications of the MXM 162 profiles could be installed with magnets or even without them (where the clamping was carried out only due to the elasticity of the rubber). Magnetic seal provides more reliable and silent closing.
The comparison table will help you make the choice:
| Sealant type | Material | Service life | Installation features |
|---|---|---|---|
| Original Atlant | Special rubber | 7-10 years | Perfect fit in the groove |
| Analogue (China/Turkey) | Rubber engineering | 3-5 years | May require trimming corners |
| Universal profile | Silicone/Rubber | 2-4 years | Requires glue or complex fit |
When purchasing a part, be sure to check its integrity. The seal should not have creases, especially in corner areas, since it will be extremely difficult to straighten them later. It is also worth smelling the product: a sharp, chemical smell often indicates a low quality material that can dry out quickly.
Necessary tools and workplace preparation
To replace the seal with high quality, you do not need complex professional equipment, but a set of tools should be at hand. The main task is to dismantle the old rubber without damaging the plastic or metal door profile, and carefully install the new one. It is better to carry out work in good lighting, as the grooves can be dark and narrow.
You will need the following tools:
- 🔧 Flat-head screwdriver (blade width 3-4 mm) - for prying off the edges of the seal.
- 🔧 Phillips screwdriver (PH2) - if in your modification the profile is screwed with self-tapping screws.
- 🔧 Construction or household hair dryer - for heating and straightening the new rubber.
- 🔧 Rags and degreaser (alcohol, white spirit) - for cleaning the groove from dust and grease.
Preparing a new elastic band is a key step that many people ignore. After delivery from the warehouse, especially in the cold season, the seal is in a compressed state (folded into a ring or packed in a bag). He needs to rest at room temperature for at least 24 hours. This will allow the material to take a natural shape and straighten the corners.
If you plan to use glue for fixation (which is recommended for models where the profile does not sit tightly), purchase a special glue for rubber in advance, for example 88-N or its analogues. Do not use superglues (cyanoacrylates), as they make the rubber hard and brittle, which will lead to rapid tearing.
⚠️ Attention: Be careful when working with a hair dryer. Do not direct a hot stream of air at the plastic elements of the door or the inner lining of the refrigerator for more than 2-3 seconds, so as not to melt them. Warm up only the rubber itself.
Removing the old seal
The process of removing the old rubber requires care. In the model Atlant MHM 162 the seal can be attached in two ways: inserted into a special groove on the door or fixed with screws through a plastic strip. First, carefully inspect the inner perimeter of the door.
If you see the heads of the screws, they need to be unscrewed. If there are no fasteners, then a groove connection is used. Take a flathead screwdriver and carefully pry up the corner of the seal. Try not to scratch the metal of the door. Move the tool along the groove, gradually releasing the rubber profile.
It often happens that old rubber “sticks” to the surface or becomes clogged with dirt, causing it to tear when removed. In this case, you can lightly warm the problem area with a hairdryer. The main thing is to remove all the old material completely, leaving pieces in the groove.
After dismantling, be sure to inspect the groove itself. Fragments of old rubber, dust or oxides could remain inside. Wipe the channel with a rag soaked in degreaser. A clean surface is the key to ensuring that the new seal will lie flat and adhere tightly.
☑️ Preparation for installation
Technology for installing a new seal
Installation begins from the upper corner of the door. Insert the edge of the seal into the groove, making sure that the profile flange fits correctly into the groove. Move along the perimeter, gradually pressing the rubber with your fingers. On straight sections this is easy to do, but corners require special attention.
In the corners of the MXM 162 the rubber may bulge. To lay it correctly, use the "tension" method. Pull the seal slightly to the side opposite the corner, straighten the fold and then tuck it tightly into the groove. If the rubber is hard, help yourself with a flat-head screwdriver, but act without fanaticism so as not to break through the material.
The secret of ideal corners
If the corner still does not want to lie flat, try making a small cut on the inside of the seal flange (not through!) at the bend. This will relieve the tension in the material and it will straighten out. After installation, the cut will be invisible.
If the design of your door involves fastening with screws, then after laying the profile in the groove, you need to screw the decorative strip. Tighten the screws evenly, moving from the center to the edges to avoid distortions.
In cases where the new seal sits too loosely (typical of some analogues), it is recommended to use glue. Apply a thin layer of glue into the door groove and onto the counter part of the profile, let it dry for 5-10 minutes (according to the instructions on the tube), and then press firmly. For fixation, you can use masking tape while it dries.
After installation, walk around the entire perimeter again with your hand, checking the tightness of the fit. Make sure that there are no gaps anywhere between the rubber and the door body.
Final processing and checking the result
Immediately after installation, the new seal may not look ideal: small waves or leaks are possible. This is fine. Use a hair dryer for final shaping. Warm the problem areas to a temperature of 50-60 degrees (the rubber should become warm to the touch, but not hot) and immediately press them with your finger, giving the desired shape.
After heat treatment, close the refrigerator door and leave it alone for 3-4 hours. This is necessary so that the rubber “remembers” its position and cools down in a compressed state. Only after this can a final tightness check be carried out using the method with a sheet of paper described at the beginning of the article.
Check the operation of the magnets. The door should close with a characteristic soft pop and hold securely. If you open the door and then release it at a distance of 5-10 cm from the body, it should be attracted by magnets. If this does not happen, it means there is a gap somewhere.
Common mistakes when replacing and how to avoid them
The most common mistake is trying to install “cold” rubber immediately after unpacking. The unheated, compressed material in the package has a “shape memory” of the ring. If it is forcibly straightened and secured, after a day it will begin to shrink back, forming cracks in the corners.
The second mistake is the use of inappropriate lubricants. Some craftsmen advise lubricating the rubber with oil or Vaseline to make it softer. You can't do this! Mineral oils destroy the structure of rubber, it swells and loses elasticity. For care, use only special silicone-based products.
The third mistake is ignoring the adjustment of the hinges. If you install new rubber and the door is warped, the seal will still not work. After replacing, always check the horizontalness of the door and, if necessary, tighten the adjusting bolts on the hinges.
- ❌ Using aggressive chemicals to clean the groove.
- ❌ Strong stretching of the rubber during installation (it will shrink and holes will appear).
- ❌ Refusal to wait before by connecting the refrigerator to the network (if work was done with glue or heating).
Compliance with technology will allow you to forget about the problem of loss of cold for many years. A correctly selected and installed seal is a guarantee of stable temperature and energy savings.
Questions and answers (FAQ)
How often do you need to change the seal on Atlant MHM 162?
The average service life of a high-quality seal is 5-7 years. However, if the refrigerator is in a hot kitchen or next to a stove, the rubber may dry out faster. It is recommended to carry out an inspection every 1-2 years.
Is it possible to restore the old seal without changing it?
You can temporarily improve the fit by heating the rubber with a hairdryer and closing the door tightly for several hours. Silicone lubrication also helps. But if the rubber is cracked or has lost its magnetic properties, replacement is inevitable.
Where can I find the seal markings for ordering?
The marking is usually applied to the inside of the seal itself (visible when folded) or on a sticker inside the refrigerator compartment. For MHM 162, universal profiles with a length of 130-135 cm are often suitable for one door, but it is better to look for spare parts by catalog number.
Why did the door begin to close tighter after replacement?
The new seal always has greater resistance. This is fine. After 1-2 weeks of active use, the rubber will wear out and the door will move easier. If the door does not close at all, the seal may be too thick or incorrectly installed in the groove.
