The Marantec 116422 Control Box is an OEM replacement controller for select Marantec garage door openers. This factory part houses the opener’s logic and control electronics that manage motor operation, soft start/stop, travel limits, work light control, and safety circuits. It connects to standard safety photo-eyes, wall stations, and compatible Marantec radio accessories, restoring reliable door operation when a failed controller causes intermittent movement, non-responsive remotes, or error codes. As an original Marantec component, it is designed specifically for the Marantec operator models that list 116422 in their parts diagrams; always match the part number on your existing unit or confirm with the manufacturer’s documentation for compatibility.
Installation typically involves disconnecting power, transferring harness connections and accessory wires to the new control box, and then performing the opener’s setup steps such as reprogramming travel limits and force settings and re-pairing hand-held transmitters if required by the model. For safety, follow UL 325 practices: verify proper photo-eye alignment, test the reversal system, and ensure correct wiring polarity on low-voltage terminals. Use this Marantec 116422 Control Box as a direct replacement part or upgrade for residential garage door opener repairs where the original controller is damaged by surges, moisture, or age, and consult the product manual for model-specific programming procedures.
