The transformer steps incoming line voltage down to the 24V low-voltage signal that energizes the thermostat, control board, and relays. A failed transformer commonly causes a blank thermostat, a dead control board, or a system that won't respond to heating or cooling calls. Built to Carrier's exact primary and secondary voltage and amperage ratings for the FB4BNF018010AAAA, this transformer delivers clean, stable control power and shields downstream components from damage. It installs in the original mounting position and connects with the existing leads for a direct fit. Installation is moderate difficulty involving line-voltage wiring, so it's best for an experienced DIYer or HVAC technician — always switch off the breaker and verify lead connections before powering up. With the correct OEM transformer installed, your control circuit operates reliably once again. In stock and ships same-day on orders placed before 3PM CST so you can finish the job without waiting.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4BNF018010AAAA.\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":62951666811251,"sku":"carrier-transformer-fb4bnf018010aaaa","price":44.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fb4bnf018010aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
