The appearance of condensation on the inner walls of the chamber, freezing of the “coat” or the characteristic hum of a working compressor are the first signals that the tightness of the refrigeration circuit is broken. Owners of equipment Ariston often encounter the fact that sealing rubber loses elasticity over time, cracks or comes away from the body. Sealing tape is not just a rubber strip, but an important element of thermal insulation that keeps the cold inside and does not allow heat outside.
If you notice that the door does not close tightly, and visible gaps have formed between the body and the seal, you need to act urgently. Ignoring the problem will lead to increased energy consumption and accelerated wear of the compressor, which will work for wear, trying to compensate for heat loss. In this article we will look at how to carry out the replacement yourself, without resorting to the help of craftsmen.
The replacement process requires attentiveness and accuracy, but is quite within the capabilities of a home handyman. The main thing is to choose the right part and follow the installation technology to avoid distortions and re-appearance of cracks. Modern seals for Ariston refrigerators often have a complex geometric profile with a magnetic insert inside, which requires a special approach during installation. Let's look at all stages of the work in detail.
Diagnostics of the condition seal and troubleshooting
Before buying a new part, it is necessary to conduct a thorough diagnosis of the current condition of the door. Often the problem lies not in complete wear of the rubber, but in its contamination or deformation. A visual inspection allows you to identify cracks, abrasions and places where the rubber has become “stiff” and no longer adheres to the metal surface of the case. Pay special attention to the corners of the door and the area around the handle, since there the load on the material is maximum.
One of the most effective ways to check tightness is a test with a sheet of paper. Take a regular A4 sheet, open the door slightly and insert the paper across the seal so that part of the sheet hangs out. Close the door and try to pull out the sheet. If it is removed with noticeable effort or breaks, then the fit is good. If the paper slides freely or falls out on its own, a gap has formed in this place.
⚠️ Attention: Checking with a sheet of paper should be carried out along the entire perimeter of the door, moving in increments of 5-10 centimeters. A local leak at one point can cause icing of the entire chamber.
It is also worth paying attention to the appearance of the seal itself. If black dots of mold appear on the surface that cannot be removed by regular washing, or the rubber has become sticky and loose, its replacement is inevitable. Magnetic tapehidden inside the profile may weaken over time, but most often the problem is the physical wear and tear of the rubber base.
Choosing the right one seal for Ariston models
The spare parts market offers many options, but for refrigerators Ariston it is important to choose a part that fully matches the geometry of the original. Seals come in different profiles: single-chamber, double-chamber, with a “petal” or flat. An incorrectly selected profile will not provide the desired fit, even if the dimensions around the perimeter are the same. When choosing, be guided by the exact model of your unit, indicated on the nameplate inside the chamber.
The material of manufacture also matters. High-quality seals are made of special frost-resistant rubber or thermoplastic elastomer, which do not lose their properties at low temperatures. Cheap analogues may emit an unpleasant chemical odor or quickly crack. It is recommended to pay attention to the products of certified manufacturers specializing in components for large household appliances.
The table below shows the main parameters that you need to pay attention to when choosing:
| Parameter | Description | Importance |
|---|---|---|
| Type of fastening | In a groove (angular) or with screws | High |
| Section profile | Shape of the rubber cross-section | Critical |
| Material | Rubber, silicone, TPE | Average |
| Presence of magnet | Built-in magnetic tape | High |
Is it possible to use a universal seal?
Universal self-adhesive tapes are a temporary solution. They do not provide proper thermal insulation and quickly peel off. For a complete repair, it is better to buy a specialized profile for a specific Ariston model.
If you are in doubt about the choice, it is better to remove the old seal, measure its length and take a cross-sectional photograph of the profile so that a consultant in the store can help you choose an analogue. Exact match A profile is the key to a successful replacement.
Necessary tools and preparation of the workplace
To successfully replace the seal, you do not need complex professional tools, but you need to prepare the workplace in advance. You will need a hairdryer (construction or powerful household), as heating will make it easier to install new rubber and straighten out any creases that may have arisen during transportation. Also, stock up on a spatula or flat-head screwdriver to remove the old tape if it is secured in the groove.
