It converts incoming 120V line voltage down to the 24V low-voltage power that runs your thermostat, control board, gas valve, and safety circuit. A failed transformer leaves the furnace completely unresponsive: no thermostat display, no inducer, and no ignition sequence, which makes it a top suspect during a total no-heat condition. Manufactured to Carrier's factory specifications, this part ensures the correct VA output and mounting footprint so your control circuit receives stable, reliable power. Installation is a moderate task for those comfortable around line voltage; always shut off power at the breaker before transferring the primary and secondary leads. Most replacements are finished in under 30 minutes with basic hand tools. Installing the correct OEM transformer eliminates intermittent control-power faults and restores dependable furnace operation. In stock and ships same-day when you order before 3PM CST, getting your heat back fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV024045ABJA.\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":62942839079283,"sku":"carrier-transformer-gb1aav024045abja","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-gb_a07c2ab8-6b2f-475a-8013-c41da341a8d2.jpg?v=1781473378","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-gb1aav024045abja","provider":"National HVAC Parts","version":"1.0","type":"link"}
