How to you remove patio door to replace roller

This is usually a 2 person job. Most patio doors are made with a spring loaded roller on the bottom which carries the weight of the door and holds it in the tracks. One person lifts the door to remove pressure on lower spring roller while second person uses a tool (usually a flathead screwdriver but a knife will work too) to lift the roller up from the track. Then swing the lower half of the door free of the track. Lower the door until it rests on the ground (floor, etc) and the top half will be free. Installation is opposite.

Depends on manufacturer.

On the inside of stationary door at the jamb end there should be 2 stops that are screwed to door. Remove these stops and door should lift out.

On the rolling door at the bottom at each end there is a slot. Using a Phillips screwdriver to raise the rollers to lower door. Lift door out.

Chuck

Not an easy 1 person job since the door is heavy especially double glass. ZLift the moveable panel up as far as possible and carefully pull the bottom out.
