If your Liebher refrigerator does not work, do not despair - you need to look for the cause of the breakdown. Modern technology can display an error code on the display, but if there is none, we will help you figure out the malfunction.
Liebher refrigerator manufacturers have created an expensive and reliable home appliance that undergoes strict quality control, only when it is included in our network it starts to fail. Consider why this is happening.
Typical Liebher Refrigerator Problems
The more technology and electronics introduced into household equipment, the more sensitive it is to network problems. Incorrect installation and operation contribute to the work of Liebherr. Let's see which failures users complain most often.
The refrigerator does not work in the refrigerator
Is the compressor humming but there is no cold in the chamber? Need to take action. Due to overloads, the freezer may also fail, resulting in costly repairs. The main problem is the storage of products, because with a faulty refrigerator they will quickly deteriorate.
What you need to check first:
- Is the camera door tightly closed? Due to the overcrowded compartment, closing the door may interfere with something. Move pots and pans out of the way.
Check door seal. If it does not fit well with the case, it must be replaced or put in order. Hot water will help straighten the rubber, restore its shape. Water the seal around the perimeter from the kettle, straighten it straight away. - Check the temperature in the chamber. When the room is hot, the refrigerator has a maximum temperature, the compressor cannot cope with the load. Decrease reading - stop at 2.5.
- Inspect the fan if you have a Nou Frost cooling system. When the fan does not work and ice forms on its blades, you need to urgently defrost the refrigerator. In No Frost, it is the fan that is responsible for the distribution of cold air in the chamber.
Defrosting did not help resume the operation of the equipment? So, it's a malfunction. You can determine the breakdown by external signs:
- After defrosting the chamber, the fan did not start working. Check its motor - it may have burned out and a replacement is required.
- In addition to the fact that the fan blades do not rotate, snow has formed on the compartment walls. The wall behind which the evaporator is most frozen. Evaporator heater defective; defrost in refrigerator does not turn on. Therefore, snow and ice accumulate on the walls.
- The freezer is very cold, the walls are covered with ice. The motor compressor runs without rest. Signs indicate problems with the temperature controller in the freezer, so cold air does not blow into the refrigeration section.
- Refrigerant leakage may cause bloating. If leakage occurs through the steel circuit, rust smudges on the housing will be visible. With mechanical damage to the wall, gas escape is also possible. A specialist will help eliminate the leak and refill the system with freon.
- Damage to the temperature controller or air sensor of the refrigerator compartment. Therefore, the board does not receive a signal of an increase in temperature, so the cooling does not turn on. Need replacement parts.
Take a close look at your fridge. Perhaps these symptoms will help you find the problem.
The freezer does not work in the refrigerator
Since we do not look into the freezer so often, you may immediately not notice a malfunction. However, if blocks of ice froze on the walls of the cell, and a puddle of water gathered near the XO, you need to beware.
Immediately check the tightness of the door seal. If it lets warm air through, then the system will compensate for the temperature increase. When the compressor is turned off, frozen snow will begin to melt.
It also happens that the freezer does not work at all. Then pay attention to the signs of damage:
- The freezer motor runs for several seconds and turns off. Faulty compressor. As a result of the excess load, there is a rapid deterioration of the motor parts, so a device replacement will be required.
- The engine runs normally, but does not start for a long time after shutdown. This indicates a problem with the air sensor or temperature controller. The electronic module does not receive information about the temperature in the chamber; therefore, it does not give a command for cooling.
- If the switching valve is jammed, then the freezer will not cool the products well, because there is not enough power for normal freezing. Need valve replacement.
- With a gas leak, it becomes less, so it is not enough for the normal operation of the system. It will be necessary to eliminate the leak and fill the system with freon.
- If the control module breaks down, there may be no additional signs. The camera may not work, the lights and bulbs on the panel may not light. Probably, the breakdown occurred due to a short circuit, which damaged the elements of the board or its wiring. The wizard will diagnose, replace, or upgrade the module.
To determine exactly the causes of the problem, some external signs are not enough. It is necessary to conduct a complete diagnosis of the equipment.
The refrigerator works loudly when turned on
The loud operation of the refrigerator not only interferes with the user, but also can harm the equipment. If you are convinced that the noise values are above normal, start troubleshooting.
- The correct installation. When the body is warped, an additional load is placed on the engine, which makes it work with a vengeance and noise. Set the XO level, adjust the position of the legs. The equipment should not stand close to a wall, battery or other furniture.
- Shipping bolts. If you just brought and installed the equipment, you may have forgotten to remove the bolts that fix the position of the motor. They must be removed, otherwise it will lead to wear of parts.
- The location of the dishes. Probably rattling dishes on the shelves when the two containers are in contact. Change the location of the pots.
- The freezing of snow and ice on the walls of the compartment leads to a double operation of the motor. If freezing occurs on one wall, an imbalance of the housing occurs. For this reason, the refrigerator may buzz and jump when turned on. It is necessary to completely defrost the equipment within 10 hours.
- Loose engine mounts. Since shock absorbers are used to absorb vibrations, when their mounts are loosened, hum and rattle of the compressor are poorly drowned. It is necessary to tighten the fasteners.
More serious causes include problems with the motor-compressor and fan noise. The latter can be overgrown with snow, which leads to a rattle during the rotation of the blades.

Be attentive to your technique, and it will thank you with a long work. You only need to adhere to the manufacturer's recommendations, carry out preventive defrosts, wash shelves and compartments. Protecting the electronic part is equally important - connect the refrigerator only to grounded outlets so that it does not break.
