DOOR ALARM SYSTEM AND REFRIGERATION DEVICE
Door alarm systems, methods, and apparatus are disclosed. A door alarm system may monitor a door of a refrigeration device and detect a failed attempt at closing the door. In response to detecting the failed attempt, the door alarm system may generate a notification of the detected, failed attempt so that remedial action may be taken.

21 . A method, comprising:
detecting, via one or more sensors, a movement of a door indicative of an attempt to close the door; and
generating a notification, via a controller, if the attempt to close the door failed.
22 . The method of claim 21 , wherein the method comprises:
determining that the attempt to close the door failed according to an angle of the door and a closed position of the door.
23 . The method of claim 21 , wherein the method comprises:
determining that the attempt to close the door has commenced according to an angle of the door and a threshold angle of the door.
24 . The method of claim 21 , wherein the method comprises:
determining the attempt to close the door failed according to the rate of change of an angle of the door.
25 . The method of claim 21 , wherein the method comprises:
determining that the attempt to close the door failed according to a distance between a current position of the door and a closed position of the door.
26 . The method of claim 21 , wherein the method comprises:
determining that the attempt to close the door has commenced according to a distance between a current position of the door and movement of the door toward a closed position.
27 . The method of claim 21 , wherein generating the notification comprises sounding an audible alarm.
28 . The method of claim 21 , wherein generating the notification comprises sending an electronic message selected from a group of electronic messages comprising an email message, a short message service (SMS) message, an instant message and a push notification.
29 . A system, comprising:
one or more sensors configured to detect a movement of a door; and
a controller coupled to the one or more sensors, wherein the controller is configured to:
determine, according to the movement of the door, whether an attempt to close the door failed to close the door; and
if the attempt failed to close the door, generate a notification that indicates that the door failed to close.
30 . The system of claim 29 , wherein the controller is configured to:
determine that the attempt to close the door failed according to an angle of the door and a closed position of the door.
31 . The system of claim 29 , wherein the controller is configured to:
determine that the attempt to close the door has commenced according to an angle of the door and a threshold angle of the door.
32 . The system of claim 29 , wherein the controller is configured to:
determine the attempt to close the door failed according to the rate of change of an angle of the door.
33 . The system of claim 29 , wherein the controller is configured to:
determine that the attempt to close the door failed according to a distance between a current position of the door and a closed position of the door.
34 . The system of claim 29 , wherein the controller is configure to:
determine that the attempt to close the door has commenced according to a distance between a current position of the door and movement of the door toward a closed position.
35 . The system of claim 29 , comprising:
a speaker; and
wherein the controller is configured to generate the notification by sounding an audible alarm via the speaker.
36 . The system of claim 29 , wherein the controller is configured to generate the notification by sending an electronic message selected from a group of electronic messages including an email message, a short message service (SMS) message, an instant message, and a push notification.
37 . A controller for a door alarm system having one or more sensors that detect a movement of a door, the controller comprising:
one or more ports communicatively coupled the one or more sensors; and
a processor operable to:
determine, according to the movement of the door, whether an attempt to close the door failed to close the door; and
generate a notification that indicates that the door failed to close.
38 . The controller of claim 37 , wherein the processor is operable to:
determine that the attempt to close the door failed according to an angle of the door and a closed position of the door.
39 . The controller of claim 37 , wherein the processor is operable to:
determine that the attempt to close the door has commenced according to an angle of the door and a threshold angle of the door.
40 . The controller of claim 37 , wherein the processor is operable to:
determine the attempt to close the door failed according to the rate of change of an angle of the door.
