Refrigerators Ariston have earned a reputation as reliable equipment that can operate for years without serious failures. However, even the best quality units require attention to detail over time, and one of the most common problems is wear of the sealing rubber. It is this element that is responsible for the tightness of the chamber, keeping the cold inside and keeping the heat out. If you notice that the door does not close tightly or condensation has appeared on the walls, most likely it is time to replace the seal.
Many owners mistakenly believe that replacing rubber is a complex process that requires calling a technician and costly repairs. In fact, replacing the seal is a procedure available to any home craftsman with a minimal set of tools. The main thing here is to choose the right compatible part and carefully dismantle the old element so as not to damage the plastic of the door. In this article, we will look in detail at how to diagnose the problem and replace it yourself.
A timely response to seal wear will help avoid more serious breakdowns, such as compressor failure or the formation of an ice coat. Sealing rubber for Ariston refrigerators often has a specific profile of a magnetic insert, which is important to preserve when choosing an analogue. Ignoring small cracks can lead to significant waste of electricity and damage to food.
Diagnostics: when the seal needs to be replaced
You can determine that the sealing rubber on your Ariston refrigerator requires replacement based on a number of visual and functional signs. The first alarm bell is often a loose fit of the door: if there is a gap between the chamber and the seal, cold air begins to actively evaporate. This leads to the fact that the compressor is forced to work in increased mode, trying to compensate for temperature losses.
Visual inspection can also reveal mechanical damage. Over time, rubber loses its elasticity and becomes hard and brittle. Microcracks may appear on the surface through which heat exchange occurs. If you run your hand over the seal and feel sticky, or see that it has become deformed and no longer straightens when pressed, this is a sure sign that it needs to be replaced.
There is a simple and effective method for checking the seal, known as the “paper test”. You will need a regular sheet of A4 paper. Open the refrigerator door, place the sheet on the gasket and close the door. Try to pull out the sheet: if it pulls out easily and without resistance, it means tightness is broken. Carry out this test along the entire perimeter of the door, as wear can be local.
⚠️ Attention: If during a visual inspection you find mold or black deposits in the folds of rubber that cannot be removed by cleaning, replacement is required. Mold spores can spread inside the chamber and land on food.
Choosing a suitable seal for Ariston
The spare parts market for household appliances offers many options for seals, but for refrigerators Ariston it is important to choose exactly the modification that matches your model. Seals differ not only in size, but also in the type of fastening, the shape of the magnetic insert and the angle of the profile. Incorrectly selected rubber may not fit into the groove or, on the contrary, may dangle, which will negate all repair efforts.
The first thing to do is to find the technical data sheet of the refrigerator or a sticker with the model range, which is usually located inside the chamber or on the back wall. Knowing the exact model (for example Ariston MBA 2185 or Ariston RF 36), you can order an original spare part or a high-quality analogue. Original seals are often more expensive, but guarantee a perfect fit and durability.
When choosing between the original and the analogue, pay attention to the material. High-quality rubber should be soft, without a strong chemical smell. Cheap substitutes can quickly become stiff in the cold or, conversely, melt when heated. It is also important to consider the number of chambers: two-chamber models often require different seals for the freezer and refrigerator compartments.
| Seal type | Compatibility | Average service life | Installation features |
|---|---|---|---|
| Original Ariston | Accurate for a specific model | 7-10 years | Perfect fit in the standard groove |
| Universal (for cutting) | Requires fit | 3-5 years | Complicated installation, corners need to be cut |
| Analogue (China/Turkey) | Group of models | 4-6 years | Small gaps are possible |
| Repair kit | For minor damage | 1-2 years | Adhesive base, temporary solution |
If you are not sure of the choice, it is better to contact a specialist or consultants of specialized stores, providing them with a photo of the old seal and the markings of the refrigerator. Sealant profile is a critical parameter that determines how tightly the door will fit to the body after installation.
Necessary tools and preparation
Before proceeding with direct replacement, it is necessary to prepare a workplace and tools. Replacing the seal on the refrigerator Ariston does not require complex equipment, but accuracy and the presence of the right tools will greatly simplify the task and prevent damage to the plastic.
- 🔧 Screwdriver or screwdriver - you will need cross and flat bits to dismantle the inner door panel if the seal is hidden under it.
- 🔨 Plastic spatula or spatula —necessary for carefully removing old rubber from the groove without scratching the body.
- 🧼 Detergent and degreaser —to clean the mounting channel from dirt, grease and old residues glue.
- 🌡️ Hair dryer —will help soften the new seal before installation, making it more elastic.
- ✂️ Scissors or utility knife —may be needed to trim excess or adjust corners.
Preparing the refrigerator also includes defrosting it. Although complete defrosting is not always necessary, if you are changing the seal on only one door, it is recommended to unplug the unit for at least 30-40 minutes. This will make the plastic more pliable and reduce the risk of breaking under mechanical stress. In addition, it is better to remove the products so that they do not interfere with visibility and access to the perimeter of the door.
Ensure good lighting of the work area. You will have to carefully monitor every centimeter of the perimeter to make sure that the rubber lies flat and no folds have formed anywhere. Cleanliness of the channel is the key to successful installation, so take the time to thoroughly clean the joint.
☑️ Preparation for replacement seal
Step-by-step instructions for dismantling the old seal
The process of removing the old seal depends on the type of fastening used by the manufacturer Ariston. In most modern models, the rubber seal is either glued into a special groove or pressed against a plastic panel on the inside of the door. In some cases, there may be a combined fastening option.
