The Genie 31057R.S Opto-Luctor is a genuine OEM replacement component for select Genie residential garage door openers that use an optical RPM sensing system. This part serves as the optical interrupter target for the opener’s sensor, allowing the control board to read motor rotation and maintain accurate travel, speed regulation, and safety reversing functions. Replacing a damaged or missing opto-luctor can help resolve issues such as erratic movement, unexplained stopping or reversing, and RPM-related error indications.
Intended as a direct replacement part, the 31057R.S Opto-Luctor is installed in the opener’s drive/motor area where it interfaces with the optical sensor. For best results, follow the service procedure in your Genie owner’s or service manual: disconnect power, access the drive compartment, install and align the opto-luctor so it spins freely through the sensor window, reassemble, restore power, and re-set limits if required by your model. Use only on compatible Genie units that utilize an optical RPM sensor; verify compatibility by model number in official Genie documentation before ordering or installing. Always follow all safety instructions and consult a qualified technician if you are unsure about repair steps.
