Owners of premium appliances are often faced with the need to change the configuration of the kitchen space, which requires re-hanging the door refrigeration equipment. Models Liebherr are famous for their reliability and thoughtful engineering, but even in them, over time, they may require replacement hinges or the sealing rubber. Doing this work yourself allows you to save significant money on calling a specialist if you strictly follow the technological regulations.
The process of dismantling and installing the door leaf requires care, since the components are heavy and have a complex design. Incorrect actions may cause damage facade or loss of seal to the camera. In this article we will analyze in detail the stages of work, the necessary tools and nuances characteristic of the German brand.
It is worth noting that the design of the hinges may differ depending on the series - CBN, CN, CTP or built-in models. Before starting any manipulations, it is strongly recommended to study the technical data sheet of your device, which indicates specific tightening torques types of fasteners. Ignoring this data may cause the canvas to skew.
Preparation of the workplace and necessary tools
High-quality door replacement is impossible without proper preparation. You will need not only a set of tools, but also free space for maneuver, since the dimensions of the equipment Liebherr often exceed standard ones. Make sure the floor is level and there is sufficient lighting to work with small parts.
The basic set of tools should include:
- 🔧 A set of screwdrivers (phillips and flat) for various types of screws.
- 🔩 Socket wrenches or sockets (usually 8, 10, 13 mm) for hinge bolts.
- 🧤 Protective gloves and soft rags to protect the surface.
- 📏 Level and tape measure to control the installation geometry.
Pay special attention to the condition of the fasteners. If you plan to move the door to the other side, check that all necessary plugs and screws are included in the delivery kit, which is usually stored in packaging container. The absence of even one small screw can stop the entire process.
⚠️ Attention: Before starting work, be sure to disconnect the refrigerator from the power supply! This is critically important for safety, since some models have backlighting and electronic modules that are energized even when the door is closed.
☑️ Checking readiness for operation
Removing the top panel and top hinge
The first step is always removing the top decorative cover, if it is structurally provided for in your model. Liebherr. It can be secured with latches or screws hidden under decorative plugs. Proceed carefully so as not to break the plastic fasteners, which become brittle in the cold.
After removing the cover, access to top hingeopens. It is she who bears the main load of holding the canvas. Before unscrewing the bolts, you must lock the door in the closed position or ask an assistant to hold it. A sudden tear of the canvas can lead to injury or damage to the floor covering.
Use a socket wrench to unscrew the bolts securing the hinge to the refrigerator body. Do not apply excessive force if the bolt does not fit - the threads may be soured and require treatment with a penetrating lubricant. Carefully remove the hinge and set it aside.
Liebherr fastener nuances
In some models, the top hinge can be integrated with the closer mechanism. In this case, dismantling requires special care so as not to damage the spring mechanism. If you hear a characteristic click or feel the resistance of the spring, it is better to stop and consult the diagram in the manual.
Removing the door leaf and the lower hinge
After releasing the upper support, the refrigerator door Liebherr is held only by the lower hinge. This is the most crucial moment of dismantling. The weight of the door leaf with shelves can reach 30-40 kilograms, so it should only be removed with a reliable support or the help of a second person.
Carefully lift the door to remove it from the lower axis and place it on a previously prepared soft surface (for example, a blanket or cardboard). The front side should face up so as not to scratch enamel or the coating SmartSteel. Now you can begin dismantling the lower hinge.
Unscrew the bolts of the lower hinge and remove it. If you are replacing the door completely, then at this stage you can remove the old handles, magnetic seals and internal shelves from the dismantled leaf, moving them to the new door. Pay attention to the condition of the bushings and washers - it is also better to replace them.
