A dual run capacitor stores and delivers the electrical charge needed to start and continuously power both the compressor and the outdoor fan motor from a single component, keeping your system running smoothly and efficiently.\u003c\/p\u003e\u003cp\u003eWhen the \u003cstrong\u003e19J43\u003c\/strong\u003e capacitor weakens or fails, you may notice the outdoor fan struggling to start, a humming compressor that won't kick on, hard starting, warm air from the vents, tripped breakers, or a bulging, leaking, or swollen capacitor top. A failing run capacitor forces the motor to draw excess current, which can lead to overheating and premature compressor or motor failure if not replaced promptly.\u003c\/p\u003e\u003cp\u003eChoosing an OEM Lennox replacement matters because it is engineered to the exact microfarad rating, voltage tolerance, and physical dimensions your Lennox equipment was designed around. Generic aftermarket capacitors can run outside spec, shortening the life of expensive motors and voiding equipment warranties. The \u003cstrong\u003e19J43\u003c\/strong\u003e restores rated performance and protects your Lennox investment.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126101363,"sku":"LNX-19J43","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-round-dual-LNX-19J43.jpg?v=1783760431","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-19j43","provider":"National HVAC Parts","version":"1.0","type":"link"}
