Buying a new refrigerator is always a joyful event, marking the beginning of the operation of an important household appliance designed to keep food fresh for many years. However, haste in this matter can play a cruel joke: an incorrect first start can significantly reduce the life of an expensive compressor or lead to breakdown of the cooling system. That is why the question of how to properly turn on a refrigerator after purchase is one of the most pressing for owners of new equipment.
There is a common misconception that you just need to plug the cord into the outlet and set the desired temperature. In reality, the process of preparing for the first start requires compliance with a certain time interval, especially if transportation was carried out in winter or during strong shaking. Oil in the compressor The refrigerant must take its natural position, and the refrigerant must be evenly distributed throughout the system before the pistons begin to operate under load.
In this article we will analyze in detail all stages of preparation, from the moment of delivery to the appearance of the first ice cubes in the freezer. You will learn why you should not rush, how to check the tightness of the circuit and what settings are optimal for modern models LG, Samsung or Indesit. Compliance with these simple rules will ensure that your refrigerator will last the period stated by the manufacturer without costly repairs.
Why it is necessary to pause before the first start
The main reason why you cannot turn on the unit immediately after delivery lies in the physical properties of the refrigeration oil and refrigerant. During transportation, especially if the equipment was tilted or shaken, oil from the compressor could flow into the evaporator or condenser circuits. If you start the engine at this moment, it will run “dry,” which will lead to rapid wear of the rubbing parts and possible jamming.
In addition, in winter, the thermal expansion factor is added. Cold air compresses plastic and rubber parts, making them more fragile. Sudden heating when turned on can cause microcracks in seals or tubes. Thermal equilibrium must be achieved naturally, without forced heating by an electric motor.
⚠️ Attention: If the refrigerator was transported lying down or at a strong slope, the settling time should be increased by at least one and a half times compared to vertical transportation.
It is also worth considering that modern inverter compressors used in models Bosch and Siemensare more sensitive to the quality of lubrication than their old linear counterparts. Violation of the lubrication regime in the first minutes of operation can be fatal for complex control electronics.
Settling time: how long to wait in different conditions
Time required wait before turning on directly depends on the conditions in which the device was located before installation. There is no single figure for all cases, since ambient temperature and transport position play a decisive role. Below is a table to help you navigate the optimal time intervals.
| Transportation conditions | Air temperature | Recommended rest time |
|---|---|---|
| Vertical, without strong shaking | Warm season (+15°C and above) | 2-4 hours |
| Vertical, strong vibration | Any | 4-6 hours |
| Horizontal (lying down) | Warm season | 8-12 hours |
| Any position | Winter time (below 0°C) | 12-24 hours (until it warms up completely) |
If you brought the refrigerator in winter from the cold, it is strictly forbidden to turn it on immediately. It is necessary to let it warm up to room temperature so that condensation does not form inside the case, which can cause a short circuit in the electrical circuit. Moisture condensation on the contacts is the hidden enemy of electronics, which does not manifest itself immediately, but after several weeks of operation.
If the unit has been transported lying down, the oil could completely leave the compressor and fill the tube system. In this case The minimum settling time is 8 hours, but it is better to leave it alone for a day. This ensures that all the liquid flows down under the influence of gravity.
Preparation for installation: choosing a location and level
Before thinking about connecting to the network, it is necessary to properly prepare the installation site. The refrigerator should not be placed close to a wall or furniture, as the heat exchanger requires free air circulation to operate effectively. The gap with the back wall should be at least 5-7 centimeters, and on the sides - at least 2-3 centimeters.
A critical point is the alignment of the case. Incorrect installation leads to the fact that the doors may open by themselves or, conversely, not close completely, breaking the tightness. In addition, the misalignment causes an uneven load on the compressor frame, which increases vibration and noise during operation.
- 📏 Use a building level to check the horizontal position of the top panel.
- 🔧 Adjust the height of the front legs using a special wrench or pliers.
- 🚪 Check that the door closed on its own when opened to 45 degrees.
- 🌡️ Make sure there are no heat sources nearby (radiator, stove, oven).
For models with a system No Frost ventilation is especially important, since overheating of the compressor due to poor heat dissipation can lead to an emergency shutdown or breakdown. Make sure that the ventilation grilles, if your model has them, are not closed.
Primary treatment and hygiene inside the chambers
The inside of a new refrigerator often has a specific smell of plastic and technical lubricants remaining after factory testing. Before loading products, it is necessary to thoroughly wet clean all internal surfaces. This will not only eliminate unpleasant odors, but also wash away industrial dust.
