Making a decision to decommission large-sized household appliances is often associated with moving, long-term departure or replacing the device with a larger one modern model. However, the simple process of removing the plug from the socket is only the beginning of a complex procedure that requires careful attention to detail. Improper preparation can lead to failure of the compressor, the appearance of mold inside the chambers or damage to the seals during transportation.
Many owners underestimate the importance of the stage preparing for shutdown, believing that it is enough to simply wait for defrosting. In reality, ignoring the rules for preserving the cooling system is fraught with expensive repairs after restarting. This is especially true for units that will be idle without electricity for more than two to three weeks.
In this article we will analyze in detail the algorithm of actions that will allow you to maintain the functionality of your equipment. You'll learn how to safely drain the refrigerant (if it's a repair), how to prepare interior surfaces, and why you shouldn't immediately close the doors after defrosting. A competent approach will ensure that the equipment will serve you for many years after inactivity.
Preparation for shutdown and defrosting
The first and most important stage is emptying the chambers of food. You should not try to preserve supplies by putting them in ice packs if you are planning a long shutdown - it is better to consume them in advance. After this, you need to turn off the power device by unplugging the plug from the network and set the temperature regulator to the “0” or “Off” position.
Next follows the process of natural defrosting. It is strictly forbidden to use sharp objects to chip ice or hair dryers to speed up the process, as this may damage the evaporator. Water formed during melting must be removed in a timely manner so as not to flood the floor and damage the lower elements of the case.
It is important to ensure air access to the internal shelves. To do this, all removable elements - shelves, drawers, containers for vegetables - should be removed and washed separately with warm water and a mild detergent. This will avoid the appearance of a musty smell in the future.
⚠️ Attention: Never plug in the refrigerator immediately after defrosting or transporting it. The oil in the compressor takes time (from 2 to 8 hours) to drain back into the crankcase, otherwise water hammer and damage to the unit are possible.
Cleaning and disinfection of internal surfaces
After complete removal of ice and moisture, the general cleaning stage begins. The inner walls of the chambers are often covered with bacteria invisible to the eye, which, in the absence of cold, begin to actively multiply, causing corrosion of the plastic and the appearance of a persistent unpleasant odor. For cleaning, it is recommended to use a baking soda solution or specialized products for household appliances.
Particular attention should be paid sealing rubber bands to the doors. It is in the folds of the material that dirt and mold most often accumulate. Wipe them with a soft cloth soaked in a vinegar solution, which will not only clean, but also disinfect the surface, maintaining the elasticity of the rubber.
After wet cleaning, all surfaces should be thoroughly wiped dry. The remaining moisture is an ideal environment for the development of fungus. The doors at this moment should be wide open to ensure maximum air circulation.
Preservation for long-term storage
If the refrigerator is turned off for more than a month, proper preservation is necessary. The main task is to prevent mold and corrosion. After the final drying of the insides, it is recommended to leave the doors slightly open. This can be done by inserting a small block or rolled-up rag between the body and the seal.
To protect external surfaces from dust and scratches when storing in a garage or warehouse, use breathable materials, such as old sheets or a special covering fabric. Polyethylene film is not suitable, as it creates a greenhouse effect and promotes the accumulation of moisture.
| Duration of downtime | Position of doors | Temperature conditions | Necessity of drying |
|---|---|---|---|
| Up to 3 days | Closed | Any | Not required |
| From 3 to 30 days | Ajar | Dry room | Required |
| More than 1 month | Fixed open | Warm, dry | Careful processing |
| Transportation | Fixed with tape | Any | Required |
It is important to choose the right storage location. It must be protected from direct sunlight and temperature changes. Sudden changes in temperature conditions can negatively affect the condition of the plastic and paintwork of the case.
Preparation for transportation and moving
Before transportation, the refrigerator must not only be defrosted, but also securely secured. It is better to pack all removable parts (shelves, drawers) separately, wrapping them in bubble wrap or paper. This will prevent them from fighting and damaging the inner walls of the chamber when shaking.
The doors should be tightly closed and secured with masking tape or belts so that they do not swing open on the way. However, remember that immediately after delivery to a new place they need to be opened for ventilation.
☑️ Checklist before loading
When moving the unit, it is important to respect its spatial position. Most models can only be transported in an upright position. An inclination of more than 40 degrees can lead to oil leakage into the refrigerant circuit, which will require a long period of settling before the first start-up.
Dismantling and recycling of old equipment
If your goal is not to preserve, but to recycle the old refrigerator, the procedure changes. First of all, you need to provide access to the rear panel of the device. Here you will need a screwdriver and possibly a wrench.
The process of dismantling the compressor and pipe system requires caution. In older models (Zil, Biryusa, Minsk), freon could be used as a refrigerant, which should not be released into the atmosphere. Although in domestic conditions complete pumping out of gas is difficult, it is recommended to make a hole in the evaporator tube in a well-ventilated area so that the gas comes out in a controlled manner.
⚠️ Attention: Burning wire insulation or plastic parts of the refrigerator to obtain metal is strictly prohibited. When burned, they release toxic substances that are hazardous to health and the environment.
To be sold as scrap metal or at a specialized collection point, the equipment must be freed from plastic elements and seals. The metal case, compressor and radiator grille are accepted as ferrous scrap, and the copper condenser tubes are accepted as non-ferrous metal, which can slightly offset the cost of removal.
Frequent errors when disconnecting
One of the most common mistakes is trying to quickly defrost the refrigerator using boiling water or a hairdryer. Sudden temperature changes can lead to cracks in the plastic and deformation of the evaporator. In addition, contact of hot water with electrical contacts is unacceptable.
Another mistake is storing the refrigerator with the doors closed in a damp room (garage, basement) without pre-drying. Under such conditions mold appears in a matter of days, penetrating into the pores of the plastic. It is almost impossible to remove the afterward smell, and the equipment has to be thrown away.
What to do if the smell appears after standing for a long time?
If the smell has already appeared, try wiping the internal surfaces with a solution of ammonia (1 tablespoon per liter of water) or activated carbon. Leave the doors open for several days.
Do not ignore the manufacturer's instructions. Modern models with the system No Frost may have their own shutdown nuances, for example, the presence of additional drainage channels that also need to be dried.
FAQ: Frequently Asked Questions
How long should you wait before turning it on after transportation?
If the refrigerator was transported vertically, it is enough to wait 2-3 hours. If the device was lying on its side, the waiting time increases to 8-12 hours so that the oil completely drains into the compressor.
Is it possible to turn off the refrigerator at night to save money?
It is strictly not recommended. Frequent cycles of on and off, as well as defrosting of food, lead to increased wear on the compressor and increased energy consumption during re-cooling.
Do you need to lubricate the seals during long-term storage?
Yes, this will extend their service life. Use silicone grease or glycerin. This will prevent the rubber from drying out and losing its seal.
What to do with the water in the drainage tray?
The water must be removed. In models with a drip system, it is located in a bath above the compressor. It is usually accessed through the rear grille. Remaining water can cause corrosion of the metal.
