The Genie 39354R.S is a genuine OEM replacement belt assembly for Genie belt-drive garage door openers configured for a 7-foot residential sectional door. Designed to restore smooth, quiet operation, this factory-specified belt transfers drive power from the opener to the trolley for reliable everyday use. It is intended for units that originally shipped with part number 39354R.S and a 7-foot door configuration, making it a direct-fit service part for repairing worn, stretched, or damaged belts on compatible Genie belt-drive systems.
This replacement part is not universal and is not for chain- or screw-drive models; confirm compatibility by matching 39354R.S to your opener’s parts list or the identification on the existing belt/rail assembly. For doors taller than 7 feet, use the correct Genie extension kit and corresponding belt specified by the opener’s documentation. Installation typically involves relieving belt tension, routing the belt around the drive and idler, reconnecting to the trolley, and adjusting tension per Genie’s instructions; after installation, re-set travel limits and force and verify Safe-T-Beam operation. Disconnect power and secure the door before servicing. Using the correct OEM Genie belt helps maintain the opener’s intended performance and noise level in residential applications.
