Liftmaster 041D8613, WIRE HARNESS KIT - HIGH VOLTAGE
The LiftMaster 041D8613 high-voltage wire harness kit is used to replace the power-side harness inside compatible garage door opener motor heads. A high-voltage harness carries line-voltage power to the appropriate opener components, so the connector style, routing, insulation rating, and model-specific layout are important. This part is commonly associated with the LiftMaster 8160 garage door opener family and other applications only when the parts diagram specifically lists 041D8613 or 41D8613. It should not be confused with low-voltage harnesses used for wall controls, safety sensors, accessory wiring, or LED circuits. If the original harness is heat-damaged, cut, brittle, or modified, the rest of the opener should also be inspected for the underlying cause.

Technician Note
If the high-voltage harness failed from heat, arcing, pinched wiring, or water intrusion, replacing the harness alone may not correct the cause. Inspect the motor head, power input, outlet, transformer area, and board connections before returning the opener to service.
Before Ordering Checklist
- Match 041D8613 or 41D8613 to the exact opener parts diagram.
- Confirm this is the high-voltage harness, not the low-voltage harness.
- Compare connector count, wire colors, routing, and terminal locations.
- Inspect for board damage, heat marks, pinched wires, or loose terminals.
- Have a qualified technician handle high-voltage diagnosis or unsafe wiring conditions.
Professional Advisory
High-voltage garage door opener wiring can be hazardous. Disconnect power before service, do not modify harness connectors, and use a qualified garage door technician or electrician if there is any sign of burned wiring, damaged insulation, or improper power connections.
Product Questions and Answers
What opener is 041D8613 commonly associated with?
041D8613 is commonly associated with the LiftMaster 8160 opener family where the parts diagram lists this high-voltage harness.
Is this the same as a low-voltage harness?
No. 041D8613 is a high-voltage harness and should not be substituted for wall-control, sensor, or accessory harness wiring.
Can I splice the old harness instead of replacing it?
Splicing damaged high-voltage opener wiring is not recommended as a shortcut. Use the proper harness and have unsafe wiring inspected.
What should I check if the harness looks burned?
Check the board terminals, power input, outlet, transformer area, motor area, and any signs of moisture or pinched wiring.
Should a technician install this harness?
Yes, a qualified technician is recommended when working with line-voltage wiring or when the cause of harness damage is not clear.
