The supplier identifies manufacturer reference K41-0073-000MC, while manufacturer parts drawings use the base reference K41-0073-000. Confirm the supplied revision against the exact operator before ordering. This is the main control board, not the separate HD power board or brushless motor-drive board. Replacing the correct component depends on identifying the original fault and matching the complete service reference.\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\u003eHDSL24UL\u003c\/td\u003e\n\u003ctd\u003eManufacturer repair diagram identifies K41-0073-000 as the main board; verify the supplied MC revision.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDSW24UL\u003c\/td\u003e\n\u003ctd\u003eManufacturer service-parts guide identifies the same base main-board reference; confirm the actual equipment revision.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eINSL24UL \/ IHSL24UL\u003c\/td\u003e\n\u003ctd\u003eManufacturer manual lists the base control-board reference, but motor-drive parts differ; confirm approved service selection.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard DC pad-mount or linear-actuator boards\u003c\/td\u003e\n\u003ctd\u003eDifferent service references; do not select this board merely because the operator uses 24V DC.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eDistinguish Main Control, Power and Motor-Drive Electronics\u003c\/h2\u003e\u003cp\u003eThe heavy-duty operator contains several electronic assemblies with different jobs.