The table below will help you navigate the types of fasteners for different series:
| Liebherr series | Type of upper hinge | Fixing the lower hinges | Feature |
|---|---|---|---|
| Liebherr CBN | Hidden, 3 bolts | Axle with washer | Requires removal of the base |
| Liebherr CN | Open, 2 bolts | Threaded bushing | Standard access |
| Liebherr IC | Integrated | Complex mechanism | For built-in models |
⚠️ Attention: When removing the door, watch the wires if your model Liebherr display or touch panel is located on the door. They must be carefully disconnected, first remembering or photographing the connection diagram.
Installing a new door or rehanging it on another side
Installation is carried out in the reverse order of dismantling. If you are installing a new door, make sure it is complete. When rehanging to the other side, it is necessary to rearrange all fastening elements (handles, stops) to the opposite holes provided by the design Liebherr.
Start by installing the bottom hinge. Insert the axle or screw the pad to the body, keeping it horizontal. Slide the door panel onto the bottom axle, making sure it is snug in place. Only after this can you begin installation of the upper hinge.
Screw the upper hinge to the body, but do not tighten the bolts all the way yet. This will allow you to pre-adjust the door position. Make sure that the gaps around the perimeter are uniform and that the door itself is not skewed relative to the horizon.
Adjusting the position and tightness of the fit
Correct adjustment is the key to long service life of the compressor and saving energy. The refrigerator door Liebherr should close tightly, but without excessive force. If the door is skewed, it will not fit tightly to the body, which will lead to the formation of stick ice.
To adjust, use the adjusting screws on the hinges (if they are provided in the model) or the method of placing washers. By rotating the adjusting bolts, ensure that the upper and lower clearances are the same. Check the operation of the magnetic seal around the entire perimeter.
Carry out a test with a sheet of paper: clamp the sheet between the door and the body at different points. It should be removed with noticeable force. If the sheet falls out or is pulled out too easily, it is necessary to tighten the hinges or replace seal.
⚠️ Attention: Do not allow the door to skew by more than 2 mm. In models Liebherr NoFrost this may lead to the air duct damper not opening completely and the temperature in the chamber no longer meeting the set temperature.
Replacing the magnetic seal (rubber band)
Often, door replacement is not required; it is enough to replace the worn seal. Old rubber loses its elasticity and no longer holds the cold. In refrigerators Liebherr the seal is usually attached to a special groove around the perimeter of the door.
Carefully pull the old seal out of the groove, starting from one of the corners. Clean the channel of any remaining adhesive, dirt and grease using a mild detergent. The new rubber band should be at room temperature - before installation, it is recommended to keep it in a warm room for several hours or slightly warm it with a hairdryer (without overheating!).
Insert the new seal evenly around the entire perimeter, starting from the top corner. Make sure that the magnetic tape fits tightly into the groove and does not protrude anywhere. After installation, let the door stand closed for several hours to straighten the material.
Checking functionality after installation
After completing all installation work and final tightening of the bolts, it is necessary to check the functionality. Plug in the refrigerator and let it run idle for 2-3 hours. Monitor how often the compressor turns on.
Check the operation of the door open alarm. If your model Liebherr has an indication, make sure that it lights up when opening and goes out when closing. Lack of response may indicate a malfunction of the magnetic sensor or problems with the wiring.
Visually inspect the joints and hinges after a day of operation. Has condensation appeared or the level has gone down? If all the parameters are normal, you can load the products.
Is it necessary to let the refrigerator sit after transportation before replacing the door?
If the refrigerator was just standing in the room, no additional time is required. However, if the device has just been brought from the cold or was actively shaken during transportation, it is recommended to allow the oil in the compressor to settle for 2-4 hours before turning it on.
Is it possible to replace a metal door with a glass one in Liebherr models?
Replacing the type of door is only possible if the design of the body and hinges are designed for different weights. Glass doors are heavier and standard hinges may not be able to handle the load, causing them to break. Consultation with an official service is required.
Why did the refrigerator begin to hum louder after replacing the door?
Most likely, the geometry of the installation is broken. The door may touch the housing or internal components when the compressor vibrates. Also check if the refrigerant tube going to the door is twisted (in models with a display or a freshness zone on the door).
