Transporting large household appliances is always stressful not only for the owners, but also for the equipment itself. Vibration, body tilts, temperature changes and sudden jerks during loading can seriously disrupt the operation of internal components, especially the compressor and refrigerant circulation system. That is why the question of how long it takes to turn on the refrigerator after transportation is critical for the longevity of the unit.
Many people mistakenly believe that it is enough to simply deliver the device to the kitchen, remove the packaging and immediately plug the cord into an outlet. However oil in the compressor, which is normally located in the crankcase, during transportation (especially in a lying position) could flow into the circuits of the cooling system. If you start the engine immediately, it will run dry, which will lead to rapid wear or immediate breakdown.
In this article we will analyze in detail the waiting time intervals, depending on the position of the equipment during transportation, and describe the algorithm of actions before the first start. Proper preparation is a guarantee that your new Liebherr, Bosch or any other brand will last the period stated by the manufacturer without costly repairs.
Why you can’t turn on the equipment right away
The main reason for the need to wait lies in the design of the compressor. This is the heart of the refrigeration unit, where oil performs the function of lubricating and sealing gaps between moving parts. When the housing shakes and tilts during a move, the oil inevitably leaves the place allocated for it and enters the pipelines.
If you turn on the unit before the oil returns by gravity to the compressor crankcase, the device will begin to operate with increased friction. This can lead to jamming of the piston group or valves. In addition, a so-called oil sealmay form in the refrigerant circulation system, which prevents the normal movement of freon.
⚠️ Attention: An attempt to start the compressor with oil in the circuit can cause water hammer, which is fatal to the mechanical part of the engine. Repairing or replacing the compressor is often not economically feasible.
It is also important to consider the condition of electrical contacts and sensors. Sudden temperature changes (for example, moving from cold to warm) cause condensation to form inside the case and on electrical circuit boards. Turning on wet electronics under voltage is guaranteed to result in a short circuit.
Factors influencing settling time
The time that the refrigerator must stand before turning on is not a fixed constant for all models. It directly depends on transportation conditions and ambient temperature conditions. The main factors are the position of the housing and the season of the year.
When transported in a vertical position, the risk of oil spillage is minimal, but vibration could still agitate the contents of the compressor. In this case, minimal time is required for the fluid to calm down. If the equipment was transported lying down, the waiting time increases several times, since the oil could spread throughout the entire circuit of the evaporator and condenser.
The influence of temperature on the waiting time
If you brought the refrigerator in from the cold, the waiting time increases not only because of the oil, but also because of the need to warm up the plastic and rubber seals. Cold plastic becomes brittle, and rubber loses elasticity, which can lead to microcracks during the first expansion cycle.
Seasonality also plays a role. In winter, when equipment is brought from the street, where the temperature is below zero, into a warm room, it is necessary to wait not only for the oil to drain, but also for the temperatures to equalize. The condensation formed on the parts must completely evaporate.
The table below systematizes the recommended settling time depending on the conditions:
| Transportation conditions | Season | Recommended time | Cause |
|---|---|---|---|
| Vertical | Summer | 2–4 hours | Oil drainage, refrigerant calming |
| Vertical | Winter | 4–6 hours | Drying of condensate, warming up the oil |
| Horizontal (lying down) | Summer | 8–12 hours | Complete return of oil to the crankcase |
| Horizontal (lying) | Winter | 12–24 hours | Complex recovery (oil + condensate) |
Installation rules after delivery
Before thinking about the turn-on time, you must install the unit correctly. The floor on which the refrigerator is placed must be perfectly level. Distortions lead to improper operation of the door (it may open on its own or not close tightly) and increased compressor noise.
Use a building level to check the horizontal position. Adjustment is carried out by twisting or unscrewing the front support legs. Rear wheels or the supports are usually not adjustable, but must be firmly on the floor. After leveling, the refrigerator should stand steadily, not wobbling when pressed lightly.
It is important to ensure the correct thermal conditions. Do not place equipment close to a wall or furniture. The rear grille (condenser) must have free air access for heat transfer. The minimum distance from the back wall to the wall of the room should be at least 5–7 cm, and on the sides - about 2–3 cm.
☑️ Checking the installation
If you plan to install it in a niche or kitchen unit in the kitchen, make sure that ventilation is provided for by the design of the furniture. Built-in models Indesit or Atlant have their own heat dissipation features, ignoring which will lead to overheating and increased power consumption.
Preparation for the first start
After the required settling time has passed, you cannot simply click switch. A number of preparatory manipulations are required. First of all, remove all transport elements: tape, foam corners, protective film. Pay special attention to internal fastenings.
