Modern household appliances significantly simplifies life, however, even advanced systems No Frost sometimes require intervention, not to mention models with a drip system. Sooner or later, every owner is faced with the need to carry out a complete defrost to remove ice, eliminate foreign odors, or simply wash the internal surfaces. Incorrect actions during this period can lead to damage to the compressor, refrigerant leakage, or failure of the electronics.
In this material we will analyze in detail the algorithm of actions for two-compartment refrigerators, where the freezer and refrigerator compartment are separated by a partition. You will learn why you should not use a hairdryer or knife to crush ice, how to speed up the natural melting process, and what to do with food while the equipment is turned off. Compliance with these rules will extend the life of your Indesit, Atlant or LG.
Preparing for the defrosting process
The first step is to completely unload the refrigerator. You need to remove all products, shelves and drawers. If it's winter outside, you can temporarily take perishable goods to the balcony, but make sure that they are not exposed to direct sunlight. In the summer, you will have to get creative: use thermal bags with ice or ask your neighbors to temporarily store some of the supplies.
After freeing up the space, disconnect the device from the power supply. Simply pulling the plug out of the socket is not enough if access to it is difficult - in this case, you need to turn off the machine in the panel. This is a critical safety step, as any manipulation of water or live electrical appliances is prohibited. Let the equipment stand for 10-15 minutes so that the pressure in the refrigerant system stabilizes.
Prepare a place to collect water in advance. In two-chamber models, melt water can flow not only downwards, but also through technological openings into the fridge compartment. Cover the floor around the refrigerator with old towels or newspapers, and place absorbent rags inside the chambers. This will save the laminate or linoleum from swelling.
⚠️ Attention: It is strictly forbidden to defrost the refrigerator if food is still stored in the freezer. Warm air and moisture will lead to deterioration of supplies and the growth of bacteria on the walls of the chamber.
Do not forget to remove all removable elements: glass shelves, plastic containers, bottle holders and egg trays. They should be washed separately with warm water and a mild detergent. Glass may burst under a sudden temperature change (if immediately washed with hot water after freezing), so let the parts warm up to room temperature.
☑️ Preparation checklist
Natural defrosting versus accelerated methods
The safest way to get rid of ice is to let it melt on its own. To do this, simply leave the refrigerator and freezer doors open. The process time depends on the thickness of the ice crust and the room temperature: it usually takes from 3 to 24 hours. In models with drip system ice there may be more ice than in No Frost.
Many users try to speed up the process by using a hairdryer, heater or containers of boiling water. Using a hairdryer is only permissible in cold blowing mode or at a minimum temperature from a distance of at least 30 cm. Heating plastic with hot air can deform the internal panels, and a sharp temperature change is dangerous for the evaporator tubes.
The method with bowls of boiling water works more efficiently. Place containers of hot (but not boiling) water on the freezer shelves and close the door. The steam will speed up the melting of the ice. Change the water as it cools. However, make sure that steam does not condense on the electronic control boards if they are located inside the chamber.
Why should you not chip the ice with a knife?
The evaporator tubes in modern refrigerators are often made of aluminum and run very close to the inner wall of the chamber. One careless movement with a knife or screwdriver can pierce the wall, which will lead to an instant release of freon and costly repair of the compressor.
If you choose a natural method, ensure good ventilation in the room. Opening the windows will help quickly dissipate the smell of old food and dampness that will inevitably appear when the ice melts. This will also help dry the internal surfaces faster after the procedure is completed.
Removing ice and flushing the system
When the bulk of the ice turns into water, you must thoroughly wipe all surfaces. Use a soft sponge and warm water. For disinfection, you can add a little vinegar or citric acid, which will also help eliminate unpleasant odors. Aggressive chemicals and abrasive powders cannot be used - they can damage the antibacterial coating.
Pay special attention to the drainage hole if it is provided for in the design of your model (often located in the rear wall of the refrigerator compartment). A clogged water drainage channel is a common cause of puddles appearing under the refrigerator. You can clean it with a special soft brush or a cotton swab dipped in warm water.
After wet cleaning, be sure to wipe all surfaces dry. The remaining moisture will be an ideal environment for mold to grow. Keep the doors open for at least another 2-3 hours after finishing wiping to ensure that hard-to-reach corners and rubber seals are completely dry.
| Stage | Action | Execution time | Risks of errors |
|---|---|---|---|
| 1 | Shutdown and unloading | 15-20 minutes | Product spoilage |
| 2 | Ice melting | 4-12 hours | Damage to the housing with a hair dryer |
| 3 | Washing and disinfection | 30-40 min | Use of abrasives |
| 4 | Drying and starting | 2-3 hours | Start with moisture |
Nuances for No Frost and Low Frost systems
Owners of refrigerators with the system No Frost (for example, Samsung, Bosch) often wonder: do they need to be defrosted? Technically, in such models, ice does not accumulate on the walls, since moisture is removed through a special channel. However, defrosting is required for hygiene and in the event of a defrost system failure, when the evaporator becomes overgrown with a “fur coat” inside the housing.
