The Useful Life of Microwave Ovens

Life Span

• Though the estimated life span of a microwave oven varies slightly from one source to the next, you may expect roughly 10 years of service from the average model. Gradually over time, microwave ovens weaken and their ability to properly heat food wanes, making replacement necessary. However, adding new parts to microwaves from time to time can help extend their life, though only a professional should handle repairs dues to radiation safety concerns.

Cleaning

• Though cleaning a microwave might seem like a solely hygienic act, it can help extend the working life of the machine. Splattered food that is not removed from the microwave's interior is cooked time and again when it's used, ruining the inside of the machine, according to ABC News. Also, grime in a microwave makes it less efficient at heating food, forcing it to work harder. Wipe down the interior of the microwave frequently and keep it spotless to ensure a long life.

Life-Extending Tips

• To keep a microwave oven working at full power for as long as possible and extending its life, little steps go a long way. Never run a microwave on empty, as the unabsorbed energy has damaging effects, according to the Lifespan website. Never leave microwave popcorn unattended, as it poses a fire hazard that can destroy the machine. Also, refrain from using tin foil or metal pans, which reflect microwaves, harming the oven.

Radiation Risks

• Though the radiation risk from a properly working microwave oven is minimal, one that has endured years of use requires examination. Small faults allow radiation to leak, necessitating the disposal of the machine even if it still works otherwise. Examine the door and seals of the microwave to ensure it shuts tightly and properly. Gaps and other problems allow radiation to seep out, creating a health hazard. Also, inspect the microwave's gaskets. If dented and worn, they may also leak radiation.
