If your Genie garage door opener sounds like it’s running, but not moving, it could be a coupler. This is an easy fix! Used for attaching the screw of Genie screw drive rail to the motor head. This coupler is made to break away if the door hits a hard obstruction, thereby protecting the motor. If the motor of the screw drive Genie runs, but the screw is not turning, this coupler needs replacing. For Genie’s with split-rail screw drives, make sure you are looking at the rail screw nearest to the motor to determine the need for replacement.
