Modern household appliances make life much easier, but even advanced ones systems like No Frost are not without drawbacks, which is why many choose classic models with a crying evaporator. Owners of such equipment sooner or later face the need for scheduled maintenance, as moisture from the products settles on the walls and turns into an ice crust. If you ignore this process, the device begins to hold the temperature worse, and condensation appears on the products.
The ice removal procedure seems trivial, but incorrect actions can lead to damage to the evaporator tubes or failure of the thermostat. It is important to understand the physics of the process: ice on the back wall is the normal operation of the system, but its excess blocks normal air circulation. The critical point is the ban on the use of sharp objects for chipping ice, since a puncture of the freon pipe will lead to expensive repairs.
In this article we will detail Let's look at an algorithm of actions that will help you safely service your Indesit, Atlant or Beko. You will learn how long complete defrosting takes, whether you need to disconnect the device from the network, and how to speed up the process without harming the equipment. Following simple rules will extend the life of the compressor and maintain cooling efficiency.
⚠️ Attention: If you notice that the ice crust is growing unevenly or only on one side, this may indicate a malfunction of the door seal or thermostat, and not the need for defrosting.
Preparation for defrosting procedure
Before starting any manipulations, it is necessary to empty the internal space of the chamber from food. It is better to remove shelves and drawers immediately so that they do not interfere with access to the back wall and do not crack due to temperature changes in the process. If foods are frozen, they should be placed in basins or wrapped in blankets to keep them cold during the procedure.
The next step is to completely disconnect the device from the power supply. Unplug the plug from the socket, but do not pull on the wire itself, so as not to damage the contacts. Some models require a wait before turning on again, so the timer can be started immediately after turning off.
Don't forget to prepare a place to collect melt water. The factory equipment often includes special gutters or trays, but their volume is limited. For large models, it is better to prepare several deep containers and old towels or rags for wiping the floor in advance.
Remove all removable elements: glass shelves, plastic containers, bottle holders and a grill under the freezer. They can be washed separately with warm water and mild detergent. This will allow you to thoroughly clean the hard-to-reach corners of the chamber, which are usually hidden under the drawers.
Natural defrosting: a safe method
The most gentle way to get rid of ice is waiting. Leave the refrigerator and freezer doors wide open. The heat from the room will gradually penetrate inside, starting the process of melting the ice. This method takes the most time, from 6 to 24 hours depending on the thickness of the ice layer and the temperature in the room, but guarantees the safety of all components of the unit.
During the natural melting process, water will flow into the drainage hole located at the bottom of the rear wall of the refrigerator compartment. It is important to ensure that the gutter does not become clogged with crumbs or dirt. If the water remains in the tray and does not drain, carefully clean the channel using a special brush or soft wire wrapped in cloth.
The freezer compartment takes longer to defrost, since the temperature there is lower. If you have a two-chamber appliance, the ice from the refrigerator evaporator will come off faster than from the freezer. Do not try to speed up the process in the freezer with a hairdryer if the instructions for your model LG or Samsung do not specifically allow this, since sudden heating of the plastic can cause its deformation.
Periodically wipe the walls with a dry rag, removing softened ice with gloved hands. This will help reduce the overall procedure time. Make sure that water does not overflow over the edge of the tray onto the floor, especially if you have wood flooring or laminate flooring that is susceptible to moisture.
☑️ Checklist for preparing for defrosting
How to speed up the process without harm to equipment
Sometimes there is no need to wait a day possibilities, and the question arises of how to quickly get the equipment in order. There are several methods that can reduce defrosting time, but they must be used with caution. The main rule is to avoid direct contact of hot objects with the walls of the chamber and glass shelves.
You can use the convection method: place a pan of hot water in the chamber (on a wooden board or towel, but not on plastic!). The steam will settle on the walls and speed up the melting of the ice. There is no need to keep the door closed to ensure the circulation of warm air. Change the water as it cools, but make sure that the pan is not too heavy and hot.
Another option is to use a fan. Direct the flow of room air into the open chamber. This will enhance heat transfer and help the ice melt faster than with natural evaporation. However, this method is effective only if the room is warm enough.
⚠️ Attention: It is strictly forbidden to use open fire, gas burners or hair dryers blowing hot air directly on the plastic to speed up defrosting. This will lead to melting of the internal panels and destruction of the seals.
Some users ask whether it is possible to use a hair dryer at a minimum temperature. Technically, this is possible if you hold the device at a distance of at least 30-40 cm from the surface and constantly move the air flow. However, equipment manufacturers Bosch i Electrolux often do not recommend this method due to the risk of local overheating of the plastic and cracks.
Why can’t you pick ice with a knife?
Aluminum evaporator tubes hidden behind a plastic panel or located directly under it are very thin. One careless blow with the tip of a knife or a screwdriver will pierce the metal, and the freon will instantly evaporate. Repairs in this case will be expensive, since it will require searching for leaks, soldering and refilling with refrigerant.
