{"product_id":"liftmaster-q401","title":"LiftMaster Q401 Omni 1 HP Board — Legacy Gate-Operator Service Part","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster Q401 is the Omni 1-horsepower board identified in documented legacy CSW200UL and SL3000UL gate-operator parts lists. It is a separate service board within the appropriate 1 HP electronics arrangement, rather than the operator’s main OmniControl board. Select Q401 by the full operator model, motor configuration, installed board and wiring diagram. This distinction matters when diagnosing a gate that will not run: replacing the wrong board can leave the original fault unresolved, and a 1 HP board alone does not convert a lower-horsepower operator into a higher-capacity machine.\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 CSW200UL 1 HP arrangement\u003c\/td\u003e\n\u003ctd\u003eConfirm Q401 in the exact model’s parts and wiring information.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLegacy SL3000UL 1 HP arrangement\u003c\/td\u003e\n\u003ctd\u003eVerify the installed board and motor configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHalf-horsepower or dual-motor versions\u003c\/td\u003e\n\u003ctd\u003eNo automatic substitution or horsepower conversion is established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMain OmniControl board replacement\u003c\/td\u003e\n\u003ctd\u003eDifferent repair item; Q401 is not the main-board reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLater U \/ UL electronics generations\u003c\/td\u003e\n\u003ctd\u003eA familiar model-family name does not establish board interchangeability.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Board Before Choosing the Repair\u003c\/h2\u003e\u003cp\u003eThe legacy parts list separates the 1 HP board, main control board and motor harness. Have the technician identify which component is involved in the fault before ordering. A motor that does not start may also have a supply, connection, motor or mechanical problem. Record the symptoms and inspect the power path rather than assuming every drive-related problem requires the same circuit board.\u003c\/p\u003e\u003cp\u003ePhotograph the board labels, operator nameplate and existing connections while preserving the wiring information needed for service. Check whether previous repairs changed the electronics or motor arrangement. Restore the specified mounting, insulation and connections using the exact operator diagram.
