The problem that many owners of new household appliances face after delivery often causes confusion: there are simply no supports in the back of the unit, and the front screws are tightened all the way or, conversely, dangling. The lack of rear adjustable legs is not a manufacturing defect or a mistake made by the assemblers, but rather the majority of modern refrigerator models. Understanding the physics of the compressor and the condensate removal system will help you avoid fatal installation errors. specific design feature most modern refrigerator models. Understanding the physics of the compressor and condensate removal system will help you avoid fatal installation errors.
Incorrect installation can lead to the fact that refrigerator compartment no longer closes tightly, and the doors begin to open spontaneously. Moreover, the angle of the housing is critical for proper drainage of melt water into the evaporator. If you ignore this nuance, a puddle will soon appear on the floor, and an unpleasant odor and mold will appear inside.
In this article we will look at why manufacturers save on rear supports, how to use a building level for fine adjustments, and what available means can be a temporary solution. Horizontal plane floors in apartment is a relative concept, so it is absolutely impossible to rely only on a visual assessment. Proper adjustment of the front supports will compensate for any unevenness of the floor covering.
Why the rear legs are often missing: engineering design
Many users mistakenly believe that the refrigerator should stand strictly horizontally in all planes, resting on four points. However, design engineers have long come to the conclusion that for proper operation of the unit it is necessary a certain tilt back. That is why the rear part of the case is often devoid of adjustable screws and rests directly on the lower metal frame or decorative plinth.
This design ensures that the doors close naturally under the influence of gravity. If the refrigerator stood perfectly level or tilted forward, the doors would open by themselves, disrupting the temperature regime and increasing the load on compressor. The absence of rear legs also simplifies the factory assembly process and reduces the cost of the final product, since there is no need for a complex system for balancing four supports.
⚠️ Attention: An attempt to independently screw the rear legs by drilling the bottom may damage the freon pipe channels or compromise the integrity of the thermal insulation, which will lead to loss guarantees.
In addition, the rear wall often has protruding elements, such as a condenser or compressor compartment, which physically do not allow additional supports to be installed there without changing the entire geometry of the case. Therefore, all responsibility for alignment falls on front adjusting bolts, which are the installer's main tool.
Necessary tools for self-installation
Before you start adjusting, you need to prepare a minimum set of tools. The main device here is the construction bubble level. It is advisable that its length be at least 40-50 cm, since short school rulers with a level give too large an error on the base area of the refrigerator.
To rotate the adjusting screws you will need a wrench of the appropriate size, usually a 10, 12 or 14 mm wrench. Some models, for example, from the brand Indesit or Atlantmay require an open-end wrench, while for Liebherr or Bosch a head with a crank is often used. Also, a tape measure for checking diagonals and gaps will not be superfluous.
- 🛠️ Construction level (bubble or laser) for checking planes.
- 🔧 An adjustable or open-end wrench for rotating the support screws.
- 📏 Tape measure for measuring the distance to walls and furniture.
- 🧹 Rags for cleaning the floor under the unit before installation.
If the floor in the room is slippery (ceramic tiles, laminate), it is recommended to prepare special pads for the legs in advance. They will prevent unwanted movement of the heavy unit during operation, especially if there are children or pets in the house who could accidentally touch the body.
Step-by-step instructions: how to set the angle tilt
The leveling process begins with freeing up the space around the refrigerator. You need to provide access to all four corners of the base. First of all, check the current position of the doors: if they open slightly on their own when you release them after opening 45 degrees, it means that the tilt is insufficient or not at all.
Find the adjustment bolts in the front lower part of the body. They can be hidden behind a decorative panel (base), which must be carefully removed. Rotating the bolt clockwise leads to lifting the angle, and counterclockwise leads to lowering. Your task is to unscrew the front legs so that the back of the body is lower than the front by about 1-2 degrees.
☑️ Algorithm for adjusting the legs
After the initial setup, be sure to check the stability. The refrigerator should not wobble when you lightly press the top corner. If there is play, it means that one of the front legs is twisted more than the others, and the body rests on only three points. In this case, it is necessary to adjust the height of the screws, ensuring a tight fit of all supports.
| Symptom | Probable cause | Action |
|---|---|---|
| The door does not close itself | Insufficient tilt back | Unscrew the front legs higher |
| The refrigerator is wobbly | Different heights of the front supports | Align the height of the screws |
| Strong vibration | Legs do not touch the floor | Lower the screws all the way |
| Leak inside the chamber | No back tilt | Check the level and angle |
Give let the compressor cool down (if it was running) and check the final result after 15-20 minutes. Vibrations during motor operation may slightly change the position of the screws if they were not tightened with a locking nut (lock nut), which is present in some models.
The problem of unauthorized opening of doors
One of the most common complaints from users is that the refrigerator door does not stay closed. This is a direct consequence of a violation of the installation geometry. The rubber seal around the perimeter of the door is designed to ensure tightness only with a certain amount of pressure. If the body is skewed, the tightness of the fit is broken.
To fix the problem, it is necessary to increase the tilt of the body back. To do this you should increase the height of the front supports. In some models, such as Samsung or LG, the front legs have threads with a large pitch, which allows you to quickly change the height, but requires precision so as not to warp the door diagonally.
