Buying a new refrigerator is always a joyful event, marking the beginning of a new stage in organizing everyday life. However, the euphoria of the purchase often causes owners to make fatal mistakes in the first minutes of operation, which can lead to serious damage to the compressor long before the warranty period expires. Proper starting is not just plugging into a socket, but a set of preparatory measures, which cannot be ignored.
Modern refrigeration units are complex technical devices that are sensitive to transport influences and temperature changes. Unlike other household appliances, refrigerant and special compressor oil circulate here, which, if improperly transported, can be displaced into system components not intended for them. That is why there is a strict algorithm of actions that must be completed before the first start.
In this article we will analyze in detail all stages of preparation, from unpacking to the first hours of operation in idling mode. You will learn why rushing in this matter can cost you expensive repairs and how to ensure that your equipment has maximum service life from the very first day.
Waiting after transportation: why you can’t rush
The most critical point that most buyers forget about is the acclimatization time. If your new one refrigerator was delivered in the winter season, at sub-zero temperatures, it should absolutely not be plugged into the network immediately after being brought into the room. A sharp temperature change causes moisture condensation inside the electrical circuits and on the contacts, which, when voltage is applied, is guaranteed to lead to a short circuit.
In addition, the viscosity of the compressor oil that is in the system changes at low temperatures. It becomes thick and is not able to effectively lubricate rubbing parts in the first seconds of operation. If you start the unit in this condition, the wear of the piston group or valves will increase many times over, which will reduce the life of the motor.
⚠️ Attention: The minimum waiting time for acclimatization of equipment brought from the cold is 3-4 hours. Only after this will the condensate have time to evaporate and the oil to warm up to room temperature.
The second important factor is the position during transportation. Even if the refrigerator was transported vertically, shaking and tilting could cause oil to flow from the compressor into the evaporator or condenser circuit. It takes time for the oil to flow back into the compressor crankcase under the influence of gravity. If you turn on the unit while the oil is in the tubes, the compressor will work with overload, trying to push the hydraulic plug, which often ends in its failure.
The settling time directly depends on how exactly the transportation was carried out:
- 🕒 If the refrigerator was standing vertically, 2-3 hours are enough.
- 🕒 If the equipment was lying on its side, a minimum of 8-12 hours is required.
- 🕒 If the transportation was in winter, wait at least 4 hours after bringing it into the heat.
What happens if you ignore the settling time?
Turning on the refrigerator ahead of time can lead to water hammer in the compressor. Liquid oil entering the compression chamber does not compress, which causes valve destruction or piston jamming. Repair in this case is often unprofitable.
Unpacking and visual inspection of the case
The unpacking process requires accuracy and attention to detail. First of all, it is necessary to free the unit from the outer cardboard box and packing tape. Do not use sharp objects, such as knives or scissors, in close proximity to the case walls to avoid damaging the enamel or plastic decor. It is better to cut the tape on top and simply remove the box.
After removing the outer packaging, you will see the refrigerator itself, often secured to a foam base with tape or additional belts. Particular attention should be paid to the internal contents. All shelves, drawers, egg trays and packages of documents are usually located inside the cells. They must be removed so that they do not interfere with access to the fastening elements.
At this stage, it is important to carry out a thorough visual inspection check for mechanical damage. Dents, deep scratches or chips may have occurred during delivery. If defects are found, it is better to record them photographically before signing the acceptance certificate or immediately contact the store before the equipment has been installed in place.
Transport bolts and clamps deserve special attention. In some models, the compressor may be secured with special bolts or brackets that prevent it from beating during transportation. Before turning on, these elements must be dismantled, otherwise vibration during operation will be transmitted to the entire case, creating loud noise and destroying the fastenings.
Installation and leveling
Choosing a place to install the refrigerator is not only a matter of aesthetics, but also of technical necessity. The unit must stand on a level, solid base. It is not recommended to install equipment in close proximity to heating appliances, stoves or in direct sunlight, as this will force the compressor to work harder, consuming excess electricity.
A critical point is to ensure free access of air to the rear condenser grille. The minimum distance from the back of the refrigerator to the wall should be at least 5-7 cm, and it is advisable to leave gaps of 2-3 cm on the sides. Violation of these rules leads to overheating of the system and premature wear.
After the refrigerator is installed in place, it must be leveled. This is done using adjustable support feet located on the front bottom of the chassis. To rotate the legs, you usually use an adjustable wrench or a special handle included in the kit.
Correct alignment ensures not only stability, but also the correct operation of the self-closing door system. Doors should open easily and, if released at an angle of up to 30-45 degrees, return to the closed position on their own. If the door does not close itself or, on the contrary, slams too sharply with a bang, it means that the angle of inclination is incorrect.
☑️ Checking the installation
Preparation of internal chambers for work
Before Load food, the internal surfaces of the refrigerator and freezer must be prepared. Factory packaging often leaves a specific technical smell on plastic and metal, which is better to get rid of before use. In addition, there could be particles of dust or foam crumbs left inside.
For initial treatment, a weak solution of baking soda or a special product for cleaning refrigerators is ideal. Do not use aggressive chemicals, abrasive sponges or hot water, as they may damage the shelf covering and internal plastic. Thoroughly wipe all surfaces, including rubber seals on the doors, and wipe them dry with a clean rag.
