Do microwave ovens lose power as they age?
We're convinced that our 18 year old built-in microwave is losing power over time.
Things take longer to heat up than they used to.
Is this a thing? Is there an explanation for it that might inform a repair?
Answer:
It is possible for a microwave oven to lose power over time, which can result in longer heating times. There are a few potential explanations for this issue:
-
Magnetron wear: The magnetron is the component in a microwave oven responsible for generating the microwaves that heat the food. Over time, the magnetron can wear out or weaken, which can result in decreased power output. If this is the case, replacing the magnetron may help restore the microwave's performance.
-
Aging electrical components: The electrical components within a microwave, such as capacitors or diodes, can deteriorate over time, leading to reduced power output. If these components are faulty or nearing the end of their lifespan, they may need to be replaced to restore the microwave's performance.
-
Power supply issues: Problems with the electrical outlet or the power supply to the microwave can also cause reduced power output. Ensure that the microwave is receiving the proper voltage and that the outlet is functioning correctly. It may be helpful to test the microwave with a different outlet to rule out any issues with the power supply.
If you suspect that your microwave is losing power, it is recommended to have it assessed by a qualified appliance repair technician. They will be able to diagnose the specific cause of the issue and provide guidance on whether a repair is feasible or if it would be more practical to consider a replacement.
Keep in mind that microwaves, like other appliances, have a finite lifespan, and after 18 years of use, it may be reaching the end of its expected service life. In some cases, the cost of repairs may be significant compared to the value of a new microwave, so it's worth considering the potential costs and benefits of repair versus replacement.
