Proper start-up of household refrigeration equipment after defrosting is not just a matter of convenience, but a critical procedure on which the durability of the compressor and the quality of operation of the entire system directly depend. The owner of Belarusian-made equipment Atlant often encounters a situation where, after removing ice and washing the chambers, the unit refuses to freeze or makes unusual sounds. This occurs due to a disruption in the physical processes of circulation of refrigerant and oil in the circuit.
Ignoring the rules for initial start-up can lead to water hammer in the compressor, failure of the start relay, or a banal lack of cold during the day. In this article we will analyze in detail why it is necessary to observe time intervals, how to check the tightness of the system and what actions to take if the equipment does not start. Compliance with the algorithm will avoid costly repairs and keep food fresh.
Modern two-chamber models Atlant equipped with reliable, but sensitive to operating conditions motors. Before pressing the power button, it is important to make sure that all internal components are completely dry, and the temperature in the room corresponds to the technical data sheet of the product. It is critical to wait 2 to 4 hours after defrosting before connecting to the network, so that the oil drains into the compressor crankcase. Next we will look at each stage of preparation in detail.
Why you can’t turn on the refrigerator right away
The main reason for the ban on instant start lies in the design of the compressor and the properties of the refrigerant. During operation of the refrigerator, oil circulates through the system along with freon, partially settling in the evaporator and condenser. During defrosting, when the unit is turned off for a long time, the oil flows back into the compressor under the influence of gravity, but this process takes time.
If you turn on the engine while the oil is still in the heat exchangers or has not completely returned to the crankcase, the effect of “oil starvation” may occur. The moving parts of the mechanism will begin to run dry, which will lead to rapid wear and jamming. In addition, a sharp start with cold oil of high viscosity creates an excessive load on the electrical winding.
Another factor is condensation. After washing the chambers and defrosting, moisture may remain on the internal walls, rubber seals and, most dangerously, on the electrical contacts. Water entering the terminals of the thermostat or start relay will cause a short circuit or oxidation of the contacts.
⚠️ Attention: Attempting to start the compressor with water in the drainage system or on the contacts can lead to irreversible damage to the electronics and requires professional diagnostics.
It is also worth considering the temperature difference. If you washed the refrigerator with warm water and then immediately turned it on, the sudden cooling of the plastic elements and tubes can cause microcracks. The materials should take room temperature naturally.
Preparing for the first start: checking the condition
Before looking for an outlet, it is necessary to conduct a thorough visual and tactile diagnosis of the internal space. Make sure that the chambers are completely free of water. Pay special attention to the recesses in the lower part of the refrigerator compartment and the condensate drainage channel above the door.
Check the condition of the sealing rubber bands. After defrosting, they should be clean, elastic and fit snugly to the body. If the rubber is dry or deformed, the seal will be compromised and the compressor will run idle, trying to gain temperature.
Inspect the back wall of the refrigerator (condenser grill) for mechanical damage. When washing the chambers, a careless movement can touch the evaporator tubes, especially in models with a system No Frost or a weeping evaporator hidden behind the panel.
Make sure that the refrigerator is installed level. Use a building level or just rock the body. Uneven installation will lead to vibrations, noise and improper operation of the doors, which will affect energy consumption.
List of necessary actions before turning on:
- 🧼 Completely wipe all surfaces dry with a clean rag.
- 🔌 Inspect the power cord for kinks and damage insulation.
- 🧊 Make sure that shelves and drawers are in place and do not block air flow.
- 🌡️ Check that the room temperature is not lower than +10°C and not higher than +32°C.
Time intervals: how long to wait after defrosting
Waiting time is the most important parameter during operation. For different models Atlant and different situations, the duration of the pause may vary. The standard recommendation from manufacturers states that the minimum settling time is 2 hours.
However, if defrosting was carried out using hot water or a hairdryer (which is not recommended, but sometimes happens in emergency cases), the waiting time increases to 4-6 hours. This is necessary to completely equalize the temperature of all units of the unit to room temperature.
The table below shows approximate time intervals depending on the situation:
| Situation | Minimum waiting time | Recommended time |
|---|---|---|
| Scheduled defrosting (without water) | 30 minutes | 2 hours |
| Washing chambers with water | 2 hours | 4 hours |
| Transportation on the side | 4 hours | 8-12 hours |
| Sharp change in room temperature | 2 hours | 4 hours |
Why Is it better to wait than to hurry? The compressor is the heart of the refrigerator and is expensive to replace. An extra hour of downtime will not harm the food if you plan to load it later, but an early start can kill the motor.
Step-by-step instructions for turning on refrigerator Atlant
The startup process should take place consistently and without haste. First make sure the temperature control (thermostat) is in the "0" or "Off" position. This will prevent an immediate load on the system when voltage is applied.
Insert the plug into the outlet. Make sure the outlet is grounded and meets the wattage requirements (usually a standard 16A household outlet is sufficient). Do not use extension cords and tees, as they can cause heating of the contacts and a fire.
