Buying new household appliances is always an exciting moment, promising comfort and safety of products. However, the euphoria of the purchase often makes one forget about the critical nuances of the initial start-up, which directly affect the service life of the compressor and the quality of cooling.
Many users make the fatal mistake of plugging the unit into the network immediately after delivery, without taking into account the time required to stabilize the refrigerant and lubricants. In this article, we will analyze in detail each stage of preparation so that your device operates silently and efficiently for many years.
Incorrect start of operation can lead to increased noise, excessive energy consumption, or even failure of an expensive compressor. Let's look at how to avoid these problems and provide ideal conditions for the “new settler” in your kitchen.
Transportation and acclimatization time
The first thing the owner faces after purchase is delivery. If the unit was transported in a horizontal position, which movers often do to save space, oil from the compressor it could leak into the refrigerant circuit. Turning on the equipment in this state is equivalent to running a car engine without oil: friction of parts will lead to rapid wear.
Even with vertical transportation, the device needs time to acclimatize. Sudden temperature changes, especially in winter, cause condensation to form inside electronic boards and on metal elements. Humidity can cause a short circuit during the first start.
How long should you wait? The minimum standing time is from 4 to 8 hours at room temperature. If the equipment was brought from the cold, this period should be increased to a day so that all internal components warm up to room temperature naturally.
Do not rush to remove transport locks and protective films ahead of time. They protect the housing and internal mechanisms from damage while moving around the apartment.
⚠️ Attention: If you turn on a device that has just been brought in from the cold, the thermostat may incorrectly read the temperature, which will lead to an endless cycle of the compressor operation or its complete failure.
Removing the packaging and external cleaning
After the equipment has “settled”, it is necessary to carefully remove all packaging materials. Tape, foam inserts, cardboard and protective film - all this must be completely removed before starting work. Pay special attention to the inside of the door, where bottle holders or instructions are often attached.
The next step is to remove the factory protective film from the external and internal surfaces. Many people forget to do this right away, and over time the glue dries out, and it becomes almost impossible to tear off the film without leaving marks. In addition, plastic without air access may change color or become deformed.
Be sure to remove all shelves, drawers and trays. They also need to be washed, but we will talk about this in the next section. For now, focus on the body: wipe it with a soft cloth to remove dust that has settled during storage in the warehouse.
What to do if the adhesive tape does not come off?
Use a hair dryer to slightly heat the adhesive base, or use a special sticker remover. Do not use sharp objects to avoid scratching the coating.
Hygiene: wash before first use
There may be a specific smell of plastic or technical lubricants inside the new refrigerator. To prevent future products from absorbing these aromas, the chamber must be thoroughly washed. Use warm water with baking soda or a mild soap solution.
It is strictly forbidden to use abrasive powders, hard brushes or aggressive chemical solvents. They can damage the antibacterial coating of the walls or scratch the transparent plastic of the shelves, which will lead to the formation of cracks in the future.
After wet cleaning, all surfaces should be wiped dry with a clean soft cloth. Be sure to rinse the removable elements separately under running water and allow them to dry completely before installing them back.
- 🧼 Use a baking soda solution (1 tablespoon per liter of water) for safe disinfection.
- 🚫 Avoid chlorine-containing products, which can corrode plastic and rubber seals.
- 💨 Leave the doors open for 1-2 hours after washing to completely remove odors.
Installation and alignment housing
The correct location is the key to quiet operation and energy saving. The device should not be placed close to a wall or furniture. To effectively remove heat from the condenser (radiator), free air circulation is required.
The optimal distance to the back wall is at least 5-7 cm, and at least 5 cm on the sides. If you plan to build equipment into a niche, make sure that ventilation is provided there, otherwise the compressor will wear out.
A critically important point is alignment. A refrigerator that is not level will vibrate, make noise, and, most unpleasantly, the doors may not close tightly or open spontaneously. Adjustment is carried out using the front support legs.
