Abstract
A microcomputer based monitor and display system for a refrigerator in which visual indicia are provided to indicate to the user the degree of door usage on a rolling average time basis. Threshold time limits are established to correspond to heavy, normal and light usage. The actual door-open time is sensed and accumulated in successive time segments. The rolling average door open time over a predetermined number of time segments is calculated at the end of each time segment and the appropriate lamp is lit depending on how the calculated average door-open time compares to the established threshold values.
