The transformer steps down incoming 120V line voltage to the low-voltage 24V control circuit that powers your thermostat, control board, gas valve, and safety switches. When a transformer fails, your furnace goes completely dead with no thermostat response and no ignition sequence, making this one of the most critical components in the system. Built to Carrier's factory specifications, this part guarantees correct VA rating and mounting fit so your control circuit receives clean, stable power. Installation is a moderate DIY job for anyone comfortable working around line voltage; always shut off power at the breaker before swapping the leads. Most homeowners and technicians complete the replacement in under 30 minutes using basic hand tools. Restore reliable furnace operation and avoid intermittent no-heat calls with the correct OEM transformer engineered for your unit. In stock and ships same-day when you order before 3PM CST, so you can get your heat running fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV024045ACJA.\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":62942837866867,"sku":"carrier-transformer-gb1aav024045acja","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_dd384ddf-7778-4815-a6d4-60838a44bdce.jpg?v=1781473379","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-gb1aav024045acja","provider":"National HVAC Parts","version":"1.0","type":"link"}
