Replacing the rubber seal on a Liebherr refrigerator: instructions with photos and videos

Sealing rubber (or door seal) is the key element responsible for the tightness of the refrigerator Liebherr. Over time, it loses elasticity, becomes cracked or deformed, which leads to increased energy consumption, ice formation and even compressor failure. If you notice that the door does not fit tightly, and condensation appears inside the chamber, it’s time to think about replacing.

In this article we will look in detail at how change the seal yourself on refrigerators Liebherr (including popular series PremiumNoFrost, BioFresh i Comfort). You will learn how to choose the right rubber band, remove the old one without damage and install a new one with a perfect fit. And also - which hidden fasteners are used by Liebherr in models after 2020that are not written about in standard instructions.

The procedure does not require special skills, but it is important to follow the algorithm and avoid typical errors. For example, many users do not tighten the seal in the corners correctly, which leads to repeated leaks within a month. We will show you how to avoid this.

Signs of wear on the sealing rubber

The first signal that the seal requires replacement is constant formation of ice on the back wall or condensation on the shelves. This occurs due to warm air entering the chamber. Other obvious signs:

The door closes with a characteristic “pop” or, conversely, remains ajar. In some models Liebherr (for example, CNef 4815), this triggers a sound signal about loose closure.

• 🔍 Visible cracks or tears on the surface of the elastic, especially in the corners.
• 💧 Moisture on the seal - if it is constantly wet, this is a sign of a leak.
• ❄️ Ice on the back wall even when the system is working correctly NoFrost.
• 📈 Increased energy consumption (check the meter or data in the mobile application Liebherr SmartDevice).

A less obvious, but important symptom - uneven coolingIf the food in one corner of the chamber freezes and spoils in the other, the problem may be in the seal. It’s easy to check: take a sheet of paper, close the door and try to pull it out. If the sheet comes out without effort, the rubber does not do its job. function.

In models with BioFresh seal wear is especially critical: disturbance of the microclimate in the freshness zone leads to spoilage of fruits and vegetables after 2-3 days.

Choice of seal: original vs analogs

For refrigerators Liebherr manufacturer. recommends using original sealswhich are sold under article numbers corresponding to the model. For example:

• 7061250 - for series PremiumNoFrost (CNes, CNef);
• 7061251 - for models with BioFresh (SBnes, Sbses);
• 7061252 - for built-in refrigerators (IK, IU).

Original rubber bands are made of food-grade silicone with antibacterial impregnation, which guarantees a long service life (up to 10 years). However, their cost can reach 5-8 thousand rubles. Alternative - universal. seals from trusted brands:

• 🔹 Sibir (Russia) - budget option, suitable for 80% of models Liebherr;
• 🔹 Midea (China) - middle price segment, good elasticity;
• 🔹 Indesit (Italy) - premium quality, but requires adjustment to size.

When choosing an analogue pay attention to:

1. The thickness and width of the profile —must match the original (±1 mm).
2. Type of fastening: inserted (“herringbone”), adhesive or self-tapping (in older models).
3. Color — Liebherr seals come in grey, black and white (for example, in the series Blizzard).

⚠️ Attention: In models Liebherr after 2018, the seals are equipped with a magnetic insert for a better fit. When When purchasing an analogue, make sure that it is also magnetic, otherwise the door will close with a click.

Preparation for replacement: tools and safety

Before starting work unplug the refrigerator and empty the door of food. If the model is with NoFrost, wait for complete defrosting (2-4 hours). To replace the seal you will need:

• 🔧 Flat screwdriver (to remove the old rubber band).
• 🔨 Spatula or plastic spatula (to pry off the fastener).
• 🧴 Silicone grease (for example, WD-40 Specialist) to facilitate installation.
• 📏 Tape measure (for checking the length of the new seal).
• 🧲 Magnet (for testing the magnetic insert in new models).

If the seal is attached to self-tapping screws (relevant for refrigerators Liebherr till 2015), prepare a Phillips screwdriver or a screwdriver. In modern models, plastic clips or are used. herringbone system, which do not require tools for dismantling.

Be sure to take a photo initial position of the seal (especially in the corners) - this will help to install the new one correctly If the door is heavy (for example, in the models Side-by-Side), fix it in the open position using a rope or a special holder.

⚠️ Attention: Do not use a knife or sharp objects to remove the old rubber - this may damage the plastic door body. In models Liebherr Premium the body is covered. anti-scratch layer, which is easy to scratch.

Removing the old seal: step-by-step instructions

Removing the worn rubber band is the most important step B. models Liebherr the seal can be attached in three ways:

1. In a groove (“herringbone”) —the most common option (series Comfort, Premium).
2. On self-tapping screws —in older models (before 2010) and some built-in ones.
3. On glue —rare, but found in budget series (for example, TP).