☑️ Checking the installation
Use a building level to check. If you don’t have it, you can pour some water into a glass and put it on the lid (if it’s level) or visually assess the top line. The door should open easily and close itself if it is released when opening 45 degrees.
| Parameter | Recommended value | Consequences of violation |
|---|---|---|
| Distance to the wall | 5-7 cm | Compressor overheating, noise |
| Tilt of the body | Forward 1-2 degrees | Spontaneous opening of doors |
| Gap on the sides | Minimum 5 cm | Poor ventilation, condensation |
| Stability | No wobbling | Vibration, rumble during operation |
First turn on and adjusting temperatures
The moment of truth has come - connecting to the power grid. Make sure that the outlet is grounded and matches the power rating of the appliance. It is not recommended to use extension cords or tees, especially if the wiring in the house is old.
After connecting to the network, do not rush to load products. The refrigerator needs time to reach operating temperature in empty chambers. Typically this process takes from 2 to 4 hours, depending on the volume and model.
In modern models with electronic control (No Frost, Multi-Air Flow), the initial setup is done through the control panel. Set the average values: +4°C for the refrigerator compartment and -18°C for the freezer.
Mechanical thermostats usually have a rotary knob with numbers from 1 to 7. It is optimal to set the regulator to position 3 or 4. The “Max” or 7 position forces the compressor to work continuously, which is not necessary in normal mode.
During the first operating cycle, listen to the sounds. A slight gurgling sound is normal (refrigerant circulation). A loud knock, clanging or high-pitched whistle indicates a malfunction or incorrect installation.
Loading food: rules and terms
When the refrigerator has reached the set temperature, you can start loading. However, this must be done gradually. Suddenly filling a large volume with warm products will cause a temperature jump and force the unit to work in intensive mode for several hours.
Fill the freezer first as it takes longer to freeze. Then move on to the refrigerator compartment. Try not to block the ventilation openings inside the chamber, if any.
Do not place hot or warm food inside. This is not only harmful to equipment, but also disrupts the temperature conditions for storing other products. Allow food to cool to room temperature before putting it on the shelf.
- 🥩 Arrange foods so that cold air can circulate freely between them.
- 🥛 Place dairy products and meat on the coldest shelves (usually the top or bottom, depending on the model).
- 🥦 Place vegetables and fruits in special vegetable boxes, where the humidity is higher and the temperature is slightly higher.
⚠️ Attention: Fully loading the chambers to the brim in the first day of work is not recommended. Allow the system to stabilize at partial load.
Frequent errors during first startup
Even careful study of the instructions does not always save you from the typical mistakes that many users make. One of the most common is ignoring the operating instructions for a specific model. Different brands (LG, Samsung, Indesit) may have their own nuances.
Often users forget to remove the transport bolts or clamps from the compressor, if they are provided for in the design (although in modern household models this is less common than in washing machines, but it’s worth checking). Another common mistake is to install the device near heat sources: a radiator, stove, or in direct sunlight.
Some try to speed up the cooling process by opening the door every 10 minutes to “check” the cold. This disrupts the process and disrupts automation. Trust the technology and indicators.
Why can’t you place a refrigerator near a battery?
The heat from the battery heats the condenser, the cooling efficiency drops, the compressor works without interruption, which leads to breakdown.
FAQ: Answers to popular questions
How much How long can you not turn on the refrigerator after delivery in winter?
If the refrigerator was delivered at subzero temperatures, it must be allowed to warm up to room temperature within 3-4 hours (or better yet, 24 hours). Turning on a cold appliance will cause condensation to form on electronic components and may cause a short circuit. Also, the thickened oil in the compressor should return to the crankcase.
Is it necessary to wash the inside of a new refrigerator?
Absolutely. Factory dust, plastic particles or technical odors may remain on the internal surfaces. Rinsing with warm water and soda or a mild detergent will ensure hygienic cleanliness and absence of foreign tastes in the products.
Why does a new refrigerator run loudly in the first days?
During the initial start-up period, the compressor may work harder and longer than usual to cool the entire volume of the chambers. The sound of refrigerant flowing may also be heard. If after 2-3 days the noise does not decrease or a knocking noise appears, you should contact service.
Is it possible to immediately load a full refrigerator with food?
Not recommended. It's best to load foods gradually over the first 24 hours. A sudden heat load can overload the compressor at start-up. Allow the system to reach a stable operating mode with empty or partially filled chambers.
What to do if the door of a new refrigerator does not close tightly?
Check whether anything is interfering with the seal (packaging, label). Make sure the refrigerator is level and tilted slightly backwards. If the door is skewed, the hinges may need to be adjusted, but this rarely happens in a new device.
