The LiftMaster K1D8389-1CCMC is an OEM UL325 main control board replacement kit designed for LiftMaster® DC pad-mount commercial and residential gate operators manufactured after 2016. Engineered for service, repair, and replacement applications, this control board restores core operator functionality including gate logic control, monitored safety input management, radio communication, and accessory integration.
Designed as a direct OEM replacement part, the K1D8389-1CCMC is compatible with multiple LiftMaster® UL325-compliant slide and swing gate operators. The board is also backwards compatible with select second-generation gate operators when properly configured with required monitored entrapment protection devices.
For UL325 compliance, monitored photoelectric safety sensors or monitored edge sensors are required on the OPEN entrapment zone when used with compatible operators. Always verify compatibility using the operator installation manual or replacement parts diagram prior to ordering.
