When your thermostat goes blank, the system won't respond to calls for heating or cooling, or low-voltage fuses keep blowing, a failed transformer is a frequent cause. This OEM replacement is built to Carrier's exact primary and secondary voltage ratings, ensuring safe, stable control-circuit power and proper system operation. It is a direct-fit match for the FB4BNF036008AAAA, so no adapters or rewiring are required. Installation difficulty is moderate and best performed by a licensed HVAC technician; plan on 20 to 30 minutes to mount the unit and transfer wiring. Always shut off power at the breaker before servicing the control circuit. Order before 3PM CST and your transformer ships same-day to keep downtime to a minimum. Rely on genuine OEM parts for correct voltage specs, precise fit, and long-term dependability.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4BNF036008AAAA.\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":62951431340403,"sku":"carrier-transformer-fb4bnf036008aaaa","price":59.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fb4bnf036008aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
