On a call for cooling, the low-voltage coil energizes and both poles close together, routing line voltage to the compressor and condenser fan motor in your Lennox outdoor unit. The two-pole configuration switches both legs of the incoming power, fully de-energizing the compressor when the system is idle.\u003c\/p\u003e\u003cp\u003eContactors are consumable wear items, and the \u003cstrong\u003e19J47\u003c\/strong\u003e shows familiar symptoms as it ages: a unit that won't start, a compressor that buzzes without engaging, loud chattering at the contactor, or contacts that weld closed and leave the compressor running past the thermostat's setpoint. Burned, pitted terminals and debris in the contacts are common triggers for failure.\u003c\/p\u003e\u003cp\u003eThe OEM Lennox \u003cstrong\u003e19J47\u003c\/strong\u003e delivers the exact 30A rating, 24V coil pull-in voltage, and terminal layout your Lennox system was designed around. Aftermarket alternatives can differ in coil and contact specifications, shortening service life or causing nuisance faults. Install this genuine part for a precise, dependable fit.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081080783219,"sku":"LNX-19J47","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-19J47.jpg?v=1783760944","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-firstchoice-contactor-2-pole-30a-24v-19j47","provider":"National HVAC Parts","version":"1.0","type":"link"}
