It would seem that it could be easier than just bringing and installing the refrigerator in the kitchen? However, it is incorrect installation that often causes increased noise, vibration and even failure of an expensive compressor in the first years of operation. Many users mistakenly believe that the main thing is that the device should stand level, not wobble, and fit into the interior, ignoring the technical requirements of manufacturers.
In fact, horizontal plane and the correct angle of the housing are critical parameters for the correct operation of the refrigerant circulation system. If you ignore this installation step, you risk encountering a situation where the oil will not return to the compressor, and the doors will no longer close tightly on their own. In this article we will look at all the nuances of setting up the support legs and using a building level.
Why is it necessary to set the refrigerator strictly according to the level
The main reason why manufacturers of household appliances insist on ideal installation lies in the physics of operation compressor-condensing unit. Not only gaseous and liquid freon circulates inside the system, but also a special oil that lubricates the rubbing parts of the engine. If the housing is skewed, oil may accumulate in one of the circuits instead of returning back to the compressor crankcase.
The second important aspect is the tightness of the chambers. The doors of modern refrigerators are often equipped with magnetic seals, which must adhere to the body evenly along the entire perimeter. When skewed in any direction, a gap is formed through which warm air will penetrate into the chamber. This forces thermostat to work more intensely, increasing energy consumption and wear of parts.
⚠️ Attention: Constant operation of the compressor at maximum load due to chamber leakage caused by misalignment can reduce the service life of the refrigerator by 30-40%.
In addition, a correctly set level directly affects acoustic comfort. Uneven distribution of weight on the supports leads to resonance of the body and floor, which causes hum and rattling, which cannot be eliminated by any soundproofing materials.
Necessary tools for precise installation
Before starting the adjustment, you need to prepare a minimum set of tools. Without them, it will not be possible to perform the work efficiently, since it is impossible to determine microscopic deviations “by eye”. The main tool is construction levelwhich must be in good working order and have clear risks.
To rotate the adjusting screws, various devices may be required depending on the model of your refrigerator. In some cases, manual effort is enough, but often you need adjustable wrench or a set of open-end wrenches. It would also be a good idea to have a rag under the roll so as not to scratch the floor or decorative elements of the device.
- 🛠️ Construction level (bubble) with a length of 40 cm - for accurate measurement of the plane.
- 🔧 Adjustable wrench or set keys - for rotating threaded supports.
- 📏 Tape measure - for checking distances to walls and furniture.
- 🧤 Work gloves - to protect your hands from sharp edges and dirt.
If you do not have a professional construction level, you can use a laser level or even a specialized application in smartphone, although their accuracy may be inferior to a classic instrument. It is important that the surface on which you place the level is clean and dry.
Technology for adjusting the support legs
The adjustment process begins with studying the design of the bottom of the refrigerator. Most models have two front adjustable feet and two rear ones, which are often fixed wheels or simple plastic stands. Adjustment is carried out by screwing or unscrewing the front legs.
First, you need to slightly tilt the refrigerator back (a second person will help with this) to release the front supports from the load. Then, by rotating the screws, ensure that the device is stable and does not wobble from side to side. After this, check the level position.
☑️ Algorithm for adjusting the legs
There is an important nuance: the refrigerator should not just stand level, but with a slight slope back. This is necessary so that the doors close independently under the influence of gravity. If the device is positioned perfectly horizontally, the door may remain slightly open if it is released.
| Parameter | Value | Impact on operation |
|---|---|---|
| Forward tilt | Unacceptable | The door does not close, the cold is coming out |
| Ideal horizon | 0 degrees | The door stands still, loose clamping is possible |
| Tilt back | 2-3 degrees | Door self-closing, proper oil circulation |
| Disk to the left/right | Unacceptable | Noise, vibration, compressor wear |
After adjustment, be sure to check the stability. Try shaking the refrigerator slightly. If it stands “dead” and does not play, it means that all four support points are used correctly. If you feel swaying, repeat the procedure of twisting the legs.
Is tilting back necessary and why is it important?