If the seal is held on by screws hidden under the plastic, you will have to remove the inner door lining. To do this, carefully unscrew all visible screws around the perimeter and in the center. Proceed with caution: plastic latches can be fragile, especially if the refrigerator has been in use for a long time. After removing the panel, you will see how the edge of the rubber is fixed in the channel.
In the case when the seal is simply inserted into the groove, start pulling it from one of the upper corners. Use a plastic spatula to pry up the rubber and gradually pull it out all the way around. Do not use metal tools as they may damage the plastic or scratch visible parts of the case. If the rubber is glued, heat it with a hairdryer - this will soften the adhesive layer and make dismantling easier.
⚠️ Attention: When removing the inner door panel, be careful with the freon supply tubes if they pass inside the door leaf. Do not use excessive force to avoid pinching or damaging the lines.
After completely removing the old rubber, thoroughly clean the surface. Remove any remaining adhesive, dust and grease. To do this, you can use warm water with a mild detergent and then wipe the surface with alcohol or a degreaser. A clean and dry surface will ensure better adhesion of the new seal or its tight fit in the groove.
What to do if the old seal breaks during removal?
If the rubber comes off in pieces, do not panic. The main thing is to completely clean the canal of all residues. Sometimes fragments of magnetic tape or glue may remain inside the groove, which must be removed, otherwise the new seal will not fit smoothly. Use tweezers to remove small parts from hard-to-reach places.
Installing a new seal on the refrigerator
Installing a new seal is the most critical stage of the work. Before starting installation, it is recommended to lay the new seal flat out at room temperature for several hours, and then lightly warm it with a hairdryer. This will make the material more flexible and make it easier to fit into corner joints.
Start installation from the top corner of the door. Insert the edge of the seal into the groove or attach it to the mounting location. If using a screw fastening, secure the corners first, then the middle of the sides, and only then go around the entire perimeter, tightening the remaining screws. Movements should be smooth, without jerking, so as not to stretch the rubber unevenly.
If the seal is inserted into the groove without screws, use a blunt object (for example, the handle of a screwdriver or a special tool) to firmly push the edge of the rubber into the channel. Move from corner to corner, controlling the tension. It is important that the seal is not pulled too tight, otherwise it will begin to move away from the body, but there should not be any sagging.
Pay special attention to the corners. This is where cracks most often form. Make sure that the rubber is folded neatly in the corners, without creases or voids. If the seal profile involves joining in the corners, ensure that the ends are connected accurately. After installation, walk your hand along the entire perimeter, checking the tightness of the fit.
Quality check and first start
After the new seal is installed, do not immediately load the refrigerator with food and close the door tightly. Give the technology and new tires time to adapt. Plug in the refrigerator and leave it idle for at least 2-3 hours. During this time, you will be able to check the operation of the unit and the quality of the installation.
Carry out a repeat “paper test” around the entire perimeter. Now the sheet should be pulled out with noticeable effort and the same resistance at all points. Visually inspect the joint: there should be no visible gaps, gaps or places where the rubber is bristling. The door should close with a characteristic soft pop, but not require excessive force to slam.
On the first day of operation, listen carefully to the sounds of the operating compressor. If your refrigerator is humming louder than usual or the on/off cycles are becoming too frequent, this may indicate that the seal is still compromised. Also check the side walls of the refrigerator - they should not get too hot, which happens when the motor is constantly running due to cold leakage.
- ✅ Uniform fit - there are no gaps around the entire perimeter.
- ✅ Test with paper - the sheet is clamped tightly and evenly.
- ✅ Stable temperature —the refrigerator quickly gained cold and keeps it.
- ✅ No condensation —it’s dry inside, there are no drops of water on the walls.
⚠️ Attention: If, after replacing the seal, the door begins to close tightly or, conversely, does not hold, the seal may be installed incorrectly or is not the right size. In this case, the procedure will have to be repeated, possibly with replacement of the part.
Why can a new seal smell?
New rubber always has a specific smell, which is the norm for polymer materials. It should dissipate within a few days of running the refrigerator. To speed up the process, you can wipe the seal with a weak solution of vinegar or lemon juice, but do not use aggressive chemicals.
Frequently asked questions (FAQ)
Is it possible to glue the old seal if it has simply come off?
If the rubber is intact, elastic and not has cracks, you can try gluing it. For this, special glue for rubber or “Moment” is used. However, this is a temporary measure: over time, the glue will dry out and the problem will return. It is better to replace the seal completely.
How often do you need to change the seal on an Ariston refrigerator?
The average service life of a high-quality seal is 5-7 years. However, with intensive use, frequent opening of the door or exposure to direct sunlight, replacement may be required earlier - after 3-4 years.
Why did the door become harder to open after replacing the seal?
This is normal for a new seal that has not yet been developed. Strong suction is created due to perfect tightness and the operation of magnets. After 1-2 weeks of operation, the rubber wears out a little, and the opening force will become comfortable.
Can a universal seal be used instead of the original?
Universal seals require complex adjustment and are often inferior in terms of tightness. For refrigerators Ariston it is better to look for original spare parts or proven analogues that exactly match the model to avoid problems with temperature conditions.
What to do if there are small gaps in the corners?
Small gaps in the corners can be tried to be eliminated using a hair dryer: heat the problem area and press the door tightly against several hours. If this does not help, the seal may be selected incorrectly or installed skewed, and the procedure will have to be redone.
