How Long Should a Microwave Last? Tips to Make It Last Longer
The microwave has become a requisite kitchen appliance. It can do everything from reheating leftovers to defrosting dinner in a matter of minutes. However, like any appliance in your home, it will not last a lifetime.
Knowing how long a microwave should typically last can help you plan for repairs or replacement before it ultimately fails at the worst time possible. In this guide, we will discuss average microwave lifespan, important factors affecting microwave lifespan and basic maintenance tips that may keep your microwave functioning for years.
Average Lifespan of a Microwave
Usually, microwaves last somewhere from 7 to 10 years with daily household use. Length of time left when using a microwave can vary depending on:
Frequency of use – if it is used heavily every day, it might meaningfully shorten the life of a microwave.
Build quality – High-end builds can often last much longer.
Maintenance – keeping a microwave clean, not using metal inside, and avoiding misuse can help increase the life span.
Generally, commercial uses in restaurants or offices will land around 4 to 6 years with heavy use.
Signs You to Need to Get Your Microwave Repaired
It may not necessarily be time to throw away a microwave that starts having issues. Many times, a quick repair can prolong the life of the appliance, and help you save money.
Below are some of the most common signs that your microwave may need servicing by a professional:
1. The Turntable Stops Rotating
If your food is not heating evenly, then you may want to check to see if the turntable is turning. There may be a broken motor, the coupling is worn, or there is debris under the roller ring. This may be a simple and easy fix in some instances, but if the problem continues to occur, it may be time to get a technician.

2. Unusual Noises While Running
A humming sound is normal for most microwaves, while loud buzzing, grinding, or rattling can indicate a problem with the motor, magnetron, or internal fan. Ignoring these such noises can result in more serious and more costly issues.
3. Food Takes Longer to Heat
If your microwave is suddenly taking a long time to warm up your food, it may mean that the magnetron or high-voltage capacitor is failing. These parts are responsible for generating heat in the microwave. If they are bad, they will need to be replaced.
4. The Door Doesn’t Close or Seal Properly
A loose or broken door latch is more than just irritating. It is a safety issue. Microwaves are designed to only work when the door is fully closed to ensure there is no leakage of radiation. Repairs for this should not wait.
5. The Control Panel Malfunctions
Unresponsive buttons, flickering displays, or settings changing by themselves are signs of electrical or circuitry issues. Minor electrical glitches sometimes can simply be reset to recover from the issue. If it repeats, you probably need servicing.
6. Burning Smell or Smoke
A burning smell or smoke during operation is a warning sign. It could originate from food remnant, broken wires or failed internal component. Turn off the microwave and have it checked.
7. Sparks Inside the Microwave
Sparks (also called arcing) could happen if metal gets inside, but if it occurs without metal present, it may indicate a damaged waveguide cover or failed internal component. This should be taken care of soon to avoid being damaged more.
