By sensing plenum temperature, it delays the fan until the heat exchanger is warm, then keeps it running long enough to purge residual heat — maximizing comfort, efficiency, and airflow across your Lennox system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failing \u003cstrong\u003eY8847\u003c\/strong\u003e often shows up as a blower that won't start, runs continuously, cycles on and off erratically, or blows cold air at the registers. Contacts can pit and the bimetal sensor can lose calibration over years of thermal stress.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e This control is matched to the specific fan-on and fan-off temperatures your Lennox furnace was designed around. The factory-spec \u003cstrong\u003eY8847\u003c\/strong\u003e ensures the correct sensing element, contact rating, and mounting so the blower engages at exactly the right moment. Aftermarket parts with different setpoints can cause cold drafts, short-cycling, or premature blower wear. Choose genuine OEM for reliable, code-compliant operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081078718835,"sku":"LNX-Y8847","price":89.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-camstat-blower-control-supco-bc7070-y8847","provider":"National HVAC Parts","version":"1.0","type":"link"}
