Because this kit includes a new wiring harness, you must ensure the new leads match the original pin-out for your specific air handler model. Perform a diagnostic check after installation by observing the status LED; if it flashes a code, refer to the included installation instructions (63FA-4A3) to verify the system is communicating correctly with the thermostat. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eSuperseded \/ Legacy:\u003c\/strong\u003e\u003c\/h3\u003e\nHK61EA001, HK61EA002, 322848-401\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eDrawing \/ Alternative Part #s: \u003c\/strong\u003e\u003c\/h3\u003e\nCESO013003-01, 322848-751S\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eWhite-Rodgers\/Emerson Equivalents: \u003c\/strong\u003e\u003c\/h3\u003e\n50A55-843 (Universal alternative, though kit 322848-751 is the direct OEM fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eBrand Equivalents: \u003c\/strong\u003e\u003c\/h3\u003e\nBryant 322848-751, Payne 325878-751 (Upgraded), Day \u0026amp; Night, Tempstar, Kenmore \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eModel Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eCarrier\/Bryant 40YA Series \u003c\/strong\u003e\u003c\/h3\u003e\n(Suffixes: 40YA018300CS, 40YA018300CD, 40YA018300CG, 40YA024300CD)\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eCarrier Comfort Series \u003c\/strong\u003e\u003c\/h3\u003e\n(Suffixes: FB4A, FB4B, FC4A, FC4B Air Handlers)\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003ePayne PF Series \u003c\/strong\u003e\u003c\/h3\u003e\n(Suffixes: PF1MNB, PF4MNA)\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eICP\/Heil\/Tempstar\u003c\/strong\u003e\u003c\/h3\u003e\n(Suffixes: NEMA, NEMS Blower Units)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HVAC Depot","offers":[{"title":"Default Title","offer_id":52451492397419,"sku":"322848-751","price":212.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/original_ae48c9f6-f8a7-48c1-ba5f-7d01f8590c14.jpg?v=1760124128","url":"https:\/\/tophvacparts.com\/products\/322848-751-furnace-fan-relay-control-circuit-board-kit-oem-replacement-for-carrier-bryant-payne","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
