Microwaves are an essential appliance in modern households, providing quick and convenient heating for leftovers, frozen meals, and beverages.

They have become an integral part of daily life for many people, but some may wonder how long these appliances typically last and what factors can affect their lifespan.

In this blog post, we will explore the lifespan of microwaves, the factors that can impact their longevity, and tips for extending their lifespan.

All in, it’s about how long do microwaves last since day you own one.

History of Microwaves

Microwaves are a ubiquitous appliance in modern kitchens, but their history dates back to the early 20th century.

The development of the microwave oven is attributed to Percy Spencer, an American engineer, who accidentally discovered the heating effect of microwaves in 1945.

Spencer was working on a radar system when he noticed that a candy bar in his pocket had melted.

After conducting further experiments with food, Spencer realized that microwaves could be used to heat food quickly and efficiently.

The first commercial microwave oven was introduced in 1947, but it was large, expensive, and intended for commercial use only.

It wasn’t until the 1960s that smaller, more affordable microwave ovens became available for home use.

By the 1970s, the microwave had become a staple in many American households.

Today, there are countless brands and models of microwaves available to consumers.

They come in a variety of sizes and styles, from countertop models to built-in units.

Despite their widespread use, many people are unaware of the factors that can affect the lifespan of their microwave.

Proper usage and maintenance can help extend the lifespan of a microwave. Overheating, using metal objects, and failure to clean the unit can all contribute to a shortened lifespan.

Signs that a microwave is going bad include strange noises, uneven heating, and a lack of power.

Safety concerns associated with old or aging microwaves include the potential for fire or electrical hazards.

It is important to replace a microwave if it is showing signs of wear and tear or if it is more than 10 years old.

Technological advancements, such as inverter technology and improved insulation, can contribute to a longer lifespan for modern microwaves.

Studies have shown that the average lifespan of a microwave is around 9 years, but proper usage and maintenance can help extend this lifespan.

When it comes time to dispose of a microwave, it is important to consider environmentally friendly options.

Many retailers offer recycling programs for old appliances, and some cities have programs for curbside pickup of large items.

Lifespan of Microwaves

Microwaves, like any other appliance, have a limited lifespan.

The average lifespan of a microwave is around 7 to 9 years, according to data from the National Association of Home Builders.

However, many microwaves can last much longer with proper care and maintenance.

This is according to the experts at Mr. Appliance, who have been in the appliance repair business for over 20 years.

A study conducted by Consumer Reports found that the best microwaves can last up to 10 years, while lower-end models can last as little as 5 years.

Signs of Microwave Aging

There are several common signs that indicate a microwave may be reaching the end of its lifespan, including:

1. Unusual noises during operation

2. Longer cooking times

3. Inconsistent heating

4. Burnt or overcooked food

5. The door or control panel becomes loose or damaged
