After completing the defrosting procedure, when the ice crust has completely disappeared and the interior of the chamber has been thoroughly washed, the owner is faced with an important question about the correct start-up of the equipment. Errors at this stage can negate all care efforts or even lead to breakdown of an expensive compressor, so haste is unacceptable here. Atlant refrigerator, like any other equipment of this class, requires compliance with certain time intervals and sequence of actions to reach operating mode.
Many users forget about physics of processes occurring inside the system, and try to start the unit immediately after wiping the shelves. This is a serious mistake that can be fatal for motor-compressor. In this article, we will analyze in detail why it is necessary to wait time, how to check the condition of the equipment before turning it on, and what signals may indicate a malfunction.
Compliance with the starting technology guarantees a long and trouble-free service of your household appliance. We will look at the nuances for different models, including two-chamber systems and units with the No Frost system, where the process may have its own characteristics. Carefully study the recommendations to avoid common mistakes.
Why you can’t turn on the refrigerator right away
The main reason for the need for a pause lies in the properties of the refrigerant and oil circulating in the system. During operation of the compressor, the oil partially enters the evaporator and condenser circuits, and during defrosting, when the equipment is turned off, it flows to the lower part of the system, often collecting in the compressor or pipes.
If you start motor-compressor immediately, the oil will not have time to return to the crankcase, which will lead to “dry” operation. This causes critical wear of the rubbing parts and can cause the piston group to jam. In addition, a sharp start creates excess pressure in the system, which an unprotected mechanism cannot cope with.
⚠️ Attention: An attempt to turn on the unit with residual moisture in the electrical circuits or with oil in the evaporator can lead to a short circuit or water hammer in the cooling system.
It is also important to consider the condition of the electrical contacts. Even if visually everything seems dry, microscopic drops of condensation may remain on the terminals of the thermostat or start relay. Turning on the wet contacts under voltage will lead to oxidation and eventual burnout of the control elements.
What happens if you ignore the waiting time?
If you turn on the refrigerator ahead of time, the compressor may start working with increased noise, humming, or may not start at all, going into protection. In the worst case, the high-pressure pipes will rupture or the motor winding will burn out, which will require expensive repairs with the replacement of components.
How long to wait before starting
Waiting time is not an abstract concept, but a technically sound parameter that depends on the duration of defrosting and the room temperature. The standard rule is: the rest time should be no less than the time the refrigerator was turned off, but within reasonable limits.
For most models Atlant the minimum waiting period is 2 hours. This time is necessary for the refrigerant to completely transform into a liquid state and distribute throughout the system, and for the oil to flow back into the compressor. If defrosting lasted a long time (more than 12 hours), it is better to increase the pause to 4 hours.
The temperature in the room also plays a role. In a cold room, the oil becomes more viscous and flows more slowly. In a hot room, on the contrary, processes go faster, but the risk of overheating at startup is higher. The optimal room temperature is considered to be from +18 to +25 degrees Celsius.
You shouldn’t rely on traditional methods like “knock on the compressor” or “shake the unit.” These actions will not speed up the drainage of oil, but may damage the fasteners or tubes. Patience is the only reliable assistant in this process.
Checking the technical condition before turning on
Before inserting the plug into the outlet, it is necessary to conduct a visual and tactile inspection of the equipment. Make sure there are no puddles of water inside the chambers, especially in the rear compressor well. Moisture in this area can cause corrosion or short circuiting.
Check the integrity of the rubber seals on the doors. After defrosting and washing, they may have shifted or become deformed. Seal Must fit tightly to the housing around the entire perimeter, otherwise the cold will escape, forcing the compressor to work without interruption.
Inspect the rear grille of the condenser. Sometimes when cleaning, users accidentally bend thin slats or damage the tubes. Any mechanical damage must be repaired before starting. Also check that the shelves and drawers are securely fastened - vibration during startup can move poorly installed elements.
☑️ Ready to start
Pay special attention to the electrical cable. It should not have cracks, creases or signs of rodents. If you use an extension cord or surge protector, make sure that they are rated for the appropriate power.
