Leaving for the dacha, moving or simply being away from home for a long time poses a difficult question for the owner of household appliances: what to do with the refrigerator? Leave it running or turn it off? If in the first case everything is relatively clear, then in the second there is a risk of an unpleasant odor or even failure of the compressor if it is not properly preserved.
There are many myths that equipment should “rest” with the power on, or that the door should be sealed with tape. The reality is that prolonged downtime requires strict adherence to the algorithm of actions. Ignoring the basic rules of preparation can lead to the fact that upon your return you will be greeted not by fresh cold, but by a persistent smell of mold and dampness, which will be extremely difficult to get rid of.
In this article we will analyze each stage of preparation refrigerator compartment for preservation. You will learn why you should not leave equipment dirty, how to properly dry internal cavities and whether seals need to be lubricated. Compliance with these recommendations ensures that after switching on the unit will immediately work like new.
Why is it important to properly preserve equipment
The main reason for careful preparation is bacterial activity. Even after defrosting, microscopic food particles remain in the microcracks of the plastic and the folds of the seals. In the warm, humid environment of an enclosed space, they begin to rot. The result is the formation of mold, which is able to penetrate deep into the structure of materials.
The second aspect is the technical condition. If moisture remains in the system, it can cause corrosion of metal components, especially in the solder areas of the evaporator tubes. In addition, incorrect positioning of equipment during transportation or storage (for example, on a balcony) can lead to oil leakage into the refrigerant circuit.
⚠️ Attention: It is strictly forbidden to leave food in the chamber, even frozen, if you plan to turn off the power. When defrosted, they will become a source of infection and can damage plastic shelves due to ice expansion.
It is also worth considering the condition compressor. A sudden switch on after a long period of inactivity without prior acclimatization (if the equipment was stored in the cold) can lead to water hammer. The oil in the compressor thickens in the cold, and starting the engine with thick lubrication is tantamount to running “dry” in the first seconds.
Preparation stages: defrosting and cleaning
The first and most important step is to completely empty the unit of its contents. Do not try to speed up the defrosting process by using a hairdryer or hot water - this may lead to deformation of the plastic elements of the evaporator. Allow the ice to melt naturally.
After the ice has melted, it is necessary to carry out general cleaning. Use a soft sponge and neutral detergent. Aggressive chemicals can damage the coating of the internal walls. Pay special attention to the corners of the chamber and the drainage hole, which often becomes clogged with mucus.
- 🧼 Thoroughly wash all removable shelves, drawers and egg trays in warm water with the addition of soda.
- 💧 Wipe the inner walls with a solution of vinegar or citric acid to disinfect and eliminate odor.
- 🌬️ Pay special attention drainage system: clean the condensate drain hole with a special flexible brush.
- 🚫 Do not use abrasive powders and hard metal sponges, which leave micro-scratches.
After wet cleaning, it is critically important to perfectly dry the interior. Moisture is the main enemy during long-term storage. Leave the doors open for several hours, allowing for a draft in the room. Only the complete absence of moisture guarantees that no fungus will grow inside.
☑️ Preparation checklist
Treatment of seals and external surfaces
The rubber door seal is an element that suffers from downtime in the first place queue. Rubber tends to dry out, crack and deform if it is not taken care of. Before preservation, it must be washed with soapy water and wiped dry.
To preserve the elasticity of the rubber, it is recommended to treat it with special means. In a professional environment, silicone grease or regular glycerin are often used. This will prevent cracking of the material and maintain its airtight properties.
External walls also require maintenance. If the refrigerator is in the kitchen, grease may have accumulated on it. If the equipment is put away in a storage room or garage, wipe it off from dust. For coated models stainless steel use special polishes that leave a protective layer.
Don't forget to check the door hinges. If you leave the refrigerator in a house with children or animals, make sure that the door locking mechanism works correctly, or use an additional stopper to prevent the door from slamming accidentally.
Features of storage in an unheated room
Storing a refrigerator on a balcony, in a garage or a country house in winter has its own nuances. Most modern models are designed to operate at temperatures from +10 to +32 degrees Celsius. Exceeding these limits can be dangerous for equipment.
