A failed transformer is a common cause of a completely dead control circuit, a blank thermostat, or a system that won't respond to a call for heating or cooling. Replacing it with a genuine Carrier transformer restores the correct secondary voltage and protects downstream components from damage. This unit is matched to the FB4CNP036000AAAA's VA rating and mounting pattern for a precise fit. Installation is a relatively easy repair for a qualified technician: shut off power, note the primary and secondary lead colors, swap the transformer, and verify 24V output. Because it's an OEM part, you avoid the mismatched ratings and wiring confusion that come with generic substitutes. Order before 3PM CST and we ship the same day so you can finish the repair without a long wait. Every transformer ships new and ready to install.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FB4CNP036000AAAA.\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":62950087262579,"sku":"carrier-transformer-fb4cnp036000aaaa","price":44.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fb4cnp036000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
