Why does my microwave spin when I open the door?
The reason a microwave continues to spin even when the door is opened is due to the design of the appliance. Microwaves are equipped with a turntable that rotates to ensure even cooking of the food placed within. When the door is opened, some models maintain the rotation as part of keeping the microwave’s mechanics intact, avoiding any abrupt stops that could cause wear or damage to the components.
However, it’s important to note that while the turntable might continue to spin, the microwave’s internal magnetron, which generates microwave radiation, shuts off automatically once the door is opened. Therefore, while the turntable might give the impression of ongoing operation, it is harmless as the actual cooking process is halted.
Is it safe for my microwave to spin when the door is open?
Yes, it is safe for your microwave to continue spinning with the door open. The turntable’s rotation serves no functional purpose in terms of cooking since the microwave’s internal functions are disabled by an interlock system that prevents radiation emission. The interlock is designed to ensure that microwave energy does not escape the appliance, so you can safely observe the spinning turntable without any risk.
Moreover, the continuous spinning motion does not pose any physical threat or hazard since the microwave is not operating in terms of heating or cooking when the door is ajar. This protective design allows for the turntable to remain in motion solely for mechanical reasons.
