Engineered to Lennox's exact voltage and microfarad (µF) specifications, it provides the steady phase-shifted current these motors need to maintain torque and run cool. This part is a direct factory replacement for compatible Lennox outdoor units and air handlers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include a system that hums but won't start, a fan or compressor that struggles to spin up, frequent breaker trips, warm air from the vents, or a visibly bulged, leaking, or swollen capacitor top. A failing capacitor forces the motor to draw excess amperage, which shortens its life and can lead to costly compressor damage if left unaddressed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Off-brand capacitors often drift out of tolerance or fail prematurely under real-world heat and voltage swings. The OEM Lennox \u003cstrong\u003eY4605\u003c\/strong\u003e is built and rated to match your equipment's original design, ensuring correct capacitance, safe operation, and full compatibility — protecting the more expensive motors and compressor it supports. Choosing OEM preserves rated efficiency and keeps your Lennox system running as the factory intended.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081134424435,"sku":"LNX-Y4605","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-start-LNX-Y4605.jpg?v=1783763609","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-single-run-capacitor-y4605","provider":"National HVAC Parts","version":"1.0","type":"link"}
