It switches line-voltage power to the compressor and condenser fan motor whenever your Lennox system calls for cooling — the 240V coil pulls both poles closed to energize the outdoor unit and releases them when the demand ends. The lug-style terminals make for a clean, dependable connection to line and load conductors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003eY9374\u003c\/strong\u003e typically develops pitted, burned, or welded contacts and a coil that no longer pulls in reliably. Watch for an outdoor unit that hums without starting, loud buzzing or chattering, intermittent or lost cooling, visible arcing at the contacts, loose or overheating lug connections, or a compressor that stays energized because the contacts won't release.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Choosing the factory Lennox \u003cstrong\u003eY9374\u003c\/strong\u003e guarantees the correct 240V coil, 2-pole 30-amp contact rating, and lug terminal configuration your system expects. OEM specification ensures reliable switching, proper heat dissipation, and a true drop-in fit — safeguarding your compressor and avoiding the miswiring and early failures that come with mismatched aftermarket parts.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081080947059,"sku":"LNX-Y9374","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-Y9374.jpg?v=1783759873","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-2-pole-30a-240v-coil-y9374","provider":"National HVAC Parts","version":"1.0","type":"link"}
