Microwaves usually have a 10 year lifespan give or take a few years and it also depends on use. Over the range is still a microwave and there is nothing special about it other than it being over the range. Older microwaves need to be discarded because of radiation concerns. If the microwave loses power and/or doesn't work anymore the best thing to do is to find a replacement. By the time you put all of the money and effort into getting the old one fixed you will probably save money by finding a new used one or purchasing a brand new one.

Scientists are still researching the exact nature of the aging process, but in general, we can observe that the human body is a very complex structure which accumulates a variety of errors and failures over time. It could also be argued that the process of evolution requires older generations to die and be replaced by younger generations, and therefore we have evolved specifically to have a limited lifespan.
