“Microwave Oven Lifespan: How Long Do Microwave Ovens Last?”

Oven Lifespan


If you’re looking for the lifespan of a microwave oven, or just want to learn a little more about what goes on inside one, this guide is for you. Microwaves are one of the most common appliances in American kitchens, but they do have a tendency to break down after just five to seven years. We’ll take some time to explore how long microwaves last and why they fail (Spoiler alert: It’s rarely because of their age). We’ll also discuss other common problems with microwaves—and how you can extend the life of your favorite appliance.

Microwave oven lifespan.

Microwave ovens are a staple in most kitchens. They’re used to heat up food, but they can also be used for other purposes like defrosting meat and making popcorn.

Despite their popularity, many people don’t know how long microwave ovens last or even how long they should last before having to be replaced. If you’re wondering how long your microwave will last, read on!

How long does a microwave last?

While there is no standard life expectancy for microwaves, the average lifespan is 5-7 years. This can be extended by taking good care of your appliance and following the manufacturer’s instructions for maintenance.

How long your microwave lasts depends on how much you use it and how well you care for it. A more expensive model with better quality parts will typically last longer than a cheaper model with less reliable components. Additionally, if you don’t take proper precautions when using your microwave (and especially if someone else uses it without knowing what they’re doing), then its lifespan may be shortened significantly as well!

Parts of a microwave oven.

Microwave ovens are made up of several components. The main oven itself is where you place your food to heat it up, but there are also other parts that help make that happen. The door is an important part because it protects the interior from dust and prevents children from reaching into it. The control panel allows you to select cook times and other settings for your microwave recipes, while the turntable rotates food inside the microwave so that all sides can be cooked evenly (or not). A trim kit covers up any gaps between cabinet doors and countertops when installing new appliances in older homes or apartments where kitchens were not originally designed with built-in appliances in mind. An exhaust fan sucks out hot air from inside this appliance so that it doesn’t build up inside its housing unit; this helps keep both yourself safe while using this kitchen tool as well as reducing energy usage by preventing excess heat buildup within its walls! Finally: Magnetrons create microwaves which then pass through waveguides before entering into our foods’ molecules – changing their molecular structure so we can enjoy tasty treats without spending hours preparing them ourselves!

How often should you replace your microwave?

If you use a microwave oven daily, it may be time to replace the unit after five years. If you don’t use it very often but still want to keep your food fresh, then replacing it every seven years is recommended. If you use a microwave frequently (say once a week), then three years would be about right for replacement purposes as well.

Common problems with microwaves.

  • Overheating. Microwaves heat food by creating electromagnetic waves that vibrate the molecules in your food. If you turn your microwave on for longer than necessary, it can overheat and damage its internal components.
  • Fan motor. The fan motor circulates air throughout the oven cavity to keep temperatures consistent across all parts of the interior, which helps prevent burning or drying out foods during cooking. If this part breaks down, food will take longer to cook because heat isn’t distributed evenly throughout the chamber–and it might also start smelling bad!
  • Thermostat/thermocouple assembly (TCA). This little device measures the temperature inside your microwave and tells it when to shut off so as not to overcook anything inside–a very important function! If this piece malfunctions or fails completely then try replacing it before buying another appliance altogether; having two working TCAs is better than none at all!

Extended warranty considerations.

Extended warranties are a great way to protect your microwave oven and ensure that it will last as long as possible. The best part is, they’re not too expensive! The average price for an extended warranty is $10 to $20 per year, which means you can easily afford it with just one or two extra dollars per month.

For example, if you buy a cheap microwave from Walmart for around $50 and then pay $2 per month for an extended warranty, that’s only 24 months of coverage–and after those two years are up (and assuming nothing breaks), there’s no reason why your new microwave wouldn’t still be working fine without any additional protection from third parties like us here at Microwave Ovens For Sale Online Incorporated (MFO). But if something does go wrong with your appliance during those first 24 months of ownership…well…you’ve probably already lost money by now anyway because things break so often these days! So what do we do? Buy another one? Or maybe wait until next year when newer models come out? Or perhaps even buy yet another one later down the road when sales start going up again?

Microwaves have a tendency to break down after five to seven years, but they can also last up to 10 years if you’re lucky!

If you’re wondering how long your microwave oven will last, there are a few factors that will determine its lifespan. The most important one is whether or not it’s installed properly and maintained regularly. If you take good care of your appliance and repair any problems before they become severe enough for the warranty company to deny coverage, your microwave should last longer than seven years–and possibly even up until its 10th birthday!


We hope that this article has given you some insight into how long your microwave oven is likely to last. It’s important for everyone to know that microwaves are not built to last forever, but there are steps you can take to prolong their life and save yourself from having to replace it too soon. For example, we recommend getting an extended warranty if one is available at the time of purchase because they cover repair costs if something breaks down within a certain period of time (typically three years). Also keep in mind that replacing parts such as door seals or fans will help extend its lifespan too!
