When your thermostat calls for cooling, the 24-volt control coil energizes and closes the contacts, delivering line voltage to start the system. Because it cycles every time the unit runs, the contactor is one of the most important and hardest-working components in the condenser.\u003c\/p\u003e\u003cp\u003eA failing contactor produces telltale symptoms: the outdoor unit won't start, the compressor hums but doesn't engage, you hear chattering or buzzing at the control box, or the contacts weld shut and keep the compressor running continuously. Pitted, corroded, or ant-infested contacts are all common reasons for replacement.\u003c\/p\u003e\u003cp\u003eUsing the OEM Lennox \u003cstrong\u003e19J46\u003c\/strong\u003e ensures the correct amperage rating, coil voltage, and terminal configuration for your specific Lennox equipment. Substitute parts can vary in contact rating and coil sensitivity, leading to premature failure or erratic operation. This factory part installs as a direct, reliable replacement.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081080750451,"sku":"LNX-19J46","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-19J46.jpg?v=1783759916","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-19j46","provider":"National HVAC Parts","version":"1.0","type":"link"}