Don't forget about cleaning products. Before installing a new part, the surface of the door and the groove for the seal itself must be degreased. Alcohol, acetone or a special glass cleaner are suitable for this. The rags must be clean and lint-free so that microparticles do not get under the rubber and break the seal. If the seal is secured with screws, prepare a Phillips screwdriver of the appropriate size.
☑️ Preparing to replace the seal
It is important to ensure good lighting of the work area. You will have to carefully monitor every millimeter of the perimeter so that no folds or gaps form anywhere. If you have a model with the system No Frost, be careful not to damage the sensors or wiring that may pass near the door frame.
Removing the old seal: step-by-step instructions
The process of removing the old rubber depends on the method of its attachment. In most modern models Ariston the seal is inserted into a special plastic profile (groove) on the inside of the door. Start from one of the top corners: carefully bend the edge of the rubber and, using a flat spatula or your fingers, pull it out of the groove. Move gradually around the perimeter, without making sudden jerks, so as not to deform the plastic edging of the door.
If you find that the seal is glued or screwed, proceed differently. The screws are usually hidden under a trim strip or on the inside of the door. In this case, partial disassembly of the inner door panel may be required. Carefully unscrew the fasteners, remove the old tape and clean the seating area from any remaining adhesive. Use a plastic scraper to avoid scratching metal or plastic.
⚠️ Attention: When dismantling old seals that have stood for many years, the rubber may crumble. Wear gloves and safety glasses to prevent crumbs from getting into your eyes or under your nails.
After removing the tape, thoroughly clean the groove. Grease, dirt and old glue residues often accumulate there. Perfect surface cleanliness is a guarantee that the new seal will fit smoothly and will work for a long time. Wipe the surface with alcohol and let it dry.
Installing a new seal and installation technology
It is recommended to warm up the new seal before installation. If it was lying rolled up or in the cold, it needs to be straightened out and heated with a hairdryer until warm (about 40-50 degrees). This will make the material more elastic and pliable. Start installation from the top corner of the door, inserting the profile into the groove. Move from the center to the edges, pressing the rubber tightly with your fingers so that it “sits” in the groove until it clicks or is completely immersed.
If the model involves fastening with screws, first attach the seal around the entire perimeter, align the corners, and only then tighten the fasteners. Do not tighten the screws all the way at once: go around in a circle, tightening them evenly. Pay special attention to the corners - these are the most problematic areas. The rubber should lie flat there, without creases or bulges.
After the entire contour is installed, check the fit again. Run your hand along the entire perimeter, feeling the joints. There should be no areas where the rubber “walks” or protrudes beyond the door. If you see gaps, try heating this area again with a hairdryer and pressing firmly.
Final check and elimination of defects
The final stage is quality control of the work performed. Test again with a piece of paper around the entire perimeter. Now the sheet should be difficult to remove at any point. If there is a gap left in some place, do not rush to redo the whole job. Often, local heating with a hairdryer and strong pressing of the door for 1-2 minutes is enough for the softened rubber to take the desired shape.
Turn on the refrigerator and leave it to work without loading food for 2-3 hours. During this time, the compressor will make several on and off cycles. Check for condensation and listen to the operation of the unit. A properly installed seal reduces the noise level, since the door fits tighter and vibrations are transmitted less.
Regularly, at least once every six months, wipe the seal with a soft cloth, soaked in soapy water and lubricate with silicone grease. This will prevent the rubber from drying out and cracking, maintaining its elasticity for many years. Preventive care will save you from the need for repeated repairs in the near future.
How often should you change the seal on the refrigerator?
B The average service life of a high-quality seal is 7-10 years. However, if the refrigerator is in a hot kitchen or next to a stove, the rubber may dry out faster. Change the part if cracks appear, loss of elasticity or loss of tightness that cannot be eliminated by adjusting the hinges.
Is it possible to restore the old seal instead of replacing it?
A temporary solution is possible: you can try heating the deformed areas with a hairdryer or using special rubber restorers. However, if the rubber is cracked or has lost its magnetic properties, these methods will only provide a short-term effect. A full replacement is the only reliable solution.
Why doesn’t the new seal fit right away?
New rubber is always stiffer than the old one and has “shape memory” from the packaging. It needs time to straighten out and take the shape of your door. Using a hairdryer during installation and tightly closing the door on the first day helps speed up this process.
