Its round-case design fits Lennox condensing units and air handlers where a cylindrical mount is specified, providing steady phase-shifting energy on every cycle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a motor that hums but won't start, a condenser fan that turns slowly or stalls, reduced cooling output, higher amp draw, repeated overload shutdowns, or a capacitor that appears swollen, leaking, or ruptured. A weak \u003cstrong\u003e46W18\u003c\/strong\u003e forces the motor to draw excess current, causing overheating and premature wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox specifies the 46W18 at a precise 15 MFD capacitance and 370V rating for correct motor performance. Generic capacitors that fall out of tolerance overload windings, reduce efficiency, and can void your warranty. The factory part guarantees exact fit, rated performance, and verified compatibility with your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081124397427,"sku":"LNX-46W18","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-46W18.jpg?v=1783763417","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-run-capacitor-15-mfd-370v-round-46w18","provider":"National HVAC Parts","version":"1.0","type":"link"}
