I have a Candy frost free f/freezer about 1year old. It makes excessive noise, in the quiet of the night sounding like a small aircraft taking off. It is only occasionally, and briefly, silent. Likely to resemble a chainsaw on the simple act of opening the door. Highly necessary, given the purpose of the confounded machine. I am the second owner, the first having given up with the noise and banished it from the house. Any ideas??
