The Genie 36220A.S Sprocket Belt Drive is a genuine replacement component for select Genie belt‑drive garage door openers. Positioned at the top of the motor head, this sprocket engages the drive belt to transfer motor power to the rail system, restoring smooth and consistent door travel when a worn or damaged sprocket causes slipping, noise, or erratic movement. It is intended for Genie belt‑drive residential openers that specifically list 36220A.S in their parts diagram; always confirm compatibility against your opener’s model number and parts list before ordering.
Installation typically involves disconnecting power, removing the opener’s head cover, releasing belt tension, swapping the sprocket, re‑tensioning the belt, and then checking or reprogramming travel limits and force settings per the opener manual. After installation, verify proper operation and test safety systems, including photoelectric sensors and the door’s auto‑reverse function. Using the exact Genie part number helps ensure proper fit and performance for users searching terms such as Genie sprocket, belt drive sprocket, garage door opener replacement part, and OEM Genie belt drive component.
