This electromechanical switch controls power to the compressor and condenser fan motor in your Lennox outdoor unit, engaging whenever the control circuit calls for cooling and safely handling the high inrush current these motors draw at startup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003e72P51\u003c\/strong\u003e contactor often shows up as an outdoor unit that hums but won't run, a loud buzzing or chattering at the contactor, visibly pitted, corroded, or burnt contacts, or contacts that weld shut and keep the unit running non-stop. You may also experience intermittent cooling as the worn contacts make poor electrical connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Lennox \u003cstrong\u003e72P51\u003c\/strong\u003e is matched to your system's exact coil voltage and current rating. Using a non-OEM contactor with the wrong coil voltage or lower amp rating risks chattering, overheating, and premature burnout that can cascade into compressor damage. Choosing the factory-correct part guarantees proper fit, reliable switching, and the full rated service life your Lennox equipment was designed for.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081081078131,"sku":"LNX-72P51","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-contactor-2pole-LNX-72P51.jpg?v=1783759866","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-2-pole-120v-30a-72p51","provider":"National HVAC Parts","version":"1.0","type":"link"}
