ABSTRACT:
A spring-powered turntable for use in a microwave oven includes microwave energy responsive assembly for automatically permitting rotation of the turntable when microwave energy exposure begins and for automatically turning off rotation of the turntable when microwave energy exposure ceases. The microwave energy responsive assembly can be located between a rotating part of the turntable and a non-rotating part of the turntable. The microwave energy assembly can include a material that expands or contracts when exposed to microwave energy and serves to control a brake for braking the rotating part of the turntable.
