I am not familiar with your rig but I have a similar problem on my HR. Mine will require completely removing the door to relocate the upper hinge. I have, with a little experimentation, discovered that if I push in on the upper part of the door above the latch, as I operate the latch, it operates as it should. Not looking forward to the repair but it will be done before next spring. Best of luck.
