Liftmaster 41DCCC3A Receiver Logic Board Assembly Tri-band Chamberlain 315MHz
The LiftMaster 045DCT is a replacement receiver logic board for select Security+ 2.0 garage door openers. It is used in compatible residential DC chain drive and belt drive opener heads and manages the opener logic, accessory learning, remote communication, and control functions tied to the board. It is commonly found in yellow learn button opener families made after 2011.
This board is often tied to LiftMaster 8360 Premium Series chain drive and 8550 Elite Series belt drive models, plus related Chamberlain and Sears Craftsman openers from the same DC motor platform. Search references also connect it with Chamberlain HD920EV, LW5000EV, WD962KEV, WD962KPEV, WD962MLEV, and 349544 model families. Compatibility should still be verified by parts diagram because LiftMaster/Chamberlain used multiple similar boards across AC, DC, Wi-Fi, battery backup, and lock-capable models.
Common replacement reasons include failed remote programming, no response from accessories, intermittent logic board issues, board damage, and control faults after the wall control, safety sensors, travel module, and power source have been checked. After installation, remotes, keypads, travel limits, and force settings may need to be reset according to the opener manual.

Technician Note
A 045DCT board is not automatically correct for every yellow learn button opener. Check the exact opener model and original board number, especially when replacing boards in Wi-Fi, lock-capable, or 1-1/4 HP units.
Before Ordering Checklist
- Match the original logic board number.
- Confirm the opener model and manufacturing date.
- Confirm DC chain or belt drive application.
- Check whether the opener requires Wi-Fi/myQ, battery backup, or lock-capable board support.
- Be prepared to reprogram remotes, keypad, travel limits, and force after replacement.
Professional Advisory
Disconnect power before servicing opener electronics. If the board has burn marks, water damage, or repeated failures, inspect the power source and opener wiring rather than simply replacing the board again.