Use a weak solution of baking soda or a mild detergent that does not contain abrasive particles. Thoroughly wipe down shelves, drawers and door seals. Pay special attention to the corners of the chambers, where dust could accumulate during storage in a warehouse.
⚠️ Attention: Never use aggressive chemicals, acetone or boiling water to wash plastic elements. This can lead to cracks and destruction of the plastic structure.
After wet cleaning, be sure to wipe all surfaces dry with a clean rag and leave the doors open for 1-2 hours to completely remove moisture and odors. Only after this can you begin the electrical connection.
Step-by-step algorithm for first switching on
When all the preparatory stages have been completed, the time has passed and the insides are clean, you can move on to the most crucial moment. Follow a strict sequence of actions to minimize risks.
☑️ Checklist for the first start
First make sure that the electrical cord and plug are not damaged. Connect the device to a separate grounded outlet. The use of extension cords or tees is not recommended as compressor inrush currents can be high for thin wires. After connecting to the network, the refrigerator may make a quiet click - this is normal, the start relay is activated.
Do not rush to download products right away. Let the refrigerator run idle for at least 2-3 hours. During this time, it will reach the required temperature, and the automation will turn off the compressor. If after 3-4 hours of operation the motor does not turn off and the inside does not get cold, there may be a freon leak or the thermostat is faulty.
Use the control panel to set it up. On mechanical models, turn the dial to the middle of the scale (usually 2 or 3 out of 5). In electronic models, such as Haier or Atlant, set the temperature to +4°C for the refrigerator compartment and -18°C for the freezer.
What should you do if the refrigerator hums after turning it on?
Humming in the first hours of operation is normal. The refrigerant actively circulates through the system, and the new compressor goes through the process of grinding in parts. If the sound is not accompanied by knocking or squealing, there is no need to worry.
Operation control and loading with food
After the refrigerator has been idle for several hours and has returned to operating mode, you can begin to fill it. However, there are rules here too. You should not load a large amount of warm products at once, as this will cause the compressor to work under overload for a long time.
Fill the chambers gradually, throughout the day. Place foods that require deep refrigeration first in the freezer, then in the refrigerator. Distribute them evenly so as not to block the flow of cold air, especially in systems Total No Frost.
- 🥩 Place food in small portions in the freezer compartment.
- 🥛 Do not place hot or warm foods in the refrigerator compartment.
- 🥤 Do not fill the chambers to capacity, leave gaps for circulation.
- 📦 Pack products so that they do not transfer odors to each other.
On the first day of operation, carefully monitor the operation of the device. It can turn on and off more often than usual - the process of stabilizing the temperature inside a large volume is underway. If after 24 hours the temperature inside the chambers does not correspond to the set values, you must contact the service center.
Typical errors during the first start
Even following the instructions, users often make mistakes, which can cost the technology its longevity. One of the most common is ignoring electrical requirements. Connecting to an unstable network without a stabilizer can damage the control board, especially in expensive models with electronics.
Another mistake is installing the refrigerator in a niche without gaps for ventilation. Many built-in models require a special box or cabinet with ventilation holes. Violation of this rule leads to overheating of the condenser and increased energy consumption.
⚠️ Attention: If you notice that the side walls of the refrigerator get very hot in the first days of operation, do not be alarmed. In modern models, the sator is often built into the side walls, and their heating to 40-50°C is a sign of normal operation, not a malfunction.
It is also a mistake to believe that the lower the temperature, the better. Setting the minimum values immediately after purchase puts extreme stress on the system. Start with average values, and only adjust them if necessary.
Frequently asked questions (FAQ)
Is it possible to turn on the refrigerator immediately if it was transported only in the summer and vertically?
Yes, if the transportation was vertical, without strong shaking and tilting more than 40 degrees, it is enough to give stand for 1-2 hours to stabilize the refrigerant pressure. However, 4 hours is a safer standard.
Why doesn’t the refrigerator freeze in the first hour after being turned on?
This is normal. The compressor takes time to create pressure and cool the entire volume of the chambers. In the first 30-60 minutes, a significant decrease in temperature may not be felt.
Is it necessary to defrost a new refrigerator before first use?
No, new refrigerators, even with manual defrosting, are sold dry and clean. It is enough to simply wipe them with a damp cloth to remove dust and odors.
What to do if the refrigerator vibrates a lot?
Most likely, the adjusting feet are not set correctly. Check the horizontal installation with a level and tighten the legs to a stable position without swinging.
Is it dangerous to use an extension cord to connect the refrigerator?
Manufacturers do not recommend using extension cords. If you cannot do without them, make sure that the cross-section of the extension cable corresponds to the power of the refrigerator, and the wire itself is completely unwound from the coil.
