It provides the phase-shifted electrical charge that both your compressor (the 75 MFD terminal) and condenser fan motor (the 7.5 MFD terminal) need to start and run smoothly. A single dual capacitor keeps both motors operating at their rated efficiency, making it one of the most critical components in your Lennox outdoor unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003e91W13\u003c\/strong\u003e capacitor often shows up as a compressor or fan that hums but won't start, a fan that spins slowly or only starts when pushed by hand, hard starting, tripped breakers, or a visibly bulging or leaking capacitor top. Because capacitors weaken over time from heat and load cycling, they are one of the most frequent HVAC failure points.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox condensing units are engineered around specific microfarad and voltage ratings. Using the genuine OEM \u003cstrong\u003e91W13\u003c\/strong\u003e ensures the exact capacitance tolerance and 440V rating your system was designed for, protecting your compressor and fan motor from premature wear caused by out-of-spec substitutes. Direct factory fit means proper mounting, correct terminals, and reliable, rated performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081127412083,"sku":"LNX-91W13","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-91W13.jpg?v=1783760387","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-75-7-5-mfd-440v-91w13","provider":"National HVAC Parts","version":"1.0","type":"link"}
