Switching off the refrigerator for a long time is a situation that is encountered when moving, repairing or seasonally using country equipment. But simply unplugging the plug from the socket is not enough: improper preservation leads to mold, corrosion of metal parts, and even breakdown of the compressor when turned on again. In this article we will look at step-by-step preparation algorithm, the nuances of storage depending on the model (No Frost, drip system, Low Frost) and typical mistakes that shorten the service life of equipment.
Special attention Let's pay attention critical parameters of humidity and temperature inside the chamber —they are the ones who determine whether odor or fungus will appear after 2-3 months of inactivity. You will also learn how to protect the sealing gum from cracking and what to do with refrigerators that cannot be placed vertically (for example, Samsung RB37J5240SA or Liebherr CNef 4315 with a system BioFresh).
1. Preparing the refrigerator for shutdown: step by step step
The first stage is complete defrosting and cleaning. Even if your Indesit or Atlant supports the function No Frost, if left unused for a long time, ice and condensation will become a source of bacteria. Start by disconnecting from the power supply and leaving the door open. 12–24 hours - this will speed up the melting of the ice in the freezer.
For cleaning, use specialized products (for example, Topperr 3104 or Sano Refrigerator Cleaner), avoiding abrasive powders and bleach - they damage the antibacterial coating pay special attention to:
- 🧊 Drainage hole (in models Beko and Gorenje it is often clogged with food debris).
- 🧽 Sealing rubber —wipe it with a solution of vinegar (1:1 with water) for disinfection.
- ❄️ Evaporator (in systems
No Frost) - dust on it worsens heat transfer when turned on again.
☑️ Checklist before disconnecting
After cleaning, dry the chambers with a towel or hairdryer (at minimum power, holding at a distance of 30 cm). The humidity inside should drop below 50% - check. a hygrometer or special humidity indicators (for example, Xiaomi Mijia TH1).
2. How to store correctly: vertically or horizontally?
The position of the refrigerator during storage depends on compressor type and the manufacturer's recommendations. Most modern models (LG GA-B489YDQZ, Bosch KGE39XW2AR) can only be stored in a vertical position. The exception is equipment with linear inverter compressors (for example, Hitachi R-VG460PUC6), which can be laid on its side, but not more than that. at 45°.
If you have to transport or store the refrigerator lying down, follow the rules:
- 🚫 Prohibited put it on the back wall - this damages the condenser and tubes.
- ⏳ Maximum period in a horizontal position - 24 hours (for models with a conventional compressor).
- 🔄 After storage before turning on, wait 6-12 hours in a vertical position (the oil must drain into the compressor).
| Refrigerator model | Permissible storage position | Maximum tilt angle | Holding time before switching on |
|---|---|---|---|
| Samsung RB37J5240SA | Only vertical | 0° | 4 hours |
| Liebherr CNef 4315 | Vertical or at an angle up to 30° | 30° | 8 hours |
| Atlant MHM 1705-80 | Vertical | 0° | 12 hours |
| Hitachi R-VG460PUC6 | Horizontally (on the side) | 90° | 24 hours |
⚠️ Attention: If the refrigerator was stored lying down for more than a day, before turning on, check the oil level in the compressor through the inspection window (if it is provided for in the design, if there is a lack of oil, contact the service center). service.
3. Protection from mold and unpleasant odors
The main enemies of a switched-off refrigerator are mold and musty smell. They appear due to residual moisture and organic particles on the walls. To prevent them:
- Use odor absorbers. Suitable:
- 🧂 Soda (2-3 open packs on the shelves).
- ☕ Activated carbon (10-15 tablets in a fabric bag bag).
- 🍋 Citrus zest (dried in oven at 100°C).
For models with the system No Frost (Electrolux ENN2853AOW, Whirlpool ART 9810, additional protection is not required - their design prevents the formation of condensation. But if the refrigerator is stored in a damp room (basement, garage), it is recommended to ventilate it once a month by opening the door for 30–60 minutes.
What to do if mold has already appeared?
If black spots appear on the walls or seal, wipe them with a solution of vinegar (1:1) or a special product Cillit Bang Black mold> After treatment, dry the surfaces with a hairdryer and repeat the procedure after 2-3 days. In advanced cases, it may occur. it will be necessary to replace the sealing rubber (cost for models Samsung —from 1500 ₽, for Liebherr —from 3000 ₽).
⚠️ Attention: Do not use aromatic air fresheners (for example, Air Wick) - their chemical composition may react with the plastic of the internal panels and cause yellowing.
