The LiftMaster 050DCTWF is an OEM replacement logic/circuit board for select LiftMaster DC-motor residential garage door openers with integrated myQ and Wi‑Fi. This control board manages door movement, Safety Reversing Sensor inputs, Security+ 2.0 radio reception, and smart-home connectivity, restoring full functionality when the original board fails. With built-in 2.4 GHz Wi‑Fi, it supports myQ app control for remote operation, status alerts, and scheduling, and includes the Security+ 2.0 encrypted receiver (yellow Learn button) for compatibility with current LiftMaster transmitters and keypads. The Security+ 2.0 tri-band receiver operates on 310/315/390 MHz for robust range and reduced interference.
Designed for LiftMaster openers that specifically call out part 050DCTWF in their documentation, this DC logic board is commonly used in W‑series DC chain/belt models with integrated Wi‑Fi (for example, 8160W/8160WB—always verify your opener’s parts list or the label on your existing board before ordering). It is not a substitute for AC‑motor logic boards such as 050ACTWF. Installation requires disconnecting power (and any battery backup), moving the terminal leads and harnesses to the matching connectors on the new board, then reprograming travel limits, force settings, and Security+ 2.0 remotes/keypads. Complete myQ setup through the myQ app on a 2.4 GHz network (802.11 b/g/n). For safety and UL 325 compliance, photoelectric sensors must be present and aligned; the board will not allow normal operation without them. Compatible with Security+ 2.0 accessories like 891LM/893LM remotes and current wireless keypads, and intended for North American residential openers rated for 120 VAC, 60 Hz input. Always consult your opener’s manual for model-specific procedures and compatibility.
