Hi all. one of my Liftmaster SCS300K arms to my driveway gates keeps getting "stuck" whilst the other side works perfectly. Sometimes the "sticky" arm is delayed a few seconds compared to other arm and ends up only partially open. Other times, it does not open at all and I have to attempt to open/close the gates 2-3 times before it responds. When it does respond, it sometimes opens fully and other times opens only partially. I have tried lubricating to no avail. Any suggestions? Help much appreciated.
