I purchased a Kenmore refrigerator yesterday and knew about the model prior to purchase. It makes the eighth one folks in our family have. We have two of that model in our home and this one is for a rental unit. They sales clerk would not give up about being super pushy on selling an extended warranty. She nearly demanded a purchase of one from every customer she approached. At check out, she ask me a half dozen times to purchase one. Then she asked how I wanted to pay for the extended warranty after continually telling her no. She indicated how foolish it is to not purchase one, how low-quality appliances are made, how I could get more money if it broke since it was a scratch/dent, how much it cost to repair appliances. Her diatribe never ceased. I am guessing they get a commission on the sale of warranties.
Sears wanted $189 for a three year warranty, or two additional years for a scratch and dent $519 refrigerator. I checked at the Home Depot and they would charge $65 for an extended warranty at the same price point. American Express doubles the warranty on appliances for free, so in reality the warranty would only offer one extra year. About this time every year some news agency does a story on how worthless extended warranties are to consumers but in November & December people will spend 1.2 Billion dollars on extended warranties.
As far as appliances go, you typically see a "bathtub" curve on break downs. You either typically see them immediately upon purchase or just before they bite the dust for good. Not so many problems in the middle. Research has shown this for quite some time.
