Liebherr refrigerator: breakdowns, their causes and 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:

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.

Liebherr refrigerator fault instructions

If a breakdown occurs, the Alarm button located on the electronic panel begins to flash. If you press it, error codes are displayed on the display indicating the nature of the malfunction. Their meaning can be found by reading the instructions for the unit:

• F0 – malfunction of the biosensor responsible for the temperature level in the zero chamber;
• F1 – the air indicator of the refrigerator compartment is faulty;;
• F2 – evaporator sensor has failed;
• F3 – problems with the freezer air sensor;
• F4 – problem with the evaporator sensor in the freezer;
• F5 – the control module has failed;
• F7 – problem with the external temperature sensor;
• ND – damage to the control board or network cable.

The solution to such problems is to replace faulty sensors.

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:

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.

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:

Types of breakdowns in Liebherr equipment

Problems that appear in any refrigerator can be divided into two groups: implicit (hidden) and obvious. The first group includes symptoms that appear, ignoring which will lead to more serious problems. The second category of breakdowns is easily identified by the inscription of the electronic display.

Hardware failure

This type of malfunction is the most popular among Liebherr refrigerators, which appears 3-4 years after purchase. It depends on the force and frequency of opening the door. Door fastenings and shelves can break, but only after 5-6 years of use. If such breakdowns are not repaired in a timely manner, there is a high risk of leakage and intense compressor operation;

Problems with light bulb light bulb

The light in the main compartment or freezer does not light up or does not turn off. A common cause of violations is a burnt-out light bulb, which you can purchase and change yourself. The breakdown can also be the result of a broken breaker, where professional help will be required;

Alarm light flashing

The Alarm light flashes when the temperature drops as a result of a broken sensor, leaks from a foamed area or a broken motor-compressor. In this case, troubleshooting will be based on replacing the necessary sensors;

Ice freezing

Ice freezing in the Liebherr refrigerator. The appearance of a coat of ice on the back wall of the unit may indicate that a pan that has not cooled down is installed inside or the door is not tightly closed. Due to the very dense loading of the chamber, increased compressor operation and the appearance of ice deposits may also be observed;

Non-stop operation of the motor-compressor

Non-stop operation of the motor-compressor. This can occur as a result of a clogged dryer filter or refrigerant leakage from cracks formed. Additionally, you can determine that the device is not freezing;

Appearance of liquid

The appearance of fluid in the lower part of the main section. If liquid appears under the meat and vegetable drawers, the cause of the problems may be a clogged drainage system. When a special hole in the lower part of the refrigerator compartment is filled with cans and food, then within a few years it will be clogged with dirt, after which water will not flow into the drain;

Compressor replacement

When replacing a compressor, a new mechanism is installed that matches the characteristics of the cooling system. At the same time, the coincidence of the operating zones of the compressor is checked, the frequency and voltage correspond to the network indicators, and the cooling condition is taken into account. In this case, it is better to entrust refrigerator repairs at home to a reliable company that supplies original spare parts.;

Replacing the thermostat

If the compressor does not turn on or works without interruption, but the temperature in the upper chamber is more or less than optimal, setting the maximum value of the thermostat knob does not bring optimal results, then the thermostat is broken and requires replacement;

Leak Removal

Removing leaks in a foamed area and breaking down a crying evaporator. With Liebherr units, freon may leak in the foamed part due to a breakdown of the weeping evaporator. This may occur as a result of an increase in temperature. But you don’t need to fix freon leaks yourself;

Changing the seal

The seal is important in maintaining low temperatures in the freezer and refrigeration sections. Due to damage to the sealing rubber, the temperature of the chambers increases, there is an additional load on the compressor and its service life is reduced. Due to the fact that replacing or repairing a compressor is considered expensive, you need to check the tightness of the rubber around the perimeter of the refrigerator chambers and doors and install the doors correctly;

Fan failure

A long-standing device in Liebherr refrigerators is designed to distribute cold air inside the freezer and refrigerator compartment, which is often placed behind the air cooler. If it breaks down, there is no air supply to the chambers, ice and frost freezes on the walls;

Failure of the Liebherr electronic module

The device controls the operation of refrigerators, the program of which contains information about temperature, humidity and various modes. Correct operation depends on the electronic module, but as a result of voltage surges or network short circuits, it may fail and must be replaced with a new part;

Heater malfunction

Malfunction of the heater (heater) or defrost timer. Different models have one or two heating elements (evaporator and defrost); if even one device breaks down, the refrigerator does not work. The reason for the breakdown of the heating element may be an increase in frost on the evaporator, which will require replacement of the part;

Start relay failure

A breakdown of the starting relay occurs when the moving contacts jam, the elasticity in the moving plate decreases, or the heating coil burns out. In these cases, the light is on, the refrigerator does not freeze or starts for a short time. To eliminate the malfunction, diagnostics, further repairs, and replacement of the part are carried out only by specialists who inspect the contacts, ring the coils, and disassemble the relay;

Filter drier failure

This device must be replaced if it is clogged, accumulated moisture, unqualified repairs or wear.

Review of Liebherr refrigerator faults

Malfunctions of the device may be due to improper operation and defects. Among the main malfunctions that arise are:

• Damage to wires causing electric shocks.
• Broken fittings . A common situation if the period of use exceeds 6 years. Drawers break down, handles break and fasteners fly out.
• Spontaneous shutdown of the device . The simplest and most common reason is a loose plug.
• Lack of cold can occur for a number of reasons: from wear of the seal to freon leakage. A malfunction can be caused by a failed cooler, compressor, temperature sensor, or fan.
• Broken backlight . May occur due to a stuck power button. Another situation is a lamp that requires replacement with a new one.
• The appearance of water , and liquid can collect inside the device or outside. The situation may arise due to damage to the pan, lack of electricity, or clogged drainage system. Puddles may appear if there is food near the evaporator.
• A sharp drop in temperature in the freezer , the appearance of frost in the refrigerator compartment. A common cause is a breakdown of the temperature sensor, but trouble can also be caused by an incorrect freezing program erroneously set by the user. Another explanation is a failed cooling system.
• The door does not close tightly . May occur due to wear of the seal, overload of shelves. The problem is caused by a deformed door or a broken spacer.
• Noisy operation of the refrigerator . A common cause is loose fasteners or frozen blades. However, the problem may arise due to the strong tilt of the refrigerator.
