When the 24V coil is energized by the control circuit, all three poles close to feed power to the outdoor unit; the higher 40-amp rating and three-pole design suit larger-tonnage or three-phase applications that demand extra switching capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e As the \u003cstrong\u003eY4626\u003c\/strong\u003e ages, contacts pit and burn from repeated arcing, and the coil can lose its ability to pull the poles closed. Look for an outdoor unit that hums but won't run, chattering or buzzing at the contactor, uneven power across the poles, visible arcing or scorching, intermittent cooling, or a compressor that won't shut off due to welded contacts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The factory Lennox \u003cstrong\u003eY4626\u003c\/strong\u003e delivers the exact 3-pole layout, 40-amp contact rating, and 24V coil your equipment was designed to use. OEM specification ensures balanced switching across all legs, correct heat handling, and a precise mounting fit — critical protection for the compressor in high-capacity Lennox units where an underrated substitute can fail prematurely.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081080914291,"sku":"LNX-Y4626","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-contactor-3pole-LNX-Y4626.jpg?v=1783759890","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-contactor-3-pole-40a-24v-y4626","provider":"National HVAC Parts","version":"1.0","type":"link"}
