LiftMaster 41A5507-6C Receiver Logic Board Assembly

The LiftMaster 41A5507-6C Receiver Logic Board Assembly is an original OEM replacement control board for select LiftMaster and Chamberlain residential garage door openers. This board houses the opener’s microprocessor and built‑in radio receiver, restoring reliable operation when symptoms include intermittent running, non‑responsive remotes, or erratic control. It manages core functions such as motor control, door travel and force logic, and compatibility with standard LiftMaster safety reversing sensors, while supporting Security+ rolling code radio controls for remotes and keyless entry systems.

Compatibility for the 41A5507-6C is model‑specific; always match the exact part number printed on your existing board and verify the learn button color/frequency of your opener to ensure correct pairing with your remotes. Installation requires disconnecting power, transferring wire harnesses and terminal leads to the same positions, and then reprograming travel limits, force settings, and re‑learning remote controls/keypads per the opener’s manual. Use proper ESD handling, ensure safety sensors are present, aligned, and functional, and do not substitute this board for Security+ 2.0 (yellow learn button) or other non‑matching frequencies. Designed for North American residential operators that plug into 120V AC, this LiftMaster 41A5507-6C receiver logic board assembly is a dependable OEM replacement part for restoring safe, consistent garage door opener performance.
