Causes of Liebherr refrigerator problems and do-it-yourself repairs

Doesn't freeze/doesn't work (refrigerator/freezer/upper compartment)

Most often the problem is a freon leak. If the chamber wall is swollen, then gas leakage occurs in the foamed circuit. It is no longer possible to correct such a defect. To be sure, you can try to defrost the refrigerator and then start it again. If there is no freon, the chambers will not cool.

If the freezer is equipped with a separate compressor, the temperature there will be normal. It is worth paying attention to the operation of the motor: if it turns on for a short time and stops with a roar, then it is time to contact the service department.

When there is only one compressor for both compartments, there may be several explanations for the malfunction:

The refrigerant switching valve is jammed, then the temperature in the freezer will rise, and freezing will begin in the cold cabinet.
In the refrigerator with No-Frost, the cooler, which ensures the flow of cold into the freezer, has broken down.
The temperature sensor has failed and the cold will not flow.
The control module has become unusable.

Liebherr does not freeze: reasons

Firstly, you need to clearly understand that, as with any other equipment with electronic filling, the uninterrupted operation of LIEBHERR refrigerators depends on stable network parameters. By connecting a refrigerator without a UPS, you take a big risk - the equipment can break down at any moment, so don’t skimp on stabilizers.

Secondly, it is worth answering the questions below - this will help you, when contacting a technician at a service center, describe the problem in as much detail as possible (in this case, the technician will be able to make a preliminary “diagnosis” and will take with him all the necessary tools to fix the problem).

So, if the Liebherr refrigerator has stopped freezing , evaluate the following points:

is there voltage present, is the corresponding indicator lit;
In the Liebherr refrigerator the freezer, refrigerator or both compartments do not freeze;
whether the refrigerator display is turned on, how it behaves - does it show errors or adequately fulfill your commands;
whether the compressor starts at least for a minimum time, whether it is turned off or whether it is working properly.

Doesn't turn on

When the lights and indicators are on in the refrigerator, but the refrigerator itself does not start or turns on for a short time, there are two possible reasons:

The starting relay is broken, this is indicated by the absence of characteristic clicks.

The compressor has failed. In case of a quick stop after starting.

When the device does not work at all - that is, there is no light inside, there is no indication and the control panel does not respond to pressing, then this means a complete blackout. Test the outlet using another electrical appliance. Another explanation could be a broken electrical cable. You need to examine it with a multimeter along the entire length from the plug to the junction box inside the device. If there is resistance when connecting between the compressor casing and the lead-through wires, then the problem is definitely in the compressor - it is faulty.

Possible causes of malfunctions of LIEBHERR refrigerators (Libherr)

Have you been using a German brand refrigerator for a long time, but recently noticed that the upper chamber has stopped freezing?

If the required temperature is not maintained in the compartment, but you hear the compressor humming, check whether the doors close tightly (the equipment may not be level, the problem may be in the sealing rubber), listen. These are the simplest and easiest to fix faults - but only if you do not ignore the problem and immediately contact the service center.
If the compressor operates but is idle (no temperature drop is observed), there may be a freon deficiency in the circuit. Listen, if you hear gurgling, most likely this is the cause of the breakdown.
If LIEBHERR (Libherr) does not freeze well , while the light in the compartment is on, the problem may be that the air sensor is broken - it does not signal the compressor to turn on. Solving the problem is not difficult - you just need to replace the temperature sensor.
Sometimes in Liebherr models the refrigerator compartment does not freeze well if the evaporator sensor, which is located in a compartment with a weeping wall, has failed.

If the freezer compartment in the LIEBHERR refrigerator does not freeze , the situation is more serious. If only because the problem may not be noticed immediately - we don’t open the freezer very often, so the desired temperature can be maintained autonomously here for at least a few more hours after the breakdown. What reasons can lead to the problem? Lack of freon, breakdown of the compressor or control system.

The set temperature is not maintained

There are many reasons why the temperature inside the refrigerator or freezer does not correspond to the set parameters:

Compressor failure - when it turns on for a few seconds and immediately turns off, and the temperature remains above the set temperature.

There is a problem with the fan motor of the “NoFrost” system or the bearing is jammed - ice has formed on the blades.

Malfunction of the thermostat or temperature sensor - the temperature in any department is significantly below normal, and the compressors operate frequently.

Freon leak - the compressor runs often, but there is no cooling.

Depressurization of the seal - it is warm inside the refrigerator, but the surface of the closed door is cold.

Quite often, the temperature regime is violated due to improper installation in a cabinet with insufficient ventilation.