Many users are surprised to learn that the requirement to “set it level” actually implies the creation of an artificial slope. Why is this so? Design engineers calculate the geometry of doors and hinges in such a way that when closed, the center of gravity of the door moves inside the chamber.
This provides two advantages. Firstly, you don’t need to control whether you slammed the door all the way - it will “close” itself with a magnet and gravity. Secondly, this guarantees a tight fit sealing rubber along the entire contour, which is critical for energy saving.
⚠️ Attention: If your refrigerator is on a perfectly flat floor, but the door does not close itself when opened 30-40 degrees, This means that the front legs need to be unscrewed even more in order to increase the angle of inclination of the body back.
However, do not overdo it. Too large an angle of inclination can cause products on the shelves to begin to “roll” towards the back wall, and in some models this can disrupt the flow of condensate into the drainage system. The optimal angle is one at which the door closes itself, but the shelves inside remain horizontal.
What to do if the floor is curved?
If the floor in the room has a strong slope or holes, using only standard refrigerator legs may not be sufficient. In such cases, it is recommended to place solid, non-moisture-absorbing pads under the legs (for example, pieces of linoleum or special anti-vibration stands) to level the base, and only then adjust with screws.
Common installation errors
Even following the instructions, inexperienced craftsmen often make mistakes that nullify all efforts. One of the most common is ignoring the condition of the floor. If the linoleum is swollen and the tiles have height differences, no amount of adjustment of the legs will help achieve a stable result.
Another mistake is the use of soft pads. Some try to level the height using wooden blocks, cardboard or rags. Over time, such materials are compressed under a weight of 60-80 kg, and the refrigerator warps again. In addition, wood and cardboard are afraid of moisture, which can form at the bottom of the body.
- 🚫 Installation on a soft base (carpets, mats) without a hard backing.
- 🚫 Using only two front supports without support on the rear wheels.
- 🚫 Excessive twisting legs, which leads to deformation of the bottom.
- 🚫 Ignoring gaps to walls and furniture, which interferes with ventilation.
They also often forget about vibration isolation. If the floor is wooden or has resonating properties, even a perfectly positioned refrigerator can hum. In such cases, it is recommended to use special anti-vibration pads under the legs that dampen vibrations.
Checking the result and testing
After the adjustment is completed, it is necessary to carry out a final check. Don't rush to load the refrigerator with food. First, let it stand in an upright position for at least 2-4 hours (especially if it was transported lying down) so that the oil flows into the compressor.
Then turn on the device and listen. During the first few minutes of operation, the compressor may be louder than usual - this is normal. But after 10-15 minutes the noise should stabilize. Run your hand over the body: there should be no strong vibration.
Check the operation of the doors. Open the refrigerator door to 45 degrees and release. It should close smoothly but confidently on its own. Check the same with the freezer if it has a separate door. If the door stands still or opens even wider, the adjustment must be repeated.
Pay attention to the gaps. There should be a distance of at least 5-7 cm between the back wall of the refrigerator and the kitchen wall for free air circulation. This ensures effective heat exchange of the condenser, which is often located at the back or on the sides.
Is it possible to install a refrigerator on a heated floor?
Installing a refrigerator on a "warm floor" system is not recommended by manufacturers. Heating the bottom of the housing causes the compressor to work harder, trying to compensate for the heat coming from below. This leads to excessive energy consumption and a reduction in the resource of the unit. If there is no alternative, make sure that the heated floor in the installation area is turned off or has a minimum temperature.
What to do if one leg is broken or lost?
Do not try to replace the standard plastic or metal support with a wooden block “forever”. It is better to contact the service center of the manufacturer of your model (Bosch, LG, Samsung, Indesit etc.) to order original spare parts. Universal adjustable furniture supports may not fit the thread or diameter, which will lead to misalignment.
Do you need to remove the shelves during installation?
When unscrewing the legs itself, it is not necessary to remove the shelves. However, if you are doing a full stability and tilt test, it is best to empty the chambers of food and remove the glass shelves. This will facilitate the design and protect the glass from falling if the body is sharply tilted during adjustment.
