It would seem that it could be simpler than install a new refrigerator in the kitchen? However, it is the neglect of basic installation rules that often causes hum, vibration and even breakdown of the compressor after several months of operation. Proper installation of the refrigerator is not just an aesthetic issue, but a necessity that prolongs the life of an expensive unit. If the case is skewed, the doors may not close tightly, which will lead to freezing of the evaporator and increased energy consumption.
Many owners of household appliances make the mistake of relying solely on the levelness of the floor in a new building or an old house. In practice, even minimal misalignment, invisible to the eye, creates excessive load on the frame and compressor. In this article we will look at why a specific one is needed, how to use a building level and why plastic stands under the wheels must be disposed of immediately after delivery. tilting the body back, how to use a building level and why plastic wheel stands must be disposed of immediately upon delivery.
The adjustment process takes only 15-20 minutes, but requires care and the availability of a simple tool. Ignoring this step may void the manufacturer's warranty if the failure is due to improper use. Let's figure out how to align the equipment perfectly so that it works silently and efficiently for many years.
Why do you need to level the refrigerator strictly?
The main reason why it is necessary to level the case lies in the design of the automatic defrosting system. In modern models with a function No Frost or a drip system, condensate should flow into a special gutter located on the back wall inside the chamber. If the refrigerator is tilted to the left or right, water will accumulate in the corners of the shelves or, worse, flow out through the lower door seal.
The second critical point is the operation of the compressor and hanging elements. The vibration from the motor, transmitted to the skewed body, increases significantly. This leads to unpleasant humming, rattling of tubes and loosening of fasteners. In addition, a skewed door creates additional resistance when opening and closing, which wears out the hinges faster and can disrupt the tight fit of the rubber seal sealing gum.
⚠️ Attention: If you notice that the refrigerator door opens by itself or, conversely, does not fully adhere to the body without strong pressure, in 90% of cases the problem is precisely in violation of the horizontal position of the unit.
There is a common misconception that equipment needs to be set perfectly to zero on all axes. In fact, for the self-closing door system to work correctly, it is necessary to create a small, barely noticeable tilt of the body backwards. This ensures gravitational closing of the sash if you left it open at an angle of less than 45 degrees.
Necessary tools for adjusting the supports
Before you start setting, you need to prepare a minimum set of tools. In most cases, what is available in every home is sufficient, but older or heavier models may require specific adaptations. The main task is to gain access to the adjusting screws, which are usually hidden under decorative panels or located in the lower part of the case.
For work you will need:
- 🛠️ Building level — preferably a bubble one with a length of 40 cm in order to cover a large area and see the slightest deviations.
- 🔧 An adjustable wrench or open-end wrenches —the size depends on the model, often a 10, 12 or 14 mm wrench is required.
- 📏 Ruler or tape measure —to check the height of the front legs relative to the rear ones.
- 🧤 Thick gloves —the bottom of the refrigerator may be sharp or dirty after transportation.
In some modern models, such as Liebherr or Bosch, adjustment can be made without tools, directly by hand, if knurled plastic screws are used. However, for heavy two-chamber models weighing more than 80 kg, it is better to use a wrench to break off rusted or tightly clamped threads.
⚠️ Attention: Before starting work, be sure to disconnect the refrigerator from the power supply! You will be working in close proximity to metal parts and possible condensation, which creates a risk of electric shock.
Step-by-step instructions: how to level a refrigerator
The installation process begins with freeing up space. Move the unit away from the wall to gain access to all four corners. Remove the shipping supports if they are not already removed. Often there are plastic transport shoes under the front legs - they must be removed, since they have a fixed height and do not allow adjustment.
Next follow the following algorithm:
- Put a building level on the top cover of the refrigerator parallel to the front wall.
- Check the position of the transverse axis (from left to right). The bubble must be located strictly between the marks.
- If there is a deviation, rotate the adjusting screws of the front legs. Typically, the right leg rotates clockwise for lifting and counterclockwise for lowering.
- After leveling across, rearrange the level so that it shows the longitudinal axis (front-to-back).
- It is important here to achieve a slight tilt back. The front part should be higher than the back by about 1-2 centimeters.
⚠️ Attention: Do not unscrew the front supports too much. If you unscrew them to the maximum height, the threaded connection may become unstable, and the refrigerator will wobble when loaded with food.
After mechanical adjustment, be sure to check the result. A door open 30–40 degrees should close smoothly and confidently on its own. If this does not happen, add another half turn to the front screws. Make sure that all four legs (or wheels) are firmly in contact with the floor - wobbling is unacceptable.
