Closet door came off rollers

[sheelister]

Half of the closet door has jumped off its rollers/slider.
Anyone have hints as to how to get it to jump back on? As you know, it's very heavy, so it feels like a daunting project.
Thanks for any suggestions.

I had a 2016 38RL that the front closet door came off the glide....

It was actually real easy to place it back up, just line it up, and roll it on...

Going forward, there was a single piece of thin metal 90* angle iron bracket screwed into the ceiling acting as a door stop... that flimsy piece broke and allowed the door to roll off..

I got a thicker, more Heavier Duty 90* bracket and placed 2 of them next to each other.... problem solved
