How Long Should a Microwave Last?
A microwave is a lifesaver in the kitchen. It warms the rice while you continue cooking on the hob. It reheats food when your guests are a little late for dinner. It even keeps your kids occupied with their favorite buttery popcorn and hot chocolate with marshmallows on top. It truly is a godsend.
But unfortunately, these rectangular sous-chefs don’t last a lifetime. In fact, the average lifespan of a microwave is just 8 years. But in many busy households, a microwave doesn’t usually see past its 5th birthday.
All this may have you wondering how long your microwave will last. To find out, confirm what kind of microwave user you and your family are. You will then be able to see how long you can expect your electrical right-hand-man to stick with you in the kitchen.
Heavy Use
How much do you and your family use your microwave? Do you:
- Have a large family (more than 4)?
- Use the microwave constantly throughout the day to heat snacks and defrost food?
- Rarely carry out maintenance on the microwave?
Is your microwave constantly being used throughout the day? Then it will only last about 4-5 years. This is especially true if you do not keep up with the maintenance of the microwave.
But what does good microwave maintenance involve? Take a look at the information below to find out.
Good maintenance for your microwave means:
- Immediately cleaning up any spills.
- Periodically degreasing the grease filter.
- Wiping moisture off of the microwave while you cook in the kitchen.
- Calling an electrician when you have a problem with the microwave.
Even if your microwave is in constant use, you can extend its lifespan by at least a year with good maintenance.
Normal Use
How often you use your microwave will affect its lifespan. Do you:
- Have an average-size family (about 4 people)?
- Use the microwave a couple of times a day to heat snacks and defrost food?
- Keep up with the maintenance of the microwave?
If your microwave usage falls into the “normal” category then you can expect yours to last about 7 years. It could even last up to 8 years if you follow a good microwave maintenance schedule.
Infrequent Use
Do you seldom use your microwave? Do you:
- Live on your own or with one other person?
- Use the microwave just once or twice a day?
- Keep up with the maintenance of the microwave?
Does your microwave usage fall into the “infrequent” use category? If so, then you can expect yours to last up to 10 years. This is especially true if you keep up with a good maintenance schedule.

What Are the Signs a Microwave Is Going Bad?
Do you suspect that your microwave is at death’s door? A microwave is a super handy appliance to have in the kitchen. So, you’ll no doubt want to replace it before it kicks the bucket on its own. But, which signs should you look out for that will let you know that it has come to the end of its life? You can take a look at some of them below.
1. Worn-Out Buttons
Are the buttons on your microwave a little worn out? Do you have to shove your finger onto the keypad with all your might for it to react? Or have some of the buttons and programs stopped working completely? If so, then it’s likely that your keypad is just a few jabs of a finger away from failing to respond altogether.
2. Slow Heating
Who doesn’t love juicy slow-cooked pork? That’s right, every household needs a slow cooker. But what you don’t need is for that slow cooker to be your microwave.
Your microwave should heat things quickly. It should be able to turn a mug of cold water piping hot in just two minutes. Is your microwave taking longer than usual to heat meals? Then the likelihood is that it’s about to give up the ghost.
3. Loud Operating Noises
Your microwave should operate while making no more than a low hum in the background. It shouldn’t be any louder than 55-59 dBA. (That’s just quieter than a normal conversation but louder than your bathroom exhaust fan.) Does your microwave:
- Rattle?
- Clang?
- Buzz?
If so, then, you’ve guessed it, it’s time to look for a replacement.
4. Over 10 Years Old
Is your microwave over 10 years old? I know that everyone loves a classic. And they say if it’s not broke don’t fix it. But, even if your microwave is still in good condition you should start looking for a replacement. Why’s that? Take a look at a few reasons below:
- New microwaves are more energy efficient. A new one could save you some money on your electric bill.
- New microwaves have the most up-to-date smart features.
- It is more expensive in the long run to repair a microwave than it is to buy a new one. Save yourself the hassle of trying to find discontinued replacement parts on the internet. Treat yourself to a new model!

The average lifespan of a microwave is just 8 years. But we all want our microwaves to last as long as physically possible. This could be a little tricky if your microwave is in constant use throughout the day. I’m sure this article has shown you some methods you can use to extend the lifespan of your microwave.
