Refrigeration equipment Liebherr
is famous for its durability and complex control system, which makes the procedure for turning it off not as trivial an action as it might seem at first glance. Owners often wonder how to do this correctly so as not to damage the compressor or electronics system when moving or prolonged downtime.Incorrect shutdown of the unit can lead to a refrigerant leak, damaged tubes, or failure of the control board. In this material we will analyze in detail all the stages: from setting up the idle mode to completely dismantling the device.
Preparing for shutdown: assessing the situation
Before taking active steps, you need to clearly define the purpose of your manipulations. If you just need to defrost the unit, the algorithm will differ from the situation when it is required complete conservation of equipment for transportation.
In the case of planned defrosting, it is enough to turn off the power, but it is important to wait until the system completely stops. If you plan to move, then it is critically important to empty the chamber of food and give the device time to adapt the temperature.
It is worth considering that modern models Liebherr are equipped with intelligent systems that may require completion of operating cycles through the program menu. Ignoring this step may lead to errors in the logic of the controller the next time it is turned on.
⚠️ Attention: If the model is equipped with the NoFrost system, forced shutdown without stopping the fans can lead to the accumulation of condensation in hard-to-reach places, which can lead to the formation of ice inside the case.
Shutdown via the control panel
Modern digital control panels require the correct shutdown of software processes. Simply unplugging the cord from the socket can be perceived by the controller as an emergency.
To complete the work correctly on many models, you must press the power button and hold it for 3-5 seconds. The operation indicator should go off on the screen, and a sound signal will confirm the transition to standby mode.
- 🔌 Find the power button on the display or a separate key
Power. - 👆 Hold down until the sound signal or indicator flashes.
- 📉 Wait until the display backlight goes out and the compressor will shut down.
If your model has touch controls, make sure your hands are dry to avoid false alarms. Some series Liebherr require sequential pressing of a key combination to enter the service shutdown mode.
After the software shutdown, the system may still make quiet sounds for some time - this is normal, as the pressure in the refrigerant circuits is being released. Do not rush to immediately turn off the device from the network.
Disconnecting the power supply and checking the wiring
Physically disconnecting from the electrical network is the next important step. Refrigerators Liebherr are characterized by the use of high-quality, but specific connectors that require careful handling.
Always grasp the plug itself, and not the wire. A sharp tug can damage the internal contacts or loosen the cable in the case, which will lead to sparking the next time you turn it on.
Check the condition of the socket and plug. If you notice traces of soot, melting or smell a burning smell, operating the equipment in its current form is strictly prohibited.
☑️ Safe power off
⚠️ Attention: In older models or when using extension cords, the contact of the plug with the socket may be loose. When removing, a spark may occur - this is normal, but requires a visual check of the contacts.
If the refrigerator is built into a kitchen unit, access to the outlet may be difficult. In such cases, they often use a circuit breaker on the panel, but it is better to find a way to turn off this particular line so as not to de-energize the entire kitchen.
Procedure for defrosting and removing moisture
After turning off the power, the defrosting process begins. For models with manual defrosting or drip system, this is a mandatory step before transportation.
Open all doors and remove food. Leave the unit open for at least 12-24 hours to allow the ice to completely melt. Speed up the process with a hairdryer or hot water not recommendedas a sharp temperature change is dangerous for the plastic and evaporator tubes.
| System type | Defrosting time | Do I need to open doors | Risk of damage |
|---|---|---|---|
| NoFrost | 4-6 hours | Desirable | Low |
| Drip | 12-18 hours | Required | Medium |
| Manual | 24 hours+ | Required | High (in a hurry) |
| DuoCooling | 12-24 hours | Required | Average |
Prepare containers for collecting water and rags. Water may leak from the drainage hole located on the back wall inside the chamber. It needs to be cleaned with a brush if there is a blockage there.
What to do with the water in the compressor sump?
In some models, water flows into the sump above the compressor. It evaporates naturally during operation. When disconnecting, this water must be removed with a syringe or sponge to avoid corrosion and odor.
Dismantling and preparation for transportation
If the purpose of disconnecting is moving, then after defrosting the stage of preparation for transportation follows. Refrigerators Liebherr have heavy doors and fragile fastening elements.
Be sure to secure the doors with tape or special transport tape. This will prevent them from swinging open during movement, which could lead to hinges coming off or damage to the seal.
- 🚚 Remove all shelves and drawers - they must be transported separately.
- 🔧 Fix the moving elements inside the chamber (if any).
- 🧼 Wipe the internal surfaces with a dry cloth.
- 🔒 Secure the doors with masking tape in the closed position.
When transporting, it is important to maintain the angle of inclination. For compressors Liebherr the permissible tilt angle usually does not exceed 40 degrees, but it is better to clarify this in the instructions for the specific model.
⚠️ Attention: After transportation, the refrigerator must stand in a vertical position for at least 4 hours (preferably 8-10) before turning it on. This is necessary so that the oil flows into the compressor.
Common mistakes when turning off equipment
Many users make mistakes that shorten the life of expensive equipment. One of the most common is an attempt to immediately turn on the refrigerator after transportation.
Another mistake is the use of aggressive chemicals for cleaning before turning it off. Chemical residues can corrode plastic or rubber seals while the appliance is standing without ventilation.
Also, do not leave the refrigerator unplugged with the doors closed. This is guaranteed to lead to the appearance of mold and an unpleasant odor, which is then very difficult to remove.
Possible problems after switching on
After a long period of inactivity or transportation, nuances may arise when switching on for the first time. The compressor may operate louder than usual for the first 20-30 minutes - this is the process of reaching the operating mode.
If the alarm icon lights up on the display or the temperature indicator flashes, do not panic. Give the unit time (up to 24 hours) to reach operating temperature. The system Liebherr calibrates itself.
In rare cases, it may be necessary to reset the settings to factory settings if the electronics “remembered” erroneous parameters. This is done through the settings menu, the combination of buttons depends on the series.
Do you need to lubricate the hinges before turning it off?
Lubricating the hinges with special compounds before long periods of inactivity is not recommended if you do not plan to use the refrigerator for several years. Dust may adhere to the lubricant. You just need to wipe them with a dry cloth.
Is it possible to turn off the refrigerator in hot weather?
Yes, but after turning it on, it will take more time and energy to cool the chambers. It is better to do this in the evening or when the room temperature is lower.
What to do if the light does not come on after turning it on?
Check whether the doors are tightly closed. In modern models, the light often goes out if the sensor considers the door open for too long, or, conversely, does not turn on if it is not closed tightly. Also check if the "Vacation" or demo mode is activated.
How long can you keep the refrigerator turned off?
Without negative consequences for the equipment - as long as you like, provided that it is dry, clean and the doors are slightly open. Rubber seals may lose elasticity over time, but this is a process of natural aging, and not a consequence of downtime.