☑️ Checking the installation
Features of installation on wheels and screw supports
The design of the supports may vary significantly depending on the brand and class of equipment. Budget models often come with simple plastic screw feet that are easy to adjust but can slip on smooth tile floors. In this case, you can place small pieces of rubber or linoleum under them to increase grip.
Models of the middle and premium segment, for example LG or Samsung, are often equipped with a combined system: stationary supports are installed at the rear, and swivel wheels with a locking function are installed at the front. In such cases, first set the height of the rear supports, and then adjust the height of the front wheels so that they only lightly touch the floor or lift the body for movement.
It is important to understand the difference between transport wheels and working supports:
- 🔄 Transport wheels —are intended only for moving an empty refrigerator. In working condition, the body should rest on screw legs.
- ⚙️ Working supports - carry the main load and dampen vibration. They must be unscrewed until they are in tight contact with the floor.
- 🔒 Clamps — on some models there is a locking mechanism that prevents spontaneous rotation of the legs.
Typical installation errors and their consequences
Even following the instructions, inexperienced users often make mistakes that nullify all efforts. The most common of them is installing equipment on a soft base, carpet or thick linoleum without a hard backing. Over time, the legs push through the coating, and the level gets lost, which leads to the doors being skewed.
Another mistake is ignoring ventilation gaps. Having set the level, many people move the refrigerator close to the wall. This disrupts the air circulation around the condenser (black grille at the back), which causes the compressor to work harder. The minimum distance to the rear wall should be 5–10 cm, to the side walls - 5 cm.
Table of common problems with incorrect installation:
| Symptom | Probable cause | Solution |
|---|---|---|
| The door does not fit | The body is skewed towards the hinges | Raise the opposite front leg |
| Strong vibration | One of the legs does not touch the floor | Tighten the supports to a stable position |
| Puddle inside the chamber | No tilt back | Unscrew the front legs higher than the rear ones |
| Compressor humming | Touching of the tubes on the body or wall | Move the equipment aside, straighten the tubes |
The influence of the floor covering on stability
The type of floor plays a critical role in the stability of the refrigerator. On wooden floors in old houses ("Khrushchev", "Stalin") the effect of "walking" of the floor is often encountered. In such cases, a heavy refrigerator filled with food can create a stress point, deforming the cover. Here it is important not only to set the level, but also to distribute the load, perhaps using a plywood or chipboard backing.
On ceramic tiles or porcelain stoneware, the main problem is slipping. If the floor is very smooth, the vibration of the compressor may cause the refrigerator to slowly move from its position. The feet should be adjusted to ensure maximum friction. Sometimes it is useful to wipe the contact points between the supports and the floor with a degreaser to remove the grease film.
If you have a “warm floor” system, keep in mind that constant heating from below can negatively affect the operation of temperature sensors and thermal insulation of the bottom. In such cases, manufacturers recommend installing the equipment on a slight elevation or using a thermally insulating stand, which also requires re-checking the level.
What to do if the floor is crooked?
If the difference in floor heights is too large and the length of the adjusting screws is not enough, use metal pads under the legs. Do not use wooden blocks or cardboard under any circumstances - they will dry out or get wet over time, and the refrigerator will warp again. Stainless steel or thick rubber plates are ideal.
Frequently asked questions (FAQ)
Do you need to remove food before leveling?
It is desirable, but not necessarily completely. An empty refrigerator is easier to move, but for fine tuning it is better to simulate the workload. If you are setting the level on an empty unit, after fully loading the products, check the position of the doors again - under the weight of the shelves, the body may be slightly deformed, and the adjustment will have to be corrected.
Is it possible to place the refrigerator on its side for adjustment?
It is strictly not recommended to place the refrigerator on its side, especially on the back wall, where the pipes and compressor are located. This may lead to oil leakage into the cooling circuit or damage to the thermal insulation. All work on adjusting the legs is carried out only in a vertical position.
How often do you need to check the level?
Once immediately after installation is enough. However, if you notice changes in the work (noise appears, the door no longer closes) or work was carried out in the house that could cause vibration in the floor (drilling, replacing pipes), the check should be repeated. Also, the level gets lost after the first defrosting, when water could escape from under the legs.
What to do if the adjusting screw is rusty and does not turn?
Do not use excessive force so as not to strip the thread. Try placing a few drops of penetrating lubricant (such as WD-40) on the threads and wait 10-15 minutes. If the screw is plastic and jammed, you can try to gently warm it up with a hairdryer (without overheating the plastic) so that it becomes more elastic.
