Unlike a start capacitor that drops out after startup, this run capacitor stays in the circuit the entire time the motor operates, delivering steady torque and keeping current draw within spec. It is a common wear item and one of the most frequent causes of a Lennox system failing to start or cool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A weak or failed run capacitor often shows up as a motor that hums but won't spin, a fan or compressor that struggles to start, frequent overheating and tripped overloads, higher energy use, or a bulged or leaking capacitor top. Systems may run intermittently or shut down on hot days when demand is highest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Capacitor microfarad (µF) and voltage ratings must match the motor exactly — an incorrect value shortens motor life and hurts efficiency. The OEM Lennox \u003cstrong\u003e46W19\u003c\/strong\u003e is rated to factory specification for reliable, long-lasting performance. Confirm the µF and voltage rating against your existing capacitor and Lennox model before installing.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081089499507,"sku":"LNX-46W19","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-round-single-LNX-46W19.jpg?v=1783763576","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-single-run-capacitor-46w19","provider":"National HVAC Parts","version":"1.0","type":"link"}
