The Marantec 104082 Control Board is an OEM replacement logic board for select Marantec residential garage door openers. It restores core operator functions by managing the motor drive, soft-start/soft-stop operation, open/close travel limits, force settings, courtesy lighting, wall control inputs, and photo-eye safety circuits. Designed to integrate with compatible Marantec radio systems and M3-series remote controls and keypads used by the corresponding operator, this control board is intended for use only in models that specifically call out part number 104082 in their documentation or on the original board label.
Use this replacement part to resolve issues such as intermittent operation, non-responsive wall stations or remotes, error codes related to the logic circuitry, or unreliable door travel. For correct fitment, match the part number 104082 on your existing board or consult the opener’s parts list. Installation should be performed with power disconnected; transfer all harnesses and terminal connections as labeled, mount the board as the original, then reprogram door travel and force limits and re-pair any transmitters using the opener’s learn/program function. After installation, verify safety sensor alignment and perform a full safety reversal test per the opener manual. This is a model-specific Marantec replacement part and is not universal.
