When the board fails you may experience a non-functioning blower, erratic fan cycling, blown fuses, or a system that won't respond to heating or cooling calls. This genuine Carrier replacement is programmed to the exact specifications of the FB4ANA030010AAAA, providing correct relay sequencing and motor control that universal boards rarely match reliably. Installation is moderate to advanced and best left to a qualified technician: photograph the wiring, move each harness one at a time, and verify the low-voltage terminals before powering up. Always disconnect power at the breaker first. The factory board protects your blower motor and keeps your system's full functionality intact. We carry this part in stock and ship same-day on orders placed before 3PM CST. Fitment guaranteed for the FB4ANA030010AAAA fan coil.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4ANA030010AAAA.\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":62955093786995,"sku":"carrier-control-board-fb4ana030010aaaa","price":189.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-fb4ana030010aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