After connecting to the network, turn the thermostat knob to the operating position. For two-chamber models Atlant the optimal starting value is position “2” or “3” (middle mode). Do not immediately turn the regulator to maximum.
Listen to the operation of the unit. A few seconds after turning the knob, you should hear a click from the start relay and the characteristic hum of a running compressor. If you hear only a quiet hum or clicks, and the motor does not start, immediately turn off the device.
Algorithm of actions when starting:
- 🔌 Make sure that the thermostat is turned off.
- ⚡ Connect the power cord to a working outlet.
- 🎛️ Set the temperature regulator to the average value.
- 👂 Listen to the compressor start for 1-2 minutes.
☑️ Checklist before loading products
First hours of operation: normal sounds and behavior
After successful startup, the refrigerator enters active cooling mode. In the first 30-60 minutes of operation, the unit may be noisier than usual. This is due to the fact that the system is pumping refrigerant, and sounds of fluid flowing, gurgling or hissing may occur in the pipes.
Two-chamber models with one compressor are characterized by alternating cooling of the chambers. You can hear the motor slow down and then speed up again. This is a normal cycle, controlled electronically or by a mechanical timer.
The temperature in the refrigerator compartment will begin to decrease gradually. Full achievement of the specified parameters (+4...+5°C) takes from 2 to 6 hours, depending on the ambient temperature in the room and the volume of the chambers. The freezer will take longer to reach sub-zero temperatures.
Do not load food right away! An empty refrigerator will reach temperature faster and more efficiently. Warm products will create an excessive thermal load, causing the compressor to work hard in the first hours.
⚠️ Attention: If during the first 2 hours of operation the side walls of the refrigerator (where the condenser is hidden) remain cold, but the inside does not get colder, there may be a freon leak or a clogged capillary tube.
Why Is a new or defrosted refrigerator humming?
The hum may increase due to resonance with the floor surface or proximity to furniture. Check that the refrigerator is not touching a wall or cabinet. Also, humming may be a sign of a high-power compressor, which is normal for large Atlant models.
Typical errors and troubleshooting
Even if all the rules are followed, nuances may arise. Often, users forget to remove the shipping bolts (if they were installed upon delivery), but after defrosting, the main mistake is trying to speed up the cooling process.
Do not open the doors often during the first hours of operation. Every time you open the door, you let in warm, humid air, which condenses on the evaporator and prevents the temperature from rising. This also leads to the formation of excess ice.
If the refrigerator Atlant after defrosting turned on, worked for 5-10 minutes and turned off, but it’s warm inside, check the thermostat. It may have remained in the "minimum" position or failed. Also, the cause may be a faulty start relay.
Common problems and their causes:
- ❄️ No cold: freon leak, compressor or thermostat faulty.
- 💧 Water is flowing: The drainage channel is clogged or the condensate collection container is not installed correctly.
- 🔊 A loud knock: The refrigerator is not level or the compressor is damaged.
- 💡 The lamp is on, but there is silence: The motor or starter is burned out relay.
When you can load products
Loading products is the final stage. This can only be done after the refrigerator is in operating mode. This can be determined by a thermometer placed inside or by the indication (if there is a display).
The optimal time for the first boot is 6-8 hours after switching on. By this time, the freezer should freeze the water in the ice trays, and a stable cold background will be established in the main chamber.
Load the food gradually. Do not fill the volume more than half on the first day. A sharp increase in temperature inside the chambers will cause the compressor to work in overload mode, which will shorten its life.
Distribute food evenly without blocking the ventilation openings (in models No Frost) and without pressing food against the back wall (in models with a drip system) to avoid freezing.
What to do if the Atlas refrigerator hums after defrosting?
The hum can be caused by several reasons. First, check the installation: the refrigerator should be level, with all four legs touching the floor. Secondly, make sure that the unit does not touch walls or furniture. If the compressor itself is humming (a loud, low-frequency hum), this may be a sign of wear or water hammer if you were too quick to turn it on. In this case, you need to call a specialist.
Is it possible to turn on the refrigerator if there is water left inside?
It is strictly not recommended. Water can get into the electrical contacts of a thermostat, light bulb, or start relay, causing a short circuit. In addition, when the water in the drainage hole freezes, it forms an ice plug, which will interfere with condensate drainage in the future. Thoroughly wipe all surfaces with a dry cloth before turning on.
How long does the Atlant refrigerator take to reach the temperature after turning on?
For two-chamber models of medium volume (250-350 liters), primary cooling to +5°C in the refrigerator compartment takes about 2-3 hours. The freezer reaches -18°C in 4-6 hours. Complete stabilization of the temperature of the loaded products occurs within 12-24 hours.
Is it necessary to lubricate the seals after defrosting?
Yes, this is a useful procedure. Rubber seals may dry out after contact with water and detergents. Wiping them with a weak solution of glycerin or a special silicone grease will extend the life of the rubber, maintain elasticity and ensure a tight fit of the door.