Low temperatures make plastic brittle. Any careless movement or impact can lead to cracks. In addition, cold air contains less moisture, but with a sharp temperature change (introduced into heat), condensation forms on the parts, which threatens a short circuit.
| Parameter | Influence of cold | Recommendation |
|---|---|---|
| Compressor oil | Thickens, loses properties | Do not turn on for 24 hours after bringing into heat |
| Rubber seal | Turns, cracks | Treat with silicone, avoid direct rays |
| Electronics | Oxidation of contacts | Protect from moisture and rodents |
| Plastic parts | Become brittle | Do not expose to mechanical stress |
It is also important to protect equipment from rodents, which often live in garages and country houses. They can chew through wiring or make a nest in the thermal insulation of the case. Cover the ventilation openings with mesh, if possible.
⚠️ Attention: If your refrigerator is stored at temperatures below +5°C, do not try to turn it on immediately after bringing it into a warm room. Let it warm up to room temperature for at least a day.
Do you need to leave the refrigerator on?
A frequent question: is it worth leaving the appliances running at minimum if there is no one in the house? The answer depends on the length of the absence. If you are leaving for 2-3 weeks, it is easier to leave the refrigerator in operating mode, having first emptied it of food.
However, if your absence is planned for a month or more, it is economically and technically more expedient to turn off the unit. An idle one compressor wears out, energy is consumed, and the risk of power surges in the network remains.
Modern models with the system No Frost can independently switch to energy saving mode, but this does not eliminate the need cleaning. An empty refrigerator will (often) turn on the compressor, trying to cool the extra volume of air each time it is opened (if someone comes in), which is ineffective.
The myth of the “rest” of the compressor
There is an opinion that the compressor should be allowed to “rest” by turning it off for the summer. This is not true. Modern units are designed to operate 24/7. Downtime harms them more than constant operation, since the lubricant stagnates and the seals dry out without a working cycle.
If you still decide to leave the equipment on, set the temperature to +4...+5°C. This is enough to prevent mold from growing inside, and will avoid frequent defrosting cycles (for drip systems).
Fixing doors and dust protection
When transporting or storing in a cluttered room, the refrigerator doors must be secured. However, in contrast to transportation, during stationary storage for a long period, on the contrary, it is better to keep the doors slightly open.
Why is this important? A completely closed chamber without air circulation is an ideal environment for the development of anaerobic bacteria and mold, even if the refrigerator is clean. A minimum gap will ensure ventilation.
- 🚪 Use the standard fasteners for the transport bolts, if any, but do not tighten the door tightly.
- 📦 If there are no fasteners, you can insert rolled paper or cardboard between the door and the body.
- 🛡️ Cover the equipment with breathable material (an old sheet, a fabric cover) to protect it from dust, but do not use polyethylene.
Polyethylene film creates a “greenhouse effect”. If even a drop of moisture remains inside, an active process of corrosion and rotting will begin under the film. The fabric cover will allow air to circulate while trapping dust.
First startup after a long period of inactivity
When you return home, do not rush to immediately load the products. First, conduct a visual inspection for damage, rodents, or signs of corrosion. Wipe the internal surfaces with a damp cloth, as dust may have settled during inactivity.
Plug in the empty refrigerator. Let it run without load for 2-4 hours. This will allow the system to reach operating temperature conditions, and the oil in the compressor to be evenly distributed throughout the system.
If after turning on you hear an unusual noise, or the refrigerator does not freeze for 6-8 hours, there may be a freon leak or a breakdown of the start relay during the downtime. In this case, diagnostics will be required.
Is it possible to store the refrigerator lying down?
You can transport the refrigerator lying down, but not on the back or on the front panel. Only on its side, and be sure to let it stand vertically before turning it on (at least 4-8 hours, preferably a day) so that the oil flows into the compressor.
What to do if an odor appears after turning it on?
If the smell is weak, activated carbon left inside for a day or special odor absorbers will help. If there is a chemical or burning smell, immediately turn off the device and call a technician; the wiring or insulation may have burned out.
Do you need to lubricate the hinges with oil?
It is better not to use ordinary machine oil - it attracts dust and can stain clothes. For hinges and seals, it is better to use silicone grease, which is odorless and does not stick.
Is it dangerous to leave a refrigerator on the balcony in winter?
Yes, it is risky. Frost destroys plastic and rubber, and moisture causes corrosion. If there is no other way out, cover the unit with a thick, waterproof but breathable cover and do not turn it on until complete acclimatization in the heat.
