Open the door halfway by hand (release operator first) and let go of the door. The door should pretty much stay in the same position, although some slight drifting may occur. If the door wants to drop or if it opens on its own the garage door springs should be adjusted by trained and experienced garage door service technicians. To avoid possible severe injuries do not attempt to adjust the springs yourself – Contact us on 0161 477 3391 to schedule an appointment.
