A hinge assembly for removably mounting an oven door on the front wall of the cabinet of a food processing oven for movement between open and closed positions with respect to the oven cavity includes a hinge plate mounted in overlying relation with respect to the front wall at one side of the oven cavity, a hinge arm on which the oven door is removably mounted pivotally attached to the hinge plate, a support arm joined pivotally at one end to the hinge arm and extending into the oven cabinet alongside the oven cavity through an aperture in the hinge plate and an aligned aperture in the front wall of the oven cabinet and a spring attached at the opposite end of the support arm and cabinet frame, to bias the oven door to a "closed door" position. The hinge assembly includes the improvement of a permanently affixed stop to prevent damage to the front wall of the oven cabinet after the door is removed from the hinge arm, because of engagement by the hinge arm if the latter is pulled forcibly by the biasing spring toward the front wall. The stop includes a pin mounted on and extending transverse the support arm for engagement with the hinge plate prior to the hinge arm engaging the front wall of the cabinet. The stop pin is ineffective to engage the hinge plate when the oven door is mounted on the hinge arm.
