Abstract
A warming chamber defining a heated internal cavity is presented having a door that may be opened or closed to provide access to the cavity for the storage of, for example, food products. The chamber includes a temperature sensor that sends signals to a control regarding the sensed temperature within the cavity. The control then activates heating elements when necessary to maintain the cavity at a predetermined temperature. The control further senses when the door has been opened, and supplies a power boost to the heating elements in anticipation of a cooling effect even though a temperature drop within the cavity has not yet been sensed.
