How Does a Microwave Work?
A microwave uses electromagnetic waves to heat food. These waves excite water molecules in your food, generating heat quickly and evenly. If you want a more detailed explanation, you can read this guide on how microwave ovens work.
Key components include the following:
Magnetron – produces microwave radiation
Turntable – rotates food for even heating
Control panel – lets you set time and power
Door switch – ensures safety during operation
If any of these parts fail, your microwave may stop working properly.
