It steps line voltage down to the 24V control circuit that powers your thermostat, contactor, and control board, restoring reliable operation when your system won't power up or the thermostat goes dead. Built to Carrier's factory specifications, it drops directly into the original mounting location with matching primary and secondary leads, so no rewiring or modification is required. Installation is a moderate DIY job for anyone comfortable working with the air handler de-energized; most homeowners and technicians complete the swap in under 30 minutes with basic hand tools. Using the correct OEM transformer protects your control board and downstream components from voltage problems and nuisance failures. Every order placed before 3PM CST ships same-day from our warehouse so you can get your heating and cooling back online fast. Backed by genuine Carrier quality for long-lasting, dependable performance.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4BNF036000AAAA.\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":62951504642419,"sku":"carrier-transformer-fb4bnf036000aaaa","price":49.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fb4bnf036000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
