Correct installation of household appliances is the foundation of their long and silent service, and for owners of Belarusian appliances this issue is especially acute. Many users are faced with a situation where, after delivery Atlant refrigerator to the apartment, it begins to hum, vibrate, or do not close the door tightly. Often the reason lies not in a breakdown of the compressor or a defect in the seal, but in a banal misalignment of the case due to an uneven floor.
Modern models, be it a classic two-chamber Atlant MHM 2808 or newer series with the No Frost system, are equipped with adjustable supports. These structural elements allow you to compensate for differences in the height of the floor covering and position the equipment strictly horizontally. Ignoring this installation stage can lead to increased wear of parts and discomfort.
In this article we will analyze in detail the process of setting up supports, explain why this is critically important for compressor, and give practical advice that will help you avoid common mistakes. You will learn to determine the need for adjustment and perform it without calling a specialist.
⚠️ Attention: Before starting any work on the position of the refrigerator, be sure to disconnect it from the power supply. Moving a running unit can damage the cooling system tubes.
Why do you need to adjust the refrigerator supports
The main function of the adjustable legs is to ensure the stability of the case. Floors in apartments, especially in old houses or new buildings with floating screeds, are rarely perfectly level. If Atlant refrigerator stands on a skewed base, the load on its frame is distributed unevenly. This creates additional mechanical stress on compressor and the fastening of the heat exchanger, which in the long run reduces the service life of the unit.
The second, no less important reason is the correct operation of the self-closing door system. The design of the doors of modern refrigerators, including popular models Atlant 4008, is designed for a slight tilt of the body backwards. Gravity helps the door fit tightly to the body after opening. If the equipment is tilted forward or skewed to one side, the door will open spontaneously or, conversely, not fit completely, breaking the tightness.
The third aspect is the noise level. The vibration of a running motor is transmitted to the floor. If the feet are not adjusted, resonance occurs, increasing the hum. Correct adjustment allows you to dampen these vibrations and make the operation of the equipment almost silent.
Diagnostics: how to understand that adjustment is needed
Before taking up the tools, you need to accurately determine the nature of the problem. Visual inspection often does not provide the full picture, so simple inspection methods are recommended. First try rocking the refrigerator from side to side. If it wobbles, it means that one or more supports do not have contact with the floor or, on the contrary, are too raised.
Next, check the operation of the doors. Open the refrigerator door to an angle of about 45 degrees and release. In a working and correctly installed unit, the door should close itself or tend to close under the influence of gravity. If the door remains in place or opens wider, it means that the angle of inclination of the body is broken.
For accurate diagnosis of distortions, it is best to use a building level. Attach it to the top panel of the refrigerator, first along, then across. The air bubble must be located strictly between the risks. If you see a deviation, you need height adjustment support.
The design of adjustable supports for Atlant refrigerators
The design of the equipment's supports Atlant is quite simple and reliable. In the front lower part of the body there are two main supports, which are most often subject to adjustment. They are threaded metal or plastic bushings screwed into the base frame. The rear legs, as a rule, are non-adjustable or have minimal travel for compensation.
In some models, for example, in the series Atlant XM 4425, the front supports can be hidden by a decorative base. In this case, to access the adjustment elements, you will need to remove the plastic panel. Fastening is usually carried out by rotating the leg itself or a special bolt located below.
The material of the supports varies. There are models with plastic threaded bushings that are easy to twist by hand, and options with metal bolts that require the use of a wrench. It is important not to confuse the adjusting support with the transport roller, if it is provided for in the design.
| Type of support | Material | Tool for adjustment | Features |
|---|---|---|---|
| Threaded bushing | Plastic (polyamide) | Manually or with pliers | Often found in budget models |
| Adjusting bolt | Metal (steel) | Open-end wrench (10-12 mm) | High strength, requires effort |
| Support with lock nut | Metal/Plastic | Two keys | You need to loosen the locknut before adjusting |
Step-by-step instructions for adjustment
The adjustment process takes a little time, but requires care. Follow the algorithm to avoid damaging the threads or flooring. Before starting work, prepare the necessary tools: a building level, an open-end wrench (usually 10 or 12 mm) and, possibly, pliers if the legs are plastic and difficult to move.
