Buying a new refrigerator is always a joyful event, marking the beginning of comfortable operation of the equipment, but joy often gives way to impatience when you want to load food faster. At this point, many make the fatal mistake of turning on the unit immediately after unpacking or bringing it into the apartment, without waiting for the temperature of the internal components to stabilize. Such a hasty action can lead to serious damage to the compressor, reduced motor life, and even complete breakdown of expensive equipment in the first weeks of use.
In addition, incorrect installation often causes increased noise, vibration and incorrect operation of the condensate drainage system, which creates discomfort when living in the kitchen. Proper preparation the first start-up includes not only endurance time interval, but also proper positioning of the case, checking the level and adjusting temperature conditions. Ignoring these simple but critical steps can turn a new purchase into a source of ongoing problems that require expensive repairs.
In this article we will analyze in detail all stages of preparation, from the moment of delivery to loading the first products, so that your refrigerator serves long and reliably. You will learn why the holding time depends on the method of transportation, how to set the optimal microclimate inside the chambers and what actions are strictly prohibited on the first day of work.
Exposure time intervals after transportation
The most important stage, which cannot be ignored under any circumstances, is the wait before the first connection to the electrical network. During transportation, especially if it was carried out in a passenger car or on an incline, oil from the compressor could flow into the cooling system circuits, in particular into the evaporator or condenser. If you turn on the unit immediately, the compressor will begin to run dry, which will lead to rapid wear of the rubbing parts and possible water hammer.
The duration of the settling period directly depends on the position in which the device was transported and what the ambient temperature was. If you transported equipment vertically, without strong tilts, and it was warm outside, it is enough to wait 2-3 hours for the condition of the refrigerant and oil to stabilize. In cases where the refrigerator was lying horizontally or transported at subzero temperatures, the waiting time increases to 12-24 hours.
⚠️ Attention: It is strictly forbidden to plug in the appliance if it has just been brought in from the cold. Sudden temperature changes will cause condensation to form on electronic boards and contacts, which can lead to a short circuit when voltage is applied. Allow the equipment to warm up to room temperature for at least 4-6 hours.
For the convenience of users, below is a table that helps determine the required holding time depending on delivery conditions:
| Transportation conditions | Ambient temperature environment | Recommended exposure time |
|---|---|---|
| Vertical (without tilting) | Above 0°C | 2-4 hours |
| Horizontal (lying position) | Above 0°C | 8-12 hours |
| Vertical or horizontal | Below 0°C (in winter) | 12-24 hours (after warming up) |
| Strong shaking | Any | At least 12 hours |
Compliance with these time frames ensures that the oil has time to drain back into the compressor crankcase, and the refrigerant is distributed evenly throughout the system. Patience in this case, is the key to the durability of your equipment, allowing you to avoid expensive repairs during the warranty period.
Selecting an installation location and surface preparation
Before proceeding with the final installation, you must carefully select the location where your new refrigerator will be located. Ventilation is a key factor affecting the efficiency of the compressor and electricity consumption. Modern models require free access of air to the back wall and side panels for heat removal, so you cannot move the equipment close to the wall or furniture.
The optimal distance from the back wall of the refrigerator to the wall of the room should be at least 5-7 centimeters, and it is advisable to leave gaps of 2-3 centimeters on the sides. If you plan to build a refrigerator into a niche or kitchen unit, make sure that the cabinet design provides for ventilation holes at the top and bottom, as well as at the back.
The surface on which the unit is installed must be perfectly flat, hard and stable. The floor should not sag under the weight of a refrigerator filled with food, as this can cause the body to sag and the door mechanisms to malfunction. If the floor is uneven, use the leveling feet, which are usually located at the front bottom of the cabinet.
- 📏 Check the distance to the walls: leave at least 5 cm at the back for air circulation.
- 🧱 Make sure the floor can support the weight: a full refrigerator can weigh more than 100 kg.
- ☀️ Avoid direct sunlight and proximity to heating devices (radiators, stoves).
- 🔌 The outlet should be easily accessible and grounded; the use of extension cords is not recommended.
It is also important to consider the proximity of heat sources. Installation near a gas stove, oven or radiator will cause the compressor to work harder in an attempt to compensate for external heat, which will lead to increased energy consumption and accelerated wear.
Removing packaging and shipping elements
The process of unpacking a new refrigerator requires care and attention, since damage to the case or internal components due to careless handling may void your warranty. The outer cardboard packaging protects the equipment upon delivery, but inside there are additional fixing elements that must be removed before use.
First of all, remove all pieces of tape securing the doors and drawers. Manufacturers often use special tapes or brackets to keep doors from opening during transport. After removing them, check whether the doors open and close freely and whether there are any foreign objects blocking the movement.
Particular attention should be paid to the internal space. Remove all shelves, drawers, egg trays and packing foam. Often inside you can find bags with documentation, warranty cards and instructions, which also need to be removed. Wipe the interior surfaces thoroughly with a soft, damp cloth to remove any factory dust or possible manufacturing residues.
⚠️ Attention: Some models may have shipping bolts or clamps on the compressor (although this is less common in household refrigerators than in washing machines). Carefully read the instructions for your model LG or Boschto make sure that all fixing elements are removed.
After cleaning the insides, move on to the exterior. Remove the protective film from the doors and cabinet, if any. This must be done carefully so as not to scratch the surface, especially if the refrigerator has a stainless steel coating or imitation metal.
