The transformer converts incoming line voltage to the 24V low-voltage control power that runs the thermostat, control board, and relays. If your fan coil is completely dead, the thermostat display is blank, or the blower won't respond to a call, a burned-out transformer is one of the most common causes. Manufactured to Carrier's exact specifications, this transformer delivers the correct secondary voltage with the proper terminal arrangement, making it a direct fit for the FY5BNF018T05AAAA with no adapters or rewiring. It's a straightforward, beginner-friendly repair for most technicians: kill the power, transfer the leads, and mount — typically under 20 minutes. A genuine OEM transformer protects your control board from the voltage irregularities that cheaper aftermarket units can cause. We stock this part and ship fast. Order before 3PM CST for same-day shipping. Our HVAC parts specialists can verify the correct transformer for your unit if you'd like to confirm before ordering.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FY5BNF018T05AAAA.\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":62942873026931,"sku":"carrier-transformer-fy5bnf018t05aaaa","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-carrier-transformer-fy_193f8b9f-4d5d-4d31-80e1-3b95cb886506.jpg?v=1781473835","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fy5bnf018t05aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
