Sur - we took delivery of our BC 3650 the second week of June and that was the first thing that we noticed - loud refrig motor. It's strange cuz of the 3 HL coaches that we have had, this is the first one thats noisy. Tonight I even noticed the side frames around the doors being warm which the other refrigs in the past haven't been. I was going to give it another month and then think will contact someone or the manufacture in reference to this.
