Installation of the door gasket was fairly easy. Door is very light and I recommend you remove it. A cordless screw driver or drill set to the lowest resistance setting is recommend as there are approximately 32 sheet metal screws tucked under the molding. Almost thought I could do it with the door still on, but the angle of the bottom was tricky and gravity pulled the gasket down. Make sure the screws go through the pre-cut holes in the gasket. I missed a couple originally. Taking the door off made it easier to see where the gasket was not in alignment or where I had missed the pre-cut holes. A second set of hands is nice when taking on or off the door.
