What causes the microwave plate to spin?
The microwave plate spins due to the design of the microwave oven, which includes a turntable motor underneath the glass plate. This motor is activated when the microwave is turned on and aids in evenly distributing the microwave energy throughout the cooking chamber. As the plate rotates, it helps to ensure that food is heated uniformly, reducing the chances of cold spots or overcooked areas.
Additionally, the spinning action helps to facilitate better cooking results by allowing the microwaves to penetrate the food from multiple angles. This is particularly beneficial for unevenly shaped items or large portions that may otherwise not cook thoroughly if stationary. The turntable feature is a standard in most residential microwave models.
Is it normal for the microwave plate to spin continuously?
Yes, it is entirely normal for the microwave plate to spin continuously while the microwave is in operation. This continuous motion is crucial for the cooking process because it promotes more even heating of the food. If the plate only moved intermittently, it could lead to uneven cooking and might leave certain parts of the food undercooked.
However, once the timer reaches zero or the cooking is complete, the microwave and the turntable motor should stop. If your microwave plate continues to spin without the heating function being active, it may indicate a malfunction, and you might want to consult the user manual or reach out to customer service for further assistance.
