Transportation of large household goods equipment often becomes a real test for owners, especially when it comes to large units with the system No Frost. The situation when it is necessary to transport a refrigerator in a horizontal position arises when moving, buying used equipment, or delivering it from a store using personal transport. Many users fear that such a position will be fatal for expensive equipment, and these fears are well founded by the design features of modern models.
The main problem lies in the design of the compressor, where the oil is located, and the refrigerant circulation system. In a vertical position, all liquids are in strictly designated places, but when tilted or laid on their side, oil can flow into the cooling circuit, and the mechanical parts of the motor can shift. No Frost refrigerators are especially sensitive to such manipulations due to the presence of additional fans and a complex system of air ducts hidden in the walls of the case.
Nevertheless, transportation while lying down is possible if you follow a strict algorithm of actions and time intervals. Ignoring the preparation rules can lead to water hammer in the compressor when it is first turned on, which will cause the unit to fail instantly. In this article we will analyze the technical nuances that will help maintain the functionality of the equipment during horizontal transportation.
Design features of the No Frost system
The system No Frost (literally “without frost”) is fundamentally different from the classic drip defrosting by the presence of forced air circulation. Inside the case there are special fans that drive cold air through a system of hidden channels, evenly distributing the temperature throughout all chambers. This means that the internal structure of such a refrigerator is more complex and full of plastic elements, which can be damaged if improperly installed.
An important element is the evaporator, which is usually hidden behind the back panel in the freezer. When transporting lying down, excess pressure may be placed on this unit, especially if the refrigerator is old and the plastic has lost its elasticity. In addition, in models with Inverter Compressor (inverter compressor), the motor suspension may be more sensitive to lateral loads than in classic linear models.
Another critical point is the refrigerant supply pipes. In No Frost systems they are often made of aluminum or thin steel and located close to the surface of the housing. When transporting lying down, there is a high risk of deformation of the case, which can lead to pinching or rupture of thin-walled tubes. Therefore, external protection and correct orientation of the unit become critical.
- 🌀 Air circulation fans require reliable fixation so that the blades do not move when shaking.
- ❄️ Hidden air ducts in the walls can crack if the housing is skewed while moving.
- 🛢️ The compressor oil system in inverter models is less resistant to oil entering the circuit during a prolonged lying position.
Understanding these features helps to understand why manufacturers often insist on vertical transportation. However, if there is no alternative, knowledge of the device allows you to minimize risks. The main thing is to prevent mechanical damage to the internal partitions and displacement of heavy components.
Main risks during horizontal transportation
The greatest danger comes from oil ingress from the compressor to the freon circulation system. In working condition, the oil is located in the engine crankcase. When the refrigerator is placed on its side, the oil flows into the evaporator and condenser tubes under the influence of gravity. Upon subsequent startup, the compressor will try to compress the gaseous freon, but instead will receive liquid oil, which will lead to water hammer and destruction of the valve group.
The second serious risk is a violation of the tightness. When transported lying on an uneven surface or without proper shock absorption, the case may “lead.” The soldering areas of the tubes, especially in the compressor area, experience fracture stress. refrigerators with the No Frost system is characterized by the presence of many connections in hidden cavities, access to which is difficult, so even a microcrack can cause expensive repairs.
⚠️ Attention: It is strictly forbidden to place the refrigerator on the front door or on the rear grille (condenser). Laying on the door will lead to deformation of the hinges and disruption of the seal, and laying on the rear grille can damage the tubes and compressor, since they are not designed to support the weight of the entire body.
It is also worth considering the risk of damage to the insulation. The internal walls of the refrigerator are filled with polyurethane foam. With strong shaking or impacts in a horizontal position, micro-tears may occur in the insulation structure, which over time will lead to loss of cold and the formation of condensation inside the walls. This is especially true for older models, where the materials have already undergone natural aging.
Preparing the refrigerator for transportation
Successful transportation begins long before you pick up the cargo belt. The first and most important stage is complete defrosting. Even if your refrigerator is equipped with a No Frost system, moisture remains inside it in the form of condensation in trays and channels. It is necessary to turn off the unit from the network, empty it of food and leave the doors open for at least 24 hours.
After defrosting, you should thoroughly wash and, most importantly, dry all internal surfaces. Residual moisture during transportation in a horizontal position may spread over the electronic components or cause corrosion of metal elements. Pay special attention to the water collection tray above the compressor - it must be removed and secured separately or secured with tape so that it does not dangle.
Next you need to fix the moving parts. Refrigerator doors must be tightly closed and secured. To do this, use masking tape, special transport tape or soft belts. Adhesive tape It is not recommended to wrap directly on the glossy surface of the case; it is better to place paper under it or use stretch film so as not to damage the coating when removing.
☑️ Checklist for preparation for transportation
All removable elements - shelves, drawers, baskets, egg cups - must be removed. They are transported separately, wrapped in soft cloth or bubble wrap. If you leave the shelves inside, when shaking, they can break or damage the internal walls of the chamber, especially in the system No Frostwhere the plastic is more fragile due to the low operating temperature.
The technology of correct laying and fixing
The choice of the side on which the refrigerator will be laid is critical. The best option is to lay it on the side opposite the tube exit from the compressor. Usually the tubes come out from the left side (if you look at the refrigerator from the front), which means you need to place it on the right side. However, the design may differ among different manufacturers (LG, Samsung, Bosch, Indesit), so a visual inspection of the rear wall is required.
