Abstract: A door status detection system is provided for use in a refrigerator having a cabinet defining first and second food storage compartments and corresponding first and second doors hingely mounted to the cabinet for selectively closing the compartments. The doors each include a magnetic sealing strip secured thereto for sealing the doors to the cabinet and for maintaining the doors in closed position. First and second switch arrays are installed into the cabinet generally adjacent a section of the magnetic sealing strips of the first and second doors, respectively, when the doors are in closed position for signaling the opened/closed status of the doors. The first and second switch arrays are electrically connected in series and operated by the magnetic sealing strips of the doors. Circuitry is connected to the first and second switch arrays for signaling a user of the refrigerator if either of the doors remains in an opened position for a defined period of time.
