My guess is that the rolling wheels need to be replaced so I watched a how to video from Swisco on how to remove the door. I'm not sure the bottom track just pops out on this version the same way that it does on your video.
I've attached a few photo's, perhaps you can identify the door type and if the door removal is the same or if there is a different video or set of instructions to remove the door.
Also, can you recommend the required parts to purchase from you for this repair?
Thanks very much for your help!
