Moving to a new apartment or simply changing your place of residence is always stressful, associated with a huge number of tasks. One of the most difficult and responsible procedures is the movement of large household appliances, in particular refrigeration equipment. Owners often wonder not only about how to carry the unit to the elevator, but also about when they can finally plug the cord into an outlet. Mistakes at this stage can be very expensive, up to the need for a major overhaul of the compressor or a complete replacement of the freon line.
Haste in this case is the main enemy. Many, tired of loading and unloading, strive to quickly load products and start the equipment so that it begins to cool. However, the physics of the processes occurring inside of the refrigeration circuit during shaking and tilting requires time to stabilize. Ignoring the rules for settling equipment can lead to you hearing a loud knock, hum, or, worst of all, silence instead of the usual hum of the engine.
In this article we will analyze in detail why you need to wait, what determines the duration of this period and how to properly prepare the unit for the first start after the road. We will consider various scenarios: transportation in an upright position, transportation lying on its side, and even extreme cases of moving in cold weather. Understanding these nuances will help extend the life of your Samsung, LG, Indesit or any other brand.
Why you can’t turn on the refrigerator immediately after transportation
The main reason for the ban on instant start lies in the design of the compressor. This is the heart of the refrigerator, which works due to the circulation of refrigerant and special compressor oil. In normal operation, oil is located in the lower part of the compressor (crankcase) and provides lubrication of rubbing parts. However, during transportation, especially if the unit has been subjected to shaking, shock or tilting, the oil will inevitably move.
It may leak into the refrigerant circuit, enter the evaporator or condenser. If you turn on the equipment immediately, the compressor will start to run dry, without proper lubrication, which will lead to rapid wear of the piston group. Moreover, an oil plug in the tubes can create excess pressure, which simply will not allow freon to circulate, or the oil will enter the high-pressure zone, causing a water hammer.
⚠️ Attention: An attempt to start the compressor with oil that has entered the system can lead to jamming of the piston group. In 90% of cases, this means an expensive replacement of the compressor, since repairing the old one is often not economically feasible.
In addition, during transportation in the cold season, condensationis formed on the internal parts. Moisture needs time to evaporate naturally. If you turn on the electrics in a humid environment, a short circuit or failure of the thermostat or control board may occur. That is why a pause before the first switching on is not just a recommendation, but a strict technical requirement.
Factors influencing the settling time of equipment
There is no single number that would suit absolutely everyone. The amount of time a refrigerator should sit idle depends on many variables. The first and most important factor is position during transportation. If you transported the unit strictly vertically, carefully installing it in the back of the truck, then the disturbance processes were minimal. In this case, the oil could only foam slightly, and it would take less time to calm down.
A completely different situation arises when large-sized equipment has to be transported lying down. This often happens when moving by car or in the absence of a freight elevator. In a horizontal position, oil is guaranteed to flow out of the compressor into the circuit pipes. It also matters which side the refrigerator was on. Manufacturers usually indicate that the unit should be placed only on a certain side (often the left, when viewed from the front, or the right - depending on the design) in order to minimize oil leakage from the compressor area.
The second critical factor is ambient temperature. If the move took place in winter, and the refrigerator was brought from the cold into a warm room, the problem of condensation and thermal expansion of materials is added to the problem of oil. A sharp temperature change is dangerous for plastic, rubber seals and electronic filling.
How long you need to wait: table and recommendations
So that you don’t have to guess, we have systematized the data on settling time depending on the transportation conditions. These recommendations are based on the experience of service centers and technical manuals of leading manufacturers of household appliances. Remember that it is better to keep the equipment turned off than to rush.
Below is a table that will help you navigate the time intervals. Please note that the given time frames are the minimum required. If you have the opportunity to wait longer, this will only benefit the device.
| Transportation conditions | Temperature conditions | Recommended settling time |
|---|---|---|
| Vertical, without strong shaking | Warm season / room | 2–4 hours |
| Lying on your side (up to 30 minutes on the road) | Warm season / room | 4–8 hours |
| Lying on your side (long-term transportation) | Warm season / room | 8–12 hours (preferably 24 hours) |
| Any position | Brought in from frost (below -5°C) | Minimum 24 hours |
| Strong shaking, impacts, overturning | Any conditions | 24 hours or more |
It is important to understand that inverter compressors, which are now installed in many models Bosch, Siemens i LG, are more sensitive to the quality of the lubricant and the presence of oil in the circuit. For them, meeting deadlines is critical. Older models with conventional motors may be a little more durable, but it’s also not worth risking their resource.
