The Genie 30257T.S Screw Drive Coupler is a genuine OEM replacement component for Genie screw-drive garage door openers. Positioned between the motor output and the screw-drive rail, this coupler transfers torque from the motor to the screw, enabling the carriage to move the door smoothly. Replacing a worn or broken coupler can resolve symptoms such as the motor running while the screw does not turn, intermittent movement, or excessive vibration. It’s intended for residential Genie screw-drive systems and is not used on chain or belt-drive models. This part is commonly searched as a screw drive coupler, motor coupler, or drive shaft connector for Genie openers, and is identified by part numbers 30257T and 30257T.S.
Installation typically involves disconnecting power to the opener, releasing the door using the emergency release, removing the opener cover, swapping the old coupler, and aligning the coupler with the motor shaft and screw-drive input before reassembly. After installation, the opener’s travel limits may need to be checked and adjusted per the owner’s manual. For compatibility, confirm your opener’s model and parts list to ensure it specifies 30257T.S, as couplers are model-specific within Genie’s product family. Follow all safety precautions, including disconnecting power and supporting the door, during service.
