With the onset of cold weather before each The owner of a country property is faced with the question of preserving household appliances, and it is especially acute for those who do not know how to leave a refrigerator in the countryside for the winter. Improper preparation of the unit for long periods of inactivity in an unheated room can lead to failure of the compressor, the appearance of mold inside the chambers and even rupture of the cooling system tubes.
Many people mistakenly believe that it is enough to simply unplug the cord from the socket and slam the door, but such carelessness is fraught with serious consequences. Low temperatures, changes in humidity and rodent activity are the three main enemies that can destroy equipment in one season. In this article we will look at all the nuances so that your Indesit, Atlant or LG safely survives until spring.
It is important to understand that the preservation process depends not only on the brand of the device, but also on the type of refrigerant that is used in it. Modern models may differ significantly from Soviet analogues in storage times temperature requirements.
The influence of low temperatures on refrigerator components
The main danger for equipment left in the cold lies in the physical properties of the materials from which it is assembled. Compressor oil, located in the motor, thickens and thickens when subjected to strong cooling. loses its lubricating properties. If you try to start such a unit without pre-warming, the piston group may jam, which will lead to expensive repairs.
The condition of the refrigerant is even more critical. In systems where it is used freon R600a (isobutane)which is explosive at a certain concentration, the integrity of the circuit is doubly important. Sudden temperature changes cause compression and expansion of the metal tubes of the evaporator and condenser.
⚠️ Attention: It is strictly forbidden to turn on a refrigerator that has just been brought from the cold into the heat. It is necessary to wait at least 4-6 hours (or better yet, a day) for condensation formed inside the electrical circuits to acclimate and evaporate.
Plastic elements of the internal lining also suffer from the cold. Cheap plastic becomes brittle at temperatures below -5°C, and careless movement or impact can lead to cracks on shelves or door handles.
Why can't you keep the refrigerator on in the cold?
If you leave the refrigerator on on an unheated veranda, the thermostat may not work to turn off the compressor at low ambient temperatures, which will lead to idle operation and rapid wear of the motor.
Proper defrosting and removal of moisture
The first and most important stage of preparation is complete defrosting. Even if your model is equipped with a No Frostsystem, pockets of moisture may remain inside, which will expand when frozen and damage the seals. The process takes time, and you cannot rush it with artificial heating (hairdryer or heater).
After the ice has completely melted, you must thoroughly wash the internal surfaces. Use a weak soda solution or special household appliance cleaners to remove grease and food residues. Any organic matter remaining inside will become an ideal environment for the growth of bacteria and the appearance of a musty smell by spring.
Pay special attention to the drainage hole, if your model has one. It must be cleaned with a brush or soft wire to ensure there are no blockages. Water in the drainage should not stagnate.

Preservation of the compressor and electrics
When the issue with moisture is resolved, we move on to the technical part. Many owners forget that the compressor is sealed, but its external contacts and terminal box can oxidize due to dampness. It is recommended to visually inspect the back wall for damage to the wire insulation.
If you plan to leave the equipment in a garage or shed where voltage surges in the network are possible (for example, when neighbors connect a generator), it is better to completely disconnect the input cable or use a reliable surge protector, although in winter the network is usually de-energized. The main thing is to make sure that thermostat is set to the minimum position before the final shutdown.
To protect against power surges in the future, when you return to the dacha, it makes sense to install a voltage control relay. This device will turn off the power if the voltage in the network is too high or low, saving the motor from burning out.
Protection from rodents and pests
Winter for mice and rats is a hungry time, and they will gladly sneak into the warm (or simply closed) space of the refrigerator in search of leftover food. But the main danger is not food, but isolation. Rodents often chew through wires or build nests in the thermal insulation of the building, which is discovered with horror in the spring.
To prevent the invasion of uninvited guests, use proven repellents. Place cotton pads soaked in peppermint essential oil inside the chambers and next to the unit, or special self-powered ultrasonic repellers, if it is possible to leave them.
It is also important to close all ventilation holes with a fine metal mesh if the design of your country house allows rodents to penetrate inside the walls or under the floor. Mice can fit into a hole the diameter of a pencil.
⚠️ Attention: Do not use pesticides inside refrigerator compartments. If a rodent dies inside thermal insulation or a hard-to-reach cavity, it will be impossible to remove it, and the smell will persist for years.
Comparison of storage conditions for different types of refrigerators
Not all refrigerators tolerate wintering equally. Old Soviet models with cast iron evaporators are more resistant to cold than modern Chinese or European units with aluminum tubes and complex electronics.
The table below shows the main risks for different types of equipment when stored at temperatures below 0°C:
| Refrigerator type | Critical temperature | Main risk | Recommendation |
|---|---|---|---|
| Soviet (ZIL, Saratov) | Below -15°C | Rubber cracking | Store in dry place |
| Modern No Frost | Below -5°C | Damage to plastic, electronics failure | Heated room only |
| Gas unit R600a | Any minus | Depressurization of seams at startup | Strict acclimatization |
| Built-in equipment | Below +5°C | Mold in the cabinet niche | Ensure ventilation of the niche |
As can be seen from the table, modern models are much more demanding on environmental conditions. Electronic control boards are sensitive to condensation that forms on cold chips when humidity rises.
Final packaging and installation
After the refrigerator has been washed, dried and treated for rodents, it must be installed correctly. The main rule: the doors should remain slightly open. This will ensure air circulation and prevent the appearance of musty smells and mold.
To fix the doors in the open position, use standard shipping bolts (if you still have the instructions and fasteners) or simple spacers made of cardboard and foam. Some models have a special transportation mode that secures the shelves and doors.
It is better to cover the top of the unit with a breathable cloth or an old sheet to protect it from dust, but do not wrap it in plastic. If direct sunlight is possible in the room, make sure that it does not fall on the body, as ultraviolet radiation destroys plastic and paint.
⚠️ Attention: Never place heavy objects on the horizontal surface (roof) of the refrigerator. The thin metal of the roof can bend, damaging the thermal insulation or condenser tubes hidden inside the walls.
Frequently asked questions about winterizing a refrigerator
Is it possible to leave the refrigerator turned on at minimum in the winter?
No, this is highly undesirable. If the room temperature drops below the minimum thermostat operating threshold (usually +10...+14°C), the compressor either will not turn on or will not work correctly, which will lead to its breakdown. In addition, in an unheated house, voltage surges are possible that are dangerous for electronics.
Do you need to lubricate the seals before winter?
Yes, that’s a great idea. Rubber seals become tanned in the cold and may crack. Wipe them with a glycerin solution or a special silicone grease for rubber. This will preserve the elasticity and tightness of the doors until the next season.
What to do if there is a mold smell inside in the spring?
Do not rush to turn on the device. Rinse all surfaces thoroughly with a solution of vinegar or citric acid. Place odor absorbers inside (activated carbon, soda). Leave the refrigerator open to air for a couple more days. If the smell does not go away, mold may have penetrated into the insulating layer, and then professional cleaning or replacement of the insulation will be required.
Is the gas in the refrigerator dangerous if the case is damaged?
Modern refrigerators use a small amount of refrigerant. Freon R134a is inert and non-toxic in small doses, but displaces oxygen. Isobutane (R600a) flammable. However, the amount of gas in the circuit (usually 30-60 grams) is too small for a serious explosion in an open space, but if the pipes are damaged in a closed room, it is better to ventilate it before starting work.
