Abstract: A power operated system for raising and lowering an oven rack but without opening the oven door is disclosed. The system comprises a plurality of conventional rectangular wire oven shelves in a spaced apart relationship. Each shelf is supported on a protuberance that has a threaded portion that rides up and down a threaded support bar. The support bar is turned by a continuous loop chain gear that derives it's direction from an electric motor. The electric motor is controlled by a remote located switch on the face of the oven. The support bars form a right-angle frame within the oven cavity and are oriented above a lowermost section of the oven which houses the electric motor and the journal bearings they are in.