For herringbone fastening:

1. Carefully pry the edge of the seal with a flat screwdriver or spatula.
2. Pull the elastic towards you, gradually releasing it from the groove. Start from the top corner - the fastening is usually weaker there.
3. There may be hidden plastic doors in the corners (in models after 2020). clips hidden plastic clips (in models after 2020). They need to be squeezed with your fingers and pulled out.

For fastening with screws:

1. Unscrew all the screws (usually there are 8-12 around the perimeter).
2. Remove the seal, clean the holes from dust.
3. Check the thread - if it is damaged, use self-tapping screws of a larger diameter.

If the gum is glued, it must be carefully cut off with a stationery knife, and the remaining glue must be removed with a solvent (for example, White spiritDo not use acetone - it can damage the plastic. Liebherr.

What to do if Is the seal stuck?

In old refrigerators (especially in models Liebherr 90s), the rubber band may “stick” to the body due to oxidation. In this case:

1. Heat the problem area with a hairdryer (temperature no higher). 80°C).

2. Pry up the rubber with a plastic spatula, without using excessive force.

3. If that doesn’t help, use a special seal remover (sold in auto parts stores).

Installing a new seal: the secrets of an ideal seal. fit

Before installation check the new seal to match the size. To do this, attach it to the door - it should exactly follow the contour, without tension or sagging. If the elastic is longer, it can be trimmed with scissors (but no more than 2 cm).

For herringbone fastening:

1. Start from the top corner. Insert the edge of the seal into the groove and gently press it along the entire perimeter.
2. In the corners, use plastic spatulato evenly distribute the tension.
3. Check that the rubber is not twisted - this is a common mistake when replacing it yourself.

For fastening with screws:

1. Attach the seal to the door and mark with a pencil the places for the screws.
2. Do not tighten the screws all the way to avoid deformation of the elastic.
3. Start from the top corner and move clockwise.

After installation heat the seal with a hairdryer (temperature 50–60°C) - this will help it take the correct shape In models with a magnetic insert. check the force of attraction: if the door closes too easily, the magnet may be installed incorrectly.

Leak test:

1. Close the door and try to open it using the seal - if the rubber does not come off, the seal is normal.
2. Place the switched-on flashlight inside the chamber. In the dark, no light from outside should be visible.
3. Use test with paper: the sheet should hold when pressed with the door.

⚠️ Attention: B refrigerators Liebherr with a system BioFresh have a seal on the bottom door (freezer compartment) double circuit. When installing, make sure that both parts of the elastic fit tightly to the body.

Common mistakes and how to avoid them

Even with careful replacement, you can make mistakes that will negate all your efforts. Here are the most common:

• ❌ Using a non-original rubber band without fit —leads to cracks and leakage.
• ❌ Uneven tension —the seal must be tensioned equally around the entire perimeter.
• ❌ Ignoring the magnetic insert —in new models without it, the door will not close tightly.
• ❌ Use of force during installation —this can deform the groove or the rubber itself.

Another typical problem is door misalignment after replacing the seal. This happens if the elastic is installed asymmetrically. To avoid misalignment:

1. Check that the seal protrudes equally around the entire perimeter (the permissible difference is no more than 1 mm).
2. Use level to check the horizontal position of the door.
3. If the door sags, adjust the hinges using a hex key (instructions are in the user manual).

In models Liebherr with NoFrost after replacing the seal, the operating time may temporarily increase compressor. This is normal - the refrigerator needs 1-2 days to restore the optimal temperature.

Care sealant: how to extend its service life

To make the new seal last longer, just follow a few simple rules:

• 🧼 Regular cleaning —wipe the rubber with soapy water (once a month) Do not use abrasive products!
• 🧴 Grease - once every six months, apply silicone grease to the seal (for example, WD-40 Specialist).
• 🚪 Closing carefully - do not slam the door, this will deform the rubber.
• ☀️ Sun protection —if the refrigerator is facing the window, use curtains or UV protection film.

In models with BioFresh the freezer seal is especially vulnerable due to frequent opening. To reduce the load, use door organizers - they reduce the number of openings.

If the seal begins to stick or become moldy, treat it vinegar solution (1:1 with water will help antibacterial spray for refrigerators (For example, Top House).

⚠️ Attention: In refrigerators Liebherr with function SmartFrost the seal has a special coating that may be damaged by aggressive detergents. Use only mild alcohol-based cleaners.

FAQ: answers to frequently asked questions

Is it possible to repair a seal without buying a new one?

If the rubber is is torn in one place, it can be temporarily repaired using silicone sealant (for example, Moment. Germent). However, this solution is only suitable for small cracks (up to 2 cm). A full repair will require replacement.

In cases where the seal has lost its elasticity, it can be restored by immersing it in hot water (60–70°C) for 10–15 minutes. But the effect will last no more than 3–6 months.

How to understand that the seal is installed incorrectly?

Basic signs:

• The door closes with force or, conversely, too easily.
• Condensation appears on the walls of the chamber.
