When your system has no power at the thermostat, blows low-voltage fuses, or fails to start, a failed transformer is a common culprit. This is a genuine Carrier replacement engineered to the exact VA rating and primary\/secondary specs of your unit, ensuring stable control power and protecting downstream components. It is a direct-fit replacement for the FA4BNF030008AAAA, mounting in the original location with matching wire leads. Installation is moderate and best handled by an HVAC technician: disconnect power, label and transfer the primary and secondary leads, then mount and reconnect. Using the correct OEM part avoids the voltage mismatches and nuisance trips that aftermarket units can cause. In stock and ships same-day when ordered before 3PM CST, so you can get your fan coil back online fast. Backed by genuine Carrier quality for reliable, long-lasting control power.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4BNF030008AAAA.\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":62956412141939,"sku":"carrier-transformer-fa4bnf030008aaaa","price":74.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fa4bnf030008aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
