The need to turn off a two-chamber refrigerator occurs infrequently, but always requires a careful approach. This could be a planned defrosting of the system No Frost, general cleaning in the kitchen, or a long-term departure of the owners for several months. Incorrect actions during this period can lead to the appearance of a persistent unpleasant odor, the growth of mold inside the ducts, or even breakdown of the compressor the next time it is started.
Many people mistakenly believe that it is enough to simply unplug the cord from the outlet and close the door until the next visit. However, this approach is a gross technical error. The internal space of the unit must remain dry and ventilated to prevent corrosion of the evaporator and degradation of seals. Modern models LG, Bosch or Indesit have their own nuances of preparation for conservation that are worth considering.
In this article we will analyze in detail the algorithm of actions that will allow you to preserve performance of your equipment for many years. We will consider the stages of defrosting, washing, drying and proper preservation of equipment. Compliance with these rules will help avoid costly repairs and ensure that after switching on the unit will work like new again.
Preparing for shutdown and defrosting the system
The first and most important step is to completely empty the refrigeration chambers of food. Do not try to leave frozen supplies “for later” or turn off the unit for a couple of hours - this will spoil the contents and create an ideal environment for bacteria. Plan your menu in advance to use perishable foods, or distribute them into cooler bags with refrigerant if the outage is planned for a short period.
After removing the food, you need to defrost refrigerator and freezer compartments. Even if you have a system installed Total No Frost, condensation remains inside, which will turn into water when the compressor stops. For models with a drip system, this stage is critically important, since the ice crust on the evaporator must completely melt naturally.
It is strictly forbidden to use a hairdryer, hot water or sharp objects to speed up defrosting. A sudden change in temperature can cause cracks in the plastic inner box or damage the evaporator tubes, which will lead to a freon leak. The process should take place with the doors open and room temperature.
⚠️ Attention: If you are the owner of a model with the system No Frost, remember that water can accumulate in hidden drainage channels. Make sure the condensate tray under the compressor (lower back) is empty before you start washing.
To speed up the process, you can place thick terry towels on the shelves to absorb moisture. Change them periodically to dry ones. The time for complete defrosting can vary from 4 to 24 hours depending on the amount of ice and the temperature in the room.
Procedure for turning off the power supply and removing components
When the ice has completely melted and the water has been collected, you can proceed to a technical shutdown. First, make sure your hands are dry before unplugging the power cord from the electrical outlet. Sharply pulling the cord by the wire is prohibited - this may damage the insulation or contacts of the plug, which creates the risk of a short circuit in the future.
Next, you need to remove all removable elements: glass shelves, plastic containers, vegetable drawers and bottle holders. They should be washed separately with warm water and a mild detergent. Glass shelves cannot be washed with hot water immediately after being in the cold - they may burst due to thermal shock.
Inspect sealing rubber bands on the doors. Dirt and crumbs often accumulate in the folds, which can cause mold if left unused for a long time. Wipe them gently with a damp sponge. If the rubber has visible damage or has lost its elasticity, you should think about replacing it before a long period of inactivity, since the door pressed in one position can deform the damaged area even more.
Do not forget to move the refrigerator away from the wall to provide access to the back panel. This is necessary for inspection of the condenser array and compressor. There should be no balls of dust that, when the motor is running, can cause it to overheat after switching on.
☑️ Preparation checklist
Washing and disinfection of internal surfaces
Cleanliness inside the chambers is the key to the absence of odor after a long period of inactivity. To wash the inner walls, it is best to use a baking soda solution (1 tablespoon per liter of water) or special household appliance products. They effectively remove fat deposits and do not require careful rinsing, unlike aggressive chemicals.
Pay special attention to the drainage hole, which is usually located on the back wall of the refrigerator compartment. It may be clogged with food debris. You can clean it using a special flexible brush or cotton swab. Clogging of this channel is a common reason for the appearance of puddles under the refrigerator when first starting up.
After treating with detergent, be sure to wipe all surfaces with a clean damp cloth, and then wipe dry with paper towels. Moisture - the main enemy when preserving equipment. The remaining water in the corners or joints of the plastic will become a breeding ground for microorganisms.
| Cleaning zone | Recommended product | Frequency during preservation |
|---|---|---|
| Internal walls | Soda solution or special. spray | Required |
| Seals | Warm water, vinegar solution | Required |
| Drain hole | Warm water, brush | As needed |
| External body | Glass cleaner/polish | As desired |
For the outer body, use products that match the coating material. It is better to wipe stainless steel (Stainless Steel) with special polishes along the metal fibers to avoid micro-scratches and streaks.
Drying and airing before preservation
The most critical stage, which is often ignored, is complete drying. Even if you thoroughly dry the surfaces with a towel, moisture remains in the micropores of the plastic and in hard-to-reach places. The refrigerator should stand with the doors open for at least 24 hours in a dry, ventilated room.
