Are you wondering how long do microwaves last?

You’ve come to the right place! Understanding the lifespan of your microwave can help you plan for its replacement and budget accordingly.

The lifespan of a microwave can vary depending on the frequency of maintenance, type, brand, and extent of use. A well-maintained microwave can last up to 10 years.

I had to look up the word “limber” since it’s been absent from my life for so long.

I remember when the wife and I were looking for our first house twenty five years ago. The first house we looked at had this awsome original kitchen from the 1950’s. It was so cool with all the original appliances that still worked because they were built to last. Wife said we couldn’t buy the house because redoing the kitchen would be too expensive. I kept my mouth shut and moved on.

Same here. Used every day and bought it in 20 years ago. They don’t even make a better model today.

I had one go bad. It had nothing to do with the microwave oven itself.

It was an over-the-stove oven, and the plastic moulding began to crack and fall off, eventually causing the glass window to fall out.

I was told this was due to the heat from stove deteriorating the plastic on the door.