Step-by-step startup instructions
The startup process should be smooth and controlled. First make sure the temperature control is set to the middle position. For most models Atlant this is division “3” or “4” on a mechanical thermostat, or “Eco” mode on electronic panels.
Insert the plug into the socket. You should hear the characteristic click of the start relay and the hum of the compressor starting. If a loud crack is heard, the hum stops abruptly, or the sound of an “iron clang” is heard, immediately unplug the device. These are signs of a malfunction of the starting device or the compressor itself.
After a successful start, do not rush to load the products. Let the refrigerator run idle for at least 1-2 hours. During this time, it will reach the required temperature, and the thermostat will turn off the compressor. This will be a signal that the system is functioning correctly.
| Stage | Action | Expected result |
|---|---|---|
| 1. Preparation | Setting the regulator to the middle position | Indicators are on, the panel is active |
| 2. Start | Connecting to the network | Relay click, smooth motor hum |
| 3. Check | Operation control 15 minutes | Absence of extraneous noise, vibrations |
| 4. Waiting | Work without load for 2 hours | The compressor turns off itself |
If your model is equipped with electronic control, wait until the self-diagnosis is completed. Error codes may appear on the display if the system detects door leaks or other problems. In this case, refer to the instructions to decipher the code.
First filling with food
You can load food only after the refrigerator has returned to normal mode. If you put warm food or a large amount of food in a warm drawer, the compressor will work hard trying to cool the volume, which can cause it to overheat.
Start with small portions. Lay out the products evenly, without pressing them close to the back wall where the evaporator is located. Air circulation should be free, especially in models with a system No Frost, where fans drive air through special channels.
⚠️ Attention: It is strictly forbidden to load products whose temperature exceeds room temperature into the chamber. This will place extreme stress on the system and can cause ice build-up even in modern models.
Pay attention to the weight of the products. Shelves made of tempered glass can withstand a certain load, but during the first start-up, when the structure is still “grinding in” after defrosting, it is better not to overload them immediately. Distribute the weight evenly.
Typical mistakes and troubleshooting
One of the most common mistakes is ignoring the installation level. If, after defrosting and washing the floors, the refrigerator has been moved and is standing crookedly, the compressor may operate with increased noise. Use a building level and adjustable legs for leveling.
Another problem is “airing” of the system if defrosting was carried out in violation of technology (for example, chipping ice with sharp objects). In this case, the refrigerator may hum, but not cool. You need to call a technician for vacuuming and refilling.
If you notice that after turning on the refrigerator works without interruption for more than 3-4 hours, check:
- ❄️ Are the doors closed tightly and is there anything preventing them from closing.
- 🌡️ Is the temperature set correctly? (not to the maximum).
- 🔌 Is there enough voltage in the network (low voltage prevents starting).
- 🧊 Is the unit loaded with a large volume of warm products.
Continuous operation of the compressor is dangerous due to its overheating. If after 5-6 hours the mode has not returned to normal (the compressor has not turned off), you need to turn off the device and contact the service center.
Frequently asked questions (FAQ)
Is it possible to turn on the Atlant refrigerator 30 minutes after defrosting?
It is strictly not recommended. 30 minutes is not enough for the oil to drain into the compressor and evaporate the moisture. The minimum safe period is 2 hours.
What to do if, after turning on, the refrigerator hums, but does not freeze?
There may have been a water hammer or a freon leak due to early start-up. Turn off the device and call a technician. You cannot open the system yourself.
Do you need to wash the inside of the refrigerator before turning it on for the first time?
Yes, definitely. After defrosting, condensation and possible dust remain inside. Wipe the chambers with a dry soft cloth before starting.
Why did an unpleasant odor appear after defrosting?
It could be the smell of stagnant water in the drainage or food residues. Wash the drainage hole with a soda solution and ventilate the chambers before turning them on.
How long does it take for the refrigerator to gain temperature after defrosting?
Usually the process of reaching the mode takes from 2 to 6 hours, depending on the volume of the chambers, the room temperature and the compressor model.
