This DPST contactor is the workhorse switch inside your Lennox condensing unit, closing two poles of line voltage to the compressor and outdoor fan motor each time the thermostat calls for cooling and the 24V coil pulls the contacts in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include an air conditioner that hums but won't start, a condenser fan and compressor that stay running after the cooling demand ends (welded contacts), audible chatter at the outdoor unit, and burnt, pitted, or corroded contact surfaces. Ant infestation and moisture-driven corrosion are frequent causes of a stuck or non-pulling contactor.\u003c\/p\u003e\u003cp\u003eThe OEM \u003cstrong\u003e24N34\u003c\/strong\u003e matters because Lennox specifies the exact 24V coil, 40A contact rating, and terminal configuration for a safe, direct replacement. Aftermarket contactors with slightly different dimensions or coil resistance can cause chatter, premature wear, and compressor stress. Restore dependable, factory-rated switching with the genuine Lennox part.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081081438579,"sku":"LNX-24N34","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-24N34.jpg?v=1783759901","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-dpst-40a-24v-coil-24n34","provider":"National HVAC Parts","version":"1.0","type":"link"}
