With the onset of cold weather, many owners of dachas or country houses are faced with the issue of preserving household appliances, especially if the room is not constantly heated. Leaving refrigerator on in an unheated house for the whole winter is not only expensive, but also risky for the unit itself due to voltage drops and low oil temperatures in the compressor. However, simply turning off the device, forgetting about it until spring, means guaranteeing the appearance of a persistent smell of mustiness, mold and, possibly, corrosion of internal elements.
Proper preservation requires a series of sequential actions aimed at removing moisture, protecting against dust and preventing deformation of the seals. In this article, we will analyze in detail each stage of preparing your equipment for winter hibernation, so that in the spring it will work like new again.
The preparation process does not take much time, but it requires attention to detail, which is often ignored by users. This is especially true for the drainage system and the condition of rubber seals, which, if stored improperly, can dry out or become covered with microcracks.
Assessment of storage conditions and temperature restrictions
Before taking active steps, it is necessary to objectively assess the conditions in which the equipment will be located. Modern models, especially those equipped with the No Frostsystem, are sensitive to extremely low temperatures, even when turned off. If the room temperature drops below -5°C, it can adversely affect the plastic, paintwork and, more critically, the refrigerant and oil.
It is important to understand the difference between “cold storage” and “freezing”. For most household appliances, the optimal temperature range is from +5°C to +25°C. If your country house freezes through, you should think about additional insulation of the installation site or dismantling the most vulnerable components.
⚠️ Attention: It is strictly forbidden to store the refrigerator at temperatures below
-20°C. At such values, plastic becomes brittle, and metal elements are subject to accelerated corrosion due to condensation during temperature fluctuations.
It is also worth considering the humidity in the room. A damp basement or garage with poor ventilation is the worst place to winter equipment. In such conditions, the risk of oxidation of contacts and the appearance of fungal spores on the internal walls increases many times, regardless of how thoroughly you dry the chamber.
Complete defrosting and removal of food
The first and most obvious step is to completely empty the refrigerator and freezer compartments from the content. You shouldn't try to save supplies if you don't plan to use the equipment in the coming months. Even a short-term power outage can lead to spoilage of food and the growth of bacteria, the smell of which will then be very difficult to remove.
After removing the food, it is necessary to carry out the defrosting procedure. If you have a manual defrost model, this process will take from 4 to 12 hours depending on the thickness of the ice. To speed up the process, you can use special tools, but never use a hair dryer, hot water or sharp objects to chip ice. A sharp temperature change can lead to cracks in the evaporator, and mechanical stress can lead to damage to the freon tubes.
In the case of the system No Frost or Low Frost ice visually may not be visible, but moisture is still present in the form of frost on hidden elements. Leave the appliance turned off with the doors open for at least 24 hours. This time is usually enough to evaporate residual moisture from hard-to-reach places.
☑️ Defrosting stages
Deep cleaning and disinfection of internal surfaces
Simply wiping the shelves with a damp cloth is not enough. During operation, bacteria and mold spores could settle on the walls of the chamber and begin to actively multiply in a confined space. For high-quality cleaning, use a weak solution of baking soda (1 tablespoon per liter of water) or special products for cleaning refrigerators without abrasive particles.
Pay special attention to the corners of the chamber and the places where the shelves are attached. This is where dirt most often accumulates, which serves as a breeding ground for microorganisms. After wet cleaning, be sure to wipe all surfaces with a dry cloth. Remaining moisture is the main enemy during long-term storage.
Don't forget to remove and wash separately all removable elements: glass shelves, plastic containers, egg trays and bottle holders. It is better to store them separately, wrapped in cloth, to avoid accidental damage or scratches. During sudden cooling, glass shelves may break if moisture remains on them or if they lie on a cold floor.
| Refrigerator element | Cleaning agent | Processing features |
|---|---|---|
| Internal walls | Soda or vinegar solution | Avoid getting moisture into the holes |
| Rubber seal | Warm water, glycerin | Treat with glycerin for elasticity |
| Glass shelves | Glass cleaner | Store vertically or on a soft substrate |
| Plastic boxes | Soap solution | Dry to avoid fragility |
Treatment of seals and external surfaces
The rubber door seal is one of the most vulnerable elements. In frost or dry air, it can crack, lose elasticity and stop sealing the chamber hermetically. To prevent this, after cleaning and drying, wipe the seal with a glycerin solution or a special silicone grease.
