People attach great importance to household appliances, as a large household appliances, refrigerator is naturally one of the items that people are concerned about, because the price of the refrigerator most of them are more than a thousand dollars, accounting for the proportion of the cost of living is large, and people’s lives have been inseparable from the refrigerator, so in the choice of refrigerator, we will be carefully selected, as far as possible to choose the refrigerator in line with the family use. Even if it is a high-quality refrigerator, there will be some problems, such as the sound of the refrigerator is too loud, will make a humming sound, we must not ignore. The following is to explain the reasons for the refrigerator sound and solutions.
1. refrigerator should be placed in the ground flat, firm place, so that the bottom corners of the refrigerator in a plane and achieve balance. General manufacturers come with the bottom of the refrigerator four feet to adjust the balance of the knob, can be adjusted to the noise minimum hour fixed. Such as no adjustment balance knob device, can be added under the refrigerator feet pad rubber pad, etc., so that it reaches balance, noise minimum.
2. check and adjust the outer pipeline and the box between the connection reinforcement part is loose, so as to avoid the compressor work resonance. Therefore, the external pipeline must be fixed and the bolts should be added with spring washers to prevent loosening.
3. If the compressor by hand, the noise is significantly reduced, the hand will be raised noise and increase, generally is the compressor base fixed damping rubber pad uneven force or bolt loose, the compressor base plate is not solid, should be adjusted, tighten the connection part of the bolt and replace the loss of elasticity of the gasket.
4. refrigerator freezing and freezing room, the manufacturer for the user with ice box, layered network, drawers and other accessories, should be installed securely according to certain location and slot edge. Do not put debris on the top of the refrigerator, to prevent resonance noise.
5. When the hand press the top of the compressor noise still does not reduce, usually is the compressor internal piston and cylinder clearance is too large and cause noise, then should replace the compressor. In addition, the refrigerator in not open the door, about 3 meters from the refrigerator, obviously hear the sound of boiling or interval “giggling sound”, is the refrigeration pipeline failure, should ask professionals to repair.
6. refrigerator in the process of use, such as noise, can take the waste bicycle outer tire, cut into a diameter of 30 mm round shape, the middle cut out of the diameter of about 5 mm round hole, and then from the outside to the center of the cut, in order to put the rubber paste to the tube. Refrigerator compressor operation, touch the tube, where there is a shaking feeling of the tube, can be set on a few of this rubber block, a refrigerator need to set 10 ~ 20, the noise will immediately come down. This is because the rubber block inhibits the tube vibration generated by the “resonance”.
7. will refrigerator pad high 3 ~ 6 cm and adjust the four corners of the balance, so that the bottom of the box air convection space increases. In this way, the compressor noise and the lower other noise from the bottom of the box, reduce the noise from both sides of the refrigerator and the upper out.
8. the back of the refrigerator and the wall into a certain angle of inclination, back and the wall into l ~ 3 degrees after the angle of inclination, one side of the refrigerator opening large, one side of the opening small, showing a trumpet shape. Large side of the noise put out more, should face the object, small side of the noise out less, should face the human activity area.
9. the glass fiber wool and other sound-absorbing materials glued to the cardboard, and then nail the cardboard in the refrigerator (compressor side) behind the wall, cardboard than the refrigerator back side around the big 10 ~ 20 cm can be.
Refrigerator loud sound must be a problem with the refrigerator, it may cause danger to our life, so must be timely view, if they can not solve the problem, we must call as soon as possible to let the after-sales professionals to check, repair the refrigerator. In addition, the refrigerator has a serious radiation problem, will also produce freon, which is very big pollution of the environment, so we try to choose the refrigerator in the choice of energy-saving environmental protection refrigerator, but also pay attention to its after-sales service and quality, a good refrigerator can basically use ten years.
