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.
On average, a microwave can last anywhere from 5 to 10 years with proper maintenance. However, many people may have microwaves that have surpassed that and are still working.
Microwave ovens typically have a lifespan of about 10 to 15 years, depending on usage and maintenance. After this period, they may still work, but their efficiency and safety can diminish. It's important to regularly check for signs of wear, such as unusual noises, arcing, or door seal issues.
The average microwave oven lasts about seven years with normal use, yet even less with heavy use and poor maintenance. A large family may find themselves replacing their appliance every four to five years as they become more reliant on its use to heat snacks and leftovers or to defrost meals.
On average, microwaves last 7-8 years.
For example, if the microwave cooks too slowly or quickly, it might need replacement. The best way to check it is by placing a cup of water and heat for 2 minutes. It should come out piping hot. If not, replace the appliance.
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.
It may be a damaged power cord, a bad fuse, or a malfunctioning circuit board – all of which are issues with the microwave itself. This microwave failure may also be from a natural cause. Have there been any power surges or storms near you? That can cook the wiring in your appliance.
Most microwaves last about 10 years, depending on their quality and how often you use them. Most microwaves last 1500 to 2000 hours but some low-quality microwaves last only 500 hours.
As the best microwave overall, we chose the Panasonic Microwave Oven; it combines a 1,200-watt motor with a compact exterior. If you're looking to save money and space, the Commercial Chef Countertop Microwave is the best budget microwave: simple but effective, much like microwave cooking itself.
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.
As a magnetron ages the emitted waveform becomes less pure and “splashy". This makes it less efficient.
A good rule of thumb is that if your appliance is more than ten years old, it may be time to buy a new one. However, if your microwave is newer, repairing it could be a better financial decision.
Yours will probably last about 10 years. But when it's time to replace it, you needn't spend much money on a new one. Most inexpensive microwaves are made by only a couple of manufacturers, so it doesn't make much difference which one you buy.
If you don't clean your microwave regularly, accumulated grime and food particles can cause performance issues. This buildup can affect how your microwave heats and operates, leading to inefficiency and potential damage. Make sure to wipe down the inside of your microwave frequently to remove any spills or splatters.
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.
Probably the most common issue of any microwave is when the plate doesn't turn. The turning plate helps cook and reheat your food evenly, so it's a major headache when it's not working. Usually, the problem could be from something obstructing the spinning assembly.
The most likely cause is that the diode, which increases the voltage to the magnetron, has burned out. If this is the case, then the magnetron can't receive enough power to generate microwaves. These can usually be replaced for a low cost.
One of the most common issues with a malfunctioning Magnetron is the lack of heating. If your microwave is running but not producing heat, it could be due to a faulty Magnetron, burned-out filament, or a malfunctioning high-voltage diode.
Newer models often come with energy-efficient options, preset cooking programs, and intuitive controls, making them more user-friendly and efficient than their older counterparts.
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.
But, if you are wondering if it's safe to use a burnt microwave, the answer is – it depends. If it just stinks, you can safely resume using it once it's cleaned. However, proceed with caution and consider buying a new appliance if any part of the microwave itself seems damaged or burned.
On average, a microwave can last between 9 to 10 years before it may need replacement. However, this can vary depending on the brand, model, usage, and maintenance. While older microwaves can still be safe to use, it's essential to inspect them regularly for any signs of wear and tear.