External surfaces also require maintenance. The metal body should be wiped clean from dust and possible grease stains. If there are chipped paint on the body, it is advisable to paint over them to prevent the development of corrosion, which can occur faster in winter due to condensation.
How to lubricate the seal?
To treat rubber seals, it is best to use pharmaceutical glycerin or special silicone lubricants based on silicon dioxide. Do not use vegetable oil - it oxidizes over time, sticks and can cause an unpleasant odor and bacterial growth.
After processing, allow the grease to soak in for 30-60 minutes before closing the doors. This will ensure uniform distribution of the protective layer and prevent rubber from sticking to the metal body.
Protection from dust, rodents and insects
When the internal chambers are perfectly clean and dry, it is time for protection from external factors. Dust entering through the vents may cause a short circuit or electronic malfunction the next time you start up. In addition, warm interior spaces often attract rodents, which can chew on wire insulation.
For protection, use breathable materials such as cotton fabric or old sheets. Close the refrigerator completely, paying particular attention to the back where the compressor and radiator are located. Do not use plastic film to wrap tightly - it creates a greenhouse effect and promotes the formation of condensation.
⚠️ Attention: Do not seal the ventilation holes tightly. There should be minimal air circulation so that a “bath” does not form inside when the temperature fluctuates.
If storage takes place in a garage or shed where mice are found, place strong-smelling substances around and inside (on shelves if they are removed): cotton wool soaked in mint essential oil, or special ultrasonic repellers powered by batteries. Chemical poisons cannot be used inside equipment.
Features of transportation and installation
If you plan not only to preserve, but also to transport the refrigerator to another place for wintering, follow the transportation rules. Equipment can only be transported in an upright position. An inclination of more than 40 degrees can lead to oil flowing from the compressor into the refrigerant circuit, which will cause an oil plug and failure of the compressor upon first start-up.
After delivering the refrigerator to its winter storage location (or back home in the spring), do not turn it on immediately. Allow the equipment to acclimatize for 3-4 hours if it was transported warm, and up to 24 hours if it was frozen. The oil should drain back into the compressor crankcase, and the condensate on the contacts should evaporate.
Install the device on a flat surface, twisting the legs so that the door closes itself under its own weight (slight tilt back). This will ensure proper fit of the seal.
Frequently asked questions (FAQ)
Is it possible to store a refrigerator on the balcony in winter?
Storage on an unglazed balcony is extremely undesirable due to direct exposure to precipitation, ultraviolet radiation and critically low temperatures. On a glazed balcony, this is possible if the temperature does not drop below -5°C and the equipment is not exposed to direct sunlight that heats the body.
Do you need to leave the doors open for the winter?
Yes, this is a prerequisite. If you close the doors tightly, moist air will remain inside, which will lead to the appearance of mold and a persistent musty odor. For safety (protection from children and animals), the doors can be fixed in the slightly open position using a belt or tape, leaving a gap of 2-3 cm.
What to do if after winter the refrigerator hums, but does not cool?
Most likely, oil has leaked into the circuit or an ice plug has formed in the capillary tube. Try leaving the device turned off for another 12-24 hours in a warm room. If the problem is not solved, you will need to call a technician to purge the system or change the oil.
Are temperature changes dangerous for refrigerator electronics?
Sudden temperature changes can lead to the formation of condensation on control boards, which causes corrosion of contacts and short circuits. That is why gradual acclimatization of equipment before switching on and a dry storage room are important.
How to get rid of the smell after winter storage?
If the smell does appear, wipe the inner walls with a solution of citric acid or vinegar. Adsorbents help well: activated carbon, soda in an open container, or special odor absorbers that need to be left inside a closed refrigerator for 2-3 days.
