Buying a new household appliance is always a pleasant event, marking an increase in comfort in the home, but the joy of the purchase can be overshadowed if ignored basic operating rules. Many owners make the mistake of starting up the unit as soon as the delivery guys take the box away, without considering that transportation is a significant stress on the compressor and refrigerant. Incorrect actions in the first hours can lead to breakdown of expensive components, so knowing how to turn on the refrigerator after purchase is a critical skill for every user.
The process of activating the device requires patience and careful attention to the details specified in the manufacturer's technical documentation. Unlike small kitchen appliances, which can be used straight out of the box, refrigeration equipment needs to adapt to new environmental conditions and restore internal balance after transportation. In this article, we will analyze in detail all stages of preparation, from unpacking to the first loading of products, so that your new device will serve for many years without failures.
Particular attention should be paid to the temperature conditions in which the device was during delivery, especially in the cold season. A sharp temperature change when bringing equipment from frost into a warm room can cause the formation of condensation on electrical components, which can lead to a short circuit. Patience in this case, it is not just a virtue, but a technical necessity that allows you to avoid expensive repairs.
Transportation and settling time before switching on
The most important stage preceding the first start-up is the time required to stabilize the state of the refrigerant and compressor oil. During transportation, especially if the unit has been subjected to tilting or vibration, oil from the compressor may flow into the cooling system circuits and refrigerant may be displaced. If you turn on the unit immediately, the compressor will work in increased load mode, trying to push the oil plug, which can lead to jamming or failure of the valves.
The time that must be waited before connecting to the network directly depends on the position in which the device was transported. If the refrigerator was transported strictly vertically, without strong shaking or tilting, it is enough to let it stand for 2–3 hours. If the equipment was transported lying down or with a strong list, the settling time increases to 8–12 hours, and in some cases, especially for models with inverter compressors, manufacturers recommend waiting a full day.
⚠️ Attention: If the refrigerator was delivered in winter at sub-zero temperatures, do not turn it on immediately after bringing it into the apartment. Let it warm up to room temperature for 4-6 hours to avoid condensation on electronic boards and damage to wire insulation.
It is also worth considering that different types of refrigerants and design features of compressors dictate their own requirements. For example, models running on R600a gas (isobutane) are more sensitive to the presence of oil in the system, so for them, observing a rest period is a strict recommendation. Ignoring this rule often becomes the reason for refusal of warranty service, since service centers easily determine violation of operating conditions by the condition of the compressor.
Installation and preparation for the first launch
After the device has been left for the required time, you need to choose the right place to install it. The refrigerator should not be placed close to a wall or furniture, since the cooling system requires free air circulation around the condenser to operate effectively. Typically, manufacturers require a gap of at least 5-10 cm to be left from the back wall and side surfaces to the nearest obstacles, which ensures heat dissipation and prevents overheating of the motor.
The next step is to remove all shipping packaging, including protective film, foam inserts and, most importantly, the tape securing the internal shelves and doors. Often, users forget to remove protective stickers from the internal surfaces or leave the fixing elements on the doors, which can lead to deformation of the seals or breakage of the opening mechanisms during the first use.
A critical point is leveling the device horizontally. Incorrect installation may result in the door not closing tightly on its own or, conversely, slamming too abruptly. To adjust, use the screw supports at the bottom of the case, controlling the position using a building level. Stinol, Indesit and many other brands equip their models with adjustable legs for this very purpose.
☑️ Check before turning on
Don't forget to check integrity of the rubber seals on the doors. They should be clean, elastic and fit snugly all around. If there are creases or dirt on the rubber, the seal of the chamber will be compromised, which will lead to constant operation of the compressor and the formation of ice. Wipe the seals with a soft, damp cloth before starting for the first time.
First connection to the electrical network
The refrigerator must be connected to the electrical network into a separate grounded outlet. The use of extension cords, tees or low-quality surge protectors is not recommended, as compressor inrush currents can cause contact heating and even fire. If there is no separate outlet, make sure that the extension cord you are using is designed for a current of at least 16 Amps and has high-quality insulation.
When you turn it on, you may hear a characteristic click or hum - this is normal, as the compressor starts working. Modern electronically controlled models can first turn on the backlight and display, and the compressor will start within a few minutes after the system self-diagnosis. At this time, do not open the doors or try to change the settings, let the electronics complete the initial test cycle.
| Compressor type | Nature of operation | Features of the first start |
|---|---|---|
| Normal (linear) | Cyclic (on/off) | The start click is heard, can work for a long time without shutdowns |
| Inverter | Smooth, without stopping | Works quietly, gradually gains power, no sudden sounds |
| Linear inverter | Piston principle, smooth running | Minimum vibration, quick entry to mode |
Pay attention to the behavior of the device in the first hours of operation. The compressor may not turn off for a long time (up to 24 hours), especially if the chamber is warm. This is the normal operating mode for the initial cooling of the internal volume and walls of the chamber. Don't panicif the refrigerator hums continuously during the first day, it performs its main function of creating a reserve of cold.
