Without a working transformer, your system loses low-voltage control entirely—the thermostat goes blank and the unit won't respond to cooling or heating calls. Built to exact Carrier specifications, this transformer delivers stable, properly regulated control voltage so your system operates safely and reliably. It is a frequent failure point after power surges, shorts, or a stuck contactor, making it a smart part to have on hand. This transformer is matched to the FA4BNF036015AAAA for correct primary and secondary voltage ratings and mounting fit. Installation is a moderate-difficulty job best handled by a qualified technician, since it involves low-voltage wiring connections—typically 30 to 45 minutes with power disconnected. Always confirm wiring matches your original before energizing. Order before 3PM CST and your transformer ships the same business day so you can restore comfort quickly. Genuine Carrier reliability, guaranteed.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FA4BNF036015AAAA.\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":62956260819315,"sku":"carrier-transformer-fa4bnf036015aaaa","price":54.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fa4bnf036015aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