If it is impossible to determine the side of the tube exit, follow the general rule: lay it on its side, where the door handle is on top. This minimizes the risk of the door opening due to vibration. Under the refrigerator you must place a thick blanket, polystyrene foam or a thick layer of cardboard. This will create a buffer zone and protect the body from scratches and dents from uneven body floors.
| Element | Action | Risk if ignored |
|---|---|---|
| Compressor | Fix transportation bolts (if any) | Separation of suspension springs, noise, vibration |
| Doors | Wrap with stretch film in 3-4 layers | Opening of doors, broken hinges, breakage glass |
| Tubes | Make sure they do not touch the floor | Kink, rupture, freon leak |
| Housing | Protect with cardboard or a blanket | Dents, scratches, irregularities of geometry |
When securing in the back of a car or truck, use soft belts. Do not overtighten them so as not to deform the body, but also do not allow free movement. The refrigerator must stand (lie) stable, resting on the side or sides of other cargo. It is ideal if soft bags or boxes are placed nearby, which will take on the inertial loads during braking.
Settling time before switching on
The most critical stage after delivery is waiting. Many people make the mistake of turning on the refrigerator immediately after installation. This cannot be done. Any oil that has entered the cooling circuit during transport must drain completely back into the compressor crankcase under the influence of gravity. If you turn on the unit ahead of time, water hammer almost guaranteed.
There is a direct relationship between transportation time and settling time. If you transported the refrigerator lying down in warm weather in the summer, the process of oil spreading goes faster. In winter, especially if the equipment is frozen, the oil becomes thick and takes longer to return to its original position. In addition, a sharp temperature change can cause condensation to form on electronic boards.
The myth about vertical transportation
There is a common belief that if you transport a refrigerator while standing, you do not need to stand for it. This is not entirely true. When shaking in a vertical position, the oil can also foam and get into the tubes, so 2-4 hours of rest will not hurt even in this case.
The recommended holding time depends on the season and position during transportation:
- ☀️ Summer transportation (lying down): minimum 4-6 hours. Warm oil drains faster.
- ❄️ Winter transportation (lying down): minimum 12-24 hours. It takes time not only for the oil to drain, but also for warming up to room temperature to avoid condensation.
- ⬆️ Vertical transportation: 2-4 hours to stabilize the system.
Not hurry up. It’s better to lose a day of time than to buy a new compressor or a whole refrigerator. Plug in the device only after it has completely warmed up to room temperature and has been left alone for the required time.
Actions after installation in a new location
After the settling time has expired, do not rush to load the products. First, check the exterior of the unit for any damage incurred during travel. Make sure the level is correct using the adjustable feet. For correct operation of the system No Frost and proper closing of the doors, the refrigerator must stand strictly horizontally or with a slight slope back.
Plug in the empty refrigerator and let it work for 1-2 hours. During this time, it will gain temperature, and you can check the operation of the compressor and fans. listen to the sounds: there should be no extraneous knocking, humming or gurgling (except for short-term noise when starting). If everything is working properly, you can gradually load the food.
Pay attention to the operation of the defrost system. After a few hours (or after 8-12, depending on the settings), the first defrost cycle should go through. You may hear a slight hissing or crackling sound - this is normal, this is how the evaporator heater and mode switch work. If the cold does not appear within 24 hours or the “coat” is frozen, it means that a freon leak occurred during transportation or the capillary tube was clogged.
⚠️ Attention: If after turning on the refrigerator works, but does not freeze, or the compressor hums for 5-10 seconds and turns off with a click, immediately disconnect the device from the network. These are signs of water hammer or compressor wedge. Repeated starts can finally finish off the motor.
Common mistakes when transporting yourself
One of the most common mistakes is neglecting packaging. People often transport equipment “as is”, expecting it to be neat. However, even a small pebble that falls under the bottom during loading can push through the thermal insulation or damage the tube. Always use a backing.
The second mistake is fixing the doors with regular office tape. It cannot withstand the load and bursts on the way, the door opens slightly and breaks the glass or the handle breaks on the side of the car. Use only reinforced tape, stretch film or rope.
The third mistake concerns winter transportation. Having brought the frozen refrigerator into the warmth, it is immediately turned on. This causes condensation to form on the internal contacts and the control board, causing a short circuit. The electronics of modern No Frost models are very sensitive to moisture.
Ignoring the manufacturer's instructions is another path to problems. Some brands (for example Liebherr or Miele) may have specific shipping requirements for their models. Always look for a sticker on the back wall or in the product passport indicating the permissible tilt angles.
Is it possible to transport the No Frost refrigerator lying down in the winter?
It is possible, but with strict precautions. The main danger in winter is not only oil, but also condensation. After being brought into a warm room, the refrigerator must be left turned off for at least 24 hours to fully warm up and dry inside. Turning on a cold unit is guaranteed to lead to oxidation of the contacts.
What happens if you turn on the refrigerator immediately after transporting it lying down?
There is a high probability of water hammer. The oil that gets into the circuit will not have time to drain, and the compressor will try to compress the liquid. This leads to destruction of valves, breakage of connecting rods or jamming of the piston group. Repair in this case is often unprofitable.
Which side is better to lay it on: left or right?
It is recommended to lay it on the side opposite to the outlet of the tubes from the compressor. Usually this is the right side (when viewed from the front), but the design is different for everyone. Look at the back: where the copper/aluminum tubes come out - that side should be on top. If the pipes are in the middle or on both sides, choose the side where the door handle is on top.
Do you need to remove the doors during transportation?
It is not necessary to remove the doors if you secure them securely with tape or film. Removing the doors is only necessary if the refrigerator does not fit through the doorway. If you have removed the doors, be sure to number the hinges and mating parts so that you don’t mix up the sides during assembly.
How can you tell if the compressor is damaged during transportation?
When turned on, a working compressor emits a smooth hum. A damaged one may knock loudly, hum intermittently, vibrate strongly, or turn on for a few seconds and turn off with a relay click. Also a sign may be a lack of cold when the engine is running.
