The LiftMaster 041D9204 Wire Harness is a genuine OEM replacement wiring assembly for select LiftMaster garage door openers. It is designed to restore reliable connections between designated internal components and the opener’s logic board, helping maintain consistent operation after the original harness becomes worn, damaged, or develops intermittent connections. The assembly features factory-terminated, keyed connectors for a direct, plug-in fit within compatible LiftMaster units, making it a practical replacement part for repair and maintenance of residential openers.
This part is not universal; verify compatibility by checking your opener’s parts diagram or service manual for part number 041D9204. Installation typically involves disconnecting power, opening the operator housing, routing the harness through the built-in channels and retainers, and mating the color-coded, keyed plugs to their matching headers on the control board and associated components. Avoid pinching wires during reassembly and test operation after power is restored. A simple harness replacement normally does not require reprogramming; if the control board has also been serviced, complete the learn/limit routines per your opener’s instructions. For safety, disconnect power before service and consult a qualified technician if you are unsure.
