After completing the procedure for cleaning the internal space and completely removing the ice crust, the most crucial moment comes, on which the further performance of the entire climate system depends. Many owners of household appliances make the fatal mistake of immediately plugging in the retail cord, believing that once the ice is removed, the unit can be started. However physics of processes dictates different conditions: the compressor and refrigerant must come into equilibrium, and the internal components must be completely dry.
Ignoring the rules for initial startup can lead to water hammer in the system or a short circuit on the electrical contacts, which is especially critical for older models. Atlant. In this article, we will analyze in detail the holding time intervals, sequence of actions and nuances that will help extend the life of your equipment for many years without expensive repairs.
Physical processes inside the cooling system
To understand the need for a pause before turning on, you need to imagine what is happening inside the circuit during defrosting. During the thawing process, ice turns into water, which actively evaporates, increasing the humidity inside the chambers and in the technical compartment. At the same time, refrigerantcirculating through the tubes changes its state of aggregation and pressure.
If you turn on the compressor immediately, the oil, which should lubricate the rubbing parts, can be in a gaseous state or mixed with liquid freon. This leads to the engine operating in oil starvation mode. In addition, residual moisture on the evaporator can instantly freeze during a sudden start, creating a plug that is difficult to remove without vacuuming.
⚠️ Attention: An attempt to start a wet unit is fraught with breakdown of the insulation on the starting relay. Water is a conductor, and even a microscopic drop on the contacts can cause sparking and failure of the electrical control circuit.
It is also important to consider the condition thermostat. During defrosting, its sensors cool unevenly and require time to return to room temperature in order to correctly read readings at the time of start. A sudden start can throw off the calibration, and the refrigerator will operate in the wrong mode.
Exposure time: how long to wait
The most common question asked to service center masters: how long exactly should it stand Atlant turned off condition? The answer depends on the duration of defrosting and the room temperature. There is a golden rule: the downtime should be no less than the time that the unit was defrosted, but with a mandatory minimum threshold.
For a standard situation, when defrosting took about 4-5 hours, the minimum holding time before turning on is 2-3 hours. This time is enough for most of the moisture to evaporate from the electrical contacts and for the compressor to warm up to room temperature. If you defrosted the device for a day or used a hairdryer to speed up the process, the waiting time increases to 6-8 hours.
Particular attention should be paid to models with the system No Frostalthough they require defrosting less often. They have many hidden cavities where water can be retained. If you start a fan with water inside, this can lead to icing of the blades and jamming of the motor.
Ambient temperature also plays a role. If the room is cold (less than +15°C), the process of moisture evaporation is slower and the compressor oil becomes more viscous. In such conditions, the pause should be increased by 1-2 hours beyond the norm.
Step-by-step algorithm for first switching on
The startup process must take place strictly according to a specific scenario in order to minimize stress on the equipment. First, you need to visually check that all surfaces, including rubber door seals and shelves, are completely dry. Wipe them with a soft cloth if any drops remain.
Next, you should check the position of the refrigerator itself. It must stand strictly horizontally, which is checked by the building level. Misalignment can disrupt the oil circulation in the compressor Atlant, which will lead to increased noise and wear of parts.
☑️ Checklist before turning on
Only after completing the preparatory steps can you connect the power cord to the outlet. Please note that the outlet must be grounded and correspond to the power characteristics of the device. Do not use extension cords and tees the first time you turn it on after a period of inactivity.
After connecting to the network, you will hear a characteristic click - this means the starting relay has activated. After a few seconds the compressor should start working. If there is no sound, but the light inside is on, perhaps the thermostat has not yet warmed up or the protection has tripped.
Table of holding time intervals
For ease of perception of information about how long the unit should stand, we have systematized the data in a table. These recommendations are relevant for most brand models Atlant, including double-chamber and single-chamber options.
| Defrost situation | Minimum waiting time | Optimal waiting time | Risk in case of violation |
|---|---|---|---|
| Scheduled defrosting (4-5 hours) | 2 hours | 4 hours | Average (malfunctions) |
| Emergency defrosting (more than 12 hours) | 6 hours | 12 hours | High (compressor failure) |
| Use of hair dryer/steam | 4 hours | 8 hours | High (short circuit) |
| Moving (transportation lying down) | 8 hours | 24 hours | Critical (oil blow) |
Pay attention to the last point of the table. If the refrigerator was transported in a horizontal position before defrosting, the waiting time increases significantly. The oil needs time to drain back into the compressor crankcase from the pipe system.
