The Genie 39340S.S Circuit Board is an OEM replacement logic/control board designed for select Genie residential garage door openers. This assembly serves as the “brain” of the opener, managing motor control, travel limits, force detection, Safe-T-Beam system monitoring, and radio reception for handheld remotes and wireless keypads. Installing a new control board can restore normal operation in units exhibiting symptoms such as intermittent operation, loss of remote response, erratic lights, or failure to run after power events. When paired with compatible Genie models, it supports Intellicode rolling-code security and standard Genie accessories including Safe-T-Beam safety sensors and multi-function wall consoles.
Use this replacement part when the original control board has failed or been damaged. For installation, disconnect power to the opener, transfer all harnesses and connectors one at a time to the new board, and handle components carefully to avoid static discharge. After replacement, follow the opener’s owner’s manual to reprogram travel limits and force settings, and re-learn remote controls, keypads, and HomeLink/Car2U if applicable. Compatibility is model-specific—always match by part number on the existing board or verify against the opener’s service documentation and Genie’s official parts lists. This genuine Genie control board is intended for residential garage door opener applications and requires properly aligned Safe-T-Beam sensors for normal door movement per safety standards.
