Liftmaster 041D7356-5 Receiver Logic Board Assembly (Tri-band) 1-1/4HP
The LiftMaster 045DCT125 is a receiver logic board replacement kit for select 1-1/4 HP LiftMaster and Chamberlain garage door openers. It is part of the Security+ 2.0 yellow learn button opener generation and is tied to higher-horsepower residential opener applications where the standard 045DCT board may not be the correct part.
The key fitment issue with this board is the 1-1/4 HP application. Similar-looking logic boards can share the same general Security+ 2.0 technology but differ by horsepower, opener platform, harness connection, feature set, and board number. This part is commonly cross-referenced as 041D7356-5, 41D7356-5, 1D7356-5, and 001D7656-5, and some catalog references tie it to HD930EV style opener searches.
Replace this board when the original board number and parts diagram confirm it. Common symptoms can include failed remote programming, no accessory response, logic malfunction, or visible board damage after sensors, wall controls, travel module, and power have been checked. Do not choose this board only because the opener has a yellow learn button; the horsepower and original board number matter.
