A system for measuring and monitoring the closure of a refrigerated compartment of an appliance comprising: a controller (200;202) having at least one input and at least one output for receiving and providing electrical signals to a plurality of electrical components of said appliance; a user interface operatively coupled to said controller; a pressure sensor for monitoring said compartment having an output representative of compartment pressure operatively coupled to an input of said controller; said controller configured to: monitor said pressure sensor output to detect the presence of a negative pressure pulse indicative of a compartment closure; compare said negative pressure pulse magnitude to a target pressure pulse magnitude; provide an indication of an improper compartment closure if said negative pressure pulse differs from said target pressure pulse by a predetermined amount; characterized in that the controller is further configured to create a calibration pressure profile by monitoring a predetermined number of closures and storing a predetermined number of pressure parameters measured by said sensor, thereby creating a target pressure profile, wherein said pressure parameters include the average magnitude of the pressure pulse indicated by said sensor, the average duration of the pressure pulse, and the return time required for the compartment to return to ambient pressure. a controller (200;202) having at least one input and at least one output for receiving and providing electrical signals to a plurality of electrical components of said appliance; a user interface operatively coupled to said controller; a pressure sensor for monitoring said compartment having an output representative of compartment pressure operatively coupled to an input of said controller; said controller configured to: monitor said pressure sensor output to detect the presence of a negative pressure pulse indicative of a compartment closure; compare said negative pressure pulse magnitude to a target pressure pulse magnitude; provide an indication of an improper compartment closure if said negative pressure pulse differs from said target pressure pulse by a predetermined amount; characterized in that the controller is further configured to create a calibration pressure profile by monitoring a predetermined number of closures and storing a predetermined number of pressure parameters measured by said sensor, thereby creating a target pressure profile, wherein said pressure parameters include the average magnitude of the pressure pulse indicated by said sensor, the average duration of the pressure pulse, and the return time required for the compartment to return to ambient pressure. monitor said pressure sensor output to detect the presence of a negative pressure pulse indicative of a compartment closure; compare said negative pressure pulse magnitude to a target pressure pulse magnitude; provide an indication of an improper compartment closure if said negative pressure pulse differs from said target pressure pulse by a predetermined amount; characterized in that the controller is further configured to create a calibration pressure profile by monitoring a predetermined number of closures and storing a predetermined number of pressure parameters measured by said sensor, thereby creating a target pressure profile, wherein said pressure parameters include the average magnitude of the pressure pulse indicated by said sensor, the average duration of the pressure pulse, and the return time required for the compartment to return to ambient pressure.
