Buying a new refrigerator is always a joyful event, marking an update of household appliances and increased comfort in the kitchen. However, the euphoria of acquisition often clashes with the harsh reality of physical processes that require patience. Immediately after delivery of the unit to the apartment, a reasonable question arises: is it possible to plug the plug into the socket immediately or is it better to wait?
The answer to this question is not as clear as it might seem at first glance, and depends on many factors, including the temperature outside, the method of transportation and the type of refrigerant. Errors at this stage can lead to serious damage to the compressor, the replacement cost of which sometimes reaches half the price of a new device. Therefore, it is extremely important to understand the nuances of operation before the first start.
In this article we will analyze in detail why settlement time is a critical parameter, how the position of the refrigerator during transportation affects its further operation, and what will happen if you ignore the manufacturers’ recommendations. You will learn how the requirements differ for different models and how to properly prepare the equipment for the first turn on, so that it will serve for many years without complaints.
Why you can’t turn on the refrigerator immediately after delivery
The main reason for the ban on instant start-up lies in the design of the compressor, which is the heart of the refrigeration system. In the compressor crankcase there is a special compressor oilnecessary for lubricating rubbing parts and removing heat. During transportation, especially if the refrigerator was tilted or shaken, this oil could move from the crankcase to the circuits of the cooling system, in particular to the condenser or evaporator.
If you turn on the unit immediately, the compressor will start to run dry, which will lead to rapid wear of the piston group and jamming of the mechanism. In addition, the oil that gets into the system creates a plug that prevents the circulation of the refrigerant, due to which the discharge pressure increases sharply and the cooling efficiency drops to zero. Inverter compressors in this regard, they are even more sensitive to the lack of lubrication than classic models.
⚠️ Attention: An attempt to start a refrigerator with oil in the cooling circuit can lead to water hammer, which will physically destroy the compressor valves. Repair in this case is often not economically feasible.
Another important factor is condensation. When you bring a refrigerator from the cold (for example, from the street or an unheated warehouse) into a warm room, moisture forms on the internal elements and, most dangerously, on the electrical contacts. Instantly turning on such a device is fraught with a short circuit and failure of the control board or start relay.
Dependence of the waiting time on the position during transportation
The time you need to wait before starting it for the first time directly depends on the position in which the refrigerator was transported to your apartment. This is a key parameter that determines the rate at which oil flows back into the compressor crankcase. Manufacturers usually indicate this data in the instructions, but there are general technical standards that are relevant for most brands, such as LG, Bosch, Samsung and others.
If the unit was transported in a strictly vertical position, the risk of oil getting into the system is minimal. In this case, it is enough to simply let the device stand to equalize the temperatures and calm the refrigerant. However, in practice, achieving perfect verticality in the back of a truck or an elevator is almost impossible, so even in this case, a short-term standstill is required.
A much more difficult situation arises if the refrigerator was transported lying on its side or at a strong inclination (more than 40 degrees). In this position, oil is guaranteed to flow into the evaporator tubes. For it to glass back, it takes a significant amount of time, depending on the viscosity of the oil and the ambient temperature.
| Transport position | Recommended standing time (summer) | Recommended standing time (winter) | Risk of contact oil |
|---|---|---|---|
| Vertical | 2–4 hours | 4–6 hours (including warming up) | Low |
| At an angle of up to 40° | 4–8 hours | 8–12 hours | Average |
| Lying on side | 8–12 hours | 12–24 hours | High |
| Lying on the back | 12–24 hours | 24 hours or more | Critical |
The influence of ambient temperature on the first start
Temperature plays a dual role: it affects both the viscosity of the oil and the formation of condensation. In the summer, when the room is warm, the oil becomes more liquid and drains faster, but the risk of the compressor overheating when first started is higher due to the high air temperature around the condenser.
In winter, the situation becomes more complicated. Cold oil thickens and drains more slowly, requiring longer settling times. But the main danger of winter delivery is condensation. Moisture formed inside electronic components due to sudden temperature changes can cause contact corrosion or short circuiting. Therefore acclimatization techniques in winter are mandatory.
There is a common misconception that in winter the refrigerator can be turned on immediately, since it is already cold. This is a dangerous mistake. The refrigerator must be operated in a warm room so that the refrigerant circulates correctly between the phases. Starting a frozen unit can lead to incorrect operation of the thermostat and sensors.
⚠️ Attention: It is strictly forbidden to turn on the refrigerator if it has just been brought in from the cold. Let it stand turned off for at least 4-6 hours so that the condensation evaporates and the oil warms up.
What to do if the refrigerator needs to be turned on urgently?