☑️ Check before turning on
First switching on and setting temperature conditions
After the refrigerator has stood for the required time and has been freed from packaging, you can proceed to the most important moment - the first switching on. Plug the power cord into a grounded outlet. Make sure that the voltage in the network is stable and meets the requirements specified in the technical documentation (usually 220-240 Volts).
Immediately after turning on, you will hear a quiet hum of the compressor starting up - this is normal. In modern models with the system No Frost or Full No Frost starting the fans is also a standard procedure. Let the device run idle (without food) for 2-4 hours so that it reaches the set temperature parameters in all chambers.
It is better to set the temperature according to the manufacturer’s recommendations, which are usually indicated in the instructions. Standard values for the refrigerator compartment are +3...+5°C, and for the freezer compartment -18°C and below. The adjustment is carried out through a mechanical regulator (thermostat) or an electronic control panel located on the door or inside the chamber.
If your model is equipped with electronic control, the transition to the settings menu may look like this:
Menu → Settings → Temperature → Fridge: +4°C / Freezer: -18°CIt is important not to overload the refrigerator with food during the first hours of operation. A sharp increase in the temperature inside the chambers due to loading a large volume of warm food will force the compressor to work at its limit, which is undesirable for a new engine.
What to do if the refrigerator does not cool after turning on?
If after 4-5 hours of operation the temperature inside does not decrease, check whether the doors close tightly, whether there are any obstacles to air circulation at the back and whether the settings are set correctly thermostat. In some cases, it may take up to 12 hours to reach the mode at high ambient temperatures.
Checking the tightness and operation of door seals
The tightness of the refrigeration chamber is the foundation for energy efficiency and high-quality operation of the entire system. A loose fit of the door leads to a constant influx of warm, moist air from the room, which causes freezing of the evaporator, frequent compressor cycles and the formation of ice.
Inspection of the seals (rubber cuffs around the perimeter of the door) must be carried out visually and tactilely. Make sure that the rubber fits snugly along the entire length of the body and has no creases, cracks or dirt that could have gotten there during transportation. If you notice any leaks, try gently straightening the seal with your hands or gently warming it with a hairdryer at low temperature (be careful not to melt it).
There is a simple and effective way to check the seal using a regular sheet of paper. Open the door, place the sheet on the seal and close the door. The sheet must be clamped along the entire length of the seal. If the paper falls out or is pulled out too easily without resistance, then the seal is broken in that area.
- 📄 Carry out a test with a sheet of paper around the entire perimeter of the door.
- 👀 Inspect the seal for wrinkles or peeling from the plastic.
- 🧼 Wipe the elastic with a soft cloth soaked in a mild soap solution for a better fit.
- 🚪 Make sure that the shelves on the door do not interfere with tight closure.
In some cases, loose closure is not caused by a defect in the seal, but by incorrect tilting of the body. If the refrigerator is tilted backwards, the door may open on its own or not close completely. Adjust the front legs so that the body is slightly tilted back (the back is slightly lower than the front).
Loading food and operating instructions
Only after the refrigerator has been idle for several hours and has reached the desired temperature, can you start filling it with food. However, there are also rules here, the violation of which can negate all previous efforts for proper installation.
The first download should be moderate. You shouldn't fill your cameras to capacity on the first day. Place food evenly, leaving small gaps between them to allow free circulation of cold air. This is especially true for models with a system No Frostwhere air flows play a key role in cooling.
It is strictly forbidden to place hot or even just warm foods in the refrigerator. This places extreme stress on the compressor and dramatically increases the humidity inside the chamber, leading to the formation of condensation and ice. All products must be at room temperature or refrigerated before being sent for storage.
Distribute products according to temperature zones:
- 🥩 Lower shelves: raw meat, fish, semi-finished products (the coldest here).
- 🥛 Middle shelves: dairy products, ready meals, sausages.
- 🥬 Bottom drawers: vegetables and fruits (optimal humidity here).
- 🚪 Door shelves: sauces, drinks, eggs (the area with the greatest temperature fluctuations).
Following these simple rules will help your new refrigerator enter operating mode smoothly, without stress for the compressor, and will ensure long-term preservation of the freshness of your products.
Is it possible to turn on the refrigerator immediately after delivery in winter?
No, if the refrigerator was brought in from the cold, it cannot be turned on for at least 4-6 hours. The condensation formed on the internal components due to temperature changes must be completely dry, otherwise the electronics may be briefly washed out.
Why does a new refrigerator make loud noise in the first hours?
In the first 24 hours of operation, the compressor may operate more intensely and noisily, as the system reaches its nominal cooling mode. There may also be noise from the refrigerant circulation. If the noise does not subside after a day and is accompanied by vibration, check the level of the installation.
Do you need to wash a new refrigerator before use?
Yes, definitely. Factory dust or the smell of plastic or packaging may remain inside. Wipe all interior surfaces, shelves and drawers with warm water and a mild detergent or soda solution, then wipe dry.
What to do if the refrigerator door does not close tightly?
Check if there is anything in the way from the inside (packaging, food), whether the shelves are installed correctly, and adjust the legs of the refrigerator. Also check the integrity of the rubber seal. If the problem persists, contact the service center.
How long does it take the refrigerator to reach the temperature after switching on?
Usually, to reach the set temperature values (+4°C in the refrigerator compartment and -18°C in the freezer), a new refrigerator takes from 2 to 6 hours, depending on the volume of the chambers, ambient temperature and model compressor.
