When the transformer fails, the entire 24V control side goes dead—no thermostat display, no blower call, and an unresponsive system. Replacing it with the correct OEM transformer restores stable 24VAC output at the proper VA rating and protects downstream controls from undervoltage damage. This unit is matched to the Carrier FA4BNC024008AAAA's primary voltage and secondary load, so it drops in without rewiring. Installation is moderate difficulty for a qualified technician: shut off power, label primary and secondary leads, mount the new transformer, and verify 24V output with a meter before energizing. An OEM-spec transformer avoids the buzzing, overheating, and tripped controls that mismatched generic units can cause. In stock and ready to ship—orders placed before 3PM CST ship the same day so your control circuit is restored quickly.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4BNC024008AAAA.\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":62956762038643,"sku":"carrier-transformer-fa4bnc024008aaaa","price":44.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fa4bnc024008aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
