{"product_id":"liftmaster-k1d8247","title":"LiftMaster K1D8247 Hall-Effect Sensor Board — CSW200U \/ CSW200UL","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K1D8247 is the Hall-effect sensor board identified in documented CSW200U and CSW200UL swing-gate operator service information. It belongs to the operator’s internal feedback arrangement and is separate from the main logic board, power board and external entrapment sensors. Match the full model and installed revision before ordering. A feedback-related symptom can originate in the board, wiring or drive movement, so the repair should follow diagnosis of the complete sensing path rather than replacement based on a fault indication alone.\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\u003eCSW200U\u003c\/td\u003e\n\u003ctd\u003eManufacturer service information identifies this board.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSW200UL\u003c\/td\u003e\n\u003ctd\u003eVerify the current drawing and installed revision.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSL3000 encoder arrangements\u003c\/td\u003e\n\u003ctd\u003eDo not substitute K2A0878 or another sensor by appearance.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOlder Omni control generations\u003c\/td\u003e\n\u003ctd\u003eRequire their own service reference verification.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal protection devices\u003c\/td\u003e\n\u003ctd\u003eDifferent function; this is not a photo eye or gate edge.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eDiagnose Feedback and Mechanical Movement Together\u003c\/h2\u003e\u003cp\u003eA feedback fault can occur when the sensing circuit, its connection or the associated mechanism does not operate correctly. Have the technician inspect these together and preserve diagnostic information. A stalled motor or binding gate can prevent expected movement even if the sensor itself remains serviceable. Replacing electronics does not repair that mechanical cause.\u003c\/p\u003e\u003cp\u003ePhotograph the installed board and its connections before service. Compare the actual assembly with the appropriate CSW200 drawing, especially if previous repairs changed the control system.