Washing and disinfection of internal chambers
After all the ice has melted and the water has been collected, the hygienic treatment stage begins. During work, bacteria could multiply inside, an unpleasant odor or mold could appear in hard-to-reach places. The use of aggressive chemicals is unacceptable here, since residues may end up on the food.
The optimal solution would be to prepare a weak solution of baking soda or vinegar. One tablespoon of the substance is enough per liter of warm water. Thoroughly wipe all surfaces: ceiling, side walls, floor and, of course, the back panel. Pay special attention to the rubber seals on the doors, where dirt most often accumulates.
Also rinse removable shelves and drawers in the bath or shower using a soft sponge. Abrasive powders and hard brushes cannot be used; they leave micro-scratches into which dirt then gets clogged. Hot water can deform plastic, so use water at a comfortable temperature.
After wet cleaning, be sure to wipe all surfaces dry with a clean cotton cloth. Residual moisture may turn back into ice when the compressor is first started. Allow the chambers to dry completely, leaving the doors open for another 15-20 minutes.
| Medicum | Proportions | Effect | Features |
|---|---|---|---|
| Food soda | 1 tbsp. l. per 1 liter of water | Odor removal, gentle cleaning | Safe for all surfaces |
| Table vinegar | 1 tbsp. l. per 1 liter of water | Disinfection, removal of plaque | Requires ventilation due to odor |
| Citric acid | 1 tsp. per 0.5 liters of water | Removing greasy stains | Gives a pleasant aroma |
| Ammonia | 1 tbsp. l. for 1 liter of water | Removing complex contaminants | Work only in a ventilated area |
Starting the refrigerator after defrosting
When the chambers are washed and dried, you can begin assembling and starting. Place all shelves, drawers and containers in their proper places. Make sure that they fit tightly and are properly fixed, otherwise the structure may collapse under the weight of the products.
Plug in the device. Immediately after switching on, the compressor may not start working immediately - this is normal, the electronics perform self-diagnosis. Let the empty refrigerator run for at least 1-2 hours until it reaches operating temperature. Only after this can you load products.
You should not fill the chamber to capacity with products during the first hours of operation. A sharp increase in internal temperature can force the compressor to work harder, which will shorten its life. Distribute food evenly without blocking the ventilation holes.
Check the operation of the drainage system. In the first hours after defrosting, water from the previous defrosting may remain in the tray behind the compressor (at the back of the refrigerator), which should evaporate naturally. If a puddle appears under the refrigerator, check whether the device is level - the legs may need to be adjusted.
Typical maintenance errors
Many users make standard mistakes that negate all efforts to care for the equipment. One of the most common is haste. Trying to start the refrigerator without waiting for it to dry completely will lead to the formation of a new ice crust in just a couple of hours.
Using inappropriate cleaning products is the second most popular mistake. Chlorine, acetone or solvents can corrode the plastic, making it brittle and changing color. The smell of chemicals can also be absorbed into food, especially butter and dairy products.
Frequent defrosting “just in case” is also harmful. Drip systems are designed for a specific cycle. If you defrost the unit more than once every 4-6 months, you are simply adding wear and tear to the compressor without any real need. Monitor the thickness of the ice: if it does not prevent the doors from closing and does not cover the food, there is no need to rush.
⚠️ Attention: If, after defrosting and turning on, the refrigerator hums louder than usual or does not freeze for 3-4 hours, air may have entered the system or a leak has occurred. In this case, contact the service center.
Frequently asked questions (FAQ)
How often should you defrost a drip refrigerator?
The optimal frequency is 1-2 times a year. If you notice that the layer of ice on the back wall has become thicker than 5-7 mm, or water has begun to accumulate at the bottom of the chamber, the procedure should be carried out outside the schedule. The frequency depends on the humidity in the room and the number of door openings.
Is it necessary to defrost the freezer compartment together with the refrigerator?
In two-chamber models, it is advisable to do this simultaneously so as not to violate the temperature regime of the entire appliance twice. However, if the freezer has a system No Frost, and the refrigerator has a drip system, then only the refrigerator compartment needs to be defrosted. The freezer is cleaned only when a fur coat forms, which rarely happens.
What to do if the water does not go into the drainage hole?
Most likely, the drain is clogged with food crumbs or mold. Take a special soft brush (often included) or twist a cotton wool band, soak it in warm water and carefully clean the channel. You can also use a rubber bulb to blow out or rinse the hole with water.
Is it possible to defrost a refrigerator on the balcony in winter?
Absolutely not. Taking equipment out into the cold or into an unheated room for defrosting is prohibited. Sudden temperature changes can lead to cracking of plastic, damage to paintwork and disruption of the oil in the compressor. You only need to defrost at room temperature.
Why did an unpleasant odor appear after defrosting?
This may be a consequence of the use of low-quality detergents or food residues that are stuck in hidden cavities. Try wiping the chambers with an activated carbon solution or placing an open pack of soda. If the smell does not go away for several days, professional cleaning of the drainage system may be required.
