Most microwaves need to be replaced after only nine to ten years of use. 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. You might even get up to 15 years out of it if you take good care of it and don’t use it excessively.

Overloading a microwave or heating greasy or oily food are two examples of how to reduce its lifespan.

Your microwave should last you a very long time if you take good care of it and use it properly.

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 handle and maintain your microwave.

So, if your microwave is getting on in years, you shouldn’t worry too much. Probably all that’s needed is an upgrade. And who knows, your old model may not have had some features that the new one does!

Factors Affect the Lifespan of Microwaves

A microwave’s lifespan can be impacted by a variety of elements, including the unit’s quality and usage frequency. However, most microwaves can last decades with the right maintenance.

There are several factors that can affect the lifespan of a microwave, such as:

The Quality of the Unit

You typically get what you pay for when it comes to appliances. It is crucial to spend money on a high-quality microwave because of this.

Cheap, poorly made units are more likely to break down and need to be replaced sooner. A well-built, durable microwave will be worth the extra money in the long run.

How Often It’s Used

How often you use your microwave also plays a role in how long it lasts

Naturally, a microwave that is used frequently will last less time than one that is only occasionally used.

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

Every microwave has its own set of applications. Compared to, say, cooking a Thanksgiving turkey, heating up a cup of coffee or a frozen meal is significantly less taxing on the appliance.

Look for a microwave that is made to handle heavy-duty use if you intend to use it for that purpose.

Care and Maintenance

The lifespan of your microwave also depends on how well you take care of it. It will last longer if you keep it clean and don’t overuse it than if you let it accumulate dirt and never clean it.

If it isn’t taken care of properly, even the most expensive, best-built microwave won’t last very long. Make sure to regularly clean the appliance inside and out.

Additionally, avoid attempting to fix anything that breaks on your own. To handle any repairs, contact a professional.

So, if you want your microwave to last as long as possible, invest in a high-end model from a trusted manufacturer and treat it well.

Additionally, if you use it frequently, think about purchasing two so you can alternate them and give each one a break.

A microwave has a 10-year lifespan on average, but there are a number of factors that can change 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.

6 Signs It’s Time to Replace Your Microwave

Your microwave wasn’t made to last forever, like all kitchen appliances. It will eventually require replacement. Here are the telltale signs that it’s time to start looking for a new microwave, the only question is when.

1. Smoke, Sparks, and Burning Smells.

These are indicators of a critical and pressing issue. Stop what you’re doing right away, and unplug and turn off the microwave. If you spot smoke, sparks, or the burning smell, there is no turning back. It’s time to get a new microwave because yours is breaking down.

2. Food Isn’t Cooking Properly.

The fact that microwaves significantly shorten cooking times is one of their appeals. If your microwave is heating food much slower than normal, or not at all, something is off.

Test your microwave if you believe its power is beginning to fade. Using high power for two minutes, boil one cup of water. Consider getting a new microwave if it’s not scorching hot.

3. It Makes Horrible Sounds as It Cooks.

Your microwave should operate quietly while cooking, producing no more than a soft hum. The opposite is true if it starts to make loud noises like grinding, buzzing, or rattling. Start by inspecting the fan and turntable. It’s simple to correct a food leftover or alignment issue. If those areas are examined and found to be in good condition, there may be a larger issue that can best be solved by purchasing a new microwave.

4. the Door Doesn’t Seal Properly.

The microwave door must be completely sealed when closed. This crucial safety measure is intended to contain radiation. This alone is reason enough to get a new microwave if it appears cracked, severely worn, or broken.

5. The Keypad Doesn’t Function

Microwave cooking is impossible without the keypad. When you enter the cook time, power setting, or start button, it should respond. If not, things might be getting worse. The keypad might only require a thorough cleaning. But if that doesn’t work, it might be time for a replacement.

6. It’s over 10 Years Old.

The majority of microwaves have a 10-year lifespan. However, even if yours is older than ten years and seems to be in good condition, it might be time to upgrade because technology advances and most appliances become much more energy efficient.

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.

Use It Regularly

Utilizing your microwave frequently is one of the best ways to maintain its effectiveness.

This assists in avoiding the accumulation of dirt and grime, which may lead to the microwave overheating and eventually breaking 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.

Avoid Overheating

Microwaves can overheat if they’re used too often or for too long at a time. In addition to shortening the appliance’s lifespan, this could harm its internal parts.

It’s best to stop using your microwave and give it some time to cool down if you see that it’s starting to overheat.

Although they are excellent for reheating food and beverages, microwaves are not made for cooking from scratch.

Using your microwave to cook food can cause it to overheat and break down prematurely.

It is best to spend money on a microwave-safe cooking bag or container if you intend to cook food in your microwave.

Keep It Clean

One of the best ways to keep your microwave running efficiently is to keep it clean. The interior surfaces of a microwave can collect dirt and grime, which can lead to an increase in temperature and eventual breakdown of the appliance.

Regularly cleaning both the inside and outside of your microwave is crucial. Clean the interior surfaces with a damp cloth or sponge, and wash the exterior surfaces with a mild detergent.

Be Careful With What You Put in It

Being cautious with what you put in microwaves is important because some materials can harm 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.

Don’t Overdo It

Its lifespan may be shortened if your microwave is used excessively. It’s best to buy a second appliance if you discover that you’re using it several times per day.

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.

How to Dispose of An Old Microwave Safely

When your microwave begins to malfunction, it might be time to start planning how to safely dispose of it.

If you’re not sure what to do with your old appliance, here are a few tips on how to get rid of a microwave oven:

Ask the recycling facility in your area. Microwaves can be recycled at a lot of places. This is frequently the simplest and greenest method of getting rid of an old microwave.
Donate your microwave to a nearby charity or secondhand shop. Your appliance might be useful to someone else if it’s still in good working order.
Online or at a garage sale, offer your microwave for sale. If your appliance is still in good shape, this is an alternative.
Call the waste removal company in your area. You might be able to have your microwave picked up as part of your regular trash service in some circumstances.
Take your microwave to a landfill or dump. Since microwaves can occupy valuable landfill space, this should only be used as a last resort.

Be sure to abide by all local laws and ordinances when getting rid of a microwave. This will aid in ensuring that your outdated appliance is discarded legally and safely.

It’s critical to properly dispose of your old microwave if you’ve decided to replace it. If microwaves are not properly disposed of, dangerous chemicals they contain could leak into the environment.
