This is a model-specific replacement for the original 12V platform, not a universal board for every LiftMaster gate with a 12V battery. Match the full operator model, installed board number and wiring diagram before ordering. Keep the radio receiver and its frequency identification separate from the main-board selection, because a compatible control board alone does not establish compatibility with every existing remote.\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\u003eLegacy RSL12V \/ RSW12V\u003c\/td\u003e\n\u003ctd\u003eMatch the applicable manufacturer service drawing and installed board.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVH and other suffix variants\u003c\/td\u003e\n\u003ctd\u003eConfirm the complete model and specific replacement reference before ordering.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLater VDC \/ U \/ UL models\u003c\/td\u003e\n\u003ctd\u003eNo automatic interchangeability established from a shared RSL or RSW name.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSL24 \/ CSW24 controls\u003c\/td\u003e\n\u003ctd\u003eDifferent platform; a similar connector or enclosure does not establish fit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExisting radio receiver\u003c\/td\u003e\n\u003ctd\u003eIdentify its separate module and frequency before assuming remote compatibility.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003ePreserve the Existing System Identification Before Replacing Controls\u003c\/h2\u003e\u003cp\u003eAn unresponsive operator does not necessarily have a failed main board. Battery condition, charging supply, damaged wiring, an active protection input or a mechanical fault can produce similar symptoms. Have a qualified technician diagnose the complete system before ordering electronics, and record the original settings and connected accessories while the installation can still be identified.\u003c\/p\u003e\u003cp\u003eThe legacy documentation identifies radio modules separately from the main controller. K001A6636 and K001A6636-1 are distinct radio references, so retain the full module label rather than recording only the brand of the remote. Do not assume that replacing this board upgrades the radio protocol, adds newer monitored inputs or converts an older operator into a current model. Any required modernization needs its own documented equipment selection.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupplier SKU\u003c\/td\u003e\n\u003ctd\u003eK1A6426-2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer reference\u003c\/td\u003e\n\u003ctd\u003eK001A6426-2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eMain control board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented platform\u003c\/td\u003e\n\u003ctd\u003eLegacy RSL12V \/ RSW12V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadio selection\u003c\/td\u003e\n\u003ctd\u003eSeparate RF-module and frequency verification required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePhotograph the operator nameplate, board number and connected wiring.\u003c\/li\u003e\n\u003cli\u003eCheck the battery, charging path and diagnostic indications before condemning the board.\u003c\/li\u003e\n\u003cli\u003eIdentify the separate radio module and all connected access and protection devices.\u003c\/li\u003e\n\u003cli\u003eConfirm the current replacement revision and manufacturer commissioning requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the main control board.
