A failed transformer cuts all control power: the thermostat goes blank, the blower won't run, and cooling stops, making a correct replacement essential to restore operation. Built to exact Carrier primary and secondary voltage specifications, this transformer is a direct-fit unit that mounts and wires the same as the factory original. Installation is a moderate task for those comfortable with low-voltage wiring: turn off power, photograph the existing leads, move each wire to its matching terminal, and secure the new transformer in place. A licensed HVAC technician can complete the job in under an hour if you prefer professional help. Backed by our genuine-parts guarantee, this transformer delivers reliable, code-compliant control voltage for dependable system performance. In stock and ships same-day on orders placed before 3PM CST, getting your Carrier air handler running again with minimal downtime.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4BNC030010AAAA.\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":62956712460659,"sku":"carrier-transformer-fa4bnc030010aaaa","price":36.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fa4bnc030010aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
