How Long Do Microwaves Last
The Average Lifespan Of Microwaves
When it comes to appliances, microwaves tend to have a pretty good lifespan. But, like all things, they eventually reach the end of their life and need to be replaced.
So, how long do microwaves last typically?
Most microwaves only last around 9 to 10 years before they need to be replaced. That’s not to say that all microwaves only last 10 years, but it’s definitely the average.
Of course, this can vary depending on the brand, model, and how often it’s used.
For example, a high-end microwave that’s used infrequently may last up to 15 years, while a lower-end model that’s used daily may only last 5 years.
So, while the average lifespan of a microwave is 9 years, yours could last anywhere from 5-10 years or more. If you take good care of it and don’t use it excessively, you could even get up to 15 years out of it.
There are a few things that can shorten a microwave’s lifespan, such as overloading it or using it to heat up greasy or oily food.
If you take good care of your microwave and use it as intended, it should last you a good long while.
10 years is the average, but there are always outliers. Some microwaves last much longer, while others only last a few years. It all depends on how you use and care for your microwave.
So, if your microwave is getting up there in age, don’t be too worried. It’s probably just time for an upgrade. And, who knows, the new model might even have some features that your old one didn’t have!

Factors Affect The Lifespan Of Microwaves
The lifespan of a microwave can be affected by a number of factors, from the quality of the unit to how often it’s used. But with proper care, most microwaves can last for years, even decades.
There are several factors that can affect the lifespan of a microwave, such as:
The Quality of the Unit
When it comes to appliances, you usually get what you pay for. That’s why it’s important to invest in a high-quality microwave.
Cheap, poorly made units are more likely to break down and need to be replaced sooner. Spend a little extra to get a well-made, durable microwave and it will pay off in the long run.
How Often It’s Used
How often you use your microwave also plays a role in how long it lasts
If you use your microwave several times a day, it will naturally have a shorter lifespan than one that’s only used occasionally.
That’s because more frequent use puts more wear and tear on the appliance. If you want your microwave to last, try to use it only when necessary.
The Type of Use
Not all uses for a microwave are created equal. Heating up a cup of coffee or a frozen meal is much less demanding on the appliance than, say, cooking a Thanksgiving turkey.
If you’re planning to use your microwave for heavy-duty tasks, look for a unit that’s designed to handle that type of use.
Care and Maintenance
How well you take care of your microwave also affects its lifespan. If you clean it regularly and don’t overload it, it’s going to last longer than if you let it get dirty and never clean it.
Even the best-made, most expensive microwave won’t last long if it’s not properly cared for. Be sure to clean the unit regularly, both inside and out.
And if something does break, don’t try to fix it yourself. Call a professional to handle any repairs.
So, if you want your microwave to last as long as possible, buy a high-end model from a reputable brand and take good care of it.
And, if you use it multiple times per day, consider getting two so you can rotate them and give each one a break.
While the average lifespan of a microwave is 10 years, there are several factors that can affect this.
The brand, model, usage, and care all play a role in how long do microwaves lasts. So, if you want yours to last as long as possible, keep these factors in mind.
You’re Shortening the Life of Your Microwave By…
While the average lifespan of a microwave is 9 to 10 years, there are several things you can do that will shorten its life.
If you’re doing any of the following, you’re likely reducing the amount of time your microwave will last.
1. Overloading the microwave
One of the quickest ways to shorten the lifespan of your microwave is by overloading it.
Every time you try to cook too much food at once, you’re putting stress on the appliance and wearing it down. This can shorten the life of your microwave and even cause it to catch fire.
To avoid this, make sure you only cook small amounts at a time. If you’re cooking for a large group, cook in batches instead of all at once.
2. Using the wrong type of cookware
Another common mistake people make is using the wrong type of cookware in their microwaves. Some materials, like aluminum foil, can cause sparks and even fires.
To avoid this, only use cookware that is specifically designed for use in microwaves. If you’re not sure if something is safe, check the manufacturer’s instructions or do a quick internet search.
3. Not cleaning it regularly
If you don’t clean your microwave regularly, you’re shortening its lifespan. Food particles and grease can build up on the interior of the unit and cause damage.
