If you look in the corner(once you separate the latch from door), 1 or two of slits - [ will be visible. and next to that you will see, gray tabs which slide up and down. Using a thin screw driver, align those tabs next to the slits [ . once it's aligned, push the latch and it should start operating.. This is sort of temporary fix because with repeated use, it may get stuck again and you will have to repeat the process. Hope this works.
THERE SHOULD BE RECALL ON THIS.
I, too, am having the same problem, on pretty much the same model. I have alrady discovered amd implemented the same temporary fix. It lasted only 1 week before coming apart a seond time. There's apparantly an issue here.
