My refrigerator is not cold, and furthermore always beeping. The beeping would stop if I touched any button of the temperature control. This happened since the mechanic fixed the fridge last month. The dealer in HK refused to re-fix it as it over one month. In fact this happened since the last fixing and I did not report only because I was not in HK and the maid did not know how to follow-up. Grateful if you could help me. I think it might be I don't know how to tune it. Thank You.
