In 1947, Raytheon built the "Radarange", the first commercially available microwave oven. It was almost 1.8 metres (5 ft 11 in) tall, weighed 340 kilograms (750 lb) and cost about US$5,000 ($68,000 in 2023 dollars) each.
1945: American engineer Percy Spencer filed a patent for the first microwave after noticing a chocolate bar melting in his pocket whenever he was close to a cavity magnetron tube. 1946: The RadaRange, the first commercial microwave, was sold to restaurants, ship galleys and canteens.
As long as it is functioning well (door still attached, no build-up of dried food around the door frame, electrical parts insulated, etc.), it is safe to use indefinitely. Why would you think otherwise? A microwave oven simply heats the food using...
1946: The first commercial microwave—the RadaRange— is sold by Raytheon to restaurants, large canteens and ships' galleys. It was nearly six feet tall, weighed more than 750 pounds, used about 3,000 watts of power and sold for roughly $5,000. 1967: The first microwave for residential use comes to market.
Raytheon released the “Radarange,” the first commercially available microwave oven, in 1947. According to Raytheon, they cost between $2,000 and $3,000 and were stored in refrigerator-size cabinets.
Under contract to Whirlpool, Westinghouse, and other major appliance manufacturers looking to add matching microwave ovens to their conventional oven line, Tappan produced several variations of their built-in model from roughly 1955 to 1960.
In 1955, the Tappan Stove Company—under a licensing agreement with Raytheon—brought the first consumer microwave ovens to the U.S. market with a price tag of $1,300.
Also available were microwave ovens, ranging in price from $189.95 to $439.95. Of course, there's been a good deal of dollar inflation since 1975. Judged by changes in the consumer-price index, what $100 bought in 1975 takes about $354 to buy today.
Most microwaves are built to last up to 10 years.
Don't Toss Out Your Broken Microwave
Because of their electrical components, microwave ovens are considered e-waste in some places, and improper disposal will get you some serious fines and/or into a bit of legal trouble.
With normal usage for an average family and good maintenance, a microwave often lasts for 7 to 8 years. If the microwave is used less frequently by a single person or a couple and is well-maintained, the lifespan can increase to up to 10 years.
And of course, as technology becomes commonplace, the price goes down as well. In 1990 a much-smaller microwave with two power levels could be purchased for $99.98, which amounts to about $183 in today's money.
If microwave ovens are used while broken or altered, it is possible for them to leak electromagnetic radiation. Microwave radiation leaks are hard to detect because you can't smell or see microwaves.
Older microwaves may not have the most updated safety features or may have weakened over time, making them potentially dangerous to use.
In 1980 the price of a microwave oven was 450andCPIwas82. Todaythepriceofamicrowaveovenis 100 and CPI is 259. Round to two decimal places The 1980 price of a microwave oven measured in today's dollars is 1,098.90.
Before the modern microwave, preparing hot food meant slow cooking, roasting, heating or steaming food in the oven or on the stovetop. Microwaves are now a staple of modern kitchens, making it quick and easy to reheat, cook or even crisp meals and snacks in a matter of minutes.
You want your food being cooked, not you! Microwaves older than 10 years or with faulty doors should be replaced immediately in order to reduce radiation exposure while you cook.
On average, microwaves last 7-8 years.
“All the door strikes, latch mechanisms, and door switches themselves are plastic, so slamming the microwave door can physically break any of these components,” says Chris Zeisler, technical service supervisor at RepairClinic.com.
Those microwave ovens were huge, nearly six feet tall and more than 750 pounds, and cost $5000 — the equivalent of more than $50,000 in today's currency. The first countertop home model went on sale in the 1950s for a more affordable $495, and by 1997, fully 90% of U.S. households owned a microwave oven.
Small models start around $60, and midsized models are typically in the $100 to $400 price range. OTR microwaves can be had for under $200, but most we test cost $500 and up.
Our survey team recommends that you repair any higher-end OTR microwave that's 4 years old or less and consider repairing one that's 5 to 7 years old. Replacement is recommended for any OTR microwave that's 8 years or older.
In 1967, Amana brand began selling the first countertop microwaves for around $500, and by 1970, nearly 40,000 units were sold. By 1986, about one in four American homes owned a microwave, and by 1997, the U.S. Bureau of Labor Statistics reported that nine out of every ten American homes had a microwave.
The tubes in the magnetron had to be water-cooled, so plumbing installation was required. Result: The first microwave oven weighed about 750 pounds and was nearly 6 feet tall.
The 1960s brought microwave ovens to the consumer market, but most households could not afford this somewhat mysterious appliance. In 1967, the “Amana Radarange” was introduced at a still-steep price tag of about $500.
