Abstract
An oven having one or more low-temperature self-cleaning modes has an interior cavity and at least two heating elements in the interior cavity. A sump is formed in the bottom wall of the cavity. The oven has an electronic control unit, which activates and deactivates the heating elements during operation of the low-temperature self-cleaning mode. The electronic control unit may disable an oven door lock during a low-temperature self-cleaning mode.
