The Genie 38647R.S Circuit Board is a genuine OEM logic/control board for select Genie residential garage door openers. As the central controller, it manages motor operation, travel limits, force settings, Safe-T-Beam photo-eye monitoring, wired wall console input, and the integrated radio receiver for Genie Intellicode remotes on compatible models. Replacing a failed control board with the 38647R.S can restore normal opener function when symptoms include unresponsive wall control or remotes, erratic operation, or diagnostic LED indications pointing to logic board faults. This factory-spec replacement part is designed to fit designated Genie openers without modification, preserving original performance and safety features.
Compatibility for the 38647R.S is model-specific and not universal; verify by matching the opener’s model number and the existing board’s part label to Genie’s official parts list before ordering. Installation requires disconnecting power, transferring the existing wiring to the same terminals, mounting the board, and then reprogramming travel limits, force, and Intellicode transmitters (and wireless keypad, if equipped). After setup, confirm Safe-T-Beam alignment and perform required UL 325 safety reversal tests. For North American residential applications on 120 VAC, use a grounded outlet and follow the opener’s service instructions; if you are unsure of fit or programming steps, consult the Genie owner’s manual or the manufacturer’s parts cross-reference for 38647R.S.
