It delivers the continuous phase shift and voltage boost these motors need to start reliably and run efficiently, making it a critical component for steady cooling performance.\u003c\/p\u003e\u003cp\u003eA weak or failed dual run capacitor is a leading cause of air conditioning breakdowns. Common symptoms include the compressor or fan humming but not starting, hard starting, tripped breakers, warm air from the vents, clicking sounds at the contactor, and a swollen, leaking, or burst capacitor top. Because it serves two loads, a single failed section can knock out the entire outdoor unit.\u003c\/p\u003e\u003cp\u003eChoosing the OEM Lennox \u003cstrong\u003e21W83\u003c\/strong\u003e guarantees the exact dual microfarad and voltage ratings your Lennox equipment specifies. Mismatched aftermarket capacitors can strain the compressor, cause nuisance trips, and shorten component life. This factory-spec replacement installs as a direct drop-in for fast, reliable restoration of full cooling capacity.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081112568179,"sku":"LNX-21W83","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-21W83.jpg?v=1783760436","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-21w83","provider":"National HVAC Parts","version":"1.0","type":"link"}
