Abstract

A door ajar detection system is provided. The door ajar detection system may be incorporated in a refrigerator to provide a warning when a door is left in an open position, or to prevent a false door-closed detection. The system utilizes like magnetic poles of magnets positioned opposite to each other to push one or more doors in a refrigerator into a full open position such that a door ajar detection assembly may provide an accurate reading. A latch assembly may be provided to hold the one or more doors in a closed position against the force of the like magnetic poles.
