As a dual-rated component, it handles two circuits in a single housing, making it a critical part of your Lennox outdoor unit's operation. It is engineered to match the exact microfarad (MFD) and voltage ratings your Lennox system was designed around.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A weak or failed capacitor is one of the most frequent causes of air conditioner problems. Watch for a compressor or fan that hums but won't start, a fan that spins slowly, intermittent cooling, tripped breakers, or a bulged, leaking, or swollen capacitor top. Capacitors degrade over time from heat and electrical stress, so failures are common in older systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Using the factory-spec Lennox \u003cstrong\u003e89M78\u003c\/strong\u003e ensures the correct capacitance and voltage tolerances, protecting your compressor and motor from premature wear caused by under- or over-rated aftermarket parts. Genuine Lennox components deliver the reliability and fit your equipment was built for, restoring rated performance and efficiency.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081092481395,"sku":"LNX-89M78","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-89M78.jpg?v=1783760489","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-89m78","provider":"National HVAC Parts","version":"1.0","type":"link"}
