The Sommer S11931 Synoris 800 Motor Carriage is the genuine OEM replacement traveler for Sommer Synoris 800 direct drive garage door opener systems. Also known as the motor carriage, drive carriage, or trolley, this moving module contains the drive mechanism that glides along the rail’s stationary chain to open and close the door with the low-vibration, quiet performance Synoris is known for. Use it to restore reliable operation when the original carriage becomes worn or inoperative on residential or light commercial Synoris 800 installations.
This S11931 assembly is designed specifically for the Synoris 800 and is not a universal substitute for other Sommer models. Proper installation typically involves disconnecting power, releasing the door, removing the rail end cap, sliding out the old carriage, inserting the new unit, reconnecting wiring, and then running the setup procedure to re-learn travel limits and pair remotes per the Sommer manual. For safety, only use with a properly balanced door and functional photo-eyes, and consult a qualified technician if spring or door adjustments are needed.
