Our brand new (installed 11/13/2015) KitchenAid refrigerator runs noisy/loud (Model KRFF507ESS). I called KitchenAid Customer Warranty within 72 hours of purchase and Customer Service representative Eric sent me the below link, telling me this is usual and customary noise for a refrigerator. I have NEVER heard a refrigerator this noisy on any showroom nor in anyone's home. They are refusing to send someone out to assist with this noise issue, stating it is "normal". Has anyone run into this problem and, if so, what did you do? This is interfering with the peaceful enjoyment of our home.
