My new refrigerator started making a loud noise (intermittent) shortly after we got it. Sears service came out and could not find problem. Tech said wait until it gets worse and call again. It has gotten worse, I called to check on it and I am told it is out of warranty about 4 months. Now sears has told me I will have to pay to fix a problem that should be under warranty. Does anyone else have a similar problem?
