  • Page 42 Hertz. Reasons for compressor noise are: (1) There are two pieces thin elastic steel slice inside the compressor (gas in valve and gas out valve), when the freezer starts, each steel slice will open and close about 47 times per second, this will cause vibration sound.
  • Page 43 This sound is different, for the evaporator used and assembly technologies during producing are different. If there is not this sound at freezer operation, and evaporator cannot make refrigeration, condenser is not hot, this means there is restriction or there is a refrigerant leak.
  • Page 44 This sound may occur at the following situations: (1) Newly bought freezer, the internal stress of materials has not been eliminated. With time going on, the stress of materials will disappear and it is less possible to make this sound.
  • Page 45 Answer: After half a year or one year’s use, clearance will increase because of wear of inner components, and compressor’s noise will increase accordingly. Then it will get stable till the whole life of freezer. 12.6.7 Why freezer’s noise increases after stop use for...

  • Page 48 Maintenance Service and Trouble Shooting The standard 42dB of the ministry of light industry is the noise pressure level measured 1m away from freezer door. This value plus 10 is the approximate value of sound power level. The restriction to noise in national standard is more strict and scientific. At present, freezer noise is required to take sound power level stipulated in national standard.
  • Page 49 Model:FHV5SGWW/FHV7SGWW MAINTENANCE SERVICE AND TROUBLE SHOOTING Maintenance Service and Trouble Shooting (2) When freezer stops, because of inertial rotation, there will be vibration sound from compressor. (3) When freezer stops, the compressor decelerates, high pressure and low pressure at gas exhausting tube and returning tube will get balance, thus causes sound of compressor.