If the situation is hopeless and the refrigerator was transported vertically in the warm season, the minimum waiting time can be reduced to 2 hours. However, this is always a risk, and the manufacturer declines responsibility for damage if the instructions are ignored.
Specifics of launching different types of refrigerators
The modern market offers many modifications of refrigeration equipment, and each of them has its own characteristics. Classic single-compressor models are quite simple and forgive some installation errors. Their dwell time is standard and rarely exceeds 8 hours even under unfavorable transportation conditions.
Two-compressor systems, where one motor serves the freezer compartment and the second the refrigeration compartment, require more careful attention. It is important here that the oil flows into both compressors. If the unit was transported lying down, the waiting time increases in proportion to the number of compressors.
Models with the system deserve special attention. No Frost. In them, the refrigerant circulates through a more complex system of channels, and the presence of fans requires proper operation of the electronics. Oil getting into the air channels or sensors in such systems can lead to incorrect temperature display and constant compressor temperature.
- 🧊 No Frost system: requires complete dryness of the electrical contacts of the fans before turning on.
- ❄️ Inverter type: sensitive to the quality of the lubricant, requires maximum settling time oil.
- 🔌 Smart refrigerators: before connecting to Wi-Fi, make sure that the device has gone through a full primary cooling cycle.
- 🚛 American models: often have large dimensions and heavy compressors, which increases stabilization time refrigerant.
Step-by-step instructions: how to properly prepare a refrigerator
The process of preparing a new refrigerator Must be methodical and calm when approaching work. Do not rush to load products until the unit reaches operating mode. First you need to free the internal space from shipping materials, tape and foam inserts.
Then you should install the refrigerator in the prepared place and level it horizontally using adjustable supports. This is important for proper operation of the doors and quiet operation of the compressor. After this, you need to wipe the internal shelves with a damp cloth to remove factory dust and odors.
☑️ Preparation for the first start
Only after the recommended settling time has passed, can you connect the device to the network. Pay attention to the condition of the outlet: it must be in working order, grounded and match the power consumption of the device. It is not recommended to use extension cords and tees.
The refrigerator should operate empty for the first few hours. This will allow the system to reach the specified temperature without unnecessary load. Loading with products should be done gradually, in small portions, so as not to disturb the temperature balance inside the chambers.
Typical errors and signs of malfunction after switching on
Even if all the rules are followed, nuances may arise that indicate problems. If, after turning on, the refrigerator makes loud knocking, gurgling or buzzing noises that were not present in the store, you should be wary. Only the quiet hum of the compressor and the occasional cracking of the plastic during expansion is considered normal.
A common mistake is to install the refrigerator close to the wall or in a niche without gaps for ventilation. This leads to overheating of the capacitor and increased power consumption. Also, users often forget to remove the shipping bolts (if they are present in a particular model), which causes strong vibration.
If after 5-6 hours of operation the refrigerator does not cool, but the walls inside remain warm, there may be a refrigerant leak or a capillary tube clogged with oil. In this case, you must immediately disconnect the device from the network and contact a service center.
⚠️ Attention: Do not try to open the cooling circuit or add freon yourself. This requires special tools and qualifications, and intervention will break the factory seal.
Why does the refrigerator click when turned on?
The click at start is the sound of the start relay. If the clicks are repeated frequently and the compressor does not start, there may be low voltage in the network or a faulty relay.
Is it possible to transport a refrigerator lying down if there is no other way out?
You can transport it lying down, but this is a risk. Be sure to tell carriers which side to ship on (usually the side where the door hinge is, or as specified in the instructions for the specific model). After such transportation, the downtime should be maximum - at least 12-24 hours.
What will happen if I turn on the refrigerator 1 hour after delivery?
Most likely, nothing bad will happen if it was transported vertically. But if the oil has leaked into the circuit, the compressor may burn out in a few months or even years; its service life will simply expire faster. In this case, the warranty may be void.
Do you need to wash the refrigerator before turning it on for the first time?
Yes, definitely. There may be factory dust, foam particles and the smell of new plastic inside. Wipe the shelves with a weak solution of soda or a special product for household appliances and let dry.
How long does it take the refrigerator to gain temperature after turning it on?
Primary cooling of empty chambers takes from 2 to 6 hours, depending on the volume and power of the model. It may take up to 24 hours for the freezer compartment to completely freeze and the mode to stabilize.
Is the smell of plastic in a new refrigerator dangerous?
A slight smell of new plastic in the first days of operation is normal. It should fade. If the smell is pungent, chemical and does not go away for a week, this may indicate poor-quality materials or overheating of the wiring.
