People attach great importance to household appliances. As large household appliances, refrigerators are naturally one of the items that people pay attention to, because most of the prices of refrigerators are more than 1,000 yuan, accounting for a large proportion of living expenses, and people’s life has been inseparable from refrigerators, so when choosing refrigerators, we will carefully choose, as far as possible to choose refrigerators that are in line with family use. Even if it is a high-quality refrigerator, there will be some problems, such as the refrigerator sound is too large, will make a buzzing sound, we must not ignore. Here’s why your fridge is loud and what to do about it.
What about the loud refrigerator? The reason for the loud buzzing
1. The refrigerator should be placed on a flat and firm place, so that the four corners of the bottom of the refrigerator are on a plane to achieve balance. General manufacturers own refrigerator bottom four-foot adjustment balance knob, can be adjusted to the minimum noise fixed. If there is no balancing knob device, rubber cushion can be added at the foot of the refrigerator to achieve balance and minimize noise.
2. Check whether the reinforced connection between the external pipe and the container is loose to prevent resonance when the compressor works. Therefore, the external pipeline must be fixed, bolt to add spring washer, to prevent loose.
3. If the noise is obviously reduced when the compressor is pressed tightly by the hand, and the noise increases when the hand is lifted, it is generally caused by the uneven stress of the fixed vibration damping cushion on the compressor base, loose bolts, and unstable compressor bottom plate. It is necessary to adjust and tighten the connecting bolts and replace the washers that lose elasticity.
4. In the refrigerator and cold room, the manufacturer is equipped with ice box, layered network, drawer and other accessories for the user, which should be firmly installed according to a certain position and slot edge. Do not put debris on the top of the refrigerator to prevent resonance noise.
5. When the hand presses the top of the compressor, the noise is still not reduced. Usually, the gap between the piston and the cylinder in the compressor is too large and causes the noise. In addition, when the refrigerator does not open the door, about 3 meters away from the refrigerator, obviously hear the sound of boiling pot or interval “wheeze”, is the failure of refrigeration pipeline, should be repaired by professional personnel.
6 refrigerator in the process of use, such as large noise, preferable waste bicycle tire, cut into a diameter of 30 mm round shape, cut out a diameter of about 5 mm round hole in the middle, and then cut from the outside to the center, in order to put the rubber on the pipe. When the refrigerator compressor is running, touch the pipe by hand. If the pipe has the feeling of shaking, it can be set with several of these rubber blocks. A refrigerator needs to set 10 ~ 20, and the noise will drop immediately. This is because the rubber block suppresses the “resonance” caused by the vibration of the tube.
7. The height of the refrigerator pad is 3 ~ 6 cm and the balance of the four corners is adjusted so that the air convection space at the bottom of the box body is increased. In this way, the compressor noise and other lower noise from the bottom of the box, reducing the noise from both sides and the upper part of the refrigerator.
8. The back of the refrigerator and the wall into a certain Angle, the back and the wall into l ~ 3 degrees of Angle, the refrigerator side of the opening is large, one side of the opening is small, showing the shape of a horn. The big side released more noise, should face the object, the small side noise out less, should face the people’s activity area.
9. Glue fiberglass cotton and other sound-absorbing materials to the cardboard, and then nail the cardboard to the wall behind the refrigerator (compressor side). The cardboard is 10 ~ 20 cm larger than the back of the refrigerator around the side.
The loud noise of the refrigerator must be the refrigerator has a problem, it may cause danger to our life, so we must check in time, if we can not solve the problem, we should call the after-sales professionals to check and repair the refrigerator as soon as possible. In addition, the refrigerator has serious radiation problems, but also produce freon, which is very polluting to the environment, so we try to choose the refrigerator of energy saving and environmental protection, but also pay attention to its after-sales service and quality, a good refrigerator can be used for ten years.
