The LiftMaster 041K3796 Limit Sprocket Kit is a genuine OEM replacement part designed to restore precise travel control on compatible LiftMaster garage door openers. This kit replaces the worn or damaged limit sprocket that interfaces with the opener’s limit mechanism, ensuring the door reliably stops at the correct open and close positions. It is intended for select LiftMaster residential openers that use a mechanical limit system and helps eliminate over-travel, short travel, or erratic stopping caused by a degraded limit sprocket.
For proper fit, match 041K3796 to your opener’s parts list or owner’s manual. Installation typically involves disconnecting power, removing the opener cover to access the limit assembly, replacing the limit sprocket, and then resetting the travel limits (and force, if required) per the manufacturer’s instructions. Always disengage the door with the manual release and keep the door balanced during service; avoid adjusting door springs unless you are qualified. As an authentic LiftMaster replacement part, this limit sprocket kit supports dependable operation in residential applications and is a practical repair solution for owners seeking to maintain smooth, accurate door travel on select chain-drive or belt-drive models that specify 041K3796.
