Telltale signs of a failed board include no airflow, erratic cycling, blower lockout, or a unit that won't turn on. Dropping in this exact-fit replacement restores steady comfort and protects the rest of your system from voltage problems. It is engineered specifically for the Carrier FB4BSX036000AAAA (3-ton) air handler, with the original terminal layout, relay ratings, and harness connectors so no rewiring is needed. Installation is moderate difficulty and best left to a qualified HVAC technician; always cut power before servicing. Each board ships in anti-static protective packaging and leaves the warehouse same-day on orders before 3PM CST. Opting for an authentic OEM Carrier board rather than a generic substitute maintains factory tolerances, full compatibility, and the longest reliable life for your air handler.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4BSX036000AAAA.\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":62950926123379,"sku":"carrier-control-board-fb4bsx036000aaaa","price":189.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-control-board-fb4bsx036000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
