A run capacitor stores and delivers a steady electrical charge that keeps the compressor or fan motor running smoothly and efficiently throughout the entire operating cycle. Without a healthy capacitor, your Lennox system loses the phase shift it needs to maintain proper torque, which directly affects cooling performance and energy consumption.\u003c\/p\u003e\u003cp\u003eWhen the \u003cstrong\u003e19J02\u003c\/strong\u003e capacitor weakens or fails, you may notice the compressor or fan struggling to start, a humming outdoor unit that won't spin up, intermittent shutdowns on hot days, higher electric bills, or a bulging and leaking capacitor top. Because a failing capacitor draws excess current, it can shorten the life of the motor it serves if left unaddressed.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e19J02\u003c\/strong\u003e ensures the exact microfarad rating, voltage tolerance, and terminal configuration engineered for your Lennox equipment. Generic substitutes with mismatched capacitance can under- or over-drive the motor and void warranty coverage. Installing the correct factory-spec part restores rated efficiency, protects the compressor, and keeps your system running as Lennox intended.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081124594035,"sku":"LNX-19J02","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-19J02.jpg?v=1783763441","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-run-capacitor-45-mfd-440v-round-19j02","provider":"National HVAC Parts","version":"1.0","type":"link"}
