On mine there are two nylon latch/sliders on each door on the bottom. The nylon part needs to be slid up to release the bottom of the door from the track. They are kind of tight but will snap up. Then just pull the bottom of the door out a bit and lift the top rollers out of the track. Piece of cake.