Why does the refrigerator spark when turned on?
Sometimes when the plug is connected to plug you can see a small spark. This is normal for equipment with large capacitors and powerful motors. However, if the sparking is accompanied by a burning smell or is repeated constantly, immediately turn off the device and check the socket.
Setting the temperature mode
After the device has worked for several hours and has reached minimum temperatures, it is necessary to set the optimal operating mode. Factory settings are often averages and may not suit your needs or room conditions. For mechanical regulators, it is usually recommended to set the switch to the middle position, which corresponds to a temperature of about +4°C in the main chamber.
Electronic control panels allow you to set the exact temperature in 1-degree increments. The optimal value for storing most products is considered to be from +3°C to +5°C. It is recommended to set the freezer to -18°C, which ensures long-term storage of products without loss of quality. Models Bosch i Siemens
⚠️ Attention: Do not set the minimum possible temperature immediately after purchase. This will place excess load on the compressor and may cause food to freeze at the rear wall. Start with average values.
If your refrigerator has a freshness zone (zero chamber), make sure it is activated and configured correctly. In some models, the temperature in this compartment is regulated separately or depends on the position of the damper supplying cold air. Correct setting of this zone will significantly increase the shelf life of meat, fish and vegetables.
First loading with food
You can load the refrigerator with food only after it has reached operating mode and reached the required temperature. Typically this process takes from 4 to 12 hours depending on the volume of the chambers and the power of the device. If you put warm food in a chamber that has not cooled down, the compressor will work hard, trying to cool a large amount of heat, which will shorten its life.
Distribute the food evenly, do not cram the shelves. For effective circulation of cold air, small gaps must be left between products. This is especially important for models with a system No Frost, where air flows pass through special channels. If you cover the openings with food, the cold will not be distributed evenly, and ice may form in some corners.
Do not place hot or warm food inside the chambers. This will not only increase energy consumption, but will also create a favorable environment for the growth of bacteria in other products. Allow food to cool to room temperature before storing. Also avoid storing food in open containers, use containers or cling film to prevent the absorption of odors.
Typical sounds and behavior of a new refrigerator
In the first days of operation, you may hear sounds that were not previously characteristic of your old equipment. Modern refrigerators, especially those with inverter compressors and new types of refrigerants, may produce gurgling, shimmering sounds or a slight hissing sound. This is normal and indicates the circulation of freon in the piping system.
Crackling or clicking noises may also appear caused by thermal expansion and contraction of plastic and metal parts of the housing when the temperature changes. These sounds do not indicate a problem and usually become less noticeable after a few days of operation. However, if you hear a loud knock, grinding metal or humming that turns into vibration, you should contact the service.
Pay attention to the heating of the side walls. In many models, the condenser is built into the side panels, so heating them to 40–50°C is a normal operating process for heat removal. Warm sides is a sign that the cooling system is functioning properly, and not an assembly defect.
Frequently asked questions (FAQ)
Is it possible to turn on the refrigerator immediately after delivery if it has not been tilted?
Yes, if transportation was carried out strictly in a vertical position without shaking; it is enough to let the device stand for 2–3 hours to stabilize temperatures and pressure. However, if there is the slightest doubt about maintaining verticality, it is better to increase the settling time to 4–6 hours.
What to do if the refrigerator was running during transportation?
If you accidentally turned on the refrigerator in the car or it was working in the store, let it stand turned off for at least 6–8 hours. This will allow the oil to completely drain into the compressor crankcase and prevent water hammer the next time it is started.
Why does the refrigerator not freeze in the first hours after switching on?
It takes time for the initial cooling of a large volume of air and the walls of the chambers. Depending on the model and room temperature, reaching the mode may take from 4 to 12 hours. Do not load food until the required temperature has been reached.
Do you need to wash the inside of the refrigerator before first use?
Yes, be sure to wipe the internal chambers with a damp cloth and a mild detergent or soda solution. This will remove dust, factory grease residue and the smell of new plastic, ensuring hygienic food storage.
Is it dangerous if the refrigerator makes a loud noise on the first day?
On the first day, the compressor works continuously, cooling the empty chamber, so the sound may be more noticeable. If the hum is monotonous and is not accompanied by body vibration or knocking, this is normal. After a couple of days, the operating mode will stabilize.
