Liftmaster K1D6761-1CC Control Board

UL325 Replacement Logic Board for LiftMaster Commercial Openers The LiftMaster K1D6761-1CC (now K1D6761-1CCMC) is an advanced UL325-compliant logic board engineered to secure commercial-grade swing and slide gate systems. Purpose-built for LiftMaster SL3000U/UL, CSW200U/UL, SL585U/UL, and SL595UL models manufactured after 2016, it serves as the central processor that governs gate behavior, access authorization, and entrapment protection. By enforcing monitored safety zones - particularly in the OPEN direction - it elevates system resilience against operational failures and security breaches. Designed for maximum accountability in gated perimeters, this board also supports backward compatibility with earlier second-generation openers, provided the site is upgraded with compliant monitored photo eyes or edge sensors. Insecure or non-monitored configurations will result in non-functionality, reflecting LiftMaster’s full adherence to UL325 safety mandates. Key Features Built for Critical
