LIke anything else, a warranty is nice to have when something goes wrong. Most refrigerators last as long as nine years, according to a report by the Interational Assocation of Certified Home Inspectors. That's a lot longer than most warranties, and even the most robust warranties are typically only 10 years. The fact is, your warranty is likely only going to save you in the event that you got a lemon with serious malfunctions that would likely emerge soon after you plug it in.
