This single component serves two motor circuits — the 50 MFD side supports the compressor and the 7.5 MFD side supports the outdoor condenser fan motor — delivering the stored charge needed to start and run both motors reliably in your Lennox air conditioner or heat pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e The compressor or fan hums but won't start, the outdoor fan turns slowly or stalls, the breaker trips, cooling weakens, or the unit clicks repeatedly on start-up. A bulging, swollen, or oil-leaking top on the old capacitor is a definitive sign of failure. Because they endure continuous heat and electrical stress, capacitors are among the most common HVAC parts to fail.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003eY9645\u003c\/strong\u003e is manufactured to Lennox's exact capacitance, voltage, and tolerance specifications, guaranteeing correct motor performance and rated efficiency. Generic capacitors can fall out of spec, overheat motors, and shorten compressor life. Choosing the factory OEM part protects your Lennox equipment and restores dependable cooling.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081127051635,"sku":"LNX-Y9645","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-Y9645.jpg?v=1783760365","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-50-7-5-mfd-440v-y9645","provider":"National HVAC Parts","version":"1.0","type":"link"}
