Built to precise Carrier specifications, it restores reliable signaling between the thermostat, blower motor, and system relays once the original board fails from power surges, humidity, or burnt components. Telltale signs of a bad board include a blower that won't energize, erratic cycling, or a thermostat the unit ignores. As a direct-fit replacement for the FA4BNC018005AAAA, installation is moderate difficulty: photograph the wiring harness, move each connector one at a time to the new board, and verify the dip-switch and jumper settings match the original setup—about 30-45 minutes for a confident DIYer, or call a qualified technician if you're unsure. Genuine OEM construction guarantees correct relay ratings and a longer lifespan than aftermarket boards. In stock and ships same-day on orders placed before 3PM CST so you can restore comfort fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4BNC018005AAAA.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62956860080499,"sku":"carrier-control-board-fa4bnc018005aaaa","price":224.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-fa4bnc018005aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
