{"product_id":"liftmaster-k94-38028","title":"LiftMaster K94-38028 Power Board Identification Resistor — 1 HP","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K94-38028 is the power-board identification resistor listed for a 1 HP configuration. It is a specific service component for the documented power-board arrangement, not a general replacement resistor selected from a photograph. Match the operator, motor rating and board service information before ordering this small but configuration-dependent electrical part. 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\u003e1 HP power-board arrangement\u003c\/td\u003e\n\u003ctd\u003eUse only where the service documentation identifies this exact reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1\/2 HP configuration\u003c\/td\u003e\n\u003ctd\u003eDo not substitute the separately identified 1\/2 HP resistor.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther board revisions\u003c\/td\u003e\n\u003ctd\u003eAn identical connector or appearance does not establish the correct configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor capacity changes\u003c\/td\u003e\n\u003ctd\u003eThis component is not authorization to increase the installed motor rating.\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\u003eIdentification components must correspond to the equipment configuration the control system was designed to recognize. Establish the existing motor nameplate rating and power-board reference before replacing a missing or damaged resistor. Do not fit a different identification component to mask an overload, change the apparent horsepower or avoid diagnosing a control fault.\u003c\/p\u003e\u003cp\u003eThe ordering description identifies the intended horsepower configuration, but it does not provide an independently verified resistance, tolerance or wattage for selecting a loose electronic substitute. Ask the supplier to confirm the current service item and its application. Preserve the original wiring arrangement and inspect nearby connectors for damage or corrosion during the repair.\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\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\u003eK94-38028\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003ePower-board identification resistor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration designation\u003c\/td\u003e\n\u003ctd\u003e1 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance value\u003c\/td\u003e\n\u003ctd\u003eConfirm from the current approved service specification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelated distinction\u003c\/td\u003e\n\u003ctd\u003eK94-38006 is separately identified for 1\/2 HP\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 motor and operator nameplates.\u003c\/li\u003e\n\u003cli\u003eRecord the installed power-board part number.\u003c\/li\u003e\n\u003cli\u003eConfirm that the approved service list calls for K94-38028.\u003c\/li\u003e\n\u003cli\u003eObtain the correct service procedure rather than guessing resistance from the horsepower rating.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis listing identifies the power-board identification resistor.