First tilt the refrigerator back. To do this, it is better to call an assistant, since the unit weighs a lot. Gently lift the front part using the rear legs or wheels. Do not tilt the equipment too much to prevent compressor oil from entering the cooling circuit, although briefly tilting for adjustments is usually safe.
Rotate the front supports. If you need to raise the angle, unscrew the leg (rotate counterclockwise). If you need to lower it, tighten it (clockwise). Make small turns and periodically check the position with a level. Your goal is to achieve a slight tilt back (about 2 degrees) so that the doors close on their own.
☑️ Adjustment algorithm
⚠️ Attention: When rotating metal bolts, apply force evenly. A sharp jerk can break the thread in the frame seat, which will require complex repairs with welding or replacement of the base.
Features of models with the No Frost system
Owners of refrigerators Atlant with the system No Frost should be especially careful to a horizontal position. In such models, air circulation and fan operation depend on the geometry of the internal space. A strong distortion can lead to condensation not flowing into the drainage hole, but accumulating at the bottom of the chamber or, even worse, falling on electrical components.
In addition, No Frost models often use a more powerful compressor and additional fans, which makes the requirements for vibration isolation even higher. The slightest misalignment can turn the quiet operation of equipment into a noticeable hum. Therefore, using a level when installing such models is mandatory and not recommended.
It is also worth considering that some models with No Frost may have heavier doors due to additional elements of the cooling system in the circuit. This increases the requirement for the correct angle of inclination to ensure the self-closing function.
What to do if the threads are soured?
If the adjusting foot does not turn, do not use excessive force. Treat the joint with a penetrating lubricant (such as WD-40) and leave for 10-15 minutes. After this, try to carefully remove the threads using a lever (a wrench with a long handle), but without jerking.
Frequent installation errors and their consequences
One of the most common mistakes is trying to align the refrigerator only with the front panel, ignoring the transverse level check. As a result, the body may stand straight in front, but have a slope to the left or right. This leads to the fact that one of the doors warps and the rubber seal does not fit along the entire length.
Another mistake is completely unscrewing the front supports all the way. This makes the structure unstable. The supports must be securely fixed, and the center of gravity must be shifted inside the perimeter of the base. If you unscrew them too much, the refrigerator may tip over when the top shelf is suddenly opened.
Also, users often forget to secure the position with the lock nut (if provided). Over time, vibration may cause the leg to unscrew or twist spontaneously, and the procedure will have to be repeated again. Always check the reliability of the fixation after completing the adjustment.
Maintenance of the supports during operation
Over time, under the weight of the equipment and the influence of vibration, the position of the legs may change. It is recommended to carry out a preventive examination once a year. Check for any gaps between the leg and the floor and tighten them if necessary. This is especially true for houses with wooden floors that can “walk.”
If the floor in the room is slippery (tiles, laminate), you can put special rubber pads on the legs of the refrigerator. They will increase the coefficient of friction and prevent accidental movement of equipment when opening doors. However, make sure that the pads do not interfere with stability.
In case of replacing the floor covering or moving, the adjustment procedure must be carried out again. Even if the floor appears visually smooth, the microrelief of the new coating may require correction of the height of the supports to ensure ideal operation of your Atlanta.
Is it possible to level the refrigerator by placing cardboard or wood under the legs?
It is strictly not recommended to use soft or deformable materials (caron, thin wood, plastic) for alignment. Under the weight of the refrigerator, such gaskets will eventually become wrinkled, which will lead to new distortion and loss of stability. Use only standard adjustable supports.
Why does the Atlant refrigerator stand level, but the door does not close?
If the level shows normal, but the door does not close, the problem may not be in the legs, but in overhanging the door, dirty seal or loose hinges. Also check whether the shelves on the door are loaded with too heavy objects, which shifts the center of gravity.
Do you need to adjust the rear legs?
In most models of Atlant refrigerators, the rear supports are non-adjustable and serve only for support. Adjustment of height and angle of inclination is carried out exclusively by the front screw supports. The rear legs can only be slightly raised if the design allows, but the main load for leveling lies on the front ones.
What if one of the front legs breaks?
If the threaded bushing has burst, you cannot operate the refrigerator in this form - it is dangerous. It is necessary to order an original spare part from a service center or select an analogue in terms of thread and diameter. You can temporarily use a wooden block of suitable height, but this solution is only for a couple of days before the technician arrives.
