The LiftMaster 41C5498 Low Voltage Wire Harness is a genuine OEM replacement harness used to connect the opener’s control board to low-voltage accessories such as the wall control and safety reversing sensors. Designed for select LiftMaster residential garage door openers, this factory-terminated harness helps restore reliable communication across the opener’s low-voltage circuits, resolving issues caused by damaged plugs, broken leads, or intermittent connections. It is ideal for maintenance or repairs where the original harness has been compromised and is often referenced in LiftMaster parts diagrams and service manuals by its part number.
This replacement harness features pre-fitted connectors for correct polarity and secure mating with the opener’s logic board and accessory terminals, supporting the low-voltage control lines used by photo eyes and wall stations. Compatibility is model-specific: use only with operators that explicitly list 41C5498 in their manual or parts list. For installation, disconnect power, remove the opener cover, note the routing path, unplug the old harness from the control board, plug in the new harness, and route it as shown in the manufacturer’s documentation, keeping wires clear of moving components. After installation, verify proper operation of the wall control and test safety sensor alignment and obstruction reversal per LiftMaster and UL 325 guidelines. This OEM wire harness is a direct-fit replacement part for buyers searching for a LiftMaster low voltage harness, logic board harness, or safety sensor/wall control wiring repair on compatible chain- or belt-drive residential openers.
