The life expectancy of a typical appliance depends to a great extent on the use it receives.
Moreover, appliances are often replaced long before they are worn out because changes in styling,
technology and consumer preferences make newer products more desirable. Of the major appliances
in a home, gas ranges have the longest life expectancy: 15 years. Dryers and refrigerators last about
13 years. Some of the appliances with the shortest lifespan are: compactors (6 years), dishwashers
(9 years) and microwave ovens (9 years).