Even if you only use it for heating up food, food particles can build up and cause problems.
To avoid this, make sure to clean your microwave at least once a week. You can use a microwave-safe cleaning solution or just a damp cloth.
So, be sure to clean your microwave regularly, both inside and out.
4. Using it for everything
While microwaves are great for heating up food, they’re not designed to be used for everything. For example, you should never put metal in a microwave, as it can cause sparks and even fires.
To avoid this, only use your microwave for its intended purpose – heating up food. If you need to heat up something in a hurry, there are other methods that are safer, such as using a stovetop or oven.
5. Slamming the door
Slamming the door of your microwave is one of the quickest ways to shorten its lifespan.
Every time you do it, you’re putting stress on the hinges and wearing them down. So, if you want your microwave to last, be sure to close the door gently.
6. Running it while it’s empty
Running your microwave while it’s empty is a bad idea because it can cause damage to the appliance. So, if you want to prolong the life of your microwave, only run it when there’s food in it.
7. Not giving it space
Another common mistake people make is not giving their microwave enough space. If you don’t have enough clearance around it, the heat can’t circulate properly and it can cause damage to the unit.
To avoid this, make sure there’s at least 3 inches of space on all sides of your microwave. And, if possible, keep it away from heat sources, such as stoves and ovens.
8. Forgetting to use the ventilation fan
If your microwave has a ventilation fan, be sure to use it when cooking. The fan helps to circulate the air and keep the appliance from overloading.
To use the fan, simply turn it on before you start cooking. And, if your microwave doesn’t have a fan, be sure to open the door periodically to let the heat escape.
9. Leaving it on 24/7
If you leave your microwave on all the time, you’re shortening its lifespan.
Even when you’re not using it, the appliance is working hard to keep food warm. So, if you want your microwave to last, be sure to turn it off when you’re not using it.
10. Not following the manufacturer’s instructions
If you don’t follow the manufacturer’s instructions, you could be shortening the life of your microwave. Every model is different, so it’s important to read the manual before using it.
If you don’t follow the instructions, you could damage your microwave or even cause it to catch fire. So, take the time to read the instructions before using your microwave.
By following these tips, you can prolong the life of your microwave and keep it working properly for years to come.
Tips To Lengthen a Microwave’s Lifespan
Here are some tips to help you get the most out of your microwave and keep it running for as long as possible.
1️⃣ Use it regularly
One of the best ways to keep your microwave running efficiently is to use it regularly.
This helps to prevent the build-up of dirt and grime, which can cause the microwave to overheat and eventually break down.
If you only use your microwave occasionally, it’s a good idea to give it a good clean every few months to keep it in top condition.
2️⃣ Avoid overheating
Microwaves can overheat if they’re used too often or for too long at a time. This can damage the internal components and shorten the lifespan of the appliance.
If you notice that your microwave is starting to overheat, it’s best to stop using it and allow it to cool down before using it again.
3️⃣ Don’t use it for everything
Microwaves are great for reheating food and drinks, but they’re not designed for cooking from scratch.
Using your microwave to cook food can cause it to overheat and break down prematurely.
If you want to cook food in your microwave, it’s best to invest in a microwave-safe cooking bag or container.
4️⃣ Keep it clean
One of the best ways to keep your microwave running efficiently is to keep it clean. Dirt and grime can build up on the interior surfaces, causing the microwave to overheat and eventually break down.
It’s important to clean your microwave regularly, both inside and out. Use a damp cloth or sponge to wipe down the interior surfaces, and use a mild detergent to clean the exterior.
5️⃣ Be careful with what you put in it
Microwaves can be damaged by certain materials, so it’s important to be careful with what you put in them.
Avoid using metal containers, as they can cause sparks that can damage the microwave. If you’re reheating food in a plastic container, make sure that it’s microwave-safe.
6️⃣ Don’t overdo it
Using your microwave too much can shorten its lifespan. If you find that you’re using it multiple times a day, it’s best to invest in a second appliance.
This will help to prolong the lifespan of your microwave and keep it running efficiently for many years to come.
By following these tips, you can help to prolong the life of your microwave. Just remember to use it safely and carefully, and you’ll be able to enjoy its convenience for years to come.
