Question

I bought a 15 Cu. Foot Hotpoint refrigerator in June, 2007 and everytime it runs, it makes noises like a dog barking and a moaning noise. I was told by a co. rep. that this is natural in present day refrigs. I do not agree as I have in my 75 years had numerous refrigs and none of them have made this noise. I want to have this repaired before the warranty expires. Can you tell me what is wrong with it and the nearest Service Center close to Harrisburg, Pa.?
