It provides the steady electrical charge that your compressor and condenser fan motor rely on to start reliably and run efficiently, delivering consistent torque while reducing amperage draw and heat inside the motor.\u003c\/p\u003e\u003cp\u003eA failing \u003cstrong\u003eY9640\u003c\/strong\u003e often reveals itself through telltale signs: a humming outdoor unit that won't spin up, a fan or compressor that struggles to start, repeated breaker trips, weak or warm airflow, and a swollen or leaking capacitor top. Because capacitance fades gradually, swapping in a fresh capacitor at the first symptom protects your more costly motor from burning out.\u003c\/p\u003e\u003cp\u003eFor Lennox systems, OEM is the right choice. The 40 MFD capacitance and 440V rating of the \u003cstrong\u003eY9640\u003c\/strong\u003e are matched to the equipment's engineered specifications, whereas generic parts can drift out of spec and cut motor life short. This USA-made factory replacement ensures an exact fit and rated, long-lasting performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081125347699,"sku":"LNX-Y9640","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-Y9640.jpg?v=1783763436","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-run-capacitor-40-mfd-440v-round-y9640","provider":"National HVAC Parts","version":"1.0","type":"link"}
