WHAT limit switch????? Scwintek has no limit switch. The Brake release is NOT really a brake release. Once you do the so called brake release, it takes 3 or 4 people to manually push the room in or out. DID YOU PUT THE CONTROLLER IN OVERRIDE MODE? Code 8 or 9 on WHICH motor? for others--DO NOT REMOVE THE OUTSIDE MOTOR SCREW, IF YOU DO YOU WILL CAUSE THE MOTOR TO SPIN AND PULL THE WIRES OUT OF THE MOTOR AND POSSIBLY RUIN BOTH THE WIRE QUICK CONNECTS ON EACH WIRE END. You remove the screw and then LIFT the motors straight up about an inch to disengage from the drive shaft. Using a screwdriver to do that. Obviously you cannot do that if the system fails with the room retracted. Doug