Features of winter transportation and frost drift
Transporting a refrigerator in winter is a separate category of risk. Here, the physical properties of materials at low temperatures are added to the mechanical problems. The plastic becomes brittle, the rubber seals become tanned and may lose elasticity, and the metal shrinks. If you suddenly bring a cold unit into a warm apartment, water will instantly appear on it.
This condensation is the main enemy of electrics. Water may flow inside the housing or get onto the contacts of the start relay, thermostat or control board. Turning on a wet device is guaranteed to result in a short circuit. In addition, ice may form inside the thermal insulation and in the channels, which, when expanded, can damage the thin tubes of the evaporator.
⚠️ Attention: It is strictly forbidden to speed up the warming process using heaters, hair dryers or heat guns. Sudden heating will lead to deformation of plastic parts and disruption of the geometry of the chambers.
The correct algorithm of actions when moving in winter is as follows: bring in the refrigerator without unpacking it completely (so that it warms up more slowly), and leave it in the corridor or hallway. Do not plug it in for at least 24 hours. During this time, it will not only warm up to room temperature, but all the condensation will have time to evaporate.
What to do with the packaging in winter?
Leave the cardboard and plastic on the refrigerator until completely warmed up. The packaging will create the effect of a thermos, slow down heating and prevent the formation of condensation on the very surface of the case. Remove the packaging only after the equipment has been kept warm for several hours.
Algorithm of actions: preparation for the first start
The required time has passed, the refrigerator has settled, warmed up and is ready for use. However, simply plugging a plug into a socket is not everything. There is a correct procedure that will help you avoid mistakes. First you need to remove all shipping packaging, tape and fixing elements. Pay special attention to the internal fastenings: some models come with fixed shelves or a compressor (although the latter is rare in household models).
Next, a visual inspection should be carried out. Check the integrity of the housing, make sure that the doors close tightly and that the seals are not kinked. If the refrigerator was transported lying down, it would not be amiss to gently (without fanaticism) rock it from side to side in a vertical position to help the oil flow down, although most of the time has done its job.
The next stage is connecting to the electrical network. It is important to use a separate grounded outlet. It is not recommended to use extension cords or tees as the compressor inrush currents may be high. After turning on, let the refrigerator run empty for 1-2 hours. During this time, it will reach the required temperature, and the automation will turn off the motor.
☑️ Preparation for the first start
Frequent errors and signs of malfunction after switching on
Even if all the rules are followed, nuances may arise after transportation. One of the common mistakes is loading products immediately after switching on. Warm food will put a huge strain on the compressor, which is already under stress after moving. Load cameras gradually, in small portions.
Also, users often ignore the first sounds of operation. Humming, gurgling, clicking - this may be the norm for some models, especially with the system No Frost. However, if you hear a loud metallic clanging, knocking or squealing sound, unplug the appliance immediately. This may indicate that the compressor is running without oil or a valve has failed.
Another sign of trouble is that the refrigerator works, but does not cool, or freezes too much, turning food into ice. This may indicate a freon leak (if the tubes were damaged due to careless loading) or a thermostat malfunction. In such cases, self-repair will not help, you need to call a specialist.
⚠️ Attention: If, after turning on, the refrigerator makes loud extraneous sounds (knocking, grinding), do not wait for “grinding in”. Unplug it immediately. Further operation in this mode will destroy the compressor in a matter of minutes.
Questions and answers (FAQ)
Is it possible to transport a refrigerator at a temperature of -20°C?
Technically it is possible, but with great caution. The main danger is not in work, but in drifting into heat. After such transportation, the settling time should be at least 24-36 hours. There is also a high risk of damage to plastic elements and seals due to temperature changes.
What happens if I turn on the refrigerator 1 hour after transporting it lying down?
Most likely, nothing will happen to it instantly, but the life of the compressor will be significantly reduced. The oil might not have time to return to the crankcase, and the first minutes of operation will pass in oil starvation mode. In the worst case, a water hammer will occur and the compressor will jam.
Is it necessary to defrost the refrigerator before transportation?
Yes, definitely. There should be no ice, water or food in the chamber. Excess moisture from tilting can get into electrical circuits or water drainage systems, causing corrosion or a short circuit. It is also better to secure the doors with tape so that they do not swing open.
Why does the refrigerator not turn off for a long time after transportation?
In the first hours of operation, this is normal. The unit must cool the entire volume of the chambers and gain temperature. If it works for more than 5-6 hours without stopping and does not freeze, this is a sign of a malfunction (freon leak, compressor or thermostat failure).
Is it possible to transport a refrigerator in the trunk of a car?
It is possible, but only lying down. In this case, it is extremely important to place it on the correct side (indicated in the instructions, usually back down or on the left side) and carry it very carefully. In this case, the settling time should be maximum - at least 12-24 hours.