Pay special attention to removable elements: glass shelves, plastic containers and grilles. It is better to wash them separately under running water and a mild detergent. This will remove factory grease and dust, which inevitably settles during assembly and packaging.
After wet cleaning, leave the refrigerator doors open for 15-20 minutes. This is necessary so that the smell of new plastic and detergents disappears completely, and also so that the insides are completely dry. A humid environment in a confined space is an ideal condition for the rapid growth of bacteria and mold.
⚠️ Attention: Do not use solvents, gasoline or acids to clean the internal chambers. They can react with the plastic, changing its structure and making it brittle, and also poison products in the future.
First use and setting modes
When all the preparatory stages have been completed, the moment of truth comes - the first connection to the electrical network. Make sure that the outlet you connect your refrigerator to is working, grounded, and meets the required power ratings. The use of extension cords and tees is not recommended, as they can cause poor contact and heating.
After plugging the plug into the socket, you will hear the characteristic hum of the compressor starting up. This is normal. Modern models may have protection against restarting, so do not be alarmed if the motor does not start instantly, but after 1-2 minutes. At this time, the electronics checks the network parameters.
Now you need to set the temperature mode. For the first start, it is recommended to set the average values so that the system returns to operating mode at normal speed. For the refrigerator compartment, the optimal value will be +4°C or +5°C, and for the freezer - -18°C.
If your model has a function super-freezing (Super Freeze) or accelerated cooling, you can activate it when loading food for the first time. However, in idle mode, without food, this function is not needed and will only waste the compressor’s resource.
Idling: checking functionality
One of the most common mistakes is immediately loading the refrigerator with food. This is strictly forbidden. The unit must run idle (without products) for at least 2-4 hours. During this time, the chambers will cool down to the set temperatures, and the system will automatically turn off the compressor.
The first cycle of operation allows you to check the tightness of the system and the correct operation of the thermostat. If, after 3-4 hours of operation, a positive temperature in the refrigerator and a negative temperature in the freezer have not established inside the chambers, this may indicate a freon leak or an electronic malfunction.
During idling, listen to the operation of the equipment. Quiet humming of the compressor, gurgling of refrigerant in the pipes (especially in models with No Frost) and clicking of the relay are allowed. However, strong vibrations, knocking, grinding or whistling are signs of a malfunction or incorrect installation.
Only after the refrigerator has turned off on its own (the compressor has stopped, the corresponding indicator, if any, has come on), can you begin to gradually load food. You should not fill the chambers to capacity on the first day; give the system time to adapt to the thermal load.
Table: Typical sounds during the first start
Many users start panic when hearing unfamiliar sounds from new technology. So that you can distinguish normal operation from a breakdown, check out the table of typical noises.
| Sound type | Description | Normal or malfunction? |
|---|---|---|
| Quiet humming | Uniform low-frequency hum | Normal (compressor operation) |
| Gurgling / overflow | Sounds of flowing liquid inside | Normal (circulation freon) |
| Crackling / clicking | Single or serial clicks | Normal (thermal expansion of plastic) |
| Strong vibration of the case | Rattling of walls or shelves | Fault (poor alignment) |
| Whistling or hissing | Sharp piercing sound | Fault (freon leakage) |
Frequent errors at the first launch
Despite the availability of information, users continue to step on the same rake. An analysis of service centers shows that up to 30% of warranty claims are due to violations of the rules of initial operation.
The most serious mistake is an attempt to speed up the cooling process by setting the minimum possible temperature immediately after switching on. This places extreme stress on the compressor, which is forced to work non-stop in an attempt to cool the warm volume of the chamber. As a result, the motor overheats and may burn out.
Another mistake is ignoring the instructions for a specific model refrigerator. Different manufacturers (Bosch, LG, Samsung, Indesit) may have their own nuances. For example, some models require the mandatory removal of shipping gaskets from the evaporator, which is stated only in the small print of the manual.
⚠️ Attention: Technical specifications and installation requirements may vary depending on the model and year of manufacture. Always check the official user manual included in the package or available on the manufacturer’s website.
Do not forget that the correct start of operation is the key to the long life of your refrigerator. By spending a little time on preparation today, you will save significant money on repairs and purchasing products in the future.
Is it possible to turn on the refrigerator through an extension cord?
The use of extension cords is not recommended, especially cheap and long ones. They create additional resistance, which can lead to a voltage drop and overheating of the contacts. If you cannot do without an extension cord, it must be designed for a current of at least 16A and be completely unwound.
How long does it take the refrigerator to reach temperature for the first time?
The time it takes to reach operating mode depends on the volume of the chambers, the ambient temperature in the room and the type of refrigerant. On average, the process takes from 2 to 6 hours. It can take up to 24 hours for food to completely freeze in the freezer.
Do you need to wash the inside of the refrigerator before turning it on for the first time?
Yes, definitely. There may be factory dust inside, the smell of plastic and packaging. Use a weak solution of soda or a special product, then wipe dry thoroughly.
What to do if the refrigerator hums loudly after installation?
Check whether the shipping bolts have been removed from the compressor (if provided by the model). Make sure the refrigerator is level and not touching walls or furniture. Check to see if the shelves or bottles inside are vibrating.
Can you immediately load food after turning it on?
No. Let the refrigerator run idle for at least 2-4 hours until it turns off on its own. Loading warm products will immediately create a critical load on the compressor.
