The coupler assembly connects the garage door opener motor to the screw drive rail assembly. If the motor on your garage door opener is running, but the screw is not turning, it is most likely time to replace the screw drive coupler with this replacement. If you glance up at the rail when you press the garage door opener button, you will be able to hear the motor run and see if the screw that is inside the rail is turning.

QUESTIONS & ANSWERS

Ask a Question
  • Will this coupler fit model 3060 36645RS

    No, Genie model 3060 requires the coupler 30257T.S.

  • Will this fit a Genie GX9000? I can’t find ANY information on this model

    No, the Genie model GX9000 does not have a coupler assembly, instead it uses a clutch.  Can you verify that your motor is running but the screw is not turning?  If so you can try disengaging the door with the door closed.  Then hold a flat headed screwdriver in the back of the motor head screw slot and turn the white clutch nut with a wrench to the right, start with a half of a turn.  Re-engage and retry the operation, if it helps you can repeat as needed. Please let us know if you need further help.
