Single-chamber models of refrigeration equipment brands Atlant are deservedly popular due to their reliability and simplicity of design. However, like any equipment operating on the principle of a drip system or with manual defrost control, these devices require periodic user intervention. Many owners ignore the need for regular maintenance, which leads to the formation of a thick ice crust on the evaporator and reduced operating efficiency.
The process of clearing the chambers of ice cannot be rushed and requires adherence to a clear algorithm of actions. Improper defrosting may cause failure thermostat or damage to the internal coating. In this article we will analyze in detail all the stages of preparing, carrying out and completing the procedure for models with one compressor and one chamber.
It is worth immediately noting that the frequency of the procedure directly depends on the operating conditions and humidity in the room. If you notice that a layer of frost has become visually noticeable or the door has begun to close worse, then it’s time to act. Ignoring these signs leads to increased energy consumption.
Preparing the refrigerator for defrosting
The first and most important step is to completely disconnect the unit from the electrical network. To do this, unplug the power cord from the outlet. You should not rely only on the power button, if it is provided by the design, since electronics it must be completely de-energized for the safety of work. After disconnecting, remove all products, shelves and drawers.
Pay special attention to the safety of products during the procedure. If it’s winter outside, you can take perishable goods out to the balcony after pre-packing them. In the summer, you will have to use thermal bags or fill existing containers with cold water to create a buffer zone. All removable interior elements, such as glass shelves and plastic trays, should be removed and set aside.
⚠️ Attention: It is strictly forbidden to try to remove shelves or drawers if they are frozen to the walls. Allow the ice to melt a little naturally, otherwise you risk breaking the mounting guides or breaking the glass.
To collect melt water, prepare flat containers with low sides and absorbent rags. Place towels on the floor in front of the refrigerator, as water can leak not only into the tray, but also out if the drain hole is clogged or overfilled. Prepare a soft sponge and the cleaning product you plan to use in advance.
Natural defrosting versus accelerated methods
There are two main approaches to removing ice: natural and forced. Plant engineers Atlant recommend using exclusively natural methods. It consists in the fact that after turning off the equipment, you simply leave the doors open and wait for the ice to melt under the influence of room temperature. This process can take from 3 to 10 hours depending on the thickness of the ice layer.
Accelerated methods, such as using hair dryers, fan heaters or containers of boiling water, carry serious risks. A sharp temperature change can lead to microcracks in the plastic housing of the evaporator or damage the sealing rubber of the door. In addition, the contact of hot water with cold tubes causes stress on the metal, which shortens the life of the heat exchanger. sealing rubber doors. In addition, hot water entering cold tubes causes stress on the metal, which shortens the life of the heat exchanger.
If you still decide to use a hair dryer to speed up the process, keep it at least 30-40 cm from the surface and constantly move it. Direct the air flow evenly, without stopping at one point. However, remember that even careful use of electrical appliances inside a wet chamber can be dangerous.
Why can’t you pick ice with a knife?
Using sharp objects (knives, screwdrivers, scrapers) to chip ice is the most common reason for refrigerators to fail. In single-chamber models, the evaporator is often located directly behind the rear wall of the chamber. One awkward movement can puncture a thin-walled refrigerant tube. Repair in this case requires calling a technician, filling with freon and replacing the compressor, which is not economically feasible.
Procedure for removing ice
After the main body of ice has softened and began to peel off from the walls, you can begin to carefully remove water. Use a ladle or rubber bulb to pump out liquid from the bottom pan. If the water has frozen in the drainage channel, clean it using a special flexible brush or soft wire pre-wrapped with cloth.
Wipe off any remaining moisture thoroughly with a dry, clean rag. Pay special attention to the corners of the chamber and the space under the freezer compartment (if it is in the form of a box). It is important that there are no puddles left inside, since when turned on they can quickly turn into an ice crust that interferes with air circulation.
☑️ Checklist for preparing for washing
Check the condition while removing ice door seal. If there are pieces of ice left on the rubber, carefully remove them with your fingers. Ice on the seal disrupts the tightness of the closure, which will lead to constant freezing of the fur coat in the future. Make sure that the rubber cuff is clean and elastic.
