{"product_id":"liftmaster-k79-15016-1","title":"LiftMaster K79-15016-1 Commercial Operator RPM Sensor Assembly","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K79-15016-1 is an RPM sensor assembly used in documented LiftMaster commercial door-operator control arrangements. Manufacturer service drawings identify it in several Logic-series operator assemblies, including listed Logic 5 models. It is a speed-feedback service component, not a replacement motor, limit-switch assembly or complete logic board. Confirm the exact operator generation and parts diagram before ordering; a similar symptom or a shared RPM-sensor name does not establish interchangeable fit.\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\u003eListed Logic 5 electrical assemblies\u003c\/td\u003e\n\u003ctd\u003eMatch the complete operator model and drawing revision to K79-15016-1.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel T Logic 3\u003c\/td\u003e\n\u003ctd\u003eThe referenced manufacturer manual lists this RPM assembly; verify the actual equipment configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ca href=\"https:\/\/garage-doorparts.com\/products\/liftmaster-rpm-sensor-assembly\"\u003e041C4398A\u003c\/a\u003e residential RPM assembly\u003c\/td\u003e\n\u003ctd\u003eA different service part; the shared sensing description is not evidence of interchangeability.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMAXUM and other platforms\u003c\/td\u003e\n\u003ctd\u003eNo fit established here; consult the platform-specific service documentation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eAn RPM Fault Requires Diagnosis, Not Just a New Sensor\u003c\/h2\u003e\u003cp\u003eThe control system uses feedback from the drive, so a reported motion or RPM problem can involve more than the sensor itself.
