Long absence from home, moving or seasonal use of a summer house often poses a difficult question to owners of household appliances: what to do with the refrigerator? Many people mistakenly believe that it is enough to simply unplug the cord from the socket and slam the door, but this approach can lead to serious consequences, including the failure of an expensive compressor or the appearance of intractable mold.
Improper preservation of equipment can turn a reliable unit into a breeding ground for bacteria and an unpleasant odor, which is almost impossible to get rid of even after turning it back on. In this article, we will analyze in detail all stages of preparation, explain the physical processes occurring inside the system during idle time, and give clear recommendations for storing equipment in various conditions.
Why you can’t just unplug the cord from the socket
The refrigerator is a complex sealed system, inside which refrigerant and special fluid circulates. data-i="50">. In operating condition, the oil is located at the bottom of the compressor, but during operation it is partially mixed with the refrigerant and circulates through the circuit. If you abruptly turn off the power, the oil does not have time to drain back into the crankcase, remaining in the tubes and heat exchangers. compressor oil. In operating condition, the oil is located at the bottom of the compressor, but during operation it is partially mixed with the refrigerant and circulates through the circuit. If you suddenly turn off the power, the oil does not have time to drain back into the crankcase, remaining in the tubes and heat exchangers.
Switching on the unit immediately after shutdown, when the oil has not yet settled, can lead to water hammer or operation of the compressor without proper lubrication, which sharply reduces its life. That is why manufacturers categorically do not recommend turning on the device earlier than a few hours after disconnecting from the network.
⚠️ Attention: In modern models with inverter compressors LG or Samsung electronics can block the start until the pressure in the system stabilizes, but you still should not risk the mechanical part costs.
In addition, a sudden stop in operation disrupts the temperature balance. Condensation remains inside the chambers, which, when quickly cooled or, conversely, heated, can turn into an ice crust or become a breeding ground for microorganisms. The correct sequence of actions allows you to avoid these problems and keep the equipment in perfect condition.
Stages of preparing the refrigerator for long-term downtime
Before leaving the equipment unattended, it is necessary to carry out thorough preparation. This process does not take much time, but guarantees the safety of internal surfaces and mechanical components. The first step is to completely empty the chambers of food, defrost the evaporator and carry out high-quality cleaning.
Particular attention should be paid to removing moisture. Even microscopic drops of water in hard-to-reach places can cause mold to appear during downtime. After washing, all surfaces should be absolutely dry, and the doors should be open for ventilation.
☑️ Checklist for preparing for preservation
Do not forget to check the condition of the sealing rubber bands. If food or moisture remains on them, the rubber may darken, lose elasticity, or develop a black coating. To care for the seals, you can use special products or regular glycerin, which will prevent the material from drying out.
How to properly wash and dry the internal chambers
Hygienic treatment is a critically important step. Use only mild detergents that do not contain aggressive abrasives or chlorine, which can damage the plastic. Baking soda solutions or special sprays for household appliances have proven themselves to be effective.
After wet cleaning, be sure to wipe all surfaces with a dry rag or paper towels. Pay special attention to corners, panel joints and drainage holes where water most often accumulates. If you leave moisture in the drainage, fungus can develop inside the cabinet, the smell from which will be very difficult to eliminate.
To completely dry, leave the refrigerator open for at least 24 hours. A draft will help evaporate residual moisture from the pores of plastic and insulating materials. Some models Bosch or Liebherr have a complex system of air ducts that also need to dry out.
Where and how to store a switched off refrigerator
The choice of storage space plays a decisive role. The ideal option is a heated room with moderate humidity. Sudden temperature changes and high humidity can negatively affect metal and plastic parts, causing corrosion or deformation.
If you plan to store equipment on a balcony or in a garage, make sure that the temperature does not fall below the permissible values specified in the instructions (usually not lower than +5°C, although modern refrigerants can withstand extreme cold, but the oil thickens). Direct sunlight is also dangerous: they lead to burnout of plastic and destruction of seals.
| Storage conditions | Effect on equipment | Recommendation |
|---|---|---|
| High humidity | Corrosion metal, mold | Use dehumidifiers |
| Direct sunlight | Destruction of plastic, fading | Cover with light-proof fabric |
| Dusty room | Clogging of ventilation grilles | Close the case tightly with a cover |
| Low temperature | Oil thickening, plastic cracks | Do not store at temperatures below +5°C |
Do not tightly pack it with boxes or push it close to the wall on all sides, unless it is a special case for transportation.
