The Marantec 97798 Control Board is an OEM replacement logic board for select Marantec residential garage door openers. As the central controller, it manages the motor drive, travel limits, force settings, lighting, soft-start/soft-stop behavior (where applicable), wired wall control inputs, photoelectric safety sensors, and the pairing of wireless accessories. Installing a new 97798 board is a common remedy for symptoms such as no response from the opener, erratic operation, persistent error codes, or failure to learn remotes. This genuine Marantec replacement part is engineered for compatibility with specific models only; always confirm fitment using your opener’s model/serial information and the manufacturer’s documentation before purchase.
For installation, disconnect power to the operator, transfer all harnesses and accessory connections to the same terminals on the new board, and follow the opener’s manual to reprogram travel limits and force. If your system uses a plug-in radio receiver, move it to the new board or re-pair remotes via the unit’s learn function as directed by Marantec. After setup, verify safety sensor alignment and perform a full UL 325 reversal test with the door. The 97798 control board supports typical residential applications and is intended to restore original performance and safety functionality when replacing a failed or damaged logic board. Compatibility, wiring, and programming steps can vary by opener model; consult official Marantec technical documentation for exact procedures.
