{"product_id":"oem-lennox-contactor-10g19","title":"OEM Lennox Contactor — 10G19","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e10G19\u003c\/strong\u003e contactor is the high-voltage switch inside your outdoor condensing unit that energizes the compressor and condenser fan motor. When the thermostat calls for cooling, 24-volt control power pulls in the contactor coil, closing the main contacts to send line-voltage power to the compressor. The \u003cstrong\u003e10G19\u003c\/strong\u003e cycles thousands of times each season, making it one of the hardest-working electrical components in a Lennox system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e contactors wear out from arcing and heat. Telltale signs include an outdoor unit that hums but won't start, a compressor and fan that won't shut off, chattering or buzzing at the contactor, pitted or burned contacts, and a melted or corroded housing. A stuck or welded \u003cstrong\u003e10G19\u003c\/strong\u003e can leave the unit running continuously, while burnt contacts prevent it from starting at all.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the factory \u003cstrong\u003e10G19\u003c\/strong\u003e is matched to your Lennox unit's coil voltage, contact rating, and amperage draw, ensuring reliable pull-in and safe switching under full load. Generic contactors with mismatched ratings run hot, fail early, and can damage the compressor. Choose OEM for correct fit and dependable, long-term performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081088713075,"sku":"LNX-10G19","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-10G19.jpg?v=1783759913","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-10g19","provider":"National HVAC Parts","version":"1.0","type":"link"}
