LiftMaster 041C4876 Wire Harness Kit
The LiftMaster 041C4876 wire harness kit is an internal replacement wiring harness for select older LiftMaster and Chamberlain belt drive garage door openers. The harness routes factory connections between internal opener components, so connector shape, wire count, and opener generation are critical to correct fitment.
LiftMaster lists 041C4876 as discontinued with no compatible replacement. That makes this part especially important to verify before ordering or uploading because another LiftMaster harness may not plug into the same board or accessory locations. A harness that looks close in photos may still be wired differently.
This part is commonly searched when a belt drive opener has damaged internal wiring, intermittent power, loose connectors, or a harness damaged during other repairs. Harness failure should be separated from logic board failure, transformer failure, photo eye wiring issues, and wall control wiring problems before parts are replaced.

Technician Note
Because this harness is discontinued and there is no direct LiftMaster-listed replacement, confirm the part from the opener manual or the original harness label before ordering. Do not cut and splice a different harness to make it fit.
Before Ordering Checklist
- Confirm the opener is a compatible belt drive unit
- Match the original part number to 041C4876 or 41C4876
- Compare connector count, connector shape, and wire routing before installation
- Do not substitute a high-voltage, low-voltage, or dual-light harness unless the parts diagram says it is correct
- Disconnect power and inspect the logic board for burn marks before replacing harnesses
Professional Advisory
Internal opener wiring can involve line-voltage and low-voltage circuits inside the same chassis. If the old harness is burned, melted, or damaged by water or pests, a qualified garage door technician should inspect the opener before reconnecting power.
Important Ordering Warnings
- LiftMaster lists this part as discontinued with no compatible replacement
- Connector layout matters; do not rely on wire color alone
