Modern refrigeration units Liebherr are famous for their energy efficiency and complex electronics that require careful handling. Often a situation arises when it is necessary to turn off the device: for a long trip, general cleaning, or when moving to a new place of residence. Simply unplugging the cord from the socket in most cases is not enough, since odors may remain inside, and the compressor requires time to stabilize before restarting.
The correct sequence of actions will help avoid system breakdowns NoFrost and the appearance of mold during downtime. Owners often forget that electronics must “sleep” correctly, and moisture must completely evaporate. If you ignore these nuances, the equipment may fail the next time you turn it on or require expensive disinfection.
In this article we will analyze all the stages of preparing the device for downtime, starting with software settings and ending with preservation of the unit. You will learn why rushing can damage the mechanism and how to keep the internal chambers fresh even when the power is turned off.
Preparing for shutdown and cleaning the chambers
The first step before any maintenance or long-term downtime is to clear the internal space of food. Even if you plan to turn off the unit for just a couple of hours for cleaning, the presence of perishable goods is unacceptable. Completely remove all shelves, drawers and containers to provide access to the walls and corners of the chambers.
After emptying the contents, you must carry out a thorough defrosting if your model does not support automatic defrosting of the evaporator. In models with a system defrosting (defrost) if your model does not support automatic evaporator defrost. In models with the system Liebherr SmartFrost or full NoFrost the ice crust grows slowly, but for perfect cleanliness it is better to wait for complete melting. Open the doors and leave the device for several hours, laying towels on the floor to collect condensation.
⚠️ Attention: Do not use sharp objects, hair dryers or hot water to accelerate the melting of ice, as this may damage the thin evaporator tubes or deform the plastic elements of the internal lining.
When the ice melts, wash all surfaces with a weak solution of soda or a specialized product for refrigerators. Pay special attention to the rubber seals on the doors, where dirt and bacteria most often accumulate. Cleanliness inside is the key to the absence of an unpleasant musty smell after you decide to turn on the device again.
☑️ Checklist for preparing for shutdown
Program shutdown via the control panel
Many modern models Liebherr equipped with digital display and electronic control, which requires the correct shutdown algorithm. Simply turning off the power in this case means stressing the controller. First, you need to activate the shutdown mode directly through the device interface.
On most control panels, this requires pressing and holding the on/off button (usually indicated by the power symbol) for 3-5 seconds. A flashing indicator or a symbol of a crossed out fan may appear on the screen, which signals the transition to standby mode. In some models of the series Comfort or Premium you need to sequentially press the key combination specified in the instructions.
After activating the software shutdown, the compressor and fans will stop working, but the electronics can remain powered for some time to complete internal processes. This is important for correctly saving settings and system state. Only after all the indicators on the display have gone out can you proceed to physically disconnecting from the network.
What to do if the panel does not respond?
If pressing the buttons does not produce results, the Child Lock may be activated. To remove it, you usually need to hold the button with the image of a lock or a combination of keys for 4-6 seconds until the corresponding sound signal appears or the indication on the screen changes.
Do not rush to pull out the cord until the device gives a clear signal that it is ready to turn off the power.
Physical disconnection from the power supply
When the program cycle is completed, the stage of physically breaking the circuit begins. To do this, carefully pull the plug out of the socket. If access to the outlet is difficult due to tight installation of equipment against the wall, act carefully so as not to damage the cable or move a heavy unit suddenly.
In cases where the outlet is located in a hard-to-reach place, many users ask the question: is it possible to use an extension cord or surge protector? For refrigerators Liebherr the manufacturer recommends direct connection. However, if you plan to turn off the device during the holidays, using a high-quality surge protector with protection against power surges will be a reasonable solution when turning it back on.
| Action | Description of the process | Importance |
|---|---|---|
| Program stop | Stopping the compressor through the menu | High |
| Removing the plug | Only by the plastic part, not by the wire | Required |
| Waiting | Pause 5-10 minutes before restarting | Critical |
| Check the cable | Inspect for damage when disconnecting | Recommended |
If you disconnect refrigerator for transportation, secure the doors with tape or special transport tape so that they do not open spontaneously during travel. Also make sure that the power cord is not pinched or has any creases after manipulating the equipment.
