I loosened middle hinge by the 2 screws which holds a power cord that clips together, then slid the hinge flap upward to release from the door. My bottom clip hinge was broken away from spring and the only way to attach a new hinge clip was to carefully separate the hinge flap. This can be done by squeezing the flap to see where the separation seams are. Small narrow screwdrivers along with a spatula will do without damaging the plastic. This allowed for acess
to the spring which connects to a small hole in top of hinge clip. Be sure that hinge clip snaps in position before closing up flap. Clip power cord back together, slid hinge clips over mounts, reattach middle hinge and you're done