⚠️ Caution: Excessive tilt back (more than 3-4 degrees) can cause oil to leak from the compressor into the refrigerant circuit, which can result in costly system repairs.
If, after adjusting the legs, the door still does not fit tightly, the problem may lie not in the installation, but in the condition of the seal or hinges itself. However, in 90% of cases, during a new installation, it is enough to simply align front screwsso that gravity begins to work for you, slamming the door tightly.
What to do if the thread on the leg is broken?
If the plastic or metal thread of the support damaged, do not try to fix it with glue or tape under load. It is better to order an original spare part from the manufacturer or use a temporary wooden stand of the required thickness until a replacement arrives.
Eliminating noise and vibration during operation
Humming and rattling are frequent companions of an incorrectly installed refrigerator. If the housing is skewed, vibrations from the operating compressor are transmitted to the floor and amplified by resonance. In addition, if one of the legs does not touch the floor, a characteristic knock occurs, which can be annoying at night.
For diagnostics, run your hand over the body while the motor is running. If you feel strong vibration, check that all feet are firmly on the surface. Sometimes it is enough to tighten the screw half a turn to remove the backlash. In models with the system No Frost additional noise can be created by the fan if the case is skewed so much that the alignment of the internal elements is disrupted.
- 🔊 Check that the back wall of the refrigerator does not touch the battery or furniture.
- 🔊 Make sure that glass shelves or glass shelves inside the chambers do not vibrate bottles.
- 🔊 Inspect the compressor compartment: the tubes should not touch each other.
If the floor is very smooth and the refrigerator is heavy, it may “run away” or shift from vibration. In this case, it is recommended to use special anti-vibration pads under the feet. They not only fix the position, but also dampen high-frequency vibrations, making the operation of the equipment almost silent.
Features of installation on different types of coatings
Type floor covering dictates its operating conditions. On soft surfaces such as linoleum or carpet, the legs can be pressed down over time, changing the angle of inclination. Owners of such floors are recommended to periodically (every six months) check the level and, if necessary, tighten the supports.
On hard surfaces such as tiles or porcelain stoneware, the main danger is slipping. Here it is important not only to level the refrigerator, but also to secure it. Some models are equipped with anti-slip pads on the legs, but if they are not, you can use pieces of rubber or special mats.
If you install the equipment on a heated floor, make sure that there is a gap between the bottom of the refrigerator and the surface for air circulation. The absence of rear legs is even beneficial here, since the case often has special ribs or a raised frame, but it is better to double-check the documentation for the specific model Beko or Haier.
Frequent installation errors and their consequences
The most common mistake is an attempt to align the refrigerator only at the front corners, ignoring the general misalignment relative to walls This leads to the fact that visually the refrigerator stands straight, but the doors are skewed. Always use a level, applying it to the top cover in different directions: along and across.
Another mistake is using gaskets made of inappropriate materials. Cardboard folded in several layers or wooden blocks will dry out or become wet over time, and the refrigerator will warp again. Use only metal or plastic adjustment elements provided by the design.
⚠️ Attention: Never leave the refrigerator in the transport position (on its side or strongly tilted) for more than 15-20 minutes before turning it on. The oil needs time to drain into the compressor crankcase.
Do not forget that after installation and first switching on, the refrigerator should operate for several hours without loading food. This will allow the system to reach operating temperature conditions, and you will finally be convinced that the legs are adjusted correctly and that there are no distortions under load.
Is it possible to use the refrigerator without the front legs?
Technically, it is possible if the floor is perfectly flat, but then the necessary slope for closing the doors will not be provided. In addition, without legs, air circulation under the bottom is difficult, which can overheat the compressor.
FAQ: Answers to popular questions
What to do if the floor is very crooked and there is not enough to unscrew the legs?
If the thread reserve of the front screws is not enough to compensate for the height difference, you can use additional pads under one of the front legs. However, it is best to level the floor itself at the installation site or use a sheet of plywood leveled to the level on which the unit will be installed.
Do you need to turn off the refrigerator before making adjustments?
It is advisable, but not necessary. However, if you plan to tilt or move the housing much, it is best to unplug the unit to avoid damaging the compressor or tubing. Let the oil sit for 10-15 minutes after turning off before any manipulations.
Why does the door close on its own, but then open a little?
This may occur due to residual air pressure inside the chambers after slamming. Wait a couple of minutes, the pressure will equalize and the door will snap into place. If the gap remains large, check the cleanliness of the seal and the correct angle of inclination of the case.
Is it possible to remove the base panel to rotate the legs?
Yes, in most models the decorative strip at the bottom is removed. It is usually held in place by latches or magnets. Remove it carefully so as not to break the fastenings, since after adjusting the legs it will need to be returned to its place for estética and protection of the bottom of the case.
How often do you need to check the installation level?
It is enough to check the level immediately after installation and after a month of operation. If the floor is stable and there are no children jumping on it, re-adjustment will not be necessary. On soft surfaces (carpet), an inspection should be carried out once every six months.
