It supplies the continuous charge that your compressor and condenser fan motor need to start reliably and run efficiently, holding steady torque and reducing the electrical strain that wears out motor windings over time.\u003c\/p\u003e\u003cp\u003eA weakening \u003cstrong\u003eY9641\u003c\/strong\u003e shows familiar warning signs: the outdoor unit hums but won't start, the fan or compressor struggles to spin, the system short-cycles or trips the breaker, cooling output falls, and the capacitor casing may bulge or leak. Since capacitance declines gradually, replacing the part at the first symptom protects the far more expensive motor it drives.\u003c\/p\u003e\u003cp\u003eOEM is the right call for Lennox systems. The 45 MFD capacitance and 440V rating of the \u003cstrong\u003eY9641\u003c\/strong\u003e are matched to the equipment's engineered specifications, while generic replacements can drift out of spec and shorten motor life. This USA-made factory part ensures an exact fit and rated, reliable performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081125413235,"sku":"LNX-Y9641","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-Y9641.jpg?v=1783763442","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-run-capacitor-45-mfd-440v-round-y9641","provider":"National HVAC Parts","version":"1.0","type":"link"}
