1. A door assembly comprising:
a door including a striker;
a first door actuator mechanism positioned proximate a top of the door to transition the door between an open position and a closed position;
a second door actuator mechanism positioned proximate a bottom of the door to transition the door between the open position and the closed position;
a first latch positioned at a first location around a perimeter of the door and engaging with the door to hold the door in the closed position; and
a second latch positioned at a second location around the perimeter of the door and engaging with the door to hold the door in the closed position, the second latch comprising:
a cam having a cam surface, and
a biasing member coupled to the cam, the biasing member being configured to transition the cam between a first position in which the cam surface is urged against the striker to prevent the cam moving over center to transition the door to the open position, and a second position in which the cam is urged against the cam surface and moves over center such that the cam surface disengages the striker to permit the door to transition to the open position, wherein:
the second latch is further configured to transition to the cam to the second position in response to the door opening.
