This single component provides two capacitance values, giving each motor the phase shift and torque needed to spin up smoothly and run efficiently under load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e The outdoor fan won't start (or only starts when spun by hand), the compressor hums but won't turn on, warm air from the vents, frequent breaker trips, or a bulging\/leaking capacitor top. A weak capacitor forces motors to draw excess current, leading to overheating and premature motor failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Capacitance rating, voltage, and tolerance must match your motors exactly — an incorrect value strains the compressor and shortens its life. The OEM Lennox \u003cstrong\u003e81W20\u003c\/strong\u003e is spec-matched to your unit's motors, protecting your most expensive components and restoring reliable cooling.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081089466739,"sku":"LNX-81W20","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-81W20.jpg?v=1783760469","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-81w20","provider":"National HVAC Parts","version":"1.0","type":"link"}