Rules for storing a switched-off refrigerator
The biggest mistake when storing a switched-off unit for a long time is to leave it hermetically sealed. Inside a confined space without air circulation, mold and bacteria immediately begin to develop, especially if even the slightest moisture remains. This will lead to the appearance of a persistent unpleasant odor, which is then very difficult to get rid of.
The doors of the refrigerator and freezer compartments should remain ajar during the entire period of inactivity. Use special clamps if they are included, or simply insert a rolled towel or cardboard spacer between the body and the seal. This will ensure a constant flow of fresh air and evaporation of residual moisture.
⚠️ Attention: If there are small children or pets in the house, make sure that the ajar door is securely fixed and the child cannot slam it inside, getting stuck there.
The storage place should be dry and protected from direct sunlight. Ultraviolet radiation can cause plastic to fade and rubber seals to yellow. The optimal storage temperature is room temperature, avoid unheated garages or balconies in winter if the temperature there drops below +5°C, as this can negatively affect the lubrication of the compressor and the condition of the rubber.
Nuances of turning off models with an ice maker
Owners of refrigerators Liebherr with a built-in ice maker or system Liebherr IceMaker should take into account additional steps. Water remaining in pipes and reservoirs can rupture lines when frozen, and can bloom if left idle for a long time. Therefore, before completely cutting off the power, it is necessary to drain the water from the system.
The procedure usually begins by turning off the water supply tap, which is located on the pipeline behind or next to the refrigerator. After turning off the water, you need to run the ice making cycle several times (if there is power) or simply wait until the water drains by gravity into the drain, if the design allows it. Some models require you to remove the ice maker module itself and dry it separately.
Be sure to blow out the water supply pipes or leave them open so that the moisture completely evaporates. Stagnant water in narrow channels is an ideal breeding ground for legionella and other microorganisms. After drying, reassemble the system, but do not connect the water supply until you turn it on again and check for leaks.
Starting up after a long period of inactivity
When the time comes to use the refrigerator again, do not rush to load it with food. After long-term storage, the device requires time to adapt. Plug in the appliance, but leave the doors closed. Let the compressor run idle for 2-4 hours so that it reaches operating temperature conditions.
During this time, check the operation of all indicators and listen to the sound of the motor. It should be smooth, without extraneous knocking or whistling. If everything went well, you can gradually load the products, starting with those that require a less strict temperature regime.
On the first day after switching on, watch for the formation of condensation on the outer walls - there should not be any. Also check the tightness of the doors, since during idle time the seals may have become slightly deformed or covered with dust.
Frequently asked questions (FAQ)
Is it possible to turn off a Liebherr refrigerator at night to save energy?
It is strictly not recommended to do this regularly. Frequent on and off cycles lead to rapid wear of the compressor and start relay. In addition, food may spoil due to temperature violations. Modern models already consume little energy.
How long should you wait before turning it on again after a shutdown?
If you just unplugged the device from the outlet, it is recommended to wait 5-10 minutes before turning it on again. This is necessary to equalize the refrigerant pressure in the system. If the refrigerator has been turned off for a long time, 10-15 minutes of acclimatization at room temperature is enough.
What to do if the refrigerator does not freeze after turning it on?
First, check whether the doors are tightly closed and whether the power indicator is on. Let the device run for 3-4 hours without booting. If the cold does not appear, check if the power cord is pinched and if there is voltage at the outlet. If the problem persists, diagnostics from a service center will be required.
Do you need to lubricate the seals before long-term storage?
Yes, this is an excellent practice. Wipe the rubber seals with glycerin or special silicone grease. This will prevent the rubber from drying out, cracking and maintain the elasticity of the cuffs during downtime.
