The 25 MFD terminal serves the compressor and the 5 MFD terminal powers the fan, combining two capacitor functions into one durable, sealed housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A degraded \u003cstrong\u003eY9857\u003c\/strong\u003e often causes a humming compressor that fails to start, a condenser fan that won't spin or turns sluggishly, warm air at the vents, short cycling, or nuisance breaker trips. A bulging, vented, or oil-leaking capacitor case is a definitive sign the part has failed and should be swapped out before it stresses the connected motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The genuine Lennox \u003cstrong\u003eY9857\u003c\/strong\u003e delivers the exact 25+5 MFD capacitance and 440V rating your equipment specifies, with US-made build quality for dependable longevity. Substituting a loosely toleranced generic part can shorten compressor life and reduce efficiency. This OEM capacitor guarantees a correct fit and the rated, reliable performance your Lennox system was built to provide.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126560115,"sku":"LNX-Y9857","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-Y9857.jpg?v=1783760324","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-25-5-mfd-440v-round-y9857","provider":"National HVAC Parts","version":"1.0","type":"link"}