Sound signal and indicator light turn on

The device can beep when the door is open or closed. In the first case, the sound signal indicates depressurization and insufficient cooling of the refrigerating chamber, which is caused by the following circumstances:

wear or deformation of the seal;
a door that is not tightly closed;
simultaneous placement of a large number of high-temperature products in the unit;
turning on the refrigerator for the first time.

If the following malfunctions occur, beeping sounds are heard even when the device door is closed:

Damage or icing of the damper that lets cold air into the refrigerator;
temperature sensor failure. The Alarm button lights up red, and the compressor runs constantly;
malfunction of individual elements or the entire defrosting system due to freezing of air ducts;
Freon leak. In addition to the squeaking sound, when such a malfunction occurs, the Alarm button begins to blink. It occurs as a result of a violation of the integrity of the pipes and the evaporator, which leads to an increase in the temperature inside the refrigeration chamber;
ECU failure caused by frequent voltage surges and moisture on the board. The beeping of the refrigerator is also accompanied by a red glow of the Alarm button;
problems with the compressor.

Such malfunctions should only be repaired by a specialist. Solving the problem yourself may lead to additional damage.

The temperature indicator starts flashing yellow when the ice maker breaks down (ice production continues, but the container is already full, the sensor does not perceive the presence of the container, the water inlet channel is frozen).

Ice maker not working

Some Liebherr brand refrigerators are equipped with a special device for producing clean ice - an ice maker. Like all mechanisms, it can fail. A flashing yellow light is a breakdown indicator and may indicate that:

The container presence sensor in the control unit is broken. Try swapping containers.

The water inlet channel froze. Defrosting with the door open and the freezer turned off helps.

The ice making mechanism is jammed when the container is full.

What to do if defrosting does not help?

In the remaining listed cases, you will need to call a technician to diagnose and replace parts.

Damage to motor and relay. The compressor starts and stops quickly, but oily traces are found under the Liebherr refrigerator? This means the problem is in the compressor. Oily fluid appears with slight decompression. Irregular operation and rapid shutdown indicate motor failure. If the compressor does not turn on at all, but clicks are heard, then the start relay has failed.
Uneven frost and swelling of the walls. Typical signs indicating a freon leak. If the freezer is positioned at the bottom, you may notice rusty stains on the body. This indicates a refrigerant leak through the freezer circuit. The drainage system becomes clogged, and moisture constantly accumulates in the upper part of the chamber or gets onto the front part. Over time, water begins to penetrate through the plastic covering the steel contour. It begins to rust and crack, resulting in a freon leak.
Damage to the temperature controller or temperature sensors. In Liebherr models with mechanical control, a regulator is installed that is responsible for the internal temperature. If it is damaged, the compressor simply does not start and the chamber does not freeze. In modern technology, thermal sensors are installed. If they fail, the system stops receiving information about the temperature in the chamber. The problem is solved by replacing them. The situation is more serious if the control unit (board) itself is damaged. The sensors may work fine, but the board does not process the received data.

Adjusting the door position

If periodic spontaneous opening of the door was noticed, then the reason is the weakened suction of it to the body of the device. The malfunction occurs due to the incorrect position of the door; it begins to sag, causing other breakdowns. If the problems are not corrected, the compressor or sensors will eventually fail.

The position of the doors can be changed using support brackets. Use a flat-head screwdriver to remove the cover. Then you need to unscrew the screws and adjust the position. The adjustment process takes place using grooves along which the door moves.

Correcting sagging should always be done by two people, as one person will not be able to hold the door and tighten the screws at the same time. In addition, the adjustment process should only take place using the level that the second participant must work with. Doing the work alone can simply damage the door. Troubleshooting Liebherr refrigerators

Although many breakdowns can be fixed on your own, some are still better left to a specialist. For example, replacing handles can be difficult for the average user. Therefore, it is better to use the services of a service center.

When replacing the seal, it is better to contact only professionals. Unfortunately, there is no separate original part for sale, so expert advice in selecting an analogue is necessary. Below are some problems that you should not attempt on your own.

What do the Latin letters on the display panel mean?

Refrigerators with electronic regulators are equipped with a system for displaying the nature of the malfunction.

To understand why the signal on the freezer is blinking, it is enough to read the error code that the device issued and compare it with the list in the product’s operating instructions.

If the Atlant refrigerator flashes a light and the letter of the error code is H, this means an increased temperature in the refrigerator or freezer compartment.
A signal with code L, on the contrary, means a decrease in temperature greater than the calculated one.
Codes with the letter F and a number to the right of it indicate a malfunction of a particular unit.

If an error with the letter F appears on the Atlanta panel, it is recommended to call a technician to diagnose the device.

Passing air through the elastic

Malfunctions in Bosch refrigerators are indicated by the letter E and a number to the right. Regardless of the code number, the device needs to be repaired.
