3.10 Noises or bangs:
This concept is very objective.
Depending on its location, the time of day and a person's perception, the concept of noise varies greatly. As means of an example, during the day a mosquito is completely inaudible. However, once it is night and the noise of everyday life subsides, nothing is more unbearable, however, if the dB (A) levels are measured it cannot be perceived.
The refrigerating gas circulates through coils. The gurgling noise, small creaks and light bangs are normal.
Check to ensure a bridge of ice has not formed between the evaporator and the wall protection, which can generate a considerable amount of noise when defrosting (remove the protection).
If the bangs occur during the start-up or shut-down or only when the compressor is deactivated; replace the compressor (only to be completed by specialist technicians)
The contraction and expansion of the internal walls can generate creaking noises of varying intensity.