4. Features of preservation of refrigerators with different defrosting systems
Defrosting technology affects preparation for storage:
1. Drip system (Defrost) (Indesit DF 4180 W, Beko CNK 335120):
- 💧 Requires mandatory manual defrosting —ice in the drainage system when melting can flood the lower compartments.
- 🔧 After defrosting, check drain hole (often clogged in models older than 5 years).
2. No Frost (Full No Frost, Total No Frost) (Samsung RB-30 J3200EF, LG GA-B429SLGL):
- ❄️ Defrosts automatically, but before storage still needs cleaning —dust on the evaporator impairs performance after switching on.
- 🌬️ It is recommended to leave the door ajar 5-10 cm for ventilation.
3. Low Frost (Liebherr CTPesf 3555, Gorenje RK 6292 AW):
- ⚙️ Combined system: the freezer is defrosted manually, and the refrigerator compartment is defrosted automatically before storage. defrost both zones.
- ⏱️ Defrosting time can reach 24 hours due to the thick layer of insulation.
For models with freshness zone (BioFresh, FreshZone) additionally remove all removable containers and dry them separately. Wet plastic parts become deformed during long-term storage.
5. Typical mistakes and their consequences
Even minor miscalculations during conservation lead to serious problems. Here are the most common:
1. Storage with the door closed. Without air circulation, moisture condenses on the walls, which leads to:
- 🍄 The appearance of mold within 2-3 weeks.
- 🤢 A persistent odor that does not go away even after washing.
- 🔧 Corrosion of metal parts (in models with an open condenser, for example, Stinol STN 167).
2. Using plastic film for covering. It creates a greenhouse effect and accelerates the development of bacteria. Instead, use breathable non-woven covers. material (sold in household goods stores).
3. Storage in an unheated room at a temperature below 0°C. This leads to:
- 🧊 Freezing of condensate in the drainage system.
- 🔋 Discharge of the starting capacitor (in models with electromechanical control).
- 🛠️ Cracks in plastic parts (due to temperature shock).
6. Preparing to turn it on again
Before using the refrigerator again, take several mandatory steps:
- Inspect the rubber seal. If it has lost its elasticity or becomes cracked, replace it (cost for Atlant —from 800 ₽, for Bosch —from 1200 ₽).
- Check the drainage hole. Pour 50–100 ml of water into it - the liquid should flow freely into the pan.
- Make sure there are no foreign odors. If there are any, rinse the chambers with a soda solution (2 tablespoons per 1 liter of water) and dry.
- Connect to the network and let it run. stand for 2-3 hours before loading the products. This is necessary to stabilize the temperature.
For models with electronic control (Samsung RL-44 QEBS, LG GB-B459SLQZ), after turning on, reset the settings to factory settings (Settings → General → ResetThis will eliminate possible errors caused by long periods of inactivity.
⚠️ Attention: If the refrigerator was stored in a horizontal position, after installing it in a vertical position, check the oil level in the compressor through the inspection window (if there is one). If there is a lack of oil (visible by the marks MIN/MAX), do not turn on the equipment - contact service.
7. Frequently asked questions about storing a switched-off refrigerator
Is it possible to store a refrigerator on the balcony in winter?
No, if the temperature drops below +5°C. Plastic parts become fragile, and electronic components (in models with a display) may fail. (Nord, Pozis), designed to operate at -15°C.
How often do you need to ventilate the refrigerator during storage?
In a dry room - once every 1-2 months (it is enough to open the door for 30 minutes). In a damp room (basement, garage) - once every 2 weeks. Use a hygrometer to control humidity: it should not. exceed 60%.
What to do if after turning on the refrigerator does not cool?
Probable reasons:
- 🔌 Problems with the compressor (if the equipment was stored lying down).
- ❄️ Clogged capillary tube (due to corrosion at high humidity).
- 📉 Freon leak (if the seal was damaged).
Do not try to repair it yourself - contact your service center.
Is it necessary to lubricate the sealing rubber before storage?
Yes, this will prevent cracking. Use silicone grease (for example, WD-40 Specialist) or apply a thin layer of glycerin to a clean surface. dry surface once every 3 months.
Is it possible to store a refrigerator without packaging?
It is possible, but only in a dry, clean room. If the equipment is in a garage or basement, cover it breathable cover (not polyethylene!) or sheets made of natural fabric. This will protect from dust and mechanical damage.
