As a dual-rated part, it provides two separate capacitance values from one housing, keeping both motors energized at their designed efficiency while the 440V rating protects against voltage surges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Capacitors are one of the most common HVAC failure points. A worn \u003cstrong\u003eY9291\u003c\/strong\u003e may cause a compressor or fan motor that hums without starting, a condenser fan spinning weakly or not at all, warm airflow, hard starting, breaker trips, or a capacitor case that is bulging, leaking, or swollen on top. These issues typically strike suddenly and clear up right after replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The USA-made Lennox \u003cstrong\u003eY9291\u003c\/strong\u003e is built to the exact microfarad, voltage, and tolerance specifications your unit requires. Substituting a generic capacitor with mismatched ratings can overheat motors, cut efficiency, and void warranty protection. The factory-specified part guarantees a perfect fit and long-term reliability for your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126691187,"sku":"LNX-Y9291","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-Y9291.jpg?v=1783760329","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-35-5-mfd-440v-round-y9291","provider":"National HVAC Parts","version":"1.0","type":"link"}
