What Is a Microwave Oven’s Lifespan? The Debate – Repair vs. Replacement


Microwave ovens have come a long way since they were first introduced. Yet, microwaves today still have relatively short lifespans compared to those of other common kitchen appliances.

How long do microwaves last? Is a microwave repair worth the money? Mr. Appliance® has the answers.

How Long Is a Microwave’s Lifespan?

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. This lifespan can be shortened even further if the wrong items are placed inside, which may cause irreparable damage or a risk of fire.

Some microwaves, particularly those from higher-end brands such as Wolf and Viking, tend to last longer, around 10 to 15 years or even more. The lifespan of these microwaves can be further enhanced by repairing them when issues arise.

Should You Repair or Replace Your Microwave?


At some point, your microwave will need to be replaced, but in many cases, a repair may be the more cost-effective option. The experienced professionals at Mr. Appliance can help make your decision easier with these tips on which small appliances are worth being repaired.

In general, if you can repair your microwave rather than replace it, that will prove more cost-effective in the long run.

Five Tips to Make Your Microwave Last Longer

Maximize your microwave’s lifespan with these tips:

  1. Ensure there is adequate air circulation around the microwave.
  2. Use a surge protector to safeguard the electrical components.
  3. Neve place metal objects inside the microwave.
  4. Use a gentle soap and water for cleaning.
  5. Do not turn the microwave on when empty.

Five Signs That You May Need to Replace Your Microwave


  1. Cooking times are off. If your food cooks too quickly or too slowly, test your microwave’s power by placing one cup of water inside and turning it on for two minutes. If the water isn't piping hot when removed, it may be time to repair the unit.
  2. The door seal is compromised. The door seal is an important safety feature designed to contain low levels of radiation. This element of a microwave oven is something that should be handled with a repair job instead of a full microwave replacement.
  3. Issues with the keypad. If one or more buttons on the keypad are not responsive, it may significantly hamper the functionality of your microwave. If a good cleaning doesn't resolve the issue, call Mr. Appliance for microwave repair services.
  4. Old age. If your microwave is approaching the 10-year mark, consider replacing it with a new, energy-efficient unit.
  5. Odd smells. Odd odors, such as a burning smell, smoke, or sparks, are a sign something is amiss, and you should immediately turn off and unplug the microwave and call for a repair.