For equipment No Frost it is critically important not to pour water directly onto the back wall, where the ventilation holes and defrost heater are located. Water getting into this compartment can cause a short circuit or failure of the defrost heating element. Carry out washing only with a damp, well-wrung out cloth.
System Low Frost (often found in Liebherr i Bosch) assumes less ice formation, but does not eliminate it completely. Defrosting of such models follows the standard scenario, but takes less time due to the absence of a thick ice crust. 2-4 hours are enough for a full cycle.
If your refrigerator makes a strange hum after defrosting, water may have entered the compressor tray. In this case, do not panic: as the compressor heats up, the water will gradually evaporate. However, if the noise does not stop during the day, you should call a specialist.
Correct startup after defrosting
After you have made sure that the chambers are completely dry, you can start starting. Plug in the refrigerator, but don't load any food yet. Let it run idle for at least 2 hours (for some models up to 4 hours) so that the compressor gains the required pressure and the optimal temperature conditions are established in the chambers.
Check the operation of the thermostat. The refrigerator compartment should become cool and the freezer compartment should become cold. If the equipment is equipped with electronic control, make sure that no error codes are displayed on the display. Models Electrolux or Whirlpool may require a reset or recalibration.
Load products gradually. You should not fill an empty, just defrosted refrigerator with warm food - this will create excess load on the compressor. Place the food in the freezer first, then in the refrigerator compartment. Distribute them evenly without closing the ventilation holes.
⚠️ Attention: If, after turning on, the refrigerator does not begin to cool within 4-5 hours, or the compressor runs continuously without cooling the chambers, immediately turn off the device and contact the service center.
In the first hours of operation, the equipment may produce louder noises sounds (gurgling, clicking) are normal, as the refrigerant circulates through the ice-free pipes. After a few hours, the operating mode will stabilize, and the noise should become a familiar background.
Frequency of defrosting and prevention
How often do you need to defrost a two-chamber refrigerator? For models with manual defrosting or a drip system in the refrigerator compartment, it is recommended to carry out the procedure every 4-6 months, or when the ice layer reaches 5 mm. For systems No Frost one defrosting per year is sufficient for hygienic cleaning, if there are no technical problems.
Regular defrosting not only ensures cleanliness, but also saves energy. The thick layer of ice on the evaporator acts as a heat insulator, causing the compressor to work longer and harder to maintain the set temperature. This leads to increased electricity consumption and wear of parts.
Monitor the condition of the rubber seals on the doors. If they are worn out or dirty, warm, moist air enters the chamber, which accelerates the formation of ice. Wipe the seals every time you defrost and lubricate them with special silicone grease or glycerin to maintain elasticity.
Typical errors during defrosting
One of the most common mistakes is trying to break off the ice with a knife. As already mentioned, this is a direct path to breakdown of the freon tube. Repairs in this case are often unprofitable and comparable to the cost of a new refrigerator. Be patient and use only safe methods.
Another mistake is turning on a wet refrigerator. Water is an excellent conductor of electricity. Trying to start the compressor or electronic board while there is moisture inside may result in a short circuit. Always use paper towels for final drying of corners and seams.
Do not use harsh solvents, acetone or gasoline to remove stickers or dirt from inside the camera. The plastic of modern refrigerators is sensitive to chemicals and may become cloudy or crack. Use only food acids or special products for household appliances.
Is it possible to defrost the refrigerator without completely removing the food?
It is necessary to completely remove the food. If you leave them inside, they will interfere with the circulation of warm air, the melting process will take 3 times longer, and the quality of the products will suffer due to being in a warm, humid environment.
What to do if there is a plastic smell after defrosting?
A slight odor may be associated with heating of the parts during the first start-up. If the smell is strong and chemical, you may have used too hot water or a hair dryer and melted the plastic. In this case, ventilate the chamber for several days. If the smell does not go away, the part needs to be replaced.
Do door hinges need to be lubricated after defrosting?
Yes, this is an excellent preventive measure. While the doors are open and access to the hinges is free, place a couple of drops of machine or special oil on the hinge axis. This will prevent the doors from squeaking and sagging in the future.
How long does it take the refrigerator to gain temperature after defrosting?
The time it takes to reach the mode depends on the volume of the chambers and the power of the compressor. On average, the refrigerator compartment cools down in 2 hours, the freezer in 4-6 hours. Complete stabilization of the temperature inside the food takes up to 24 hours.
Is it possible to wash the refrigerator with soapy water?
It is not recommended to use ordinary laundry or toilet soap, as it leaves a film and odor. It is better to use a solution of baking soda (1 tablespoon per liter of water) or special products for washing refrigerators that do not require thorough rinsing.
