Abstract

A pair of door mounting assemblies mount an oven door assembly to an oven such that the oven door assembly may move between a closed baking position, a broiling position, and an open position. Each of the door mounting assemblies includes a mounting member that is pivotally connected to the door assembly. Each door mounting assembly includes a spring biased mechanism to enable the oven door assembly to be biased by the weight thereof when in a first range of movement, to be biased toward and into the broiling position when in a second range of movement, and to be biased toward and into the baking position when in a third range of movement. A damper assembly provides resistance to the movement of the oven door assembly within the second and third ranges to limit the rate of movement of the oven door assembly toward the broiling and baking positions.
