One terminal supports the compressor while the other supports the outdoor condenser fan motor, delivering the stored electrical charge these motors need to start smoothly and run continuously. A properly functioning capacitor is critical to the efficient, reliable operation of your Lennox air conditioner or heat pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e The compressor or fan hums but fails to start, the outdoor fan spins slowly or stalls, the breaker trips, cooling output drops, or the system clicks repeatedly trying to start. A bulging, swollen, or leaking capacitor top is a clear indicator of failure. Capacitors are a leading cause of no-cooling service calls because heat and age wear them down over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003e72W39\u003c\/strong\u003e is manufactured to Lennox's exact electrical specifications for a guaranteed fit and correct performance. Generic replacements may not match the required microfarad or voltage ratings, which can strain motors, waste energy, and shorten equipment life. The factory OEM part restores your Lennox system to its designed efficiency and dependability.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126986099,"sku":"LNX-72W39","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-72W39.jpg?v=1783760462","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-72w39","provider":"National HVAC Parts","version":"1.0","type":"link"}
