LiftMaster 041C5499 High Voltage Wire Harness Kit

LiftMaster 041C5499 High Voltage Wire Harness Kit

The LiftMaster 041C5499 is a one-piece high voltage wire harness replacement kit for select LiftMaster and Chamberlain AC chain drive and belt drive garage door openers. It is used inside the opener head for factory line-voltage wiring connections.

This harness should be matched by the original part number, opener model, and plug layout before installation.

What This Part Does

The 041C5499 harness carries internal power connections through the opener head. A worn, heat-damaged, or loose harness may cause no-power symptoms, intermittent operation, burning odor, or unreliable power delivery.

Because similar symptoms can be caused by the logic board, wall outlet, motor, capacitor, or incoming power, diagnosis should be performed before replacing the harness.