Often inside the chamber there are shelves and drawers secured with tape or foam inserts so that they do not hit the walls when shaking. They need to be removed. Also check if there are instructions or silica gel packets inside.
The next step is sanitization. Even if the refrigerator is new, there may be a smell of factory grease, plastic or packaging inside. Prepare a weak solution of baking soda (1 tablespoon per liter of water) or use a special detergent for washing household appliances.
⚠️ Attention: It is strictly prohibited to use abrasive powders, aggressive solvents or chlorine-containing products to wash internal plastic surfaces. This can damage the coating and make the plastic brittle.
Wipe all shelves, walls and doors thoroughly, then wipe dry with a clean rag. Leave the doors open for another 30–60 minutes to completely remove the smell of detergent and plastic. Only after this you can start connecting.
First start-up algorithm
The first start-up process should be idle. This means that you cannot immediately load food into the chambers. The compressor needs time to create the required temperature inside the empty volume. If you immediately fill the refrigerator with food, the load on the engine will be critical.
Plug the cord into the outlet. Make sure the outlet matches the refrigerator's power rating and is grounded. Do not use extension cords and tees unless absolutely necessary - direct contact with the network is more reliable. Set the temperature regulator to the middle position (usually 2-3 divisions or mode Eco).
After turning on, listen to the operation of the unit. At first, a quiet hum may be heard, then a characteristic gurgling or hissing sound - this is normal, the refrigerant begins to circulate. After some time (from 15 minutes to an hour, depending on the model), the compressor should turn off on its own when the sensor detects that the set temperature has been reached.
The first cooling cycle may last longer than usual. If the refrigerator does not turn off for more than 2-3 hours in a row, this is a cause for concern, but for the first time this is possible if the room is very hot. However, if after 4-5 hours of operation it does not become cold inside, and the compressor continues to hum without interruption, there may be a freon leak during transportation.
What do the sounds mean when you first start?
Clicks - the operation of the thermostat or the start relay. Gurgling is the movement of freon through the tubes. Hissing is a normal process in No Frost systems. The creaking may be caused by the expansion of the plastic, but if it does not go away within a day, diagnostics are needed.
Frequent errors during operation after moving
Statistics of service centers show that a significant portion of breakdowns occur in the first weeks after purchase or moving due to banal non-compliance with instructions. One of the main mistakes is ignoring the standing time.
Owners often think: “They brought it standing up, so you can turn it on.” But if the road was long and bumpy, the oil could still mix with the refrigerant. Another mistake is setting the maximum cooling power immediately after turning on in the hope of freezing food faster.
Also, users often forget to check the rubber seals on the doors. They may have become dislodged or become dirty during transportation. A loose fit of the door will cause the compressor to work without stopping, trying to compensate for heat loss, which will quickly disable it.
⚠️ Attention: If after transportation you notice mechanical damage to the case, dents on the radiator grille or traces of oily liquid under the refrigerator, it is prohibited to turn it on! Contact the service center to diagnose the tightness of the circuit.
Remember that warranty period does not always cover damage caused by improper transportation and startup. An examination will easily determine that the compressor burned out due to operation without oil or water hammer.
What to do if the refrigerator was turned on immediately after transportation?
If you accidentally turned on the unit right away, immediately turn it off from the network. Let it sit turned off for at least 6-8 hours (preferably 24 hours) to ensure the oil returns to the crankcase. If, after turning it on again, the refrigerator operates normally, cools and does not make any unusual knocks, you are lucky. If extraneous sounds appear or cooling stops, call a specialist.
Is it possible to transport a refrigerator in cold weather?
You can transport it, but you absolutely cannot turn it on right away. At low temperatures (below -5°C) oil thickens and loses its properties. Starting a cold compressor abruptly will cause it to break. After being brought into a warm place, the refrigerator should warm up at room temperature for at least 6–8 hours, or better yet, a day, before you try to start it.
How can you tell that the compressor has burned out?
Main signs: the refrigerator hums, but does not cool; the compressor turns on for a few seconds, clicks and turns off; the compressor housing does not heat up or, conversely, overheats to the point of redness; there is a smell of burnt wiring. In such cases, independent repair is impossible; replacement of the unit is required.
Is it necessary to defrost the refrigerator before transportation?
Yes, definitely. The presence of ice and water inside the chambers during transportation is unacceptable. Water can flow into service openings, damage the insulation, or freeze when conditions change and damage the plastic. In addition, a full refrigerator is heavier, which increases the risk of damage to the shelves when shaking.
How long before you can load food?
After turning it on for the first time and reaching operating temperature (usually it takes 2-4 hours for an empty refrigerator), you can start loading. Do not fill the chambers completely at once. Load food in small portions at intervals of 1-2 hours so as not to create a sharp thermal load on the compressor.
