What is the average life expectancy of a micowave oven?

Sunday, March 1, 2020

You can expect a microwave oven to last about 7 to 9 years, with an average of 8 years. Heavy use, such as by college students or a large family to heat up meals and snacks, will shorten the life expectancy. Here’s a graph comparing microwave life expectancy to other home appliances.
    Go to our blog post What is the average lifespan of the parts of a house? for rating of other house components. To understand the basis, potential use, and limitations of lifespan ratings, see our blog post How accurate are the average life expectancy ratings of home components? Are they actually useful?  

    To learn about the problems we often find with microwaves at home inspections, see our blog post What are the most common defects with over-the-range microwaves?

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMade, and our own professional experience. Because of the numerous variables that can affect a lifespan, they should be used as rough guidelines only, and not relied upon as a warranty or guarantee of future performance.
