Vibrating high pitched noise occurs like every 20-30mins and last like 5-10 seconds. I can hear the noise from my bedroom at night time (approx. 4meters away) and found it very disturbing. I don't think its normal to have noise like that and also so frequent. I reported the issues to the customer centre and I was requested to record the noise which is impossible. I don't like the fridge and disappointed with the good guys' customer service.
