The Genie 27094A.S Limit Pinion is a genuine OEM replacement component for select Genie residential garage door openers. Positioned within the opener’s limit assembly, this pinion engages the limit gear to move the open and close limit cams, ensuring precise travel control so the door stops at the correct fully open and fully closed positions. Replacing a worn or stripped limit pinion can restore reliable door travel, reduce overrun issues, and prevent nuisance reversals. This part is commonly referenced in Genie parts diagrams as the “Limit Pinion” and is used on specific chain and belt drive models that utilize a cam-style limit system; always verify compatibility by matching the part number 27094A.S to your opener’s parts list or owner’s manual.
Installation typically requires removing the opener cover to access the limit assembly, transferring the pinion in the same orientation, and then resetting or reprogramming the travel limits per Genie instructions after power is restored. For safety, disconnect power to the opener before service and avoid working on door counterbalance hardware. This OEM Genie replacement part supports dependable limit operation in residential applications and is intended as a direct-fit service component rather than an aftermarket substitute.
