A direct-fit replacement for the Carrier FC4CNB048000AAAA fan coil, it restores the low-voltage control circuit when your air handler is dead or the thermostat shows no power. A failed transformer is a common and inexpensive cause of a completely unresponsive system. Installation is moderate, generally 20-30 minutes: disconnect power, label the primary and secondary wiring, transfer the leads, and mount the new transformer to the original bracket. Always check that the VA rating matches your old part before powering up. Genuine Carrier parts ensure correct voltage and VA specifications for safe, dependable operation. In stock and ready to ship same-day when you order before 3PM CST, so your fan coil is back in service quickly.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FC4CNB048000AAAA.\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":62947722985843,"sku":"carrier-transformer-fc4cnb048000aaaa","price":49.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fc4cnb048000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
