Abstract
A door tensioning system for an oven or other appliance includes a chain and spring assembled as a pull member attached at one end to a door and at an opposite end to a base member of the appliance in a manner maintaining spring-mediated tension between the door and the base/bulk of the appliance. The pull member is routed around a bracket-assembly-mounted pulley, where the bracket assembly includes at least one movable bracket member that is movable with the pulley in a manner that will increase or decrease tension in the pull member by increasing/decreasing its effective length between its ends.
