The LiftMaster 41C5497 High Voltage Wire Harness is an OEM replacement harness designed for select LiftMaster residential garage door openers. This factory-assembled wiring harness carries line power from the power source to the opener’s high-voltage components, restoring safe, reliable operation when the original harness is damaged, heat-stressed, or worn. It is intended for use only on compatible models that specifically list 41C5497 in their parts diagrams or service literature, including many LiftMaster and Chamberlain openers with equivalent assemblies, as well as certain Sears Craftsman units built by Chamberlain. As a genuine part, it maintains correct connector geometry, lead lengths, and color coding for the designated opener family, helping ensure proper routing and strain relief inside the chassis.
Installation involves removing power from the opener, matching the keyed connectors to their original mating points, and routing the harness along the factory paths and clips to prevent pinching or abrasion. No programming is required; however, work on high-voltage circuitry presents shock and fire hazards, so service should be performed by a qualified technician and only after verifying the harness part number against the opener’s model-specific parts list or wiring diagram. Use with the opener’s rated line voltage and follow all safety instructions on the product label and in the manufacturer’s manual. This LiftMaster 41C5497 High Voltage Wire Harness is an ideal OEM replacement part for garage door opener repair, delivering a direct-fit solution for compatible residential chain or belt drive units.
