The Genie 39731R.S Circuit Board is a genuine OEM logic/control board designed to restore reliable operation to select Genie residential garage door openers. As the opener’s main controller, it manages motor operation, lighting, wall console inputs, wireless remote reception, and Safe-T-Beam safety sensor monitoring. Use this replacement part to resolve symptoms such as intermittent operation, failure to respond to remotes or wall controls, or diagnostic errors traced to a failed control board. The 39731R.S maintains the opener’s original features and security protocols (including Intellicode rolling-code remote functionality when applicable to the supported opener models) and is intended for use only on the Genie models specified by the manufacturer’s parts list.
Installation typically involves disconnecting power, labeling and transferring all wiring harnesses and terminal connections to the new logic board, mounting the board, and then restoring power. After installation, reprogramming is usually required: set open/close travel limits, adjust force as instructed by Genie, and relearn handheld remotes and any wireless keypad; verify Safe-T-Beam alignment and proper reversal on obstruction. For safety, always remove power before service, discharge static, and follow the opener’s service manual. Radio frequency and accessory compatibility are determined by the specific opener model that uses the 39731R.S; consult Genie’s official parts breakdown or your opener’s model/serial label to confirm fit before ordering. This OEM Genie replacement logic board is ideal for repair or upgrade of compatible Genie garage door opener systems in residential applications where dependable, manufacturer-approved performance is required.
