Microwave Oven Longevity

[Monk]

My mother died in 1991. Her first microwave, which we had and used for years before her passing, is a very large, brown Sharp Carousel with convection oven and still works, almost twenty years later. It's not in regular use now; I just tested it recently and it did work--pretty amazing.

We had one like that when I was little, lasted a good fifteen years. Come to think of it the poor thing never broke, it just stopped cooking things all the way through. It probably had another three years of substandard life in it. They don't make 'em like they used to.

The one currently in use here is an Emerson (this is the closest to I can find. Not sure if it's the exact model) and it's lasted for a easy four years.

Other posters are right, microwaves should definitely last you longer than they are Kukri. Are your factory warranties still good by chance?
