The condenser vibrates

(1) Cause analysis: In the use of the refrigerator, sometimes you can hear the shaking sound or crackling sound issued by the condenser, this sound mostly appears in the louver condenser, so the condenser is the cooling tube squeezed on the louver plate heat sink, forming a whole, but in the production process, or due to other reasons, often cause the combination between the cooling tube and the heat sink to become poor. Therefore, in the operation of the compressor, due to the difference in temperature difference between the inside and outside of the condenser tube, as well as the difference in the thermal expansion coefficient of the cooling tube and the heat sink, the two produce a loosening phenomenon, which makes a crackling sound, although this sound does not affect the use of the refrigerator temporarily, but the long-term sound is annoying, and the cooling tube will be damaged. Causing refrigerant leakage.

(2) Elimination method: Stop the operation of the compressor, and then drop 502 glue in the loose place of the cooling pipe and heat sink, dry solid after a day, and then start the compressor to operate, there will be no noise.
