It stores and releases a burst of energy the instant the unit is energized, overcoming the initial inertia before the run capacitor takes over during normal operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A weak or failed \u003cstrong\u003e28W51\u003c\/strong\u003e start capacitor often causes hard starting, a humming or buzzing compressor that won't turn over, frequent tripped breakers, clicking from the contactor, or a unit that struggles to start on hot days. A bulging, leaking, or swollen capacitor top is a clear sign of failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Capacitors must match the exact microfarad (µF) and voltage rating your Lennox equipment specifies. An incorrectly rated replacement can leave the motor under-torqued or overload the windings, shortening the life of an expensive compressor. The OEM Lennox \u003cstrong\u003e28W51\u003c\/strong\u003e delivers the precise capacitance and voltage your system was engineered for, protecting your motor and ensuring reliable starts.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081109750131,"sku":"LNX-28W51","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-28W51.jpg?v=1783763743","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-start-capacitor-28w51","provider":"National HVAC Parts","version":"1.0","type":"link"}