If you plan to turn off the appliance for the summer at the dacha, make sure that the humidity in the room is not too high. In damp, unheated houses, metal may begin to oxidize faster. Ideally, the room temperature should be room temperature and the humidity should be moderate.
How long does it take for a refrigerator to dry?
It takes 1 to 2 days for complete evaporation of moisture from hidden cavities and thermal insulation. Do not close the doors until you are sure that the inside is completely dry and there is no damp smell.
Some users use fans to speed up the circulation of air inside the chambers. This is a valid method that helps remove moisture from porous materials faster. However, you cannot direct the flow of hot air from the heater directly onto the plastic - this can lead to its deformation.
Check the dryness with a cotton swab in the corners of the chambers and around the shelf fastenings. If the stick remains dry, the process is completed successfully. Only after this can you proceed to fixing the doors.
How to properly fix the doors
The main rule for preserving a refrigerator is that the doors should not be tightly closed. If you leave the unit closed, a “thermos” with high humidity will quickly form inside, which is guaranteed to lead to the appearance of mold and a musty smell, which is then very difficult to get rid of.
However, wide open doors are not the best option, especially if there are children or pets in the house. They could accidentally slam them shut, damage the seal, or worse, get stuck inside. In addition, constantly open doors can sag under their own weight, which will disrupt the geometry of the hinges.
The optimal solution is to fix the doors in the slightly open position. A gap of 2-3 centimeters is enough for natural air circulation. For fixation you can use:
- 🧷 Special transport clamps (often included with a new refrigerator).
- 📏 A rail or block installed vertically between the upper and lower doors (for two-chamber models).
- 🧶 Thick fabric or belt, lightly stretched between the handles, preventing the doors from slamming.
⚠️ Attention: Never use glue, tape or adhesive tape to fix the doors in the open position for a long period of time. The adhesive base may melt or dry out, leaving permanent marks on the body, or damage the paintwork when removed.
Transportation and storage in an unheated room
If the refrigerator is turned off for transportation or storage in the country in winter, come into force additional rules. Transportation possible only in a vertical position. Tilt of the unit by more than 40 degrees is dangerous: oil from the compressor can flow into the refrigerant circuit, which will lead to water hammer at the first start.
When stored in an unheated room (garage, balcony), there is a risk of damage to plastic elements and seals due to temperature changes and ultraviolet radiation. If there is no other option, cover the equipment with a breathable material, such as a cotton sheet, but do not use plastic film, which will create a greenhouse effect.
It is important to remember temperature restrictions. Most manufacturers do not recommend operation and storage at temperatures below -5°C or above +35°C. Frost makes the plastic brittle and the seals lose their elasticity. Heat can cause the inner plastic to delaminate.
Before final packaging, make sure that all compressor mounting bolts (transport bolts) are tightened if the equipment will be subject to vibration during transportation. This will prevent damage to the motor mount.
Common mistakes during prolonged downtime
One of the common mistakes is trying to preserve the refrigerator with residual moisture. Even a small puddle in the drainage pan will turn into a source of a persistent smell of rot in a month. Removing it can be more difficult than it seems: you need to disassemble the inner lining or use an ozonizer.
Another mistake is storing detergents, sponges or foreign objects inside the unit. Chemical fumes can be absorbed into the plastic, and a forgotten damp sponge can become an ideal incubator for bacteria. You can only put an odor absorber inside (activated carbon, silica gel), but not household chemicals.
You should also not leave the refrigerator plugged in, but empty, “just in case.” This does not make sense, since the thermostat will still periodically start the cooling cycle, consuming electricity and wearing out the life of the compressor without a useful load.
Is it possible to store the refrigerator lying down?
Transportation in a lying position is extremely undesirable. If this is unavoidable, place the unit on the side opposite the side where the compressor tubes exit (usually the right side when viewed from the rear, but it is better to check the instructions for the specific model Indesit or Atlant). After such transportation, the refrigerator must stand upright for at least 12-24 hours before turning it on.
What to do if a smell appears after turning it on?
If a smell appears after inactivity, wash the chambers with a solution of vinegar or citric acid. Place activated carbon tablets, ground coffee or special odor absorbers inside. Let the equipment work empty for 24 hours with open containers for sorbents.
Do you need to lubricate the hinges with oil?
For long-term downtime (more than 6 months), it is recommended to lubricate the door hinges with silicone grease. This will prevent the factory lubricant from drying out and causing squeaking. It is better not to use ordinary machine oil, as it can thicken in the cold or attract dust.
Is downtime dangerous for a compressor?
Downtime itself is not dangerous for a working compressor. Moisture and corrosion that can occur inside the system if it is not properly preserved are dangerous. If the refrigerator was clean and dry before turning off, it can stand for years without damage to the motor.
Following these simple but important rules will allow you to keep your two-chamber refrigerator in excellent condition. Proper preparation for downtime is an investment in the durability of the equipment, which will pay off in the absence of the need for complex repairs or replacement of seals after returning from vacation or the winter season.
