{"product_id":"liftmaster-k001a5747","title":"LiftMaster K001A5747 315MHz Receiver Module — Legacy LA400","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K001A5747 is the 315MHz receiver module identified in the legacy LA400\/LA400S control-box repair list. It receives compatible radio commands for the specified control arrangement. The same manual identifies K001A5747-2 as a separate 390MHz version, making the complete suffix and installed radio system essential when choosing a replacement. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.\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 LA400 \/ LA400S\u003c\/td\u003e\n\u003ctd\u003eMatch the receiver and control-box generation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK001A5747-2\u003c\/td\u003e\n\u003ctd\u003eDifferent frequency in the documented manual; do not omit the suffix.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLater LA400U \/ LA400UL\u003c\/td\u003e\n\u003ctd\u003eNo blanket compatibility established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e315MHz transmitters\u003c\/td\u003e\n\u003ctd\u003eFrequency alone does not establish compatible coding technology.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Assembly and Plan the Repair\u003c\/h2\u003e\u003cp\u003eRecord the existing module number, controller and transmitter information before ordering. The LA400 family spans several generations, and an enclosure label without the control revision can be insufficient. A main control-board failure, damaged antenna or enrollment issue should not be mistaken for a failed radio module.\u003c\/p\u003e\u003cp\u003eAfter service, use the exact receiver and operator instructions to enroll authorized transmitters and verify operation. A replacement receiver does not automatically copy the existing user list or provide access-management service. It also does not add Wi-Fi, myQ connectivity or a newer radio protocol merely by replacing the legacy module.\u003c\/p\u003e\u003cp\u003eAn electrical symptom does not identify the failed component by itself. Have qualified service personnel inspect the supply, wiring, connections and equipment condition before replacing parts. Record existing labels and terminal references with power safely isolated. A replacement should restore the documented circuit arrangement; it should not be used to change operating voltage, defeat a protective function or compensate for a mechanical load that the equipment cannot safely move.\u003c\/p\u003e\u003cp\u003eCompare the delivered item with the approved service reference before installation. The installer must obtain the equipment-specific wiring, mounting and commissioning instructions rather than infer them from the appearance of the part. Keep conductors clear of moving components and reinstall the intended covers. After the repair, check the original complaint and the equipment’s required operating and safety functions; a successful power-up alone is not a complete service test.\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\u003eOrdering reference\u003c\/td\u003e\n\u003ctd\u003eK001A5747\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e315MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented platform\u003c\/td\u003e\n\u003ctd\u003eLegacy LA400 \/ LA400S control box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate frequency version\u003c\/td\u003e\n\u003ctd\u003eK001A5747-2: 390MHz in the cited manual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRole\u003c\/td\u003e\n\u003ctd\u003eReceiver module; not the main control board\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\u003eConfirm K001A5747 without the -2 suffix.\u003c\/li\u003e\n\u003cli\u003eVerify315MHz and supported transmitter coding.\u003c\/li\u003e\n\u003cli\u003eIdentify the control-box generation and antenna.\u003c\/li\u003e\n\u003cli\u003ePlan authorized enrollment and supervised testing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe listing identifies the receiver module.