⚠️ Attention: If you used chemicals for cleaning or defrosting, the holding time should be increased. Chemical vapors must completely evaporate so as not to damage plastic parts and rubber seals when heated.
Operation control after startup
After you have turned on the device, you cannot simply leave it unattended. The first 30-40 minutes of work are diagnostic. At this time compressor it gains momentum, and the system enters operating mode. Listen to the sound of the motor: it should be smooth, monotonous, without knocking, gurgling or sharp vibrations.
Check the heating of the condenser grid (usually it is located on the back or sides of the housing). After 15-20 minutes of operation it should become warm or hot. If the grate is cold and the compressor is humming, there may be a freon leak or a blockage in the capillary tube.
What to do if the compressor does not start?
If, after being plugged in, the compressor is silent, but the light is on inside, try gently turning the thermostat knob. If this does not help, the starting relay may have burned out or the motor itself has failed. In this case, you need to call a specialist. Do not try to disassemble the electrical part yourself unless you have the appropriate qualifications.
You should also pay attention to the formation of cold. After an hour of operation, light frost should appear inside the chambers (in the drip system) or the temperature should drop (in No Frost). If after 2 hours of operation it is warm inside, it means that the cooling cycle has not started.
Loading with products and entering the mode
One of the main mistakes is instantly loading the refrigerator with food immediately after turning it on. Thermal load the pressure on a newly started compressor will be enormous, which can lead to its overheating and protection shutdown. The refrigerator Atlant must first reach the specified temperature when empty.
Usually this process takes from 4 to 8 hours, depending on the volume of the chambers and the temperature in the room. Only after the unit turns off itself (or goes into temperature maintenance mode) can you start adding food. This should be done gradually, in small portions.
Do not load warm food. This will upset the temperature balance and cause the system to wear out. All products must be cooled to room temperature before being placed inside.
Common mistakes and their consequences
Even knowing the theory, users often make practical mistakes. For example, many people try to speed up drying by directing a hot stream of air from a hair dryer at maximum power inside. This can deform the thin plastic of the inner box and damage the sensors.
Another common mistake is connecting to the network through an unstable power source. Voltage surges when the compressor starts are especially dangerous. Use a surge protector or stabilizer if the light in your network often “jumps.”
⚠️ Attention: Never turn on the refrigerator if you notice traces of oil under the compressor or smell a burning smell. These are signs of a serious problem that requires professional diagnosis before restarting.
Ignoring the instructions for leveling the legs will result in the door not fitting tightly. As a result, the cold disappears, the compressor works without interruption, trying to compensate for the losses, and quickly burns out. Regularly check the tightness of the seal.
Questions and answers (FAQ)
Is it possible to turn on the Atlant refrigerator 1 hour after defrosting?
It is highly not recommended. An hour is not enough to completely evaporate moisture from hard-to-reach places and stabilize freon pressure. There is a high probability of a short circuit or water hammer in the compressor.
Why does the refrigerator hum more than usual after turning on?
In the first hours of operation after defrosting, an increased hum is possible due to uneven distribution of the refrigerant or residual vibration. If the noise does not subside after a day, check the distance to the walls and the installation level.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, after defrosting, be sure to wipe the internal surfaces with a dry, clean cloth to remove any remaining condensation. A humid environment promotes the growth of bacteria and the formation of mold.
What to do if the light does not light up after turning it on?
Check whether the door is tightly closed (in some models the light goes out when opened, but the sensor may stick). Also check the integrity of the socket and the lamp itself. If the problem is electrical, the part will need to be replaced.
How long does it take for the refrigerator to reach temperature after being idle?
It usually takes 2 to 4 hours to reach operating temperature in an empty refrigerator. Complete stabilization of the temperature regime throughout the entire volume takes up to 8-10 hours.
