If you take good care of your microwave up into its old age, there's a low risk of harm, but if it's damaged in any way you may want to get it checked out. If you've looked after it well, there's no reason why a vintage microwave should be dangerous.
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?
Microwaves older than 10 years or with faulty doors should be replaced immediately in order to reduce radiation exposure while you cook.
A good microwave will last approximately seven years. Of course, there are many variables to consider that can affect this. The more often you use it the shorter the life is likely to be, as is misusing it by putting inappropriate items in it.
If you're not sure if your microwave has been damaged, you can test it by putting a microwave-safe container with water inside and then running it for a minute. If the water isn't hot, the microwave has been damaged. If the microwave still heats, it hasn't been damaged and can still be used safely.
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.
If your microwave is still in good working condition, but simply lacks the latest features, you may want to hold off on purchasing a new one. However, if your microwave is exhibiting signs of wear and tear, or if it is over ten years old, then it may be time to consider upgrading to a newer model.
Rent a Dumpster for Your Old Microwave
Or, consider reaching out to a local housing charity or homeless shelter to see if they can accept your microwave. Simply clean it and take it to the place of your choice, whether that's a local non-profit or national organization.
If the sounds of your microwave start to change significantly, moving from a whir or hum to loud buzzing or rattling, this can be an indication of a serious problem. You should have even more cause for alarm if your microwave begins emitting smoke or sparks, or if smells like it is burning.
"Microwaves alter the taste of food, take up a lot of room and make nearly everything mushy," she says. Nicole Robina, a publicist, agrees with Shortt that conventional ovens are the way to go. "Everything tastes better when you heat it up in the oven," she says. "It's worth the extra time."
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.
As a magnetron ages the emitted waveform becomes less pure and “splashy". This makes it less efficient. In Radar terms a splashy magnetron has to be replaced immediately For cooking purposes the chicken will still get cooked but maybe not as quickly.
Factors to Consider
Age of the Microwave: Microwaves typically last about 7 to 10 years, so if yours is in the 7-year range or older, repairs might only offer a temporary fix, making replacement the better long-term option.
Microwave's Internal Issue
Components like the magnetron (the device that produces microwaves) or the high voltage capacitor might be malfunctioning, causing a spike in power consumption, and tripping the circuit breaker.
You can test if your microwave is heating properly by heating a cup of water in a microwave-safe dish for about 30 seconds. Carefully test the water to see if it has heated. If it isn't hot, repeat the process. If it still isn't hot after a few attempts, it is not heating properly.
Typically, magnetron tubes wear out and need replacing for approximately every 2,000 to 8,000 hours of operation. Due to their varying lifespan, which mostly depends on use, we offer brand new magnetrons and rebuilt tubes. Magnetron tubes are critical components in your microwave system.
If you take good care of your microwave up into its old age, there's a low risk of harm, but if it's damaged in any way you may want to get it checked out. If you've looked after it well, there's no reason why a vintage microwave should be dangerous.
Smoke, sparks, and burning smells.
These are signs of a serious and urgent problem. Stop what you're doing, and turn off and unplug the microwave immediately. There's no going back if you see smoke or sparks, or smell something burning.
Our survey results suggest that you should consider repairing the broken microwave if it's still under warranty or if it's 5 years old or less, but you'll definitely want to replace it if it's more than 5 years old.
The average microwave oven lasts about seven years with normal use, yet even less with heavy use and poor maintenance.
Retail Store Programs: Many major retailers like Best Buy, Staples, and Office Depot have in-store electronics recycling programs that may accept old microwaves, though policies can vary by location 5 7.
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.
The life expectancy of an oven varies depending on the type of oven you own. The life expectancy of an electric oven is around 13 - 15 years. The life expectancy of a gas oven is around 15 years. The life expectancy of a dual-fuel oven is also around 15 years.
According to Consumer Reports, these magical appliances typically last around nine years. That number can vary, depending on how often you use it and the brand. Though microwaves can be repaired, it's often more cost effective just to get a new one and send your old one to be recycled.
To avoid replacing yours more than about once every 10 years—which is how long most manufacturers tell us they should last—you'll want to take care of it. Your microwave may not get as grimy as your oven, but even so, one of the best ways to keep it humming along is to keep it clean.
