Product Overview
The Genuine LiftMaster 045DCT Circuit Board is an OEM replacement designed to fully restore the performance of select LiftMaster DC chain and belt‑drive garage door openers using Security 2.0 technology (yellow Learn button). It features built‑in MyQ capability for use with compatible MyQ accessories, and for non‑Wi‑Fi operators it supports added internet/app control through the LiftMaster 828LM Internet Gateway. This control board manages DC motor output, integrates with standard photo-eye safety sensors and wall controls, and installs as a direct-fit replacement—simply disconnect power, transfer wires one‑to‑one, mount the board, then reprogram remotes, keypads, and travel limits while handling the assembly as ESD‑sensitive. Designed to operate within openers powered from 120VAC, 60 Hz, this listing includes the 045DCT control board only (no housing, wiring harnesses, lamps, rails, motor, remotes, or accessories), and dimensions are not specified by the manufacturer but fit the original opener housing.
Main Features
- MyQ capability: works with MyQ accessories; for internet/app control add LiftMaster 828LM Internet Gateway if Wi‑Fi is not built in