Protection from dust, rodents and external influences
Dust is the main enemy of electronics and heat exchangers. As it settles on the condenser (the black grille at the back), it impairs heat transfer and can cause overheating when turned on for the first time. In addition, dust penetrates inside through the ventilation holes, settling on the evaporator and fans.
Rodents pose an equally serious threat. Mice and rats often choose warm places behind insulation or inside chambers to create nests, chewing wires and damaging the insulation. To prevent this, use thick fabric covers or special protective films.
⚠️ Attention: Never use plastic film for cover, wrapping it tightly around the body. This creates a greenhouse effect, leading to condensation and rust on metal surfaces.
Breathable fabric covers or an old sheet are best for protecting against dust. If the refrigerator is stored in a garage or shed, make sure that there are no open foods in the room that could attract animals.
Does it need to be transported lying down
Often the question of turning it off arises when transportation is necessary. There are strict rules here. It is recommended to transport the refrigerator strictly in an upright position. This is due to the fact that when tilted more than 40 degrees, oil from the compressor can flow into the refrigerant circuit.
If transportation in a vertical position is impossible (for example, not included in an elevator), the unit can only be laid on its side, and then with great restrictions. It is strictly forbidden to place the refrigerator on the back (where the condenser is located) or on the door.
Which side can you place the refrigerator on?
Usually, manufacturers recommend placing the equipment on the side opposite the side where the tubes exit the compressor. Look at the back wall: if the tubes come out from the left, you need to place them on the right side, and vice versa. This minimizes the risk of oil leakage.
After any transportation in a horizontal position, the refrigerator must stand in a vertical position before turning on. The settling time depends on the duration and angle of inclination during transportation, but usually ranges from 4 to 24 hours. This time is necessary for the oil to completely drain into the compressor crankcase.
Correct starting after a long period of inactivity
When it’s time to use the refrigerator again, do not rush to load it with food. After long-term storage, especially in an unheated room, equipment needs acclimatization. Bring the unit into a warm room and let it warm up to room temperature to avoid condensation on the electronic boards.
Plug in the empty refrigerator and leave it running for 2-3 hours. During this time, the system will return to operating mode, the pressure will stabilize, and the compressor will return to normal temperature conditions. Only after the refrigerator has gotten cold can you add food.
When you turn it on for the first time, listen carefully to the operation of the motor. Extraneous knocking, hum or lack of cooling may indicate problems that arose during the period of inactivity, for example, solidification of the oil or damage to the seals.
Typical mistakes when preserving equipment
Many users make mistakes that nullify all efforts to preserve equipment. One of the most common is closing the door tightly. This leads to mustiness, mold and deformation of seals due to lack of air circulation.
Another mistake is the use of aggressive chemicals for washing. Residues of acids or alkalis can corrode plastic and metal, especially in conditions of high humidity during idle time. Also, do not leave forgotten food or containers with liquid inside.
Ignoring the manufacturer's instructions is another risk. Different models may have their own characteristics. For example, in some systems No Frost moisture may be retained in hidden channels, requiring more thorough drying with a hair dryer (in cold air) or prolonged ventilation.
What will happen if you do not dry the refrigerator before turning it off?
The remaining moisture will become an ideal environment for the growth of bacteria and mold. After a few weeks, a persistent unpleasant odor will appear inside, which is very difficult to remove. Mold can affect not only plastic panels, but also penetrate into the insulation, which will require serious repairs.
Is it possible to turn off the refrigerator at night?
Turning off the refrigerator at night in order to save energy does not make sense and is even harmful. Food can begin to spoil within 8 hours, and frequent cooling and heating cycles place additional stress on the compressor when starting up in the morning. Modern models of energy efficiency class A+ and higher consume a minimum of energy.
How long can a refrigerator be stored when turned off?
Under the right storage conditions (dry, warm room, open doors), the refrigerator can remain turned off for years without damage to the mechanics. However, rubber seals lose elasticity over time even without load, so it is recommended to lubricate them with glycerin every six months.
Do you need to secure the doors with tape during storage?
Yes, if there is a risk that the door will slam shut (for example, from a draft or vibration). However, you cannot use ordinary stationery tape - it will leave traces of glue. Use masking tape or simply insert a wedge (for example, a rolled up towel) between the body and the seal to leave a gap of 1-2 cm.
