Because this is a \u003cstrong\u003eMulti-Horsepower\u003c\/strong\u003e motor, the capacitor wiring is critical; always use a brand-new \u003cstrong\u003eDual or Single Run Capacitor\u003c\/strong\u003e (typically 10 MFD or 12.5 MFD at 370V) as specified on the new motor's label. \u003cstrong\u003eDiagnostic Check:\u003c\/strong\u003e Verify the rotation direction before final installation. Most multi-HP motors are reversible; ensure you swap the reversing plugs to match your blower wheel's rotation (CW or CCW) to avoid blowing air the wrong way or overheating the motor.\u003c\/p\u003e\n\u003ch2\u003eCross-Reference\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperseded \/ Legacy:\u003c\/strong\u003e 10M13, 10M11, 19L4301, 80L38, 80L39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Equivalents:\u003c\/strong\u003e Genteq 3465, Fasco D725, Emerson 5460\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLennox Cat #:\u003c\/strong\u003e 19L43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOther Identifiers:\u003c\/strong\u003e 5KCP39LGN654S, Multi-Fit Blower Motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eModel Compatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eG40 Series\u003c\/strong\u003e (Suffixes: UH-24, UH-36, UH-48)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eG50 Series\u003c\/strong\u003e (Suffixes: UH-24, UH-36, UH-48)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eML180 Series\u003c\/strong\u003e (Suffixes: 045, 070, 090, 110)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e80G1 Series\u003c\/strong\u003e (Suffixes: UH045, UH070, UH090, UH110)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eG60 Series\u003c\/strong\u003e (Suffixes: UH-36, UH-48)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":52229635801451,"sku":"19L43","price":175.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/19L32_ca07166a-ac64-4fad-b05a-a204d8ec67c2.jpg?v=1773343483","url":"https:\/\/tophvacparts.com\/products\/lennox-firstchoice-19l43-multi-horsepower-psc-blower-motor-1-6-1-2-hp-115v-4-speed-1075-rpm","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
