When Should You Replace Your Microwave Oven?

Most people agree that you should replace your microwave every ten years. Of course, you may need to replace it sooner if you notice signs that it's not working well anymore. Some brands may last longer than others too. For instance, General Electric (GE) microwaves are known to last up to ten years and often longer.

There are several reasons why you'd need to replace your microwave before its lifespan is up. The main reason this appliance will die sooner than you may think it will is overusing it. The more often you cook with your microwave, the faster it will die.

Many people don't know what to look for when their microwave is dying. Luckily, this article will discuss the things you can look out for.

How To Know When Your Microwave is Dying

There are seven signs that will help you know when to replace a microwave oven, or at least know if it is on its way out. The first is how old it is. If it's over ten years old, it's more than likely near the end of its useful life. But age isn't the only indicator that it's time to replace microwave ovens. Other ways to tell if your microwave is dying is if:

  • It doesn't cook your food as well as it used to
  • The microwave door doesn't close properly
  • It makes loud and obnoxious noises while running
  • You smell a burning smell when it's running
  • You see sparks when turning it on
  • It starts smoking

Smoking and sparking microwaves can be alarming. These signs can often lead to small house fires. So, if you see these, you need to stop using your microwave immediately. According to the National Fire Protection Agency, these appliances cause about 4% of all house fires associated with cooking.

While this number is relatively low compared to other cooking fires, no one wants to experience this, and it's easily preventable if you can watch for the warning signs.

If you experience one or more of these warning signs with this appliance, it's time to consider a new microwave.

Light Bulb Failure

An easy and common microwave repair is changing a faulty lightbulb. It’s likely the lightbulb will go out before the microwave does. You can purchase light bulbs for reasonable prices and replace them yourself without hiring a professional.

Microwave Door Won’t Close

The door not closing correctly can warrant a repair or replacement depending on a few situations. If the door isn't locking correctly, but there are no other issues with your appliance, then repairs are worth it. If the door doesn't close correctly and other signs accompany that it's dying, then replacement is best.

Microwave Repair Cost

The cost of a microwave oven repair will vary. On average, repairs cost anywhere from $50 to $400 according to Angi.com. This includes parts and labor. Most microwaves aren’t all that expensive, so it may be possible that the cost of repair is higher than the value of your microwave. Evaluating how much the repairs will cost can help you determine whether it's worth it to buy a new microwave or spend money on costly repairs.

Since you can get affordable microwaves for under $50 at most big-box stores, you may be more interested in purchasing a new one. On the other hand, if you have an expensive and high-quality microwave, you may want to try repairs first before replacing it.

A critical factor in how much it will cost to repair your microwave is if you're doing it yourself or hiring a professional. You can save money by doing it yourself, but hiring a professional for any appliance repair is almost always a better choice for safety reasons.

Rest assured that microwaves are generally one of the more affordable appliances to repair. Microwave repair parts tend to be cheaper than dishwasher parts or parts for convection ovens.

Traditional Microwave vs. Convection Microwave Oven

Most people lump microwaves and convection microwaves into the same category, and for the most part, they're very similar. Convection microwaves have all the same abilities as a traditional microwave, but they also have an additional fan to help cook food using different methods.

They can bake, roast, and crisp, while a traditional microwave will heat food using radiation heat transfer. If you have a convection microwave oven, you still need to replace your microwave every seven to ten years.

As convection microwave ovens have more features and capabilities than standard microwave ovens, they also come with additional components: a heating element and a fan to circulate hot air and allow even cooking. Additional features, parts and capabilities can result in more expensive repair costs.

FAQs

Should I replace my 20-year-old microwave?

It depends. Most people need to replace their microwave once they reach seven to ten years old. But if you've taken care of your microwave that's 20 years old and there are no signs that it's dying, then you don't have to replace it.

Do microwave ovens get weaker with age?
