Its dual-rated design combines two capacitor values in a single can, maintaining proper voltage and phase for smooth, efficient cooling performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e As the \u003cstrong\u003e40W01\u003c\/strong\u003e degrades, you may see the condenser fan failing to spin, a humming compressor that won't start, hard starts, weak or intermittent cooling, tripped breakers, or a bulging, leaking capacitor top. A weak capacitor forces motors to draw excessive current, generating heat that can lead to premature compressor failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Your Lennox system is engineered around the precise microfarad and voltage ratings of the \u003cstrong\u003e40W01\u003c\/strong\u003e. Installing a genuine OEM capacitor ensures the correct capacitance tolerance and voltage rating, protecting the compressor and maintaining rated efficiency and warranty compliance. Off-brand capacitors with mismatched values can shorten motor life and cause repeat breakdowns. Choose the authentic Lennox \u003cstrong\u003e40W01\u003c\/strong\u003e for a dependable, direct-fit repair.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081135473011,"sku":"LNX-40W01","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-40W01.jpg?v=1783760441","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-40w01","provider":"National HVAC Parts","version":"1.0","type":"link"}