Washing and disinfection of internal surfaces
After complete removal of ice and water, the sanitization stage begins. To clean the inner walls of the chamber, it is best to use a weak solution of baking soda or a special household appliance product without abrasive particles. Aggressive chemicals can damage the plastic coating and leave an unpleasant odor, which is subsequently absorbed into the products.
Wipe all surfaces with a damp sponge, paying attention to the places where the shelves are attached and the handles. Don't forget to rinse the shelves and drawers in the bathroom under running water. After washing, be sure to wipe all elements dry to prevent the formation of condensation immediately after switching on.
| Element | What to wash | What to wipe | Features |
|---|---|---|---|
| Plastic walls | Soda solution | Dry microfiber | Do not rub with the hard side of the sponge |
| Glass shelves | Glass cleaner | Paper towel | Allow to dry completely before installation |
| Sealant | Warm water | Dry cloth | Check for wrinkles mold |
| Rear grille | Vacuum cleaner or brush | Dry brush | Clean from dust for better heat transfer |
It is especially worth mentioning cleaning outer surface. Metal sides and doors can be wiped down with polish to remove fingerprints and grease stains. This will not only improve the appearance, but will also create a protective film that repels dust.
Correct startup after defrosting
When the chamber is washed and wiped dry, do not rush to immediately load the products. Reassemble the structure in reverse order: install shelves, drawers and fasteners. Make sure that all elements fit into place smoothly and are not skewed. The door should close tightly and with a characteristic clap.
Plug in the refrigerator. For models Atlant with mechanical thermostat control, it is recommended to first set the regulator knob to the minimum power position (usually number 1). Let the unit run idle for about 2-3 hours. This will allow the compressor to enter operating mode and cool the chambers without unnecessary load.
⚠️ Attention: It is prohibited to load warm foods or large amounts of food immediately after switching on. This will cause a temperature spike and cause the compressor to work harder trying to compensate for the heat.
After the refrigerator reaches temperature (usually it takes 4-6 hours for a full cycle), you can carefully load the food. Place those that require deep freezing or quick cooling first. Distribute supplies evenly across shelves without blocking ventilation openings.
Typical maintenance errors
One of the most common mistakes is ignoring the drain hole. In single-compartment refrigerators, condensation often flows into a groove, from where it must leave through the drain. If this channel is clogged with crumbs or slime, water will accumulate at the bottom of the chamber and, when frozen, will turn into an ice block that is difficult to remove.
Another mistake is using the wrong detergents. Chlorine solutions or powders with large abrasive particles can scratch the plastic. Over time, dirt accumulates in these scratches and bacteria multiply, which are then very difficult to get rid of. In addition, aggressive chemicals can corrode the plastic, making it brittle.
Also, users often forget about the outside back wall. There is a condenser grill (radiator) located there. If it is covered with a layer of dust and pet hair, heat transfer deteriorates. The compressor is forced to work longer and harder, which leads to its overheating and premature wear.
Frequently asked questions (FAQ)
How How often do you need to defrost a single-chamber Atlant?
The frequency depends on the model. If this is a No Frost system, then defrosting is required only for sanitary treatment once a year. If a drip system or manual defrosting - as an ice crust 3-5 mm thick forms, usually once every 3-6 months.
Is it possible to defrost a refrigerator without unplugging it?
No, this is dangerous for the life and health of the equipment. Water is a conductor of electricity, and its contact with contacts or electronic modules when the power is on is guaranteed to lead to a short circuit and breakdown.
What to do if the refrigerator does not turn on after defrosting?
Check whether the door is tightly closed and whether the thermostat is installed correctly. If after 2-3 hours of operation there is no sound from the motor, the contacts may have oxidized or the protection has tripped. Diagnostics by a specialist is required.
Why did an unpleasant smell appear after defrosting?
Most likely, particles of old food remained inside or water got into hard-to-reach places and stagnated. It is necessary to re-wash the chamber with a solution of vinegar or citric acid and ventilate it with the door open for 24 hours.
