Select it from the exact operator parts list and any applicable manufacturer correction before ordering. It is separate from the main logic board, transformer and motor. Similar-looking boards and a shared single-phase designation do not establish interchangeable fit. Have the technician diagnose the power and motor-control circuit and confirm the original board label so the replacement matches the actual equipment generation.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSL3000UL, 2018 UL325 manual\u003c\/td\u003e\n\u003ctd\u003eLiftMaster support identifies K1D8402-1CC as the corrected single-phase power-board reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented CSW200501U assembly\u003c\/td\u003e\n\u003ctd\u003eManufacturer repair drawing lists K1D8402-1CC; confirm the installed generation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK1D8284-1CC in older drawings\u003c\/td\u003e\n\u003ctd\u003eDo not rely on the older reference without checking the manufacturer correction.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMain logic board K1D6761-1CC\u003c\/td\u003e\n\u003ctd\u003eSeparate from this power-board service item.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThree-phase and DC operators\u003c\/td\u003e\n\u003ctd\u003eNo compatibility established by similar board appearance.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eMatch the Correct Power Board to the Operator\u003c\/h2\u003e\u003cp\u003eLiftMaster’s support page for the 2018 SL3000UL manual explicitly corrects the motor-drive\/power-board part number to K1D8402-1CC. The referenced CSW200501U repair drawing also identifies this part. Verify the exact operator and original board before purchase, particularly where an older printed manual shows a different number.
