Modern refrigerators with the system No Frost (without frost) significantly simplify life by relieving owners of the need for regular manual defrosting.
However, situations arise when the equipment needs to be completely turned off: a long vacation, moving, general cleaning or scheduled maintenance.
Unlike old models with a crying evaporator, there are some nuances associated with air circulation and electronics.
Completing the procedure correctly will help avoid the appearance of unpleasant odors, mold and will extend the life of the compressor.
Power shutdown sequence
The first step is always to cut off the power supply. This seems obvious, but it is important to follow the procedure for the safety of electrical circuit refrigerator.
Do not pull on the cord to disconnect it from the outlet - this may damage the contacts or the cable itself. Grasp the plug and smoothly remove it.
If the socket is located in a hard-to-reach place (for example, behind a cabinet), it is better to provide an extension cord or access to the machine on the panel in advance.
After removing the plug, make sure that all indicators on the control panel go off.
Many modern models are equipped with an electronic control, which can save settings in memory.
Turning off the power resets current settings temperatures, but does not erase factory settings.
For models with a display, it is important to let the electronics completely de-energize, which takes a few seconds after unplugging cord.
⚠️ Attention: If you plan to turn off the refrigerator for a long period of time (more than a month), it is recommended to turn it on for a few hours once every 3-4 months. This is necessary so that compressor oil does not thicken and harden in the tubes, and also so that the lubricant is distributed throughout the system.
You should not ignore this advice, since starting a “dry” compressor after a long period of inactivity can lead to to its jamming.
Complete defrosting of the No Frost system
Although the system is called “no frost,” the moisture in the air still condenses and freezes on the hidden evaporator.
With a long shutdown, this ice should melt naturally. Speeding up the process with a hairdryer or hot water is strictly prohibited.
Temperature changes can cause microcracks in plastic parts and evaporator tubes, which will lead to leakage refrigerant.
Leave the doors open for at least 24 hours for the internal channels to completely dry.
The water will flow into a special pan located above the compressor at the back.
Do not forget to periodically check and empty it so that the water does not overflow onto the floor.
To speed up the evaporation of moisture, you can wipe the internal surfaces with a dry rag, but without using chemistry.
☑️ Preparation for defrosting
It is better to remove the glass shelves separately and wash them at room temperature to avoid thermal shock.
Cleaning and disinfection before preservation
The downtime period is the ideal time for general cleaning. Leftover food or juices can become a source of bacteria.
Use a weak solution of soda or special detergents for washing household appliances.
Carefully wipe all corners, door seals and vents.
Pay special attention to the area around magnetic tape of the seal - dirt most often accumulates there.
| Cleaning zone | Meanium | Tool | Frequency |
|---|---|---|---|
| Internal walls | Soda solution (1 tbsp per liter) | Soft sponge | When disconnected |
| Door seals | Warm water | Cotton stick | Monthly |
| Shelves and drawers | Glass cleaner | Microfiber cloth | As it gets dirty |
| Ventilation holes | Dry brush | Long bristled brush | Once a year |
After wet cleaning, be sure to wipe the surfaces dry.
The remaining moisture in a closed space will create ideal conditions for the development of mold.
Storage rules in the off state
The most important rule for preserving a refrigerator is that it must be stored with the doors open.
If you close an empty refrigerator, mold will instantly begin to develop inside and a musty smell will appear, which is then very difficult to remove.
The gap should be sufficient for air circulation, but not so large that it can a cat or a child can climb in.
You can use special clamps or simply place a rolled up towel between the door and the body.
⚠️ Attention: Do not store the refrigerator in an unheated room (garage, balcony) in winter if the temperature drops below +5°C. This can lead to cracking of the plastic and damage sealing rubber bands due to loss of elasticity.
It is also important to protect equipment from direct sunlight, which causes yellowing plastic.
If the refrigerator is in the kitchen, cover it on top with a breathable fabric so that dust does not accumulate, but there is air access.
Nuances for models with an ice maker
Owners of American refrigerators with the system Ice Maker need to perform additional action.
Be sure to turn off the water supply before disconnecting the device from the network.
Drain all remaining water from the system so that when it freezes it does not break the thin tubes.
Remove the ice tray and rinse it separately.
In some models have a function sanitary treatmentthat should be launched before the final shutdown.
Check the instructions for your model Samsung or LG for specific winter requirements storage.
What to do with the water filter?
If a cartridge water filter is installed in the refrigerator, it is better to remove it and store it separately in the refrigerator (not in the freezer!) or throw it away if its service life is coming to an end. In a dry state, the filter membrane may degrade.
How to properly turn on the refrigerator after inactivity
When the time comes to start the appliance again, do not rush to load the products.
First, wipe the internal surfaces again to remove settled dust.
Turn on connect the refrigerator to the mains and let it run empty for 2-4 hours.
This time is necessary to stabilize temperature conditions and check the tightness of the system.
Only after the refrigerator gets cold, you can gradually load products.
Do not put a lot of warm products at once - this will put extra load on the compressor.
Following these simple rules will ensure that the equipment will serve you for many years without breakdowns or unpleasant surprises.
Frequently asked questions (FAQ)
Is it possible to transport the No Frost refrigerator lying down?
It is highly not recommended. When transporting lying down, there is a risk of displacement compressor oil into the cooling circuit or damage to the tubes. If there is no other way out, transport only on the side opposite the exit of the tubes from the compressor, and after installation, let it stand vertically for at least 24 hours before turning it on.
Do you need to lubricate door seals before long-term storage?
Yes, this is useful procedure. Wipe the rubber seal with glycerin or special silicone grease. This will prevent the rubber from drying out and cracks from appearing, preserving the chambers. tightness cameras.
Why does the refrigerator buzz loudly after turning on?
If the buzzer appears after a long period of inactivity, this may be a sign that the compressor “sour” or air remains in the system. Also check whether the refrigerator is level - the legs should be adjusted to the level. If the noise does not subside after an hour of operation, contact the service.
Is it dangerous to leave the refrigerator turned off in the winter at the dacha?
Yes, if the room is not heated. In addition to the risks to plastic and rubber described above, condensation inside electronics can cause a short circuit when first turned on. It is better to take the equipment to a warm place or ensure a positive temperature in the room.
